Problems solved by technology

However, synthetic fibers made by general melt spinning have a relatively simple structure and form, compared with natural fibers, there is still a considerable gap in terms of structure and performance.
[0003] At present, the cross-sectional shapes of special-shaped fibers produced on the market mainly include triangular, trilobal, pentagonal, cross-shaped, flat, C-shaped, T-shaped, etc. The shapes are relatively simple, and the surface gloss of the fibers is poor. Disadvantages such as pilling, poor water absorption, poor bulk, poor hand feeling, and low elasticity

Embodiment 1

[0022] Such as figure 1 , figure 2 , image 3 As shown, a spinneret for producing multi-hollow profiled fibers described in this embodiment includes a spinneret body 1 on which several spinneret holes 2 are arranged, and the spinneret holes 2 include The regular hole structure 6 located at the end of the spinneret body 1 close to the raw material input and the special-shaped mesopore structure located at the end of the spinneret body 1 close to the raw material output, the regular hole structure 6 and the special-shaped mesopore structure communicate with each other and pass through the spinneret The body 1, wherein the shape of the horizontal section of the special-shaped hollow structure 3 is formed by a plurality of sets of double-semi-arc-shaped holes 4 arranged in a straight line, and each set of double-semi-arc-shaped holes 4 is formed by two semi-circular holes spaced opposite each other. , and there is also a gap between two adjacent groups of double-semi-arc-shaped...

Embodiment 2

[0027] This embodiment describes a method for producing multi-hollow special-shaped fibers using the spinneret described in Example 1. The specific production steps are: raw material screening, raw material drying, high temperature melting, spiral extrusion, spinneret ejection, cooling Oiled, coiled and formed.

[0028] The prepared melt is transported to the booster pump through the melt delivery pipeline, cooled by the melt cooler, and then distributed to each spinning box by the distribution valve; metered by the metering pump, the melt is injected into the spinneret assembly and filtered Extruded, and then cooled by ring blowing to obtain primary fibers, every 10 bundles of primary fibers are one, and every two bundles pass through guide wire hooks, oiling devices, guide wire hooks, pre-network, the first hot roller, the second After the hot roll, it enters the winding machine for winding and forming; the temperature of the box during spinning is controlled at 270°C, the p...

Embodiment 3

[0030] This embodiment describes a method for producing multi-hollow special-shaped fibers using the spinneret described in Example 1. The specific production steps are: raw material screening, raw material drying, high temperature melting, spiral extrusion, spinneret ejection, cooling Oiled, coiled and formed.

[0031] The prepared melt is transported to the booster pump through the melt delivery pipeline and cooled by the melt cooler, and then distributed to each spinning box by the distribution valve; metered by the metering pump, the polyester melt is injected into the spinneret assembly Filtration, extrusion, and cooling by ring blowing to obtain primary fibers, every 10 bundles of primary fibers are one, and every two bundles are combined and passed through guide wire hook, oiling device, guide wire hook, pre-network, first heating roller, The second hot roll enters the winding machine for winding and forming; the temperature of the box during spinning is controlled at 2...

Abstract

The invention relates to the technical field of fiber production, in particular to a spinneret plate for producing multi-hollow special-shaped fibers. The spinneret plate comprises a spinneret plate body, a plurality of spinneret orifices are formed in the spinneret plate body, each spinneret orifice comprises a regular porous structure located at the end, close to the raw material input end, of the spinneret plate body and a special-shaped hollow structure located at the end, close to the raw material output end, of the spinneret plate body, and the regular porous structures and the special-shaped hollow structures are communicated and are communicated with the spinneret plate body. A production method for the multi-hollow special-shaped fibers adopting the spinneret plate comprises the specific production steps of raw material screening, raw material drying, high-temperature melting, spiral extruding, spinneret plate spraying-out, cooling and oiling and wind forming. According to thespinneret plate for producing the multi-hollow special-shaped fibers and the production method, the produced multi-hollow special-shaped fibers have the advantages of being high in fluffiness, good in elasticity, high in heat retention property, soft and smooth in hand feeling, good in rebound resilience, good in spreadability and the like.

Description

technical field [0001] The invention relates to the technical field of fiber production, in particular to a spinneret for producing multi-hollow special-shaped fibers and a production method. Background technique [0002] Since the synthetic fiber came out in the 1940s, it has been favored by people for its incomparable advantages, such as: high elasticity, corrosion resistance, and no fear of insects, etc., and has developed rapidly. With the increase of new functions of synthetic fibers and the continuous improvement of added value, textiles and industrial products made of synthetic fibers are becoming more and more popular. However, synthetic fibers produced by general melt spinning have a relatively simple structure and form, compared with natural fibers, there is still a considerable gap in terms of structure and performance. [0003] At present, the cross-sectional shapes of special-shaped fibers produced on the market mainly include triangular, trilobal, pentagonal, ...
