special Cotton ribbon wholesale 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. Fushun special Cotton ribbon wholesale 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 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, it was all handmade workshops that produced exquisite pictures of ribbons. The raw materials were 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.
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.
The basic process flow of knitting is: bleaching and dyeing - weft rolling - weaving - off machine cutting - 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. In 1980, SD-81A and B rubber ingot belts were developed, which are soft, light, thin, firm, with small elongation, small impact force, short and flat joints. At the beginning of 1990, the trial production of car seat belts for Santana cars was successful. After more than two years of research and trial production, the product quality reached QC49-92 and TL-VW470 standards.
It may be due to the use of too much thinner, especially the poor compatibility of thinner and ink, which causes color bleeding during PP textile printing. It may be that there is color seeping on the edge of the printed image and text, which is a common phenomenon, so don't worry too much. It can be solved by ordinary methods. It may be caused by the selection of dyes in the ink, or it can be said that it is caused by the improper matching of pigments. We can deal with the problems in this link according to the situation, and pay attention to the details in this link.
At present, more than 90% of the market is made of cotton polyester thread or polyester cotton thread, but there are few pure cotton threads in the market, and the price is surprisingly high! Polyester cotton yarn just neutralizes the advantages of pure cotton and polyester, depending on the composition of polyester in cotton. Generally, the yarn of cotton ribbon is made by adding a small amount of polyester into cotton, so that it can have the advantages of pure cotton and polyester cotton. It is easy to wash, heat resistant, alkali resistant, moisturizing, sanitary, wear-resistant, not shrink, not easy to wrinkle, not easy to deform, not easy to stick wool, and so on! The key is that the proportion of cotton and polyester is appropriate! The identification method of pure cotton webbing and polyester cotton webbing is simply to take the cut thread and burn it. If there is any hard block, it is polyester cotton yarn containing polyester, and if it is completely reduced to ashes, it is authentic pure cotton.
