Definitions

  • This invention relates to a stitched non-woven fabric adaptable for use as a blanket and other products and having markedly higher stability and strength, as compared with prior non-woven, needled fabrics, the high strength being sufiicient to eliminate the necessity of a supporting layer or scrim in the fabric.
  • non-woven fabric for use as blankets by needling -a batt of non-woven fibers with barbed needles without thread to interlace or interloop the fibers of the batt for producing a self-sustained non-woven fabric. While this method of manufacturing is less expensive and less time consuming than weaving, it is subject to the disadvantage that the needled non-woven fabric does not possess the desired stability and strength and resistance to shedding during .wearand laundering.
  • the blankets do not have the markedly high strength that characterizes the blankets of the present invention which do not require a scrim or support.
  • the superior non-woven fabric which does not require a scrim, may be produced by utilizing a self-sustaining batt of nonwoven fibers which preferably extend generally in the widthwise direction of the fabric to provide strength and stability to the fabric in the widthwise direction and elongated spaced-apart rows of stitches embedded in the batt of fibers and formed from separate continuous yarns extending in generally the lengthwise direction of the batt throughout the length thereof and passing from one face of the batt to the other face of the batt to interlock the fibers and to provide strength and stability to the fabric in the lengthwise direction.
  • the thus formed fabric also includes at least one outer treated surface on the batt comprising fibers so disposed as tocover substantially the rows of stitches in the batt and provide the desired finish on the fabric for use as blankets, bedspreads, outerwear, etc.
  • the self-sustaining batt is preferably a carded and cross lapped batt.
  • the batt may be needled before stitching or after stitching to enhance the stability and strength thereof with the number of needle penetrations being carefully controlled to avoid boardiness or the like.
  • the treated surface may comprise a napped surface on one or both sides of the fabric when the fabric is used as blankets, bedspreads or the like; or may include a calendered, brushed, sheared, etc. surface when utilized as garment material.
  • the spacing of the stitches and the type of stitch utilized is important for obtaining the superior strength and stability in the non-woven fabric.
  • the rows of stitches are spaced apart a distance less than the length of the fibers in the batt to effect interlocking of the fibers.
  • the fibers utilized in this non-woven fabric have an average staple length of from about one-half inch to about four inches and the spaces between the rows of stitches are preferably from about one-sixteenth inch to about one-eighth inch.
  • the preferred stitch construction for the non-woven fabric of this invention is one in which two sets of continuous yarns are utilized and each of the rows of stitches is formed from at least two continuous yarns and has stitch loop components on one side of the batt and interconnected diagonally extending and straight linestitch components on the other side of the batt and in which the stitch loop components are formed from both of the yarns and in which the diagonally extending stitch components are formed from one of the yarns and the straight line stitch components are formed from the other of the yarns.
  • This type of stitch construction insures the desired interlocking of the fibers within the batt and provides superior strength and stability to the fabric in both the lengthwise and the widthwise direction.
  • GRAB TENSILE TESTS [ASA Standards for woven household blanket fabrics are 25 lbs. Breaking strength in both the lengthwise and widthwise directions] Stitched Samples Needled Samples (Wlthout supporting layer) (with supporting layer) Breaking Strength in lbs. Breaking Strength in lbs.
  • the stitched samples Without a supporting layer therein were from about 200% to about 500% stronger and more stable than the needled samples with a supporting layer therein (constructed according to the Smith patents).
  • FIGURE 1 is an enlarged fragmentary perspective view of one side of the stitched fabric constructed according to this invention and having treated surfaces on one portion thereof and illustrating the stitch construction in the other portion thereof;
  • FIGURE 2 is an enlarged fragmentary perspective view of the other side of the stitched fabric of FIGURE 1 having treated surfaces on one portion thereof and illustrating the stitch construction on the other side in the other portion thereof;
  • FIGURE 3 is a somewhat schematic top plan view illustrating one example of how the stitched fabric may be constructed according to this invention
  • FIGURE 4 is a somewhat schematic side elevational view of the apparatus of FIGURE 3.
  • FIGURE 5 is a somewhat schematic side elevational view taken along the line 5-5 of FIGURE 3 and particularly illustrating the stitching instrumentalities utilized in this invention.
  • the stitched fabric 10 comprises a self-sustaining batt, generally indicated by the reference 11, of non-Woven fibers 12 extending generally in the widthwis-e direction of the fabric to provide strength and stability to the fabric in the widthwise direction.
  • the fabric 10 further comprises elongated spaced-apart rows of stitches 13 embedded in the batt of fibers and extending in generally the lengthwise direction of the batt throughout the length thereof and passing from one face of the batt to the other face of the batt to interlock the fibers and to provide strength and stability to the fabric in the lengthwise direction.
  • the rows 13 of stitches are preferably spaced apart a distance less than the length of the fibers in the batt to insure the desired interlocking of the fibers and to provide strength and stability to the batt.
  • Each of the rows of stitches 13 are formed fromtwo continuous yarns Y1 and Y2 and have stitch loop components 20 on one side of the batt 11 and interconnected straight line stitch components 21 and diagonally extending stitch components 22 on the other side of the batt 11.
  • the stitch loop components 20 are formed from both of the yarns Y1 and Y2 and the straight line stitch components are formed from one of the yarns Y1 only and the diagonally extending stitch components are formed from the other of the yarns Y2
  • the fibers 12 utilized for making up the batt 11 may be any suitable natural or synthetic fibers including viscose or acrylic or other textile fibers or blends thereof with wool, nylon and polypropylene.
  • the yarns Y1 and Y2 utilized to form the rows of stitches 13 may be of various natural or synthetic fibers or blends but continuous filament synthetic yarns are advantageous to obtain relatively high strength and to prevent breakage in the manufacturing operation and to also give good tensile strength to the finished fabric.
  • the stitched non-woven fabric 10 also includes at least one outer treated surface on the batt comprising fibers so disposed as to substantially cover the rows of stitches in the batt and provide the desired finish on the fabric.
  • the stitched batt 11 includes outer napped surfaces 25 of napped fibers which have been napped to a sufiicient height and density to cover the rows of stitches in the fabric and provide uniform outer faces on the fabric to adapt the fabric for use as blankets or the like.
  • these outer treated surfaces may comprise other types of mechanical treatment other than napping, as pointed out above.
  • FIGURES l and 2 only a portion of the fabric has been napped to illustrate the rows of stitches; however, it is to be understood that the entire faces of the blanket fabric would be napped.
  • FIGURES 3-5 a suitable apparatus is illustrated for forming the stitched non-woven fabric 10 of FIGURES 1 and 2; however, it is to be understood that this apparatus is only illustrative and forms no part of this invention and that other suitable apparatus might also be used.
  • a conventional opening and feeding device feeds the bulk fibers 12 in staple form to a card, Garnett, or other suitable fiber opening device, broadly indicated at 32, to form a batt of fibers 12 extending generally lengthwise of the batt.
  • the batt of fibers 12 from the card 32 fed to a cross-lapping device 33.
  • the cross-lapping device 33 operates back and forth across a conveyor 36 to deposit the batt of fibers 12 thereon.
  • the cross-lapping device 33 is preferably operated at a sufiicient speed, relative to the speed of the conveyor 36, so that the fibers 12 are deposited onto the conveyor 26 to form another batt 11 having the fibers 12 extending generally widthwise thereof to provide strength and stability in the fabric in the widthwise direction.
  • the cross-lapped batt 11 conveyed from the cross-lapping device 33 to another conveyor 37 which moves the batt 11 into a stitch forming mechanism, illustrated somewhat schematically at 40, to form lengthwise extending rows,
  • the stitch forming mechanism 30 is of the type utilizing two beams 41 and 42 for supplying two sets of continuous yarns Y1 and Y2 to the stitch forming instrumentalities for forming stitch constructions utilizing two sets of yarns therein.
  • the stitch forming mechanism 30 may be of the type having a bank of side-by-side stitching needles which are adapted to pass through the batt and form individual lengthwise extending rows of stitches with the above described stitch components.
  • the stitched batt is led from the stitch forming mechanism 40 by a conveyor 43 to a treating mechanism, broadly indicated at 44.
  • This treating mechanism 44 may be a napping mechanism or, as set forth above, a calendering, brushing, shearing, etc, mechanism, depending upon the desired finish to be placed on the fabric.
  • the napped surfaces 25 would be formed on each face of the fabric of sufficient density to cover the rows of stitches 13 in the fabric 10, as may be seen in FIGURES 1 and 2.
  • the napped fabric 10 may then be wound on suitable apparatus, generally indicated in the drawings at 45.
  • a stitched non-woven fabric has been produced which is adaptable for use as blankets and other products and which has markably higher stability and strength, as compared with prior non-woven, needled fabrics, the higher strength being sufficient to eliminate the necessity of a supporting layer or scrim in the fabric.
  • a stitched non-woven fabric adaptable for use as a blanket said fabric being constructed to eliminate the necessity for the use of a supporting layer or scrim therein by providing marked increased strength and stability as compared with prior non-woven, needled fabrics, said fabric comprising:
