Polyester viscose yarn manufacturing method

Polyester viscose yarn is an important raw material widely used in the field of chemical production, with excellent physical properties and chemical stability. This article will introduce the manufacturing method of polyester viscose yarn in detail, including raw material selection, preparation process, post-treatment and so on.

1. raw material selection

polyester viscose yarn is the main raw material of polyester and viscose fiber. Polyester is a synthetic fiber with high strength, elasticity and abrasion resistance, while viscose is a regenerated cellulose fiber with good moisture absorption, air permeability and dyeing properties. According to the use and requirements of the product, the two raw materials can be mixed in a certain proportion.

2. preparation process

1. Ingredients
According to a predetermined ratio, the polyester and viscose fibers are well configured to ensure the accuracy and uniformity of the raw materials.
2. Blending
The configured raw materials are blended by the blending machine to make the polyester and viscose fibers fully and evenly mixed together.
3. Spinning
The blended fibers are spun through a spinning machine to form polyester viscose yarn. In the spinning process, it is necessary to control the yarn twist, tension and other parameters to ensure the quality and performance of the yarn.

3. post-treatment

1. Heat-setting
polyester viscose yarn will produce internal stress during the preparation process, which needs to be eliminated by heat-setting treatment. Heat setting treatment can effectively improve the dimensional stability of polyester viscose yarn.
2. Washing
Polyester viscose yarn will leave some oil and impurities in the preparation process, which need to be removed by washing treatment. Washing treatment can ensure the cleanliness and color of polyester viscose yarn.

4. quality control

In the manufacturing process of polyester viscose yarn, it is necessary to strictly control the quality of each link to ensure that the performance and quality of the final product meet the requirements. Quality control includes raw material testing, process monitoring, finished product inspection and other aspects.

In short, the manufacturing method of polyester viscose yarn needs to fully consider factors such as raw material selection, preparation process, post-processing and quality control to ensure the performance and quality of the final product. At the same time, it is also necessary to continuously optimize manufacturing solutions according to specific production conditions and market demand to improve production efficiency and economic benefits.

in the field of chemical production in the future, polyester viscose yarn as an important raw material, its manufacturing method will continue to receive attention and research. With the continuous progress and application of science and technology, the manufacturing method of polyester viscose yarn will be more efficient, environmentally friendly and intelligent. At the same time, the application field of polyester viscose yarn will continue to expand, injecting new vitality into the development of chemical production field.
