Description

Technical Field

[0001] The invention relates to a natural dye dyeing method for textile fabrics, natural dye dyed fabrics and ready-made clothes, belonging to the technical field of textiles. Background Art

[0002] Natural dyes refer to dyes obtained from plants, animals or mineral resources, without artificial synthesis and little or no chemical processing. Because they can be regenerated, they meet the requirements of sustainable development and environmental protection. In addition, most natural dyes are traditional Chinese medicines, which have certain antibacterial functions. Moreover, fabrics dyed with natural dyes have a pure beauty of nature, and they are gradually becoming popular again.

[0003] Conventional natural dye fabric dyeing products are mainly obtained by in-cylinder dyeing in overflow dyeing machines or airflow dyeing machines. Since the dyeing process is an intermittent processing, the process time is long, the process is complicated, and the production efficiency is low. In addition, since the fabric is processed in a rope-like manner in the cylinder, the cloth surface cannot be opened well. In addition, because the molecular weight of natural dyes is large, the diffusion and migration properties are poor, resulting in poor uniformity of the dyed fabric and serious stripe defects after dyeing, which seriously affects the subsequent clothing production.

[0004] Therefore, providing a natural dye dyeing method for textile fabrics and natural dye dyed fabrics and garments has become a technical problem that needs to be solved urgently in the field. Summary of the invention

[0005] In order to solve the above shortcomings and deficiencies, an object of the present invention is to provide a natural dye dyeing method for textile fabrics. The dyeing method provided by the present invention can solve the problems of uneven fabric dyeing color, serious stripe defects and low production efficiency when dyeing fabrics in overflow dyeing machines or gas-liquid dyeing machine cylinders using traditional natural dyes in the prior art.

[0006] Another object of the present invention is to provide a natural dye dyed fabric, which is prepared by the natural dye dyeing method for textile fabrics described above.

[0007] Another object of the present invention is to provide a ready-made garment, which is made from the fabric dyed with the natural dyes described above.

[0008] In order to achieve the above objectives, on the one hand, the present invention provides a natural dye dyeing method for textile fabrics, wherein the dyeing method comprises:

[0009] (1) using a cationic modifier solution to perform cationic modification treatment on a textile fabric to obtain a cationic modified fabric;

[0010] (2) dyeing the cationic modified fabric obtained in step (1) with a natural dye solution or a mixed solution of a natural dye and a mordant, and then rolling the obtained fabric and stacking it to obtain a uniform dyeing effect and excellent color fastness on the fabric, thereby obtaining a dyed fabric;

[0011] (3) washing, soaping, softening, shaping and pre-shrinking the dyed fabric obtained in step (2) to obtain a natural dye dyed fabric.

[0012] As a specific embodiment of the dyeing method described above, before step (1), the fabric may be subjected to pre-treatment and mercerization, etc., and the pre-treatment operation required may be reasonably selected according to the actual situation of the fabric. For example, in some embodiments of the present invention, the pre-treatment includes scouring and bleaching to remove impurities and improve the hygroscopicity of the fabric, and the whiteness value of the fabric obtained after the pre-treatment is controlled between 40-100.

[0013] In step (1) of the present invention, a cationic modifier solution is used to perform cationic modification on the fabric. During the modification process, cationic groups can be introduced into the fabric fibers to enhance the binding force of the fabric fibers to natural dyes (natural dyes are generally anionic dyes), thereby effectively improving the dyeing rate, dyeing depth and color fastness of natural dyes on the fabric fibers.

[0014] As a specific embodiment of the dyeing method described above, the cationic modification treatment in step (1) is carried out on a CPB flat-width cold-batch integrated machine, an overflow dyeing machine or an airflow dyeing machine.

[0015] As a specific embodiment of the dyeing method described above in the present invention, when the cationic modification treatment in step (1) is carried out on a CPB open-width cold stacking integrated machine, after the cationic modification treatment, the obtained fabric is rolled up and stacked, wherein the stacking temperature is 10-80°C and the time is 5-48h.

[0016] Among them, in step (1), the rolling and stacking of the textile fabric after the cationic modification treatment on the CPB flat-width cold-stacking machine can be carried out on an A-frame rolling machine (commercially available conventional equipment, which can be obtained through commercial purchase). In addition, the CPB (cold pad batch dyeing process) flat-width cold-stacking machine used in step (1) is also a commercially available conventional equipment.

Washing and soaping are conventional operation steps and can be reasonably performed according to actual needs and actual conditions on site.

[0023] In the present invention, both the cationic modification treatment and the natural dye dyeing can be performed on the CPB flat width cold stacking integrated machine. In the flat width dyeing process, the natural dye solution or the mixed solution of the natural dye and the mordant is uniformly applied to the fabric by squeezing liquid on the CPB flat width cold stacking integrated machine; and after the natural dye solution or the mixed solution of the natural dye and the mordant is squeezed liquid on the fabric, the fabric needs to be rolled and stacked so that the relevant treatment liquid reacts fully with the fabric fiber, such as cotton fiber, to ensure the dyeing effect and improve the fastness.
