Abstract
The invention relates to a dyeing process for cotton spandex core-spun yarn fiber. The process is as below: (1) uniformly winding the cotton spandex core-spun yarn fiber; (2) scouring and bleaching fro 60 min at 100 DEG C; (3) dehydrating and drying the cotton spandex core-spun yarn fiber subjected to scouring and bleaching; (4) uniformly winding the cotton spandex core-spun yarn fiber subjected to dehydration and drying; (5) dyeing with reactive dye, conducting soap boiling at the temperature of 90 DEG C, and then washing with water; and (6) dehydrating and drying the washed cotton spandex core-spun yarn fiber to obtain the dyed finished product. Compared with the prior art, the elastic yarn obtained by the invention through dyeing has the advantages of dyeing uniformity and small elasticity damage; and the process reduces the investment and operation of equipment, and has good application prospects.
Description
Technical field
The present invention relates to a kind of dyeing of fiber, especially relate to a kind of dyeing of cotton polyurethane core-spun yarn fiber.
Background technology
The dyeing of elastic cotton spandex, because sharply shrink when dyeing, so the cheese dyeing of routine to do, can only have special one-tenth cylinder and yarn steaming equipment just can resolve, and such equipment investment is large and technological process is long, causes the increase greatly of production cost.
Application number be 201110280266.2 Chinese patent disclose the dyeing and finishing method of brocade/people's cotton/spandex knitted fabric, comprise open width preshrunk, practice dye one to bathe, low temperature neutralization is soaped, acid dyeing, soap washing, dry and soft finish operation, described open width shrinking processes adopt gas steaming contracting width machine to carry out, described experienced dye one bathes operation for add 1g/1-2g/l refining degreaser in dye vat, the aqueous solution of 2g/l-3g/l soda ash, after 60 DEG C-80 DEG C process 15min-20min, add REACTIVE DYES again, 25g/l-70g/l glauber salt and 20g/l-25g/l soda ash, 60 DEG C-65 DEG C dyeing 50min-70min.Still there is the shortcoming of technological process complexity in the method.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and provide a kind of elastic force damage less, decrease the dyeing of the cotton polyurethane core-spun yarn fiber of equipment investment and operation.
Object of the present invention can be achieved through the following technical solutions:
A dyeing for cotton polyurethane core-spun yarn fiber, adopts following steps:
(1) by cotton polyurethane core-spun yarn fiber winder on cotton yarn loose type coning car, tension force is transferred to minimum, and density is 0.25-0.3g/cm
2, winding evenly;
(2) the uniform cotton polyurethane core-spun yarn fiber of winding is boiled drift 60min in the environment of 100 DEG C;
(3) the cotton polyurethane core-spun yarn fiber boiling drift carries out dewatered drying process;
(4) the cotton polyurethane core-spun yarn fiber after dewatered drying is winder on cotton yarn loose type coning car, and tension force is transferred to minimum, and density is 0.25-0.3g/cm
2, winding evenly;
(5) the uniform cotton polyurethane core-spun yarn fiber that reels dress cage is placed in dye tank, utilizes REACTIVE DYES to dye, and carries out soap boiling at 90 DEG C, then wash;
(6) the cotton polyurethane core-spun yarn fiber after washing, through dewatering and drying, namely obtains the finished product after dyeing.
Cotton polyurethane core-spun yarn fiber described in step (2) adds auxiliary agent when boiling drift, comprises hydrogen peroxide 4g/L, caustic soda 2g/L, and dispersion chelating agent 1.5g/L, stabilizing agent 1g/L, refining agent 2g/L, the bath raio of auxiliary agent is l:10.
Boil the cotton polyurethane core-spun yarn fiber after drift in acid and deoxygenation.
Cotton polyurethane core-spun yarn fiber described in step (5) also adds levelling agent, glauber salt and soda ash when dyeing, and the levelling agent concentration added is 1.5g/l, and glauber salt concentration is 30-70g/l, and soda ash concentration is 15-30g/l.
Described glauber salt divides three times and adds, and described soda ash adds at twice.
It is soda ash in 1g/l glacial acetic acid He unnecessary that cotton polyurethane core-spun yarn fiber also adds concentration when dyeing.
Compared with prior art, the dye elastic cotton dyeing yarn that obtains of the present invention is even, and elastic force damage is less, decreases equipment investment and operation, has good prospects for use.
