Title:
STAINED P3HB3HH-BASED FIBERS, FIBER AGGREGATE INCLUDING SAME, AND METHODS FOR MANUFACTURING THESE
Document Type and Number:
WIPO Patent Application WO/2024/058076
Kind Code:
A1
Abstract:
The present invention addresses the problem of staining, with excellent stain adhesion, poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)-based fibers while reducing the amount of energy required for staining. The present invention provides stained poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)-based fibers, a fiber aggregate, and methods for manufacturing these, characterized by including a step for staining poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)-based fibers, and further characterized in that the staining is carried out at a temperature of 85°C or lower using a dye.
