Abstract

The invention discloses a water-soluble polymer for treating cotton-type warp yarn and its application. The water-soluble polymer for treating cotton-type warp yarns is a carbon-chain polymer acrylic derivative, and the side groups are composed of R groups, M groups, and R' groups. According to the effects of the three types of side groups, the mass percentage of its structure is R 40% to 70% of the base, 45 to 25% of the M base, and 15 to 5% of the R' base. The wet warp yarn sized by the water-soluble polymer of the present invention does not need to be specially dried. During the sizing process, it is dried by cold wind and wound on the weaving shaft without heating the drying cylinder of the sizing machine or directly passing through the air. , it can be used in subsequent weaving, the method is energy-saving, and the slurry is environmentally friendly and harmless.

Description

technical field [0001] The invention relates to the synthesis and application method of a polymer used in the field of textile cotton warp yarn sizing, in particular to a hot water soluble polymer, which belongs to the new technology of textile printing and dyeing, environmental protection and energy saving. Background technique [0002] Textile cotton-type warp yarn is processed by cotton-type staple fiber through spinning process, and cotton-type staple fiber in warp yarn entangles and rubs against each other to form warp yarn strength. When subjected to force, the fibers in the warp yarn break and slide each other, and the warp yarn will break, which is the internal reason why the cotton-type warp yarn needs to be sized and bonded when weaving. During weaving, the warp yarns are subjected to severe and repeated friction by warp stoppers, healds, reeds, adjacent yarns, etc., and they are subjected to more than 4,000 times of friction from the back beam of the weaving shaft...
