Description
Technical Field
[0001] The utility model relates to the technical field of polyester yarn processing, in particular to a texturizing machine for processing regenerated polyester yarn. Background Art
[0002] Polyester yarn is a fiber made of polyethylene terephthalate, a fiber-forming polymer made by esterification or ester exchange and polycondensation reaction of purified terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials. It is made of fiber by spinning and post-treatment. The texturing machine is a textile machine that can process untwisted yarns such as polyester and polypropylene into stretch yarns with medium elasticity and low elasticity through false twisting.
[0003] The raw yarn rack is an important component of the texturizing machine, which is used to hang the raw yarn tube wrapped with raw yarn. The existing raw yarn rack mainly includes a frame body and a plurality of wire hanging rods fixed on the frame body. In order to facilitate the hanging of the raw yarn tube, the diameter of the wire hanging rod is smaller than the diameter of the raw yarn tube. As a result, when the raw yarn is about to be unwound, the wire hanging rod has a smaller diameter than the raw yarn tube. Under the pulling action of the raw yarn, the raw yarn tube that is about to be used up is lighter and easy to fall from the wire hanging rod, resulting in poor use effect. In addition, when the polyester yarn is false-twisted, the texturizing machine rotates at a high speed. Improper operation can easily lead to excessive force during texturizing, resulting in polyester yarn breakage, causing processing errors. For this reason, we provide a texturizing machine for processing recycled polyester yarn to solve this problem. Utility Model Content
