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

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

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

Knitted fabrics or jeans made of core-spun yarn can be stretched freely when worn and fit comfortably. The main purpose of industrial weaving yarns is to strengthen cotton canvas, maintain the water repellency of cotton fibers when they are swelled by water, and use polyester fibers to be wet when exposed to rain. High tensile, tear and shrink resistance, the woven fabric is easy to dye and finish, comfortable to wear, easy to wash, bright in color and elegant in appearance. Using the different

1. Soft fabrics Soft fabrics are generally light and thin, with good drapability, smooth modeling lines, and natural stretch of clothing outlines. Soft fabrics mainly include knitted fabrics, silk fabrics, soft and light linen fabrics, etc. Soft knitted fabrics are often used in clothing design. The straight and concise shape is used to reflect the graceful curves of the human body; silk, hemp yarn and other fabrics are mostly loose folds, showing the elegant feeling of the fabric lines.2. Cool

With the development of the economy, there are many polyester yarn manufacturers on the market. These companies have their own advantages, but customers must choose according to their actual situation when choosing. So do you know which is the best color polyester yarn manufacturer? What are its advantages? I will tell you about these questions in the following. Which is the best polyester yarn manufacturer? In the face of this problem, we can't blindly tell everyone which one is doing bet
