Clothing material knowledge - Characteristics of different yarns

The handle and characteristics of textile products are mainly determined by hairiness. From the production test, it can be clearly seen that the hairiness of length less than 2mm has little effect on the process of production and the appearance quality of the fabric. On the contrary, the fabric has a natural soft feel. However, hairiness over 3mm or more is a potential factor affecting yarn quality.

Different yarn twisting processes produce different yarn structures, and also produce different product characteristics.

1 strength

The strength of the yarn depends on the cohesion and friction between the fibers. If the form and arrangement of fiber, there is a circle, bending, folding, winding fiber, equivalent to short fiber length, weakened the contact degree of fiber, so easy to slip between fibers, reduce yarn strength.

According to the test, if the strength of the ring yarn is 1, then the strength of other kinds of yarn is: rotor yarn 0.8 to 0.9, jet yarn 0.6 to 0.7, vortex yarn 0.8, compact spinning power is highest 1.15.

2 hairiness

The handle and characteristics of textile products are mainly determined by hairiness. From the production test, it can be clearly seen that the hairiness of length less than 2mm has little effect on the process of production and the appearance quality of the fabric. On the contrary, the fabric has a natural soft feel. However, hairiness over 3mm or more is a potential factor affecting yarn quality. Compared with the traditional ring spun yarn, yarn, yarn, close air vortex yarn 1 to Mao Yu 2mm were reduced, and the yarn winding fiber due to low number, twistless yarn core covering less, and there are more short feathers, of course, the number of concrete in the spinning process by adjusting the process parameters to control Mao Yu.

Comparison of yarn hairiness between different spinning methods. Compared with the traditional ring spun yarn, spinning the traditional non harmful hairiness number (>3mm) decreased significantly, the compact yarn reduction of approximately 80%, a decrease of approximately 85% jet spun yarn, vortex spinning is a reduction of 90% or more, so the new yarn has good processing characteristics after. As the new yarn structure makes the surface of yarn more stable, the amount of hairiness after processing is significantly lower than that of traditional yarn. Especially as warp, the size of the slurry can be saved by about 50%, and the loom efficiency and the weaving cost are greatly improved. According to the data, the use of new yarn in the United States every 100m fabric caused by this can be reduced by $2.4, reducing the 72% fly.

3 wear resistance

The wear resistance of the yarn is closely related to the structure of the yarn.

Traditional ring spun yarns are mostly helical in shape. When the friction is repeated, the spiral fibers gradually change into axial fibers. The yarns are easy to twist and break, and they are quickly worn out. Therefore, the wear resistance is poor.

Non traditional spinning has obvious advantages in terms of wear resistance, rotor spun yarn, yarn and yarn by the vortex core and the outer fiber is composed of two parts, winding yarn coated with irregular yarn, not easy to collapse, while the yarn surface friction coefficient, the fabric between yarn and yarn hold together is good, not easy to slip, so the wear resistance increased.

Relative to the ring spinning, compact spinning arrangedregularly straight, yarn structure, fiber is not easy to loose off, the wear resistance of yarn.

4 twisting force

An important characteristic of potential is twist yarn, and determine some properties of fabrics, such as knitting cloth ramp.

The traditional ring spun yarn and compact yarn for real twist spinning, twisting potential, ramps and volume is easy to produce knitted fabrics, and sometimes need to give up.

The yarn structure of rotor yarn, jet yarn and vortex yarn determines its small twisting force. OE Z and S twist and twist potential exist at the same time, the lowest, with a high proportion of the parallel fiber air-jet spun yarn, twisting force is small, also has good processing properties after.

5 anti pilling

Eddy current yarn knitted fabric has good abrasion resistance and high pilling resistance. This is because the middle straight vortex yarn yarn, coated with fiber, fiber orientation, friction coefficient between yarn, fabric yarn and yarn friction is good, not easy to slip, the wear resistance increases, in addition, also with the pilling of yarn hairiness is related. Through the test of pilling test, it can be seen that the vortex yarn fabric is from 4 to 4.5, jet yarn 4, traditional ring yarn 2, rotor yarn 2~3, compact spinning 3~4.
