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.
Computer drawing process. Many friends are particularly interested in computers. Xiao Bian has briefly introduced the textile technology of computer jacquard belts before, but many people are still interested in how to draw computer jacquard belts. Today, we will introduce its drawing method according to the drawing process of the ribbon. Single color change: change the color of the left or right mouse button in the picture according to the position within the parameter range, and change the color of a connected color block within the parameter range. The color changed depends on whether the left or right mouse button is pressed. Select a rectangular range: click two points in the editing area to form a rectangular range with these two points as the opposite corners, so that you can clear, cut, copy, and organize this rectangular range. Clear out of parameter drawings: Clear the drawings outside the set range of longitude and latitude.
Heilongjiang Customized Selvedge webbing Width detection: the tolerance of webbing with width of 1 "and above shall not exceed ± 0.25 points; The tolerance of webbing with width of 25MM and above shall not exceed ± 0.5MM; The standard tolerance of webbing width of 1 "and less than 25MM shall not exceed ± 0.25MM; Note: The flat end and herringbone edging webbing must be of sufficient size, but not more than 0.25 points. Thickness inspection: the tolerance shall not exceed ± 0.1MM; Color difference test: there is no yin and yang color, color and texture on the belt surface by naked eye (each needle edge of the ribbon must be of one color) Customized Selvedge webbing Manufacturer The needle edge and cloth edge cannot be exchanged. Singeing and labeling: Each bag ribbon must be singed thoroughly, but cannot be burnt. The quality inspector shall inspect the packaging label to be consistent with the actual goods (specification, color, quantity), and seal it for warehousing. If errors and omissions are found, the relevant processes shall be traced in time, and the relevant personnel shall be held accountable according to the seriousness of the case.
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. Generally, 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.
One of the complete knowledge of printing types. There are many kinds of bag ribbon printing. Today, it is divided into two parts for everyone to talk about. If you like it, you can have a detailed look. It should be helpful to you. Here is the first part. Bag webbing transfer printing. The pigment is printed on the paper by printing method to make transfer printing paper, and then the color is transferred to the fabric by high temperature (heating and pressing on the back of the paper). It is generally used for chemical fiber fabrics, characterized by bright colors, fine layers, lifelike patterns, and strong artistry. However, this process is currently only applicable to a few synthetic fibers such as polyester. Transfer printing process is simple, investment is small and production is flexible. It is popular in the market at present But to be honest, compared with other types of printing, the price of this transfer printing is a little high, but it has a certain level.
