In the commonly used soft finishing, the most common and simple way is to treat the fabric with a সফটনার, so that the সফটনার forms a protective film on the surface of the fabric, reducing the friction between the components in the fabric and the friction between the human body and the fabric, thereby Play a soft and smooth function. According to statistics, the main methods used for fabric softening are mechanical softening, chemical softening and biological enzyme processing. The mechanical softening effect is not long-lasting and the effect is not obvious; the chemical finishing effect is better, and it has changed the defects of the stiffness and poor softness of the fabric. Biological enzyme processing is an environmentally friendly and effective processing method that has emerged in recent years.In the dyeing and finishing process, due to the characteristic factors of the fibers that constitute the fabric, or in order to give the fabric a certain function, it is often necessary to use a সফটনার
to improve the smoothness and softness of the fabric, and improve the comfort of the fabric. In the soft finishing of cotton fabrics with water-silicone oil সফটনার and bath সফটনার, orthogonal experiment and single factor experiment were used to explore the best finishing process of cotton fabric soft finishing, and the hand feeling and whiteness of cotton fabric before and after soft finishing were tested.
The role of সফটনার
1. As a finishing agent for fabrics, সফটনার can obtain a soft, fluffy and plump hand feeling, and at the same time, general mechanical properties, drape and lubricity can be improved.
2. The সফটনার used as a lubricant can reduce the friction between the yarns, thereby improving the wear resistance. At the same time, it can reduce needle cutting and needle temperature during sewing, and reduce needle abrasion.
3. The combination of সফটনারs and other finishing auxiliaries, especially the combination of resins, can effectively improve wear resistance and tear resistance, and improve wrinkle recovery performance.
