Abstract
The invention discloses a method for producing a cupro textile product. The method comprises the following steps of: respectively winding 120 deniers of cupro filaments and 14.6tex cupro filer blended yarns into a cone yarn, and then carrying out yarn bleaching, acid washing, deoxidation, yarn dyeing and soaping treatments; then spinning the yarns into greige cloth by using the cupro filer blended yarns as warp yarns and the cupro filaments as weft yarns; singeing, desizing and softening the greige cloth; and then carrying out posttreatment on the greige cloth to manufacture the cupro textile product. The cupro textile product produced with the method has good moisture control capacity and drape, is softer and more comfortable than other cotton products and is a new generation green product.
Description
Technical field
The present invention relates to textile technology field, relate in particular to a kind of method of producing cuprammonium silk manufacturing product.
Background technology
The technical process of the fabricator textile product of prior art comprises: with raw cotton through conventional operation opening picking, comb and parallel cotton fibers prior to spinning, drafting, rove, spun yarn, winder, yarn dyeing, turn over tube, section warping, sizing, weave half base, singe, move back boil float, mercerising, dye, soap, soft, oven dry and sewing to be to process textile home textile product.Above-mentioned technology is very suitable to the home textile product that adopts common yarn to make, and shortcomings such as feel is poor, low in glossiness can appear in the product that makes.
Summary of the invention
Technical problem to be solved by this invention provides a kind of the have good moisture control ability and the sense of dangling, and is soft comfortable, and has the method for the production cuprammonium silk manufacturing product of silkiness gloss and smooth feel.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of method of producing cuprammonium silk manufacturing product, float yarn, pickling, deoxidation, yarn dyeing and the processing of soaping after 120 dawn ammonia copper wire long filaments and 14.6tex ammonia copper wire fiber blend yarn be wound into a yarn respectively; Be as warp thread with said ammonia copper wire fibre blending yarn afterwards, the ammonia copper wire long filament is woven into grey cloth as weft yarn; Afterwards with said grey cloth through singe, destarch add soft after, said grey cloth is carried out post processing makes said ammonia copper wire textile product.
Winder adopts the JA014 automatic winder, and the groove drum rotating speed is 600r/min; Adopt spooler to carry out winder to the ammonia copper wire long filament; Its rotating speed is 150r/min; Adopt in the dyeing course dye liquor single current to, overcome the yarn density problem that swelling causes in water, guarantee the level dyeing of yarn; The ammonia copper wire home textile product filoplume of producing simultaneously is few, be easy to biodegradation, has excellent moisture absorbing and sweat releasing performance, kept the natural good soft comfort property of ammonia copper wire fiber, remarkable antistatic property.
Said ammonia copper wire fiber blend yarn is ammonia copper wire fiber, the cotton fiber blended yarn by weight 55: 45 proportionings, can certainly adopt ammonia copper wire fiber and the blended yarn of other fiber with various different proportionings.
The said yarn that floats is by bath raio 1: 4~8, handles 20~60min in the solution boiling to float; Said pickling is after in body lotion, adding citric acid by bath raio 1: 4~8, handles 5~15min down at 35~45 ℃; Said deoxidation is after in body lotion, adding deoxygenase by bath raio 1: 4~8, handles 5~15min down at 35~45 ℃; Said yarn dyeing is after in body lotion, adding yellow REACTIVE DYES and red REACTIVE DYES 5~15min, adds soda ash after adding glauber salt 5~15min respectively, is warming up to 55~60 ℃ then, dyeing 20~40min; Said soaping is by bath raio 1: 4~8, in body lotion, adds detergent, the 5~15min that under 90~100 ℃, soaps, and warp is washed for 75~85 ℃ afterwards, through 55~65 ℃ of hot water wash, uses cold wash at last again.
Said boiling floated in the solution 50~60 ℃ of treatment temperatures, and in the body lotion, biological scouring agent EZ-2100F volumetric concentration is 1.0~1.5ml/L; After handling 10~30min, add bleeding agent FC-2, volumetric concentration is that 1.0~1.5ml/L, stabilizing agent F-PL volumetric concentration are 1.5~3.0ml/L; The caustic soda volumetric concentration is 1.0~1.6ml/L, the hydrogen peroxide solution of 27.5wt% concentration, and volumetric concentration is 5~6ml/L; Be warming up to 85~95 ℃, handle 10~30min.
