Embodiment 1

[0040] The device for preparing cellulose fiber cheese yarns for on-line dyeing of color dot yarns of the present invention includes dyeing components, which are composed of dyeing tank 5, dyeing runner 2, motor 6 and yarn pressing rod 3, and the dyeing component is located in the overfeeding device Between 4 and the yarn break automatic stop sensor 1, the motor 6 is connected to the dyeing runner 2 through a rotating shaft. The dyeing runner 2 is located in the dyeing tank 5. The yarn 7 passes through the overfeeding device 4 and is connected to the yarn break automatic stop sensor 1. The pressure rod 3 presses the yarn 7 on the dyeing wheel 2.

[0041] The diameter of the dyeing wheel 2 is 5 cm.

[0042] The dyed yarn adopts 25tex pure cotton yarn. The style of the dyeing wheel is a smooth circular cross section, and the diameter of the wheel is 5cm.

[0043] The method for preparing cellulose fiber cheese yarn dyed on-line color dot yarn of the present invention includes the foll...

Embodiment 2

[0049] The cellulose fiber cheese in-line dyeing color dot yarn preparation device described in Example 2 is the same as that in Example 1, except that the dyeing wheel 2 has a tooth-shaped cross section, and the specific style is as attached figure 2 As shown, the diameter of the dyeing wheel 2 is 7 cm.

[0050] The dyed yarn adopts 14.5tex cotton / tencel (50% / 50%) blended yarn.

[0051] The method for preparing cellulose fiber cheese yarn dyed on-line color dot yarn of the present invention includes the following steps:

[0052] The preparation of the dye solution: The dye is selected as Sumitomo medium temperature dye blue-red R3BF (double reactive group dye, monochloros-triazine and vinylsulfone group), and the mass ratio of n-propanol, water and reactive dye is 50:45: 5.

[0053] The pretreatment of pure cotton cheese yarn: the cellulose fiber cheese yarn is pretreated by a cheese yarn dyeing machine. The amount of sodium carbonate and cationic fixing agent used in the pretreatme...

Embodiment 3

[0057] The cellulose fiber cheese yarn in-line dyeing color dot yarn preparation device described in Example 3 is the same as that in Example 1, except that the specific pattern of the zigzag section of the dyeing wheel 2 is as attached image 3 As shown, the diameter of the dyeing wheel 2 is 9 cm.

[0058] The dyed yarn uses 20tex flax fiber yarn.

[0059] The method for preparing cellulose fiber cheese yarn dyed on-line color dot yarn of the present invention includes the following steps:

[0060] The preparation of the dye solution: The dyes are respectively selected as Sumitomo medium temperature dyes blue B-4R (monofluoros-triazine reactive dyes) and red R3BF (double reactive dyes, monochloros-triazine and vinylsulfone based), alcohol solvents are selected For the mixed solution of ethanol and glycerol (the mass ratio of the two is 3:1), the mass ratio of the alcohol solvent, water, and reactive dye is 60:36:4.

[0061] Pretreatment of pure cotton cheese yarn: pretreatment of ce...

Abstract

The invention belongs to the technical field of textile dyeing and finishing, and particularly relates to a preparation device and a preparation method of a cellulose fiber cheese on-line dyed speck yarn. The preparation device comprises a dyeing assembly, wherein the dyeing assembly is composed of a dyeing groove, a dyeing rotating wheel, a motor and a yarn pressing rod; the dyeing assembly is located between an overfeeding device and a yarn breaking automatic-stop sensor; the motor is connected with the dyeing rotating wheel through a rotating shaft; the dyeing rotating wheel is located in the dyeing groove; and a yarn penetrates through the overfeeding device and is connected with the yarn breaking automatic-stop sensor, and the pressure rod presses the yarn on the dyeing rotating wheel. According to the method, the production of the speck yarn is realized by virtue of an alcohol solvent and a water dyeing liquid in a winder, so that the production cost of the speck yarn can be remarkably reduced while the salt-free dyeing of the cellulose fiber yarn is realized, and the dyeing process is green, environmentally friendly and controllable.

Description

Technical field [0001] The invention belongs to the technical field of textile dyeing and finishing, and in particular relates to a preparation device and method for on-line dyeing of cellulose fiber cheese yarns. Background technique [0002] With the continuous improvement of people's aesthetic concepts and demand for fashionable lifestyles, consumers have also put forward higher and higher requirements for the patterns of fabrics woven by traditional colored yarns. However, it is difficult to make further qualitative breakthroughs in the style of woven fabrics limited by a single color of a single yarn. In this context, differentiated yarns such as colored spinning yarns and colored dotted yarns have appeared on the market. However, the production and processing of these yarns have problems such as complex production processes, high energy consumption, and serious environmental pollution. . [0003] Patent CN201210314317.3 discloses a new type of colored dot yarn and its produ...
