Gongzhuling Customized Braided rope The narrow Shenzhen ribbon or tubular fabric is made from various yarns. There are many kinds of belt fabrics, which are widely used in clothing, shoes, bags, industry, agriculture, military supplies, transportation and other industrial sectors. In the 1930s, Gongzhuling Customized Braided rope Manufacturer All are handmade workshops with exquisite pictures of webbing, and the raw materials are cotton thread and hemp thread. After the founding of the People's Republic of China, the raw materials for ribbon gradually developed to nylon, vinylon, polyester, polypropylene, spandex, viscose, etc., forming three major types of technology: weaving, knitting, knitting. The fabric structure includes plain weave, twill, satin, jacquard, double-layer, multi-layer, tubular and combined weave.
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.
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. 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;
According to the functional data learned by Xiao Bian, the temperature of the lit cigarette is about 700 ℃, and the continuous burning time of a cigarette is about 15 minutes, which is a long time. However, the spontaneous ignition point of common combustibles is very low, such as paper, cotton, linen and knitted fabrics, whose ignition point is mostly 200 ℃ to 300 ℃, so it is easy to cause fire. Turning to the statistics of major and catastrophic fires nationwide, there are many records of fires and casualty accidents caused by smoking after drinking, smoking in bed, littering cigarette butts and other reasons. The typical case is the Great Khingan Mountains forest fire in 1987, which caused a heavy loss of 6.913 billion yuan. It was later discovered that four of the first five fire spots of the fire were caused by human beings, and two of the fire spots were ignited by the cigarette butts of three "smokers".
As an industrial product, it also has its own standard service life, which determines the length of our actual use of webbing. Generally, there are two kinds of situations at the end of use. One is the problem of quality or external damage within the service life, so it can no longer be used. The other is the problem of natural wear and fracture, which is natural damage. It is also inevitable. Today we will talk about the life span in detail. How long is the life span?
