Abstract: The present invention pertains to a method to manufacture a textile product comprising a first sheet having a width and a length, and polymer yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polymer yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, transporting the sheet in a direction parallel to its length along a heating element, the heating element being directed to the second surface of the sheet, heating the second surface with the heating element to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the method comprises transporting the sheet in contact with the heating element, wherein the heating element is a stationary rigid plate-like element having a width corresponding to the width of the sheet, and a length that extends parallel to the length of the sheet, the plate being curved in its length direction, wherein the outer c

Abstract: Unique blends of fibers that incorporate synthetic cellulosic fibers to render fabrics made with such blends more durable than fabrics made with natural cellulosic fibers such as cotton. While more durable than cotton, the synthetic cellulosic fibers used in the blends are still inexpensive and comfortable to the wearer. Thus, the benefits of cotton (affordability and comfort) are still attained while a drawback of cotton—low durability—is avoided. In one embodiment, the fiber blend includes FR modacrylic fibers and synthetic cellulosic fibers, preferably, but not necessarily non-FR lyocell fibers such as TENCEL™ and TENCEL A100™. Other fibers may be added to the blend, including, but not limited to, additional types of inherently FR fibers, anti-static fibers, anti-microbial fibers, stretch fibers, and/or high tenacity fibers. The fiber blends disclosed herein may be used to form various types of FR fabrics.
Abstract: A method of statically testing dependence in a dataflow program is provided, the method comprising receiving a dataflow program which provides parameters, including consumption rates, production rates on connections between actors in the program and a number of initial samples (delays) on the connections, generating from the parameters a model of a precedence graph for the dataflow program representing dependence constraints between distinct firings of the number of actors. For the model, determining a feedback distance between multiple firings of a same actor, determining sets of parallel regions comprising a given number of actor firings of a same actor, composing mutually independent component regions comprising at least a part of the sets of parallel regions, and composing one or more composite regions comprising one or more component regions and/or one or more sets of parallel regions, being composed so that a pre-determined criteria is satisfied.

Abstract: A thermoplastic cellulose derivative composition of the present invention contains, as a main component, a cellulose ester having an aliphatic polyester side chain having a repeat unit having 2 to 5 carbon atoms, wherein a rate of heating loss at 200° C. is 5 wt % or less, a melt viscosity at 200° C. and 1000 sec?1 is 50 to 300 Pa·sec, and a melt tension at the time of take-up at 200° C. and 100 m/min is 0.1 to 40 mN. The present invention can provide excellent fiber products by melt spinning of the composition.
Abstract: A novel olefin textile fabric knitted woven and non-woven that in one aspect of the invention is disperse dyed to a light, medium or deep solid shade. In another aspect, the textile fabrics of the present invention are manufactured using olefin yarns that contain variable amounts of dye acceptor additives. A fabric with more than one tone of a color is dyed in a single dye bath. The fabrics and yarn using this invention can be processed using conventional spinning, weaving, knitting, web forming machines and will dye using existing dyeing and finishing systems. This invention is of particular value in the apparel and home furnishings industry.
Abstract: The present invention provides a durable to a wicking aramid fabric formed from crystallized aramid yarns or mixtures of aramid and other yarns for use in firefighter turnout gear and other protective apparel and a process for making this durable wicking fabric.
