    摘要: Provided are compounds and methods for modifying a material to change properties of the material, as well as a variety of products obtained using the methods. In one embodiment, a material comprising one or more modifiable functional groups is reacted with an activated hydrophobic acyl group in the presence of a hindered base, thereby to covalently attach the hydrophobic acyl group to the modifiable functional groups on the material. The material which is modified may be, for example, a carbohydrate, and the modifiable functional groups on the material may be hydroxyls. For example, materials such as cellulose may be modified by reacting it with a acid chloride or acid anhydride including a hydrophobic acyl group, in the presence of a hindered base, such as tripentylamine, to attach the hydrophobic acyl groups to the hydroxyls on the cellulose, thereby to increase the hydrophobicity of the cellulose. The methods and compounds disclosed herein may be used to modify materials to improve properties such as resistance, grease repellency, soil resistance and permanent press properties.

    摘要: The present invention is directed to thermo-expandable fibers and to the expanded hollow fibers or microtubes, microcellular foam or foamed composite material that results upon heating the expandable fibers. The thermo-expandable fiber of the present invention is characterized by having a polymeric wall surrounding one or more pockets or particles of blowing agent or propellant within the fiber. The polymeric wall may have reactive functional groups on its surface to give a fusible fiber. When the expandable fibers are heated, they expand to form hollow fibers or microtubes comprising polymeric shells surrounding one or more internal gaseous voids, and when the fibers are expanded while in contact with each other, a microcellular foam may be formed. The foam consists of a plurality of hollow fibers fused together, optionally aided by functional groups present on the surface of the heated fibers that act to crosslink the material. When expandable microspheres are mixed with a matrix, which can optionally react with functional groups on the fiber surface, and the resulting combination is heated, the fibers expand to give a foamed composite material in which the hollow fibers or microtubes may optionally be fused or chemically crosslinked to the matrix.

    摘要: This invention is directed to treatments for dyed textile goods that will improve their fastness properties. More particularly, the invention is directed to certain fixatives that, when placed on the dyed textile, allow the dye to be permanently or substantially permanently affixed to the fabric. The dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer having reactive groups that react with a dye on a dyed web to affix the dye to the web.

    摘要: The invention is directed to fiber-reactive polymeric dyes, which comprise a dye covalently bound to a carboxyl-containing polymer. By nullfiber-reactivenull is meant that the polymeric dye will form a chemical covalent bond with the fiber, textile, or web to be treated, via functional groups for binding or attachment to the fibers of the webs to be dyed. The invention also encompasses textile dye preparations comprising a solution or suspension of the fiber-reactive polymeric dye. The resulting polymeric dye preparations have improved colorfastness and retention on the textile or web fiber structure, even after a large number of washings. The textiles or webs treated with the fiber-reactive dye are also included in the invention.

    摘要: The present invention relates to textile treatment compositions for imparting desirable characteristics durably to textile fibers and fabrics, including softness, hydrophobicity, oleophobicity, surface lubricity, abrasion resistance, tear resistance, improved drape, and pilling resistance. More particularly, in one embodiment, the invention is directed to preparations that comprise a carboxylate-functionalized fluorinated polymer and a catalyst that is capable of forming reactive anhydride rings between carboxyl groups on the polymer. In another embodiment, the invention is directed to preparations comprising a polymeric softener having at least one anhydride functional group or at least one reactive group capable of forming an anhydride functional group, together with a catalyst for forming anhydrides from the reactive group or groups. In either embodiment, the resulting reactive anhydride rings bind to substrates, such as textiles and other webs, having free sulfhydryl, alcohol, or amine groups. The invention is further directed to the process for treating textiles and other webs with desirable finishes durable to repeated cleanings. This invention is further directed to the yarns, fibers, fabrics, textiles, finished goods, or nonwovens (encompassed herein under the terms nulltextilesnull and nullwebsnull) treated with the textile-reactive preparations of the invention. Such textiles and webs exhibit a greatly improved, durable characteristics, such as softness and/or hydrophobicity, even after multiple launderings.

    摘要: The present invention is directed to microemulsion techniques for rapidly preparing photochromic glass nanoparticles and to the photochromic glass nanoparticles so prepared. More particularly, the method of the invention comprises the combination of two microemulsions, one containing a water-soluble silver salt and a glass precursor and the other containing a halide salt and an initiator for glass formation, which process rapidly yields silver halide particles. This invention gives nanometer-sized silver halide particles embedded in glass, thus providing photochromic glass nanoparticles without further annealing, or at most mild annealing. These nanoparticles are valuable as added components to any macro-material that one might wish to have photochromic properties. The particles would impart photochromism while not affecting the physical properties of the material.
