Embodiment Construction

[0037] like figure 1 Shown is a continuous dyeing process of vulcanized white core colored yarn. The yarn is dyed with sulfur dye and then oxidized in ventilated air. Dyed yarn for denim fabric. Before dyeing with sulfur dyes, the yarn is firstly balled, and the dyed yarn after the drying step is divided and warped, and then the tube is made.

[0038] Process steps of sulfur dyeing:

[0039] 1) Yarn penetration;

[0040] Carry out infiltration treatment in the yarn assorted 100g / liter caustic soda;

[0041] 2) Padding dye:

[0042] The yarn is pad-dyed in a sulfur dye at 90°C±2°C;

[0043] 3) Ventilated air oxidation:

[0044] The dyed yarn is oxidized by ventilation air, and the ventilation oxidation time is about 1 minute;

[0045] 4) Padding dye:

[0046] The yarn oxidized by ventilated air is again pad-dyed in sulfur dye at 90°C±2°C;

[0047] 5) Ventilated air oxidation:

[0048] The dyed yarn is oxidized by ventilation air, and the ventilation oxidation time is ...

Abstract

The invention relates to the technical filed of white-core color yarn dyeing, in particular to a continuous dyeing process for curing white-core color yarn and equipment and a fabric thereof. The continuous dyeing process is as follows: the yarn is dyed with sulfur dyes and subjected to ventilated air oxidation, and is then dyed with sulfur dyes and subjected to ventilated air oxidation again, thus obtaining the color yarn for denims having a white core in the middle through dyeing. The fabric is formed by weaving the color yarn obtained by the dyeing process. The continuous dyeing equipment comprises a permeability device, a curing dyeing device, a ventilated air oxidation device, a curing dyeing device, a ventilated air oxidation device, a pickling device, an oxidation device, a yarn post-treatment device and a drying device which are sequentially arranged to form the whole yarn continuous dyeing equipment. The invention has the advantages that: knitted denims with different colors can be produced; the color fastness of the color yarn is high; the color does not fade after washing; and the denims can be washed together with any other fabric and can be washed into jeans having various obsolescence senses.

Description

technical field [0001] The invention relates to the technical field of white core colored yarn dyeing, in particular to a continuous dyeing process of vulcanized white core colored yarn and its equipment and fabrics Background technique [0002] Denim clothing is a kind of fashion clothing. It is comfortable to wear, elegant in appearance, and has a style that gets older and fades more and more after washing. It is a kind of clothing that consumers like. Last year, the national denim fabric production output was 3.1 billion meters. However, its production is limited due to its high cost, high equipment requirements and large investment. The current output accounts for less than 0.5% of the entire denim industry. [0003] Currently produced denim fabrics include knitted denim, which are mainly made of indigo yarn. Due to the low dye uptake of indigo, the dye is deposited on the surface of the fiber and faded by washing. In the washing of clothes after wearing, it cannot be...
