Polyester yarn manufacturers tell you that different classification methods produce different names：　　1) Differences in the use of raw materials: pure cotton silk, pure cotton fiber silk, cotton blended yarn, model blended yarn, etc.　　2) Different spinning methods: ring spinning, air spinning, electrostatic spinning, etc.　　3) Different spinning techniques: cotton yarn combing, combing yarn, peach silk thread, etc.　　4) Differences in the direction of kink: smooth kink (S kink) 4. Backhan

　　High elastic wire: High elastic wire or high elastic deformation wire has high elasticity and general expansion.It is mainly used for spandex fabrics, mainly polyester high-carbon silk.　　Low elastic wire: Low elastic wire or deformed elastic wire has appropriate stretchability and expansion.It is mostly used for knitted fabrics, and polyester has more low elastic silk.　　Expansion yarn 3360 expansion yarn has low elasticity and high expansion.It is mainly used as fabrics with good expansi

We often meet some customers who require that the samples provided be consistent with the supplied samples. We often solve this problem by using regular grey cloth. Due to many technical elements involved in the customization process, more professional business personnel are required to communicate with customers more effectively. To fully understand the needs of customers and express them more clearly with front-line technicians. Through clear expression, professionals can more effectively deve

For the production of characteristic yarn products, fiber composition distribution is one of the key technologies of zui. The combination and distribution technology of fiber components is divided into the technology that can realize the quasi uniform distribution of heterochromatic fiber components in the yarn according to the established mixing ratio requirements (referred to as fine mixing technology for short) and the technology that can realize the combination and distribution of some fiber

For the production of characteristic yarn products, fiber composition distribution is one of the key technologies of Zui. The fiber component combination and distribution technology can be divided into the technology that can realize the quasi uniform distribution of heterochromatic fiber components in the yarn according to the specified mixing ratio (referred to as fine mixing technology) and the technology that can realize the combination and distribution of some fiber components and the main

Knitting requires higher yarn evenness (i.e. yarn thickness uniformity), good softness, certain strength, extensibility and twist (yarn twist is relatively low). In the process of forming knitted fabrics on the knitting machine, the yarn will be subjected to complex mechanical effects, such as stretching, bending, twisting and friction. In order to ensure normal production and product quality, knitting yarn shall meet the following requirements:oneThe yarn shall have certain strength and extensi

Yarn twist direction refers to the twist direction of yarn twist back. If the fiber is inclined from the upper left to the lower right after twisting, it is S twist. If the fiber is inclined from the upper right to the lower left after twisting, it is Z twist. The twist direction of yarn has an influence on the surface gloss, the clarity of fabric grain, and the feel and thickness of fabric. When the matching of warp and weft yarns with different twist directions is adopted, as shown in Figure 2

What is mercerizationCotton products (yarn, fabric) are treated with concentrated caustic soda solution under tension, and then washed away under tension.1、 Purpose of mercerization1. The luster and brightness are improved after mercerization;2. The adsorption capacity and chemical reaction capacity are enhanced, and the dye yield is improved;3. Shrinkage, dimensional stability, and improved fabric flatness;4. The mechanical properties such as strength and extensibility have changed.2、 Merceri

There are many kinds of yarns with different properties. Generally, it can be classified according to the raw materials used in yarn, yarn thickness, spinning method, spinning system, yarn structure and yarn use.According to the spinning process: combed yarn, combed yarn.According to the fiber length of the yarn: filament yarn, short fiber yarn, filament short fiber composite yarn.According to the fiber types of yarn: pure spinning, blended yarn, cross twist yarn, blended yarn.According to the y
