1.polyurethane resin for Anti-pilling and pilling mechanism
Pure cotton knitted fabric after boiling, dyeing, finishing and other processing, its surface will produce a lot of wool, together with electrostatic effect, wearing a period of time after the fabric surface will rise and pilling, affect the beauty and comfort.Polyester-cotton blended knitted fabric is in use and washing process, due to continuous friction, pilling phenomenon is serious, so that the feel and appearance of the fabric become poor, affect its performance.Resin finishing is an effective method to improve the fabric anti-pilling.The principle is that the polyurethane resin can be used on the fiber surface to form a film in the form of cross-networking, so that the fiber surface is coated with a layer of wear-resistant resin film, to weaken the slip between the fibers;At the same time, the resin is evenly cross-linked and condensed on the surface of the yarn, so that the fiber end sticks to the yarn, and it is not easy to pilling during friction.Resin finishing can improve the anti-pilling and anti-wrinkle and anti-static properties of the fabric.
