Description
Technical field
The present invention relates to a kind of online pre-processing device that improves yarn sizing performance that uses on Sizing machines, belong to textile machine equipment.
Background technology
Sizing is an important procedure in the woven industry, although be a preparatory process, but good sizing can reduce the warp end break in the weaving process in a large number, and good destarch operation, what help dyeing carries out smoothly, therefore factory generally be summarized as " starched yarn with regard to solved the problem of weaving 70% ", the importance of sizing preparatory process can be described.From knitting portion's coordinative composition of equipments, a Sizing machines will be supplied 300 left and right sides looms, from the angle of producing, sizing was produced one minute, class of loom running, so the quality of sizing quality realize that to weaving process high yield, high-quality, low consumption have extremely close relation.And the quality of woven grey cloth destarch performance, the effect of also directly influence printing and dyeing, back arrangement.
PVA is a polyvinyl alcohol, is a kind of typical water-soluble synthetic macromolecular compound.It is to be got by the methyl alcohol alcoholysis by vinyl acetate.PVA is widely used in various fabrics with its good sizing performance, especially high-count and high-density fabric, present global PVA annual consumption is about 100,000 tons, and continuous increase along with high-speed weaving machine, highly dense type of textile article is continually developed, and a large amount of uses of various new fibers, also more and more high to the requirement of warp sizing quality, the use amount of PVA is also more and more.But PVA in use also shows fatal defective, and more and more is subject to people's attention, and the cry that uses no or little PVA is more and more higher.Be in particular in: the difficulty of 1, sizing mixing.By conventional in the world, the alcoholysis degree that is used for the complete alcoholysis PVA of warp sizing should be DH=98 ± 1mol%, is hot water solubility's (80-85 ℃).But what supply on the China market 1799 is (fibre-grade) that is used for spinning mostly, its DH 〉=99.6mol%.This causes its water-soluble deterioration, even needs ability dissolving in high-temperature boiling 2-3 hour, and not only energy consumption is big in the mashing off process, and brings very big difficulty for textile mills' size mixing equipment.2, warp sizing, the grey cloth destarch, PVA has brought very big difficulty for printing and dyeing mill's pre-treatment.Printing and dyeing mill requires to move back clean rate and reaches more than 95%, not only consumes a large amount of water, steam, chemical materials.And the residue of PVA still influences the impregnability and the level-dyeing property of dyeing, stamp, and directly influences dyefastness.This is because remain in slurry on the fabric, has very strong and the ability dyestuff reaction equally, makes dyestuff and fiber in conjunction with not tight, comes off together during washing.Destarch is also influence " three anti-" " four is anti-" arrangement quality only, and in sorted material and fibrin reaction, a part also can react with slurry, thereby influences the durability of wrinkle resistant, waterproof, oil resistant finish and functional.Because the easy coherency of PVA is built-up in and forms spot on the fabric, not only causes a large amount of substandard products, exports to foreign countries and also can detect the vestige of PVA.3, be difficult to degraded, influence environment.PVA desized wastewater BOD, COD value reach 16800,1800 respectively, and very difficult biodegradation (more than 900 days).Because seriously polluted, developed countries such as the U.S., Japan, European Union set up technical standard one after another, and the use of restriction PVA slurry in sizing is to the fabric limiting inlet of PVA starching.4, price is more expensive, and common PVA price is higher than the starch based slurry far away about 1.3 ten thousand yuan.
Along with the international trade environment green barrier is strengthened day by day, domestic also put into effect successively a series of requirements such as " ecological textile specification requirement ", " textiles technical specification of security ", " textile industry prevention and cure of pollution planning " use less, without the policies and regulations of PVA starching.Research in this respect at present both at home and abroad is mainly from the angle of the substitute of PVA, promptly by research high-performance slurry, to substitute the use of PVA, the DY265 that produces with Jiangxi Dongyong Industrial Co. Ltd. in these researchs, the biochemical slurry of DY269 polyester, the ASP that Holland Ai Weibei company produces, the E219 transgenosis starch that Germany Yi Aisi associating group produces, the PENFL EX graft starch that U.S. Process Chemical L.L.C produces, the AD that the clean beautiful company in Suzhou produces, Qili Assistant Co., Ltd., Shanghai produces the OLG acrylic size, CD218 half combined slurries that Shanghai C﹠D Industrial Co., Ltd.'s dirt produces etc. are representative.But which kind of substitute products no matter, just part substitutes, and be not easy to replace fully, and these alternative slurries also can produce new pollution in process, and processing and use cost are higher simultaneously.
Summary of the invention
At the problems referred to above, the objective of the invention is to propose a kind of on Sizing machines the online pre-processing device that improves yarn sizing performance, by pre-processing device yarn is carried out certain preliminary treatment before entering stock tank, change the yam surface structure, improve surface polarity, to improve the absorption property of yarn, reach the purpose that replaces PVA with the common starch slurry to common starch class slurry.
Its technical solution is as follows:
Pre-processing device is by casing, deflector roll, the electrion head, ozone generator, ultraviolet irradiation device and sealing rubber roll are formed, the sealing rubber roll is fixedly mounted on two of casing respectively in opposite directions on the tank wall, the two ends that are installed in the deflector roll in the casing are fixedly mounted on respectively on two sidewalls of casing, be fixedly mounted on corresponding with the deflector roll respectively installation of electrion head in the casing, gap between electrion head and the deflector roll forms the passage of yarn operation respectively, ultraviolet irradiation dress stomach is fixedly mounted between deflector roll and the sealing rubber roll, its two ends are separately fixed on two sidewalls of casing, ozone generator is fixedly mounted in the casing, is provided with the passage that has open-close on-off above casing.The operating voltage 8.0-20.0 of electrion head does volt, and the ultraviolet waves wavelength of ultraviolet irradiation device is 200-290nm, and ozone concentration is 5-10ppm in the casing, and pre-processing device is installed between the warp beam and stock tank part of Sizing machines.
Owing to adopted the technical program, pre-processing device of the present invention is by carrying out preliminary treatment to yarn before entering stock tank, change its surface texture, improve surface polarity,, reach few usefulness and without the purpose of PVA slurry to improve the sizing performance of yarn to the starch based slurry.After using this pretreatment unit, do not using fully or reducing significantly under the operating position of PVA slurry, using the common starch slurry just can obtain good starch finishing effect, the yarn of institute's starching is also owing to not using PVA and good hand touch, destarch performance are good.The present invention simultaneously also has and drops into lowly, and operating cost is low, the advantage that does not cause any environmental pollution and increase chemicals.
