The longitude and latitude are interwoven. Xiamen special [Subject wholesale 】After twisting, the yarn is warped into a package (pan head), and the weft yarn is shaken into a bobbin, which is woven on the loom. In the 1930s, it was used for hand looms and iron wood looms. In the early 1960s, the 1511 loom was converted into a belt loom, which is still widely used. Due to the small width of the belt, the weaving methods are different, ranging from single, double, dozens of pieces, from single layer to double layer. In 1967, Xiamen special Electrical tape The research group of shuttleless weaving belt with workers as the main body in the industry has successfully designed and manufactured a high-speed single shuttleless weaving belt machine by itself, realizing that the weaving belt does not need shuttles, and the process is shortened, the floor area is small, and the labor productivity is improved, which is an innovation in the history of Chinese weaving belt technology.
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. Under normal temperature, 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.
What are the characteristics of the edging webbing: moisture retention: because the pure cotton edging webbing is a poor conductor of heat and electricity, the heat conductivity coefficient is extremely low, and because the cotton webbing itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is a bad conductor of heat and electricity, the pure cotton webbing has good moisture retention, and people feel warm when using the pure cotton webbing. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
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.
