Abstract

The invention provides a superfine flexible fiber material and a preparation method thereof and belongs to the field of fiber materials. The superfine flexible fiber material comprises the following raw materials in parts by weight: 60-80 parts of polyphenylene sulfide slices, 100-120 parts of alpha-naphthalene chloride, 2-5 parts of pectin, 50-80 parts of deionized water, 5-8 parts of an antioxidant, 2-5 parts of a dispersing agent, 9-24 parts of polylactic acid, 3-8 parts of polytrimethylene carbonate, 3-8 parts of polydioxanone and 3-8 parts of polycaprolactone. The fiber material has highflexibility, and is difficult to age, long in service life, green and environmentally friendly. The preparation method of the superfine flexible fiber material is simple, and the prepared superfine flexible fiber material is better in property.

Description

technical field [0001] The invention belongs to the field of fiber materials, and in particular relates to an ultrafine denier flexible fiber material and a preparation method. Background technique [0002] In my country, the fiber of 0.9-1.4dtex is generally called fine denier; the fiber of 0.55-1.1dtex is micro-denier; and the fiber below 0.55dtex is ultra-fine denier. Ultra-fine denier silk can be woven into high-grade textiles with soft hand feeling and comfortable wearing, which has high economic value. Therefore, the development of fine-denier fiber and ultra-fine-denier fiber manufacturing technology is a high-tech that all countries have paid attention to in recent years. [0003] Polyphenylene sulfide fiber has good heat resistance and is mainly used as a high-temperature filter fabric, which can withstand temperatures up to 190°C. The fiber also has excellent resistance to chemical agents and hydrolysis, as well as flame retardant properties. It can be used as f...
