Study on the Technology of Oil and Shrink-Repellent Finish
Jin Hui Peng · Journal of Nantong University · 2011
Twenty experiments have been conducted by using central rotational design with five levels and three variables including wrinkle resistant finishing agent RESIN BRT,oil-repellent agent PM-492 and magnesium chloride.After wrinkle recovery angle,releasing formaldehyde,tearing strength retention value were analyzed,the better technology of oil-repellent and shrink-repellent finish was revealed,namely RESIN BRT 80～85 g/L,oil-repellent agent PM-492 40 g/L,magnesium chloride 12～13 g/L,PH value of finishing bath 4.2,two-dip-two-dry,pre-curing at 105～110 ℃ for 3 minutes and curing at 165～170 ℃ for 2 minutes.After being processed,the water and oil-repellent performance of lining cloth could be marked as 120,the washing dimension size rate to-0.7%,the released formaldehyde of fusible lining cloth less than 40 mg/kg,the wrinkle recovery angle more than 270°.Therefore,it can be concluded that the quality of lining cloth being processed by this technology conforms to the demand of best quality.
