Problems solved by technology

More precisely, nylon is dyed with disperse dyes first, and then cotton is dyed with vat dyes (Vat Dye). Therefore, dyes need to be replaced during the process, and the temperature and pH value of different dyes must be adjusted. specific adjustments, still inconvenient

Embodiment Construction

[0017] In order to make the structural features of the present invention and the achieved effects have a further understanding and recognition, preferred embodiments and detailed descriptions are specially used, which are described as follows:

[0018] First, please refer to figure 1 , which is the basic and necessary operation steps of the present invention, which includes:

[0019] Step S1: heating a dye vat from room temperature to a first temperature, the dye vat has a dye and a fabric, and the fabric is a blended or interwoven fabric of nylon fibers and cotton fibers;

[0020] Step S2: maintaining the first temperature to fix the dye to the nylon fiber;

[0021] Step S3: cooling down the dye vat to a second temperature;

[0022] Step S4: maintaining the second temperature to fix the dye to the cotton fiber; and

[0023] Step S5: Taking out and soaping the fabric.

[0024] Wherein, the dye is an acid reactive dye.

[0025] Before operating the method of the present in...

Abstract

The invention provides a one-bath two-step dyeing method of a nylon-cotton fabric. The one-bath two-step dyeing method can realize dyeing of a nylon-cotton blended or knitted fabric by an acid reactive dye in 2 hours. The one-bath two-step dyeing method realizes nylon-cotton fabric dyeing in order by pH value and temperature control in a way that nylon is dyed and then cotton is dyed, and realizes accurate control of one-bath two-step dyeing time thereby ensuring opportune dyeing time and thus finished product dyeing quality is maintained, a color difference between nylon and cotton is avoided and shedding and fading are difficult.

Description

technical field [0001] The invention is a one-bath two-stage dyeing method for fabrics, especially a method for quickly dyeing nylon and cotton blended or interwoven fabrics at one time. Background technique [0002] In the technical field of dyestuffs, each dyestuff has its specific suitability for textile dyeing. For example, acid gold-containing dyes (Pre-metallized Acid Dyes) are mostly used for exhaust dyeing, continuous dyeing and printing of nylon (polyamide) and wool fibers. And other processing, can make different types or types of nylon or wool fibers obtain ideal dyeing results. [0003] However, if the fabric to be dyed is not made of nylon or wool fiber, but a blended or interwoven fabric of nylon and cotton, it is difficult to control the dyeing ability of acid gold-containing dyes on cotton, so reactive dyes (Reactive dyes) are needed. Dye) intervention. Also known as reactive dyes, the molecular structure contains one or more reactive groups, which can chem...
