Abstract

The invention discloses a bio-based polyester non-woven fabric and a preparation method thereof. The bio-based polyester non-woven fabric is prepared from bio-based polyester filaments through a spunlace process. The bio-based polyester filament is prepared from the following raw material of, in parts by weight, 80-88 parts of bio-based succinic acid-pentanediol ester copolyester, 12-16 parts of bio-based polypentamethylene adipate diamine, 6-9 parts of a thermoplastic elastomer, 1.5-2.5 parts of carboxylated carbon nanotubes, 2-3.5 parts of quartz fibers, 3-5 parts of calcium carbonate, 0.8 to 1.2 parts of cerium dioxide and 5 to 7 parts of maleic anhydride grafted polypropylene. The bio-based polyester non-woven fabric is high in bursting strength and breaking strength which are very close to those of common PET non-woven fabric, good in mechanical property, durable, good in biodegradability, environmentally friendly, healthy and high in use comfort; and the comprehensive mechanicalperformance is good, the comprehensive use performance is good, and the market application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a bio-based polyester non-woven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. [0003] Because it is a fabric that does not need spinning and weaving, it is just oriented or random arrangement of short textile fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. [0004] It is not interwoven and braided by one yarn, but the fibers are directly bonded together through physical methods, so when you get the sticky scale in your clothes, you wi...
