Definitions
- the stretching is preferably carried out in one direction only. Stretching in several directions, e.g. two or three directions is used when essentially the same tensile strength is to be achieved in several directions along the fiber plane. The stretching takes place over a heated brake shoe.
- the present invention is based on the object of equalizing the tensile strengths of such spunbonded fabrics in mutually perpendicular directions, the lower tensile strength being increased considerably in one of the two directions, but without the threads themselves being stretched and the thread titer becoming uneven.
- This object is achieved in that the nonwoven is needled prior to stretching and the stretching is carried out in the direction of the lower tensile strength by 20 to 200% of the relevant original dimension, while in the perpendicular direction the dimension is either retained or previously or simultaneously in the area is changed from ⁇ 10% of the original dimension.
- the drawing is carried out in a known manner at a temperature of 85 to 25 ° C. below the crystalline melting point of the thread material.
- the choice of the degree of stretching within the range according to the invention depends on the values that are to be achieved. Do you want e.g. the tensile strength in the weaker direction e.g. to increase by 15-20% without wanting to lose longitudinal strength, it is advisable to choose a slight stretch of 20-30%. The higher the degree of stretching in the weak direction is chosen, the more the tensile strength in the stronger direction is reduced, so that e.g. with stretching of 60-100% with regard to tear strength, approximately isotropic nonwovens are obtained, the tensile strength of which lies in the middle range between the original longitudinal and transverse strength. Since the lowest tear strength is decisive for the intended use, the nonwoven can be exposed to a greater load than the starting nonwoven after the treatment according to the invention.
- the method according to the invention is applicable to continuous filament nonwovens made of all thermoplastic materials such as polyamide, polyester, polyolefin. Nonwovens made from propylene homo- and copolymers and polyester are particularly preferred.
- the method according to the invention is to be explained in more detail with the aid of the present examples.
- the tensile strength and elongation at break values specified therein are determined in accordance with DIN 53857.
- a non-stretched nonwoven fabric with a weight per unit area of 220 g / m 2 produced by the usual spinning process has the following key figures:
- a fleece with 230 g / m 2 produced like the fleece used as the starting material, has a tensile strength lengthways of 650 N and crossways of only 290 N, and an elongation at break lengthways of 85%, crosswise of 125%.
- a nonwoven fabric which is produced by the same method as the starting nonwoven fabric, but has a basis weight of 180 g / m 2, has a longitudinal strength of 530 N and a transverse strength of 200 N, and an elongation at break of 95% and across 150%.
- a nonwoven fabric which is produced according to the same process as the starting nonwoven fabric, but has a basis weight of 200 g / m 2, has a tensile strength along 570 N, tensile strength across 230 N and an elongation at break along 90%, as well an elongation at break of 135%.
- a non-stretched nonwoven fabric with a weight per unit area of 150 g / m 2 produced by the usual spinning process has the following characteristics:
