  • Publication number: 20250360488
    Abstract: The present invention relates to a bio-based and biodegradable superabsorbent polymer (SAP) comprising sodium alginate, modified cellulose, at least one activation agent, and at least one crosslinking agent. The SAP exhibits a high bio-based content of up to 93% and fulfills industrial composting standards such as EN 13432. The crosslinking reactions are performed under mild conditions, including ambient temperatures and neutral to alkaline pH, eliminating the need for high thermal energy. The resulting SAP granules demonstrate excellent liquid absorption performance, rapid swelling, high retention, and no observed toxicity or skin sensitization. The invention provides a sustainable alternative to petroleum-based SAPs for use in hygiene products, agriculture, and other disposable applications.

  • Publication number: 20240352267
    Abstract: The present invention relates to a screen printing formulation a method of processing a heat transfer with the screen printing formulation for use in garment industry. The raw materials of the screen printing formulation are derived from renewable plant-based resources. It can be printed and cured by adopting current heat transfer processing technology with comparably short curing time of 0.5 hour. The cured screen printing formulation contains bio-based content as high as 93% with strength and elasticity comparable with typical TPU counterparts. The bio-based heat transfer can perform comparable performance comparing with fossil-based polyurethane and silicone heat transfer. Moreover, when applying the bio-based heat transfer on garments or fabrics, it is able to adhere firmly without peel off, cracking, shrinkage, wrinkle and color migration even after repeated laundry wash and dry, fulfilling quality standard tests of garment industry.
