The invention discloses a processing method of using leftover materials for manufacturing polyester short fibers. The method comprises the following steps of recycling and opening, selection of materials, disinfection, pre-spinning, mixing of the materials, carding, net laying, needling, post-spinning, cutting and obtaining of finished products. The provided processing method of using the leftovermaterials for manufacturing the polyester short fibers aims at solving the technical problems that the production and processing cost of the polyester short fibers in the prior art is high, waste ofresources and environmental pollution are easily caused, and the safety is low. The processing method of using the leftover materials for manufacturing the polyester short fibers has the advantages ofbeing low in cost, capable of saving resources and protecting the environment, sanitary, high in safety and the like.
Description
technical field [0001] The invention relates to the technical field of polyester staple fibers, in particular to a processing method for producing polyester staple fibers from leftover materials. Background technique [0002] Polyester staple fiber is a fiber obtained by spinning polyester (that is, polyethylene terephthalate, PET for short, which is polymerized by PTA and MEG) and then cutting it into tow. Polyester staple fiber products are mainly used in the cotton spinning industry, spinning alone or blended with cotton, viscose fiber, linen, wool, vinylon, etc. The obtained yarn is mainly used for clothing weaving, and can also be used for home decoration fabrics, packaging cloth, Filling and insulation materials. The strength of polyester staple fiber is nearly 1 times higher than that of cotton and 3 times higher than that of wool, so it is strong and durable. Polyester staple fiber can be used at 70-1700C, and it is the best heat resistance and thermal stability amo...
