Abstract

The invention relates to a processing method of alkali-resistant dischargeable mercerized yarns, which comprises the following steps of: a, spinning: spinning natural or man-made cellulose fibers which contain long staple cottons of different proportions into different numbers of single yarns or plied yarns according to a spinning technology; b, singeing and reeling: singeing and reeling the yarns obtained in the step a; c, mercerizing: mercerizing the yarns obtained in the step b; d, dyeing: adopting the dischargeable reactive dye which contains two active groups of mono chloro-s-triazine and vinyl sulfone to dye the mercerized yarns; and e, soaping, washing, wringing, drying and rewinding the yarns obtained in the step d. The mercerized yarn is endowed with a brand-new function, not only can the mercerized yarn resist to strong alkali mercerization, but also can the yarn dyed fabric of the mercerized yarn have dischargeable performance. Besides keeping the original characteristics of good strength, bright color, good glossiness and excellent color fastness of the mercerized yarn, the alkali-resistant dischargeable mercerized yarn is also endowed with the discharge printing style with more stereoscopic impression, and the processing method can be widely applied to textile and clothing industry.

Description

But a kind of processing method of alkaline-resisting discharge mercerized yarn
Technical field
The present invention relates to the processing method of a kind of mercerized yarn of textile technology field, but specifically a kind of ability highly basic mercerising has the processing method of the mercerized yarn of discharge performance simultaneously.
Background technology
Under the normal temperature, in finite concentration alkali lye, give the yarn certain force of strain, make its generation process sufficient, irreversible swelling be called the yarn mercerising.Mercerized cotton is top grade in the cotton, and the yarn after the organizine optical processing has highly polished, and is powerful good, the advantages such as gloss as the silk, and its fabric is in brute force, anti-fluffing and anti-pilling, all there is raising in various degree aspects such as dimensionally stable.Mercerized yarn is used on high-grade man's T-shirt more, is made into mariages light lining, after can satisfying lining, puts in order the requirement that mercerising does not fade, and mercerized yarn all adopts megathermal reactive dyeing, and this has just caused mariages light lining can not carry out the defective of DISCHARGE PRINTING.On road, back lining, need carry out DISCHARGE PRINTING if desired, the dyeing of warm type during then mercerized yarn must adopt, but the road can not carry out the mercerising processing after can causing lining like this.To sum up, the mercerising dyed yarn is alkaline-resisting can not discharge, but DISCHARGE PRINTING but shortcoming that can not alkaline-resisting mercerising has seriously hindered the further application of mercerized yarn.
Summary of the invention
But the present invention is directed to the alkaline-resisting problem of can not the discharge DISCHARGE PRINTING but can not alkaline-resisting mercerising of mercerising dyed yarn in the prior art, but a kind of processing method of alkaline-resisting discharge mercerized 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 alkaline-resisting discharge mercerized yarn, step is following:
A. spinning, the natural or man-made cellulose fibers that contains different proportion long-staple cotton is spun into the single thread or the strand of different numbers according to spinning process;
B. singe, reeling, with yarn singeing, the reeling of step a;
C. mercerising carries out mercerising to the yarn of step b and handles;
D. dyeing, but adopt the discharge REACTIVE DYES that contain a chloro-s-triazine and vinyl sulfone double-active property base that mercerized yarn is dyeed;
E. with the yarn of steps d soap, washing, water squeezing, oven dry and rewinding.
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 yarn according to the invention, among the above-mentioned steps a, used fiber comprises ability highly basic mercerisings such as long-staple cotton, medium staple cotton, bast-fibre and can adopt the natural or man-made cellulose fibers of reactive dyeing; Above-mentioned steps b singes, reeling technology is: the temperature of singing is 950~1050 ℃, and the speed of a motor vehicle is 850~1000m/min; The strand of reeling heavily is 250~550g; In the said mercerising step of above-mentioned steps c, alkali concn is 28~32 Baume degrees in the treatment fluid, and the treatment fluid temperature is 18~20 ℃, stretches 0~4%, and the processing time is 5 minutes 30 seconds~6 minutes and 30 seconds; Among the above-mentioned steps d, boiling and bleaching process is: 27% hydrogen peroxide solution, 4 ~ 6g/L, sheet alkali 2 ~ 4g/L, scouring agent SSS 1 ~ 2g/L, 90~100 ℃ of temperature, time 30~45min; Among the step e, dyeing: dye strength is that 1~10% (owf), sodium chloride consumption 20~80g/L, soda ash consumption 10~20g/L, temperature are 50-70 ℃, and temperature retention time is 30~75min; Among the above-mentioned steps f, the technology of soaping does, soaping agent 2~4g/L, and temperature is 90~100 ℃, the time is 15~20min.
But the alkaline-resisting discharge mercerized yarn that the present invention produces has been contained the multiple natural and man-made cellulose fibers that cotton textiles, linen-cotton, cotton day silk etc. can carry out the highly basic mercerising and can carry out reactive dyeing, can be widely used in the multiple production and processing of textile garment.Compare with existing look spinning Technology, the advantage of processing method of the present invention is:
The present invention gives mercerized yarn a kind of brand-new function, makes its both ability highly basic mercerising, but can make its yarn-dyed fabric have the discharge performance again.But alkaline-resisting discharge mercerized yarn is keeping intrinsic powerful good of mercerized yarn, and color is beautiful, outside the characteristics that fineness is good and COLOR FASTNESS is superior, has given it again and has had more relief DISCHARGE PRINTING style, can be widely used in the textile garment industry.
