Xiamen customized Single and double layer belt 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. customized Single and double layer belt wholesale 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.
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 moisture in the air may cause spots in the car. When this kind of webbing contacts the clothes of passengers, the spots and colors on the luggage webbing will also be transferred to the clothes. Therefore, it should have anti spot fading characteristics, which is also called spot color fastness. The spot color fastness test includes multi fiber test and filter paper test. The multi fiber test is to clamp a sample of tissue belt between two layers of colored cloth. Immerse the mixed colored cloth into the vessel with distilled water and completely wet it. Then squeeze the water out of the extruder, and then clamp these colored cloth wrapped with selvedge webbing into the plexiglass sheet, put it into the sample holder, and lock the sample holder. This rack is placed in a high and low temperature box at a certain temperature, and after reaching the specified time. Take out the sample and hang the colored cloth.
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 on the belt surface by naked eye, and the needle edge and cloth edge cannot be exchanged for the color and texture (the needle edge of each woven belt must be of one color). 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.
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: general accessories include metal clasps, certificate clips, etc., and plastic ones include aircraft clasps, plug buckles, safety buckles, 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.
