Abstract
A process for producing a polymer nonwoven fabric includes providing a polymer blend of a thermoplastic elastomer and a further thermoplastic material. Fibers are produced from the polymer blend. A nonwoven semifinished product is formed from the fibers. In order to then produce the polymer nonwoven fabric, a volume increase is produced by mechanical stretching of the nonwoven semifinished product and subsequent relaxation. A process for using a semifinished nonwoven product and a process for using a polymer nonwoven are also provided.
Claims16
A process for producing a polymer nonwoven, the process comprising:
- providing a polymer blend of a thermoplastic elastomer and a further thermoplastic material;
- using only the polymer blend to produce one type of fibers and using the fibers to form a semifinished nonwoven product;
- and
- producing the polymer nonwoven by mechanical stretching and subsequent relaxation of the semifinished nonwoven product to achieve an increase in volume.
A process for using a semifinished nonwoven product formed from one type of fibers produced only from a polymer blend formed from a thermoplastic elastomer and a further thermoplastic material to produce a polymer nonwoven or an acquisition/distribution layer formed from the polymer nonwoven, the process comprising:
- mechanically stretching and subsequently relaxing the semifinished nonwoven product causing an increase in volume of the semifinished nonwoven product and producing the polymer nonwoven.
