Embodiment Construction

[0015] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0016] Such as figure 1 As shown, a spinneret of the present invention includes a plate body 1, and a plurality of spinneret hole groups are arranged on the plate body 1, and each spinneret hole group includes a "C" shaped slot hole and at least one A circular hole, the circular hole is located near the "C" shaped slot.

[0017] Preferably, the number of the circular hole is one, and the circular hole is located in the middle area of ​​the two ends of the "C"-shaped slot.

[0018] A method for producing multi-dimensional hollow elastic polyester yarns by using the above-mentioned spinneret, which has the following steps: ① melting the polyester, and spraying p...

Abstract

The invention relates to a spinneret plate and a method for producing multi-dimensional hollow elastic polyester yarn. The spinneret plate comprises a plate body, wherein a plurality of spinneret orifice sets are arranged on the plate body, each spinneret orifice set comprises a C-shaped slot and at least one round hole, and the round holes are located near to the C-shaped slots. According to the method for producing the multi-dimensional hollow elastic polyester yarn, based on the improvement on the prior art, the multi-dimensional hollow elastic polyester yarn can be produced, the elongation at break can reach over 60%, the boiling water shrinkage is lower than 5%, the elasticity is ultra-high, and the multi-dimensional hollow elastic polyester yarn can replace fur of animals and is the alternative material of high-grade shell fabric.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a spinneret and a method for producing multidimensional hollow elastic polyester yarns. Background technique [0002] The characteristic of polyester yarn is that it can resist chemical substances and frequent washing, and reduce the phenomenon of fading and decolorization of clothes. Therefore, hotel uniforms, stone milled blue denim clothes, sportswear or children's clothing will be made of polyester yarn. Hollow cotton is made of high-quality polyester and three-dimensional crimped hollow fiber with excellent performance, U-shaped hollow fiber and ES fiber as raw materials. [0003] The properties of polyester yarns with excellent performance are: higher elongation at break, lower shrinkage in boiling water, stronger elasticity, etc. In the prior art, polyester yarns are basically processed by spinnerets. [0004] The spinneret is also called the spinning ca...
