For many printing, attention should be paid to printing when mass producing silk screen products, ribbon printing and ribbon printing. Screen printing is the basis of screen printing, and selecting appropriate screen is an indispensable link. As printing processing and screen printing have a very wide range of applications, there are many factors related to them. When selecting screen, different printing screens should be selected according to the specific situation and printing requirements. Generally, the following different perspectives can be considered when selecting screen. Screen shall be selected according to the type of substrate with binding ribbon printing and printing price. When selecting, it shall be selected and used according to fiber fabric, paper products, glass, ceramics, metal, plastic, wood products, electronic products, etc.
The progress of process technology has brought about the upgrading of edging webbing products. In 1979, the trial production of the domestic generation SD9-9 rubber ingot belt was successful, which ended the history of rubber ingot belt products relying on imports. 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.
In the 1970s, due to the promotion of continuous ribbon dyeing and ironing machine, Xiamen Selvedge webbing Manufacturer From the traditional process of dyeing before weaving to the continuous process of weaving before dyeing, weaving before bleaching, ironing after treatment, the ribbon technology has entered the ranks of mechanized mass production. In the early 1980s, the industry introduced high-speed shuttleless loom, ironing machine, wrapping machine, warping machine, etc. from Switzerland, Italy and the Federal Republic of Germany, and the ribbon technology entered a new stage of development. The progress of webbing technology has brought about the upgrading of products. In 1980, Customized Selvedge webbing Manufacturer The rubber ingot belt has the characteristics of soft, light, thin, firm, small elongation, small impact force, short and flat joints.
The tensile strength after light treatment, the natural light shines on the bag webbing through the window, causing aging and reducing its strength. According to the working conditions, a lighting equipment is designed, which is equipped with representative strong light and is exposed to the light for a specified time. After lighting, pp webbing needs to be subjected to standard temperature and humidity treatment, and then to tensile test to obtain the tensile strength after lighting treatment. After soaking, the tensile strength of the safety belt installed in the car will absorb the moisture in the air, and sometimes it will be soaked by some liquid, so the immersion test is required. At room temperature, fully immerse in distilled water with a small amount of wetting agent for a specified time, and then take out the soaked pp webbing from the water to complete the tensile test within 10 minutes. The tensile strength of soaked pp webbing was obtained.
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.
