One-step foam finishing of flame retardancy and three-proof finishing for bio-based polytrimethylene terephthalate fabrics

In order to improve the functionality of bio-based polytrimethylene terephthalate(PTT)fabrics and meet the needs of energy saving and emission reduction for ecological dyeing and finishing,foam finishing technology are used to treat bio-based PTT fabrics for flame-retardancy and three-proof one-step finishing.Using the responsive surface experimental design and optimization method,the effects of the concentration of the flame retardant and the three-proof finishing agent,liquid carrying rate and the baking temperature on the finishing effect were analyzed.The optimal finishing process was as follows:the concentration of flame retardant and three-proof finishing agent are 390 and 43 g/L respectively,the liquid carrying rate is 42%,and baking is performed at 141℃for 1 min.The research results show that the PTT fabrics finished under the optimal technological conditions have excellent flame retardant properties and good three-proof effects.The flame retardant grade reaches the national B1 standard,and the contact angles of the water phase and the oil phase reach 145.6°and 129.2°,respectively.In addition,after 20 washings and 50 rubs,the fabric still maintains good flame retardant and three-proof effects.The experimentally researched foam multifunctional finishing method provides an effective way to improve the green and clean production of bio-based fiber materials.
