Antimicrobial finish on fabrics

Abstract

A formulation is provided which comprises at least one phenolic compound in an amount of about 0.5 to about 1.2% of the mass of the formulation; at least one fragrance in an amount of about 0.3 to about 1.0% of the mass of the formulation; and at least one alcohol in an amount of about 90 to about 99% of the mass of the formulation. Said formulation is surfactant free and being capable of rendering anti-microbial finish to fabrics. And also, a process for preparing a fabric with anti-microbial finish is provided.

Description

FIELD OF INVENTION[0001]The invention relates to an antimicrobial finish on the fabric.[0002]This invention particularly envisages a durable antimicrobial finish and its application on the fabric.BACKGROUND[0003]Clothing and textile materials are not only carriers of microorganisms such as pathogenic bacteria, odor generating bacteria and mould fungi, but also good media for the growth of microorganisms. The inherent properties of the textile fibers provide room for the growth of micro-organisms. Humid and warm environment still aggravate the problem. Infestation by microbes cause cross infection by pathogens and development odor where the fabric is worn next to the skin. In addition, the staining and loss of the performance properties of textile substrates are the results of microbial attack. Obnoxious smell form the inner garments such as socks, spread of diseases, staining and degradation of textiles are some of the detrimental effects of bad microbes.[0004]Though the use of anti...

AI Technical Summary

Benefits of technology

The present invention provides a fabric with an anti-microbial finish that is durable and does not change the appearance, color, or feel of the fabric. The fabric is also safe for humans and the environment. The finishing treatment is called decatising and involves heat, moisture, and pressure to stabilize the fabric's physical and dimensional properties. This treatment can improve the fabric's handle, lustre, and smoothness, and it also helps to prevent fuzzing or shrinking during use.

Problems solved by technology

Infestation by microbes cause cross infection by pathogens and development odor where the fabric is worn next to the skin.

In addition, the staining and loss of the performance properties of textile substrates are the results of microbial attack.

Obnoxious smell form the inner garments such as socks, spread of diseases, staining and degradation of textiles are some of the detrimental effects of bad microbes.

ii) Nano silver has also some adverse effect on wound.

Increase in mass usage of Silver treated AMB fabric and the effluent generated during home laundering of garments may contaminate soil / water.

Nanosilver can not be filtered out fully in Effluent Treatment Plant (ETP) and likely to cause soil and water contamination.

Also the presence of Silver ion in the effluent water increases the load on Effluent treatment plant substantially.

Nano-silver ion based AMB technology has been known to require several precautions in application as well as many costly modifications in effluent water treatment process.

Other chemical used for producing durable antimicrobial (AMB) fabric is 3-trimethoxy silyl propyl dimethyl octadecyl ammonium chloride—but it has also some disadvantagesyellowing of the shade / colour of the fabric.it is a cationic compound—If any anionic detergent is used during home laundering, it will take out the cationic compound from the fabric making the anti-microbial effect less durable.

The textile or fabrics containing antimicrobial agent disclosed in the above prior art does not provide effective and long lasting anti-microbial activity.
