Abstract

The invention relates to a method for spinning imitated cotton and linen fibers by waste polyester, which belongs to the field of spinning. The method comprises the following steps: a first step of regenerating, modifying and pelletizing the waste polyester; a second step of pre-crystallizing raw materials; a third step of drying the raw materials; a fourth step of melting and extruding, filteringmelt, and introducing the melt into a metering pump; a fifth step of pumping the melt into a distributor; a sixth step of distributing the melt to a spinneret combined part in a balanced mode; a seventh step of introducing the melt into a different-section spinneret template; an eighth step of spraying out fine flow with multiple different-section melts; a ninth step of blowing air to cool the melt fine flow; a tenth step of enabling an oil-coating bunching agent to be anti-static; an eleventh step of pre-networking; a twelfth step of precisely winding; a thirteenth step of stretching and reshaping twice; a fourteenth step of defining a primary network; and a fifteenth step of winding a finished product.

Description

technical field [0001] The invention relates to a method for spinning cotton-like linen fibers from waste polyester, which belongs to the field of spinning. Background technique [0002] To produce recycled polyester filament from old polyester bottles, it is first necessary to wash and process the old polyester bottles into recycled polyester bottle flakes. It is required to be cleaned and processed as clean as possible. The higher the cleanliness, the better. The characteristics of the irregular fineness section of natural cotton and linen fiber appear in the cotton-linen filament fiber spun by the two-step method of waste polyester. It presents the unique functions of natural cotton and linen fibers. [0003] In view of this, the patent document with the application number 201611174221.6 discloses a method of making greenhouse insulation quilts by using waste and old clothes. Contents of the invention [0004] The purpose of the present invention is to overcome the ab...
