Abstract

The invention discloses a formula of a slurry capable of being applied to weaving under a low sizing rate. The slurry comprises polyvinyl alcohol (PVA), modified starch, and dimethyl sulfoxide. The invention also discloses a sizing method capable of being applied to weaving under a low sizing rate. The method comprises the following steps: weighing slurry, blending slurry, pumping slurry into the slurry tank of a sizing machine, and carrying out sizing on warp yarns through a double-soaking double-pressing mode. The slurry formula is simple. The slurry only comprises PVA and etherified potato starch, the error of slurry blending can be reduced, moreover, the storage management becomes convenient, and the formula is accord with development trend of less components of slurry. DMSO is taken as the compatibilizer to solve the problem that the performance of slurry is influenced by the different thermodynamic compatibilities of different slurries. The yarns produced by the provided sizing technology can meet the requirements of weaving under the condition of low sizing rate, the using amount of slurry is largely reduced, the production cost for the textile enterprises is reduced, the pollution generated by pretreatment of printing and dyeing is reduced, and thus the formula and method have a good market prospect.

Description

technical field [0001] The invention belongs to the technical field of textile sizing, and in particular relates to a size formula suitable for weaving under low sizing ratio conditions; the invention also relates to a sizing method suitable for weaving under low sizing ratio conditions. Background technique [0002] The original yarn has the defects of long hairiness, non-wear resistance, and insufficient strength, so the warp yarn must go through the sizing process before weaving to improve the resistance of the warp yarn to withstand repeated tensile loads and periodic, repeated friction. During the weaving process on the loom: [0003] First, warp yarns are subjected to periodic and repeated tensile loads. Taking the weaving of a cotton fabric as an example, its weft density is P w =335 threads / 10cm, the shrinkage rate of the warp yarn is 10%, and the speed of the machine is 600rpm. In each revolution of the loom, the length ΔL of the warp yarn sent by the weaving beam ...
