Embodiment 1

[0023] Present embodiment 1 is a kind of dyeing method of textile fabric, is characterized in that, comprises the steps:

[0024] (1) Soaking, soak the prepared textile fabric in hot water at 70°C for 1 hour to fully expand the fibers in the textile fabric, which is beneficial to the coloring of the textile fabric;

[0025] (2) Desizing, dehydrating and drying the soaked textile fabrics, and then soaking in the desizing solution for 2 hours to remove the size in the textile fabrics. The desizing solution is a desizing enzyme solution, which includes a mass ratio of BH-7658 enzyme, salt, and penetrant JFC water at a ratio of 1:3:2:1000 have a high desizing rate and do not damage fibers. During the desizing process, the textile fabric is stirred once every half an hour to make the textile fabric fully desizing;

[0026] (3) Singeing. After the desized textile fabric is dried, the textile fabric is tensioned and flat-width passed through the gas singeing machine quickly, the tem...

Embodiment 2

[0031] Present embodiment 2 is a kind of dyeing method of textile fabric, is characterized in that, comprises the steps:

[0032] (1) Soaking, soak the prepared textile fabric in hot water at 75°C for 1 hour to fully expand the fibers in the textile fabric, which is beneficial to the coloring of the textile fabric;

[0033] (2) Desizing, dehydrating and drying the soaked textile fabrics, and then soaking in the desizing solution for 2 hours to remove the size in the textile fabrics. The desizing solution is a desizing enzyme solution, which includes a mass ratio of BH-7658 enzyme, salt, and penetrant JFC water at a ratio of 2:4:2:1000 have a high desizing rate and do not damage fibers. During the desizing process, the textile fabric is stirred every half an hour to fully desizing;

[0034] (3) Singeing. After the desized textile fabric is dried, the textile fabric is tensioned and flat-width quickly passed through the gas singeing machine. The temperature is controlled betwee...

Embodiment 3

[0039] Present embodiment 3 is a kind of dyeing method of textile fabric, is characterized in that, comprises the steps:

[0040] (1) Soaking. Soak the prepared textile fabric in hot water at 80°C for 1 hour to fully expand the fibers in the textile fabric and facilitate the coloring of the textile fabric;

[0041] (2) Desizing, dehydrating and drying the soaked textile fabrics, and then soaking in the desizing solution for 2 hours to remove the size in the textile fabrics. The desizing solution is a desizing enzyme solution, which includes a mass ratio of BH-7658 enzyme, salt, and penetrant JFC water at a ratio of 3:5:3:1000 have a high desizing rate and do not damage fibers. During the desizing process, the textile fabric is stirred every half an hour to fully desizing;

[0042] (3) Singeing. After the desized textile fabric is dried, the textile fabric is tensioned and flat-width quickly passed through the gas singeing machine. The temperature is controlled between 900°C a...

Abstract

The invention discloses a method for dyeing a textile fabric. The method comprises the following steps: soaking the prepared textile fabric in a desizing solution for 2 hours, airing the textile fabric subjected to desizing, tensioning the textile fabric to open width and enabling the fabric to rapidly pass through a singeing frame, cooling the textile fabric, immersing in bleaching liquid, allowing standing still for 2 hours, stirring, taking out the fabric and airing, immersing into a dye vat for dyeing, coloring with reactive dyes, and adding an alkaline agent for fixation. The method disclosed by the invention has the beneficial effects that the dyeing time is shortened, and the colorant utilization rate is improved, so that the textile fabric is fully dyed, and the color fastness is excellent.

Description

technical field [0001] The invention relates to the field of dyeing, in particular to a method for dyeing textile fabrics. Background technique [0002] In today's society, the clothing industry and home improvement industry are developing rapidly, and people's demand for fabrics is increasing day by day, and at the same time, certain requirements have been placed on the quality and color of fabrics. [0003] Nowadays, the dyeing technology is changing with each passing day, and the dyeing process mostly relies on machines, but machine dyeing is not flexible, and problems such as chicken paw prints and uneven coloring are prone to occur; The problem of waste water. Contents of the invention [0004] The object of the present invention is to provide a method for dyeing textile fabrics, which has uniform coloring after dyeing, is not prone to chicken paw prints, has excellent color fastness, and improves the utilization rate of dyestuffs. [0005] In order to achieve the a...
