Abstract

Disclosed is a colored spinning technology of cashmere, cotton, and tencel blended yarn. The colored spinning technology include the following processes: blowing and carding through a blowing-carding combining short-process machine, drawing twice through an A272 drawing frame, roving through an A454 roving spinner, fine spinning through an A513spinning frame, spooling through a 338 Schlafhorst automatic winder, doubling through a TSB-36 doubling winder, and two-for-one twisting through a TDN-120 two-for-one twisting machine. Due to the fact that after fibers are dyed, elasticity and strength of the fibers are lost to a certain degree, during spinning, each process is designed according to the features of colored spinning. The colored spinning technology has the advantages that according to the advantages of colored spun yarn, the cashmere, the cotton, and tencel blended yarn are respectively dyed, through the colored spinning technology, technology innovation is conducted on cotton spinning equipment, and not only is novel blended yarn generated, but also the contradiction of use of acid-base property of dye when protein fibers and cellulosic fibers are dyed simultaneously is avoided, and therefore good effect is achieved, novel color, luster, and texture of rear garment materials are endowed, and additional value and technical content of a product are improved.

Description

The look spinning process of a kind of cashmere, cotton, tencel blended yarn

(1) technical field

The present invention relates to a kind of technique of field of textiles, particularly relate to the look spinning process of a kind of cashmere, cotton, tencel blended yarn.

(2) background technology

Look spins relative true qualities and spins, and is exactly first fiber to be dyed colored fibre, then with two or more different colours or different types of fiber after fully mixed, is spun into the spinning technique with unique color blending effect yarn.The look textile product is knitted product, dyeing and printing products with respect to true qualities, has obvious environment-friendly advantage, color advantage and scientific and technological advantage.

Cashmere fiber has fabulous hygroscopicity, elasticity and warmth retention property.The good wearability such as the cotton fiber product is comfortable and easy to wear, has extremely strong moisture absorbing, and that tencel fiber has is ventilative, hygroscopicity is strong, smooth, and have high-tenacity, embrace and the large characteristic of power.With cashmere, cotton, silk fiber blended, can have complementary advantages, separately advantage of performance preferably integrates well-pressed, good springiness, ventilative smooth characteristic, and product specification is improved greatly, is desirable spring and autumn high-grade fabric.

Cashmere is protein fibre, uses ACID DYES during normal dyeing.Cotton and tencel fiber is cellulose fibre, uses basic dyeing.Cashmere, cotton, tencel blended yarn if common piece dyeing finishing is used in the essential color fiber blending, can increase the difficulty that dye because the chemical characteristic of fiber is different, and cause the damage to fiber, affect quality.At present, the look spinning process of cashmere, cotton, tencel blended yarn awaits further to study.

(3) summary of the invention

The present invention is based on above-mentioned purpose, the look spinning process of a kind of cashmere, cotton, tencel blended yarn is provided.

Technical scheme of the present invention is to realize like this.

The look spinning process of the cashmere of this programme, cotton, tencel blended yarn, look spinning process flow process is as follows:

The short flow process machine of clear comb associating, A272 drawing frame---twice, A454 Speed frames, A513 fine spining machine, 338 Schlafhorst automatic winders, TSB-36 doubling winder, TDN-120 two-for-one twister.

Because brute force, elasticity by the rear fiber that dyes all have certain loss, therefore when spinning, each procedure will design according to the characteristic that look spins.

Blowing, comb and parallel cotton fibers prior to spinning, drafting, Roving Frames should adopt gently quantitatively, slow train is fast, the good spinning process that shifts, and reduce 10%-15% when speed of a motor vehicle ratio spins gray yarn, produce with minimizing cotton knot short flannel; Because the short flannel that needs in fiber to get rid of, cotton assorted less can suitably dwindle noil and space; While improves to mix all and reduces aberration with degree in order to control resultant yarn weight CV% and deviation of weight, carries out three roads at mixing in doubling step and mixes also; Because final products are knitted fabric, so ramie yarn twist and the grasp on the low side of the double twisting twist, the twist of double twisting will be in 55% left and right of ramie yarn twist; To suitably reduce winding speed at winding procedure, control the filoplume growth rate.

Usefulness of the present invention is: the present invention is according to the advantage of look spinning, cashmere, cotton, tencel fiber are dyeed respectively, by the look spinning technique, carry out a series of technology innovation on cotton spinning apparatus, both produced a kind of brand-new blended yarn, the contradiction when having avoided again protein fibre and cellulose fibre to dye simultaneously on the Acidity of Aikalinity of use dyestuff has obtained good effect, give the rear portion garment material brand-new color and luster texture, improved value-added content of product and technology content.

(4) specific embodiment

The invention will be further described below in conjunction with embodiment.

Embodiment:

The present embodiment relates to the look spinning technique of a kind of cashmere, cotton, tencel blended yarn, and deisgn product is 40/30/30 cashmere/cotton/sky silk product, is a kind of higher gears clothes raw material, thus from following some set about.

1, choose raw material: cashmere fiber selects to be suitable for the specification of cotton spinning apparatus spinning, fibre length 28-35mm, 16 microns of average diameters.For making the raw cotton after dyeing still keep certain elasticity, and strength loss is reduced, reduce cotton knot, impurity and short flannel in cotton fiber, select JC60S combed cotton bar as the raw material of dyed cotton.Tencel fiber is selected A100, and specification is 1.26D*38mm.

2, carry out ingrain: should improve dyefastness in the dyestuff apolegamy and make again the rear fiber of dyeing keep certain elasticity and coefficient of friction, thus to add appropriate auxiliary agent and finish in former cotton dyeing, and improve dye uniformity.

3, optimize spinning process: on the cashmere fiber after dyeing, evenly spray and stewing 24 hours of crude oil, make the abundant moisture absorption of fiber softening, twine roller, roller phenomenon with what static in the solution spinning process caused.

Dyeing cashmere after processing, cotton, tencel fiber are manually mixed according to design proportion is preliminary, then drop into clear comb and unite short flow process machine.Look spinning process flow process is as follows:

The short flow process machine of clear comb associating, A272 drawing frame (twice), A454 Speed frames, A513 fine spining machine, 338 Schlafhorst automatic winders, TSB-36 doubling winder, TDN-120 two-for-one twister.

Because brute force, elasticity by the rear fiber that dyes all have certain loss, therefore when spinning, each procedure will design according to the characteristic that look spins.

Blowing, comb and parallel cotton fibers prior to spinning, drafting, Roving Frames should adopt gently quantitatively, slow train is fast, the good spinning process that shifts, and reduce 10%-15% when speed of a motor vehicle ratio spins gray yarn, produce with minimizing cotton knot short flannel.Because the short flannel that needs in fiber to get rid of, cotton assorted less can suitably dwindle noil and space.While improves to mix all and reduces aberration with degree in order to control resultant yarn weight CV% and deviation of weight, carries out three roads at mixing in doubling step and mixes also.Because final products are knitted fabric, so ramie yarn twist and the grasp on the low side of the double twisting twist, the twist of double twisting will be in 55% left and right of ramie yarn twist.To suitably reduce winding speed at winding procedure, control the filoplume growth rate.

Technique effect

Use above technological development 40/30/30 cashmere/cotton/sky silk product, now successfully spin the yarn of various numbers, weave the fabric of different-style, its clothes plentiful well-pressed, softly smooth, color and luster is soft, comfortable ventilating, be desirable high-grade fabric, be received by the market.
