Definitions
- the invention relates to the use of a nonwoven fabric for producing a chuck, in particular a chuck for reinforcing the upper parts of shoes.
- the invention further relates to a whale feed material, the one
- Milling is the deformation of materials by mechanical processing, especially by pressing and / or pulling.
- Walken is used in the shoe industry to thermally deform leather or textile surface materials.
- the goal here is a two-dimensional one
- a whale lining is a reinforcement layer that lies between the upper and the lining material in shoes.
- a prerequisite for the use as whale feed is that the materials used have good elasticity and permanent stretch, as these are suitable for the
- the thickness of the Meat lining is expediently adapted to the structural strength of the upper material. In practice, thicknesses in the range of 0.7 to 1.7 mm are generally used.
- a whale feed material is to be understood as materials that are designed for the production of a whale feed.
- whale lining as a reinforcing agent for the shaft parts, for example for the blade area, has long been known in shoe manufacture.
- a knitted material is often used as material for the whale lining
- Cotton material used The required high extensibility is inherent in the knitted materials due to their flexible knitted structure. Using the one to be glued to the underside of the upper
- the lining is given the necessary material for the subsequent flexing and pulling of the entire shaft onto the lasts, as well as deformability and deformability.
- knitted cotton materials offer at least for some reasons
- knitted wool-based feed materials generally have a relatively high basis weight of over 200 g / m 2 .
- the high weight per unit area is required to ensure sufficient dimensional stability, but it is disadvantageous because it increases the weight of the shoe and the soft material character is lost.
- Knitted fabrics are comparatively expensive and have almost none
- the object of the present invention is therefore to provide a material of the type mentioned at the outset, which is suitable for producing a chuck and by means of which the abovementioned disadvantages can be at least partially eliminated.
- consolidated nonwoven fabric comprising staple fibers with a staple length in the range from 25 to 75 mm, at least 15% by weight of the staple fibers being synthetic fibers, in particular polyolefin, polyester and / or polyamide fibers, for producing a chuck, in particular a chuck to reinforce the Upper parts of shoes.
- Nonwovens comprising staple fibers with a staple length in the range from 25 to 65 mm, 15% by weight of the staple fibers being synthetic fibers, in particular polyolefin, polyester and / or polyamide fibers, are outstandingly suitable for producing a chuck. So show these nonwovens
- the module values of the nonwoven according to the invention are 10%
- Elongation measured according to DIN ISO 9073-3, preferably at most 150 N / 5cm, for example from 10N / 5cm to 150N / 5cm, more preferably less than 100 N / 5cm, for example from 10N / 5cm to 100N / 5cm, more preferably less than 70 N / 5cm, for example from 10N / 5cm to 70N / 5cm.
- the static elongation of the nonwoven according to the invention measured according to DIN EN ISO 15977: 2011-05 (measuring distance 100 mm, load 50N, load time 10 minutes), is preferably more than 15%, more preferably more than 17% and in particular more than 20% .
- the permanent elongation of the nonwoven measured according to DIN EN ISO 15977: 2011 - 05 (measuring distance 100 mm, load 50N, load time 10 minutes,
- Recovery time 10 minutes preferably more than 10%, more preferably more than 12% and in particular more than 17%.
- the difference between static and permanent elongation of the nonwoven fabric at 10% elongation is preferably less than 30%
- 1% to 30% for example 1% to 30%, more preferably less than 15%, for example 1% to 15%, and in particular less than 7%, in particular 1% to 7%.
- Synthetic fibers in particular polyolefin, polyester and / or polyamide fibers of a certain stack length can be attributed.

- Nonwoven fabric according to the invention requires fewer flexing processes in order to achieve the desired flexing curve course - which manifests itself in significant cost savings. This was surprising for the person skilled in the art, because he would have expected that nonwovens would have a significantly poorer extensibility and permanent elongation than knitted fabrics. Nonwovens have namely
- nonwoven fabric used according to the invention has significantly better cut edge strength than knitted fabrics.
- nonwoven fabric according to the invention for the production of a whale lining is to be understood to mean that the nonwoven fabric is connected to a suitable upper material, for example a leather and / or synthetic material, and then subjected to shaping in a milling process.
- the nonwoven fabric is connected to the side of the upper material facing away from the visible side.
- the nonwoven is connected to a synthetic material as the upper material, which has no further backing layer on the side facing the nonwoven.
- the nonwoven fabric and the synthetic material are therefore directly connected to one another, for example by means of an adhesive or / or a direct coating. This is compared to using a two-layer synthetic material advantageous because a punching process is less required when preparing the chuck material for the churning process. In addition, there is no need for the adhesive between the nonwoven and the upper.
- the level of extensibility and permanent elongation of the nonwoven can be adjusted by the proportion of the synthetic fibers, in particular the polyolefin, polyester and / or polyamide fibers, and by the suitable choice of the parameters for the mechanical strengthening.

- mechanical strengthening is understood in the sense customary in the field of textile materials.
- the advantage of mechanical solidification is that compared to thermal and chemical

According to the invention, there is therefore preferably no thermal and / or chemical solidification in addition to the mechanical solidification.
- the nonwoven has a directional independence of the elongation, determined as the difference between the largest and smallest module value measured according to DIN ISO 9073-3 (measurement conditions: elongation of 3%, 5% or 10%, angle to the machine direction of 30 °, 60 °, 90 °, 120 °, 150 °, 180 °, 210 °, 240 °, 270 °, 300 °, 330 °, 360 °) of at most 30 N / 5cm, more preferably of at most 20N / 5cm, even more preferably of at most 15N / 5cm, in particular of at most 10N / 5cm.

- the fiber web can then be mechanically, for example by means of rollers, in
- MD Machine Direction
- thermoplastic fibers are used according to the invention.
- the synthetic fibers are preferably thermoplastic fibers.
- thermoplastic fibers are that they can be shrunk in a controlled manner by heat treatment of the nonwoven. This allows the fibers to be crimped and hooked together. This enables the nonwoven fabric to be stretched by at least the shrunk dimension during the flexing process. This means that the interlocking can be released again by mechanical stretching, which improves the stretchability of the nonwoven fabric.
- Polyolefin fibers with a crimp measured as the number of sheets according to DIN 53840 part 1, of at least 5 sheets / cm, for example from 5 to 15 sheets / cm and / or polyamide fibers with a crimp of at least 10 sheets / cm, for example 10 to 20, are particularly preferred Sheets / cm, and / or Polyester fibers with a crimp of at least 4 sheets / cm,

- the nonwoven fabric can also contain further thermoplastic staple fibers, preferably with a staple length of 25 mm to 65 mm, such as polyacrylic fibers.
- the proportion of the further thermoplastic fibers is preferably 10 to 75% by weight, more preferably 20 to 60% by weight, in particular 30 to 50% by weight, in each case based on the total amount of fibers in the nonwoven fabric.
