An "OBA for silk nylon fabric" refers to an Optical Brightening Agent specifically designed for use on fabrics made from a blend of silk and nylon, which works by absorbing invisible ultraviolet light and re-emitting it as visible blue light, making the fabric appear brighter and whiter; essentially enhancing the whiteness of the silk-nylon blend by counteracting any yellowing tendencies with a bluish hue. Key points about OBA for silk nylon fabric: Function: It absorbs UV light and emits visible blue light, creating a perceived "whiter" appearance on the fabric. Application: This type of OBA is typically added during the fabric finishing process in the textile industry. Compatibility: It is formulated to be suitable for both silk and nylon fibers, without damaging the fabric. Benefits: Enhances the overall whiteness of the silk-nylon blend. Can make the fabric appear cleaner and fresher. Provides a more aesthetically pleasing look. ;

Reactive Black WNN is a reactive dye, meaning it forms a strong bond with the fiber, resulting in high washfastness and good lightfastness. It's a popular choice for dyeing cotton, linen, rayon, and other natural fibers due to its ability to produce deep, rich black shades. It's also suitable for textile printing. Key Details and Usage:Type: Reactive dye, a type of dye that forms a chemical bond with the fiber. Color: Black, with both reddish and greenish tints. Applications: Textile dyeing and printing, particularly for cotton fabrics. Fibers: Suitable for natural fibers like cotton, linen, and rayon. Fixation: Reactive dyes form a strong covalent bond with the fiber in the presence of alkali, a process called "fixing".
