Acid fiber by polylactic blended yarn woven fabric and production method
Technical field
The present invention relates to a kind of acid fiber by polylactic blended yarn woven fabric and production method.
Background technology
Acid fiber by polylactic is commonly called as zein fiber, and is biodegradable, the moisture absorbing and sweat releasing good permeability, and crease-resistant resilience is good, and tensile strength is high, has silky luster, and is soft, smooth, comfortable and easy to wear.Difficult combustion, with painted, also have antibacterial, deodorant function.From raw material, produce, use discarded to be the process of a Natural Circulation, to be a kind of environmentally safe that the ecological fiber of nonhazardous, PLA have very high exploitation and be worth.But the fusing point of acid fiber by polylactic is lower, and vitrification point is low, and to thermo-responsive, stressed being prone to is stretched, and weaving process requires harsh.
Bamboo fibre is the regenerated celulose fibre that raw material is processed through technologies such as catalyzing hydrolysis, spinning with the bamboo; Bamboo fibre intensity is big, and toughness and ABRASION RESISTANCE are stronger, and moisture absorbing and sweat releasing, permeability are superior to cotton fiber; Bacteriostatic deodorizing; Be rich in gloss and soft, and dyeability being good, is that a new generation starves " green fiber ".But the bamboo fibre brute force is low, and cohesive force is poor between fiber, and the fabric shrinkage is big, and shape-retaining ability is poor.
Niu Daier is to be a kind of high-tenacity fiber of raw material production with reproducible high quality cotton or wood pulp; Fiber is keeping on the viscose good characteristic basis; Because brute force, wet modulus that it is suitable; Superior elongation at break and unique high crimpiness make product have better weaving machinability.Niu Daier quality softness is smooth, and the silk quality sense is strong, has good hand feeling and dangles sense, and the fabric shape-retaining ability is good, is prone to arrange wash resistant, anti-fold; Moisture permeability is superior to cotton, and is comfortable and easy to wear.
Keeping acid fiber by polylactic, bamboo fibre and Niu Daier separately under the situation of advantage, providing a kind of and be easy to woven acid fiber by polylactic blended yarn woven fabric and production method is the thing of extensively being paid close attention to.
Summary of the invention
According to above deficiency of the prior art; The technical problem that the present invention will solve is: provide under a kind of prerequisite that can keep ecological separately advantage of acid fiber by polylactic, bamboo fibre, Niu Daier and premium properties; It is good also to have shape-retaining ability; Good springiness is easy to woven acid fiber by polylactic blended yarn woven fabric and production method.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of acid fiber by polylactic blended yarn woven fabric and production method, the acid fiber by polylactic, bamboo fibre and the Niu Daier blending that it is characterized in that adopting following weight percent to form are weaved and are formed:
Acid fiber by polylactic 35-65
Bamboo fibre 60-30
Niu Daier 5-10
The production method of acid fiber by polylactic blended yarn woven fabric comprise spin-weave cotton cloth-print and dye-later stage arrangement four big production craft step, wherein
A, spinning
Comprise following operation: blowing-comb and parallel cotton fibers prior to spinning-drafting-rove-spun yarn-winder
1., cotton cleaning process
Acid fiber by polylactic, bamboo fibre, Niu Daier be the blowing rolling respectively
A, acid fiber by polylactic: the mode that blowing is adopted " duty is grabbed less and grabbed, how loose tip-tap ", strengthen cotton lap pressure, carry out preliminary treatment, the blowing process condition:
Cotton rolling weight g/m 420
Fixed length m 35.58
Hired roughneck r/min 380
B, bamboo fibre: adopt blow speed little, hired roughneck's range amplifies, and reduces cycle, and the combing machine for fur duty is grabbed, grabbed less, strengthens the shredding volume, and the comb volume is quantitatively light, to reach abundant shredding, alleviates the combing load, the blowing process condition:
C, Niu Daier: to the characteristics of Niu Daier fiber, many pines are few to be beaten, many combs are few falls to being principles, returns to spend and causes too much cotton knot for reducing fibre damage and hired roughneck, suitably reduces hired roughneck's speed;
2., carding step
A, acid fiber by polylactic
The carding process condition is:
The cylinder cover plate mm 0.2~0.25 that spaces
Cylinder rotating speed r/min 330
Licker-in rotating speed r/min 799
B, bamboo fibre
The carding process condition is:
Cylinder rotating speed r/min 330
Licker-in rotating speed r/min 810
Weight of card sliver g/5m 20g/5
C, Niu Daier
The carding process condition is by being:
Cylinder rotating speed r/min 330
Licker-in rotating speed r/min 800
Weight of card sliver g/5m 19g/5
3., mixing in doubling step
Adopt the drafting mixed method, the control mixing ratio, roller gauge is suitably amplified, and intensified pressure suitably improves and stretches oneself and yawn multiple;
4., rove operation
Back zone drafting multiple is 1.18, and the total draft multiple is 9.142;
5., spinning process
First break draft multiple 1.25, total draft multiple 52.027;
6., winding procedure
Waxing requires forming, does not have broken end, and nothing is caught;
B, weave cotton cloth
Comprise: warping-sizing-denting-weave-Xiu knits-packing process, wherein
Process conditions are following:
Sizing speed m/min 70
Sizing biological starch slurry, polyester starch slurry
In addition, weave the employing air-jet loom weaving.
C, printing and dyeing, finishing process
Comprise: turn over cloth-margin to seam-singe-destarch-boil and float-dye-softness-tentering-baking operation, wherein
1., during margin to seam, stitch is tight, joint is smooth, it is strong that margin to seam is straight, encrypt at two, prevents the crimping fold;
2., in the destarch process: greater than 50%, adopt the cellulose fibre desizing agent like bamboo fibre; Like acid fiber by polylactic greater than 50%,
Use the Dystar refining agent, 55~65 ℃ of destarch temperature;
3., boil when floating, regulate PH to 4-5, temperature is 95 ℃, the time is 55 minutes;
4., when soft, adopt softener one to soak one and roll;
5., during tentering, adopt the hot blast tentering, the tentering temperature is 120 ℃, and the tentering time is 40 seconds.
The ratio of described acid fiber by polylactic, bamboo fibre, Niu Daier is 35/60/5,44/50/6,53/40/7,60/30/10.
Pass through test of many times; The manufacturing technique that filters out acid fiber by polylactic, bamboo fibre, Niu Daier blend fibre prescription and be fit to makes three kinds of fibers have complementary advantages, and is keeping under the prerequisite of advantage separately; Also improved the glass temperature range of acid fiber by polylactic; Make and to weave easilier, improved brute force, the ANTIPILLING ability of lining, and further improved the shape-retaining ability of lining.
The beneficial effect that the present invention had is:
1, keeps acid fiber by polylactic, bamboo fibre, Niu Daier natural ecological function and premium properties separately, also had good springiness, advantage that shape-retaining ability is good.
2, also improved the glass temperature range of acid fiber by polylactic, make weave easier.
3, improve brute force, the ANTIPILLING ability of lining, and further improved the shape-retaining ability of lining.
