This report is a summary of the finishing methods for an antimicrobial and deodorant, microbial control and deodorant finished textile products, trends in the development of the market and their future prospects.
1. The three kinds of finishing methods for textiles ; the antimicrobial and deodorant, microbial control and deodorant finishing, have been explained in terms of the trend of these processing technologies given as examples.
2. The main antibacterial test methods were introduced in a test of East Asia (Japan, China, and South Korea) and the international standard ISO 20743.
3. The textile producers from many companies were introduced with the development of the market.
4. The following important matters were pointed out for the future trend.
a) Recent social conditions have seen the arrival of the aged society, where the senior citizen and pivot care senior citizen population has increased rapidly. Thus antimicrobial and deodorant, microbial control and deodorant finished textile products associated with measures to control decubitus and unpleasant odor has become very important.
b) Three issues ; health, comfort and health care, have become the keywords for the development trend of high functional finished textile products recently.
c) It is important for the textile companies in our country to strengthen their policy in terms of the following nine aspects, as well as to positively cooperate with the emerging countries such as China and India while leading the world.
1) Maintain cost competitiveness and quality domination, 2) Correspondence of QR (Quick Response) and maintenance of product development power, 3) Diversification of business and globalization of management, 4) Correspondence to the earth environmental issues, 5) Substantiality and promotion of fundamental research in the textile field, 6) The advancement and innovation of technology in textiles and its related fields, 7) Cooperation with different kinds of industries toward new consumer needs, 8) Promotion of international joint development, 9) Reinforcement of protecting intellectual property rights

Eight years have passed since the Japan Textile Evaluation Technology Council started the certification system of the deodorant-finished products mark by adapting both test methods of sensory analysis and instrumental analysis. Although the range of the certified products covers almost all textile uses, the deodorant category only covers smell of sweat and body odor alterations during aging. For certification, it is necessary to conduct expensive sensory analyses on a plurality of odor sources, requiring large burden of expenses. Therefore, efforts have been made in that the certification only with instrumental analysis has started for some odor sources for which correlation data of both analyses have been accumulated for improving reliability.

New techniques of synthesizing antibacterial fiber attached on silver nanoparticles have been developed. Irradiation on aqueous solution containing silver ion induces reducing reaction to form metallic silver nanoparticles. The silver particles are firmly immobilized on the surface of the fiber. Silver nanoparticles with high antibacterial activity are attached onto the fiber surface without any binder. The antibacterial fiber showed high antibacterial activity and durability.

Recently Japanese consumer’s demands for amenities have been increased and they pay more attentions to their body odors. Therefore various deodorant-finished fibers and fabrics have been developed. In such a background, we had examined deodorant finish and fungicide deodorant finish for wool fabrics. In results we succeeded in developing “Deodorant Finish ; Self-Etiquette” and “New Deodorant & Fungicide deodorant Materials ; V-CAT^® Finish”. In this article, we explain about the performance of deodorization which wool originally has, and the processing of deodorant finish on wool fabrics.
