1. Nylon gray fabric
1. Setting temperature: 160℃-180℃. Speed: 20M-25M/min.
2. The color of the setting temperature changes greatly, 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)
Second, 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 the red dye is not good. The dye will be left on the chassis after finishing. It cannot be made into light colors immediately, and can only be made into black. You can use scrap cloth and machine it several times to 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 cloth, pay attention to the thickness of the center and sides of the cloth. The temperature should be well controlled and not too high. Slow down the machine speed and pull it 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.
Three, 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. The color matching must be done after the gray fabric is completely cooled. The reactive material will not change much.
3. Rayon is prone to aging due to 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 the maximum and the machine speed should be slowed down to reduce the shrinkage rate. Shrinkage rate, if customer requirements are high, shrinkage testing is required.
5. If the customer requires that the fabric surface be untwisted, it must be shaped in a twill pattern.
Four. Silk shaping
1. Styling temperature 100℃-120℃, speed: 20M-30M/min
2 , Silk shaping hot air is turned down, and the door width is 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, fix the 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.
6. Gram weight and door width
1. Be sure to measure the gram weight and door width before setting. If it is too far from the requirements, report it in time Follow orders.
2. When setting the shape, you should pay attention to the difference between the middle and the sides of the weight, and the difference between the two sides should not be too far.
3. When finalizing, pay attention to whether the front, middle and back of the door width of the cloth are the same. </p
