Surface fuzzing. The case and bag webbing surface fuzzing and needle edge defects often occur in the production process. What are the reasons and how to solve or prevent them? The following manufacturer's knitting will tell you. Causes of surface fuzzing of luggage webbing: needle edge fuzzing, cloth edge fuzzing. Precautions: The needle plate has been used for a long time and has been damaged. Replace the needle plate with a new one; The knitting needle has been damaged and replaced with a new one; The pressure plate is pressed too tightly, and loosen the pressure plate; If the weft is not hung completely, adjust the distance between the weft needle and the knitting needle so that the weft can be hung completely. The steel buckle of the weft yarn is hung, and the weft yarn is put into the weft rod; If the steel buckle is damaged, replace it with another one; The raw material itself is hairy. If it is partly hairy, replace it. If it is too hairy, make a full inspection belt after finishing the goods.
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.
The convex and concave convex fabrics are compact and delicate on the front, with strip or pattern convex patterns, and rough on the back, with long floating lines. Wool fabric: single side woolen fabric, with the pile side being the front side of the fabric. For double-sided fleece fabric, the front side shall be the smooth and tidy side. Observe the selvage of the fabric: if the selvage is smooth, the neat side is the front side of the fabric. For double-layer, multi-layer and multiple fabrics, if the warp and weft density of the front and the back is different, the front side has a larger density or the front side has better raw materials.
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;
Customized Glass cv webbing wholesale Ink printing. At first glance, ink is not very different from glue, but when glue is printed on smooth fabrics, such as wind clothing, the color fastness is generally poor, and it can be scraped off with a nail, but ink can overcome this shortcoming. Therefore, when making windbreaker, it is usually printed with ink, with bright color and vivid image. make well-connected Customized Glass cv webbing There has been a wave of head prints in the market some time ago~I don't know if you have noticed it, then the clear and ultra realistic printing can only be printed with ink in general~Sometimes you can sprinkle gold powder and silver powder on the ink, and feel that the decoration effect is better.
