摘要:
A flooring product comprises a heterogeneous design layer having multiple regions wherein two regions comprise compositions having different recycle content or renewable content. The thickness of the design layer may be greater than the dimensions of the regions or the regions may extending from the top surface of the layer to the bottom surface of the design layer. The heterogeneous layer may be composed of consolidated particles/chips which may contain a polyester binder system with a renewable component. Additionally, a method for making a heterogeneous layer having a target wt % recycle content or renewable content is also disclosed.
摘要:
Elastomers are formed from castor oil and/or ricinoleic acid estolides and a polyester formed from an epoxidized vegetable oil such as ESO and a polycarboxylic acid such as sebacic acid, optionally in the presence of a peroxide initiator, or include crosslinked reaction products derived from ricinoleic acid or castor oil estolides, epoxy group-containing compounds such as epoxy resins and/or epoxidized vegetable oil, epoxy hardeners such as polyamine and polycarboxylic acid hardeners, thermally activated free radical initiators such as peroxides, and optionally but preferably include fillers such as limestone or wood flour. The elastomers can be prepared using a two-step, solvent-less procedure at elevated or ambient temperatures. These predominantly “all-natural” elastomers have physical properties comparable to conventional petroleum-based elastomers and composites and exhibit good flexibility, resiliency, abrasion resistance and inertness to hydrolysis. The resulting elastomers display good mechanical strength and resiliency, are resistant to abrasion and hydrolysis, and can be processed into sheet materials, which makes them attractive as floor covering components.
摘要:
A preseamed, resilient sheet flooring including first and second composite sheet products positioned closely adjacent each other edge-to-edge to form a seam therebetween. An adhesive is positioned in the seam. The adhesive extends completely through the thickness of the sheet flooring, bonds with the first and second sheet products through the entire thickness thereof, and has visual characteristics suitable for creating an indistinct appearance of the seam in the sheet flooring product. The adhesive also has wear characteristics sufficiently similar to wear characteristics of the sheet flooring to maintain the visually indistinct appearance of the adhesive on the surface of the seam as wear occurs to the sheet flooring, thereby creating a finished seam sufficiently strong and flexible to permit the adhesive to be positioned in the seam prior to unrolling the flooring onto a subfloor surface.
摘要:
Phenolic foam which can be used as insulation is a foamed phenol-formaldehyde resole resin which contains a peptide, a proteinaceous material, cysteine, glutamic acid, glycine, isoleucine, leucine, lysine, phenylalanine, serine, tryptophan, or mixtures thereof at an amount effective to reduce emission of free formaldehyde from the foamed resin.
摘要:
A method for decreasing a polyamide textile material's affinity for acid dyes, which comprises pretreating the textile material with an acylimidazole compound.
摘要:
A method for improving the cationic or basic dye uptake of a polyamide textile material which is normally susceptible to anionic or acid dyes which comprises pretreating the polyamide textile material with a substituted trimellitic anhydride compound. The process of the present invention also decreases the textile material's affinity for acid dyes.
摘要:
The present invention discloses a method of photolytically developing a walnut wood color on a wood sample. The sample is contacted with a salt of an aminobenzenesulfonyl azide. The sample is thereafter exposed to a light source for an amount of time sufficient to produce a walnut wood color thereon.
摘要:
The present invention discloses a method of photolytically developing a colored image on a cellulosic material. In this method, the material is contacted with a nitrogen containing polymer in solution and a mono-sulfonyl azide compound in solution. The sample is thereafter exposed to a UV-containing light source for an amount of time sufficient to develop a color thereon.

摘要:
The present invention concerns our discovery that a water-soluble cationic dye and binder composition may be dissolved in a solvent, and, optionally, a magnetic material may be uniformly dispersed within said solvent solution. The resulting solution or mixture is agitated with a hot water solution comprising an ionizable salt whereby there is essentially no partitioning of the cationic dyestuff into the aqueous phase. During the intermixing step, the solvent is driven off, thereby providing a solid mixture of ink which may be pulverized and used in a wide variety of printing processes.
