Owari Textile Research Center develops simulation-system
for fabric shape deformation.
The Owari Textile Research Center of the Aichi Industrial Technology Institute has developed a new simulation method with a computer which estimates fine surface dimensions and shape deformation of fabric when used for the curved surfaces of things such as car seats. With this method, it is possible to check three dimensional shape and deformation of fabric without actually weaving and applying the fabric to a curved surface, which makes it possible to shorten the development period considerably for automobile interior fabric material and the like.

Toray develops mass production technology for carbon composite material
comparable to mass production of plastic and metal.
Toray has for the first time in the world successfully developed a new mass production technology with carbon composite material (CFRP, carbon fiber reinforced plastic) by which industrial goods with complex shapes can be mass produced. According to them, the degree of freedom of design and mass production comparable to other industrial materials such as plastic or metal was realized by fundamentally reviewing CFRP from material design to production methods.
Dai-ichi Kogyo Seiyaku puts new TCG spray-on gel products on sale.
Dai-ichi Kogyo Seiyaku (H.O.: Chuo-ku, Kyoto) has released NANOWORP and CELLODIENU 4M, new Transparent Cellulose Gel (TCG) products.
According to their announcement, NANOWORP and CELLODIENU 4M are nanosize particles dispersed in water without losing the characteristics of cellulose as a natural material. These particles keep high viscosity by turning into a gel under static conditions, they have the unique characteristic of decreasing viscosity significantly under high shearing force, which other acrylic gelling agents and cellulose materials do not have. With this characteristic, they show an unprecedented feature, a gel which can be sprayed.
Particles can be dispersed not only in water but alcohol and oil since they have cellulose-specific high hydroxyl interaction, which makes it possible to combine pigments and dyestuffs. The gel shows excellent emulsifying properties when used by itself or with other emulsifying agents.
Teijin Fibers develops high-class woolen-type material to use in black formal wear.
Teijin Fibers (H.O.: Chuo-ku, Osaka) has developed “BARTLETT,” a high-class woolen-type material to use in black formal wear, and will promote it for ladies black formal wear (blouses, suits and jackets).
According to them, “BARTLETT” has spaces between its molecular crystals created with nanotechnology. They have developed a polymer with unprecedented high deep-dyeability. The delicacy of high-class extra fine wool and high deep-dyeability were realized at the same time using special false-twist textured technology.
Seiren to build Fukui head-office building
rising 10 stories above the ground due for completion in January 2008.
Seiren(established in 1889) is celebrating its 120th year in business in 2008.They will build a new head-office building at their current Fukui head-office site (1-10-1, Keya, Fukui) as part of the memorial project.
They expect construction of the new head-office building to begin in December 2006 and to be completed in January 2008. It rises 10 stories with a building area 1,607m2 and an architectural area 11,689m2. The investment amount for the building including environmental development business is approximately 3.5 billion yen, and they are planning to invite tenants for some parts of the building and to be rented out.
Increasing tone of necessity of environmental measures in China,
because of increases in dyeing and finishing in coastal areas.
The total amount of dye-polluted water is increasing in China because of increases in dyeing and finishing. The processing tasks of effluent treatment facilities have been in full swing because the number of dyeing and printing firms is increasing in coastal areas in China especially. The number of articles by scholars specializing in textiles is on increase which suggests various items such as ① subsidizing the expense of wastewater treatment easily with attempts to make a shift to dyeing and printing with high added value and ② making an effort to reduce the amount of wastewater discharge with innovating dyeing and printing processing technology.
Maya Trading starts promoting innovative hydrogen peroxide
bleaching method for China.
Maya Trading (maya@fine.ocn.ne.jp) has begun the promotion of a special enzyme for the environmental control law in bleaching knitted cotton with hydrogen peroxide for the Chinese market. When knitted cotton is bleached with hydrogen peroxide, the dyeing process proceeds while the fabric is still wet after bleaching; however more than 10 ppm hydrogen peroxide may remain even after rinsing. Because of that, there are some problems such as causing dyeing failure reacting with the reactive group of a reactive dye. To solve those problems, sodium thiosubsulfate had been used for removing residual hydrogen peroxide in the past. However, since it is a reducing agent, unreacted sodium thiosubsulfate remains which adversely affects dyeability. Maya Trading has confirmed excellent bleaching effects and good results in improving dyeability at post-process with parallel usage of the special enzyme CTM 3000 conc. as a countermeasure for this problem. It has the characteristics to make a significant contribution to environmental measures.
Major textile firm in Iran shows interest in Japanese continuous processor for 3-D patterns.
Iran’s major textile firm checked the contents on the HP of textileinfo.com. which introduced “Cubitex,” a continuous processor developed by Chuo Giken Ind. of Japan, which enables the expression of 3-D patterns, and contacted the developer Chuo Giken Ind. regarding the price, showing interest in the equipment.
