Lubricating: Explained in brief

Lubricating:
Wet processing and dye-bath lubricants are used in any operation in which rope marks, creases, crows feet buffing, abrasion can occur on textiles. In low liquor ratios, full-loaded winches and jets when heavy materials re processed, fiber lubricant is essential. The basic requirement is that is it should from a thin uniform protective coating around the fiber to lower the surface friction and flexural rigidity, thus minimizing the formation of durable creases during high temperature processing. The most suitable lubricant should have the properties so that it helps to emulsify, it does not undergo phase separation with extreme changes in pH and temperature, e.g. it is stable in high temperature and over a wide range of pH; and it should have excellent compatibility with all the chemicals in treatment bath, Suitable products are relatively hydrophobic surfactants, many of which also contain a proportion of solubilized or emulsified oil or wax.
