Abstract
A flexible container in the form of a bag is described for use in a non-immersion dry cleaning process. Bag walls that are appropriately stiff and slick are preferred (preferred Kawabata Evaluation System stiffness and surface friction values are given), as are bag designs that are inherently three-dimensional and self-supporting. A preferred embodiment is a tetrahedral bag having a slick polymeric coating on the interior surface.
Claims50
A containment bag for articles to be cleaned in a non-immersion textile cleaning process, said cleaning process comprising placing articles to be cleaned into said bag through an opening having a closure means, securing said closure means, and subjecting said articles within said bag to a tumbling action in the presence of a cleaning agent, wherein said bag, when empty and with said closure means secured, readily defines an enclosed space having a predetermined three-dimensional shape, said bag having an inherent structural rigidity whereby said enclosed space is maintained sufficiently to promote, during said cleaning process, the free tumbling of articles placed in the bag.
A containment bag for articles to be cleaned in a textile cleaning process, said cleaning process comprising placing articles to be cleaned into said bag through an opening having a closure means, securing said closure means, and subjecting said articles within said bag to a tumbling action in the presence of a cleaning agent, wherein said bag, when empty and with said closure means secured, readily defines an enclosed space having a predetermined three-dimensional shape, said bag having bag walls that contribute to said bag having an inherent structural rigidity whereby said enclosed space is maintained in said predetermined shape sufficiently to promote, during said cleaning process, the free tumbling of articles placed in the bag, wherein said bag walls are comprised of a textile composite, said composite comprising a textile substrate having a polymer facing.
The textile substrate of claim 36 wherein said polymer facing forms anchoring structures that penetrate and extend through said substrate from the facing side to the opposite side of said substrate, said anchoring structures terminating on said opposite side being sized and shaped to resist retraction from said penetrated substrate.
A textile composite for constructing an inherently three-dimensional containment bag for use in a non-immersion dry cleaning process, wherein said composite is comprised of a textile substrate with a surface carrying a polymer facing, said composite having a minimum average Kawabata stiffness value of at least about 0.6 gms (force) cm2/cm. and wherein the surface carrying said polymer facing has a maximum average Kawabata surface friction value of about 0.35.
A textile composite for constructing an inherently three-dimensional containment bag for use in a non-immersion dry cleaning process, wherein said composite is comprised of a textile substrate with a surface having a polymer facing, said composite having a minimum average Kawabata stiffness value of at least about 1.0 gms (force) cm2/cm.
