Abstract
The invention discloses a denim accelerating agent. The reactive dye accelerating agent is prepared from, by weight, 10-30 parts of sodium hydroxide, 10-20 parts of polyacrylamide, 20-30 parts of poly-oxalic acid fatty acid esters, 5-10 parts of sodium metasilicate, 5-15 parts of mica powder, 25-40 parts of sodium dodecyl benzene sulfonate, 40-55 parts of plant extracts and 10-30 parts of surfactants. According to the accelerating agent, level dyeing of the reactive dyes is promoted, the technology is greatly simplified, the time is shortened, and the cost and wastewater treatment load are reduced; the accelerating agent is mainly obtained from the plant extracts and is free of poison and environmentally friendly, damage to a worker body cannot be caused, harm to denim is less, and no harm to a human body can be caused when the denim serves as clothes; the accelerating agent is easy and convenient to prepare and suitable for large-scale industrialized popularization.
Description
Technical field
The present invention relates to a kind of accelerant, especially relate to a kind of denim accelerant and preparation method thereof.
Background technology
In life, the plurality of advantages such as denim is because of color nature, comfortable and easy to wear, wear-resisting, good collocation are subject to everybody pursuing, but denim discolouration phenomena is again phenomenon the most general.Denim due to color comparatively dark, dyefastness is poor, then encounter washing, Exposure to Sunlight or physical friction time, dyestuff easily comes off and fades, and not only affects attractive in appearance, and clothes seems shabby; Secondly, denim, owing to fading, makes will separately clean during cleaning clothes, adds workload greatly, and waste resource, loses time.
At present, the dyeing of denim, due to problems such as dye dispersion inequality and dyestuff hydrolysis, makes the denim after dyeing occur that fastness is bad, easily fades and degradation problem under intensity, and dyeing is for present conventional equipment, in dyeing course, there is the problem such as processing technology complexity, time length.And to add accelerant in dyestuff be one of solution to the problems described above.Accelerant by providing the chemical environment different from the fixation alkali such as soda ash, can inhibit activities dyestuff hydrolysis, reduce REACTIVE DYES to the sensitiveness of temperature, and improve the dissolubility of REACTIVE DYES, level-dyeing property and selective.
CN103397539A discloses a kind of REACTIVE DYES promoter, this promoter makes REACTIVE DYES even dyeing effect good, dyestuff use amount is little, decrease the consumption of soda ash, decrease the labour intensity of workman, but containing the material such as ionic liquid and sodium lignin sulfonate in promoter, not only can impact the health of workman, also can the cloth product after dyeing be affected.So find a kind of accelerant that dyestuff can be promoted to paint of pure natural just to seem particularly important.
Summary of the invention
The object of the present invention is to provide a kind of material convenience, be applicable to promote denim accelerant and the simple preparation method of step thereof of the Dry Sack rate of the level dyeing of denim fabric and raising dyestuff.
For reaching this object, the present invention by the following technical solutions:
