| Softener is a kind of chemical substance which can change the static and dynamic friction coefficient of fiber, and softening finishing is an important finishing process in printing and dyeing process. 1、 Function of softener 1. The natural oil lost in scouring and bleaching of natural fiber is supplemented to make the hand feel more ideal. 2. Attached to natural fiber or synthetic fiber, improve smoothness and strength, improve handle. 3. The wearability of fabric can be improved by some properties of softener. In order to achieve some of the above functions, softener is generally a kind of material with the smoothness and feel of grease. Adhesion to the surface of fiber can reduce the friction resistance between fibers and make the fiber produce lubrication and softness. Some softeners can crosslink with some reactive groups on the fiber to achieve washability. 2、 Requirements for softeners 1. Under various soft processing conditions, the working fluid should be stable. 2. It does not reduce the whiteness and color fastness of fiber or fabric. 3. The soft treated fiber or fabric is not easy to change color due to heat, and the color, handle and smell should not change during storage. 4, if the softener is emulsion, its emulsion stability is better. 5. According to the different requirements, the fabric should be treated properly. It has water or dry cleaning resistance. 6. There is no adverse effect after skin contact. There are many kinds of textiles, but the fibers are different, and the fabric specifications, uses and finishing requirements are different, so the selection of softeners is also different. According to the softening mechanism and function of all kinds of softeners, the softeners that meet the requirements should be selected. In addition, the performance of each softener is always limited. In order to obtain the effect of good performance, two or more softeners can be used in combination (or compounded into a new softener product), so as to bring better effect of soft, plump and smooth feel. |
