Embodiment 1

[0039] A kind of polyester-cotton disperse / reactive dye fixation and anti-ultraviolet one-bath processing method involved in the present embodiment comprises the following steps: selecting fabric, singeing, desizing, scouring, bleaching, mercerizing, presetting, dyeing and Anti-ultraviolet one-bath finishing, soaping, color fixing, and setting.

[0040] In the step S1 of selecting the fabric, the cotton content in the selected polyester-cotton fabric is 35-60%. Both the warp and weft of the selected fabrics use polyester-cotton blended yarns, specifically polyester-cotton 65 / 35, and the fineness of the polyester-cotton blended yarns used is 32.

[0041] In step S2 singeing, adopt the method of singeing the front and back sides of the natural gas singeing machine to carry out singeing treatment to the selected fabric, the flow rate of natural gas during singeing is 1 cubic meter per hour, and the vehicle speed is 120 meters per minute; The distance from the weaving is 10mm, ke...

Embodiment 2

[0051] A kind of polyester-cotton disperse / reactive dye fixation and anti-ultraviolet one-bath processing method involved in the present embodiment comprises the following steps: selecting fabric, singeing, desizing, scouring, bleaching, mercerizing, presetting, dyeing and Anti-ultraviolet one-bath finishing, soaping, color fixing, and setting.

[0052] In the step S1 of selecting the fabric, the cotton content in the selected polyester-cotton fabric is 35-60%. Both the warp and weft of the selected fabrics use polyester-cotton blended yarns, specifically polyester-cotton 55 / 45, and the fineness of the polyester-cotton blended yarns used is 40 counts.

[0053] In step S2 singeing, adopt the method of singeing the front and back sides of the natural gas singeing machine to carry out singeing treatment to the selected fabric, the flow rate of natural gas during singeing is 1 cubic meter per hour, and the vehicle speed is 110 meters per minute; The distance from the weaving is 9...

Embodiment 3

[0063] A kind of polyester-cotton disperse / reactive dye fixation and anti-ultraviolet one-bath processing method involved in the present embodiment comprises the following steps: selecting fabric, singeing, desizing, scouring, bleaching, mercerizing, presetting, dyeing and Anti-ultraviolet one-bath finishing, soaping, color fixing, and setting.

[0064] In the step S1 of selecting the fabric, the cotton content in the selected polyester-cotton fabric is 35-60%. Both the warp and weft of the selected fabrics use polyester-cotton blended yarns, specifically polyester-cotton 40 / 60, and the fineness of the polyester-cotton blended yarns used is 45 counts.

[0065] In step S2 singeing, adopt the method of singeing the front and back sides of the natural gas singeing machine to carry out singeing treatment to the selected fabric, the flow rate of natural gas during singeing is 0.8 cubic meters per hour, and the vehicle speed is 100 meters per minute; The distance from the weaving i...

Abstract

The invention discloses a color fixing anti-ultraviolet one bath process processing method for a dacron-cotton dispersive / active dye. The method comprises the following steps: selecting a shell fabric; singeing; desizing; boiling off; bleaching; mercerizing; pre-setting; dyeing and anti-ultraviolet one bath process finishing; soap washing and color fixing; and setting. According to the color fixing anti-ultraviolet one bath process processing method for the dacron-cotton dispersive / active dye, a cold dome method is used for desizing and bleaching, so that influence of temperature to the shellfabric can be reduced. Benzyl alcohol is used as a low-temperature dyeing carrier, so that the dye has plasticizing and expanding performance to dacron. A neutral color fixing active dye is dyed favorably at a certain amount. By adopting a reasonable process, a dacron-cotton fabric one bath low-temperature dyeing process can be achieved by adopting a reasonable process, and the dyefastness can achieve the service performance.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing of textile fabrics, in particular to a polyester-cotton disperse / reactive dye fixation and anti-ultraviolet one-bath processing method. Background technique [0002] Polyester-cotton blended fabric is an important fabric for summer clothing, which can be dyed with disperse / direct dyes, disperse / vat dyes, and disperse / reactive dyes. However, the color fastness of fabrics dyed with disperse / direct dyes is poor, and disperse / vat dyes usually need to be dyed in two baths, and disperse / reactive dyes are the most widely used for dyeing polyester-cotton fabrics. [0003] Disperse / reactive dyeing of polyester and cotton fabrics can be carried out in one bath and two baths. The two-bath dyeing method has stable product quality and has no special requirements for dyes. The one-bath method requires the use of alkali-resistant disperse dyes and common reactive dyes or common disperse dyes and ne...
