AI Technical Summary
Technical Problem
Existing technologies struggle to improve the whiteness of seaweed fiber blended fabrics without damaging the seaweed fibers, as traditional bleaching processes can lead to structural damage and gelation of the seaweed fibers.
Method used
A mixed bleaching solution consisting of low-concentration alkali and water-soluble aluminum salts and bleaching agent is used, combined with temperature control and post-treatment processes, including bleaching at 90-95℃ for 30-60 minutes, followed by washing with hot water and room temperature water, and finally drying.
Benefits of technology
It achieves high whiteness bleaching of seaweed fiber blended fabrics, reduces fiber loss, and is environmentally friendly and pollution-free, making it suitable for industrial applications.
