摘　　要：文章旨在研究磷氮系阻燃剂对聚乳酸(PLA)钩圈同面粘扣带的阻燃性能的影响,通过正交试验,优化浸渍阻燃整理工艺,并研究不同阻燃剂质量浓度、浸渍温度和浸渍时间对其阻燃性能的影响,以期达到改善粘扣带阻燃性能的目的。探究不同的焙烘时间、温度、上胶阻燃整理与阻燃性能的关系。结果表明:阻燃剂质量浓度是影响浸渍阻燃整理效果的主要因素,粘扣带在60℃下,浸泡在阻燃剂质量浓度为250 g/L的阻燃液中2 h, 130℃焙烘180 s,损毁长度为8.6 cm;再涂覆阻燃剂质量分数为18%的阻燃胶,PLA钩圈同面粘扣带的损毁长度仅为5.2 cm,满足使用需求。Touch and close fasteners,also known as velcro,snap fastener,etc.,are a kind of textile with good fixing effect,with the advantages of easy use,easy adjustment,etc.They are one of the best alternatives to the traditional fixing method(buttons,zippers,etc.),and are widely used in clothing,shoes,bags,automotive interior and other fields.At present,the touch and close fasteners on the market are mainly divided into woven touch and close fasteners,knitted touch and close fasteners and injection touch and close fasteners,with the main raw materials being polyester and nylon and other chemical fibers.Flame retardant,antibacterial,acid proof,waterproof,yellow resistance and other functions can enrich the use of touch and close fasteners,to meet their various complex use environment.However,as a kind of textile,they are difficult to recycle,and a large number of waste touch and close fasteners are generated every year,which will seriously affect the ecological environment and economic benefits.Using poly lactic acid(PLA)fibers as the raw material to make fasteners can solve the problems that traditional fasteners are difficult to recover,difficult to handle and pollute the environment.PLA is derived from renewable resources(such as rice,corn and wheat),and is biodegradable to produce water and carbon dioxide.PLA products can be recycled as raw materials for weaving lactic acid polymers,and can also be used as fuel to be burnt for power generation.Compared with polyester,nylon and other chemical fibers,the release of CO 2 is significantly less.However,due to its inherent chemical composition and molecular structure,PLA is still a flammable material.The flammability and dripping of PLA limit the application of PLA touch and close fasteners in clothing and functional textiles(such as upholstery and curtains,and automotive industry).To improve the flame-retardant performance of PLA touch and close fasteners on one side,based on the characteristics of PLA fibers and the production process of touch and close fasteners,the flam
