Embodiment 1

[0011] The dyeing method of the cotton spun elastic cloth provided in this embodiment includes the following steps in sequence:

[0012] (1) Scouring and bleaching: After inspecting the original fabric, it is sewn to ensure continuous batch processing; the fabric is quickly passed through the high temperature flame or rubbed over the red hot metal surface to quickly burn the fluff on the cloth surface. To make the cloth surface smooth and beautiful, and to prevent uneven dyeing and printing defects due to the presence of fluff during dyeing and finishing; 3g / L concentration is used under neutral conditions at 50°C and pH 7 Amylase desizing the above fabric in the bleaching machine at a speed of 30m / min. The reason is to facilitate weaving. Textile mills often sizing warp yarns to improve strength and abrasion resistance. These sizes will not only affect the water absorption performance of the fabric. , It will also affect the quality of dyeing and finishing products and increase t...

Embodiment 2

[0016] The dyeing method of the cotton spun elastic cloth provided in this embodiment includes the following steps in sequence:

[0017] (1) Scouring and bleaching: After inspecting the original fabric, it is sewn to ensure continuous batch processing; the fabric is quickly passed through the high temperature flame or rubbed over the red hot metal surface to quickly burn the fluff on the cloth surface. To; under the neutral condition of 50℃ and pH value of 7, use the amylase of 3g / L concentration to desizing the above-mentioned fabric on the bleaching machine at a speed of 35m / min; put the desizing fabric at 3g / Steam in a sodium hydroxide solution of L concentration for 80 minutes, then wash with 85°C hot water (3 cells), then cold wash (4 cells), and finally drop cloth under the condition of pH 7.5 to complete the cooking; A hydrogen peroxide solution with a pH value of 10 is used as a bleaching solution to bleach the above-mentioned simmered fabric at a temperature of 95°C, and...

Embodiment 3

[0021] The dyeing method of the cotton spun elastic cloth provided in this embodiment includes the following steps in sequence:

[0022] (1) Scouring and bleaching: After inspecting the original fabric, it is sewn to ensure continuous batch processing; the fabric is quickly passed through the high temperature flame or rubbed over the red hot metal surface to quickly burn the fluff on the cloth surface. To; under the neutral condition of 50℃ and pH value of 7, use 3g / L amylase in the bleaching machine to desizing the above fabric at a speed of 40m / min; put the desizing fabric at 3g / Steam in a sodium hydroxide solution of L concentration for 80 minutes, then wash with 85°C hot water (3 cells), then cold wash (4 cells), and finally drop cloth at pH 8 to complete the cooking; A hydrogen peroxide solution with a pH value of 10 is used as a bleaching solution to bleach the above-mentioned simmered fabric at a temperature of 95°C, and then add the refining agent DYSTAR at a ratio of 3g ...

Abstract

The present invention discloses a staining method for cotton-silk elastic fabrics. The staining method mainly comprises scouring, bleaching, staining, finishing and other steps. The staining method for cotton-silk elastic fabrics provided by the present invention adopts a production process of continuous pad dyeing according to the characteristics of different raw materials, which can continuously execute production on a large scale, and ensures that the fabric surface of produced products is glabrous, beautiful, and soft in hand feeling. Therefore, the present invention can meet the requirement of consumers.

Description

Technical field [0001] The invention belongs to the technical field of textiles, and particularly relates to a method for dyeing cotton spun elastic cloth. Background technique [0002] Cotton spun elastic cloth is a kind of fabric interwoven with cotton yarn, spun silk and spandex yarn as raw materials. Traditional silk printing and dyeing factories cannot dye cotton spun elastic cloth continuously on a large scale due to the limitation of process technology and equipment, and the cloth surface has a velvety feel, which does not meet the requirements of the market. Therefore, how to continuously dye cotton and spun elastic cloth has always been a new topic for researchers in the textile field. Summary of the invention [0003] In order to solve the above-mentioned problems, the purpose of the present invention is to provide a dyeing method that can use continuous pad dyeing to produce a cotton spun elastic cloth with a smooth and bright surface, a soft hand, good quality and hi...
