Process for producing nylon fibre under low temperature

Abstract

The invention discloses a method for producing nylon fiber under low temperature, which includes adding a rare-earth metal compound before or when the nylon is in melted state and conducting the spinning of the molten mass under low temperature between 160 DEG C and 250 DEG C. The energy consumption and cost of the method are low with more convenient and safer industrial operations.

Description

technical field

[0001] The invention relates to the technical field of textiles, in particular to a method for producing nylon fibers at low temperature. Background technique

[0002] Generally speaking, the polymer materials that can be spun include nylon (polyamide), polypropylene (polypropylene), polyester (polyethylene terephthalate) and acrylic (polyacrylonitrile). These materials can be spun to form filaments for use in the textile industry. Melt spinning is a commonly used spinning method, and fiber filaments suitable for spinning can be obtained by melt spinning. Generally, fiber filaments obtained by the melt spinning method can reach a fineness degree (fineness) of several deniers. The products obtained by weaving and weaving with such fiber filaments, such as clothing fabrics, have many advantages, so the market application space is broad.

[0003] Nylon fiber fabric has the characteristics of sweat absorption, light weight, good toughness, good resilience, aci...
