Definitions

  • the present invention relates to a two-layer, heat-sealable nonwoven having the features of the preamble of claim 1.
  • US-A 4,490,427 describes an inherently stable heat-sealing tape, built up from a parallel group of thermoplastic softenable threads, which are thematically connected to one another via tangled thermoplastic fibers.
  • Polymer fibers made from materials which have a melting point below 150 ° C., such as co-, ter- or higher polymers of polyamides or polyesters, for example a terpolymer made of nylon 6, nylon 66 and nylon 12, are preferably used.
  • the tensile strength of this product is not achievable sufficient in all applications, as the following comparison of staple fibers (source: E. Wagner, Die textile Rohstoffe, DFV Frankfurt (Main), (1981)) with the above-mentioned thermoplastic fibers (own measurements) shows: The low values of the latter fibers are due to the low crystallinity or low orientation towards stretching.
  • US Pat. No. 4,440,819 specifies a fiber arrangement in which unidirectionally directed, high-tensile high-modulus fibers, preferably mineral fibers, are melt-bonded to one another by means of polymeric tangled fibers.
  • this layer can be impregnated with resin and laminated to form a multi-layer laminate. It has been shown, however, that such laminates lack the required longitudinal elongation capacity, particularly in the case of grammages above 40 g / m 2.
  • GB-B 1,117,751 describes the production of a heat-sealable stiffening material, thermoplastic fibers preferably being extruded onto a continuously moving nonwoven carrier and being fused to one another and to the carrier.
  • the carrier consists of silicone paper that can be removed from the fiber mat.
  • This problem is solved, starting from the prior art shown in GB-B 1,117,751, in a nonwoven fabric with the characterizing features of claim 1.
  • the subclaims indicate preferred embodiments.
  • the first layer of the nonwoven fabric according to the invention can consist of randomly arranged thermoplastic polymer filaments or of parallel thermoplastic polymer filaments, the latter being melt-bonded to one another by randomly deposited thermoplastic filaments, as indicated in the aforementioned US Pat. No. 4,490,427.
  • the fibers of the second, heat-sealable layer can be solidified with one another as desired. B. by application of heat and / or pressure, by polymeric binder dispersions or by combinations of the types of consolidation mentioned.
  • suitable fiber materials are the known in the case of single-layer, iron-on nonwovens (US Pat. No. 4,490,427) co-, ter- or higher polyesters, such polyamides or polyvinyl chloride, such as, for. B. a terpolymer of nylon 6, nylon 66 and nylon 12.
  • the melting point of these fibers according to the invention must be in the range of 75 to 140 ° C and lower than that of the non-binding fibers.
  • thermoplastic, bindable fibers and filaments in the entire nonwoven composite must be between 40 and 98% by weight.
  • the weight per unit area of the second heat-sealable nonwoven layer preferably makes up 5 to 60% of that of the overall composite.
  • the heat-sealable second nonwoven layer has irregularly distributed openings of 0.5 to 5 mm in width and 1 to 50 mm in length with a width / length ratio of 1:20 to 1: 100.
  • the spacing of the openings from one another can be varied over a wide range down to fiber thickness dimensions, as can the size of the openings.
  • This advantageous embodiment allows heat and pressure to act on the nonwoven fabric so that it can penetrate on all sides with the heat-sealable components; the composite thus behaves like a single-layer, heat-sealable nonwoven.
  • the manufacturing process for the nonwoven fabric according to the invention is advantageously carried out analogously to the extrusion or meltblowing process described at the beginning, described in GB-B 1,117,751, the first nonwoven fabric layer forming the continuously moving textile backing on which the second heat-sealable fiber layer is permanently fixed.
  • the heat-sealable composite according to the invention has a surprisingly improved tensile strength, good adhesion to outer materials, such as. As cotton / polyester, polyester, nylon or cotton, and easier to manufacture, without the need for an intermediate support layer. These improved properties extend the field of application of such a nonwoven composite to those cases where high tensile strengths are absolutely necessary and where the previous heat-sealable nonwovens had to fail.
  • the figure attached is the photographic top view of the second layer of the nonwoven according to the invention, the scale is 1: 0.97.
  • a 12 g / m2 nonwoven was made by carding a mixture of 30% by weight thermally adhesive copolyester fibers (3.5 den at 38 mm stack length, melting point at 130 ° C.) and 70% by weight polyethylene terephthalate staple fibers (3.0 manufactured at 50 mm stack length). The fibers were bonded using a commercially available polymer binder dispersion based on polyester. It was then dried with a set of multiple steam-heated drying cylinders at a closing pressure of 1.41 to 2.11 kp / cm2 (20 to 30 psi).
  • the dry weight of the added binder was 4 g / m2 with a total weight of 16 g / m2.
  • the fiber: binder ratio in the nonwoven fabric was 75:25, its density was 0.039 g / cm3.
  • the nonwoven fabric from Example 1A was provided with a heat-sealable fiber sheet made of copolyester filaments and had a weight of 50 g / m2.
  • the copolyester filaments had a softening range of 130 to 135 ° C.
  • a composite was created by the combined application of heat and pressure using calender rolls. The temperature was 85 ° C, the closing pressure was 1.41 kp / cm2 (20 psi).
  • a 17 g / m2 nonwoven fabric was produced as in Example 1A and, in addition to the polyethylene terephthalate fibers, contained 30% by weight of thermally adhesive copolymer fibers (melting range around 130 ° C.).
  • the total weight of the binder-bound nonwoven was 22 g / m2.
  • a 14 g / m2 nonwoven fabric was made as in Example 1A but with a fiber blend ratio of 1: 1. After finishing with binder, the total weight of the nonwoven fabric (dry) was 18 g / m2.
  • Example 3A The nonwoven fabric from Example 3A was laminated with the heat-sealable fibrous sheet material analogously to Example 1B, but its weight was 80 g / m2, its melting range was 110 to 115 ° C. and the calendering temperature was 70 ° C.
  • the nonwoven fabric from Example 4 A was laminated with a heat-sealable fiber sheet. This had a weight of 50 g / m2 and contained a terpolyamide made of nylon 6, 66 and 12 with a melting range of 110 to 120 ° C.
  • Lamination to a composite was carried out using a calender roll heated to 70 ° C. at a closing pressure of 1.41 kp / cm2 (20 psi).
