The longer fibers tend to the axis of the yarn more, while the shorter fibers tend to the outer layer of the yarn more.

The fineness tends to the axis of the yarn, and the fineness tends to the outer layer of the yarn.

The fibers with small initial modulus are more located in the outer layer, while the fibers with large initial modulus are more located in the inner layer.

Reasonable selection of different properties of the fiber, can be spun into different styles of yarn, to adapt to the use of different fabrics or improve the performance.

Because the length, fineness and cross section shape of the chemical fiber can be arbitrarily selected, it is advisable to choose the chemical fiber with slightly thicker and shorter length blended with cotton to increase the wool shape on the surface of the yarn.

Underwear fabric should be selected with a slightly fine fiber and a slightly longer length of chemical fiber, so that cotton fiber in the outer layer of the yarn, in order to improve the moisture absorption performance and wearing comfort.

Self-end spinning, including air spinning, electrostatic spinning, eddy spinning and other spun yarns, due to less fiber transfer to the inside, the core of the yarn compared with the outer layer, tight and loose, the structure is looser, fiber elongation is poor, fiber binding force is poor, low yarn strength, but good dyeing and wear resistance.

The yarn spun by self spinning yarn is also called self spinning yarn, which is made of rolling roll to produce periodical positive and negative false weight on the thread, and appears periodical non spinning point on the yarn, so the strength is low, and then woven after the thread is generally combined.

 

Filament yarn is made of filament (such as natural silk, synthetic silk, or rayon) bound together;

Mainly polyester filament, viscose filament, nylon filament and so on.

 

Fancy yarns are mainly characterized by changes in the appearance or color of the yarn.

There are mainly wrapped wrapped, wrapped core, bamboo, big belly, color point, wave, plait, towel, circle, knot, feather, toothbrush, centipede, belt, paragraph dye, chenille and so on.
