Abstract

The invention provides a method for cutting a composite membrane material, firstly, manufacturing a composite membrane material, the composite membrane material is formed by combining an elastic membrane material with at least one shaping membrane, the elastic membrane material has stretchability and elasticity; the shaping membrane is capable of dissolving in water, and a rigidity thereof is greater than that of the elastic membrane material, and a ductility thereof is lower than that of the elastic membrane material; and cutting the composite membrane material into a plurality of composite filaments with a cutting device, and each of the composite filaments comprises an elastic filament and at least one shaping filament. The composite filament can be used by textile machinery to make textiles. Dissolving the shaping filament in the composite filament is capable of obtaining the elastic filament.

Dependent claims

A method for cutting a composite membrane material with an elastic membrane material comprising:

manufacturing a composite membrane material, the composite membrane material being formed by combining an elastic membrane material with at least one shaping membrane, the elastic membrane material being made of high-molecular material with stretchability and elasticity;
the shaping membrane being made of high-molecular polymer, having solubility and being capable of dissolving in water;
a rigidity of the shaping membrane being greater than that of the elastic membrane material, and a ductility of the shaping membrane being lower than that of the elastic membrane material;
and
cutting the elastic membrane material and the shaping membrane of the composite membrane material with a cutting device, and cutting the composite membrane material into a plurality of composite filaments, each of the composite filaments being a composite with at least two layer structures, comprising an elastic filament and at least one shaping filament, the elastic filament being formed by being cut out from the elastic membrane material;
and the shaping filament being formed by being cut out from the shaping membrane.
