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.
Cotton ribbon Manufacturer Here are some examples of the production process of radio lanyard, toy lanyard, flashlight lanyard and camera lanyard. 1. Wholesale of webbing: nylon, pp, polyester and high elastic cotton are generally used to make lanyards, and the general specifications are 4mm, 5mm, 6mm, 7mm, 8mm, 10mm, 12mm, 16mm, 20mm and 25mm wide. 2. Accessories: universal Changchun Customized Cotton ribbon The accessories include metal clasps, certificate clips, etc., while the plastic ones include aircraft clasps, plug-in clasps, safety clasps, etc. 3. Assembly: first print, cut according to the specified size, add string, plastic buckle, glue or press metal sheet, and then package. After inspection, a lanyard can be shipped in this way.
How much does a yard weigh? This is for accurate quotation. If you calculate the weight of one yard, you can know how much material is used for this yard of webbing. Is it single-sided or double-sided? Some are divided into single side and double side, so this should also be asked clearly. There are pictures for reference. This is to give us a visual judgment of what is, and give us a more accurate factor of quotation. How many are there? This is a matter of deciding whether to give customers a discount. If there is a large quantity, there must be a discount. Combine factors such as the wages of the factory, the master and the workers.
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?
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;
Causes of bleeding. Some customers will customize the printing, but the PP fabric manufacturers sometimes have color bleeding when printing the PP ribbon, so the manufacturers should pay attention to the reasons when printing. Only by understanding these reasons can we reduce the occurrence of various conditions in the future use. What are the reasons for color bleeding when printing? There is dirt on the surface of the machine during printing. Cleaning up during production can reduce these problems.
