Knitted sweaters are labor-intensive industries. Due to China's low labor prices and preferential investment policies, many foreign companies' orders are available domestically. China is a big country in the production of knitted sweaters, but it is not a strong country. Relevant experts believe that if we want to make our sweater industry bigger and stronger, we must increase the added value of our products as soon as possible and make our own brand. Applying some new materials to knitted sweaters is undoubtedly an important way to produce high value-added products.

With the development of individualized clothing, the fiber raw materials of knitted sweaters are no longer limited to the warmth of wool and acrylic fibers, but the new and certain characteristics of the fibers are applied to the sweater design in order to achieve different styles. . The development idea of ​​PTT spun yarn is to make full use of the excellent performance of various fibers, to play the role of complementing each other, and further improve the application advantages of PTT fiber in the field of knitted sweaters.
The PTT spun yarn used to develop knitted sweaters can be divided into two-in-one and three-in-one. Two of these components include PTT/cotton and PTT/bamboo, and three components include PTT/wool/tencel, PTT/wool/modal and PTT/moisture wicking fiber/tencel.
The purpose of blending PTT with natural fibers is to impart the characteristics of natural fibers to the yarns and fabrics, while improving the defects of PTT in moisture absorption and antistatic, blending with wool, and avoiding yellowing of fabrics; blending with natural fibers. On the basis of this, adding some new fibers such as Tencel can improve the functionality of yarns and fabrics. For example, the new PTT fiber has good elasticity and can improve the shape retention of the knitted sweater; the use of Tencel fiber can make the sweater have better softness and drapability, but without losing the body, moisture absorption and permeability, even after repeated washing, Sunlight does not lose many health care functions, it is not easy to pilling; Modal fiber can significantly enhance the thermal and moisture comfort of the fabric, improve the gloss and feel of the fabric; moisture wicking polyester fiber can be used to make it wet. Dry, keep the skin dry and comfortable; bamboo fiber can make the fabric more breathable, but also has antibacterial effect.
The above materials were used to weave two-sided and double-sided tissues on a 14G hand flat knitting machine, and the performance test was compared after finishing. The finishing process is as follows:
(1) Washing agent Shande net 0.5%, bath ratio 1:30, washing at 60 ° C for 10 minutes; (2) rinsing with warm water of 40 ~ 50 ° C 2 times, then wash with water; (3) softener WA LIQ 2ml / L, acetic acid 0.5 ml / L, bath ratio 1:30, soaked at 50 ° C for 20 minutes; (4) dehydrated and dried.
PTT staple fiber fabrics are soft and smooth, and the amount of additives can be reduced accordingly. The finished fabric is neat and tidy, and the hand feels soft and full.
After performance testing, the knitted sweater fabric developed has the following characteristics:
The fabric has suitable elasticity in both the longitudinal and transverse directions and has excellent elastic recovery properties. The fabric has a slight pilling phenomenon, but because the strength of the PTT blended yarn is relatively low, the hair ball is easy to fall off, and in general, the pilling resistance is better. Due to the excellent elasticity of the PTT fiber itself, the fabric has better wrinkle resistance. Since the blended yarn contains natural fibers and some functional fibers, the thermal and moisture comfort of the fabric is significantly improved. The fabric has a novel drape. The fabric is soft and light, with a cashmere-like feel. Due to the addition of PTT elastic fibers to the blended yarn, the dimensional stability of the fabric is significantly improved.
We can see that the development of knitted sweaters with PTT spun yarn has many unparalleled advantages. It is believed that PTT will have a place in the knitted sweater market with its excellent performance in the near future.
