Abstract

The invention discloses a detergent for wool. The detergent comprises, in mass percent, from 5 to 30% of natural or purely natural non-ionic surface active agents, from 1 to 10% of dispersing agents, from 1 to 10% of stabilizing agents, from 0.1 to 2.0% of preservatives and the balance deionized water. As the surface active agents are natural or purely natural substances, the surface active agents are easy to be degraded. The wool cleaned by the detergent is purely white and loose, does not adhere to each other, feels good and is seldom damaged. In a washing process, wastewater in a posterior step can be recycled in a pervious step, and water consumption is low. After useful substances such as wool oil are extracted from wastewater in a second step, the wastewater can be drained directly or is used as agriculture irrigating water and does not pollute environments basically. The fat and oil content of the cleaned wool can be lower than 0.5%, and wool fiber retention rate is higher than 98%.

Description

A kind of Wool detergent

Technical field

The present invention relates to a kind of Wool detergent, can be applicable to the wool washing process of the wool course of processing, belong to the washing composition technical field.

Background technology

Along with the development of woolen industry, both at home and abroad the woolen demand is increased year by year.Wool before the processing contains more impurity, must remove in the scouring of wool stage, to obtain the required wool fiber of subsequent handling.Wool impurity is different with sheep variety and region, and difference is also very big.The main impurity that common wool contains can be divided into three kinds: oiliness impurity (yolk), water-based impurity (suint), water-insoluble impurity (inorganics in the earth, physiology movement and Mierocrystalline cellulose etc.).Wool washing process is intended to remove above-mentioned impurity; Wool detergent plays an important role in this process; The quality of its performance will directly influence washing back woolen staple length, whiteness, shatter value, and woolen spinning property and feel have very big influence to woolen following process and quality.

Common Wool detergent mainly contains three types at present.The first kind is adopted by domestic most small processing factory; Such washing composition be contain alkyl sodium sulfonate, sodium alkyl benzene sulfonate, to the versatility washing composition of tensio-active agents such as methoxyl group fat amido sodium sulfonate; Like washing powder, liquid detergent etc., its shortcoming is: one, clean scarce capacity, the wool yolk content after the washing is still a lot; Influence follow-up manufacturing procedure, and might influence the quality of the finished product.If two carry out the secondary repeated washing with common concentration, wool-cleaning technology is complicated, the scouring of wool cost raises, and damage also can strengthen to woolen.Three, in order to remedy the deficiency of cleansing power, increase washing effect, often add ionogen such as sodium sulfate, sodium-chlor, Sodium hexametaphosphate 99, making wool washing sewage, mud is high salinity property, and the processing costs of pollutent is very high.Second type is the tailored version Wool detergent that some famous enterprises adopted; Hydrapol TN450 hair detergent like Australian Huntsman Corporation (Huntsman Corporation Australia Pty Limited) product; Washing effect is better; But price is more expensive, and component formula is not open yet.The 3rd type is some public technology washing composition; Like the patent No. is the Chinese invention patent " Wool detergent " (Granted publication number for CN1033462C) of ZL91105763.3; This patent component and weight proportion are: polyoxyethylene nonylphenol 10～25%, thiocarbamide 1～8%, ammonium sulfate 2～10%; Urea 3～12%, surplus are water.Polyoxyethylene nonylphenol belongs to the APEO category, and many experimental datas show that the APEO biological degradation is slow, and the catabolism thing also has potential hazard property to environment, so some countries formulate this series products of rules forbidding.And for example the patent No. is the Chinese invention patent " detergent for animal hair " (Granted publication number for CN10525561B) of ZL200910029574.0; Application number is open " Wool detergent " (application publication number is CN101921662A) of Chinese invention patent application of 200910032329.5; Application number is that all to mention with the AEO in several kinds of washing composition technology such as open " raw wool hair detergent " (application publication number is CN102041187A) of 201010619527.4 Chinese invention patent application be tensio-active agent, adds other again and becomes the assignment system Wool detergent.Above-mentioned washing composition or because of unfriendly to environment, or not good enough because of washing wool effect, all be not used on a large scale.

Summary of the invention

The objective of the invention is to the shortcoming that exists in the prior art, good, the easy degraded of a kind of washing effect, environment amenable Wool detergent are provided.

The object of the invention is realized like this:

Selecting easy one or more natural sources or pure natural nonionogenic tenside of degrading, having good clearing power, detersive power is the main body of washing composition; Select for use again and make wool impurity good dispersion agent of dispersion effect in water; Add the stablizer that improves the washing composition storage stability; Add the minor amounts of non-toxic sanitas, it is formulated to be equipped with deionized water.Natural nonionogenic tenside can be selected tea saponin, sapindoside etc. for use, and the natural source nonionogenic tenside can be selected APG, sorbitan esters etc. for use; It is 2～8 fattiness alcohol that dispersion agent can be selected carbonatoms for use; Stablizer can be selected the bigger ammonium salt of solubleness for use, like ammonium sulfate, ammonium chloride, primary ammonium phosphate etc.; Sanitas can be selected sorbate, nipagin esters, Sodium Benzoate etc. for use.

Each component quality proportioning is following:

Nonionogenic tenside 5～30%

Dispersion agent 1～10%

Stablizer 1～10%

Sanitas 0.1～2.0%

The deionized water surplus

As preferably, each component quality proportioning is following:

Nonionogenic tenside 10～25%

Dispersion agent 1～8%

Stablizer 1～5%

Sanitas 0.3～1.5%

The deionized water surplus

As the best, each component quality proportioning is following:

Nonionogenic tenside 12～20%

Dispersion agent 2～8%

Stablizer 2～5%

Sanitas 0.3～1.5%
