Tochisen Co., Ltd.

We have established a method for dyeing polyester films with water solvent.

Our company is the only film dyeing company to establish a method for dyeing polyester films with water solvent. The main characteristics of this dyeing method are that it retains the film’s high transparency and the texture of the base material. We also sell C-mal automobile window films and other original products. We provide saponification of TAC films, which are necessary for polarizing plates, and we are one of Japan’s few saponification providers. We have increased our focus on developing new products and technologies since acquiring ISO 9001 certification, especially in the medical field.

[Company strength]
The main characteristics of our dyeing method are that it retains the film’s high transparency and the texture of the base material. The solvent dyeing methods applied by our competitors use specific types of dyes (limited color choice), and are not suited to small-lot production. Their high treatment temperature is also disadvantageous as it can only treat polyester films and nothing else. Our dyeing method makes it possible to use commonly available disperse dyes. We can combine a disperse dye with other types of dyes to control the wavelength, and dye various films other than polyester film. 



[Business description]
Our company is the only film dyeing company to establish a method for dyeing polyester films with water solvent. We have been dedicated to textile and knot processing since our establishment in 1943. Currently we mainly offer chemical film dyeing, and sell original products such as C-mal automobile window film. We also provide saponification of TAC films, which are necessary for polarizing plates, and we are one of Japan’s few saponification providers.

[Company structure for market development/overseas expansion]
We have nine dyeing machines to choose from depending on the production volume, even in small lots. We possess both ordinary dyeing machines and high-pressure dyeing machines that handle deep colors and highly light-resistant dyeing. We have built up expertise in textile dyeing in many years of operations. This is how we can suggest a suitable dyeing method for each company taking various factors into consideration, including lot size, high mix production, quick delivery, and the environment. We can realize the exact product development operations for our customers by using film with appropriate properties for the given needs.
