Embodiment 1

[0037] A kind of manufacture method of the natural dirt dirt cloth of checking protease application effect, comprises the following steps:

[0038] A. Pre-treatment of pad stained cloth: standard cotton interlining is used for pad stained cloth, and the treatment method is as follows:

[0039] Wash the standard cotton interlining with hot water at 35°C~45°C for 30min~50min, rinse with water after washing, iron at low temperature and dry before use;

[0040] B. Padding of stained cloth: Dip the standard cotton interlining treated in step A into the prepared natural stain solution, lift the two corners of the standard cotton interlining, and stick it on the roller of the rolling pad dyeing machine, after the pad dyeing is completed The standard cotton interlining cloth was dried at room temperature to complete the natural soil stain cloth for testing the effect of protease application.

[0041] Further, the pad dyeing condition of the pad dyeing machine in step B is:

[0042] ...

Embodiment 2

[0061] The present embodiment is an optimization scheme based on Example 1, and a method for making a blood-stained dirt cloth is provided, and the method for making comprises the following steps:

[0062] Take a container and add anticoagulant 2% EDTA-2Na aqueous solution to it first, then quickly pour the collected fresh chicken blood into the container and mix quickly, and finally make up the weight with distilled water, and store it in the refrigerator for later use. Use the first 200 mesh filter cloth to filter to get the blood-stained dirt impregnating solution, and carry out pad-dyeing of the stained cloth. Immerse the treated standard cotton interlining in the blood-stained and dirt-impregnating solution, lift the two corners of the standard cotton interlining with tweezers, and stick it on the rolling pad-dyeing On the machine roller, after the tie-dyeing is completed, the standard cotton interlining is dried at room temperature to obtain the blood-stained dirt cloth. ...

Embodiment 3

[0070] The present embodiment is an optimization scheme on the basis of Example 1, and provides a kind of preparation method of cooked gravy dirt dirt cloth, and described preparation method comprises the following steps:

[0071]Dissolve braised gravy, vegetable oil, glyceryl monostearate, and soy sauce in a water bath, filter through a 200-mesh filter cloth, and emulsify in a homogeneous emulsifier at a speed of 2500-3500r / min in a water bath at 40-50°C for 10 minutes to obtain Cooked gravy dirt impregnation solution, carry out pad dyeing of stained cloth, immerse the treated standard cotton interlining in the cooked gravy dirt impregnation solution, use tweezers to lift the two corners of the standard cotton interlining, stick it on the roller of the rolling pad dyeing machine, tie-dye After completion, the standard cotton interlining is dried at room temperature to obtain the gravy stained cloth.

[0072] Described braised gravy, the weight fraction of vegetable oil, glyce...

Abstract

The present invention discloses a natural dirt stain cloth for inspecting protease application effect, and a production method thereof, wherein the natural dirt stain cloth comprises a blood stain dirt stain cloth, a cooked meat juice dirt stain cloth, and a milk powder dirt stain cloth. The production method comprises: pretreatment of a pad dyeing stain cloth, and pad dyeing of the stain cloth. According to the present invention, with the production method, the cloth is subjected to pad dyeing with the protein-based natural dirt generally produced in the life by controlling a certain pad dyeing condition, such that the pad dyeing stain cloth can be quantitative and uniform, and the accuracy and the uniformity are accurate compared to the stain cloth obtained through the drop dyeing method.

Description

technical field [0001] The invention belongs to the field of cleaning agent standards, in particular to a natural dirt cloth for testing the application effect of protease and a preparation method thereof. Background technique [0002] Enzyme application technology is currently widely used in foreign detergent products. Although it started relatively late in China, it has developed rapidly in recent years, and enzyme application technology has become very mature. However, the evaluation of the application effect of enzyme preparations is currently only the national industry standard - standard stained cloth JB-01 / JB-02 / JB-03. In real life, some natural dirt is often encountered, and the production method of natural dirt and dirt cloth is currently dripping dirt on white cotton cloth by artificial dripping method, and doing a washing test after placing it for 24 hours to evaluate the application effect. The uniformity of the dirt prepared by the existing artificial drip dyei...
