  • Publication number: 20200063371
    Abstract: A tissue product is provided comprising a wet-laid sheet which comprises cellulosic fibers and cellulose ester staple fibers, wherein the cellulose ester staple fibers are present in an amount sufficient to provide the wet laid-sheet with a lower density and higher thickness at a given basis weight compared to a 100% Cellulose Comparative composition, when processed under similar conditions. The cellulose ester staple fibers can also provide the wet laid-sheet with a higher softness and/or higher water absorbance, compared to a 100% Cellulose Comparative composition, when processed under similar conditions.

  • Publication number: 20180223454
    Abstract: The biocomponent fiber functions as a carrier or vehicle for delivering additives to a polymer composition. The bicomponent fiber may be “splittable segmented pie” or “island-in-the-sea” construction with the sea being the low melt temperature component and the island being the high melt temperature component. The low melt temperature polymer may be selected from the group consisting of low density polyethylene (LDPE), high density polyethylene (HDPE), polylactic acid (PLA), polyhydroxyalkenoate (PHA), polypropylene (PP), polystyrene (PS), polyvinylidene fluoride, polybutylene succinate (PBS), low melt temperature polyethylene terephthalate, polytrimethylene terephthalate (PTT) and low melt temperature nylons.

  • Patent number: 9931490
    Abstract: A control system for an arterial catheter operable to selectively impede blood flow includes a processor and a storage medium accessible to the processor that bears instructions which when executed by the processor cause the processor to execute logic including receiving a first signal representing a physical parameter associated with a patient in whom the catheter is disposed, receiving a second signal representative of time, and causing inflation of a first balloon on the catheter to impede blood flow in the first artery. Based at least in part on the first signal satisfying a first condition, the instructions include causing deflation of the first balloon. Based at least in part on the second signal indicating elapse of a predetermined time period, the instructions include causing deflation of the first balloon regardless of whether the first signal satisfies the first condition.
