Definitions

• the present invention relates to circular knitted or knitted round, polyurethane-coated, elastic webs of synthetic filament yarn, in particular of polyester, and to articles of clothing made therefrom.
• Such elastic, polyurethane-coated interlock circular knitted fabrics made of polyester are z. B. from FR-OS 22 16 111 be ⁇ known. Because of the elasticity of the knitted fabric, they are elastic, largely unsuitable for many applications owing to their high degree of deformation, and in particular are not sufficient for items of clothing which are worn directly on the body and which are also firmly attached to the skin during movements.
• polyurethane-coated circular knitted or circular knitted fabrics made of synthetic yarn, in particular polyester filament yarn have a particularly low workmanship when the circular knitted or circular knitted fabrics are made of textured, continuous filament yarn and are provided with a polysiloxane elastomer finish , so that the deformation work compared to non-equipped goods is reduced in a ratio of 1: 1.1 to 1: 5, in particular 1: 1.5 to 1: 3.5, in stretch ranges up to 70% of the elongation at break with one
• the yarns can be made from the same or different fiber materials, it being possible to use both untwisted and twisted or folded endless filaments.
• the yarns can be pure white, matted, dyed or spin-dyed.
• the circular knitted or circular knitted fabric can also be treated according to the dyeing or printing processes customary in the textile industry.
• Interlock circular knitwear is particularly suitable as a material web.
• circular terry or circular knitted fabrics have proven to be suitable.
• other yarns can be used for the terry handles, e.g. B. Cotton yarns.
• a method is known as polysiloxane elastomer equipment in which organopolysiloxanes, including alkyl, phenyl,
• Dialkylpolysiloxanes and hydroxyl- and alkylhydrosiloxanes, here especially polymethylhydrogensiloxanes, are applied in aqueous emulsion or preferably in perchlorethylene to the fibers of the knitted or knitted fabric and crosslinked there. Together with the use of textured yarns, this finish gives the knitted or knitted fabric a very high degree of elasticity, such as. B. in DE-OS 17 94 170 and JP-OS 72 23 717 be described. The elasticity is not reduced by the polyurethane coating. Furthermore, in contrast to the non-coated product, the polyurethane-coated product surprisingly results in a significant reduction in the work of deformation.
• the silicone elastomer finish can be applied on both sides, but preferably only on the side that is not to be coated with polyurethane.
• the coating with polyurethane can be carried out in the usual way by applying the prepolymer onto the circular knitted or circular knitted fabric and subsequent further condensation.
• the application of the polyurethane layer in the reverse process has proven itself.
• Commercially available mixtures based on hydroxyl polyesters, polyethers or polyhydroxyl polyester urethane and polyisocyanates can be used as the prepolymer.
• the polyurethane can be or are colored in the usual way, even with fluorescent dyes; it can also be colorless and reveal the color of the circular knitted or circular knitted fabric underneath.
• the polyurethane coating can also be grained in the usual way.
• the elastic, polyurethane-coated circular knitted or circular knitted fabric is z. B. produced by the following procedural steps:
• An interlock circular knit fabric of approx. 130 g / m 2 was produced using a textured polyester filament yarn dtex 76 f 35.
• a ⁇ to 80 cm WS) water-impermeable fabric web was obtained which had a water vapor permeability of 200 g / m 2 ⁇ measured in 24 hours according to DIN 53 122) .
• Parts of both the uncoated and the coated web were finished with polysiloxane.
• the elastic behavior of the web according to the invention was carried out on the basis of DIN 53 835 Part 3 "Testing the reliable behavior of yarns and twists between constant tensile strengths with a single load", since there is no DIN standard for circular knitted or circular knitted fabrics.
• the test was carried out on samples which had a width of 90 mm and were subjected to a deformation rate of 500 mm / min in the two clamps with a clamping length of 200 mm and a preload force of 300 cN.
• the upper yield strength was set to 40% elongation in the longitudinal direction and 75% elongation in the transverse direction.
• the knitted fabrics with and without polyurethane coating were Weil compared with and without polysiloxane elastomer equipment in terms of tensile force at a given elongation in the longitudinal or transverse direction.
• the sample width, clamping length, prestressing force and deformation speed were chosen as in the determination of the permissible behavior.
• FIGS. 1 and 2 show the force-strain
• OMPI diagram in the longitudinal direction of the fabric Fig. 2 and 4 in the transverse direction.
• the curves with the designation a) are the connections of the found values for the surface image without polysiloxane elastomer finish, with b) the curves with polysiloxane elastomer finish.
• FIGS. 1 and 2 show that, in the case of the web not coated with polyurethane, the silicone elastomer finish causes practically no change in the deformation forces or work, while in the case of the polyurethane-coated web the effect according to the invention Reduction of the deformation forces or the deformation work occurs.
• Sports clothing such as tracksuits, tobogganing and ski clothing, as well as clothing suitable for water sports, such as windsurfing, sailing and canoeing, can be produced from the webs according to the present invention.
• the clothing can advantageously consist of the webs of the invention.
• the nit polyurethane-coated webs are suitable for fashionable clothing such as raincoats and disco-look suits.
• the circular knitted fabric according to the invention is shown in the further drawing, specifically in FIG. 5 as smooth circular knitted fabric and in FIG. 6 as terry goods.
