Problems solved by technology

[0005] However, in the spinning process, the high polymers of different components often have different viscosities, which may cause "bend angle" problems at the spinneret during the spinning process and cannot be spun smoothly, or poor compatibility leads to differences between components. to crack

Abstract

The invention provides a special-shaped spinneret plate, which comprises a spinneret plate body and a plurality of spinneret orifices with different section shapes. The spinneret orifices are distributed along a plurality of concentric circles of the spinneret plate body. The invention further discloses a manufacturing method of the special-shaped spinneret plate. In spinneret operation of the special-shaped spinneret plate manufactured according to the method, due to the spinneret orifices with different section shapes, fibers sprayed from the different spinneret orifices are different in curvature and spiral twisting direction. By the optimized spinneret orifices arrangement mode, hollow structures are formed inside the fibers, hollowness reaches 15%, and fluffy structures are formed among the fibers. Therefore, cost is saved, and a production process is optimized.

Description

technical field [0001] The invention relates to the technical field of fabric fiber manufacturing, in particular to a special-shaped spinneret and a manufacturing method thereof. Background technique [0002] With the widespread concern of elastic fibers, fibers with high elongation, strength, and aging resistance have gradually gained people's favor. [0003] The composite fiber uses two or more shrinkage properties - such as viscosity - different polymer materials to produce fibers with a hollow structure, which is a type of polymer with different structures or properties, made by composite spinning Curled spandex. [0004] Because the components in the fiber have different shrinkage and initial modulus, when the composite fiber is spun and drawn, different shrinkage effects will occur due to the different shrinkage stresses of the components after heating, and the components are pasted together, so the shrinkage There is a coordination and restraint effect on each other...
