Abstract: A method for preventing a redeposition during washing of dyed fabric or garments made from natural and synthetic fibers is provided. The method may include admixing 0.1% to 1% of at least one anti-redeposition agent to an aqueous bath depending on the total weight of the dyed fabric to be washed. The anti-redeposition agent may include a water-soluble polyester made from bio-renewable raw materials. The water-soluble polyester may include a reaction product of a polyglycerol mixture, a sugar alcohol, a sebacic acid, and one of an unsaturated fatty acid, a saturated fatty acid, a fat or an oil, a polylactic acid, or polyhydroxyalkanoate.

Abstract: The instant invention discloses an enzyme-containing granule comprising: (a) a core granule comprising one or more enzyme particles; and (b) a water-soluble polymer coating therefor which substantially completely encapsulates said enzyme particles, wherein the polymer coating comprises a water-soluble or water-dispersible polyester resin, which comprises a reaction product of 20%-50% by weight of waste terephthalate polymer, 10-40% by weight of at least one glycol and 5-25% by weight of at least one oxyalkylated polyol.

Abstract: This invention relates to the synthesis from PET (virgin, recycled, post consumer, or precursor raw materials) of novel water dispersible or water emulsifiable polyester resins having improved hydrophobicity or non-polar characteristics. These characteristics give the applied film of these dispersions or emulsions much improved water repellency while at the same time retaining their redispersible or reemulsifiable properties. Such resins can be used for many applications in the paper, textile, coatings, paint, construction, and other industries.

Abstract: Water-soluble or water-dispersible and curable polyester resins are suitable as binders in various applications. The resins are reaction products of polyterephthalate, sulfoisophthalates, polyols, polyacids, end acids and crosslinker agents. Waste terephthalates can be utilized. The preferred polyol is pentaerythritol. The resins can also be used as dye levelling agents when dyeing synthetic fibers.

Abstract: An adhesive or coating composition comprises a reaction product of terephthalate polymer and mixture of glycols in the presence of a glycolysis catalyst. The reaction product is further reacted with a difunctional organic acid. The recycled polymer which is formulated as adhesive or binder can be used in many fields.

Abstract: A water-soluble or water-dispersible polyester resin composition, suitable for textile sizing applications, comprises a reaction product of 20-50% by weight of waste terephthalate polymer, 10-40% by weight of at least one glycol and 5-25% by weight of at least one oxyalkylated polyol. Preferred compositions also comprise 20-50% by weight of isophthalic acid. A further water-soluble or water-dispersible resin comprises a reaction product of 20-50% by weight of waste terephthalate polymer, 10-50% by weight of at least one glycol and 20-50% by weight of isophthalic acid.
