Abstract

The invention discloses a preparation method of a composite antibacterial softening agent, and belongs to the technical field of the preparation of an antibacterial finishing agent used for a textile fabric. The preparation method comprises the following steps of: preparing a mixed emulsion: mixing an acrylic emulsion, an emulsifier and a solubilizer in deionized water, stirring uniformly, raising a temperature, adding low-yellowing amino silicon oil at a high speed to stir, then adding the deionized water to continue stirring at the high speed, and obtaining the mixed emulsion; and preparing the finished product composite antibacterial softening agent: adding antibacterial components in the mixed emulsion, rapidly stirring the mixed emulsion at a room temperature and a normal pressure, and preparing the composite antibacterial softening agent. The preparation method has the advantages of reasonable selected raw materials and simple preparation method and technology steps; harsh equipment and complicated operating instruction are not needed; and the antibacterial ratios of the obtained composite antibacterial softening agent to staphylococcus aureus and escherichia coli can reach more than 99% and 99.2% respectively.

Description

technical field [0001] The invention belongs to the technical field of preparation of antibacterial finishing agents for textile fabrics, and in particular relates to a preparation method of a composite antibacterial softener. Background technique [0002] In recent years, due to the gradual improvement of people's living standards, people's requirements for clothing closely related to daily life are also getting higher and higher, and people's clothing is developing towards functional aspects. In order to improve the feel and comfort of clothing, hydrophilic amino silicone oil is usually used as a finishing agent for fabrics after being emulsified with water. This finishing agent can endow fabrics with better softness, slipperiness and hydrophilicity. For example, Chinese Patent Publication No. CN1546553A relates to non-yellowing linear amino-modified silicone oil and its microemulsion preparation method and application, and Chinese Patent Publication No. CN101565896A discl...
