Problems solved by technology

In addition, the specific reaction environment in the liquid detergent system may still inactivate the enzyme, which is extremely detrimental to the quality stability and reliability of enzyme-infused washing products, and will also lead to the loss of enzyme-infused washing products after transportation and storage. The cleaning power of the articles is greatly weakened during the washing process, etc.
[0003] Patent CN109135960A provides the use of a polymer as a protease stabilizer in detergents and a detergent composition. Ethoxylated polyethyleneimine is used as a protease stabilizer in detergents, but its cleaning power fails to meet Market demand

Embodiment 1

[0099] A kind of detergent, by the mass fraction is the protease pellet of 0.6%, the polyethylene glycol that the mass fraction is 5.75%, the citric acid that the mass fraction is 1.4%, the magnesium salt that the mass fraction is 1.5%, the mass fraction is 2% EDTA disodium salt, essence with a mass fraction of 0.15%, viscosity regulator with a mass fraction of 1.85%, sodium alkylsulfonate with a mass fraction of 6%, surfactant with a mass fraction of 12%, The balance is obtained after mixing with water.

[0100] The magnesium salt is a mixture composed of magnesium ascorbyl phosphate, magnesium salicylate and magnesium gluconate in a mass ratio of 7.2:5.8:11.2.

[0101] The essence is rosemary oil, acetyl triethyl citrate, α-ring citral, eucalyptus oil, marjoram essential oil, sour cedrol ester, irone in a mass ratio of 6.5:2.3:4.1:6.3:9.8:4.6: 2.2 Composition of the mixture.

[0102] The viscosity modifier is a mixture composed of polyvinylpyrrolidone, sodium carboxymethyl...

Embodiment 2

[0121] It is basically the same as Example 1, the only difference is:

[0122] The preparation method of described modified chitosan is:

[0123] R1 mixed chitosan and 4.3% acetic acid aqueous solution at 35° C. and stirred at a speed of 500 rpm for 40 min to obtain a solution D with a mass fraction of chitosan of 18%;

[0124] R2 mixed the solution D and 8% lactic acid aqueous solution at a mass ratio of 5:3 at 15°C and stirred at a speed of 400 rpm for 30 min to obtain a solution E;

[0125] R3 Mix the modifier and the solution E at 5°C with a mass ratio of 3:95 and stir at a speed of 500rpm for 25min, then irradiate with ultraviolet rays with a wavelength of 140nm and a power of 100W for 1h, filter and dry the precipitate at 67°C 10h, to obtain the modified chitosan.

[0126] The modifier is methyl 2-(methylthio)propionate.

Embodiment 3

[0128] It is basically the same as Example 1, the only difference is:

[0129] The preparation method of described modified chitosan is:

[0130] R1 mixed chitosan and 4.3% acetic acid aqueous solution at 35° C. and stirred at a speed of 500 rpm for 40 min to obtain a solution D with a mass fraction of chitosan of 18%;

[0131] R2 mixed the solution D and 8% lactic acid aqueous solution at a mass ratio of 5:3 at 15°C and stirred at a speed of 400 rpm for 30 min to obtain a solution E;

[0132] R3 Mix the modifier and the solution E at 5°C with a mass ratio of 3:95 and stir at a speed of 500rpm for 25min, then irradiate with ultraviolet rays with a wavelength of 140nm and a power of 100W for 1h, filter and dry the precipitate at 67°C 10h, to obtain the modified chitosan.

[0133] The modifier is ditridecanyl thiodipropionate.

Abstract

The invention discloses a detergent and a towel washing process. The detergent is obtained by mixing protease beads, polyethylene glycol, citric acid, a magnesium salt, ethylenediamine tetraacetic acid disodium salt, essence, a viscosity modifier, alkyl sodium sulfonate, a surfactant and water. The towel washing process comprises four steps of washing, rinsing, dewatering and airing. The detergent provided by the invention has strong cleaning power.

Description

technical field [0001] The invention relates to the technical field of towel washing, in particular to a detergent and a towel washing process. Background technique [0002] Adding an appropriate amount of enzymes with good biological activity to detergent products has been widely used in various details in the detergent industry for decades. The enzymes used include but are not limited to protease, lipase, Cellulase and its derivative complexes. Nowadays, proteases have the most economic value and good profit properties in commercial applications, and related practitioners are increasingly favoring protein engineering to improve the various proteases and their properties that originally naturally existed in the natural environment. variants or derivatives. Among them, many commercial proteases have made great progress in terms of enhanced activity, enhanced stability, or enhanced solubility, which greatly meet the increasingly complex needs of the market and consumers.
