Japan Toray develops new fabrics that can be easily decontaminated

The Toray company of Japan developed new material "stain off" that can easily remove dirt from dirty collars. The plan is to start sales of sportswear in autumn and winter 2008, and then expand into areas such as women's and men's popular clothing and uniform use. Sales volume will be 500,000 meters in the first year and 2 million meters three years later.

“Decontamination” refers to a plurality of soil components such as sebum, proteins, and floating matter in the atmosphere, and physically rubs the collar dirt that is difficult to remove, and can be easily removed by any of the methods of home washing, industrial washing, and dry cleaning. Polyester, nylon and various natural fibers mixed woven fabrics, knitted fabrics new material.

This material is easily compatible with the washing solution (water, solvent, etc.) during washing, and a remover (SR agent) that can easily remove collar stains is used. During washing, the SR agent adsorbs the cleaning solution and expands, pushing away the dirt attached to the collar and making it easy to leave the fiber. In addition, this kind of SR agent adopts Toray's original nanofabrication technology “Nanomatrix” to adhere a uniform film (thin-swelling type special SR film) having a number of thickness + nm to one filament constituting a single fiber. As a result, compared with the conventional method of coating on the surface of a fabric, it is difficult to cause the homogenizing agent exerted by the function due to uneven adhesion to fall off, and it is possible to continue to maintain a high effect for a long period of time.

Furthermore, because this technology is not only a synthetic fiber such as polyester, but also natural fibers such as cotton can be processed. Needless to say, shirts that are repeatedly washed in daily use can generally provide functions such as down jackets that are often washed about once in the first quarter. In addition, cosmetic dirt that contains sebum similarly to the collar can also exert its effect.

Dirt is inevitable when it comes to clothes. Simply removing these dirt is generally a topic of high concern. Heretofore, there have been various treatment methods such as the use of a protection method using a spray or the like and a method of performing partial cleaning using a special detergent before washing. These methods require extra time and are cumbersome. In addition, from the standpoint of the durability of washing and the like, it is rarely the case that the material for dealing with collar dirt is the actual situation to date.

Toray company is promoting "5 innovations and 8 company-wide projects" in its mid-term management project "Project Innovation Innovation" (IT-2010). This new material is a response to the “customer” demand for collar fouling countermeasures using the core technology of our company, such as nanotechnology, and reflects two items of “business innovation” and “research and technological innovation”.

Toray will continue to drive the company's technological development, realize the excellent functional materials required by the society, and strive to participate in the creation of new values ​​of “Innovation”.
