Abstract

The invention provides a manufacturing method taking polylactic acid fiber as flocking villus. The method comprises that: firstly, polylactic acid slices are subjected to melt spinning, the spinning temperature is between 220 and 240 DEG C, and the spinning speed is between 1,000 and 2,000m/min; then uncrimped tows are obtained through the drawing, wherein the drawing ratio is between 2.5 and 4.0 times, and the drawing rate is between 200 and 400m/min; and the uncrimped tows are cut to obtain polylactic acid flocking villus. The preparation of the polylactic acid flocking villus provides the flocking industry with a brand new villus product having the advantages of environmental protection, high strength, high elastic recovery as well as natural anti-ultraviolet property and flame retardance.

Description

A kind of manufacture method of polylactic acid flocking villus
Technical field
The present invention relates to the synthetic fiber production field in the textile industry, relate in particular to a kind of polylactic acid flocking villus of flocking industry.
Background technology
Now people to clothes except require elegant in appearance, also more and more pursue comfortableness and functional, also to consider its feature of environmental protection.And plant resourceses such as cellulose, starch and vegetable protein, because can biodegradation and circular regeneration, also be a main trend of textile product development.Therefore in recent years, with the plant resources great attention that the research and development of the tencel of raw material has been subjected to countries in the world, acid fiber by polylactic is exactly one of them.Acid fiber by polylactic is to make the synthetic lactic acid polymer of raw material with the lactic acid that human body contains, and human body is perfectly safe.Compare with the conventional fibre material, the maximum characteristics of acid fiber by polylactic (PLA) are exactly environmental protection, have biodegradability.PLA degradation of fiber product is carbon dioxide and water, and these two kinds of products can pass through photosynthesis of plants, become the raw starch of lactic acid, so the PLA fiber can participate in the nature systemic circulation, can not cause environmental issue, is very desirable green fiber.Acid fiber by polylactic also has excellent physical and mechanical properties, as light weight, high-strength, high elasticity reply, natural anti-ultraviolet property and anti-flammability etc., performances such as its hygroscopicity, elastic recovery, UV stable, anti-flammability, feel gloss all are better than terylene, are being widely used aspect medical treatment, knitted fabric, woven fabric and the nonwoven.
Summary of the invention
The purpose of this invention is to provide a kind of is the manufacture method of flocked pile with the acid fiber by polylactic, for the flocking industry provide a kind of have environmental protection, high-strength, high elasticity is replied, natural anti-ultraviolet property and the brand-new fine hair product of anti-flammability.
Polylactic acid flocking villus of the present invention preparation is at first carried out vacuumize with polylactic acid slice, and fusion, reeling, fall to up-coiler through the spinning machine spinning, by the path barrel obtains as-spun fibre.Spin before this in process, spinning temperature is 220 ℃~240 ℃, and spinning speed is 1000~2000 meters/minute.
Some barrels of as-spun fibres are by the creel boundling, and carry out drawing-off and obtain not crimped tow, and wherein draw ratio is 2.5~4.0 times, and drafting rate is 200~400 meters/minute.Crimped tow is not cut, and length is 0.15~5mm as requested, and the best is 0.5~1.5mm, obtains polylactic acid flocking villus.
Tow or fine hair are carried out conducting electricity after the rinsing arrangement,, can obtain the PLA fine hair that electrostatic spinning is used again with fine hair drying, screening, packing.
Good effect of the present invention is the specific performance that has benefited from acid fiber by polylactic, and this fine hair has that environmental protection, high-strength, high elasticity are replied, natural anti-ultraviolet property and anti-flammability, for the flocking industry is developed a kind of novel product.
The specific embodiment
Embodiment 1
The manufacture order silk size is not crimped tows of 1.67 DENIER (dtex)

Embodiment 2
The manufacture order silk size is not crimped tows of 1.56 DENIER (dtex)
Polylactic acid slice is carried out vacuumize, melt spinning earlier, and spinning temperature is 220 ℃, obtains as-spun fibre through the path to up-coiler coiling, the bucket that falls, and winding speed is 1050m/min.As-spun fibre is carried out drawing-off, and draw ratio is 3.3 times, and drafting rate is 250 meters/minute, and obtaining filament number is not crimped tows of 1.56 DENIER (dtex).Tow is cut, and obtaining length is the PLA fine hair of 1mm, and fine hair is carried out rinsing, drying, screening, packing, promptly obtains can be used for the polylactic acid flocking villus of electrostatic spinning.
Embodiment 3
The manufacture order silk size is not crimped tows of 1.67 DENIER (dtex)
Polylactic acid slice is carried out vacuumize, melt spinning earlier, and spinning temperature is 232 ℃, obtains as-spun fibre through the path to up-coiler coiling, the bucket that falls, and winding speed is 1020m/min.As-spun fibre is carried out drawing-off, and draw ratio is 3.5 times, and drafting rate is 350 meters/minute, and obtaining filament number is not crimped tows of 1.67 DENIER (dtex).Tow is cut, and obtaining length is the PLA fine hair of 1mm, and fine hair is carried out rinsing, drying, screening, packing, promptly obtains can be used for the polylactic acid flocking villus of electrostatic spinning.
