Abstract: Disclosed is a process for printing on polyester fabric comprising (1) contacting polyester fabric with an aqueous solution comprising (A) 5% to 35% by weight of at least one multivalent cationic salt; (B) 0.1% to 5% by weight of a blocked polyisocyanate crosslinking agent, and (C) 3% to 40% by weight of a waterborne resin, all percentages based on the weight of the aqueous solution; (2) drying the polyester fabric to remove the water from the polyester fabric; and (3) digitally printing the pretreated and coated polyester fabric with a water-based textile ink.

Abstract: Methods for storing and moving adhesive particulate to an adhesive melter are disclosed. An interior space of a supply hopper is filled with adhesive particulate. A transfer pump is actuated to generate a vacuum at an inlet of the transfer pump to actuate removal of the adhesive particulate from the supply hopper. A consistent minimized depth of the adhesive particulate located directly above the inlet is maintained with a shroud located within the interior space of the supply hopper. In addition, adhesive particulate can be received in an interior space of a container. An open space is maintained within the interior space of the container proximate the pump inlet, where the open space entrains gas to be drawn by the transfer pump. The transfer pump can be actuated to generate a vacuum at the pump inlet to cause removal of the adhesive particulate from the container.

Abstract: An adhesive bin (10) for storing and moving adhesive particulate (14) to an adhesive melter (12) includes a supply hopper (16), a transfer pump (62) operable to generate a vacuum, and a shroud (94). The supply hopper (16) has a sidewall (20, 22, 24, 26) and defines an interior space (36). The transfer pump (62) extends through the sidewall (22) and into the interior space (36). In addition, the shroud (94) is connected to the sidewall (22) and extends into the interior space (36) and at least partially surrounds an inlet (82) of the transfer pump (62).

Abstract: Disclosed is a pretreatment solution for treating a fabric before inkjet printing comprising an aqueous solution of (A) 1% to 60% by weight of at least one multivalent cationic salt; (B) 0.2% to 10% by weight of at least one acid; and (C) and 0.5% to 5% by weight at least one borate, all % are by weight of the aqueous pretreatment solution.
