The low-temperature pre-washing agent comprises the following raw materials in parts by weight: 5.0-8.0 parts of AEO-9, 4.0-7.0 parts of AEO-7, 2.0-4.0 parts of AEO-3, 2.0-4.0 parts of triethanolamine, 2.0-4.0 parts of N-methyl-2-pyrrolidone, 2.0-4.0 parts of butyl cellosolve, 1.0 part of sodium formate, 0.35 part of calcium chloride, 0.20-0.35 part of liquid protease Savinase Ultra16XLs, and the balance of ultrapure water. The low-temperature pre-washing agent disclosed by the invention has the benefits that: by adopting multiple surface active agents, the low-temperature pre-washing agent can be adaptive to various washing conditions (water quality, temperature, a water bath ratio and the like); the decontamination efficiency is high; by adopting multiple organic auxiliary agents, the decontamination time can be greatly reduced; damage and fade of cloth grass can be avoided; by adopting multiple liquid enzymic preparations, human-body organic tissue fluid, such as blood stains and excrement stains, on the cloth grass can be removed effectively at low temperature by low beating force; and the low-temperature pre-washing agent can be used for rapidly and effectively removing human-body organic tissue fluid, such as blood stains and excrement stains, at low temperature in the pre-washing stage.

Description

To do washing imperial special low temperature pre-washing agent and preparation method thereof

Technical field

The present invention relates to a kind of clean-out system, be specially the imperial special low temperature pre-washing agent of a kind of laundry, and the preparation method of this pre-washing agent; Belong to clean-out system technical field.

Background technology

Fast, low temperature, effectively to remove on cloth grass the tissue liquid such as bloodstain, just mark be washing factory always, the short slab of imperial washing process of particularly doing washing.There is following defect in tradition minimizing technology:

1, use washing liquid, emulsifying agent etc. to substitute in pre-wash stage, existing problems are the problems such as removal speed is slow, wash temperature requirement is high, removal efficiency is low, dosage of scour large (cost is high).

2, long-time soaking technology is adopted to remove on cloth grass the tissue liquid such as bloodstain, just mark, the problems such as lifetime is long, efficiency is low.

3, imperial mechanical beating power of doing washing is weak, reaches equal clean effect comparatively speaking, must rely on heavy dose of washing composition, high temperature, strong alkali environment and wash for a long time to make up.

Summary of the invention

The object of the invention is to provide a kind of laundry imperial special low temperature pre-washing agent, to solve the problems referred to above of prior art.

Another object of the present invention is to provide the preparation method of this pre-washing agent.

The object of the invention is to be achieved through the following technical solutions.

The imperial special low temperature pre-washing agent of a kind of laundry, comprises the raw material of following parts by weight:

AEO-9 5.0-8.0，

AEO-7 4.0-7.0，

AEO-3 2.0-4.0，

Trolamine 2.0-4.0,

METHYLPYRROLIDONE 2.0-4.0,

Butyl glycol ether 2.0-4.0,

Sodium formiate 1.0,

Calcium chloride 0.35,

Liquid protease Savinase Ultra16XLs 0.20-0.35,

Then balance to 100 with ultrapure water.

Described AEO is fatty alcohol-polyoxyethylene ether.

The preparation method of above-mentioned laundry dragon special low temperature pre-washing agent, the steps include:

1) first ultrapure water is all added in preparation tank, be heated to 38-42 DEG C, and drive agitator and add calcium chloride, sodium formiate successively; Stir 3-10 minute, obtain solution A;

2) AEO-9, AEO-7, AEO-3, trolamine, butyl glycol ether and METHYLPYRROLIDONE are added in solution A, stir 8-15 minute, obtain solution B;

3) successively liquid protease Savinase Ultra16XLs is joined in solution B again, continue to stir 12-20 minute, stop stirring; Obtain pre-washing agent product.

The said products is through sampling censorship; After the assay was approved, squeeze into finished cylinder, filling and package.

Step 1) in, described ultrapure water is resistivity > 10M Ω * cm (25 DEG C)

By the object of ultrapure water in aforesaid method: one is reduce the impact on protease activity, extends the shelf life; Two is reduce the formation at the imperial pre-wash stage macula lutea of washing.

The principle of the invention is as follows:

1, the selecting and stability protection of zymin: liquid protease is specifically designed to removes bloodstain, Bian Jideng human body organic tissue liquid on cloth grass at low temperatures; but its less stable in aqua environment, can extend the activity of proteolytic enzyme in aqua environment and stability after adding sodium formiate and calcium chloride.

2, the selecting of organic additive: the combination of trolamine, butyl glycol ether, pyrrolidone can accelerate the speed that washings enters fiber and dirt, can solve to improve under power washing situation patted by widget and remove bloodstain, Bian Jideng human body organic tissue liquid speed on cloth grass).

3, the selecting of tensio-active agent: have good effect to bloodstain, Bian Jideng human body organic tissue liquid on removal cloth grass.

4, weakly alkaline formula: adopt organic bases substitutional ion film alkali energy available protecting cloth grass to suffer damage, prevent cloth grass from fading.

This material employing multivariate table surface-active agent, polynary organic additive, liquid enzyme formulation etc. are composite to be formed, and be light brown clear liquid, viscosity low flow is good, and low temperature high-temperature stability is good, is applicable to very much being used in washing dragon and waits on the washing plant of employing self-feeding.

Beneficial effect of the present invention is:

1, adopt multivariate table surface-active agent can adapt to various washing operating mode (water quality, temperature, water-bath ratio etc.), detersive efficiency is high.

2, adopt polynary organic additive greatly can reduce the time of improving decontamination, and prevent the damage of cloth grass and fade.

3, adopt multi-component liquid zymin, bloodstain on cloth grass, Bian Jideng human body organic tissue liquid can be removed efficiently under low temperature, low beating power.

4, adopt this pre-washing agent can in laundry pre-wash stage fast, low temperature, effectively remove bloodstain, Bian Jideng human body organic tissue liquid on cloth grass.
