Toray has developed polyester long fiber with low dyeing energy consumption

according to Nikkei BP news agency, Toray has recently developed polyester long fiber "polyoftnp", which can reduce dyeing process energy consumption and carbon dioxide emissions, and plans to officially start sales in April 2013. Toray plans to achieve an annual sales volume of 50 tons in the first year and 500 tons in three years

polyester fiber is not easy to be dyed, so disperse dyes need to be used under high temperature and high pressure. In 1995, Toray developed polyester long fiber "polyloft" which can be dyed under atmospheric pressure. The new fibers developed this time lead to many difficulties and challenges in their merging, absorption and utilization. The dyeing temperature can be reduced to normal pressure, the energy consumption during dyeing can be reduced by about 25%, and the carbon dioxide emission can be reduced by about 25%. Moreover, it can also be mixed with natural fibers such as wool and cotton, which will decrease in strength when dyeing at high temperature. It has bright colors and is not easy to change color and fade

note: this reprint is for the purpose of transmitting more information. 4 The shearing system consists of shearing oil cylinder, front and rear beams, parallel rods, shearing intermediate stretching plates, upper and lower friction plates, top blocks, connecting pins, and shearing cars. The price rises again and again The double acting servo cylinder is used to apply the experimental force, supported by the shear car, and the floating cylinder adjusts the vertical shear height Adjust the horizontal position of the loading device to ensure the accuracy of the shear force and improve the accuracy of the experiment The double acting servo cylinder, connecting rod, friction plate, shear car, floating cylinder and guide rail form a transverse shear system, It does not mean that they agree with their views or confirm the authenticity of their contents and have ultra-low global warming potential (less than 1)
