Abstract
The present invention relates to a production process of spun silk yarn, in particular it is a process using spun silk leftover bits as raw material and using cotton spinning equipment to produce 50-80Nm/2 spun silk yarn. Said invention uses general cotton spinning and carding processes and equipments, and only has need to make a proper regulation and improvement on the equipments in all procedures, and can make mass production. As compared with existent technique, its process flow is short, raw material and production costs are low, labour productivity is high, and rate of finished products is high.
Description
What the present invention relates to is the production technology of spun silk yarn, and particularly a kind of is raw material with thin,tough silk, silk leftover bits and pieces, with the technology of the low spun silk yarn of cotton yarn common carding machine production.
The technological process of spun silk factory production spun silk yarn is longer, and labour intensity is big, and labor productivity is low.Early seventies, the carding of some factory's worsted spinnings both at home and abroad and combing equipment are introduced the silk spinning system, form a new process route, are called combing, but owing to row yielding is not high former thereby fail to form weather, still based on traditional schappe system processing.
At present, though domestic have the minority cotton mill with silk spinning factory, the general obsolete spun silk leftover bits and pieces of silk spinning factory: as silkworm cocoon waste silk, silk flosssilk wadding, noil, adopt carded spinning unit Processes and apparatus to come a thick aerophane of production RING SPINNING, and the open-end spinning aerophane.This technology can only be produced 40Nm～12Nm low count yarn, and bar is dried poor, and fault is many, and impurity is many, and the retaining of product is inferior low.And can not produce spun silk of fine quality with thin,tough silk, silk leftover bits and pieces with silk spinning equipment and technology.
Application number is: 93115382.4 patent application discloses a kind of leftover bits and pieces with silk spinning factory, silk spinning factory, utilize the continuous technological process of spinning the high-quality spun silk yarn of combing device fabrication 50Nm/2～70Nm/2, for utilizing again of spun silk leftover bits and pieces opened up new way, has bigger economic benefit, yet this technological process is longer, and row yielding is lower.
The object of the present invention is to provide a kind of technological process shorter, the surplus technology of on cotton a tree, used in making timber for boats common carding machine, producing spun silk that row yielding is higher with thin,tough silk, silk leftover bits and pieces.
Technology of the present invention is undertaken by such order, is about to thin,tough silk, a silk leftover bits and pieces passes through: pretreatment of raw material → scutching cotton opening or cleaning → carding machine combing → drawing frame twice carry out and close making continuous bar → Speed frames → fine spining machine → twisting machine → bobbin winder → reeling → reeled yarn with drawing-off and becoming to wrap.
In above-mentioned scutching cotton opening or cleaning operation, scutcher hired roughneck's speed is controlled to be 1000～1200 rev/mins, and lap is heavy-and be 300～350 gram/rice, volume length is 20～23 meters; In the operation of carding machine combing, the carding machine licker-in speed is controlled to be 1000～1100 rev/mins, and doffer speed is 12～15 rev/mins, adopts the stripping roller device; In mixing in doubling step, drawing frame speed is 700～900 rev/mins, its upper leather roller is carried out antistatic handle; Fine spining machine speed is controlled to be 160～180 rev/mins; Twist factor is 290, and district's traction proportioning is that the back zone selects 1.15～1.35 before and after the spun yarn, and the front and back roller adopts the moccasin roller, and surface anti-static is handled.
The detailed description of one embodiment of the present of invention is such: promptly the spun silk leftover bits and pieces is through certain preliminary treatment, at scutching cotton operation proportioning raw material, distributing cotton needs the different requirements of basis to product, carry out the different proportion proportioning, scutching cotton is mixed into the master with shredding, the grasp less than normal of spacing, hired roughneck's speed is suitable fast, be controlled to be 1100 rev/mins, effective in order to shredding, and pull, interrupt some overcut fibres.Cotton rolling weight is light partially, select 300 gram/rice, long 20 meters of volume, carding machine are noted emphatically dividing comb and shifting, under the situation of not twining cylinder, dwindle carding isolation distance, for well, increasing licker-in speed is 1100 rev/mins with the effect of spinning the Ge Lafu card clothing in the moulding of card clothing as far as possible, reduce doffer speed to 15 rev/min, adopt the stripping roller device, each rotating ratio is carried out the optimised process configuration, in order to combing and shift strong the branch; And the strip adoption low velocity, be 700 rev/mins, the pressurization of laying equal stress on suitably strengthens the roller diameter, upper leather roller is carried out antistatic handle; In process of roving, note adjusting spacing and tension force, on false twister, test selection; Spinning process focuses on the optimal process, and speed remains on about 170 rev/mins, and twist factor is chosen in 290, and back area draft proportioning back zone is chosen as 1.15 before the spun yarn, and the front and back roller adopts the moccasin roller, and the surface needs anti-quiet processing, and the steel traveler weight is grasped.
By the spun silk yarn of above-mentioned explained hereafter of the present invention, it is as follows that the related item of 60Nm/7 hair spun silk yarn quality restriction is carried out quality inspection:
(videing infra)
From above several indexs, except that breaking length does not reach the standard, other several indexs all meet or exceed silkworm silk spinning ministry standard.The substandard reason of breaking length is because the raw material that adopts is due to the spun silk leftover bits and pieces.And this brute force is all higher than other vinylon and cotton blend of cotton mill, chemical fibre brute force, can be used as spun silk carpet, knitwear and is used for weaving cotton cloth.
The present invention has the extremely long-pending effect of following several aspects owing to described technology:
1, takes full advantage of thin,tough silk factory, the obsolete spun silk leftover bits and pieces of Silk Mill, enlarged raw material sources; Widened weaving market.
2, technological process is short, and producing cost is low, the labor productivity height, and raw material row yielding height can significantly reduce costs, and is 4～6 times of other table benefit.
3, the equipment that technology adopted is existing cotton a tree, used in making timber for boats common carding machine, suitably adjusts the improvement back and just can produce in batches, and different product is finally required to adopt different technology roads, not only economy but also practicality.
4, this technology can be produced the spun silk yarn of 50Mn/2～80Nm/2, through knitting or weave cotton cloth into dress after, have good hygroscopicity, feel is pleasant, and is comfortable and easy to wear, advantages such as novel in style.
5, the development of this technological process, also can with blending such as other hair, fiber crops, chemical fibre, produce the high gear product of different performance, satisfy needs international, the domestic market.
