Problems solved by technology

But ① since the monomer composition of this water-soluble polymer is mainly acrylic acid, or methacrylic acid or acrylamide, the glass transition temperature of its copolymer is relatively high, which is not conducive to improving the hardness and brittleness of starch size; The slurry has permeability requirements, so the viscosity of the prepared slurry should not be too high, that is, the molecular weight of the synthesized water-soluble polymer should not be too high, so the mechanical strength is low; sufficient adhesion
Therefore, this nano size cannot be used as the main size of polyester staple fiber and its blended yarn

Abstract

The invention discloses two-component acrylic polymer / montmorillonite nano-composite textile sizing agent, which is non-transparent, and consists of homogeneous hydrophilic acrylic polymer solution and relatively hydrophobic acrylic polymer latex dispersed therein with a chemical combination generated by grafting copolymerization between the solution and the latex. The preparation method for the sizing agent uses a two-stage method of latex polymerization and solution polymerization to make monomers in the solution polymerization permeate into the latex particles and generate grafting polymerization or copolymerization with the latex polymers in the latex polymerization. The relatively hydrophobic acrylic polymer latex in the sizing agent has higher latex molecular weight and lower glass transition temperature to provide viscosity for hydrophobic polyester fibers and improve hard brittleness of starch sizing agent, and the hydrophilic acrylic polymer solution can ensure water solubility of the sizing agent, is favorable for desizing and keeping moisture regain of sizing film and affinity to cotton fibers, so the method is suitable for mixing with starch for sizing the polyester short fibers and mixed fabric warps thereof.

Description

technical field [0001] The invention belongs to the technical field of acrylic polymer / montmorillonite nanocomposite textile slurry and its preparation, in particular to a two-component acrylic polymer / montmorillonite nanocomposite textile slurry and a preparation method thereof. The material is especially suitable for sizing treatment of polyester staple fiber and its blended warp yarn. Background technique [0002] The surface effect, quantum size effect, and macroscopic quantum tunneling effect of inorganic nanoparticles have greatly changed the physical and chemical properties of polymer nanocomposites. Montmorillonite has a natural nano-scale layered structure and is one of the most suitable inorganic particles for the preparation of polymer nanocomposites found today. For example, the preparation method of the nylon / montmorillonite flame-retardant composite material disclosed in the Chinese invention patent with the application number of 200610022230 is to uniformly m...
