Studies on the Durable Softening Water Repellents(II) -Water Repelling Treatment of Nylon Fabrics with Water Repellents Based on Acrylic Copolymer-

내구유연발수제에 관한 연구(II) -아크릴 공중합체를 주제로 하는 발수제의 나일론 직물에의 발수처리-

For the purpose of manufacturing water repellents of acrylic copolymer, quaternized stearylmetacrylate-2-diethylaminoethylmethacrylate (SDMAC) as a mother resin and quaternized 1-behenoylaminoethy1-2-docosyl imidazoline (BADIC) to increase the softening effect and the water repellency were treated by blending waxes and their emulsifier in various proportions to give water repellent PPSBC. After treatment of PPSBC with or without resin to nylon fabrics water repellency, durability to repeated washing, tear strength and crease recovery were found to show better results. Durable softening water repellents PPSBC increased the stability to acid, alkali and other chemicals and decreased the influence to the color fastness to crocking of dyed textiles. The water repellency mechanism of nylon fabrics treated with PPSBC was discussed in detail and the structure of the nylon fabrics was observed with a optical microscope.
