1. Nylon fabric
1. Setting temperature: 160℃-180℃. Speed: 20M-25M/min.
2. The setting temperature changes greatly in color, especially purple, pink blue, etc., so pay attention to whether the color after setting is the same as that before setting.
3. The thickness and shrinkage rate of nylon fabrics are also different.
4. Nylon fabrics are easy to hook when setting. If there is a thread hooking all the way through the shaping, stop the machine immediately, check the machine head and tail, bellows, and drum, and polish with sandpaper or pad. (Such as stockings cloth, mesh cloth)
2. Polyester cloth shaping
1. Setting temperature: 170℃-200℃, speed: 20M-28M/min
2. The setting temperature of polyester generally does not change much, but the sublimation fastness of red dye is not good. The dye will be left on the machine after the process is completed. Light colors cannot be made immediately, only black. You can also use scrap cloth to make a few more Only after the second machine can you make light colors.
3. The shrinkage rate of polyester stretch fabric is very large. If the customer requires good elasticity, small shrinkage and good hand feel, the blank fabric must be pre-determined, paying special attention to the black and white. For red and white flowers, due to the poor sublimation fastness of the dye, the finished product must be set at a low temperature. If the temperature is high, the product will be seriously stained.
4. When shaping the polyester poppy fabric, pay attention to the thickness of the center and edges of the fabric. The temperature must be well controlled and not too high. Slow down the machine speed and pull in two steps. Setting it in two steps can reduce the difference in thickness between the middle and the edges. The first time you set it, the door width will be about 6-8 inches smaller than the finished product, and the gram weight will be about 100g. The temperature for the second time is 5-10 degrees lower than the first time, and the door width and weight are as required.
3. Cotton rayon
1. Setting temperature: 160℃-190℃, speed: 20M-30M/min
2. If cotton is dyed with direct dyes, the color of the gray fabric will change greatly when hot and cold. You must wait until the gray fabric is completely cooled before color matching. The active material will not change much.
3. Rayon is prone to aging at high temperatures, and burnt fabric is prone to snagging and tearing.
4. The shrinkage rate of cotton is very large. When setting the shape, the cloth feeding tension should be reduced, the pressing pressure should be increased, and the cloth should be pressed dry. The hot air blower should be turned to high and the machine speed should be slowed down to reduce the shrinkage rate. If If customer requirements are high, the test must be scaled back.
5. If the customer requires that the fabric surface does not have twists, it must be shaped in a twill pattern.
IV. Silk shaping
1. Setting temperature: 100℃-120℃, speed: 20M-30M/min
2. Turn down the hot air for silk shaping and make the door width smooth.
3. Silk is relatively delicate. Do not get water or sweat when styling, and do not use too much force when pulling the cloth.
Five. Fixed PU glue
1. Imported pulp, no discoloration at high temperatures, 140℃-180℃. Speed 25M-30M//min, large smoke.
2. Domestic pulp is easy to change color at high temperatures, 140℃-180℃, speed 25M-30M/min, and large smoke.
Six, weight and width
1. Be sure to measure the weight and door width before ordering. If the difference is too far from the requirements, you must report it and follow the order in time.
2. When setting the shape, pay attention to the difference between the center and the sides of the weight, and the difference between the weight and the weight should not be too far.
3. When finalizing, pay attention to whether the front, middle and back of the cloth are the same.
