Syntheses and Properties of New Acrylic Size Latex

An acrylic size 8K is synthesized by emulsion polymeriza-tion,the properties of which depend on the monomersparticipating in copolymerization and reaction tech-niques.The structure of the size molecule is character-ized by infrared spectrum.The hardness of the size filmis characterized by the glass transition temperature of thesynthesized copolymer which is a flexion point of DSCcurve.The micro state of the size adhering to yarns isshown by scanning electron microscopy.According tomeasurements,the acrylic size Size 8K has good adhesivepower and low water absorption,proper viscosity andhigh thermal stability,strong abrasion resistance andgood compatibility with other sizing agents.It aslo im-proves yarn breaking strength, yet has limited elongationloss.The acrylic size is a potential size to replace PVAand to apply to high speed looms.

Syntheses and Properties of New Acrylic Size Latex

An acrylic size 8K is synthesized by emulsion polymerization, the properties of which depend on the monomers participating in copolymerization and reaction techniques. The structure of the size molecule Is characterized by infrared spectrum. The hardness of the size film is characterized by the glass transition temperature of the synthesized copolymer which is a flexion point of DSC curve. The micro state of the size adhering to yarns is shown by scanning electron microscopy. According to measurements, the acrylic size Size 8K has good adhesive power and low water absorption, proper viscosity and high thermal stability, strong abrasion resistance and good compatibility with other sizing agents. It also improves yarn breaking strength, yet has limited elongation loss. The acrylic size is a potential size to replace PVA and to apply to high speed looms.
