Uses: for quilts, sleeping bags, jackets luggage, handbags, sofa, filter materials, speakers sound-absorbing cotton, cotton filter material bust, furniture cushions blankets, shockproof materials, shoes and so on. According to the process were: spray and spray soft pulp slurry hard points, also known as a shotcrete Spewing floss, non-woven cloth, principles Spewing structure formation is to spray adhesive on both sides of the fluffy fiber layer , due to a certain pressure during spraying, and the lower portion of the vacuum suction when the liquid, so the inside of the fiber layer also can penetrate into the adhesive, spray adhesive, after the fibrous layer and then after drying, curing, the fibers intersection between being bonded, and not bonded fiber, there is still a considerable degree of freedom, while in the three-dimensional network structure, still retains many of tolerance air gap, therefore, has a porous fibrous layer , the thermal effect of high bulkiness, due Spewing is the case in the spray, instead of adding a binder in the immersed condition, and no longer subject to the pressure in the spray after extrusion and curing, therefore, the fiber bonding state, the cross-point contact of the majority, but by less adhesive bridge agglomeration. This is Spewing to keep loose, soft, warm the main reason. According Spewing structure formation principle, in order to be able to get together Spewing excellent physical and mechanical properties to be studied in the selection and choice of the fiber material and a binder and production processes, in which the fiber raw material selection is particularly important . 2 Spewing Products Spewing were: spray soft cotton, plus hard Spewing, washing cotton, black bag Spewing, white glue Zhenmian, Spewing role and coating as follows: fiber material The types and specifications for quality Spewing products play a decisive role, according to the requirements Spewing taking warm and good, fluffy and good, soft features, must denier fiber length, curl in, cross-sectional shape and surface treatment status performed well chosen. As we all know, the quality of synthetic fibers are composed of many performance indicators together decision. Includes physical, mechanical indicators. Stable performance and processing performance of the three categories, for different production processes, requiring its quality indicators is not identical to the fibers used Spewing terms require fine denier fibers, the number of crimps and curl high fiber cohesion between each other better. Thus, the bulk of the product, the compression elastic recovery rate was also high, at the beginning of a three-dimensional spiral curl curl better. Bulkiness and elastic recovery rate of their products significantly better than the same product plane waves curl, hollow rate can give the product a higher rate and a lower proportion of warmth, spin finish oil content types and fiber , moisture regain level not only affects the processing performance, while improving the feel of elimination products, the production process also play an important role in the phenomenon of static electricity, fineness conventional polyester hollow helical crimp of 6.6-7.7 dtex (eltex) of length 51 -76 mm. This specification of the fiber, its overall performance is better, the fibers are too thin or too long, it will produce very soft and not feel too short too thick then they feel stiff, three-dimensional spiral curl curl better places, common number of crimps 0.5 to 0.6 pieces / mm, such as using a round hollow fibers, hollow degree is preferably 5-10%, its feel, flexibility and warmth can be greatly improved, while the amount of fibers can be reduced accordingly, in the conventional polyester mixed with 30-70% down fiber to produce imitation imitation down Spewing, called imitation feather fiber is actually a three-dimensional hollow polyester fiber after silicone oil processing characteristics of this fiber is soft, supple fibers to each other is not tangles, fluffy and good, therefore, to make the product can reach the elastic is loose feel smooth and slippery, with the characteristics of down. 3 Spewing product comparison Spewing several points: the white hot glue cotton, plus hard Spewing, washing cotton, soft cotton, Spewing blue, black Spewing, glue Zhenmian. Spewing is no color white odorless, environmentally friendly role. Hard Spewing Cadogan some hard pulp on the basis of the original ordinary Spewing glue made. Black, blue Spewing just raw materials to change color, as long as our customers with color card can do colored Spewing. First you have done after the glue Zhenmian on Zhenmian machine, and then glue. Just spray and soft soft pulp, pulp washing cotton soft and need to spray Tangmian treated fiber materials used for the fine material can make the product will feel good. This product is suitable for clothes, cotton quilts and other bedding.
