The main physical indicators and control methods that need to be controlled for fabric heat setting

1. Door width
Door width can be produced in Adjust directly on the setting machine. The adjustable door width on the shaping machine is in centimeters, but the company’s order requirements generally require that the door width be in inches. Therefore, during the production process, inches must be converted into centimeters before adjustment can be made. Conversion formula: 1 inch = 2.54 centimeters.
2. Gram weight
Generally, the gram weight is determined by adjusting the excess Feed to control. Under the condition that the other tensions remain unchanged, within a certain range, the greater the overfeed, the heavier the gram weight, and the smaller the overfeed, the lighter the gram weight.
3. Cycle
Cycle is closely related to gram weight and refers to Repeating dimensions of the pattern from start to end. Its control method is the same as that of gram weight. Typically, cycling is controlled by adjusting overfeed. When the remaining tension remains unchanged, within a certain range, the larger the overfeed is, the shorter the cycle will be, and the smaller the overfeed will be, the longer the cycle will be.
4. Shrinkage
Shrinkage is the most important physical indicator that needs to be controlled when shaping. one. The shrinkage must be even and reasonable. For styling, shrinkage is mainly controlled through resin or pre-shaping. For pure cotton fabrics, resin is generally used to control shrinkage. When the resin can fully react, the greater the amount of resin, the better the shrinkage, but the problem that arises is that the strength decreases more. Therefore, the amount of resin is subject to certain restrictions.
