The manufacturing method
of polyester-brocade composite wire
1. Introduction
polyester-brocade composite wire is an important raw material widely used in the field of chemical production. Because of its unique physical and chemical properties, it is widely used in textiles, plastics, coatings and other fields. This paper will introduce the manufacturing method of polyester-brocade composite wire in detail, including raw material selection, production process, post-treatment and other links.
2. raw material selection
manufacture of polyester composite yarn of the primary task is to choose the right raw materials. Polyester and nylon are two common synthetic fibers with good mechanical properties, thermal stability and chemical stability. When selecting raw materials, the molecular weight, molecular weight distribution, melting point, crystallinity and other factors of the fiber should be considered to ensure the properties and performance of the final product.
3. production process
polyester-brocade composite yarn production process mainly includes the following steps:
1. melt extrusion: polyester and nylon raw materials were added to the melt extruder, heating and melting, through the screw extrusion to form a melt.
2. Composite spinning: the melt of polyester and nylon is compounded by the composite spinning head to form primary fibers.
3. Stretching: The nascent fiber is stretched to increase its strength and elasticity.
4. Heat setting: Through heat setting treatment, the fiber structure is stable and its dimensional stability is improved.
4. post-treatment
In order to further improve the properties and performance of polyester-brocade composite yarn, some post-treatment processes are needed:
1. Drafting: Through drawing treatment, the strength and elongation of the fiber are further improved.
2. Crimp: make the fiber have a certain degree of crimp to improve its bulkiness and elasticity.
3. Cut: cut long fibers into short fibers of a certain length to facilitate subsequent processing and use.
5. Quality Control
In the manufacturing process, strict quality control is required for all aspects, including the quality of raw materials, the monitoring of process parameters, and the quality inspection of products. Only by ensuring the quality of each link can the quality and performance of polyester-brocade composite yarn be finally guaranteed.
of environmental protection and sustainability in
6. With the increasing concern of the society about environmental protection and sustainability, the manufacture of polyester/polyamide composite yarn also needs to consider environmental protection and sustainability. In the selection of raw materials, priority should be given to renewable or recyclable materials; in the production process, energy consumption and waste emissions should be reduced; in the design and use of products, product life cycle and recyclability should be considered.
7. market and application
As an important raw material for chemical production,
polyester-brocade composite wire has been widely used in various fields. With the development of science and technology and the change of market demand, the application field of polyester-brocade composite wire is also expanding. Therefore, understanding and mastering the manufacturing method of polyester-brocade composite yarn is of great significance for improving product quality, reducing costs and expanding market applications.
8. conclusion The manufacturing method of
polyester-brocade composite yarn involves the selection of raw materials, production process, post-treatment and other links, each of which has an important impact on the quality and performance of the final product. Therefore, it is necessary to fully consider the factors of each link in the manufacturing process to ensure the quality and performance of the final product. At the same time, with the improvement of environmental protection and sustainability requirements, the manufacture of polyester-brocade composite yarn also needs to pay more attention to environmental protection and sustainability.
