  • the molten fiber constituted by a plurality of spun yarns and the multifilament is formed into a monofilament shape constituted by a plurality of fibers 2a which are not molten and left, and the molten resin 2b integrally including them, according to the heating treatment 12 in Fig. 1 , and the molten low-melting-point portion is fusion bonded to the surfaces of the glass yarn and the stainless thin line.
  • the winding yarn is a multifilament. Numerical value in parentheses of each of fields about the glass yarn, the molten fiber and the winding yarn corresponds to numerical value indicating a wire diameter on the assumption that a total cross sectional area of the fibers is one fiber.
  • the tough yarns of the product numbers 3 and 6 and the product numbers 9 and 10 indicating the kind of the winding yarn in Table 1 are particularly excellent as the ground yarn which is used for knitting the cutting resistance glove according to the plating.
  • the core yarn using the stainless single yarn (monofilament) as the hard fiber 1 can not often coat the hard fiber 1 sufficiently due to generation of slip in a longitudinal direction of the yarn between the stainless and the molten resin.
  • This problem can be solved by employing two molten fibers 2m and 2n as the molten fiber 2 and compounding them, as shown in Fig. 3 .

  • Table 2 is a table showing the contents of the test which the inventors made about the core yarn 20b shown in Fig. 3 . More specifically, the test is made by winding the molten fiber 2m to the hard fiber 1, thereafter winding the molten fiber 2n so as to intersect the molten fiber 2m forming the lower layer and compounding, and thereafter melting both the molten fibers 2m and 2n by applying the heating treatment 12. As a result of the test, it is confirmed that the problem mentioned above when using the monofilament stainless fiber can be solved.
  • the hard fiber, the molten fibers 2m and 2n and the winding yarn in Table 2 are described collectively in relation to a plurality of trial yarns having different twisting numbers, and the kinds of the fibers and the yarns described in plural lines in each of the fields indicate the manufacture by way of trial in relation to plural thickness sectioned by ",” in each of the fields.

  • the molten fiber is molten at least in a peripheral edge portion of each of the fibers according to the heating treatment 12, and is fusion bonded to the surfaces of the hard fiber and the woolly ester fiber in the lower layer, and a plurality fibers are solidified after being molten and are formed into a monofilament shape constituted by the molten resin 2b (refer to Figs. 7 , 12 and 16 ).
  • the core yarn using one stainless monofilament as the hard fiber can not often coat the hard fiber 1 sufficiently due to the weak fusion bonding force between the hard fiber and the molten fiber, and the flexibility of the knitted and woven fabric using the core yarn is not sufficient.
  • the hard fiber 1 is constructed by a twisted yarn of the glass fiber 1m and the stainless fiber 1n as shown in Table 4 and Fig. 11
  • the lower layer fiber 3 is constructed by two lower layer fibers 3m and 3n having reverse winding directions as shown in Table 5 and Fig. 15 , it is possible to enhance the flexibility of the core yarn or the tough yarn including the stainless monofilament which is excellent in the cutting resistance.
  • the embodiment shown in Table 4 is preferable in the case of attaching importance to the cutting resistance, and the flexibility can be also applied by employing the structure in which the stainless fiber 1n is wound to the multifilament 1m of the glass fiber.
  • the embodiment shown in Table 5 can be employed.
