In order to solve the above problems, a first aspect of the present invention provides a detergent for textile, which is prepared from the following raw materials: biological enzymes and surfactants; the biological enzyme is at least one selected from alkaline protease, pectinase, amylase, lipase and cellulase.
In some preferred embodiments, the biological enzymes are cellulases and lipases.
Cellulase, YGCellRdfined PW400 (activity 400, 000U/g), purchased from Weifang Yiguang Biotech Ltd; lipase, purchased from Zhonghe Zhongli Bio products, Inc.
In some preferred embodiments, the cellulase and lipase are present in a weight ratio of (1-5): 0.5.
in some preferred embodiments, the cellulase and lipase are present in a weight ratio of 1.5: 0.5.
in the experimental process, the applicant is researched and obtained through a large number of creative experiments, the cleaning and stain removal effects of the textile detergent can be greatly improved through the interaction between the cellulase and the lipase in the system, and particularly, the weight ratio of the cellulase to the lipase is 1.5: 0.5, the best stain removal is achieved while still ensuring improved storage stability of the resulting cleaner, and the applicant speculates that this may be due to: in the system, due to the existence of the raw materials such as the surfactant, the thickening agent and the like, a stable environment is provided for the existence of the cellulase and the lipase, when the prepared detergent acts on the surface of the fabric, particularly a pure cotton fabric, the cellulase acts on an amorphous area of cellulose fibers through glucolase to decompose cellulose macromolecules into a polysaccharide small chain segment structure, so that the fluffy feeling of the fabric is enhanced, meanwhile, the contact probability is provided for the lipase and stains or oil stains existing in the amorphous area of a fiber layer, and the stains, the oil stains and even stubborn stains on the collar of a jacket prepared from the cotton fabric which are difficult to remove are removed, so that the effect of quickly removing the stains and the oil stains is achieved.
However, in this system the applicants have also found that when cellulase and lipase are added in a weight ratio of 1: 1, the stain removing effect on the neck of clothes made of cotton fabrics was affected, and the applicants speculated that the stain removing effect on the neck of clothes made of cotton fabrics was affected because the cellulase was used to hydrolyze cellulose in an excessive amount at the initial stage of the reaction and the synergistic effect was reduced at the later stage in cooperation with the lipase.
In some preferred embodiments, the surfactant is selected from at least one of an anionic surfactant, a cationic surfactant, a nonionic surfactant, and an amphoteric surfactant.
In some preferred embodiments, the surfactant is selected from the group consisting of amphoteric surfactants and anionic surfactants.
In some preferred embodiments, the anionic surfactant is selected from at least one of sodium linear alkylbenzene sulfonate, sodium alpha-olefin sulfonate, sodium laureth sulfate, sodium tetradecanol polyoxyethylene ether sulfate, and sodium fatty acid methyl ester sulfonate.
In some preferred embodiments, the anionic surfactant is sodium laureth sulfate.
In some preferred embodiments, the amphoteric surfactant is selected from at least one of cocamidopropyl betaine, cocoamphocarboxyglycinate, isostearyl amphoalanate, cocoamphoglycinate, laurylalanine diethanolamide salt.
In some preferred embodiments, the amphoteric surfactant is cocamidopropyl betaine; the content of free amine in the cocamidopropyl betaine is less than or equal to 2 percent.
In some preferred embodiments, the weight ratio of amphoteric surfactant to anionic surfactant is 1: (0.5-3.5).
In some preferred embodiments, the weight ratio of cocamidopropyl betaine to sodium laureth sulfate is 1: (0.5-3.5).
In some preferred embodiments, the weight ratio of cocamidopropyl betaine to sodium laureth sulfate is 1: 2.8.
in the experimental process, the applicant finds that different types of surfactants are selected for compounding, and particularly, the surfactant cocoamidopropyl betaine amphoteric surfactant and the anionic surfactant sodium laureth sulfate are compounded and used, wherein the weight ratio of the surfactant cocoamidopropyl betaine to the anionic surfactant sodium laureth sulfate is 1: (0.5-3.5), in particular in the range of 1: 2.8, the detergent has better decontamination effect on cotton fabrics, can ensure better foaming performance of the prepared detergent, and is presumed by the applicant as the reason: in the system, the cocoamidopropyl betaine and the sodium laureth sulfate can provide more active groups for the system, so that the strong interaction between positive charges and negative charges is enhanced, and the nonpolar hydrocarbon chain in the system has certain hydrophobic interaction, so that the surfactant in the system is arranged more compactly at a liquid/gas interface; meanwhile, the weight ratio of the cocamidopropyl betaine to the sodium laureth sulfate is 1: 2.8, the water phase can be promoted to combine to form mixed micelles, and after the mixed micelles are formed, the movement frequency between free groups is reduced, so that the oriented water molecules around the hydrophilic groups of the surfactant are reduced, the free water molecules are increased, and the prepared detergent has better foaming performance.
In some preferred embodiments, the weight ratio of the biological enzyme to the surfactant is 1: (2-6).
In some preferred embodiments, the weight ratio of the biological enzyme to the surfactant is 1: 4.5.
in the experimental process, the applicant finds that the stain removal capability of cotton fabrics, especially the stain removal capability of poplin fabrics, can be greatly improved by compounding the biological enzyme and the surfactant. The reasons for this may be: under the condition that surface activity exists, more hydrophilic and hydrophilic groups can be provided for the system, the existence of the hydrophilic and lipophilic groups can form further complexation with active substances in the biological enzyme, and the combination of the hydrophilic groups and the hydrophilic groups with stains in the textile can be enhanced while the biological enzyme permeates into the textile, so that the aim of deeply removing the stains is fulfilled; however, because the poplin has different density in the warp and weft directions, dead corners may remain in the common detergent during cleaning; however, the detergent prepared by the invention can enhance the fluffy feeling of textiles when in use, can enhance the immersion capability of the surfactant in different density directions, and further enhances the cleaning and dirt removing capabilities.
In some preferred embodiments, the preparation raw materials further comprise at least one of a thickener, a preservative, a perfume, a whitening agent, and a solvent.
In some preferred embodiments, the preparation raw materials further comprise a thickener and a solvent.
In some preferred embodiments, the thickener is sodium chloride.
In some preferred embodiments, the weight of sodium chloride is 2 to 20 wt% of the weight of the surfactant.
In the experimental process, the applicant finds that the sodium chloride is added into the system, and the weight of the sodium chloride is ensured to be 2-20 wt% of the weight of the surfactant, so that the service life of the detergent can be prolonged, the detergent can be ensured to be easily washed off in the washing process, and the waste of a large amount of water is avoided. The reasons for this may be: in the system, an active layer can be formed at an oil-water interface due to the existence of the surfactant and the biological enzyme, stains are surrounded by a large amount of foams in the cleaning process, so that the stains are separated from textiles and rise to the liquid level, at the moment, the mutual attraction among water molecules on the water surface and the attraction between the water molecules and the air are weakened due to the existence of sodium chloride, the surface tension of the foams at the water-air layer is changed, and the foams are further guaranteed to be broken in the cleaning process.
In some preferred embodiments, the solvent is water.
In some preferred embodiments, the preparation raw materials further comprise a perfume.
In some preferred embodiments, the preparation raw materials comprise, in weight percent: 30-50% of surfactant, 5-12% of biological enzyme, 0.1-2% of thickening agent, 0.1-0.5% of essence and the balance of water to 100%.
The second aspect of the invention provides a preparation method of a textile detergent, which comprises the following steps:
1) mixing the preparation raw materials, heating to 50-60 ℃, and stirring until the raw materials are completely dissolved;
2) and then cooling to room temperature to obtain the product.
The present invention will be specifically described below by way of examples. It should be noted that the following examples are only for illustrating the present invention and should not be construed as limiting the scope of the present invention, and that the insubstantial modifications and adaptations of the present invention by those skilled in the art based on the above disclosure are still within the scope of the present invention.
