preparation example Construction

[0028] The embodiment of the present invention firstly carries out the preparation of the fiber skin layer material:

[0029] In parts by mass, 84-89 parts of PA6 slices, 10-13 parts of jade powder, and preferably 1-3 parts of coupling agent are mixed uniformly, and added to a twin-screw machine, melted at a temperature of 230-250 ° C, and the screw The speed can be 100-130r / min. The above nylon material in molten state is extruded through the head of a wire drawing machine, preferably the extrusion temperature is controlled to 210-220°C, and the pressure of the head of the wire drawing machine is 0.2-0.3 MPa. After the nylon yarn is cooled by the cold water tank, it enters the pelletizer and is cut into pellets. The pelletizer speed can be 140r / min, and the particle size is generally 3-6mm. The mass parts and process parameters within the scope of the present application can meet the production requirements and have little influence on the final fiber properties.

Abstract

The invention provides a preparation process and fabric of a cool-feeling and quick-drying composite fiber. The process includes the following steps: extruding a fiber skin material into a first melt by extruding a fiber skin layer at a high temperature and low temperature; extruding a fiber core layer into a first melt; The material is melted and extruded into the second melt according to the mode of low-temperature melting and high-temperature extrusion; the fiber skin layer material includes 84-89 mass parts of PA6 and 10-13 mass parts of jade powder; the fiber core layer material is a poly Propylene; the first melt and the second melt are extruded through a skin-core composite spinning assembly, and drawn to obtain a cool-feeling and quick-drying composite fiber. The skin-core composite fiber prepared by the invention not only maintains the cool feeling characteristic of the nylon material, but also improves the quick-drying performance of the nylon material and improves the wearing comfort. The contact cooling coefficient Q-max value of the fabric woven from this fiber is above 0.20, and has good quick-drying performance and is comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a preparation process and fabric of a cool-feeling and quick-drying composite fiber. Background technique [0002] Nylon is a term for polyamide fibers (nylon), which can be made into long fibers, staple fibers, etc. Nylon is the trade name of polyamide (PA) fiber, also known as nylon (Nylon); there are many varieties of PA, such as PA6, PA66 and so on. Nylon material is widely used in clothing. It has excellent wear resistance and heat resistance (the melting point of nylon 6 is 220 °C, and the melting point of nylon 66 is 260 °C), and it has a waxy feel and good quality. [0003] Especially in the summer clothing category, nylon T-shirts have an excellent cooling experience. Compared with polyester materials, contact nylon fabrics bring a cool feeling. Part of the reason is that the amino group contained in the molecular structure of polyamide fibers is a type of hy...
