Identification of polyester-cotton yarn and polyester-viscose yarn Untwist the two yarns, and then look at the length of the single fiber; whether the polyester cotton yarn is polyester staple fiber or cotton fiber is usually cotton type, the cut length of polyester is 38mm, and cotton contains long-staple cotton. The length is 23mm~45mm. If the…
Identification of cotton yarn and rayon yarn 1. Cotton yarn will not emit sparks when it burns, while rayon yarn will emit sparks, and the burning speed is faster than cotton yarn. 2. Cotton yarn moistened with water, its strength will not decrease, while rayon yarn moistened with water, its strength greatly decreases, and the…
Discrimination of air-jet spinning and vortex spinning The air-jet yarn structure is divided into two parts: the core and the outer fiber. The yarn core is parallel and twisted. The structure is tight. The outer fiber is loose and irregularly wound outside the yarn core. Therefore, the air-jet yarn has a looser structure and a…

1. The calculation formulas commonly used in textiles are divided into two types: fixed-length calculation formulas and fixed-weight calculation formulas. (1) Denier (D) = g/L*9000 where g is the weight of the silk thread (grams), and L is the length of the silk thread (meters) (2), tex (number) [tex(H)]: tex=g/L*1000 where g is the weight…
advantage: 1. Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal conditions, the fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so it touches human skin and makes people feel soft Without being stiff. If the humidity of the cotton cloth increases and the surrounding temperature is higher, all the…
