Sour fiber.
Background technique
With the development of Science & Society, chemistry, macromolecule and nanotechnology are rapidly developed, however with traditional
The chemical fibre of chemical mode production causes very big burden to environment and resource, therefore for the sustainable development of society,
Protection environment and the concern that people are increasingly subject to using regenerated resources.In field of textiles, people do not require nothing more than taking to fiber
Good, bright color is novel, also requires environmentally protective, and pro-skin is comfortable.
Acid fiber by polylactic, also known as zein fiber, PLA fiber, be using the amylofermentations such as corn, wheat convert lactic acid as
Raw material synthesizes lactide by monomer lactic acid Cyclodimerization, and ring-opening polymerisation synthesizes lactide again, can also be melted by direct polycondensation of lactic acid
Melt spinning and forms fiber.Acid fiber by polylactic because not using the raw materials such as petrochemical industry completely, and less energy consumption when production and processing, pollution is few,
And carbon monoxide toxic gas is not generated when biodegrade and burning, it is one of green fiber most with prospects.
Silk is a kind of native protein, has excellent mechanicalness and skin affinity, usually referred to as fiber queen, and
The processing performance of silk is good, and the diversified forms such as fiber, powder, gel, solution, film can be made into according to different purposes, makees
The functionality of composite material is improved for substrate or additive.
Zein fibers currently on the market are that protein is extracted from animals and plants as raw material, total with acid fiber by polylactic
Spinning solution, the fiber most obtained afterwards through techniques such as spinning, solidification, drawing-off, drying, curling, sizings are formed after mixed, crosslinking, grafting.
The machinability and mechanical strength of this fiber material are weaker, and the practicability is poor.
Chinese document (" research of fibroin polylactic acid blend fibre property ", Gu Wei, University Of Suzhou's Master's thesis, in May, 2006
15 days) disclosed in fibroin polylactic acid blend fiber be to be dissolved in HFIP solvent with dry particles of polylactic acid after fibroin forms a film, warp
Spinning solution is obtained after oscillation dissolution, filtering, vacuum defoaming, it is fine to obtain fibroin polylactic acid blend through wet spinning, heat setting, setting
Dimension.This method preparation fibroin polylactic acid blend fiber with regenerated fibroin fiber compared with intensity and elongation it is small, in blended fiber with
The raising of polylactic acid specific gravity, breaking strength and extension at break taper off trend.Chinese patent CN 104530670A (publication date
