Abstract: A chemical fiber knitted towelling making method which is to brush the pile yarn of the fabric and remove impurities from the pile yarn after the steps of knitting, dyeing and napping, and then to cut the pile yarn to a uniform length after brushing, and then to steam damp the fabric and to dry the damped fabric by steam heat, and then to set the well-treated fabric in shape, and therefore the pile yarn of the fabric does not twist into rings and will not deform as a result of washing with water.

Abstract: An improved method of making (100% heat-resisting) chemical or synthetic fiber knitted towelling which includes a step of primary shearing to cut the pile yarn of a knitted fabric, obtained after napping of the fabric; a step of brushing the knitted fabric, after the step of primary shearing by means of the application of two reversed card-wire raising fillets, permitting the knitted fabric to be fed at a speed of 3-4 meters per minute; a step of steam damping at about 100.degree. C. and a step of steam heat drying respectively performed in a dryer; the above steps taking place before the fabric is shaped by a step of setting of the knitted fabric in a heat-setting oven. Further shearing of the pile yarn is employed when needed.

Abstract: Light-trapping members are cut out of a ribbon consisting of a base fabric and piles. The piles of the ribbon are pressed against the peripheral surface of a thermal drum to be inclined in the width direction after the ribbon is passed through and twisted by a twister disposed close to the thermal drum. The light-trapping members with inclined piles are attached to a film passage mouth of a self-advancing-type photographic film cassette with the inclination of the piles directed to the outside of the film passage mouth, so that the leading end of a photographic film can be advanced smoothly by rotation of a spool through the light-trapping members to the outside of the cassette.

Abstract: The present invention relates to improvements in puncture-resistant and medicinal treatment garments. Garments made from fibers such as KEVLAR.RTM. and designed to deter penetration of objects are subjected to an additional brushing step to enhance the fibers' abilities to prevent penetration of sharp needle-like penetrating objects. The fibers may also be coated with an abrasive material to further engage and deflect penetrating objects. In another aspect of the invention, the fibers may be coated with a disinfectant or pharmaceutical agent. The coated fibers, having the improved fiber structure resulting from the brushing step, may be used in fabrics to treat skin conditions, disinfect penetrating objects in puncture-resistant materials, or as a disinfecting prevention fabric for use in textiles in high risk infection areas such as hospitals and public facilities.

Abstract: Filament yarns composed of multicomponent fibers of the matrix/segment type are produced and processed into textile fabrics by false-twist texturing the multicomponent fibres made up of segments of varying deniers to cause softening the matrix to bond the filaments together over short, medium or longer sections of the yarn. After conversion of the yarns into fabrics, the fabrics are subjected to a shrinking treatment. The fabrics so treated have a reduced tendency to crease or wrinkle, better crease recovery and better dyeing properties. The denier of the lower denier segments should be finer than 0.6 dtex and the denier of the high denier segments should be at least 1 dtex; the weight ratio of low to high denier segments in the yarn ranges from about 25:75 to about 75:25. The matrix is preferably made of polyamide 6 while the segments are polyethylene terephthalate. The cross-sectional shapes of the fibers may e.g.

Folding is performed by rollers with blades which enter and move along the length of the grooves. The rollers are guided precisely by guide members on their opposite axial sides. To prevent the rollers from pushing the textile material across the grooved cylinder surface, the rollers are rotated independently of their contact with the web.

Abstract: A knitted velour lace fabric is made by knitting a net or mesh ground fabric and knitting velour threads on to the ground fabric. Each velour thread substantially follows the path of one of the ground threads, except that at points along the length of the velour thread the latter is extended across a plurality of wales of the ground fabric to form an elongated loop. Stitches of soluble yarn are knitted on to the ground fabric to temporarily hold the elongated loops against one face of the ground fabric. Thereafter, the fabric is treated with a liquid or vapor to dissolve the soluble yarn and permit the velour loops to project outwardly from the face of the ground fabric. The velour loops may be of different lengths.

The novel tubular knitted high pile fabric is specially formed with the pile omitted at walewise spaced courses thereof to form walewise spaced bands of non-pile fabric, and the seam is then formed in the non-pile fabric.

Abstract: A method for increasing the depth of a tack-spun thermoplastic pile on a backing layer comprises space heating the pile side of the product for a time and temperature less than that at which the pile collapses, said temperature being between the glass rubber transition temperature but above ambient and the temperature at which the pile collapses, using a heat source not in contact with the pile, and subsequently cooling the pile to ambient temperature.

Abstract: A woven fabric made from flat warp and weft tapes of polypropylene, such as is currently used as a primary carpet backing, is subjected to a repeated needling operation which breaks down each warp and weft component into a multiplicity of fibrils. This fibrillation of the warp and weft in the woven fabric produces a marked change in the surface of the fabric from a relatively shiny to a relatively matt finish. The fibrillated fabric may be rendered dyeable to a good coloration (similar to the color of dyed face yarns of a carpet) either by including a dyeable material in with the polypropylene from which the tapes are originally formed, or by adhering a dyeable coating to the fibrillated fabric. Further repetition of the needling operation reduces the denier of the fibrils still more and produces a generally softer fabric.

A yarn having a thickness in a range between 30 and 300 denier, the thickness of most of individual filaments or fibers thereof being in a range between 1.0 and 8.0 denier, is utilized as the warp; while a spun yarn having a thickness represented by a total denier in a range between 50 and 1000 denier, the thickness of the most of individual component fibers thereof being in a range between 0.0001 and 0.4 denier, is utilized as a first weft, and a yarn having a fineness represented by a total denier in a range between 30 and 300 denier, the thickness of the most of individual filaments or fibers thereof being in a range between 1.0 and 8.0 denier, is utilized as a second weft. At least one of the warp and the second weft does not substantially involve crimped filaments or fibers. A combination woven fabric structure provided with a number of floating points of the first weft upon the warp in a range between three and seven is adopted.

Abstract: A knitted velour fabric is made by knitting a ground fabric and knitting velour threads on to the ground fabric.
