Scouring


 Scouring is the first process carried out with room temperature or at suitable higher temperatures with the addition of suitable wetting agents, alkali and so on. Scouring removes all the  pectins , waxes, and makes the textile material hydrophilic condition  or water absorbent. See also scouring wool .                                                                                                                                                        Textile fibers which have been desized and are about to be bleached are scoured with a boiling alkaline caustic solution containing a surfactant and a solubilizing agent such as amin. This process provides fibers with a substantially reduced impurity level and an end product which is substantially more cond Textile fibers which have been desized and are about to be bleached are scoured with a boiling alkaline caustic solution containing a surfactant and a solubilizing agent such as amino tri(methylene phosphonic acid). This process provides fibers with a substantially reduced impurity level and an end product which is substantially more conducive to a subsequent dyeing process.ucive to a subsequent dyeing process.
