Due to the direct collision of dye molecules, they aggregate into larger dye aggregates (or dye associations). These larger dye aggregates are deposited on the fabric during the dyeing process, causing color stains.When dyeing:The free dye molecules will recrystallize during the heating (or cooling)

As direct dyes and other accelerating agents for cotton dyeingWhen dyeing cotton with direct dyes, sulphur dyes, vat dyes and Yindioxin dyes, sodium sulfate can be used as a dye-promoting agent.These dyes are easy to dissolve in the prepared dyeing liquor, but not easy to dye cotton fibers. Because

The maximum working temperature of this kind of proofing machine is 130℃, the heating speed can be adjusted, and two electric heating tubes are used as the heat source. Up to 12 dye cups can be placed, and the hook with the sample is moved up and down by the linkage device to complete the proofing p

Factors affecting the light fastness of dyes 1. The wavelength of the light source and the irradiated light; 2. Environmental factors; 3. The chemical properties and organizational structure of the fiber; 4. Bonding strength between dye and fiber; 5. The chemical

Cold pad-batch dyeing, as a semi-continuous dyeing method, realizes environmentally friendly dyeing of cotton knitted fabrics through processes such as semi-product pretreatment, pad dyeing solution, coiling, stacking, washing, soaping, washing and drying. 1. Pre-processing preparationThe cold pad-b

The development, quality improvement, and upgrade of certain varieties of cotton and its blended knitted fabrics require mercerizing treatment and reasonable selection of mercerizing methods.

Key points of chemical material operation1. Check the accuracy of the prepared dyes and chemicals according to the prescription list. When disperse dyes are used to make materials, generally use cold water to beat them and mix them evenly (stirring with a mixer for about 20-30 minutes), and then dil

Strong, good abrasion resistance, ranking first among all fibers. Its abrasion resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber. Therefore, its durability is excellent.Nylon fabric has excellent elasticity and elastic recovery, but it i

⑴Choose the correct concentration of dye, and make sure to shake the dye evenly before absorbing the dye.⑵Choose a suitable pipette, suck the material accurately, and keep the eyes facing the concave surface of the liquid surface in the tube. After sucking the material, wipe the outer wall of the tu

The reason for Malaysia's "closure of the country" is still the epidemic. According to the epidemic data released by the Ministry of Health of Malaysia, on May 12, Malaysia had 3,807 new confirmed cases in a single day, with a total of more than 440,000 confirmed cases, 17 new deaths that day, and a

The dyeing of nylon fiber mainly uses acid dyes and some disperse dyes. Disperse dyes are mainly used in the case of relatively light colors, and the most used are acid dyes. Acid dyes are divided into level dyeing acid dyes (strong acid acid dyes); semi-level dyeing acid dyes (weak acid acid dyes)
