Abstract
The invention provides a method for producing ramie siro spinning superfine yarns, which is characterized in that the method comprises the following specific steps of: adopting a siro spinning method to mix the ramie roving with the water soluble vinylon roving on a spinning machine during the traction process, thus spinning a blended yarn with the fineness of 100-300 counts; combining the blended yarns, removing the vinylon, washing the blended yarn by water and drying the blended yarn to obtain the ramie superfine yarns. The method has the advantages of compact structure of the product, high yarn strength and good yarn evenness uniformity.
Description
Technical field
The present invention relates to a kind of production method of ramie siro spinning superfine yarns, belong to the Textile Engineering technical field.
Background technology
Ramee is the superior fiber of quality in the bast-fibre, and its fabric has powerful high, moisture absorption, diffusing wet fast, good permeability, good wearability such as antibacterial, and because of its rigidity height, stiffening, not sticking body especially is fit to make the product in summer, is a kind of green textile raw material of extensively being favored.In recent years, variation has all taken place in people's life style and fashion industry, summer, lining was to frivolous, gentle refreshing, ventilative, comfortable and healthy fashion trend development, the consumption idea that recover one's original simplicity, back to nature, comfortable health etc. is new is risen, save up strength to start out in huge consumption markets such as bast fibre spinning clothes, interior decoration, health care product, ramie textile already faces important opportunity to develop.But the defective that bast-fibre is intrinsic: rigidity is big, and is stiffening, flexible not enough, and China's ramie textile process technology and whole equipment are backward relatively, and technological level is low, causes product type single, and structure is identical, becomes yarn count low.The pure class ramie yarn that spins that textile enterprise produces is 24 public basically, 36 public two kinds, 48 public above kinds are seldom produced in batches, the ramie textile product are based on 36Nm and following thick heavy weave, fabric feeling is thick and stiff, wrinkling, prodding and itching feeling is serious, the class of product, technical merit and added value of product are low, add and also do not have own outstanding apparel brand, so these clothes are consumed the location class abroad and mostly are low and middle-grade, the Application Areas that has seriously restricted the ramee textiles expand and the ramee textiles in the competitiveness of international market, add the technology barriers of European Union, restricting the development of ramie industry.Therefore, people are devoted to the high branching research of ramie yarn for a long time, but, because the restriction of raw material and spinning technology, make progress limited, existing ramie high-count yarn spun method is all ramie sheer (being a kind of woven fabric in fact) that Hunan Huasheng Zhuzhou Xuesong Co., Ltd. produces, its process using be that ramie and water soluble vinylon blending are made blended yarn, in back arrangement process (generally being at desizing) polyvinyl is dissolved away after being made into fabric, the ramie yarn number in the cloth can reach 300 public even 500 public.But there is following problem:
1. owing to move back the performances such as brute force of dimension back yarn (line) and significantly worsen, can not make and be directly used in woven or knitting height and prop up ramie yarn (line);
2. the woven fabric structure that is made into of ramie/polyvinylalcohol blended yarn is tight, and water soluble vinylon difficulty is decorporated, and washing, stoving process time are long;
3. after fabric moved back dimension, the density of pure ramie woven fabric and brute force were very low, can only be used to do gauze kerchief etc., can not do DRESS FABRIC etc.;
4. the water solution temperature of water soluble vinylon may make the part water soluble vinylon dissolve in technical process such as sizing between 30 ℃～100 ℃, and the size of its meltage influences yarn strength, structure and weaving process;
5. the hybrid mode of Cai Yonging is that bulk fibre mixes or strip mixes, what may occur distributing in a certain partial cross section of yarn is polyvinyl entirely, situations such as broken end will appear after causing this place to move back dimension, in addition, when bulk fibre or strip mix, the internal layer that must some polyvinyl be distributed in yarn, this can cause and move back the dimension difficulty.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned spinning method, a kind of production method of ramie siro spinning superfine yarns be provided, make the single thread fineness 100 public above, also can be directly used in woven ramie plied yarn.
In order to achieve the above object, technical scheme of the present invention provides a kind of production method of ramie siro spinning superfine yarns, it is characterized in that, concrete steps are: ramie rove and soluble vinylon fiber rove are adopted match network spinning method, on fine spining machine, mix in the drafting process, be spun into 100～300 public blended yarns, gained blended yarn plying, decorporate in water polyvinyl, washing and oven dry are made ramie high grade folded yarn.
In the described step with ramie rove and soluble vinylon fiber rove employing match network spinning method spinning blended yarn, the spacing of ramie rove and water soluble vinylon rove is preferably 0～14mm before mixing in the fine spining machine draw zone.
Water soluble vinylon content is preferably 10～70wt% in the described blended yarn, and ramie content is preferably 30～90wt%.
The described polyvinyl temperature of decorporating is preferably 40 ℃～100 ℃, and the polyvinyl time of decorporating is preferably 0.5～6 hour.
The preferred auxiliary agent that adds in the described polyvinyl process of decorporating.
Described auxiliary agent is preferably NaOH and JFC.
Described bake out temperature is preferably 50 ℃～100 ℃, and drying time is preferably 0.5～6 hour.
The fineness of described ramie high grade folded yarn is preferably 100/2～300/2 public.
Described blended yarn single twist multiplier is preferably 60～160, and the twist factor of ramie high grade folded yarn is preferably 60～180.
Beneficial effect of the present invention is as follows:
1. adopt the method for plying, promptly synthetic strand retreats dimension, solves for a long time because dissolving away of polyvinyl caused defective such as the short texture of yarn, brute force are low, bar evenness difference and can't carry out woven problem;
2. adopt the match network to spin at fine spining machine and realize the method that ramie and polyvinyl mix, yarn strength height, the bar evenness of spinning are good;
3. water soluble vinylon is short as the time that carrier fibre participates in spinning process, and technology is simple, and is very little to the influence of preceding road spinning process, and follow-up processing and sorting is not had influence;
4. because the similar strand of yarn formation structure that spins of match network, it is simple to move back dimension, and speed is fast and move back dimension rate height;
5. break through the limitation that low and middle-grade ramees can't high grade yarn, solved the low and middle-grade ramees that utilize that people always pursue and made the problem of a high expensive goods;
6. the height that is spun into props up strand and can be used for developing different structure, tissue, and has high widely thin thin woven fabric of certain density, Application Areas and knitted fabric;
7. the aqueous solution of water soluble vinylon belongs to the biodegradable product, and is biodegradable in the activated sludge that light water is handled, and environment is not had any public hazards, so the ramie high grade folded yarn of producing is a kind of product of green non-pollution.
8. technology is simple, the production efficiency height.
