The invention provides a preparation method of a matte regenerated PET clothing
fastener based on waste
textile recovery, and relates to the technical field of high-end clothing accessory manufacturing, and the preparation method comprises the following steps: S1, high-valued
recovery of
polyester from waste textiles; s2, composite modification of recycled PET; s3, performing injection molding on a primary
fastener blank; s4, carrying out micro-
etching treatment on the surface of the
fastener primary blank; wherein the high-valued
polyester recovery of the waste textiles comprises the steps of NIR sorting, wet crushing, enzymolysis purification, supercritical COextraction,
solid-phase tackifying and
extrusion granulation. Through NIR sorting, wet crushing, enzymolysis purification, supercritical COextraction,
solid-phase tackifying and
extrusion granulation, nano-composite modification and surface micro-
etching technologies, matting and high performance of the regenerated PET fastener are realized, the product has high-end texture and
environmental protection properties, a'clothing-to-clothing 'closed-loop green cycle is realized, and the product has a good market prospect. And green upgrading and
sustainable development of the clothing industry are accelerated.
