Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with specific embodiments.

[0016] The production process of flat polyester wool tops, the process steps are as follows: raw material drying→screw extrusion and spinning→winding and clustering→post-treatment of tow→cutting of tow and making sliver→one needle comb→two needle combs→ball needle comb ,

[0017] (1) In the raw material drying process: polyester chips are used as raw materials and dried in a vacuum drum device;

[0018] (2) In the screw extrusion and spinning process: in the screw extruder, the dried polyester chip raw materials are melted and extruded and sprayed, and the polyester chip raw materials are driven by a screw with a rotating speed of 60m / s. Preheat through zone 1 and zone 2 of the screw extruder in sequence, the temperature of zone 1 is 270°C, the temperature of zone 2 is 275°C; then melt through zone 3 and zone 4 in sequence, the temperature of zone 3 is 280°C , t...

Abstract

The invention discloses a production technology of a flat filament polyester top. The production technology comprises technological steps as follows: drying of raw materials, screw extrusion jet spinning, winding for bundling; tow aftertreatment, tow cutting-off for strip preparation, primary gilling, secondary gilling and balling gilling. The flat filament polyester top prepared with the method has flat filaments, long fiber, high brightness and high stereoscopic effect, touches elastic, soft and smooth, and is more suitable for dyeing than common chemical fiber, thereby being applicable to production of imitated fur garments.

Description

technical field [0001] The invention relates to the field of wool top production technology, in particular to a production technology of flat polyester wool top. Background technique [0002] With the improvement of people's living standards, people have more and more demand for fur clothing, but the amount of fur is limited, so it is necessary to produce imitation fur clothing to meet people's needs, but the existing tops cannot be used for imitation fur Production of clothing. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a production process for producing fur-like garments and high-brightness flat polyester wool tops. [0004] In order to solve the above problems, the technical solution adopted in the present invention is: the production process of flat polyester wool tops, the process steps are as follows: raw material drying→screw extrusion and spinning→winding and clustering→post-treatment of tow→cutting of tow ...
