What is the trifilament in cotton yarn? Why do cotton yarns have three wires? At present, in the process of cotton yarn sales and use, the problem of Sansi has become a headache for everyone. 90% of the three filaments in the cotton yarn are determined by cotton, and it is determined by the cotton picking method that determines the three filaments in the cotton. The machine picking cotton can be used for three strands, while the manual picking cotton is cotton. Pockets, hair and some impurities brought in by people, resulting in more than three filaments in cotton.
The "three wire" mixed into the raw cotton is easily broken into numerous small fibers, which is difficult to remove in textile processing, affecting the quality of cotton yarn and cloth, and is very harmful. When spinning, the fiber breaks easily break the cotton yarn and reduces the production efficiency. When weaving, it affects the quality of the fabric. When dyeing, the fibers and fabrics are unevenly dyed, which affects the appearance.
That is, you need to know the origin of cotton, because the three silks in different places are different.
1. Three-strand cotton:
1) Australian cotton: machine picking, basically eliminate the problem of three wires.
2) US cotton, Brazilian cotton: machine picking, but the situation of the three-strand is slightly inferior to Australian cotton.
3) Xinjiang cotton: machine picking and hand picking, that is, some cotton can be wrapped in three wires. The cotton that can be wrapped in three threads is the machine for cotton mining.
4) West Africa: Kaylong hand picking, consistency uniformity is better, three filaments less, the main features are yellowish and gray color, the shortcoming is the fineness of the length of the general length, can be spinning 40-60 yarn.
2, do not include three-silk cotton: Indian cotton, West African cotton, Pakistani cotton, they are all artificially picked cotton, although the spinning is equipped with a foreign fiber picking device, but fundamentally did not solve the three-wire problem, so it is not included Three silk.
Second, understand the yarn:
Although some countries and regions also do spinning exports, they do not produce cotton, they all rely on imported cotton to do, and the number of three filaments depends on the origin of cotton.
1) Indonesian yarn: mainly using West African cotton and Indian cotton, it does not contain three silk.
2) Vietnamese yarn: mainly use American cotton, West African cotton, Indian cotton, and understand the source of cotton when using Vietnamese yarn.
3) Taiwan yarn: air spinning and cotton are mainly raw cotton and green dust, silk, cotton, and scrap. Therefore, whether air spinning can cover three filaments depends not only on the origin of cotton, but also on the use of cotton. The scrap of cotton from that place. Such as: Taiwan's air spinning, some yarns can be wrapped in three filaments, and some yarns are only three filaments but not included.
In addition, the air-spinning cotton is mainly made of raw cotton and scraps (falling cotton + silk), so whether the air spinning can be wrapped in three filaments, not only depends on the origin of the cotton, but also depends on the cotton of the producing area. Scrap. For example, the air spinning in Taiwan, the raw cotton is American cotton, but because the source of the scrap is different, some yarns can be wrapped in three filaments, and some yarns are only three filaments but not included.
