Detailed description of the invention
For Development and Production goes out the key product of oneself, to walk before market, leader's new trend of weaving, produces highly difficultHigh-quality product, obtains abundant economy return. For client's demand, more develop the leading weaving row of oneself for companyThe key product of industry, starts to drop into manpower and materials in June, 2013, carries out relevant research, up to now, purchases20 tons of MicmodalAir raw materials, pilot development more than 50 time, has changed breast swift, doffer, flat-clothing, and has changed combFitting Fixed Flat Plate before and after cotton machine, has designed and has customized relevant drawing-off wheel and the viscosity wheel of spinning frame, according to technology Calculation, has customizedThe little roller of compact spinning, diameter is 19.1, has bought unconventional 35mm rings and 18/0-26/0 wire loop, finally works outProduce the production technology that 140 Ying Zhi-220 English prop up, and form batch production, relevant fabric is produced in batches three producers,Fabric is more frivolous, elegant and poised, touches cloth cover just as touching baby's skin, sliding glutinous softness, and comfortable incomparable, fabric weight canWith below 80 grams, even through repeatedly washing repeatedly, it is perfect soft that fabric still keeps. The height of ultra-fine modal yarn linear system rowZhi Gaomi plain weave, Double-face fabric, the popularization as high value added product on market, has obtained the accreditation of high-end customer.
This production technology adopts following technology path. The pretreatment of raw material row dish and raw material (adds water, adds antistatic additive, addsObvolvent agent) → utilize (FA002A disc bale plucker) to capture the mixing shredding (ZFA036 mixed cotton slitter) → enter of raw material → raw materialStep mixing shredding (FA022-6 multi-mixer) → further shredding (ZF1102A card wire opener) → directly get again by horizontal pavingInferior mixing is also evenly fed to (FA046A vibrating cotton box cotton feeding) → make lap (FA141A single beater scutcher) → be carded toWeb is also made sliver (longitude and latitude FA224D carding machine) → drawing-off, and and (longitude and latitude frame JWF1310 drawing frame) → further leadStretch, and and (Switzerland Rieter RSB-D22C drawing frame) → drawing-off, twisting, coiling, moulding (the global FA497 fly frame in Qingdao) → enterOne step drawing-off, twisting, coiling, moulding (longitude and latitude frame JWF1510 spinning frame+with and compact spinning) → further remove fault, volumeWinding forming becomes cylinder yarn (Italian SAVIOPOLARL type bobbin-winding machine).
