Problems solved by technology

[0003] Currently on the market, the traditional fine-denier fiber products with a fineness of 0.3-0.5D / F are usually produced by segmented orange-shaped composite fiber spinning components. Although the fabrics produced by spinning such components are soft to the touch, It is easy to fluff, and dyeing is prone to chromatic aberration

Abstract

The invention discloses a superfine polyester conjugate spinning component with creative design and simple structure, which comprises a slant hole plate, a radiation plate, a composite plate, a positioning pin and a spinneret plate; the difficulties are as follows: a boss of a discharge surface is provided with a star-shaped structure; the star-shaped structure is provided with a star-shaped diversion trench; the cross section of the bottom of the trench is designed into a rectangle with the chamfer angle of R0.03 to R0.05; the creative and simple design of the star-shaped structure and the chamfer angle at the bottom of the star-shaped diversion trench prevents flowing dead corners produced by fluid turbulent eddies, so that the fluidity of different types of polymer is greatly improved; therefore, the fabric made of the product spun by the spinning component is soft to touch, does not fuzz, has no color difference in dyeing, and very conveniently solves the technical difficulties of the industry which cannot be overcome.

Description

Technical field: [0001] The invention relates to a component of chemical fiber spinning machinery, in particular to the structural improvement of an ultrafine polyester-nylon composite spinning component. Background technique: [0002] The traditional polyester / nylon composite spinning components include oblique orifice plate, radial plate, composite plate, positioning pin and spinneret. Its function is to make the polymer melt finely filtered, fully mixed, evenly distributed, and extruded into filaments through the micropores of the spinneret under a certain pressure during the melt spinning process. The polyester nylon composite spinning component is called As the heart of the technological process, the production of different varieties on the same set of equipment is realized through different spinning components. The quality of spinning components directly affects the normal production of spinning products. [0003] Currently on the market, the traditional fine-denier ...
