Abstract

The invention discloses a production method of super-imitation cotton fabric using waste polyester bottles. The method includes classifying the waste polyester bottles, and subjecting recycled polyester with intrinsic viscosity of less than 0.63g / dl to alcoholysis and esterification to obtain copolyester with a good hydrolytic function; subjecting recycled polyester with intrinsic viscosity of greater than 0.63g / dl and the copolyester to blending, fusion and spinning to obtain blend fibers; spinning the blend fibers to obtain fabric, performing treatment with dilute alkali solution to remove material C before drying, and subjecting the dried fabric in impregnating solution composed of polyethylene glycol monoester maleate and potassium persulfate to immersion treatment to obtain novel polyester fabric with super-imitation-cotton performance. According to the method, the waste plastic bottles are utilized to prepare the novel super-imitation cotton fabric, thus visual pollution can be avoided, resources can be recycled, pollution can be reduced, burden on municipal solid waste disposal can be relieved, land consumption can be saved , and good economic benefits can be achieved.

Description

technical field [0001] The invention belongs to the technical field of preparation of environment-friendly materials, and in particular relates to a method for preparing super-cotton imitation fabrics by using waste polyester bottles. Background technique [0002] In recent years, China's national economy has maintained a steady and rapid development, and environmental protection and resource regeneration have become an important part of my country's new economy and harmonious society construction. my country is one of the top ten plastic products producing and consuming countries in the world. A large number of plastic products are produced and consumed every year. If it is not handled properly, it will bring negative effects to the environment and cause serious environmental pollution. These waste plastic packaging will not only cause "visual pollution", but even produce an ecological crisis. [0003] Super-imitation cotton looks like cotton (visual), feels like cotton ...
