Abstract

The invention relates to a processing method for a blended dischargeable spun-dyed yarn in the field of textile. The blended dischargeable spun-dyed yarn is produced according to the following steps: (a) a fibre ribbon is dyed, i.e., a cellulose fibre ribbon with certain quality is chosen and dyed into a needed color by adopting medium-temperature reactive dye; (b) blending is carried out, i.e., according to the blending technique, the fibre ribbon dyed in step a is blended with other varieties of fibres according to requirement and different proportions; (c) according to the requirement of production, the spun-dyed yarn in step b is singed and reeled; (d) according the varieties of the fibres and the requirement on alkali resistance, the spun-dyed yarn in step c is selectively mercerized. The processing method adopts fibre ribbon dying to replace conventional loose fibre dying, thus shortening the flow of spun-dyed yarn processing, moreover, the fibre ribbon is blended with the other varieties of fibres, so that different styles of blended spun-dyed yarns can be produced, and furthermore, the method has a discharging function, and therefore is a brand new dischargeable spun-dyed yarn-processing method.

Description

But a kind of processing method of blending discharge fiber dyed yarn

Technical field

The present invention relates to the processing method of a kind of look spinning of textile technology field, but the processing method that specifically a kind of blended fibre knitwears discharge look that adopts brand-new processing method to produce spins.

Background technology

The spinning of blending look generally is the yarn that is spun into by two or more different cultivars fiber mixing.The spinning of blending look directly utilizes colored fibre cellulose fiber and the spinning of other kind fiber mixing; Do not increase the consumption of the water and the energy; Do not increase sewage emissions, solve the problem that blended yarn when dyeing resisdye is brought fully, 50 tons of use that reduces water per ton and sewage discharges; Reduce by 5 tons of steam consumptions, more than power saving 1000 degree.Because nonactive dyeing is adopted in the dyeing of other fiber in the spinning of present blending look, cause in the discharge process, can't carrying out effective discharge, and the present invention adopts other fiber blend of sliver dyeing and non-dyeing, thereby can reach the effect of discharge.

Summary of the invention

The present invention is directed to the nonactive dyeing of above-mentioned employing and cause to carry out in the discharge process problem of effective discharge, but a kind of processing method of novel blending discharge fiber dyed yarn is provided.

In order to solve the problems of the technologies described above, the invention provides following technical scheme:

But a kind of processing method of blending discharge fiber dyed yarn, step is following:

The dyeing of a, ribbon, the warm type REACTIVE DYES were dyed the color that needs during the ribbon of choosing the certain mass cellulose fibre adopted; B, blending mix yarn with the fiber of other kind by different proportion with the coloured fibre bar of step a as required in proportion according to blending technology;

C, according to production requirement to the spinning of the look of step b by singe, reeling technology is singed, reeling;

D, according to the kind of fiber and alkali resistance require to look spinning the carrying out selectivity mercerising of step c handle, look pulls out or dawn.

The warm type REACTIVE DYES have widespread production and sale in above-mentioned on market, like Taiwan light KE type forever.

But the processing method of novel blending discharge fiber dyed yarn of the present invention, used fiber are the ribbon of cellulose fibre, warm nature reactive dyeing in all can adopting, and coloured fibre accounts for 10%～95% of fiber total amount.Other fibers are terylene, acrylic fibers, polyamide fibre, viscose glue, day silk, wool or silk.

The dyeing step comprises: enzyme pre-treatment, reactive dyeing and soap.Wherein, the enzyme pre-treating method is: scouring enzyme 1～2g/L, soda ash 0.05～0.07g/L, temperature are 45～55 ℃, and the time is 30～40min.During reactive dyeing, dye strength (owf) is 0.5～9.0%, sodium chloride consumption 10～80g/L, soda ash consumption 10～20g/L, temperature are that 60 ℃, time are 30～75min.Soap time 15～25min, soaping agent 1～2g/L, temperature is 90～100 ℃.The mercerising step is that alkali concn is in the treatment fluid: 28～30 Baume degrees, treatment fluid temperature: 18～20 ℃, apply tension force: stretch 0～2%, the processing time is 5 minutes～6 minutes.

But the blending discharge look that the present invention produces spinning has that production procedure is short, and the spinning difficulty is low, and advantages of energy saving and environmental protection can be widely used in knitting and the tatting processing, but has enlarged the scope and the kind of the spinning of discharge look.

Compare with existing look spinning Technology, the advantage of processing method of the present invention is:

But the spinning of 1 discharge blending look is promoted to a new height with the manufacture field of look spinning; The scope of application and the Application Areas of look spinning have been enlarged; It adopts the dyeing of cellulose fibre bar to replace traditional loose stock dyeing; But introduced the processing method of other cellulose fibre blending discharge look spinning except that cotton simultaneously, this has changed the situation of having only cellulose fibre look spinning just can carrying out DISCHARGE PRINTING, and it is powerful good that the look that obtains spinning has; The characteristic that COLOR FASTNESS is high is widely used in T-shirt, overcoat and straight-bar machines field;

2, adopt the enzyme treatment process of economic environmental protection to replace traditional high temperature alkaline scouring technology, reduced the damage to cotton fiber, increased the spinnability of look spinning, spinning count gets a promotion.

To sum up, but the blending discharge look that the present invention produces spinning has kept the peculiar style of look spinning color-woven fabric, but has enlarged the kind of discharge look spinning simultaneously, has improved the market competitiveness of look spinning.
