Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to a technical field of latitude braid, especially a technical field of apparatus for producing of hollow platykurtic elasticity latitude braid.
[ background of the invention ]
The knitting and weaving is a technological process of forming loops by using crochet needles on yarns or filaments of different raw materials and varieties and then connecting the loops into knitted fabrics through stringing. The knitted fabric is soft in texture, has good wrinkle resistance and air permeability, has good extensibility and elasticity, and is comfortable to wear. In the case of the integral molding process, a knitted fabric woven by a circular machine tends to be circular. Due to the internal stress of the fiber and the twisting of the yarn during stretching, unwinding or weaving, the fabric has poor shape retention after being stretched, especially poor dry uniformity and difficult flatness maintenance. Therefore, when such products are used as elastic ear bands for masks, there are drawbacks in that the appearance and wearing comfort are poor.
In the processing of textile chemical fibers and fabric formation, setting refers to a process of stabilizing the form of a formed fiber, yarn or fabric mainly by external conditions. For conventional chemical fibers and yarns and fabrics thereof, the glass transition temperature is generally low, so that molecular motion in the fibers can be accelerated by using proper high temperature, and the distribution of amorphous regions in the materials is improved. The good heat setting condition can eliminate the internal stress of the fiber and the wrinkles on the surface of the fabric, and improve the overall dimensional stability of the fabric or the yarn, thereby improving the strength, the elasticity, the hand feeling, the yarn evenness and the pilling performance of the fabric or the yarn. The application of the heat setting technology in the spinning and texturing process of chemical fiber is mature and stable, for example, the invention patent CN201511025553.3 'a process for yarn steam heat setting treatment' discloses a form of utilizing continuous steam heating and oil auxiliary heating, which improves the heat setting quality of yarn, but the process is an off-line step-by-step process, the required setting time is 30-90 s, the continuous on-line operation is difficult to realize, and the production efficiency is low; the invention patent CN201210505838.7 'a heating roller heat setting processing device', the utility model patent CN201320755864.5 'a heat setting component' discloses a heat setting processing device utilizing a heating roller, which improves the heat setting effect of a diaphragm, thereby solving the problem of shaking in the winding of the diaphragm, but the heating roller is suitable for a film material rather than a fluffy elastic fabric, and the pressure and the high temperature of the heating roller can change the appearance of yarns or fibers in the fabric, thereby affecting the performances of the whole elasticity and the like.
