After the weft tube is formed by the yarn warp cylinder and weft winding, it is inserted on the fixed gear seat of the knitting machine, and the weft tube rotates along the 8-shaped track to draw the yarns to cross weave with each other. Usually, the number of spindles is even, the woven tape is tubular, the number of spindles is odd, and the woven tape is flat. Spindle weaving technology has been applied since old China. The number of spindles varies from 9 to 100 due to different equipment. The basic process of weaving is: bleaching and dyeing - weft rolling - weaving - off machine shearing - packaging. Since 1960, many technical innovations have been carried out on the knitting machine, mainly including the enlargement of peach plate diameter, the installation of an automatic stop device for breaking rubber bands, and the replacement of iron ingots with nylon ingots. The improvement of these equipment has increased the vehicle speed to 160~190 rpm, doubled the stand rate and greatly improved the product quality.
Direct dyes, suitable for cellulosic fabrics, have poor washing fastness and different light fastness, but the modified direct dyes will improve their washing color. Disperse dyes are suitable for viscose, acrylic, nylon, polyester, etc. The fastness to washing is different, polyester is better, and viscose is worse. Azo fuel (Naftol dye) is suitable for cellulosic fabrics. It has beautiful color and is more suitable for beautiful color and luster. Sulfide dyes are suitable, with dim color, mainly dark blue, black and brown, good light resistance and water washing resistance, and poor chlorine bleaching resistance. Long term storage of fabrics will damage fibers.
It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, we can directly wrap a unique garment with silk scarves in the hot summer, which is not only beautiful but also comfortable. Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation is proud of its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a large amount of air in these gaps, which prevents the heat emission and makes the silk have good warmth retention.
