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 rollers, and polish them with sandpaper. Or doily. (Such as stockings cloth, mesh cloth)
2. Styling of polyester cloth
1. Styling 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. After finishing There will be dye left on the case, so it cannot be made into light color immediately, it can only be made into black. You can also use scrap cloth to machine it several times to make it into light color.
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 edges 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 dye, the color of the gray fabric will change greatly when the cold and hot conditions change. The color matching must be done after the gray fabric has completely cooled down. The active material has not changed 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, the cloth should be pressed dry, and the hot air blower should be turned on to the maximum. Slowing the speed can reduce the shrinkage rate. If the customer’s 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. 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.
Fifth, fixed PU glue
1. Imported pulp, no discoloration at high temperature, 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 making a decision. If the width is too far from the requirements, it must be reported in time to follow the order.
2. When setting the shape, pay attention to the difference between the middle 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 door width are the same. </p
