무용제형 저기포성 정련제의 제조에 관한 연구
A Study on the Preparation of Solvent-Free Low Foaming Scouring Agents
초록
Polyoxyethylene(30) octadecylbenzylammonium chloride(POAC), propylene oxide와 ethylene oxide의 블럭 공중합체[p(PO-b-EO)glycol], Sedlan FF-200(FF-200) 및 Polyoxyethylene(10) nonylphenyl ether의 술폰산-아민축합물 (PSAC) 등을 블렌딩하여 무용제형 저기포성 정련제 (LFSA)를 제조하였다. LFSA로서 여러 가지 물성시험을 해 본 결과 FF-200/POAC/p(Po-b-EO) glycol/PSAC/water(20g/10g/5g/5g/60g) 혼합물(LFSA-5)은 세정력, 침투력, 유화력, 알칼리 안정성 등이 양호하였으며, 수질오염에 대한 영향이 크지 않았다. LFSA-5의 정련효과는 정련전 후의 염색온도에 따른 염착률의 변화로서 확인하였는데, 정련전 PET 직물인 경우는 70℃에서 4.5%의 염착률을 나타낸데 반하여, LFSA-5로서 정련된 직물은 1.3%의 염착률을 나타냄으로써 LFSA-5의 정련효과가 양호함을 알 수 있었다. 또한 LFSA-5는 Ross and Miles법에 의한 거품 생성 직후의 기포력이 포고 6mm로 나타났고, Ross and Clark법에 의한 기포력이 30℃에서는 포고 300mm 이하로, 80℃에서는 20mm를 각각 나타내어 양호한 저기포성 정련제임이 입증되었다.
Solvent-free low foaming scouring agents(LFSA) were prepared by blending of polyoxyethylene(30) octadecylbenzylammonium chloride(POAC), block copolymer of propylene oxide-ethylene oxide[p(PO-b-EO) glycol], Sedlan FF-200(FF-200) and sulfonic acid-amine condensate of polyoxyethylene(10) nonylphenyl ether(PSAC). In consequence of several tests, FF-200/POAC/p(PO-b-EO) glycol/PSAC/water (20g/10g/5g/5g/60g) mixture (LFSA-5) showed good cleaning power, penetrating ability, emulsifiability and stability to alkali, and gave less problem in water pollution. Scouring effect of LFSA-5 was investigated by the change of percentage of exhaustion before and after scouring at various dyeing temperatures. The percentage of exhaustion of the unscoured PET fabric was 4.5% at 70℃, while that scoured with LFSA-5 was 1.3% at the same temperature, which proved LFSA-5 to be a good scouring agent. Moreover, the foaming power of LFSA-5 measured by Ross and Miles method was 6mm foam height immediately after
