In the rolling groove of the setting machine, the soft finishing can meet the requirements of the customer on the cloth, and it is not easy to be scratched on the guide wheel. The tenter setting makes the fabric cloth surface flat and stable, which can eliminate the formation during the dyeing and finishing process. Wrinkles, creases, and at the same time, the molding process conditions must be strictly controlled during the setting
(1) The setting temperature should be determined according to the elastic shrinkage rate and thickness of the fabric. If the temperature is too high, the strength will decrease, the elasticity will decrease, and the fabric may be discolored. The setting temperature is too low, the fabric is easy to be curled, the width is unstable, and the shrinkage rate is large;
(2) The speed of the fixed speed depends mainly on the length and setting temperature of the shaping zone. The speed of the vehicle is too fast and the shaping is ineffective. The fine wrinkles are not easy to solve during the dyeing and finishing process. The vehicle speed is slow, especially under high temperature conditions, the fabric is yellowed and the elasticity is decreased.
(3) After setting the super-feeding of the fabric, after determining the width of the fabric, select the appropriate super-feeding amount and tension, which affects the gram weight and elasticity of the fabric, and the generation of wrinkles on the fabric surface, such as small fabric tension and super-feeding. The cloth surface is not flat, it is difficult to eliminate the fine wrinkles produced by the fabric during the dyeing process, the tension is large, and the super-feeding amount is small, which causes curling during heat setting.
