Method for preparing dry-type water-soluble colorful rock slices

The invention relates to a preparation method for a dry-type water colored sliver, comprising following technical steps: 1) preparation of polyurethane modification acrylic acid latex: dihydric alcohol is put into a reactor and then temperature is increased to 70 DEG C to 100 DEG C, then dihydric alcohol and organic tin dihydric alcohol is added and temperature is increased to 100 DEG C +/- 5 DEG C for 2 to 4 hour reaction, then temperature is decreased to 60 DEG C +/- 5 DEG C and methyl acrylate and dihydroxy methylpropanoic acid are added, then circumfluence temperature is controlled at 60 DEG C to 80 DEG C and reaction is carried out for 6 hours +/- 0.5 hours; when NCO value in reaction system is lower than 1, prepolymer is transferred into a dispersator and is dispersed in water dissolved in neutralizing agent of triethylamine, then water polyurethane is prepared; 50 to 100 pieces of water polyurethane are put into a reactor, temperature is increased to 70 DEG C to 90 DEG C and polyurethane modification acrylic acid co polymerization latex is obtained: step 2, the preparation of dry-type water colored sliver. The dry-type water colored sliver of the invention has the advantages of fine climate resistance performance, no conglutination on the way of transportation, fine elasticity, no discharging of organic matter with volatility and cost saving.

Dyeing process of polyester cotton fiber fabric

The invention provides a dyeing process of a polyester cotton fiber fabric. The dyeing process comprises the following steps of preforming, pretreatment, drying, dyeing, washing, soaping, color fixing, drying, forming and winding. According to the dyeing process, a high-temperature leveling agent is added during dyeing, so that the problem that level dyeing effect and penetration dyeing effect are affected and even generate color dots and color patches occur caused by gathering of dyes because the heat stability resistance of fuel is reduced due to temperature increase is avoided, and the dyeing effect is good; the temperature is increased in a stepped progressive mode in the dyeing procedure, and the temperature increase and decrease velocity and the dyeing time are strictly controlled, so that high dyeing fastness, dyeing uniformity and good dyeing stability of the polyester cotton fiber fabric are achieved; the dyes with single property are not used and dispersed dyes and neutral dyes are compounded in the dyeing procedure, and the dispersed dyes and the neutral dyes supplement each other, so that good dyeing fastness is achieved; the traditional two-bath two-step method dyeing is abandoned, and the one-bath one-step method dyeing is adopted, so that the energy is saved, and the emission amount is reduced.

High-emulation bamboo joint longitude and latitude heterochromatic textile and preparation method thereof

The invention provides a high-emulation bamboo joint longitude and latitude heterochromatic textile which is woven by organzines and filling yarns, wherein the organzines comprise organzines A and organzines B, the organzines A are formed by the means that covering yarns with granularity of 32 inches are covered into spandex with 40 deniers and spun in a twisting way, the organzines B are formed by the means that covering yarns with granularity of 21 inches are covered into spandex with 40 deniers and spun in a twisting way, the covering yarns consist of cation polyster fiber with the weight percentage of 65% and viscose with the weight percentage of 35%, the filling yarns comprise filling yarns A and filling yarns B, the filling yarns A are formed by twisting the triangular abnormal-shape dacron filament which is formed by 84 single fibers and has the fineness of 150 deniers with the spandex with 40 deniers after air covering, and the filling yarns B are formed by the triangular abnormal-shape dacron filament which is formed by 84 single fibers and has the fineness of 150 deniers. The invention further discloses a preparation method of the textile. Compared with the prior art, the textile has the advantages of being abrasion-resistant, anti-wrinkle, good in size stability, good in color fastness, good in moisture absorption and air permeability, and good in elasticity.

Manufacturing process for indigo dye and blue-dyed printed fabric

The invention discloses a manufacturing process for an indigo dye and a blue-dyed printed fabric. The indigo dye is manufactured by the following components in percentage by weight: 20 to 25 percent of indigo, 16 to 18 percent of sodium carbonate aqueous solution, 3 to 5 percent of quick lime, 7 to 8 percent of rice wine, 5 to 6 percent of fresh pig blood, 5 to 6 percent of tea tree stem ash, and the balance of water. According to the manufacturing process, the ash which is manufactured by adopting tea tree stems which specifically exist in the Jiangnan area replaces the conventional ash manufactured by fern leaves or artemisia vulgaris, so that the colour fastness of a dyed fabric is high; the colour is bright; the process flow is short; the operation is convenient; the cost is low. The manufacturing process has the advantages that the dyed colour is bright; the colour fastness is high; the colour does not fade; the fabric can be washed together with white clothes; the process is simple; the cost is low; the operation is convenient; the dye can be reutilized; emission is avoided; the environment is not polluted. The manufacturing process has particularly outstanding effects when the manufacturing process is used in the conventional blue-dyeing technologies, such as tie-dyeing, wax-dyeing and clamp-dyeing.

Natural-fiber artificial leather and manufacturing method thereof

The invention relates to the technical field of leather processing, in particular to natural-fiber artificial leather and a manufacturing method thereof. The natural-fiber artificial leather is obtained through the following processing steps: opening, carding and dry-process needling treatment is sequentially conducted on natural fibers to obtain a needled non-woven base layer with a fiber net structure inside; by adopting a microwave dyeing method, the needled non-woven base layer is dyed with a chemical dye in a permeating way to obtain gray artificial leather; the upper surface layer of thegray artificial leather is sequentially coated with a bottom sealing layer, a first resin layer, a second resin layer and an oil wax layer in a rolling way, and polishing is carried out to obtain thenatural fiber artificial leather. By adopting the processing technology, energy is saved, emission is reduced, the method is friendly to the environment, the processed artificial leather has excellent washing fading performance and frictional fading performance and good dyeing firmness, the yellowing resistance and aging resistance reach the standard, and various mechanical properties such as tensile strength, tearing strength and elongation are all higher than the index requirements.

Fabric cleaning, printing and dyeing process

The invention discloses a fabric cleaning, printing and dyeing process. The process comprises a pre-treatment procedure, a dyeing procedure and a post-treatment procedure. According to the fabric cleaning, printing and dyeing process, the process of pre-treating fabric by a solution formed by mixing an anhydrous ethanol organic solvent and a desizing agent and a solution formed by mixing an anhydrous ethanol organic solvent and a bleaching agent is adopted, and the problems that in a traditional fabric pretreatment process, the water consumption amount is large, recycling is difficult, and pollution is serious are solved; moreover, along with the decomposition and removal of pectin substances and other substances in fibers, the interfiber space is increased, the internal passages of the fibers are opened, the fabric shows the capillary effect of fluffy and soft hand feeling and uniformity, and subsequent dyeing and finishing processing is better facilitated; by adding the anhydrous ethanol organic solvent, a sizing agent and natural impurities can be better in contact with the desizing solution and the bleaching solution to achieve the removal purpose within a short time, the waterconsumption amount in the pre-treatment process can be greatly reduced, and the energy is saved.
