Abstract: The present invention provides a nonwoven fabric comprising a non-fibrous binder having certain solubility characteristics. It also provides a pouched product, the fabric and contents of which have certain solubility characteristics. Related methods are also disclosed.

Abstract: A nonwoven fabric for use as packaging in an oral pouched product, where the nonwoven fabric comprises a web of chemically bonded staple fibres in which a relative proportion of staple fibres and a binder is selected in conjunction with a density of the fabric to strike an optimal balance in achieving a fabric that provides a soft (e.g. low friction) mouthfeel, a wet strength capable of withstanding manipulation in a user's mouth (e.g. chewing, sucking or the like), and a resistance to unwanted leaching or leaking of flavouring or other fine particle substances used in modern oral products.

Abstract: A nonwoven fabric for manufacturing an oral pouched product, where the nonwoven fabric is chewable to increase its liquid permeability. When the nonwoven fabric is used to form a pouch, it may thus control the release of substances from within the pouch. The nonwoven fabric can be formed by applying a diffusion restricting treatment to a base nonwoven fabric. The diffusion restricting treatment may include any of (a) incorporating a digestible compound; (b) incorporating a superabsorbent polymer; (c) incorporating a hydrophobic material; and (d) forming a deformable barrier layer.

Abstract: A method of inkjet printing includes the steps of: printing a first ink onto a print medium, the first ink including a first self-dispersible pigment, the first ink having a first pigment content A; and subsequently printing a second ink onto the print medium at least partially over the first ink, the second ink including a second pigment and a polymeric dispersant encapsulating the second pigment, the second ink having a second pigment content B. The first self-dispersible pigment and the second pigment have a same color; the pigment content A of the first ink and the pigment content B of the overprinted second ink have a relationship 0.8?A/B?1.2; and a polymer acid value of the polymeric dispersant is in the range of 100 to 170.

Abstract: A method of minimizing kogation of a heater element in a thermal inkjet printhead. The method includes the steps of: (i) supplying an inkjet ink to a nozzle chamber of the printhead; and (ii) repeatedly actuating a heater element in the nozzle chamber so as to heat a portion of the ink to a temperature sufficient to form a bubble therein, thereby causing droplets of ink to be ejected from a nozzle opening associated with the nozzle chamber. The ink includes a styrene-acrylic copolymer having a glass transition temperature (Tg) in the range of 5 to 30° C. and acid value in the range of 100 180 mgKOH/g, said styrene-acrylic copolymer minimizes kogation of the heater element.

Abstract: A solvent-based ink composition for a thermal inkjet printhead. The composition includes: (a) 10-80 wt. % of a compound of formula (B): wherein: R5 is a C1-6 alkyl group and R6 is a C1-6 alkyl group; or R5 and R6 are together joined to form a C3-12 cycloalkylene group; (b) 10-80 wt. % of a C1-6 alcohol; and (c) 0.01-25 wt. % of a surface-modified pigment.

Abstract: A solvent-based ink composition for a thermal inkjet printhead comprises a surface-modified pigment. The ink composition comprises: (a) 10-80 wt. % of a compound of formula (A); wherein: R1 is C1-6 alkyl; and each of R2, R3 and R4 is independently selected from H, C1-6 alkyl, halogen, OH, and C1-6 alkoxy; (b) 10-80 wt. % of a C1-6 alcohol; and (c) 0.01-25 wt. % of the surface-modified pigment.
