Problems solved by technology
Fabrics need to be coated and dyed during the production process. Most of the traditional wash-and-fading processes are dyed first and then coated, which looks unnatural. Therefore, we need a new wash-and-fading process that first coats and then dyes. To solve the above problems and meet people's needs

Embodiment 1
[0015] A wash-out style process of first coating and then dyeing, including the following steps:
[0016] A. Selection of gray cloth: There are three main points in the selection and preparation of gray cloth: gray cloth inspection, cloth turning and seam head;
[0017] B. Pre-treatment of gray cloth: the gray cloth of cotton linen is finalized by desizing, boiling and bleaching process;
[0018] C. Coating: Use 20% solid content PU glue on the gray cloth treated in the above steps, and coat it at a temperature of 160 ° C on the coating machine;
[0019] D. Dyeing: The paint dyeing production process is carried out on the padder with paint, including preparation of fuel, padding dyeing solution, infrared pre-baking, hot air drying and baking. The temperature of the hot air drying is controlled at 70°C. The above baking setting is 180℃×30S;
[0020] E. Enzyme washing: The steps of using enzyme washing are as follows:
[0021] 1) Enzyme treatment stage: Throw the combined sam...

Abstract
The invention discloses a first-coating and second-dyeing washed-out style process. The first-coating and second-dyeing washed-out style process comprises the following steps: A, selecting gray cloth: selecting and preparing the gray cloth according to the following three points: checking the gray cloth, overturning the cloth and sewing an end; B, pre-treating the gray cloth: treating the all-cotton and hemp-cotton gray cloth through a desizing and boiling-bleaching process; C, coating: coating the gray cloth treated by the step above by utilizing PU (Polyurethane) glue with the solid content of 20 percent on a coating machine at 160 DEG C; D, dyeing: carrying out a paint dyeing production process on a padder by utilizing paint, wherein the paint dyeing production process comprises the steps of preparing fuel, padding a dyeing solution, pre-drying by infrared rays and baking, the temperature for drying by hot air is controlled to be 70 DEG C to 90 DEG C and the step of baking is carried out 180 DEG C for 30s; E, carrying out water washing with an enzyme, wherein the step of carrying out the water washing with the enzyme comprises the following steps: an enzyme treatment phase and inactivation treatment. The first-coating and second-dyeing washed-out style process breaks through a conventional production process; after the coating is used firstly, dyeing is carried out, so that a pure natural effect can be generated after the cloth is washed out.
Description
technical field [0001] The invention belongs to the technical field of fabric production, and in particular relates to a wash-out style process of first coating and then dyeing. Background technique [0002] Cloth is a commonly used material in decorative materials. Including chemical fiber carpets, non-woven wall coverings, linen cloth, nylon cloth, colored tape, flannel and other fabrics. Cloth plays a considerable role in the decorative display, and is often the main force that cannot be ignored in the entire sales space. Extensive use of fabrics for wall decoration, partitions, and background treatment can also form a good commercial space display style. From the weaving method, it can be divided into two categories: woven fabric and knitted fabric. From the processing technology, it can be divided into: gray cloth, bleached cloth, dyed cloth, printed cloth, yarn-dyed cloth, mixed process cloth (such as printing on yarn-dyed cloth, composite cloth, flocking cloth, imi...
