Description
Technical field
The present invention relates to a kind of novel polylactic acid fiber fabric, belong to field of textiles.
Background technology
The raw materials for production lactic acid of acid fiber by polylactic (PLA) is obtained from cornstarch, so also this fiber is called zein fiber, can garden beet or cereal etc. make through glucose fermentation, to reduce the cost of preparation lactic acid polymerizes body.The PLA of high molecular can be obtained by the chemical polymerization of lactic acid Cyclodimerization thing or the direct polymerization of lactic acid.Be the goods that raw material obtains with PLA, there is good biocompatibility and Bioabsorbable, and biocidal property, anti-flammability, and in biodegradable thermoplastic polymer material, PLA has best heat resistance.
Along with the exploitation mechanism of acid fiber by polylactic and being on the increase of enterprise both at home and abroad, the application of acid fiber by polylactic in textile industry will be more and more extensive.Take PLA as the goods that raw material obtains, there is good biocompatibility and Bioabsorbable, and the good performance such as biological degradability, water imbibition, biocidal property, anti-flammability, but easily shrink under wet, thermal environment, cohere, affect processing and the application of acid fiber by polylactic.
Prior art has disclosed the method for multiple modified polylactic acid fiber, as Chinese patent application 201210096514.2 discloses a kind of preparation method of hydrolytic-resistant modified polylactic acid fiber, comprise: by weight by PLA 70 ~ 98.9 parts, low molecular weight polyester 1 ~ 30 part, multi-functional polycarbodiimide 0.1 ~ 5.0 part mixing, carry out melt blending granulation after mixing and obtain master batch, obtained master batch is obtained undrawn yarn by melt spinning, winding after vacuumize, finally carry out drawing-off, obtain modified acid fiber by polylactic.The modified polylactic acid fiber of this invention has excellent feel and flexibility, and can realize low temperature dyeing, and the dye-uptake of high-temp dyeing is higher, because resistant to hydrolysis performance is good, and the problem that when can avoid high-temperature process, mechanical property is deteriorated.But due to adding of cross-linking type polycarbodiimide, a small amount of irritative gas can be produced in spinning engineering certain injury is caused to human body.
The PLA of different optical structure mixes by somebody according to a certain percentage, finds, under certain component and ratio, to have an unexpected effect.And the research to blended recipe ingredient, be mainly the cellulose to adding, other components, and consider between compatibility between component.Also have patent document to find to adopt special-shaped spinneret orifice can improve the Moisture absorption & moisture conductivity of modification PLA fiber at melt spinning, especially pentagon profile spinneret spinning pentagon abnormity PLA fiber effects is especially good.But these technology all do not solve the acid fiber by polylactic not easily upper shortcoming contaminated, and the spinnability of special-shaped PLA fiber can be affected.
The present invention aims to provide a kind of novel polylactic acid fiber fabric.
