1. Formula: This refers to the finishing solution used during finishing. The proportions of various chemicals in the solution determine the fabric's hand feel, slippage, and color after finishing.
2. Roller Pressure: The roller pressure used during finishing determines the amount of finishing solution carried by the fabric, significantly impacting its hand feel and color.
3. Drying Temperature: The drying temperature during finishing is one of the main factors affecting finishing quality, especially in resin finishing processes. Finishing temperature significantly affects the fabric's dimensional stability and surface smoothness. For softening finishing, the drying temperature should be controlled so that the fabric is only slightly dry. Excessive temperature will affect the fabric's hand feel.
4. Overfeed: The degree of overfeed directly affects the style of woven fabrics. It generally refers to the unique properties of the fabric that distinguish it from other products, mainly including appearance and intrinsic properties. External attributes are usually quite obvious and readily accepted by processors and wearers, such as creases, small diamonds, and pearl-like particles on the surface of woven fabrics. The appearance of woven fabrics is a major aspect of their overall style. However, internal style sometimes requires inspectors or wearers to identify through simple methods, such as the fabric's feel and elasticity. The weft density affects the fabric's shrinkage performance, and appropriate tension during production is necessary to prevent wrinkling and weft skew.
5. The width of the fabric after setting determines its width, ensuring that the width of the set woven fabric meets process requirements and, after pre-shrinking, meets customer requirements.
6. Heat setting process conditions for woven fabrics: Heat setting typically involves maintaining the fabric at a certain size, heating it for a specific time under specific temperature and humidity conditions, and then cooling it. Therefore, the main process conditions for heat setting are temperature, time, tension, and the swelling agent.
