Abstract

The invention discloses polylactate polyamide ultrafine composite fiber. The polylactate polyamide ultrafine composite fiber comprises the following components in parts by weight: 50-60 parts of ultrafine polyamide, 40-50 parts of polylactic acid fiber, ultrafine polyamide is taken as a core wire, the core wire is coated with polylactic acid fiber; the ultrafine polyamide comprises 85-95 parts of chinlon-6 chips, 5-7 parts of active carbon and 6-10 parts of nano silica; polylactic acid fiber comprises 100 parts of polylactic acid, 5-10 parts of a maleic anhydride grafting compatilizer, 1-2 parts of tert-butyl peroxybenzoate, 5-8 parts of citric acid, 10-16 parts of tert-butyl alcohol, 2-6 parts of zinc oxide, 2-5 parts of vinyl polydimethyl silane, and 0.2-0.5 parts of phosphate. The prepared composite fiber has the characteristics of comfortable hand feeling, good elasticity, degradable performance, egradable performance, and certain antibacterial property, by tight coating of core wire and polylactic acid fiber, the composite fiber has the advantages of high intensity and difficult fracture, and a preparation method is simple and feasible.

Description

technical field [0001] The invention relates to a composite fiber, in particular to a polylactic acid nylon superfine composite fiber. Background technique [0002] With the improvement of people's living standards, the requirements for textiles are getting higher and higher. Currently, nylon fibers on the market have problems such as rough hand feeling, poor flexibility, poor air permeability, poor water absorption, and easy pilling. Subsequently, ultra-fine nylon fiber began to appear on the market, which is soft to the touch and comfortable to wear. However, the quality of the ultra-fine nylon fiber on the market is not high, it is not easy to dye, low in grade, high in defective rate, and poor in economic benefits. On the other hand, polylactic acid is compounded in units of lactic acid, a product of microbial fermentation. Polylactic acid products can be completely decomposed into carbon dioxide and water after being discarded, and will not pollute the environment, so ...
