Standards Development

Scope

This document specifies testing methods for determination of reduction activity of textile products against specific proteins which shows antigen-antibody reaction. This document specifies just only the reduction activity against those proteins on the surface of textile products, and it is not a testing method to evaluate the allergenic reaction against human beings.

Enzymed-Linked Immunosorbent Assay is used to quantify the amount of those proteins in this document.

The textile products include woven and knitted fabrics, fibres, yarns, braids, etc.

Purpose

Recently, along with the global improvement in the level of living, consumers are showing the trend to seek a comfortable and hygienic life.

Speciality textile products which can have the positive effect on human comfortable and hygienic life such as anti-bacterial, anti-fungal, anti-viral treated textiles have been introduced in the market are expanding year by year in various applications.

Now, Contamination on textile products with specific proteins which show antigen-antibody reaction also can have the negative effect on human comfortable and hygienic life. There are high performance textile products which can reduce the amount of those specific proteins on textile products. Because those products are relatively new and included the technical aspects out of textile technology, the testing methods have been developed by the individual procedures to evaluate the product performance. That has resulted in inexistence of a unified test method, hindering for both consumers and producers a true explanation or understanding of those functional products. The textile product capable of reducing the amount of specific proteins is one of those products and includes the technical fields of textile technology and biotechnology.

The demand to establish an international standard has been growing in the consumers, retailers, producers, etc. as stakeholders in the market.

This document provides a quantitative test method by using Enzymed-Linked Immunosorbent Assay to assess the reduction activity of the specific proteins on textile products by taking proteins derived from pollen and mite-feces or carcass as an example.
