Soft and comfortable quality prints get popularity Mohammad Nurul Alam Print is a magic word of the fashion throughout the world, especially among the youth. Printing is carried out for producing eye-catchy, trendy, along with visualizing the persona of the wearer, by giving designs on fabric or other materials. Besides, people want comfortable and soft quality print in parallel with unique design or embellishment applied on the garment.
no matter what color or fabric. In reality, make everything ‘soft print’ not on the horizon,” Sumon Hawlader explained. Kinds of soft quality print Demand of soft quality print is snowballing day by day in the apparel market. But not all the range of color and chemical guarantee soft print on fabrics. Some color can melt on the fabric, some can burn the color, and some can create thin layer on the fabric for softer print.
Customers demand in prevalent print trends Soft print on T shirt is a new trend that people are craving for, as it’s comfortable. Some prints maybe eye-catchy, but gets least customer attention because of bulky print or very hard to touch quality in print technique. Characteristics of the soft hand feel print as below: • Soft print can be water base. • Print that goes inside the fiber. •N o layer of print will be seen when touched. •G ood breathability of fabric in the print area. •W ash can make the print softer and more comfortable. Newas Mawla Chawdory, Assistant Manager Merchandising, Asmara Bangladesh Ltd, said, “I was working for an Italian customer for last three years. During the development stage buyer wants different quality print and most of the print they ask to be soft and comfortable to wear.” “So, we always try to use pigment, discharge or other quality print that makes print soft,” Newas Mawla added. Print with soft quality There are different quality/method

print that makes the print soft and comfortable. Also each quality has some limitation when printed on different type of fabric or colored fabric. Some print is suitable on white ground, contrary on colored ground may not be good. Some fabrics are not suitable for all kinds of ink, which requires additional chemicals, making the print process longer and complicated. Sumon Hawlader, Print manager, Alema textile Ltd said, “Most of the buyer wants soft hand feel on the fabric. But, behind the scenario is, not all the fabric, color are suitable to make softer print.” “Sometimes this is becoming a matter of dissatisfaction from buyer’s side because they want the soft hand feeling on everything,
Volume 12, Issue 05
So this is a matter of print expert, to bring out soft print by applying versatile techniques, ensuring premium quality. There are some print quality that can make the print soft and can ensure perfect quality. Discussed below are some top example of soft print. Pigment print It is a common quality that print factories uses for soft hand feel. This quality print also known as water base print because the ink is almost water and can do nice soft print. In most cases white ground fabric is suitable for pigment or water based print color. Water based print also used for process print. Known as Cyan-magenta-yellowblack (CMYK) print also. The advantage of pigment print •P igment print is easy to produce on white ground. • Easy to do any kinds of design. •C MYK or process print can be done easily. •C ost of print less in comparison with other print quality. Limitation of pigment print • Pigment print can only be done

problem if fabric is not properly treated after print.
•F or discharge print need dischargeable dyed fabric. •A ll the color way not dischargeable to dye. Suppose greenish-blue color cannot be dischargeable in fabric dye. Without discharge dye on the fabric discharge print not possible to do. •W hite discharge print cannot be done. In this case print factory uses special chemical. •D ischarge print chemical gives a very bad smell, so garment wash needed to remove bad smell from the garment. Garment wash will increase production cost as well as extra fabric needed for washing purpose. In this case price has to consider carefully. Figure 2: Picture of discharge print. On top of the fabric print is looking nice and back side of the fabric can be seen the penetration of ink. The ink removed the fabric color and stays on the place.
on lighter color fabric. On darker ground this quality print will not be good. •K nit fabric is good to use pigment print. Discharge print Discharge print also a kind of print that gives soft hand feel even on darker ground. The characteristics of this quality print is to burn the fabric color and put the new color. For discharge quality print need discharge quality fabric in color. To apply discharge print, fabric has to be dyed in discharge color. There are some limitations of this quality print.
Reactive print Reactive dye printing is a method of printing a dye or wax by using mixes thereof to create colors. In other word, this quality of print is one kind of dyeing not print exactly. Reactive print done with a binder and a heat-activated printing additive. The dyes directly applied on fabric instead of fabric dye. For this reason the fabric has to be RFD or ready to fabric dye so that reactive ink can go inside the fiber and fiber can suck the color. RFD process includes desizing / singeing / mercerization.
•N o need to dye the fabric because reactive itself one kind of dye.

• Reactive print is costly in compare to other quality. In fine, softer print quality is not always easy but now many print techniques and inks are coming in the market as per market demand. Some new inks can give both good hands feel as well as this is easy to apply on different color ground. But health hazardous matter is getting more concern for any kinds of print chemical. Also color fastness is another concern for the soft quality print. However experiment is continuing to find more effective chemicals that can give solution of good hand feel, color fastness and chemical will be hazardous free also.

High-quality blotch printing on fabric with a digital textile printer Jos Notermans, Manager, Digital Textiles, SPGPrints Blotches have always been very present in many designs for textiles, whether it is for fashion, sports/swimwear or home textiles. With the increased usage of digital textile printers, blotch printing, however, proved to be a challenge for digital textile printers. How can you still enable highquality blotch printing on fabric with a digital textile printing machine? In this blog, I explain why blotch printing is difficult for digital textile printing machines and how you could solve these issues.
Figure 1: By using a multi-pass digital textile printing machine, high-quality blotch printing is possible with a digital textile printer.
What is blotch printing?
1. Problem: clogged nozzle
In the textile industry, the term “blotch” is referring to designs where there is a background color behind the printed motifs. Because of the fact that the motifs need to be printed, normally also the background color is printed. If there were no motifs, the background color would be dyed.
In digital printing, the nozzles in the print heads can get clogged during the printing process (either due to the ink or for instance dust particles cover part of the open nozzle hole).
Blotch printing is commonly used when printing with conventional printers. However, when using a digital textile printer, blotch printing can cause several difficulties. Printing blotches with a digital textile printing machine For a digital textile printer, printing blotches have always been a challenge. Why is it more difficult to print blotches with a digital textile printer than with a conventional machine?
120
When a nozzle malfunctions, it creates a thin, white line in the design since at that point no ink is being transferred onto the substrate, in our case the fabric. That means the printed textile can no longer be used since there is an error in the design. Solution: multi-pass digital textile printing Luckily, there is a way to solve this problem and successfully print blotches with a digital textile printing machine. By using a multi-pass digital textile printing machine, you can mask errors since the lanes that you print overlap each other partly.
This way, any possible failing nozzle in one pass will be covered by good functioning nozzles in the subsequent passes. Only when really many nozzles fail, it might be the case that you still see white lines due to missing nozzles. 2. Problem: the soccer field effect Another common problem with blotch printing on a digital textile printing machine is the so called ‘soccer field effect’. The soccer field effect refers to the different colors of green you see when looking at a soccer field (where it is due to the mowing direction of the grass mowers). The same can occur in textile printing. In digital textile printing, one pass is printed from left to right whereas the next one is printed from right to left. In the printhead carriage, the six print head bars (one for each color) are positioned next to each other. That means

when printing, for instance, a green design (made out of yellow and cyan), in the first pass (from left to right), the yellow drops reach the fabric a little earlier than the cyan drops.
Carbon Footprint
onto the fabric so you prevent the soccer field effect from occurring. Another solution is to double the printhead bars and mirror the positions (for instance an 8-color printer that has the colors mounted in the order Black-CyanMagenta-Yellow-Yellow-MagentaCyan-Black). This means the order of drops reaching the fabric is always the same.
For the next pass, however, the bar runs from right to left which means the cyan drops reach the fabric first before yellow are added. This could cause a slight difference in the green color which creates the soccer field effect. Solution: multi-pass printing with extended color channels
Figure 2: Jos Notermans, Manager, Digital Textiles, SPGPrints.
Again, multi-pass digital textile printing can help solve this problem. By having printing passes overlap — for example, by moving
only up ¼ of the distance that you would previously move up (4-pass printing) — you effectively mix the order of the drops coming
Although this is a very suitable solution, it will also increase the cost of the printer as double the number of heads and electronics are needed. From that, the carriage will also get larger and heavier which requires a stronger frame for the printer.
MIT engineers develop a sustainable method to reduce carbon footprint Desk Report Daily global carbon emissions has increased about a billion tons more than the previous year. And today the industrial sector, namely the manufacture of plastics, iron, and steel are the biggest source of global energy consumption and most of these result to carbon dioxide as a byproduct. A team in MIT chemical engineers developed a sustainable method by using electricity to separate water into oxygen, protons, and electrons. The method uses electricity to run the reaction while removing carbon dioxide as a byproduct. The team is composed of team leader MIT postdoc Kyongsuk Jin. Other researchers include graduate students Joseph Maalouf, Nikifar Lazouski, and Nathan Corbin, and postdoc Dengtao Yang. "What isn't often realized is that industrial energy usage is far greater than transportation or residential usage. This is the elephant in the room, and there has been very little technical

places, but the researchers tend not to think about the embedded energy and carbon dioxide footprint," Manthiram added.
progress in terms of being able to reduce industrial energy consumption," said Karthish Manthiram, an assistant professor chemical engineering and the senior author of the new study. The three-membered ring epoxide is the raw material in producing detergents, polyester, and antifreeze. "It's impossible to go for even a short period of one's life without touching or feeling or wearing something that has at some point in its history involved an epoxide. They're ubiquitous," Manthiram said. They're in so many different
Volume 12, Issue 05
Chemicals with the top carbon footprints include a number of epoxides. Ethylene oxide, one common epoxide, produces the ‘fifth-largest carbon dioxide emission of any chemical product.’ There are many chemical steps involved in manufacturing epoxides. This process requires a large amount of energy as it needs to under pressure which is 20 times greater than atmospheric pressure and at nearly 300 degrees Celsius. Their findings were published on April 9 in the Journal of the American Chemical Society. They have already filed a patent on this technique and is enhancing the synthesis efficiency for adaption on a large-scale, industrial use.

3D Printing
Leading footwear brands making significant investments in developing effective digital footwear Desk Report 3D printed footwear market is growing globally and is set to grow into a 6.3 billion overall revenue opportunity over the next 10 years (according to the latest report from SmarTech Publishing).
with traditional manufacturing processes, which helped push the limits of innovation faster. Nike has also reportedly been working with Prodways on developing a line of 3D printed midsoles using the company’s SLS technology and TPU materials.
And leading footwear brands are have been making significant investments in developing effective digital footwear manufacturing workflows. Leading brands such as Adidas, New Balance, Nike, Under Armour and Reebok coming out with their take on it and producing different footwear final parts and products, relying on different technologies and materials. Adidas is in the forefront of the industry in 3D printing shoes. Adidas is the brand that has made the most significant steps toward implementing additive manufacturing in footwear mass production. Adidas recently released their sneaker: the Alphaedge 4D that mixes traditional manufacturing with 3D printing. This sneaker was produced in their ongoing collaboration with the 3D startup Carbon by the end of 2018 Adidas introduced 100.000 pairs of their new shoes and are planning to push the technology even further in 2019 aiming to produce in the

millions in the coming year. “We have a really aggressive plan to scale this,” stated James Carnes, vice president of strategy creation at Adidas, last year. James Carnes continues; “We are scaling a production. The plan will put us as the (world’s) biggest producer of 3D printed products.” Nike was among the first companies to make intensive use of 3D printing in high-performance product development, using the technology for quick iterations of functional parts. 3D printing allowed to test, iterate and create shapes not possible

New Balance was one of the first companies to experiment with 3D printing for a number of applications. First, it unveiled the Zante Generate shoe with 3D printed midsole in partnership with 3D Systems in 2016. Produced by SLS using the Duraform TPU elastomer material, the Zante Generate was the first 3D printed running sneaker to be made commercially available The company is working toward increased use of 3D printing as a means to automate (and possibly onshore) midsole manufacturing processes. Under Armour’s UA Architech is a line of shoes that features a 3D printed midsole. The first Architect line product was introduced in 2016, designed with Autodesk software and produced using EOS SLS technology. Reebok debuted the Liquid Floatride Run shoe, made using the same technology it introduced in its Liquid Factory. The process is essentially a 3D drawing process. Of course the numbers that are producing with 3D printing today are tiny if compared to the overall footwear market. But the technology gives the designer more freedom and can give the consumer looking for a more unique and fashion forward shoe a way to express themselves better.

Vasudevan added that there is a need to have specialized converting sector. He further added that exploring the market and strengthening the marketing aspect should take priority.
That was followed by a major business event, “Link with India.” Probably, this event was ahead of its time as the technical textiles sector was getting started with wide spread awareness then. Currently, India is going for a high gear to push technical textiles forward due to the stressful situations faced by the spinning sector due to cotton price Bangladesh Textile Today |

Those mills that have invested in wind power and modernization are surviving, but still needs to focus on diversification, added Prakash Vasudevan. This scribe has been emphasizing on

In this scribe’s opinion, there is an immediate need to create a flow channel for technical textiles fabrics (downstream) that can be translated into value-added products, used by consumers. Additionally, creating collaborations between advanced nations in this field such as Germany and the United States will pave the way for the growth of this sector. 127

Air pollution, a great source of printing inks Engr. Ahmed Javed Jamal, Head of Technical Operations & Marketing, Silkflex Bangladesh Ltd Introduction
Air quality further declines during the dry months—from October to April—but improves during the monsoon. We can make this polluted air into air ink which will be an asset for ink industry. Air Ink invented by Graviky Labs, is already manufactured in India for commercial basis. How air ink is introduced? Founded by Graviky Labs, a spinoff group of MIT Media Lab, air ink produces its materials through a step-by-step process which primarily involves capturing of emissions, separation of carbon from the soot, and then mixing of this carbon with different types of oils and solutions. In 2013, the Fluid Interfaces research group, at the Massachusetts Institute of

Bangladesh, one of the most densely-populated countries in the world, has been struggling with air pollution for long. “Dhaka is the second worst capital city in terms of air quality,” according to World Air Quality Report 2018 released by Greenpeace and Air Visual. The report also said that air pollution will cause around 7 million premature deaths globally in 2019 and have a major economic impact. Brick kilns, vehicles run on fuel containing higher levels sulphur, as well as construction work have been identified as major sources of air pollution.

pipe of cars, chimneys, and generators. The guys from the lab created a device that captures soot already emitted from vehicles. When the device is attached to the vehicle, it captures pollutants. After only 45 minutes of driving, the device can produce 1 fluid ounce of ink. Finally, when the heavy metals and carcinogens are removed from it, there is a purified carbon-rich pigment left, perfect for ink. Use of air inks: • Permanent marker • Whiteboard marker ink • Calligraphy ink • Acrylic emulsions • Screen printing ink • Inkjet printer ink Is it possible to produce air ink in Bangladesh? Dhaka ranks highly amongst the world’s major cities in terms of poor urban air quality. Substantially reducing air pollution could save up to 3,500 lives and

avoid up to 230 million cases of respiratory diseases annually in Bangladesh. In economic terms, this is equivalent to around US$ 500 million in savings due to reduced health care costs and increased productivity per annum. Brickfields in Bangladesh expel over 9.8 million tons of greenhouse gases into the air annually due to a combination of old technology, weak environmental legislation and enforcement and lack of corporate responsibility. So it is high time for Bangladesh especially for Dhaka city to make a concrete solution of air pollution. If government and reputed universities of Bangladesh (eg:BUET,BUTEX,University of Dhaka, North South University,Brac University and other reputed university) take proper steps for ‘Air Ink Project’, it will not only reduce the air pollution but also reduce the import of different types of printing inks which will make our revenue a stable position.
organization and the responsible ministry of Bangladesh government can inspire the entrepreneurs to invest into these eco-friendly environment savings project. The market size of inks (marker ink, screen printing ink and inject printer ink) is about Tk760 crore of the local manufacturer and share of import is 1,500 crore. These quantities of demand are met by import mostly from India, China ,Malaysia, Korea and other countries. If ‘Air Ink Project’ is successfully done in Bangladesh, automatically, we will be beneficiary by reducing the import of all types of these inks. Also, we can save our environment by establishing these air ink production process.

The environmental concerns
Factory tales- visit to printing factories in Bangladesh Charlie Taublieb, Taublieb Consulting-Textile Screen Printing Consultant The following is an observation based on visiting several textile factories on my visits to Bangladesh. They should be viewed as positive critiques to generate some changes.
1. Too many people per machine
To begin with, most of the factories I visited were all quite large and very busy. All of the factories had multiple automatics, lots of print table and combination screen and digital machines. Most were printing with water-based inks, but a few were also using silicone.
4. Too much flashing with too many flash units per machine
For the most part, the factories were well organized and very clean, much cleaner than most of the large and small shops in the USA. The downside of what I saw was inefficient production with the following issues:
130
2. Too many of the same screens per color 3. Too many print strokes per color
5. Some mesh counts were too high based on the type of ink and desired results 6. Sampling was done on tables and production on machines • Samples were done with the screens on contact with the garments giving a different result than on automatic press • Different mesh counts were used during sampling and those were to be used on the automatics • The number of times a garment
was printed and flashed was at times different than what was to be used during the production run 7. Documentation was missingsome very key elements I realize that the clients of these companies have very definite requirements, but it seems that none of the factories had a research and development department to try and work out better and faster ways of giving their client the required results. Based on what I was told, that the government has raised the minimum wage by almost 60%, the factories really need to address many of the points I have outlined above or risk losing a lot of money. I enjoy coming to Bangladesh and look forward to my next visit.

performance and unattended printing. Engg. Shafiqur Rahman said Bangladesh textile industry is passing a hard time due to gas and electricity price hike, new wage board, etc. so hopefully SPGPrints will give us some economical technology solutions in the coming days. What we produce, most of them goes to EU countries and we use EU machinery to produce them. So, if the EU machine price is high then I think we also should get a bit more price from the EU buyers, he concluded.
Spinners need to act proactively to overcome current catastrophe Abdul Wadud, CEO & Management Consultant, TRANSFORM It all started in October 2018 with the context of Brexit, slower demand for garments and and higher level of unsold garments in the stores. Then it was carried through by comparatively higher level of currency devaluation of competing countries and dumping yarn price from outside countries, followed by 51% wages increase for the readymade Bangladesh garment industry, higher tariff on gas, the major raw material for captive power generation for spinning industry, the trade war among the two major economies of the world-USA and China. The battle between USA and China is a battle of USD 100 billion Vs. USD 500 billion exports in between those two countries. Who would win the battle, only God (Allah) knows but it is evident that it has contributed immensely into increased volatility in the international trade, adversely affected world economic growth, distorted the stability of money market and capital market. So far, we have passed almost eight
months and it is now the time to settle down. Is not it?
The battle between USA and China is a battle of USD 100 billion Vs. USD 500 billion exports in between those two countries. So far, we have passed almost eight months and it is now the time to settle down. Is not it? It is a part of my daily activity that I collect different data and analyze those in my own way that I feel is interesting since I started my career in 1997 after studying Finance for long six years. And I wondered how close my analysis was with respect to
actual as I started my career in the spinning industry. I sometimes wondered is it gut feeling? Nah! Sounds stupid and as I did not have the answer I was happy to remain stupid. Only in a recent year, I came to know about how I could do it from Mel Robbins who I think is a great motivator. The way my ‘Reticular Articulated System’ signals about spinning business in Bangladesh market is that the situation would remain the same for rest of 2019 and it is very important to design some macro and micro strategies in order to minimize damage. So, I would highly recommend the spinning community to wake up who are still after the ‘Low hanging fruits’ since the beginning of the biggest spinning catastrophe in Bangladesh since independence that started back in October 2018 and expecting that soon it would be over. It is high time for action with the future in mind and I am very optimistic about the spinning industry.
As a reference or recommendation you can go through my following two articles that were published in Textile Today: Article in “Textile Today” October, 2018 issue. Topic “Strategies to secure competitiveness in Spinning in Bangladesh” Article in “Textile Today” March, 2019 issue. Topic “An analysis of the current state of spinning industry in Bangladesh and seeking a way forward to cultivate success and assure sustainability”
