Abstract
The invention relates to a processing method of alkali-resistant dischargeable mercerized colored spun yarn, belonging to the field of spinning. The method comprises the following steps of: a, dyeing sliver, wherein the sliver is dyed with the required color by use of a dischargeable reactive dye containing two active groups of monochloro-sym-triazine and vinyl sulfone; b, spinning, wherein the dyed sliver obtained by the step a is spun with the true-color or dyed sliver according to a proportion; c, singeing and reeling the colored spun yarn obtained by the step b; and d, mercerizing the colored spun yarn obtained by the step c. The processing method provided by the invention originates the alkali-resistant dischargeable mercerized colored spun yarn, not only maintains the original features of the colored spun yarn, but also enables the colored spun yarn to be resistant to strong alkali mercerizing; the colored fabric has the alkali-resistant dischargeable performance; and the shortcoming that the common colored spun yarn is alkali-resistant but not dischargeable or is dischargeable but not alkali-resistant is overcome.
Description
Technical field
The present invention relates to the processing method of a kind of look spinning of textile technology field, specifically a kind of processing method with look spinning of discharge property and ability highly basic mercerising.
Background technology
Look spinning generally is the yarn that is spun into by two or more different color and luster fiber mixing, and the lining that the look spinning is made into has a kind of dim natural stylistic effects, and is very popular.Mostly colored fibre in the look spinning in the market is that cotton bulk fibre adopts K type or the reactive dyeing of KN type, lovely luster, and chromatogram is complete; Can form multiple style, but alkaline-resisting mercerising fastness is very poor, serious through fading behind the concentrated base mercerising; Color and luster withers secretly; Must carry out complementary color after the processing, strengthen the loss of human and material resources, energy aspect, production efficiency is low; Colored fibre in a kind of look spinning in addition adopts the high temperature dyeing, and mostly dyestuff is the s-triazine structure REACTIVE DYES, ability highly basic mercerising, but the discharge performance is not good.To sum up, alkaline-resisting can not the pulling out of look spinning can be pulled out not alkaline-resisting shortcoming and seriously hindered further developing and using of look spinning.
Summary of the invention
Alkaline-resisting can not the pulling out maybe of look spinning can be pulled out not alkaline-resisting shortcoming in the pin prior art of the present invention, but a kind of processing method of alkaline-resisting discharge fiber dyed yarn is provided, and enriched the kind of look spinning, enlarged the range of application of look spinning.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
But a kind of processing method of alkaline-resisting discharge mercerized spun-dyed yarns, step is following:
A. sliver dyeing uses the pulled out REACTIVE DYES that contain a chloro-s-triazine and vinyl sulfone double-active property base to dye the color of needs on sliver;
B. spinning is spinned the dyeing sliver of step a in proportion with true qualities or other dyeing slivers;
C. to the spinning of the look of step b by singe, reeling technology is singed, reeling; D. look spinning the carrying out mercerising of step c is handled.
The above-mentioned REACTIVE DYES that pull out have widespread production and sale in market, can pull out REACTIVE DYES like light ME type forever.
Mercerized yarn generally adopts the high temperature dyestuff; The i.e. dyestuff of a chloro-s-triazine and dichloro s-triazine; Make back road ability highly basic mercerising and its structure of brokenization not can process mariages light lining, and middle temperature dyestuff is the vinyl sulfone(Remzaol structure; Thereby highly basic can make the ether bond rupture on the dyestuff can not mercerising, thereby but the rongalite in the DISCHARGE PRINTING can destroy its dye structure forms the DISCHARGE PRINTING effect.The present invention adopts the s-triazine structure of existing alkaline-resisting group; The vinyl sulfone(Remzaol structure that can pull out is arranged again, thereby formed alkaline-resisting effect of pulling out, the mercerized yarn that obtains can carry out the highly basic mercerising; Its yarn-dyed fabric can carry out DISCHARGE PRINTING again, makes mariages light lining form different stylistic effects.
But the processing method of alkaline-resisting discharge mercerized spun-dyed yarns of the present invention, used cotton fiber are sliver; Coloured fibre weight accounts for 5%～85% of total weight of fiber in the look spinning.
Among the above-mentioned steps a there be the dyeing step: the enzyme pre-treatment, and washing, reactive dyeing, washing is soaped, washing.Enzyme pre-treating method wherein: scouring enzyme 2～4g/L, soda ash 0.05～0.08g/L, temperature are 50～60 ℃, and the time is 20～40min; Dyeing: dye strength (owf) is 0.01～8.0%, sodium chloride consumption 20～80g/L, soda ash consumption 10～20g/L, temperature are 50～60 ℃, and the time is 30～75min; The time of soaping is that 10～25min, temperature are 80～100 ℃.
In the above-mentioned d step, in the said mercerising step, alkali concn is in the treatment fluid: 28～32 Baume degrees, treatment fluid temperature: 18～20 ℃, apply tension force: stretch 0～4%, the processing time is 5 minutes 30 seconds～7 minutes and 30 seconds.
But the alkaline-resisting discharge look spinning that the present invention produces not only has the advantage and the characteristics of common mercerising look spinning; But and possesses the dual performance of the mercerising of anti-highly basic and discharge performance; Can be widely used in knitting and the tatting processing; Enlarge the scope and the kind of look spinning, promoted the overall quality of look spinning.
Compare with existing look spinning Technology, the advantage of processing method of the present invention is:
1. but changed common look the spin mercerising of anti-highly basic and the conflicting condition of discharge performance, enlarged the scope of application and the Application Areas of look spinning;
2. adopt sliver dyeing to replace traditional loose stock dyeing; The pre-treatment time shortens to 1～2 hour by 3～5 hours of routine, and the consumption of water, electricity and gas reduces by 30%, and dyeing time reduces more than 3 hours; Increase substantially operating efficiency, reduced spinning process difficulty and cycle;
3. adopt the enzyme treatment process of economic environmental protection to replace traditional high temperature alkaline scouring technology; Reduced damage to cotton fiber; Increased the spinnability of look spinning, with the spinning loss reduction by 2%～5% of look spinning, spinning count gets a promotion; Number is improved 10～20, can spin 80S/1 and 100S/1;
4. the yarn-dyed fabric of producing through this method has discharge property, makes the photochromic fabric of look spinning mariages have special discharge style, and kind is variation more.
Product after the inventive method processing; With 60s/2 (15% look sliver+85% true qualities sliver) is example, can reach following technical indicator: 1) yarn strength: 405czN, 2) yarn breakage percentage elongation 4.8%; 3) yarn evenness: 8.5, the 4) twist: 78 sth. made by twisting/10cm.
