Abstract

The invention discloses a synthetic fiber with strong restorative property and a preparation method thereof, and relates to the field of fiber technology. In the present invention, nickel nitrate hexahydrate and cobalt chloride hexahydrate are dispersed in ultrapure water, and glycerin and methanol are added, and after heating and reacting, a layered double metal hydroxide is prepared, and the layered double metal hydroxide is placed in the Acrylic acid is inserted under acidic conditions to prepare a modified layered double metal hydroxide blank, and then the modified layered double metal hydroxide blank is mixed with polyethylene glycol methacrylate in a pretreated phthalic anhydride containing The modified hydroxide is prepared under the action of photoinitiator in the branched polyethyleneimine solution, and finally, the modified hydroxide is mixed with polypropylene, and epoxy soybean oil, compatibilizer and initiator are added, and melted After extrusion, the masterbatch is obtained, and after the masterbatch is melt-spun, the synthetic fiber with strong recovery is obtained. The synthetic fiber with strong restorative property prepared by the invention has excellent mechanical properties and good restorative property.

Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a synthetic fiber with strong recovery and a preparation method thereof. Background technique [0002] Polypropylene is a synthetic fiber isotactic polypropylene fiber made from propylene, a by-product of petroleum refining. [0003] The varieties of polypropylene include filaments (including undeformed filaments and bulky deformed filaments), short fibers, bristles, split fibers, hollow fibers, shaped fibers, various composite fibers and non-woven fabrics. The main purpose is to make carpets (including carpet base cloth and suede), decorative cloth, furniture cloth, various ropes, strips, fishing nets, linoleum, building reinforcement materials, packaging materials and industrial cloth, such as filter cloth, bag cloth Wait. In addition, it is widely used in clothing. It can be blended with various fibers to make different types of blended fabrics. After knitting, it can be made...
