Embodiment Construction

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 4 As shown, several spinneret holes 1 are evenly distributed on the spinneret 10 of the present invention for producing composite hollow viscoelastic fibers with three-component special-shaped cross-section, and the spinneret holes 1 include guide holes 11 and micropores 12 that penetrate up and down. , the cross-sections of the guide hole 11 and the microhole 12 are composed of two inner arc-shaped waist holes (111, 111') and two outer arc-shaped waist holes (112, 112'), and the two inner arc waist holes The waist holes (111, 111') are symmetrically arranged and the centers of the two inner arc waist holes are close to each other, and the outer arc waist holes (112, 112') are respectively located at the The outer side is arranged parallel to the arc of the adjacent inner arc-shaped waist hole (111, 111...

Abstract

The invention discloses a production process for a three-component composite hollow viscoelastic fiber with a specially-shaped section. The production process comprises the following steps: by taking high-viscosity melt, low-viscosity melt and low-melting-point melt as raw materials, and adopting a special spinneret plate, spinning; after the high-viscosity melt, the low-viscosity melt and the low-melting-point melt are sprayed out of the spinneret plate, separately bonding the high-viscosity melt and the low-viscosity melt which flow through four end parts of two inner arc-shaped waist holes, bonding the high-viscosity melt and the low-viscosity melt which flow through the same inner arc-shaped waist hole, thereby forming a cavity by the high-viscosity melt and the low-viscosity melt which flow through two inner arc-shaped waist holes, adhering low-melting-point melt which flows through an outer arc-shaped waist hole in a hollow tube formed by the high-viscosity melt and the low-viscosity melt; cooling, loading oil, stretching and winding, thereby obtaining a precursor fiber of the three-component composite hollow viscoelastic fiber with the specially-shaped section; and obtaining the three-component composite hollow viscoelastic fiber with the specially-shaped section and having different length outlines through different back spinning processes.

Description

technical field [0001] The invention relates to the field of fiber preparation technology, in particular to a production technology, equipment and products of a three-component special-shaped cross-section composite hollow viscoelastic fiber. Background technique [0002] Non-woven fabric (English name: Non Woven), also known as non-woven fabric, is a new generation of environmentally friendly materials. It is widely used in the production of medical and sanitary cloth, home decoration cloth, heel cloth, industrial filter material, crop protection cloth, space cotton, heat preservation and sound insulation material, tea bags and other products. [0003] The processing method of non-woven fabrics is usually to orientate or randomly arrange short textile fibers or filaments to form a web structure, and then reinforce them by mechanical, thermal bonding or chemical methods. For example, bonding hollow fibers with bulkiness and resilience with chemical adhesives, or mixing exis...
