1.0 Introduction “Textiles affect every part of our lives” – Balton Godfrey. How that textile performs will determine the end-use of a product and whether or not it is fit for purpose. The fashion industry spends millions of pound per year on testing to ensure textiles are up to the standard set by institutions such as British Standards, ASTM International Standards, and ISO International Standards. Some of the reasons that these testing institutes exist, other then ensuring that textiles comply to the end-use specifications, is to study the various affects of treatments on the final fabric (such as colourfastness and washing recovery), to ensure the effectiveness of the process development, and to help investigate cause of failure and customer complaints if the product is unsuitable (Davis 2015).

Testing is carried out in controlled conditions for consistency of results(Figure 1.1). The standard atmosphere for testing textiles is 20°C plus or minus 2°C and a humidity of 65% plus or minus 4% (Davis 2015). All accredited laboratories must follow these conditions. There are 7 areas to test these are durability, aesthetics, comfort, care, environmental resistance, safety, and biological resistance. All textiles are tested for the above, however they do not need to pass all, depending on the end-use. Certain end-uses such as infant grows must adhere to strict flammability standards, whereas an adult’s blazer does not. This report will investigate the results of testing on a cotton knitted fabric, and whether or not the end-use chosen is fit for purpose.

Figure 1.1 Textile Testing Lab

2.1 The Fabric

The fabric supplied for testing was received and the fabric hand was tested. It was determined that the fabric was a knit, soft, smooth, with a medium fullness that draped well. Immediately the consensus was that this fabric would make a good cardigan or crew-neck jumper. The first few tests were conducted and it was determined that the fibre was cotton and the structure was a 1x1 Rib Knit (Box I). After these initial tests the end-use decided on was a cardigan with a drape front.

The end-use of the cardigan over the crew-neck jumper was determined by the drapability of the fabric. This style of the long drape-front cardigan (Figure 1.2) is a staple in many stores year round. Although lightweight cotton fabric is usually used in the spring/summer seasons, this style of cardigan can be used as a layering piece in the winter, especially in countries with milder weather, such as the UK. With the end-use in mind the next step was to undertake the standardised tests to ensuring the fabric was indeed fit for purpose.

Figure 1.2 Drape Front Cardigan from Aritzia

2.2 The Testing To determine the fibre content, 2 tests were carried out; the longitudinal image under a microscope (10x magnification) and the burn test. Under the microscope the fibre resembled ribbon like strands, which is a trait of cellulosic fibres (Appendix 1). However to fully identify the fibre the burn test was carried out, with the fibre burning rapidly and the smell of burnt paper it was determined that the initial finding was correct and that the fibre content was cotton (Appendix 1).

In accordance with the Fabric Performance specifications, the tests carried out for knitwear are:

•Bursting Strength •Pilling

•Stability to Washing

•Colour fastness to Washing

•Colour fastness to Rubbing Other areas of interest are:

•Resistance to Abrasion •Resistance to Snagging •Drape Coefficient

The Bursting Strength test determines the tensile strength of the fabric. The fabric is placed on an apparatus and clamped onto a diaphragm. Pressure is then applied to the diaphragm until the fabric bursts. The requirements set out by BS, EN, and ISO are 250 kPa with a distention of 30mm (Davis 2015).

The results of the test undertaken by the author has a force to burst of 277.5 kPa and a distention of 26.5mm. This fabric was on the borderline of passing the test. A suggestion for creating a stronger fabric could be to introduce another fibre into the fabric. Silk would be an excellent fibre to incorporate into the fabric as it has an exceptional burst strength as seen with the results in Box H (Appendix 3).

The Pilling test requirements set out by BS, EN, and ISO require a grade 3-4 to be achieved after 3 hours of testing (Davis 2015). The test undertaken by the author was the pill box method(Figure 1.3). This method uses samples mounted on polyurethane tubes and these are then tumbled around in a cork lined box rotating at 60 revs/minute. The results of the test were both 4 in the courses and wales, meaning the fabric passed this particular test.

Figure 1.3 Pill Box

One of the biggest reasons for returning a product is that is has shrunk in the wash. To avoid this outcome the Stability to Washing test is undertaken. BS, EN, and ISO require the fabric to have shrunk or stretched no more then +/- 5% (Davis 2015). The results undertaken by the author revealed that although the width passed at 4%, the length failed at -16%. A suggestion could be that the fabric be pre-shrunk before being produced into a garment.

Another common reason for clothing to be returned is the colour bleeding, whether that be from washing, or just rubbing against a light coloured object such as a couch. The regulation results for Colour Fastness to Washing set out by BS, EN, and ISO are maximum of a shade change of 4 and a maximum stain change on the multi-fibre strip of 4 at a maximum washing temperature of 50°C (Davis 2015).

The results undertaken by the author was washed at a temperature of 40°C with a result of shade change of 4. The staining on the multi-fibre strip all passed with a 4/5 with the exception of cotton which has a staining of 2/3 (Figure 1.4). A suggestion could be to wash the fabric at 30°C to see if the staining still occurred, or to change the dye from direct to dispersed dye. Although the dispersed dye would not give as intense a colour it is more stable.

Figure 1.4 Multi-Fibre Results

Colour Fastness to Rubbing test regulations required by BS, EN, and ISO are very similar to Colour Fastness to Washing with a maximum change of 4 for dry and a maximum change of 3-4 for wet (Davis 2015). The test undertaken by the author used a crockmeter with a piece of dyed fabric and rubbed it against a piece of cotton lawn for 10 seconds. It revealed that the fabric passed with a 5 for dry and a 4/5 for wet (Figure 1.5). This test would have to be undertaken again if the dye was to be changed to dispersed dye.

Figure 1.5 Rubbing Test Results

Resistance to abrasion is similar to pilling which measures the durability of the fabric. The test undertaken by the author used the Martindale abrasion test (Figure 1.6) at 5ooo revs and 20,000 revs. The results were a 3 after 5000 revs, which left some pilling on the surface.

However after the 20,000 revs the result was a 4, indicating that the pills would fall off with time. This indicates that the fabric would correct itself after a time in high abrasion areas. Another durability test is the Resistance to Snagging. This test undertaken by the author used the mace method for 600 revs. The results were are 5 in the length and a 4 in the width indicating a very strong resistance to snagging.

Figure 1.5 Martindale Abrasion Test

For the aesthetic of the end-use of the fabric, a draped front cardigan, the Drape Coefficient was very important. The test undertaken by the author used the Cusack Drape tester (Figure 1.6) (Davis 2015). A circle from the fabric is cut out and placed in the tester, then the lid is lowered. A light is turned on and a piece of circular paper is placed over the top of the box.

The shadow of drape is traced, then the process is repeated on the other side of the fabric. The results are then calculated with the higher percentage fabrics proving stiffer and having less drape, whereas the lower percentage indicates a limper fabric with better drapability. The results of the test were 17%, indicating the initial consensus was correct that the fabric had excellent drape.

Figure 1.6 Cusack Drape Tester

Comparing the Dimensional Stability test results; only one of the three knitted fabrics passed this test.

Box K was made of a Thermoplastic Polyester and was the only fabric to pass the Dimensional Stability test. Although Box K also passed the Colour Fastness to Washing, with the changes noted above the fabric from Box I should pass all regulatory test set out by Testing Standard companies. These tests help to determine whether the end-use for the product is fit for purpose, or if an alternative for the product needs to be sourced.

2.3 Care Label Fibre content labelling (Figure 1.7) is compulsory under the ‘Textile Products (Indications of Fibre Content) Regulations of 1986’ (Taylor 1990).

Items that must be included are: Country of Origin, Care Instructions (washing), Fibre content, and in certain countries such as Canada an identifying number (known in Canada as a CA number). For the fabric under consideration the care label would be as follows:

Figure 1.7 Care Label on Clothing

•Made in the UK (assuming it was manufactured in that country) •100% Cotton •Machine Wash 30°C – as the Dimensional Stability and the Colour Fastness tests did not meet the standard of BS, EN, and ISO results at 40°C, even if the fabric was pre-shrunk before being made into a garment and the dye was changed, precautions would have to be made. Washing the garment at 30°C could allow the garment to shrink less and have less colour loss •Lay Flat to Dry – as the fabric did not meet the Dimensional Stability standard of BS, EN, and ISO, putting the garment in the dryer could further mishape the garment •Do Not Tumble Dry – as the fabric did not meet the Dimensional Stability standard of BS, EN, and ISO, putting the garment in the dryer could further mishape the garment •Dry Clean – although more tests would have to be carried out, many cotton cardigans have the option of being dry-cleaned •Iron on Low Temperature – with the Dimensional Stability in question, adding too much heat could damage the garment, so the iron should be kept at a low temperature •Do Not Bleach - the garment should not be bleached as it is colour treated This is the standard care label for the garment as is. If, as discussed, a fibre such as silk was to be added in, the care label would have to be amended.

3.0 Conclusion Over the past few months the fabric that was received in Box I has been tested in many different ways to determine if the original end-use of the cardigan was indeed fit for purpose. The fabric only failed in two of the Fabric Performance specification for knitwear tests to which it was subjected; Dimensional Stability and Colourfastness to Washing. The Dimensional Stability could be fixed by pre-shrinking the fabric before production. As for the Colour Fastness to Washing, the test could be undertaken again with direct dye under stricter testing conditions, as the test done the first time could have had the incorrect heat applied, or as it was dyed with different fabrics could have interfered with the dying process.

Alternatively the dye bath could be changed to a dispersed dye. Although direct dye yields a more vibrant colour than dispersed dye, the latter could yield a more stable dye. With these minor changes taken into consideration and with the outstanding results in the other tests such as Resistance to Abrasion, Resistance to Snagging, and Drape Coefficient the cotton 1x1 rib the conclusion from the test is that; yes the fabric is fit for purpose.

Comparison of Burning Characteristics after FR finish Original Fabric

Finished Fabric

Burns quickly and ends up shrinking as it burns and it creates a lot of smoke- which does not give a lot of time to take the garment off

Self-extinguishing and the ends burns- this gives time to take the garment off and save the skin

Comparison of Burning Characteristics after FR finish Original Fabric

Finished Fabric

Burns very quickly, turns into a black bead, sticky, flame ignites and gets smaller rapidly. Not much of the fabric remains.

Once the fabric is moved from the flame it stops shrinking, Doesn’t ignite a flame and slower shrink rate. More of the fabric remains.
