Problems solved by technology

Cheese dyeing is mainly used for yarn-dyed weaving. It is monofilament, single fiber or single yarn dyeing. After dyeing, it is required to be weaved on the machine. Once there is a dyeing quality problem, it can only be re-dyed to black, which will be a great loss to the manufacturer.

Embodiment 1

[0049] The dyeing process of the cashmere cheese yarn is as follows: take the cashmere cheese yarn for quality inspection, after passing the test, put it in a cage, put it into a cylinder, first carry out pretreatment according to the pretreatment process, and then carry out dyeing treatment according to the dyeing process, using a high-frequency dehydrator to 1600r / min rotation speed for dehydration, use radio frequency dryer to dry at a cloth speed of 15m / h, carry out quality inspection, tighten the cylinder, and pack it.

[0050] The pretreatment process is as follows: in the pretreatment solution with a bath ratio of 1:10 at room temperature, firstly add 2% NaHCO3 and 2% oxygen bleach activator tetraacetylethylenediamine (TAED) in the treatment solution, and then heat up to 2%. Treat at 40°C for 60min, add 1% deoxygenase, treat at 40°C for 10min, wash with water at 40°C for 8min, and drain.

[0051] The dyeing process is: 1% MF red 2BL, 1% MF blue GL, 1% MF golden yellow R...

Abstract

The invention provides a cashmere cheese dyeing technology. The method comprises the steps of pretreating the cashmere cheese according to a pretreatment technology, dyeing the cashmere cheese according to a dyeing technology, and finally dewatering and drying the cashmere cheese. Compared with the prior art, the method has the advantages of a high dyeing rate, high homochromatism, perfect color fastness, low cashmere damage, perfect coloring and washing performance and low probability of decoloring and is more suitable for small and medium-sized cashmere cheese dyeing processing factories, and relatively economic and convenient practical operation can be brought to investors with small investment.

Description

technical field [0001] The invention relates to a dyeing process for cashmere cheese. Background technique [0002] The dyeing of cheese yarn is to wind the yarn on a special bobbin (plastic or stainless steel) with porous, string it together, and place it in a closed pressure-resistant container. At a certain temperature, the pressure of the pump makes the The dye flows from the inside of the yarn to the outside through the package, and then flows from the outside to the inside, and penetrates back and forth, so that the dye molecules are combined with the fiber until the package yarn is dyed. Cheese dyeing has the characteristics of short production cycle, quick change of colors, energy saving and dyeing materials, and low pollution. Generally, high temperature and high pressure are used, but this will cause great damage to the cheese fibers. With the development of social economy, people's quality of life and living taste are getting higher and higher, and more people ar...
