Embodiment 1

[0020] Such as Figure 1-2 As shown, the double-layer structure yarn dyeing tube with a certain elastic deformation ability on the surface of the present invention is divided into an inner layer 1 and an outer layer 2 arranged concentrically, and the inner layer 1 is a cylindrical hollow cheese with a through hole 3 Dyeing tube, the outer layer 2 is a wave-shaped embossed mesh with elastic deformation capability, the upper and lower parts of the inner layer 1 are provided with semi-arc-shaped grooves, and the upper and lower parts of the outer layer 2 are provided with semi-arc-shaped protrusions for assembly. The outer layer 2 closely contacts and completely covers the yarn winding area of ​​the inner layer 1 . Because the pH value of the cheese dyeing solution is 2-14, hydrogen peroxide and other oxidizing agents need to be added during the dyeing process. Therefore, the outer layer 2 is a wavy roll with a plain weave structure interwoven with acid-resistant, alkali-resistan...

Embodiment 2

[0025] On the basis of Example 1, the surface has a double-layer structure dyeing tube with a certain elastic deformation capacity. The mesh of the wave-shaped embossed net is a square, the side length is 3mm, and the diameter of the steel wire is 0.5mm. 33% of the mesh area, the number of outer layer 2 coating layers is 1 layer.

[0026] Use the double-layer structure dyeing bobbin in Example 2 and the traditional cheese dyeing bobbin to dye the 40S / 1FFT elastic yarn in the same dyeing vat, and the cheese density is 3.9g / cm 3 , The color difference and elasticity comparison data of the inner and outer layers of the yarn after dyeing are shown in Table 1:

[0028]

Embodiment 3

[0030] On the basis of Example 1, the surface of this example has a double-layer structure dyeing tube with a certain elastic deformation capacity. The mesh of the wave-shaped embossed net is square, the side length is 15mm, and the diameter of the steel wire is 0.8mm. Accounting for 11% of the area of ​​the crimped wire mesh, the number of outer layer 2 cladding layers is 3.

[0031] Use the double-layer structure dyeing bobbin in Example 3 and the traditional cheese dyeing bobbin to dye 50S / 1 Lycra yarn in the same dyeing vat, and the cheese density is 4.2g / cm 3 , The color difference and elasticity comparison data of the inner and outer layers of the yarn after dyeing are shown in Table 2:

Abstract

The invention relates to the technical field of textile equipment, in particular to a double-layer structured yarn-dyeing tube with a certain elastic deformability in the surface, which includes an inner layer and an outer layer which are concentrically arranged; the inner layer is a cylindrical hollow cheese-dyeing tube with a through hole, and the outer layer is a corrugated crimped net with elastic deformability. According to the invention, the corrugated stainless steel crimped net is additionally arranged on the surface of a yarn winding area of the yarn-dyeing tube, so that inner yarns have a larger shrinkage space when the yarns are subjected to cheese dyeing, the density difference between the inner yarns and outer yarns is reduced, and the technical problems of large color difference and inconsistent elasticity of the inner yarns and outer yarns in the cheese dyeing are solved.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a yarn dyeing bobbin with a double-layer structure whose surface has a certain elastic deformation capacity. Background technique [0002] The dyeing bobbin is a bobbin with a through hole for winding the yarn during dyeing. When dyeing, the yarn is wound on the dyeing bobbin. After dyeing, the dyeing bobbin is placed in the dyeing vat for dyeing. Influenced by factors such as water quality, head of dyeing machine pump, dyestuff, quality of dyeing tube and small surface elastic deformation, color difference and elastic inconsistency appear in the inner and outer layers of cheese dyed yarn. [0003] In order to solve the above problems, the patent application number is 201320710445X, and the utility model patent titled "dyeing tube" discloses a dyeing tube. Larger through holes make the water permeability higher, thus solving the problem of color difference between the ...
