Abstract

The invention provides non-woven fabric. The non-woven fabric is prepared from the following components: 60-80 parts of polylactic acid, 20-30 parts of polyurethane, 10-20 parts of polyimide, 30-45 parts of chitosan, 5-10 parts of a flow modifier, 1-3 parts of alkyl sodium solfonate serving as an anti-static agent, 2-4 parts of epsilon-polylysine serving as an antibacterial agent and 3-6 parts of decabromodiphenyl serving as a flame retardant. The non-woven fabric is prepared with an electrostatic spinning method; four easy-to-degrade raw materials including polylactic acid, polyurethane, polyimide and chitosan are used for preparing a spinning solution, and the prepared non-woven fabric is bio-degradable and very environment-friendly; additionally, the non-woven fabric integrates functions of an antibacterial property, radiation protection, water repellency, static resistance and the like, can basically meet various medical demands and has a wide application range.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, and in particular relates to a non-woven fabric material and a preparation method thereof. Background technique [0002] Non-woven fabric (non-woven fabric) is a kind of fabric formed without spinning and weaving. It just orients or randomly arranges short textile fibers or filaments to form a web structure, and then uses mechanical, thermal bonding or chemical bonding. Reinforced by other methods. To put it simply: it is not interwoven and knit together by yarns one by one, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes , you will find that it is impossible to extract the thread ends one by one. Nonwovens have broken through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide application, and multiple sources of raw materials. They are w...
