5 results about "Scouring agent" patented technology

This invention provides a phosphorus-free, multifunctional, environmentally friendly scouring agent, its preparation method, and its application, belonging to the field of textile printing and dyeing technology. The surfactants used in this invention (including 2-ethylhexanol alkyl glycoside, 2-propylheptanol alkyl glycoside, 2-propylheptanol xyloside, and isomeric tridecyl alcohol ether carboxylic acid) are all nonionic surfactants. The resulting phosphorus-free, multifunctional, environmentally friendly scouring agent is easily soluble in water, acid-resistant, resistant to high-concentration strong alkalis, hard water-resistant, low-foaming, and has strong penetrating power. It is widely applicable to cotton and its blended textile processes, achieving excellent whiteness and wicking effect in conventional annealing / scouring / bleaching processes. It contains no alkylphenol polyoxyethylene ethers or organophosphates, causing no environmental pollution and simplifying and making textile pretreatment processes more environmentally friendly.

A method for dyeing a fabric has the steps of adding a fabric to a jet dyeing machine containing water, adding a scouring agent to the jet dyeing machine, heating the water and cooling the water, removing the water from the jet dyeing machine and refilling with water, agitating the fabric in the jet dyeing machine, adding a dye, a leveling agent, and a dispersing agent to the jet dyeing machine, heating the refilled water and cooling the refilled water, removing the refilled water from the jet dyeing machine and refilling with water, heating the refilled water to a certain temperature, agitating the fabric in the jet dyeing machine, adding a surfactant to the jet dyeing machine, maintaining the refilled water at the certain temperature and cooling the refilled water, removing the refilled water from the jet dyeing machine and removing the fabric from the jet dyeing machine.

The application discloses a scouring agent composition and a preparation method and application thereof. The scouring agent composition comprises, based on the total weight, 5-15 wt% of rosin-based multi-branched block polyether, 2-6 wt% of polyether modified siloxane, 10-25 wt% of cashew phenol block polyether, 2-10 wt% of polycarboxylic acid chelating dispersant and the balance of water. The scouring agent composition has good wettability, emulsifiability and dispersibility, and is especially suitable for a low-temperature continuous process. The scouring agent composition has low foam, is especially suitable for a high-speed continuous process above 100 m / min, and can further improve production efficiency. In addition, the scouring agent composition adopts bio-based raw materials such as rosin acid and cashew phenol, is easy to degrade, does not contain APEO and phosphorus, and conforms to the sustainable development concept.

This application discloses a low-temperature debleaching and scouring agent and its preparation method. On one hand, this application provides a low-temperature debleaching and scouring agent, wherein the mass ratio of each component of the scouring agent includes: 4-8 parts of fatty alcohol polyoxyethylene ether, 2-10 parts of isomeric alcohol polyoxyethylene ether, 1-4 parts of alkyl glycoside, 2-8 parts of alkylamine ester, 10-16 parts of sodium polyacrylate, and 62-74 parts of deionized water; the scouring agent also includes sodium hydroxide, and the final concentration of sodium hydroxide added is 1.0-1.5%. On the other hand, this application also provides a method for preparing the above-mentioned low-temperature debleaching and scouring agent. This application exhibits excellent degumming, dewaxing, and impurity removal effects, imparting superior wicking effect and whiteness to fabrics, with good environmental friendliness and minimal damage to fabrics.

The invention relates to the technical field of cloth processing, and particularly discloses a slurry-spot-free pretreatment clean dyeing and finishing method for chemical and blended fabrics, which comprises the following steps: (1) soaking the chemical and blended fabrics in a pretreatment solution, transferring the soaked chemical and blended fabrics into a composite desizing solution, and stirring to obtain desized chemical and blended fabrics; (2) putting the desized chemical and blended fabric into a weakly alkaline scouring agent, performing scouring treatment, transferring into a bleaching solution for bleaching, performing flushing treatment, and drying until the water content is less than or equal to 5%, so as to obtain the dried chemical and blended fabric; and (3) putting the dried chemical and blended fabric into a dyeing solution containing dye, carrying out dyeing treatment to obtain a dyed chemical and blended fabric, and carrying out color fixation treatment, water washing and drying on the dyed chemical and blended fabric to obtain the pulp-spot-free chemical and blended fabric. According to the non-slurry-spot pretreatment clean dyeing and finishing method for the chemical fiber fabric, desizing is thorough, refining is uniform, a good foundation is laid for dyeing and fixation, and the application prospect is wide.
