Abstract

The invention relates to a nylon fiber with low surface frictional coefficient and improved hydrophobicity and a preparation method thereof. The preparation method comprises mixing modified nylon masterbatch and nylon chips in a mass ratio of (0.5-5):(95-99.5), and performing melt spinning to obtain the nylon fiber with low surface frictional coefficient, wherein the modified nylon masterbatch ismainly composed of, by weight, 37-88.8% of nylon, 10-60% of PDMS (polydimethylsiloxane) and 0.2-3% of POSS with amino side chains and is made by adding the materials proportionally into a mixer, mixing well, transferring to a twin-screw extruder and dicing. The prepared nylon fiber with low surface frictional coefficient and improved hydrophobicity has both dynamic frictional coefficient and stationary frictional coefficient of less than 0.3, has an angle of contact with water being greater than 71 DEG, has good durability, spinnability and good mechanical properties, and has a good application prospect.

Description

technical field

[0001] The invention belongs to the technical field of fiber manufacturing, and relates to a nylon fiber with low surface friction coefficient and improved hydrophobicity and a preparation method thereof. Background technique

[0002] Nylon fiber is a kind of synthetic fiber connected by amide bonds. It has a series of excellent properties, such as high strength, good resilience, excellent wear resistance and chemical corrosion resistance, and strong impact resistance. It is used in clothing, decoration and Industry and other fields have been widely used. With the continuous differentiation of application fields, people often put forward different requirements for specific applications. In order to meet the requirements of water repellency and antifouling of clothing fibers, especially outdoor sports series clothing, and to improve the unique appearance and feel of microfiber fabrics, it is necessary to Nylon fiber is modified to reduce the friction coeffici...
