Abstract
The present invention discloses a method for dyeing gossamer/wool, gossamer cotton, gossamer/bast and other blended fabrics by using paint. Gossamer blended fabrics are used as raw materials which are pretreated by a polyfunctional compound with polyamine and polyalcohol, a technology formula is optimized by a special dyeing adhesive, and then the target products are acquired. The method of the present invention has the advantages of technology simplification and energy source saving and solves the problems of uneven dyeing and color difference existing in the dyeing of the gossamer blended fabrics. The dyed gossamer blended fabrics have the advantages of soft hand feeling, low formaldehyde content and stable product quality, and is suitable for industrial production, and the color fastness achieves the national standard.
Description
Technical field
The invention belongs to the fabric finishing technical field, relate in particular to a kind of colouring method of tencel blended fabric.
Background technology
The said tencel blended fabric of the present invention is a kind of broad-spectrum knit product.
It silk (Tencel fiber) can be formed BLENDED FABRIC such as a day silk/cotton, tencel/wool, day silk/fiber crops respectively with cotton, hair, fiber crops, usually dyeing adopts REACTIVE DYES, because high swelling, the adsorption rate of day silk are fast, cause the suction look of different fibers inconsistent, easily produce look flower, aberration phenomenon, tencel blended thing adopts two or more dyestuffs to dye respectively mostly, solve two kinds of problems that fiber can not dye simultaneously, there is shade deviation in the dyeing, cause look flower, aberration, unstable product quality after the dyeing, feel is poor, and COLOR FASTNESS is undesirable; And technological process is longer, and environmental issue is outstanding, and cost is higher.
Summary of the invention
The technical problem that the present invention solves provides a kind of tencel blended coloration of textile materials method, and poor to overcome the dyeability that exists in the prior art, technological process is long, and environmental issue is outstanding, the higher deficiency of cost.
Technical conceive of the present invention is such: with tencel blended fabric is raw material, adopts the polyfunctional compound of the many alcohol of polyamines to carry out pre-treatment, optimizes technical recipe with the special dyeing adhesive, obtains target product of the present invention.Therefore the feel of product, content of formaldehyde, COLOR FASTNESS are improved.
Method of the present invention may further comprise the steps successively:
1) textile dyeing pre-treatment: in industry washer, add the polyfunctional compound aqueous solution of the many alcohol of pretreating reagent polyamines, its concentration is 10g/l～20g/l, drop into tencel blended fabric, be warmed up to 75～85 ℃ in the stirring gradually, keep drying with centrifugal dehydrator after 20～40 minutes;
2) textile dyeing: in industry washer, add the pigment printing paste aqueous solution, pigment printing paste is the accurate conventional products of Shanghai printing ink emblem mark, coloring agent concentration is 0.5g/l～5g/l, tencel blended fabric after the input pre-treatment, be warming up to 75～85 ℃ in the stirring, kept 20～40 minutes, and dried with centrifugal dehydrator;
3) post processing: in industry washer, add the adhesive that multi-component copolymer macromolecule compounds such as acrylate, acrylonitrile obtain, its concentration is 40g/l～60g/l, crosslinking agent 5g/l～15g/l, drop into the tencel blended fabric after dyed, room temperature was stirred 5～20 minutes, dry with centrifugal dehydrator, dry with drum-type ring baking machine again.
Wherein: natural BLENDED FABRIC is a kind of in tencel/wool blending ready-made clothes, day silk/cotton blending, the sky silk/numb blending ready-made clothes, pretreating reagent NA is the polyfunctional compound of the many alcohol of polyamines, the textile dyeing agent is accurate conventional products 8204 Huangs of Shanghai printing ink emblem mark, adhesive NB is multi-component copolymer macromolecule compounds such as acrylate, acrylonitrile, and crosslinking agent is that crosslinking agent EH is a Shanghai auxiliary agent conventional products.
The said product of the present invention is pressed GB18401-2001 and is measured content of formaldehyde, presses FZ/T73008-1997 and measures fastness to rubbing.Test through Shanghai textile printing and dyeing product quality prison inspection point with the product that colouring method of the present invention obtains: content of formaldehyde is 4.7～5.6ppm, and far below the desired value 20ppm of infant's control, fastness to rubbing is 4～5 grades, reaches excellent index.
The present invention has simplified technology compared with prior art, and energy savings has solved look flower, aberration problem that tencel blended fabric exists in normal dyeing; Tencel blended fabric product after the dyeing is soft, and content of formaldehyde is low, and COLOR FASTNESS is up to state standards; Constant product quality is suitable for industrialized production.Especially in the dyeing of sky silk/wool-blend fabric beyond example, do not see the report in the dyeing on sky silk/wool-blend fabric, have good dyeability and Practical Performance.
