Description
Technical field
The present invention relates to ring spinning new technical field, relate to the production method of a kind of bluish dogbane/staple cotton blended yarn line specifically.
Background technology
Along with the continuous enhancing of people's environmental protection and health care consciousness, green ecological textiles is more and more subject to the favor of people, take bluish dogbane as the bluish dogbane textiles of raw material starts to be subject to people common concern with the performance of its uniqueness.Bluish dogbane is a kind of bast fiber, fiber finer, powerful large, fiber integrate the gloss of silk, cotton softness, fiber crops well-pressed, there is the features such as well-pressed, smooth, good hygroscopicity, rapid heat dissipation and good permeability.Not only comfortableness is good for the textiles made of apocynum fibre, also contains the multi-medicament compositions such as cardiac glycoside, Quercetin, flavone compound, several amino acids because of fiber simultaneously, and has unique health-care function.In addition, bluish dogbane fabric also has antibacterial anti-corruption effect, after measured, after bluish dogbane fabric washing 30 times, its aseptic rate still higher than general fabrics 10-20 doubly, be natural anti-bacterial fibre.Therefore, bluish dogbane can be used for weaving healthy fabric, is called best natural textile fiber by many scholars, is the health fiber of 21 century.In addition, weaving face fabric drapability, antistatic behaviour that bluish dogbane and staple cotton blended yarn are made are better, and moisture absorption is loose wet fast, has the gloss as silk and feel.
For this, the present invention provides the production method of a kind of bluish dogbane/staple cotton blended yarn line.This technique comprises: apocynum fibre is carried out pre-shredding, and adds the finish warm water solution of 3%, heap storage health 24 hours; Long-staple cotton is obtained the cotton carded sliver through Blowing carding operation; Mix with the ratio of treated apocynum fibre according to bluish dogbane/long-staple cotton 35/65 after the cotton carded sliver is discerped; Again mixed bluish dogbane/long-staple cotton is obtained bluish dogbane/staple cotton blended yarn line by cotton spinning flow process opening and cleaning step, carding step, combing process, three road mixing in doubling step, Roving Frames and spinning process.Bluish dogbane and long-staple cotton can be made the second best in quality blended yarn by the present invention, this yarn makes apocynum fibre and long-staple cotton fiber complementation optimize, merge the antimicrobial health care function of bluish dogbane, and the sucting wet air permeability of long-staple cotton, make it to play respective feature, yarn formation structure is optimized, and yarn qualities is more excellent.
Summary of the invention
The object of the invention is the production method providing a kind of bluish dogbane/staple cotton blended yarn line, apocynum fibre and long-staple cotton fiber complementation are optimized, to merge the antimicrobial health care function of bluish dogbane, and the sucting wet air permeability of long-staple cotton, make it to play respective feature, yarn formation structure is optimized, and yarn qualities is more excellent.
To achieve the above object, realize the production of bluish dogbane/staple cotton blended yarn line, the present invention adopts following production method, comprises the following steps:
The first step, carries out pre-shredding by apocynum fibre, and adds the finish warm water solution of 3%, heap storage health 24 hours;
Second step, obtains the cotton carded sliver by long-staple cotton through Blowing carding operation;
3rd step, mixes with the ratio of treated apocynum fibre according to bluish dogbane/long-staple cotton 35/65 after being discerped by the cotton carded sliver;
4th step, obtains bluish dogbane/staple cotton blended yarn line by mixed bluish dogbane/long-staple cotton by cotton spinning flow process opening and cleaning step, carding step, combing process, three road mixing in doubling step, Roving Frames and spinning process.
Adopt above-mentioned production technology, bluish dogbane and long-staple cotton fiber can be made the good blended yarn of yarn quality, apocynum fibre mixes with long-staple cotton fiber by the 3rd step especially wherein according to a certain percentage, and the 4th step mixed bluish dogbane/long-staple cotton is obtained bluish dogbane/staple cotton blended yarn line by cotton spinning flow process opening and cleaning step, carding step, combing process, three road mixing in doubling step, Roving Frames and spinning process, optimize yarn formation structure.
