Description

technical field

[0001] A quaternary compound denatured starch size and its preparation method and application, the invention belongs to the size used for textile processing. Background technique

[0002] Sizing is the key process before weaving. When sizing, the size forms a protective size film on the surface of the yarn or increases the cohesion between monofilaments to improve the wear resistance of the fabric, thereby improving the weavability of the warp yarn. The slurry should have certain adhesion, proper viscosity and viscosity stability, easy desizing and so on. Usually, one kind of slurry used alone cannot meet the process requirements, and generally several kinds of slurry should be selected and used together in proportion.

[0003] Currently used size mainly contains polyvinyl alcohol (PVA) type, acrylic chemical size and natural starch and modified starch three major categories. The first two types have good sizing performance, especially for synthetic fibers...
