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.
However, due to its hardness, it is not suitable for large area of field patterns. Large area patterns should be printed with water slurry and then dotted with glue slurry, which can not only solve the problem of hard glue in large area, but also highlight the sense of hierarchy of patterns; Another method is to steal a large area of field patterns and make them look bad, but they are always hard to wear. Therefore, it is better to combine water and glue to solve the problem of large area printing. It has smooth surface and matte surface. It has soft, thin, environmental protection and other characteristics, and can be stretched. Generally speaking, glue printing is more commonly used. For leisure brands such as "Yichun", they basically use glue ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡.
Liaoning special Shuttleless webbing Comfortable. Silk is composed of protein fiber, which has good biocompatibility with human body. In addition, its surface is smooth, and its friction stimulation coefficient to human body is low among all kinds of fibers, only 7.4%. Therefore, it follows the curve of the human body with its supple texture. 2、 Good moisture absorption and desorption. Silk protein fiber is rich in many hydrophilic groups such as amino group (- CHNH), amino group (- NH2), and because of its porosity, it is easy for water molecules to diffuse, so it can absorb or emit water in the air, and maintain a certain amount of water. At normal temperature, special Shuttleless webbing manufactor It can help the skin to retain a certain amount of moisture, so as not to make the skin too dry; Wearing it in summer can quickly dissipate sweat and heat from human body, making people feel cool.
Indirect plate making method: the indirect film is first exposed, hardened with 1.2% H2O2, developed with warm water, and dried to make a strippable graphic negative. During plate making, the adhesive film surface of the graphic negative is closely attached to the stretched screen, the adhesive film is tightly attached to the wet screen by extrusion, the film base is removed, and the screen is dried by wind. Process flow: 1. Stretched wire mesh - degreasing - drying. 2 Indirect film - exposure - hardening - development - fitting - drying - revision - blocking. 3 Straight mixed plate making method: first, paste the photosensitive adhesive layer on the screen frame with water, alcohol or photosensitive adhesive, dry it with hot air, remove the substrate of the photosensitive film, and then print the plate. After developing, the screen plate is made.
