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.
It is precisely because of this performance that silk fabrics are more suitable for direct contact with human skin. Therefore, we can directly wrap a unique garment with silk scarves in the hot summer, which is not only beautiful but also comfortable. Silk not only has good heat dissipation performance, but also has good warmth retention. Its thermal insulation is proud of its porous fiber structure. There are many tiny fibers in a silk fiber, and these tiny fibers are composed of even smaller fibers. Therefore, more than 38% of the seemingly solid silk is actually hollow, and there is a large amount of air in these gaps, which prevents the heat emission and makes the silk have good warmth retention.
Customized Electrical tape Manufacturer If the weft needle is damaged, replace it or beat it with gauze; If the steel buckle is damaged, hit it with gauze or replace the steel buckle; The coir filament piece is damaged or the shutdown piece is damaged. Replace it with a new one. Causes of poor needle edge: uneven weft yarn thickness; The knitting needle is not properly laid, too long or too short; The pan head moves abnormally, sometimes tight, sometimes loose; The weft wheel is not round enough and deformed; The fixing pin of knitting needle is worn; Precautions: change another weft yarn; Heilongjiang Customized Electrical tape The knitting needle is longer or shorter according to the thickness of the ribbon. Generally speaking, the length of the knitting needle is just enough to remove the weft; Fix both sides of the pan head firmly, and do not let the pan head lean against the iron frame on both sides; Replace the weft wheel with a new one; Replace the fixed rod or go to processing.
What type is this? For example: ribbon, plaid belt, jacquard webbing, cotton belt and other products, these should be distinguished first. What is the size? The width and thickness should be understood clearly. What material is this ribbon? Different materials mean different prices. What color is it? How many colors are there? This also needs to be made clear. For example, single color ribbons should be cheaper, while multi color ribbons must be more expensive. Do you need dyeing? Some ribbons are dyed by the customer, and the price of dyeing is different.
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;
