Problems solved by technology
[0005] The disadvantages of polyester-cotton fabrics are: the polyester fiber in polyester-cotton belongs to hydrophobic fiber, which has a strong affinity for oil stains and is easy to absorb oil stains. Moreover, it is easy to generate static electricity and absorb dust during wearing. It is difficult to wash, and it cannot be ironed with high temperature. soak in boiling water
[0006] In addition, the polyester-cotton fabric prepared by the prior art also has the disadvantages of low color fastness and easy fading, so it is necessary to improve the existing printing and dyeing process of the polyester-cotton fabric

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0029] refer to figure 1 , a polyester-cotton fabric printing and dyeing anti-fading process, the process comprises the following steps:
[0030] S1. Raw fabric preparation; prepare polyester-cotton fabric with a door width of 140CM, a yarn count of 40*40, and a warp and weft density of 133*72;
[0031] S2. Singeing; remove fluff layers of different lengths on the surface of the cloth;
[0032] S3. Desizing: the PVA and other sizing in the cloth body expands in hot alkali, changes from a gel state to a swelling state, and becomes loose after being adhered to the fiber, and then mechanically causes the PVA and other sizing to fall off the fabric;
[0033] S4. Scouri...

The invention discloses an anti-fading processing technology for printing and dyeing a polyester-cotton fabric. The technology comprises the following steps of S1, preparing a gray fabric: preparing the polyester-cotton fabric with the fabric width of 140 cm, the yarn count of 40*40 and the warp and weft density of 133*72; S2, performing singeing: removing fluff layers with different lengths on the surface of a fabric body; S3, performing desizing: enabling a sizing agent such as PVA to fall off from the fabric under the mechanical action after the sizing agent such as the PVA in the cloth body expands in hot alkali, is converted to be in a swelling state from a gel state and is adhered to fibers to become loose; S4, performing boiling: putting the fabric body into high-temperature alkali liquor for boiling, and washing the fabric body with water to remove impurities; S5, performing bleaching: removing pigments on the fabric body by adopting a sodium chlorite method; and S6, performing dyeing: putting the fabric body into dye, controlling the temperature and the pH value, and adding an anti-decolorizing agent, so that the fabric is gradually dyed with the dye. According to the processing technology in the scheme, the color fastness of the polyester-cotton fabric can be improved, the dye and the fibers are firmly combined, and the anti-fading capacity of the fabric is improved.
Description
technical field [0001] The invention relates to the technical field of fabric printing and dyeing, in particular to a polyester-cotton fabric printing and dyeing anti-fading processing technology. Background technique [0002] Fabric printing and dyeing is also called dyeing and finishing. It is a processing method, and it is also a general term for pretreatment, dyeing, printing, finishing, washing, etc. [0003] Polyester-cotton fabrics refer to polyester-cotton blended fabrics, with polyester as the main component, textiles woven with 60%-67% polyester and 33%-40% cotton blended yarns. Polyester-cotton fabrics are commonly known as cotton denim. [0004] Polyester-cotton fabric highlights the style of polyester and has the advantages of cotton fabric. It has good elasticity and wear resistance under dry and wet conditions, stable size, small shrinkage, and has the characteristics of tall and straight, not easy to wrinkle, easy to wash, and quick-drying. features.
