Textile Auxiliaries
Dai-ichi is a well-recognized manufacturer of high-quality fiber and fabric processing chemicals, catering to the diverse needs of the textile industry. Our extensive range of textile auxiliaries supports both natural and synthetic fibers, including cotton, polyester, acrylic, nylon, wool, and more. We offer specialized processing auxiliaries designed to optimize each stage of textile production, from wetting and scouring to mercerizing, chelating, dispersing, and peroxide stabilization. Our dyeing auxiliaries ensure vibrant, uniform colors, while our dye-fixing agents provide lasting colorfastness. Additionally, our finishing chemicals impart desirable qualities such as softness, smoothness, and durability to the final fabric, enhancing the overall quality of textile products. Whether for traditional or modern textile manufacturing processes, Dai-ichi’s textile auxiliaries are engineered to deliver superior performance and consistent results.
Pretreatment Auxiliaries
Dai-ichi offers superior auxiliaries for various stages of textile wet processing. Our formulated blends of ethoxylates and other compounds include wetting agents for the mercerization process, ensuring uniform penetration of caustic liquor into cellulosic substrates, which imparts luster and enhances dyeability. Additionally, our APEO-free wetting agents for scour-bleach processes provide excellent absorbency and whiteness to all types of substrates, with low foam properties suitable for high-turbulence machines. We also offer high-performance chelating and dispersing agents that control water hardness, chelate heavy metal ions, and improve the efficiency of bleaching processes. Moreover, our stabilizers for alkaline bleaching ensure efficient peroxide utilization, preventing pinholes and minimizing strength loss in fabrics.
Dyeing Auxiliaries
Our range of leveling agents, soaping agents, and dye-fixing agents is designed to enhance the dyeing process for polyester substrates with disperse dyes and for cotton substrates with reactive dyes. These leveling agents effectively control dyestuff exhaustion rates and ensure even dyeing shades. Our soaping-off agents are excellent for reactive dyeings and prints, ensuring the efficient removal of reactive dye hydrolysates while improving fastness properties and increasing the brilliance of shades. Additionally, our non-formaldehyde dye-fixing agents enhance wash, crock, water, and perspiration fastness properties, with minimal impact on shade change and light fastness.
Finishing Auxiliaries
Our pseudo cationic softeners are hydrophilic, non-yellowing, and available in liquid form as 100% concentrated products. solutions. These softeners are suitable for all types of textile substrates, imparting a soft and silky smooth handle to treated fabrics. They are particularly effective for terry towels and can be applied through both padding and exhaust processes, ensuring versatility in textile finishing.
Rayon Additives
Dai-ichi is a pioneer in developing and manufacturing specialty additives and finishes for regenerated rayon fibers and filaments. Our offerings include viscose process additives, which enhance various stages of production, as well as specialty finishes tailored for rayon filament yarn and rayon staple fibers. These products are designed to optimize the quality and performance of regenerated rayon, ensuring superior results in the final textile applications.
Viscose Process Additives
Dai-ichi offers a range of specialty performance blends designed as process additives for each stage of the viscose process. These include additives that improve the efficiency of dissolving pulp and the xanthation process, modifiers that enhance the tenacity of viscose staple fiber and viscose tire cord filament yarn, and additives that prevent zinc sulfide deposits in the spin bath to improve spinning efficiency. Additionally, our additives for the dope-dyed process help prevent the clogging of spinnerets, ensuring smoother and more efficient production.
Specialty Finishes for Viscose Filament Yarn
Our fatty derivatives serve as softeners and finishing agents specifically designed for rayon filament yarn used in spun yarn cakes. These agents enhance the softness and finish of the yarn, ensuring a high-quality end product in the textile manufacturing process.
Specialty Finishes for Viscose Staple Fibres
Our fatty nitrogenous derivatives act as fixatives for dope-dyed fibers, effectively preventing any color bleeding. These specialty finishes derivatives also include nonionic softening and brightening agents that create a scroop effect, imparting a silk-like character to the fibers. Additionally, they ensure smooth processing in subsequent operations within yarn spinning mills, enhancing overall efficiency and product quality.
Sizing Chemicals
Dai-ichi is a pioneer in developing and manufacturing specialty sizing chemicals and additives tailored for the synthetic yarn industry. Our product range includes advanced synthetic sizing agents based on polymeric compounds, designed to enhance the strength and performance of synthetic yarns during weaving. Additionally, we offer specialty additives such as antistatic and lubricating agents, which help reduce static buildup and friction, ensuring smoother processing. Our after-oil additive for sized yarn further improves the yarn’s finish, providing added protection and enhancing its overall quality. Dai-ichi’s innovative solutions are crafted to meet the specific needs of the synthetic yarn industry, ensuring superior results in every application.
Sizing Agents for Synthetic Yarns
Acrylic copolymer aqueous emulsions are used as synthetic sizing agents for water-jet looms, offering superior cohesiveness and making them suitable for high-density fabrics as well. These emulsions are ideal for polyester texturized yarn, polyester filament yarn, and nylon filament yarn, effectively preventing the occurrence of fabric cracks. They are also compatible with other size additives like waxes and antistatic agents and can be easily removed during subsequent desizing processes.
Specialty Size-bath Additives
Special lubricating waxes and antistatic agents serve as sizing assistants for water-jet and conventional looms. They provide enhanced lubricity, improve fiber-to-metal abrasion resistance, and reduce size shedding. The antistatic agents are particularly effective for warp sizing of man-made and synthetic yarns, preventing the generation of static charges during sizing, warping, and weaving operations, even at very low dosages.
After-Oil Additive for Sized Yarn
A blend of select lubricant oils serves as an outstanding after-oil lubricant for sized yarn, imparting cohesion and lubricity to treated yarn. It improves the abrasion resistance required for high-speed looms and is suitable for use with sized yarn, sized dyed yarn, and even unsized yarn.
