Antibacterial Finishing Method of Hotel Linen


The arrival of the COVID-19 epidemic has seriously affected the survival and development of the hotel accommodation industry. At the same time, it also puts forward higher requirements for the maintenance, cleaning and selection of linen. Today, SIDEFU shares with you the knowledge about antibacterial textiles. General textiles do not inhibit and kill bacteria, and are often considered as a good medium to nourish microorganisms. Under appropriate temperature, humidity and corresponding nutrients, microorganisms can rapidly grow and reproduce. Porous textiles are very easy to absorb excreta secreted by human sweat glands and spleen glands, providing nutrients for microorganisms. Therefore, textiles are the supporters of microorganisms to some extent.

The presence of microorganisms on textiles not only affects its performance, causes the formation of plaques, and makes textiles mildewed, brittle and even deteriorated, but also brings discomfort to users, and even harmful irritation to the skin, causing skin diseases and endangering human health. In addition, ammonia and other odor substances produced by microorganism decomposition of human secretion also seriously affect the surrounding environmental health.


Therefore, it is necessary to carry out antibacterial finishing on fabrics, which can hinder and inhibit the metabolism and reproduction of microorganisms during the use and storage of fabrics.

At present, there are many antibacterial finishing agents, which can be mainly divided into inorganic, organic and natural antibacterial agents.

1、Inorganic antibacterial agent

Most of them are metal ions, some photocatalyst antibacterial agents and composite finishing antibacterial agents. Antibacterial ingredients mainly include some metal ions, such as Pd, Hg, Ag, Cu, Zn and their compounds, which can denature or inactivate bacteria by combining with cell proteins in bacteria.

2、Organic antibacterial agents

Most of them are traditional antibacterial agents, mainly composed of organic acids, phenols and alcohols, including quaternary ammonium salts, organosilicon quaternary ammonium salts and guanidine (PHMB).

3、Natural antibacterial agents

It mainly includes chitin, chitosan, plant extracts, etc.

Antibacterial processing methods of textiles mainly include blending, spinning and finishing.

1、Blending method

The antibacterial agent is mixed with various additives, and then mixed evenly with the fiber matrix resin, and the antibacterial fiber is prepared by melt spinning. The antibacterial component of the antibacterial fiber prepared by this method exists on the surface and inside of the fiber at the same time, and is evenly dispersed. It is mainly used in non active side base fibers such as polypropylene fiber and polyester fiber, and is suitable for the production of antibacterial textiles for medical, clothing and home textiles.

2、Post finishing method

Antibacterial finishing agent is used to treat the fabric in the post finishing process, so as to give it antibacterial efficacy. This processing method is mature and simple, but its disadvantage is relatively poor durability.


As mentioned above, due to the particularity of washing and maintenance of hotel textiles, in general, antibacterial finishing is not recommended for all cotton and regular washing products with polyester content less than 40%; For commonly washed products with 40-50% polyester content, such as piece and set textiles and toilet textiles, it is recommended to use the co blend spinning method to process antibacterial products, such as the antibacterial textiles produced by spinning and weaving of polyester staple fibers made of natural antibacterial agents such as wormwood, aloe and cotton fibers after mixing them, after washing, they still have a good inhibitory effect on Escherichia coli, Staphylococcus aureus and Candida albicans.

For core products with a long washing cycle, the surface can be made of fabric by blending spinning or finishing, and the filler can be made of antibacterial polyester fiber by blending spinning.


In recent years, the antibacterial finishing technology of fabrics at home and abroad has become increasingly mature, and antibacterial products have been continuously applied in various fields. The research and application of antibacterial materials have a good development prospect. Unfortunately, as antibacterial property belongs to a recessive function of textiles, it is invisible and intangible. At present, it is rarely used in hotel linen. With the enhancement of people's awareness of environmental protection and health, and the deepening of research on high safety, low toxicity and high temperature resistant antibacterial agents, antibacterial textiles will be widely used in hotel linen.
