Articles, such as garments, including films comprising dried aqueous polyurethane dispersions are disclosed, whereby the garment has an altered stress which is exhibited during wear of the garment and/or has one or more sections of waterproof or water-resilient fabric. The film may be bonded to the fabric of the article to provide a fabric or film laminate.

Garment incorporating waterproof or water resilient aqueous polyurethane dispersions and/or having altered stress profile

Articles, such as garments, including films comprising dried aqueous polyurethane dispersions are disclosed, whereby the garment has an altered stress which is exhibited during wear of the garment. The film may be bonded to the fabric of the article to provide a fabric or film laminate.

Garment incorporating aqueous polyurethane dispersions having altered stress profile

Aqueous polyurethane dispersions, prepolymers for formation of these dispersions, methods for their use in shaping articles, as well as shaping articles produced thereby are provided.

Aqueous polyurethane dispersions, prepolymers, and shaped articles made therefrom

Articles including a polymer film, a plasticizer and a substrate are included. A method of bonding the film to the substrate includes the use of the plasticizer which provides a durable bond by using a lower temperatures and shorter bonding times than would be required in the absence of the plasticizer.

Bonding of heat-activated films including a plasticizer

Included are articles such as garments including polymer film compositions to alter the stress profile of the garment which is exhibited during wear of the garment. The polymer film may be bonded to the fabric to provide a fabric/film laminate.

Garment with altered stress profile

Articles comprising garments with at least one opening layers are included. The articles may include an elastic polymer composition such as a film, a melt or an aqueous dispersion.

Garment bands including polymer compositions

Novel aqueous polyurethane dispersions and shaped three dimensional articles formed therefrom are provided. The aqueous polyurethane dispersions are provided in solvent-free systems of a prepolymer comprising at least one polyether, polyester, or polycarbonate polyol, a mixture of MDI isomers, and a diol. The shaped articles from such dispersions can be heat-activated for bonding, lamination, and adhesion of substrates, including stretch fabrics.

Solvent free aqueous polyurethane dispersions and shaped articles therefrom

Novel aqueous polyurethane dispersions and adhesive films formed therefrom are provided. The aqueous polyurethane dispersions are provided in solvent-free systems of a prepolymer comprising at least one polyether or polyester polyol, a mixture of MDI isomers, and a diol. The adhesive films from such dispersions can be heat-activated for bonding, lamination, and adhesion of textile fabrics, including stretch fabrics.

Solvent free aqueous polyurethane dispersions and adhesive films therefrom for stretch fabrics

The invention provides a process for treating a polyester fiber comprising the steps of providing a bicomponent fiber comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) which has been heat-treated at a first temperature and cooled to lower than about 70&#xb0; C. and has an initial crimp contraction value and a developed crimp contraction value, applying tension to the fiber of about 0.001 to 0.088 dN/tex, heat-treating the fiber at a second heat-treating temperature no lower than about 75&#xb0; C. and no higher than the first heat-treating temperature, cooling the fiber to lower than the second heat-treating temperature, and releasing the tension from the fiber to give a fiber having a reduced crimp contraction value. The invention also provides a bicomponent fiber comprising poly(ethylene terephthalate) and poly(trimethylene terephthalate) having a reduced crimp contraction value of about 6% to 15%.

Process for treating a polyester bicomponent fiber

A woven fabric comprising warp fibers and a weft is provided. The weft may be of pick-and-pick or co-insertion constructions. The weft includes a spun staple yarn and a polyester bicomponent filament. The polyester bicomponent filament includes poly(ethylene terephthalate) and poly(trimethylene terephthalate), and has an after heat-set crimp contraction value of from about 10% to about 80%. A process for making such a fabric is also provided.
