[Features] ■ A processing agent capable of deodorizing unpleasant odors ■ Primarily effective against sweat odor, nonenal odor, and aldehyde odor ■ Can address a wide range of odors through combination ■ One-bath treatment possible in conjunction with our cellulose fixative due to the product's ionic nature ■ Improved wash durability when used with a binder *For more details, please refer to the PDF document or feel free to contact us.

The "Senshil AFU-05" is an antibacterial deodorizing agent made from citrus extracts. It prevents the generation of unpleasant odors by inhibiting the growth of bacteria on fibers through its antibacterial properties. The main components are fatty acids and flavonoids, which are believed to act on the cell walls of gram-positive and gram-negative bacteria by precipitating the proteins in their cell membranes, thereby inhibiting their vital activities. 【Features】 ■ Antibacterial agent made from citrus extracts ■ Exhibits excellent antibacterial effects against a wide range of gram-positive and gram-negative bacteria ■ Does not inhibit the water absorption of treated fabrics ■ Provides excellent antibacterial and deodorizing effects with wash durability for various textile products *For more details, please refer to the PDF document or feel free to contact us.

The "Senshilu AFU-08" is an antibacterial and deodorizing agent for fiber processing that prevents the generation of unpleasant odors by suppressing the growth of bacteria on fibers. It meets the SEK mark certification standards in the JIS L 1902:2015 bacterial liquid absorption method. It provides excellent durability and antibacterial deodorizing effects without the use of binders for both natural and synthetic fibers, demonstrating high antibacterial effectiveness against Staphylococcus aureus (Gram-positive bacteria) and Klebsiella pneumoniae (Gram-negative bacteria). 【Features】 ■ Shows high antibacterial effectiveness against Staphylococcus aureus (Gram-positive bacteria) and Klebsiella pneumoniae (Gram-negative bacteria). ■ Provides excellent durability and antibacterial deodorizing effects without the use of binders for both natural and synthetic fibers. ■ Meets the SEK mark certification standards in the JIS L 1902:2015 bacterial liquid absorption method (antibacterial deodorizing treatment, antibacterial treatment for general use). *For more details, please refer to the PDF document or feel free to contact us.

The "Cheer Cut CF-2" is a chlorine resistance improving agent that significantly enhances the chlorine fastness of reactive dye fabrics. It has excellent wash fastness, withstands water flow tests, and shows minimal reduction in light fastness. Additionally, it can be used in the same bath treatment with other fixing agents and finishing agents. 【Features】 ■ Excellent chlorine fastness improvement effect for cellulose/reactive dye fabrics ■ Good wash fastness and withstands water flow tests ■ Minimal reduction in light fastness ■ Can be used in the same bath treatment with other fixing agents and finishing agents ■ Applicable for both exhaustion treatment and pad treatment *For more details, please refer to the PDF document or feel free to contact us.

"ACB-74" is a peroxide bleaching accelerator that demonstrates a high bleaching effect at lower temperatures or shorter times when added to a bleaching treatment bath using hydrogen peroxide. It reduces energy costs and processing time, enabling more sustainable processing. Through energy reduction and shortening of processing time, it contributes to the achievement of SDGs (7, 9, 13). 【Features】 ■ Efficiently consumes hydrogen peroxide, improving efficiency by 19% ■ Reduces energy costs and processing time, enabling more sustainable processing ■ Processing at low temperatures and short times suppresses the brittleness of cotton due to the bleaching process ■ Activated hydrogen peroxide decomposes, and bubbles increase in the treatment bath *For more details, please refer to the PDF document or feel free to contact us.

"Unional RNC" suppresses the contamination of reactive dyes on nylon in nylon-cellulose mixed dyeing, making it easier to achieve uniform coloration. It does not adversely affect lightfastness. Additionally, it has low foaming properties and excellent salt resistance (resistance to Glauber's salt). 【Features】 ■ Suppresses contamination of reactive dyes on nylon ■ Does not negatively impact lightfastness ■ Low foaming properties ■ Good salt resistance *For more details, please refer to the PDF document or feel free to contact us.

"Penetogen E-51" is a degassing, defoaming, and penetrating agent that demonstrates effectiveness with a low additive amount. It is effective not only in water but also in the penetration of dyes, and due to its nonionic nature, it has good compatibility with nitrogen-containing leveling agents. Additionally, it has low foaming properties and excellent defoaming capabilities, contributing to the improvement of dye unevenness caused by foam generation or insufficient penetration. 【Features】 ■ Effective with a low additive amount ■ Effective not only in water but also in the penetration of dyes ■ Good compatibility with nitrogen-containing leveling agents due to its nonionic nature ■ Low foaming properties and excellent defoaming capabilities ■ Capable of achieving both penetration and defoaming effects ■ Contributes to the improvement of dye unevenness caused by foam generation or insufficient penetration *For more details, please refer to the PDF document or feel free to contact us.
