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.
Liaoning Customized Single and double layer webbing Guess the pros and cons. It is difficult to identify the front and back sides of some cases and bags because of their special texture. The following is how the luggage and webbing factory teaches you to identify the front and back of the webbing. In fact, we can identify it according to the pattern of the webbing, the front of the pattern is clear and clean, the pattern lines are obvious, the layers are clear, and the color is bright. commonly Liaoning Customized Single and double layer webbing wholesale The patterns on the front are clearer and more beautiful than those on the back. The front pattern of plant and color matching patterned fabrics with striped appearance must be clear and pleasing. This pattern is especially obvious when weaving jacquard belts.
What are the characteristics of the edging webbing: moisture retention: because the pure cotton edging webbing is a poor conductor of heat and electricity, the heat conductivity coefficient is extremely low, and because the cotton webbing itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between the webbing, and the air is a bad conductor of heat and electricity, the pure cotton webbing has good moisture retention, and people feel warm when using the pure cotton webbing. Hygiene: pure cotton edging webbing is a natural fiber, which is mainly composed of cellulose, a small amount of waxy substances, nitrogen and pectin.
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 application of is already very common, and the technology is also new one by one. Let's talk about it briefly from the manufacturer's editor. I hope it can help. It is well known that it has been widely used. Now many bag webbing manufacturers are constantly upgrading their products to make our life more convenient. Knitting can not only weave belts, but also weave ropes. Tubular belt is a kind of braided rope. Rope or rope with a diameter of 1~4 cm is also called rope. Rope with a diameter of more than 4 cm is also called rope. Rope with a diameter of more than 40 cm is generally called cable or rope.
