special Single and double layer webbing Manufacturer Not only the production process is complex, but also the packaging process is very complicated. Only the webbing that has passed the inspection can be packaged out of the warehouse, otherwise it will be treated as defective products. Fuzhou special Single and double layer webbing Manufacturer The specific packaging process is as follows: 1. The process control method: 1. The surface of each winding tape must be smooth and flat (except for special webbing); Those who cannot be involved in substandard products shall be held accountable according to the seriousness of the case. Knot: ≤ 3/100Y, ≤ 2/50Y; Short code: ± 0.5/100Y; Each knapsack strap must have the label of the tape coiler. Inspection according to the customer's requirements: for example, 336, 217, 115, 314, 108, 114, 384, 206, 419, 122 adhesive paper and rubber hose, no pins can be used;
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.
The longitude and latitude are interwoven. [Subject] After twisting, the yarn is warped into a bobbin (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, the research group of shuttleless weaving belt with workers as the main body in the industry successfully designed and manufactured a high-speed single shuttleless loom by itself, which realized 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.
Silk fabrics have high porosity, so they have good sound absorption, dust absorption and heat resistance. Therefore, in addition to making clothes, it can also be used for interior decoration, such as silk carpets, tapestries, curtains, wall coverings, etc. Decorating a room with silk ornaments can not only make the room spotless, but also keep the room quiet. Due to its hygroscopicity, moisture release performance, moisture retention, air absorption and porosity, it can also adjust the indoor temperature and humidity. Silk fiber has small thermal denaturation and is relatively heat-resistant. When it is heated to 100 ℃, it is only about 5-8% brittle, and the thermal variability of most synthetic fibers is 4-5 times greater than that of silk. The combustion temperature of silk is 300~400 ℃, which is a non combustible fiber, while the combustion temperature of synthetic fiber is 200~2600C, which is flammable and fusible. Therefore, using silk fiber as the raw material for interior decoration can not only play the role of sound absorption, dust absorption, heat preservation, but also play the role of flame retardant.
