Definitions

  • the product comprises a warp-knitted material or a weft-knitted material including a plurality of pile loops on its surface, and a plurality of hooks made by cutting at least a part of the pile loops, thereby forming a material-engaging surface on the knitted material.
  • the present invention relates to a knitted product having a material-engaging surface, more particularly relates to a knitted material having a plurality of pile loops thereon at least a part of which are cut in the form of hooks so as to engage with another material having a roughened surface.
  • the principal object of the present invention is to provide a knitted product having a material-engaging surface which can be produced at high production speed and consequently, at low production cost.
  • the other object of the present invention is to provide a knitted product having a material-engaging surface provided with improved anchoring effect of loops and hooks due to interlocking with the basic knitted cloth of light weight.
  • Further object of the present invention is to provide a knitted product having a material-engaging surface of desireable elasticity and favourable flexibility suitable for a variety of uses.
  • FIG. 1 is a schematic plan view of a felt knitted cloth embodying the present invention having a plurality of pile loops thereon,
  • FIG. 2 is a schematic plan view of a warp knitted cloth embodying the present invention having a plurality of pile loops thereon,
  • FIGS. 3A, 3B, 4A and 4B are schematic side views of hooks of the present invention.
  • FIG. 5 is a perspective view of a hooking piece of a separable fastener embodying the present invention
  • FIG. 6 is a section taken along the line VI-VI in FIG. 5,
  • FIG. 7 is a perspective view of a hair curler embodying the present invention.
  • FIG. 8 is an enlarged sectional side view of a portion of the hair curler shown in FIG. 8.
  • FIG. 1 An example of the knitted cloth embodying the present invention having a plurality of pile loops thereon is shown in FIG. 1, wherein the pile yarns 1 are interlocked with the knitting yarns 2 at the positions 3 to form pile loops 4 over alternate wales of the weft knitted basic cloth of plain stitch consructed by the knitting yarns 2.
  • FIG. 2 Another example of the knitted cloth embodying the present invention having a plurality of pile loops thereon is shown in FIG. 2, wherein the pile yarns 5 are interlocked with the knitting yarns 6 at cotton laps 7 of the courses and silk laps 8 of adjacent courses to form pile loops 9 in such a way that the pile loops 9 float over three wales intervening in the respective laps of the warp knitted basic cloth constructed by the knitting yarns 6.
  • a knitted cloth having a plurality of pile loops as shown in FIGS. 1 and 2 can be used for a material-engaging surface such as a hooking element for a separable fastener, a hair curler and skid-proof tape by cutting at least a part of the pile loops on the basic knitted cloth.
  • Materials for making the knitted cloth of the present invention can favourably be chosed from materials in the form of filaments such as synthetic monofilaments, synthetic multifilaments, metallic wires, plastic wires, ordinary textile yarn and yarn made of glass fibers etc. Such materials in the form of filament will be called filamentlike material in the following description.
  • An embodiment of the present invention is obtained by using the different types of yarns made of filament-like materials described above as materials for pile yarns and basic yarns of the knitted cloth.
  • the knitted cloth is constructed by using thermoplastic monofilaments for the pile yarns and yarns made of thermoplastic synthetic fiber for the basic yarn, filament-like metallic yarn for the pile yarn and yarn made of thermoplastic synethetic fibers for the basic yarn, or thermoplastic monofilaments for the pile yarn and ordinary spun yarn of rayon staple for the basic yarn.
  • a practical method for satisfying the above-described requirement is constituted by permanently setting in an interlocked position the pile yarns 1 with the knitting yarns 2 in case of the embodiment shown in FIG. 1 or the pile yarns 5 with the knitting yarns 6 in case of the embodiment shown in FIG. 2 by using resin.
  • the knitted cloth is first coated by a thermoplastic resin in a liquid form and then heat-treated so as to bond the pile yarns firmly together with the basic knitting yarns by means of the hardened resin.
  • Another practical method for fixing the pile loops to the knitted basic cloth consists of using highly heatshrinkable synthetic fiber yarns as the knitting yarns forming the basic knitted cloth.
  • the knitted cloth of this type is heat-treated, the basic knotted cloth shows high shrinkage, consequently, the hooks produced by cutting the respective pile loops of the above-mentioned heattreated knitted cloth are stably fixed to the basic knitted cloth.
  • Each fixed pile loop produced by the above-mentioned method is cut at a suitable place by a conventional cutting method.
  • the strength of engagement of the materialengaging surface of the present invention can be appropriately adjusted by selecting the shape of loops and the length of cut portion of a hook as shown in FIGS. 3A, 3B, 4A and 4B.
  • the strength of engagement of a hook shown in FIGS. 3A and 3B is higher than that of a hook shown in FIGS. 4A and 43, while the strength of engagement of a hook shown in FIGS. 3A and 4A, wherein the length of cut-off portion is smaller, is higher than that of a hook shown in FIGS. 3B and 4B, wherein the length of cut portion is greater.
  • FIGS. and 6 A hooking element for a separable fastener embodying the knitted cloth of the present invention is shown in FIGS. and 6, wherein a plurality of hooks made of the above-mentioned filament-like materials are fixed firmly to the basic knitted cloth 11 by the above-mentioned method.
  • all the hooks are formed in the shape shown in FIG. 3B, it is also possible to choose another shape of hooks or to mix different shapes of hooks in accordance with the strength of engagement required in the end use.
  • FIGS. 7 and 8 an example of a hair curler embodying the knitted cloth of the present invention is shown, wherein a plurality of hooks 12 made of the above-mentioned filament-like materials are fixed to the basic knitted cloth 13 by the above-mentioned method.
  • the knitted cloth thus formed is attached to the base material 14 of the hair curler by a suitable bonding agent.
  • Knitted material having on one side a multiplicity of upstanding hook-like elements suitable for repeated face-to-face engagement and disengagement with a material having a multiplicity of upstanding pile loo-p elements, comprising a basic knitted fabric of filament-like material yarn, a plurality of hook-like elements knitted-in by a series of interconnecting and intermeshing loops which are interlocked with the filament-like material yarn of the basic knitted fabric resulting in said hooklike elements firmly anchored and fixed into the basic knitted fabric and said hook-like elements projecting away from a surface of the basic knitted fabric.
  • the knitted material according to claim 1 further including a bonding agent disposed on the basic knitted fabric to reinforce and stabilize said basic knitted fabric.
