Description

Antibacterial type linen detergent Technical Field The invention relates to the technical field of daily chemicals, in particular to an antibacterial linen detergent. Background In public places such as hotels and hospitals, the health condition of the linen is directly related to public health. Conventional linen detergents are mainly focused on removing stains and oil stains, and their bactericidal capacity is mostly dependent on high temperature washing or post-addition of chlorine-containing bleaching agents (e.g. sodium hypochlorite). However, the high-temperature washing has huge energy consumption and damages to a plurality of fabric fibers, while chlorine-containing bleaching agents have strong bactericidal activity, but are easy to fade and embrittle fabrics, and residual chlorine can irritate skin and react with organic matters to generate harmful byproducts, so that the environment is not friendly. Detergents incorporating a single antimicrobial agent (e.g., triclosan, certain quaternary ammonium salts) have also been presented in the prior art. However, these antimicrobial agents have problems in that (1) microbial resistance is easily generated, the antimicrobial effect is reduced after long-term use, (2) the antimicrobial spectrum may be insufficient, the effect on certain fungi or viruses is limited, (3) part of the conventional antimicrobial agents are poor in biodegradability and have an environmental accumulation risk, and (4) the antimicrobial efficacy may be disturbed or masked in an organic dirt environment where washing is complicated. Therefore, developing a special linen detergent which can exert excellent efficacy at conventional washing temperatures (such as 40-60 ℃), integrates efficient decontamination, broad-spectrum durable antibiosis, low corrosion and environmental friendliness, and is a technical problem to be solved in the field. Disclosure of Invention The invention aims to solve the technical problem of overcoming the defects of the prior art and providing an antibacterial linen detergent. The detergent realizes one-time washing and simultaneously completes deep cleaning and efficient sterilization under the premise of not depending on high temperature and Jiang Lv bleaching through the synergistic effect of a unique composite antibacterial system and biological enzyme, has lasting antibacterial effect, and is small in damage to linen and environment-friendly. The invention provides a technical scheme that an antibacterial linen detergent comprises the following components in percentage by weight: 20% -40% of a surfactant system; 3-10% of a composite antibacterial system; 2% -8% of a compound biological enzyme preparation; 15-30% of a builder and an alkaline agent; 1% -5% of chelating agent; 0.5% -2% of corrosion inhibitor; A proper amount of pH regulator for regulating the pH value of the final product to 9.5-11.0; deionized water for the rest; wherein, the composite antibacterial system consists of the following components: a) A double-stranded quaternary ammonium salt compound; b) Guanidine polymers; c) Plant source antibacterial synergist.
