Abstract: The present disclosure provides methods for digital printing using modified indigo dye compounds.

Abstract: The invention generally relates to fabric dyeing, such as fabric dyeing using indigo or sulphur dyes. A process is provided which provides a dyed yarn having reduced dye penetration and a white core. The process involves modification of existing sulfur dye ranges to more efficiently and in an environmentally improved method produce dyed fabrics. The modification involves one or more of i) using of a barrier compound to subsequent dye applications; ii) performing a scouring stage without a caustic agent; iii) bypassing scouring and/or scour rising; iv) using sodium bicarbonate to control the pH of dye tanks; v) reducing the dye concentration and increasing the number of dye vats; and vi) adding a sizing stage to the dye range. The invention also is directed to yarns dyed on dye ranges through use of the process, and fabrics formed from the dyed yarns.

Abstract: The present invention relates to yarn dyeing, such as denim dyeing. A process provides a dyed yarn having reduced dye penetration and a white core at lower cost. The improved process for yarn dyeing is referred to herein as the CleanKore technology. The CleanKore technology improves one or more steps in dye ranges to achieve dyeing of the yarn while retaining a white core at the center of the yarn. When viewing a cross-section of a yarn, the peripheral portion is dyed while the center remains white (not dyed). The CleanKore technology modifies the scouring stage (or phase), the scour rinsing stage, the dyeing stage, and/or the dye rinsing phase of existing dye ranges. The modifications may be applied individually or any combinations thereof to the existing dye range.

Abstract: Ring dyeing of yarn with indigo dye to produce an improved white core, An outer surface of the yarn is scoured prior to applying the indigo dye, and then applying the indigo dye is applied. Scouring parameters of the dyeing are used to limit a penetration of the indigo into the white core, so that the white core has mostly sections of white yarn, and the yarn has indigo dye on the outer surface, said parameters comprising limiting scouring parameters to at least 10% below current parameters used to scour the yarn.

Abstract: Provided are methods for treating garments so as to improve color contrast, darkness, or both. Also provided are systems for treating garments as well as garments made according to the disclosed methods.

Abstract: Methods for treating a garment include: prewashing the garment; drying the garment in a first drying process; spraying a functional chemical onto the dried garment; and applying a curing treatment to the garment to cure the functional chemical. The method may further include drying the garment in a second drying process after spraying the functional chemical onto the garment.

Abstract: A card edge electrical connector is shown for providing electrical connections between a printed circuit card and a printed circuit board wherein the printed circuit card has either a 32 bit or a 16 bit capacity. The connector includes a housing having a retaining post that is inserted into an aperture of the printed circuit board to retain the connector to the printed circuit board. The retaining post is tubular having an axial slot extending through the sidewall thereof so as to be resilient and durable. Further, each of the contacts disposed within the connector housing includes a stabilizing arm that opposes the forces created by the insertion of the printed circuit card into the connector housing so as to distribute the opposing forces between the stabilizing arm and the base of the contact. Contacts of alternating sizes and having beams of different angles with the base are employed in the connector.
