Background
Denim is mostly a high-thick-count high-density fabric, and warp yarns of the denim need to be sized. The denim sizing aims at enhancing the friction resistance of the yarn, reducing the elongation and attaching the hairiness. Sizing yarns not only need to bear repeated friction between machines and yarns and between yarns to stop spinning, but also need to receive the test of secondary hairiness generated by the yarns in the friction process.
The sizing mechanism is as follows: after the warp yarns are sized, the sizing agent forms a layer of sizing film around the yarn body, and the sizing agent permeates into single fibers to stick the single fibers, so that the bundling property and the strength of the composite yarns are improved, and the wear-resisting strength of the yarns is enhanced. Therefore, the sizing agent has better permeability and covering property, and the good permeability of the sizing agent can improve the wear resistance of the yarn, thereby meeting the requirements of high-tension weaving, opening, beating-up and repeated stretching of the jean. The sizing agent has good covering property, can form a sizing film on the surface of the yarn to be attached to filoplume, can bear the friction of a reed and a heddle, and keeps the cloth surface smooth.
