preparation example Construction

[0028] The embodiment of the present invention first carries out the preparation of fiber cortex material:

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

Abstract

The invention provides a reparation process of cool quick-drying composite fibers and fabric. The preparation process of the cool quick-drying composite fibers comprises the following steps: melting and extruding a fiber skin layer material into first melt according to a high-temperature melting and low-temperature extrusion mode; melting and extruding a fiber core layer material into second melt according to a low-temperature melting and high-temperature extruding mode; wherein the fiber skin layer material comprises 84-89 parts by weight of PA6 and 10-13 parts by weight of jade powder; and the fiber core layer material is polypropylene; and carrying out extrusion molding on the first melt and the second melt through a skin-core composite spinning assembly, and drafting is conducted to obtain the cool quick-drying composite fibers. The skin-core composite fibers prepared by the invention not only maintain the cool feeling characteristic of a 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 by the fibers is 0.20 or above, and the fabric 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 quick-drying composite fiber. Background technique [0002] Nylon is a term for polyamide fiber (nylon), which can be made into long fibers, short 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 and PA66. 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). [0003] Especially in the summer clothing category, nylon T-shirts have an excellent cooling experience. Compared with polyester materials, nylon fabrics bring a cooler feeling. Part of the reason is that the amino groups contained in the molecular structure of polyamide fibers are a type of hydrophilic group, and water has a larger specific heat capaci...
