        cylinder yarn steaming machine that our company produces the vacuum
yarn yarn steaming machine, can provide a very cost-effective way to improve the yarn quality. The machine can heat setting the yarn. For the wet treatment, uniform infiltration, preheating type steam yarn increased cotton yarn weight up to 1.7%-... 3%, increase the yarn weight up to 2.4%--  4%.   J40s tube yarn, yarn steaming hairiness changes before and after the table   before the yarn steaming steamed yarn     root /10m (2mm)   /10m (3mm)   root; root /10m (2mm)   /10m (3mm)   root; 158.5  39  134.8  31.5  moisture regain:   7.22%  11.02%  moisture regain rate: two,   energy saving and environmental protection steamer advantage:   1 short process time, save energy, compared with the traditional yarn steaming machine, energy saving up to 80%.   2 quality is stable, precise control of temperature, humidity so that each production lot to get equal treatment.   3, investment recovery period is short, lower than the import equipment investment cost, obvious energy saving than domestic equipment.   4 no shock treatment, no condensed spots.   5 can regulate the temperature, and can adjust the humidity.   6 for handling trolley, pallet loading yarn.   7 can handle all kinds of natural and synthetic fiber yarn, blended yarn.   three,   yarn heat setting   1 Typical yarn steaming process step   vacuum preheating humidifying insulation --. Constant temperature -   vacuum cooling end   2 unique preheating system of   in the yarn steaming process, on the yarn water pearl spot is a common problems, water spots may cause staining and other problems, after the procedure so that the yarn steaming preheating process is absolutely necessary, especially wool yarn.     heat setting 3 yarn; each production process (spinning, twisting, weaving...... ) will cause tension effect yarn and fiber, tension will cause the tangled yarn. The tension and the entanglement will bring problems after the procedure, and the artificial fiber molecular structure stress relaxation to fiber shrinkage, therefore, has brought the best choice of astute machinery produces the yarn steaming machine for the production of yarn.   research shows that the following kinds of yarn must be relaxed and setting using the steamed yarn: cotton yarn, wool yarn, polyester cotton blended yarn, polyester yarn, Bao Xinsha (spandex), sewing thread, rayon yarn, acrylic tow, mesh knitted fabric (crimped fiber).   each raw material needs special processing technique to achieve the ideal effect, the temperature range from 50 DEG C to the highest   140 C (see table   1). Saturated steam is the most ideal thermosetting medium, it is easy to penetrate to the tube gauze, and condenses the release of energy. When the yarn is heated to a specified temperature, the temperature difference is maintained in the range is very small in.   table yarn of various raw materials l best yarn steaming temperature range of     four, yarn; humidification; in the production process of yarn, fiber moisture volatilizes ceaselessly, from raw material to the package, the humidity accumulated reduction of more than   4%, therefore, humidifying treatment of yarn has become an important part of modern textile technology. It can compensate the yarn weight loss and improve the quality of yarn. Spinning factory different have different yarn humidity index, improve the speed of the machine may lead to greater weight loss (water). Inside the machine high temperature and friction will evaporate the moisture inside and reduce yarn, yarn quality, is not conducive to the processing way, and the humidifying treatment can solve this kind of problem. Table 2 for cotton yarn of different production processes of humidity.   table 2 cotton yarn in different production process humidity  %  humidification treatment of yarn (yarn steaming) located after winding, yarn storage before, if the storage time is longer and the yarn in the delivery before as well. In addition, knitted and woven can also benefit from the use of yarn humidification treatment before (Zheng Sha). Transport packaging such as yarn appropriate tube line bagged or yarn tension winding disc seal packaging can keep the humidity of yarn.   research on the weaving of the show, the yarn through humidification after treatment is better than without humidification treatment (dry yarn). When using the warp threads of humidification treatment to make the weft weaving, cloth machine stop number will be greatly reduced. In addition, strength and elongation at break of yarn is improved and the hairiness is reduced, thus improving the weaving efficiency of 2%, in the knitting see flyings wool dust significantly reduced.   in the trade, the buyer will not accept additional markup, increasing yarn weight is the increase in profit. In general, the yarn humidifying treatment equipment investment return period is less than 1 years, and the cotton yarn of the humidification equipment investment return period and even less than half a year. In addition, the requirement on the quality of export trade, also need to continuously improve the quality of the yarn. Therefore, the yarn wetting treatment has become an important part of the textile process.   five,   removal efficiency of 1 relaxation, amorphous, humidification.   2 to increase yarn strength, reduce the fracture (cotton yarn breaking strength will increase 10%, yarn breaking elongation increased 30%).   3 cotton yarn hairiness fallen petal dust reduce 30-45%.   4 yarn humidity uniformity, high precision control of moisture regain.   5 to eliminate static electricity, improving yarn unwinding effect.   6 soft touch.   7 to improve the color effect.   8, improve production efficiency, improve the comprehensive quality of products.   six, to the finishing process of knitted   benefits of   1; (1) the unwinding tension of yarn, efficiency increased up to   20%; (2) soft yarns, reduce needle wear;   (3) from start to roll forming, and always maintain the friction equilibrium and optimal value; (4) the knitting process, coil forming uniform; (5) the size stability of finished product; (6) without additional humidification system; (7)   to eliminate static electricity.   2 woven   (1) broken yarn is reduced up to 15%; (2) reduced lint and fiber fly 30-45%, improve quality;   (3) improve yarn strength, improve weaving efficiency; (4) the fabric more soft.   3 twisting / warping   humidity and twist setting completed in a single step.
