Description

Cleaning agent for fibre fabric

The present invention relates to washing composition, relate in particular to tensio-active agent or organic solvent.

As everyone knows, wool, the rabbit hair are the main raw materials of wool textile.Wool textile, with clean hair through comb, spin, knit, series of process such as dyeing and finishing processes, dyeing and finishing is one of main technique of assurance quality product.Before dyeing and finishing, spinning product must pass through braying, slubbing product and then need handle through fulling, to eliminate the ash bits that stay with crude oil, static inhibitor and when singing that in spinning, weaving process, add, dust etc., avoid because of greasy dirt and defective such as the existence of insoluble soa salt causes uneven dyeing, Dry Sack is dark and gloomy, feel is greasy or plate is hard.In addition, another free-revving engine that braying and fulling are handled is that the fat content in the wool is dropped to 0.6% and 0.8% respectively from 4～5%, so that wool textile has best flexibility, elasticity, intensity and work-ing life, and guarantees to make to contain the soap rate less than 1%.

At present, China's wool textile industry is used for the washing composition of braying and fulling, is the washing composition that belongs to anionic, cationic, amphoteric and nonionic surface active agent respectively.What wherein, use was the widest is soap, Sodium dodecylbenzene sulfonate, washing composition LS, 209 washing composition, Lamepon A, detergent JU, peregal etc.Undoubtedly, above-mentioned washing composition has gratifying effect really for the outer greasy dirt that dyes on the fabric.But it is but almost powerless to include fat for woolen, can only reduce to 1.2～1.4% to fat content with 4～5%, does not reach the fat content 0.6% and 0.8% of international standard regulation far away.So some outlet woolen knitwear has to use the braying of import washing composition, fulling.

The present invention aims to provide a kind of purificant that is used for braying, fulling, the approaching neutrality of its pH value, soap value are less than 1%, and have performances such as good wetting, infiltration, emulsification, diffusion, foaming, can not only remove the outer greasy dirt that dyes of wool fabric, and can be reduced to standard value 0.6%～0.8% to fat content in the wool, to satisfy the needs of woolen industry.

The present invention realizes above-mentioned purpose like this:

Outer pollution mainly is burnt hair in view of woolen, dust, grease that composition is different and static inhibitor, diluting water during because of washing has the hardness difference again, so be necessary to select can not form insoluble calcium soap or magnesium soap, and have wetting, emulsification, aniorfic surfactant sodium laurylsulfonate that the detersive power that lathering property is good is stronger or Sodium dodecylbenzene sulfonate or Dodecyl Mercaptan sodium or its mixture and ionogenic surfactant OP-10 or peregal or its mixture, so that by the greasy dirt emulsification of being washed, be dispersed in the washing composition and by diffusion and adsorb by foam, take away; Add an amount of phosphoric acid or phosphoric acid salt, to strengthen washing effect; Add sodium carbonate solution,, make washing composition near neutral (so as if being the washing synergistic agent with phosphoric acid salt, then the yellow soda ash add-on is cut down according to the circumstance) with neutralising phosphoric acid.Because above composition can only be removed and outer dye greasy dirt, still can not make wool include liposoluble and go out and make fat content stably reduce to 0.6～0.8%, so be necessary to add different organic solvent, solubility promoter and the permeate agents of polarity power degree; 2,4 diacetylmethanes, isopropenyl acetate, benzene or toluene or dimethylbenzene, acetone, ethanol, 200# solvent oil, trolamine, so that purificant has better wetting infiltration, diffusibility, make the woolen swelling by it, strengthen it to including the liposoluble output capacity, thereby reduce to through the woolen fat content behind the fulling 0.8% or braying after the woolen knitwear fat content reduce to 0.6%, good in order to guarantee feel, it is residual not have insoluble magnesium soap or calcium soap, so must guarantee that the soap value of this purificant is less than 1%.

Purificant of the present invention is by aniorfic surfactant sodium laurylsulfonate or Sodium dodecylbenzene sulfonate or Dodecyl Mercaptan sodium or its mixture, nonionic surface active agent OP-10 or peregal or its mixture, washing synergistic agent phosphoric acid or phosphoric acid salt, neutralization (pH value adjustings) agent yellow soda ash or sodium bicarbonate aqueous solution, as the different propylene fat of 2,4 diacetylmethanes, permeate agent acetic acid of solvent and permeate agent, the trolamine of making permeate agent and neutralizing agent, the 200# solvent oil of making solvent and benzene (or toluene or dimethylbenzene), solubility promoter acetone and ethanol composition; Wherein infiltration, solvent and the solubility promoter total content in purificant should be not less than 18%.

For the soap value that guarantees purificant less than 1%, solid part is about 34%.Purificant to the woolen rate of permeation about 33%, pH value between 4～8, the fat content of Mao Dihou woolens reaches 0.6～0.8%, through above-mentioned purificant component content being changed and testing, determine that prescription (water is contained in the aqueous solution, and the various materials of not doing in addition to calculate, add are in volume percent) is as follows:

The aqueous solution of sodium laurylsulfonate or Sodium dodecylbenzene sulfonate or Dodecyl Mercaptan sodium or its mixture (concentration is in 30%) 53～56%

OP-10 or peregal or its mixture (commercially available) 5.2～5.9%

Phosphoric acid (d=1.17) 1.3～1.5%

Aqueous sodium carbonate (20%) 12～17%

Trolamine 5.1～5.9%

2,4 diacetylmethanes 2.6～2.9%

Isopropenyl acetate 5.2～5.8%

Benzene or toluene or dimethylbenzene 4.0～5.0%

Acetone 1.0～1.6%

Ethanol 2.7～3.2%

200# solvent oil 2.7～3.2%

If the washing synergistic agent is a phosphoric acid salt, then neutralizing agent yellow soda ash or sodium bicarbonate aqueous solution can add as one sees fit less, and the pH value of purificant is transferred to neutral getting final product.

Implement and effect:

Example 1: I prepared for the first time in purificant organic solvent, hydrotropy and permeate agent total content be 16% purificant, for woollen milol be used for fulling, the woolen knitwear fat content has dropped to 1.5% from 4.6%, be used for braying woolen knitwear fat content and dropped to 1.2% from 4.5%, prove that the effect of this purificant is better than the various commercially available agent of washing.

Example 2: from woollen milol's feedack, adjusted the ratio (being above-mentioned prescription) of each component of purificant, the sample of testing oneself: pH value is 7.2, solid part is 35%, contain soap rate (1%; The rate of permeation that woollen milol measures is 33%.Be used for braying, wash the spinning product in back and dye greasy dirt outward and eliminated, the woolen knitwear fat content drops to 0.6% by 4.5; Be used for fulling, oil removal is good, and the woolen knitwear fat content has dropped to 0.8% from 4.6%.The international standard that meets the woolen knitwear fat content fully.After washing back woolen knitwear dyeing and finishing, have color and luster just, bright and clean, the sponginess of fabric and high resilience.

Example 3: hear the news and asked for a sample afterwards in the hotel, is used for washing woollen blanket and carpet, and feedback information is: the once used washing composition of scrubbing force rate is all strong, and it is the same even also much better with new the time to wash back fabric feel.

The development of this purificant and use proof, its braying, fulling effect are highly desirable, have solved in China's woolens industry braying and the fulling washing composition problem that end for a long time solves, and provide basic substance for improving China's woolen knitwear class, have satisfactorily realized the present invention's purpose.
