Abstract: Environmental protection is a global objective and a key factor in future development. Decreasing volatile organic compounds and replacing fossil-based materials are considered huge challenges in the ecofriendly polyurethane (PU) industry. Although replacing solvent-based PU by water-based polyurethane dispersions (PUDs) is crucial, PUDs still contain some organic solvents, which should be removed by vacuum evaporation. In addition, the use of biobased materials derived from renewable sources instead of fossil-based materials is considered an ecofriendly technique. In this study, we synthesized biobased PUDs with a biomass polyether diol (polypropanediol H1000) through a patented solvent-free process without the addition of any organic solvent. We synthesized a series of solvent-free biobased PUDs by using H1000 incorporated with fossil polyether diol (poly(tetramethylene ether) glycol T1000) with various biocontents of formulation (60, 50, 40, 30, and 0 wt.%). When using biobased 60 wt.% PUD, Bio60-H100, the adhesion force is higher than fossil materials source, Bio0-H0 by cross-cut and scrub test. This is because of the high ether group concentration and increased number of intermolecular hydrogen bonds in H1000. As indicated by stress–strain curves, the toughness of the PU films from hard to soft when the ether group concentration of PU soft segments increased. In addition, the solvent-free biobased PUDs were flexible, exhibited superior softness, and demonstrated increased tear strength on recycled polyester fabric with a fluoride-free water-repellent agent (C0 W/R). In summary, we developed a series of high-biocontent environment-friendly solvent-free PUDs with favorable storage stability, which can be used in textile coating in the sustainable fabric industry.
