Description

A kind of clean-out system of removing dyeing and printing loose color

The present invention relates to the Chemicals field, especially a kind of loose colour clean-out system is applicable to the cleaning of cotton and polyester-cotton fabric dyeing and printing loose colour.

In reactive dyestuffs or vat dyes fixation during the stage, hydroxide ion in dyestuff and the dye bath or be adsorbed on the hydroxide ion reaction on the fiber and make dyestuff be hydrolyzed to hydrolised dye, hydrolised dye has the avidity close with reactive dye, can be adsorbed by fiber, but colour fastness is low, promptly causes the loose colour on the fabric.For this reason, in water washing process, use certain detergent, to remove hydrolysis (alcoholysis) dyestuff and other dyeing and printing auxiliary on the fabric.But, in cleaning process along with not because of dyestuff from fabric, transfer to the bath gradually, formation has the dye bath condition of finite concentration, certain temperature and certain hour, cause dyestuff by between the coloured differently of the washing fabric part, bathe and shift mutually by washing, particularly from the transfer of coloured moiety to colourless part, the promptly so-called situation of staiing in vain.In various tensio-active agents, be used to do soap at most at present, consumption is big, and not anti-hard water, washes the serious and Boardy Feeling of back fabric staining; Foam was more when synthetic detergent was adopted in the back, and white contamination situation is not improved.

The purpose of this invention is to provide and a kind ofly have efficient washing ability and can effectively prevent the dyeing and printing loose color clean-out system that stains again whitely.

Technical scheme of the present invention is; Adopt the nonionic surface active agent of polyethenoxy ether class, because of having good dispersion and emulsion, washing ability, dyeing also there is certain avidity, form a kind of tensio-active agent that comprises micellar structure---dyestuff aggregate with dyestuff, increased the dissolving power of water greatly to dyestuff, and this aggregate particle is bigger, and the velocity of diffusion in solution is slower, reaches to delay the purpose of dying with resist printing.Simultaneously superpolymer PVP is introduced during loose colour cleans, fixedly hydrolised dye in solution, prevent hydrolised dye again on dye, and effectively situation is stain in improvement in vain.

Concrete prescription of the present invention is:

A. nonionogenic tenside R ₁(OR ₂) m (OR ₃) to strive content be 5-20%, wherein R for the weight hundred of nOH ₁Be H, C ₁₆-C ₁₈Alkyl, C ₉-C ₁₂Alkyl phenyl can be one or both compositions wherein; R ₂, R ₃Be ethyl or propyl group, m+n=5-25, m/n=14,

B. anion surfactant R ₄OSO ₃The weight percentage of Na is 10-25%, wherein R ₄Can be C ₁₀-C ₁₅Alkyl, or C ₉-C ₁₂Alkyl phenyl,

C. the weight percentage of polyvinylpyrrolidone (PVP-K) is 0.5-10%; The K value is 12-30,

D. the weight percentage of inorganics is 1.0-4.5%; Inorganics is one or both in yellow soda ash, sodium phosphate, the water glass.

E. surplus is a water.

Set forth most preferred embodiment of the present invention and relevant comparative example below:

The dyeing experiment:

Use reactive dyestuffs reactive red 3BS, active emerald green blue K-GL, colourity is 2%, by dyeing cotton fabric is dyeed respectively, the following program of the after washing process using that dyeed:

(1) cold wash; (2) 80 degrees centigrade of hot water wash, soap (3).(4) warm water (30-40 degree centigrade) is washed, when removal floating color is cleaned in cold wash, the add-on of loose colour clean-out system is 1g/L, temperature is 90 degrees centigrade; bath raio 1: 30, and the time is 20min, has washed the back and by GB3921-83 the fastness to washing of fabric has been measured grading; calico staining experiment is then carried out the loose colour cleaning with grey cloth and stained cloth-piece, the K/S value of grey cloth after product employing Datecolor color measurement instrument is measured and cleaned.
