Spinning technology

edit

There are two ways to solve the problem of yarn strength. One is to use more advanced spinning technology without changing the raw materials to spin the yarn suitable for easy care fabrics, such as compact ring spinning technology.

The second method is to adjust the raw materials and change the yarn structure. Through the combination of the original natural fiber and the fiber with excellent performance meeting the requirements of easy care, the two can be combined through certain spinning methods to get the yarn with ideal effect, mainly including blended yarn and composite yarn, which are introduced below.

1. blended yarn

In the mixed spinning of two or more kinds of fibers, the methods of bulk fiber mixing and sliver mixing are mainly used. The strength of the whole yarn is increased by the original fiber material and other fibers with high strength and high modulus. This kind of composite yarn includes traditional polyester / cotton, polyester / viscose, polyester / wool, etc., as well as polyester / cotton / Tencel fiber, polyester / cotton / cashmere, etc.

2. composite yarn

Two kinds of different fibers are interwoven with single yarn or filament, which are similar to strand structure. They can be spun on modified spinning frame or hollow spindle. There are mainly siro spinning, sirofil spinning, wrapped spinning, core spinning and so on.
