Problems solved by technology

These methods are difficult for ordinary consumers to use in daily life, for example: reagents are not easy to obtain and some reagents have safety risks; Color development under acidic (Coomassie brilliant blue) conditions, longer color development time, etc.
Moreover, these methods all need to disperse the substance to be detected in the solution, and some also need to be heated
In summary, the existing industrial methods for identifying proteins suffer from the aforementioned deficiencies that make them unsuitable for commercial use in testing the presence of protein residues on fabrics

Abstract

The invention discloses a method for quickly detecting a protein residue on a fabric. The method for quickly detecting the protein residue on the fabric comprises the steps of (1) preparing an aqueous solution containing pigment molecules or a suspension solution containing colored particles; (2) immersing the fabric with the protein residue into the aqueous solution or the suspension solution prepared in the step (1) and enabling the protein to be absorbed by the pigment molecules or the colored particles, wherein the time for immersing lasts for 1 second-20 minutes. Due to the adoption of the principle that an absorption property of a fabric part with the residue protein and absorption properties of other parts of the fabric on the pigment molecules or the colored particles, reasonable process and immersion time are controlled, so that quick detection of protein residues on the fabric is realized; a color development reagent used in the method is common and easily-available and has no harm to the human body; the method is simple and convenient to operate, high in color-developing speed and capable of easily developing colors and easily judging through naked eyes.

Description

Technical field [0001] The invention belongs to the field of fabric cleaning, and particularly relates to a method for quickly inspecting protein residues on fabrics. Background technique [0002] With the development of society and the improvement of people's living standards, people will encounter various stains on their clothes. Among various stains, such as milk stains, saliva stains, sweat stains and other protein stains are colorless or white due to their appearance. It is difficult to distinguish with the naked eye after being stained on the fabric; but if these stains cannot be cleaned, the protein remaining on the fabric will gradually age and turn yellow or breed bacteria, which will adversely affect the appearance of clothes and the health of consumers. Therefore, people continue to improve the performance of detergents for these special stains, in order to remove these stains more effectively. However, since these stains cannot be distinguished by the naked eye wheth...
