Studies of Stretchable Airjet Textured Yarn – A Experimental Review Prof. Ashwin Thakkar1 Prof. Vaishali D. Shah2 Mr. Manish Bhatia3 1,2 Professor 1,2,3 Department of Textile Technology 1,2,3 L. D. College of Engineering, Ahmedabad Abstract—Airjet Texturing process is mechanical method to produce bulkiness in the yarn. Also the feed yarns need not to be restricted to synthetic yarns. The air textured yarns resemble spun yarns in their appearance and physical charactertics. The air-jet Texturising process is the most versatile process of all the yarn texturizing methods in that it can blend filament together during process. As it is also know that airjet textured yarn is having almost similar properties of cotton yarn so by introducing lycra into it the strength and Stretchability of the yarn and fabric can be increased and also better appearance can be seen.

Key words: Airjet Textured Yarn, Lycra Blend Airjet Textured Yarn, Stretchable Textured Yarn

II. EXPERIMENTAL SETUP A. Preparation of samples:  

Samples are prepared on Airjet SSM DP – 5 Machine, Tsudakoma weaving machine and Zhexing Knitting machine Some parameters for the samples are tried to keep same such as yarn denier is kept constant, weave and other parameters are kept constant in weaving and in knitting courses are kept constant, the only change is done is the percentage of lycra in the yarn.

I. INTRODUCTION Most Natural fibres have a certain amount of crimp and waviness that helps to impart some degree of bulkiness, a property considered very desirable in textile fabrics. The texturing of thermoplastic yarns has been one of the most exciting developments in the field of textile processing. This process has completely revolutionized the use of nylon and polyester yarns in the men’s and women’s apparel, rug and carpet, and hosiery and knitting industries.

Texturising helps improve the pill and crease resistance and confers better dimensional stability, fuller and better appearance, great durability, Flexibility, better covering power, easy to wash, dry readily, high abrasion resistance, strength and bulkiness.

As in a survey it is seen that about 20% to 25% of total cloth production contributed only by Air Textured yarn/fabrics and now days it is widely used in technical textile field such as in tyre, belt, golf bags, filter etc.

Fig. 1: Graph 1: - Stress Strain Behavior of yarn 1) From the Stress Strain Behavior test results: It is seen that force required to break the Airjet textured is more as compared to the Draw Textured yarn, From the above graph it can be seen that the force(gm) increases with the increase in the percentage of increase of lycra in Air textured yarn and draw textured yarn.

Also the percentage of Elongation at break improves with the increase in the lycra percentage in the yarn. But here also it can be clearly seen that Elongation at break is more in Airjet Textured yarn as compare to Draw Textured yarn.

Fig. 2: Graph 2:-Tensile Strength of Woven Fabrics 1) Results Tensile strength of Woven Fabric:From the above graph it can been seen that the tensile strength of sample 1 is improved as compare to other samples in warp direction. But comparing the sample 4 and 6 the strength is improved in sample 4 in warp direction and also comparing the sample 5 and 7 the strength of sample 5 is improved in warp direction. Now again comparing the sample 4 and 6 in weft direction the force required is more for sample 4 as compare to sample 6 and if we compare sample 5 and 7 in weft direction then the force required is more for sample 5. So it can be concluded that if we increase the percentage of Lycra in Airjet Textured yarn the Tensile strength of the fabric is improved.

Fig. 3: Graph 3: Tearing Strength of Woven Fabric 1) Results of Tearing Strength: From the observation results it can be seen that the tearing strength of sample 4 is more as compare to sample 6 in both directions while comparing sample 5 and 7 the tearing strength of sample 5 hence it can be concluded that by increasing percentage of lycra improvement the strength of fabric made with airjet textured yarn.

Fig. 4: Graph 4: Stretch of Woven Fabric

Graph 5: Recovery of Woven Fabric 1) Result of Stretch and Recovery of Woven Fabric: From the above graph of Stretch it can be concluded that stretch in the fabric is almost same but comparing the sample 4 and 6 the stretch in sample 4 is more as compare to sample 6 in both warp and weft way direction, also comparing sample 5 and 7 the stretch is more in sample 5 in both warp and weft direction.

From the above graph of Recovery it can be seen that recovery is more in airjet textured yarn fabric samples as compare to draw textured yarn samples. The recovery improves with the increase in lycra percentage in both the yarns in both direction. Now comparing sample 4 and 6 in warp and weft direction, sample 4 has more recovery as compare to sample 6. Also considering the sample 5 and 7 the recovery of sample 5 is more as compare to sample 7 in both warp and weft directions. Hence it can be concluded that the stretch and recovery is improved in airjet textured yarn fabric samples as compare to draw textured yarn fabric samples.

E. Stretch and Recovery of Knitted Fabric: Fabric Fabric Stretch(%) Recovery (%) After 10 sec After 10 Sec 01 (ATY) 72.12 82.36 02 (ATY 2.5%) 117.69 92.13 03 (ATY 3.0%) 125 92.34 04 (ATY 3.5%) 135.12 92.56 05 (ATY 4.0%) 143 93.45 06 (DTY 3.5%) 120.64 90.71 07 (DTY 4.0%) 130 91.21 Table 6: Observation Table for Stretch and Recovery of Knitted Fabric Samples no.

Fig. 6: Graph 6 Result of Stretch and Recovery of Knitted Fabric 1) Result of Stretch and recovery of Knitted fabric: From the above graph it can be seen that stretch of Airjet textured yarn samples improved with the increase in percentage lycra as compare to draw textured yarn samples.

Here now comparing the sample 4 and 6 the stretch of sample 4 is 135.12 while sample 6 is 120.64, also comparing the sample 5 and 7 the stretch of sample 5 is 143 and sample 7 is 130. So by comparing these samples it is observed that stretch of Airjet textured samples is improved as compare to draw textured yarn samples.

Now in case of recovery, the recovery of the Airjet textured yarn samples is almost same in all cases of lycra also the recovery in the Draw Textured yarn samples is also almost same but it can be seen that the recovery percentage is improved in airjet textured yarn as compare to draw textured yarn samples.

IV. CONCLUSION The yarn samples were prepared using same denier of polyester, only the percentage of lycra is change in the yarn in airjet and draw texturing process. Hence different samples were prepared and various test are carried out in my experimental work of the thesis. It can be concluded that as the percentage of lycra is increased the stretch and recovery of airjet textured yarn is more as compare to draw textured yarn.
