Embodiment 1

[0026] The preparation of hydrolyzed wheat protein: gluten is mixed with the aqueous solution of 4% gluten by weight percentage concentration, and regulating temperature is 60 ℃ and pH value are 8.5, then adding and accounting for gluten weight is 1% alkaline The protease was hydrolyzed for 210 minutes, the temperature was raised to 95° C. to inactivate the enzyme for 15 minutes, and the supernatant was obtained by centrifugation at 4000 r / min for 20 minutes. The supernatant was freeze-dried to obtain hydrolyzed wheat protein.

[0027] Preparation of silicone polymer: Dissolve dimethyldiallylammonium chloride and γ-methacryloxypropyltris(trimethylsiloxy)silane in a weight ratio of 1:3 in N,N - In dimethylformamide, the temperature was raised to 65° C. under an inert atmosphere, the N,N-dimethylformamide solution of azobisisobutyronitrile was added dropwise and kept for 10 hours to react to obtain the organosilicon polymer; The amount of azobisisobutyronitrile used is 2% by wei...

Embodiment 2

[0031] The preparation of hydrolyzed wheat protein: gluten is mixed with the aqueous solution of the gluten of 5% by weight percent concentration, and regulating temperature is 60 ℃ and pH value are 8.5, then add and account for gluten weight and be 2% alkaline The protease was hydrolyzed for 165 minutes, the temperature was raised to 95° C. to inactivate the enzyme for 15 minutes, and the supernatant was obtained by centrifugation at 4000 r / min for 20 minutes. The supernatant was freeze-dried to obtain hydrolyzed wheat protein.

[0032] Preparation of silicone polymer: Dissolve dimethyldiallylammonium chloride and γ-methacryloxypropyltris(trimethylsiloxy)silane at a weight ratio of 1:4 in N,N - In dimethylformamide, the temperature was raised to 63°C under an inert atmosphere, a N,N-dimethylformamide solution of azobisisobutyronitrile was added dropwise and kept for 11 hours to react to obtain an organosilicon polymer; The amount of azobisisobutyronitrile used is 2.5% by weig...

Embodiment 3

[0036] The preparation of hydrolyzed wheat protein: gluten is mixed with the aqueous solution of the gluten of 3% by weight percentage concentration, and regulating temperature is 60 ℃ and pH value are 8.5, then adding and accounting for the weight of gluten is 3% alkaline The protease was hydrolyzed for 120 minutes, the temperature was raised to 95° C. to inactivate the enzyme for 15 minutes, and the supernatant was obtained by centrifugation at 4000 r / min for 20 minutes. The supernatant was freeze-dried to obtain hydrolyzed wheat protein.

[0037]Preparation of silicone polymer: Dimethyldiallylammonium chloride and γ-methacryloxypropyltris(trimethylsiloxy)silane in a weight ratio of 1:5 were dissolved in an organic solvent , under an inert atmosphere, the temperature was raised to 67°C, the organic solvent solution of the initiator was added dropwise and kept for 9 hours, and the organic silicon polymer was purified; the amount of the initiator was γ-methacryloyloxypropyl tri...

Abstract

The invention relates to a color protection and brushing-free laundry detergent, which is prepared from the following raw materials of iso-tridecanol polyoxyethylene ether, polyethenoxy ether of lauryl alcohol, carbon octyl glycoside, triethanolamine, polyethylene glycol monooleate, tetrasodium glutamate diacetate, alpha-sodium glucoheptonate, hydrolyzed wheat protein, organic silicon copolymers,sodium polyacrylate, dimethylamine and epoxy chloropropane polymers, citric acid monohydrate, essence, phenoxyethanol and deionized water. The invention also provides a preparation method of the colorprotection and brushing-free laundry detergent. The color protection and brushing-free laundry detergent provided by the invention has efficient detersive power; the brushing-free effect is achieved;the occurrence of damage condition of clothes fabrics due to mechanical stirring can be avoided. The color protection and brushing-free laundry detergent also has the color protection and brighteningeffects; easy-to-fade clothes can be effectively cleaned; the occurrence of washing accidents can be avoided; after the washing, clothes are clean and bright.

Description

technical field [0001] The present invention relates to a kind of laundry liquid, more specifically, it relates to a kind of color-protecting brush-free laundry liquid and its preparation method. Background technique [0002] In recent years, washing brightly colored clothes with traditional laundry detergent will cause color fading, color crossing and fading, and it takes a long time to remove stains during the washing process, so it will cause different degrees of damage to the fabric in many ways , especially not suitable for washing high-grade fabrics. In order to make the washing fast, the clothes of different fabrics can be used, and the clothes will not cause color fading, color crossing and fading during the washing process. Contents of the invention [0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a color-protecting brush-free laundry detergent, which not only has high detergency, but also can avoid brushing...
