Abstract

The invention discloses an environment-friendly sizing agent assistant, and a preparation method and an application of the assistant. The assistant is mainly applied to sizing of cellulose fibers or blend fibers and is characterized in that the sizing agent comprises 95-98% by mass of main material and 2-5% by mass of assistant, wherein the assistant is prepared from the following raw materials bymass percentage: 1-1.2% of starch viscosity reducer, 8-10% of plasticizer, 10-13% of wetting penetrant, 2-3% of soft smoothing agent, 1.5-2% of defoaming agent and the balance of deionized water. Theassistant is used for pure starch sizing and is applicable to the various cellulose fibers and the cotton-polyester blend fibers; no synthetic sizing agent is added; and PVA (polyvinyl alcohol)-freesizing is achieved in deed.

Description

Technical field: [0001] The invention relates to an environment-friendly size additive, a preparation method and application thereof, and is mainly used for sizing cellulose fibers or blended fibers. Background technique: [0002] As we all know, during the weaving process, warp yarns are subject to greater tension and friction, and are prone to breakage. In order to reduce warp breakage, improve weaving efficiency and gray fabric quality, it is necessary to sizing the warp yarns before weaving, so that the fibers in the yarns stick together and form a firm sizing film on the surface of the yarns, making the yarns become Tight and smooth, thus improving yarn breaking strength and abrasion resistance. The traditional sizing process, whether it is pure cotton products or polyester cotton products, usually uses a mixed size such as PVA and starch blended size. This type of size has excellent adhesion to synthetic fibers and cellulose fibers due to the addition of PVA. perform...
