Abstract
Provided are methods for preparing fabric laminated with polymer film(s) and the laminated fabric prepared according to the methods disclosed herein. The laminated fabric has flexibility similar to fabric not laminated with polymer films and improved adhesion and tensile strength.
Claims20
A method for preparing a laminated fabric material comprising the following steps:
- a) preparing a binder-treated fabric material comprising:
- a-i) applying a binder dispersion to a fabric substrate to provide a binder dispersion-treated fabric material, the binder dispersion comprising a binder and a dispersion solvent, and the dispersion solvent comprising a first solvent and optionally a co-solvent miscible with the first solvent;
- a-ii) removing at least about 50% of the dispersion solvent of the binder dispersion-treated fabric material to provide a dried binder dispersion-treated fabric material, at a temperature of about 10° C. lower than the boiling point of the first solvent for about 10 to about 90 minutes;
- and
- a-iii) curing the binder in the dried binder dispersion-treated fabric material to provide a binder-treated fabric material at a temperature of about 160° F. to about 280° F. for about 10 minutes to about 90 minutes, the binder-treated fabric material gains about 3% to about 8% weight compared to the fabric substrate before the binder treatment;
- and
- b) laminating a polymer film to the binder-treated fabric material to provide a laminated fabric material comprising
- b-i) applying a first film on a first side of the binder-treated fabric material;
- b-ii) applying a second film to another side of the binder-treated fabric material;
- to provide a laminated fabric material;
- and
- b-iii) laminating the films to the binder-treated fabric material to provide the laminated fabric material.
