    Abstract: A skin-contacting fabric underlay for use beneath a therapeutic or prosthetic device on a human or animal body part is formed as a tube of knitted fabric. The yarns forming the fabric have a core of elastic material surrounded by moisture-transporting filaments of substantially non-elastic material, the yarn having elasticity, the fabric having a warp-knitted structure characterized by an artificial terry surface on an inner skin-contacting surface of the tube. The artificial terry surface is formed by underlaps of the yarn, in which the elasticity of the yarn causes the underlaps to draw up and form artificial terry loops that contact the skin of the body part about which the tube is sleeved. The artificial terry loops serve to space overlaps of the yarn from the skin and to move moisture away from the skin.

  • Patent number: 8448309
    Abstract: The present invention relates to an aramid nonwoven fabric showing more improved tenacity and superior heat-insulating property, and a method of preparing the same. The aramid nonwoven fabric is what includes 10 to 100 wt % of para-aramid staple fibers and 0 to 90 wt % of meta-aramid staple fibers, and has an air permeability of 40 to 200 cm3/cm2/sec and an average pore size of 20 to 50 ?m. Such aramid nonwoven fabric can be prepared by carding aramid fibers including the para-aramid staple fibers and the meta-aramid staple fibers so as to form a web, needle-punching the same, and water-punching the same with a prescribed water pressure.

  • Patent number: 8420005
    Abstract: The present invention provides a meltblown wetlaid method for producing non-woven fabrics with anti-mildew, anti-bacteria and deodorizing capabilities from natural cellulose. The method comprises selecting wood pulp as raw material and using N-methylmorpholine N-oxide (NMMO) as dissolving solvent and 1,3-phenylene-bis 2-oxazoline (BOX) as stabilizer to form mixed cellulose mucilage as well as using modified and nano-miniaturized natural chitosan as additive for blending and dissolution to form cellulose dope. By meltblown method, the dope is extruded out of spinnerets to form filament bundle, then by ejecting mist aerosol of water, the filament bundle is coagulated with regeneration. After post treatments of water rinsing, hydro-entangled needle punching, drying, winding-up and the like having been orderly applied, then final product for nonwoven fabric of continuous filament with anti-mildew, anti-bacteria and deodorizing capabilities is produced.

  • Patent number: 8418330
    Abstract: The invention relates to a water bar comprising nozzle parts for a suction chamber to apply jets to fabrics, knitted fabric webs, or nonwoven fabrics copoosed of staple fibers, endless filaments, or cellulose fibers, also in several layers, or mixtures thereof, and a suction area which is located on the bottom side of the suction chamber and is used for sucking off spraying water. The aim of the invention is to largely prevent spraying water or spraying mist in the region of the water jet that is discharged from the water jet beam. Said aim is achieved by assigning an air supplying device to the water bar and/or the suction chamber, said air supplying device being provided with at least one outlet which is located in the region of the water bar and extends to the region of the nozzle ports of the water bar.

  • Patent number: 8381376
    Abstract: A method of manufacturing a fibrous structure is particularly, though not exclusively, applicable to the manufacture of friction products such as preform discs. The method comprises mounting a former on a shaft. First feeds of fibrous material are spaced along the shaft and applied to the former in a direction tangential to the shaft as the shaft is rotated. A second feed is also applied to the former in a direction substantially parallel to the longitudinal axis of the shaft. The fibrous materials in the feeds overlie as the shaft rotates and the thickness of the material applied to the former increases to form the fibrous structure. Lengths of the first and/or second feeds are then inserted into the fibrous structure body in a radial direction with respect to the shaft as the shaft is rotated to interconnect the overlying layers and hold the structure together.

  • Patent number: 8381375
    Abstract: A crosslapper receives a card web and folds it into a lap intended to be needle-punched or consolidated by other ways. The web includes zones which are more condensed, having a spectrum of orientation of fibers with a component parallel to the width of the web, alternating with less condensed zones having a longitudinal unidirectional spectrum of orientations. The zones which are less condensed are used to form the edge zones of the lap. The result is that the lap has different respective spectra of orientation which pre-compensate for the unwanted changes produced by the needle-punching or other consolidation which follows. A needle-punched lap is obtained having a uniform MD/CD ratio (relationship between longitudinal and respectively transverse tensile strengths) or having a sought profile of the MD/CD ratio across the width of the lap.
