摘要:
Dye receptivity of fibers used in the dyeing and printing of cationic dyeable nylon as used as carpet fibers or similar polymers difficult to dye with anionic dyes are improved by a coating rendering these fibers more receptive to anionic dyes.

By utilizing recovered polyvinyl butyral in the production of carpet backcoatings, the amount of waste polyvinyl butyral that is landfilled or otherwise disposed of is significantly reduced, as is the need for manufacturing polyvinyl butyral. The recovered polyvinyl butyral is size reduced and then utilized by itself or with other ingredients to provide a composite used in the manufacture of a useful product (like carpet backing), and then the composite material is used to make the useful product (such as carpet backing, which is used as a primary or secondary backcoating in the manufacture of new carpeting or as a precoat, main back coat or combination precoat/main back coat in the manufacture of new carpet tile). In addition, waste carpet may optionally be used with the recovered polyvinyl butyral as a filler material; thus, further reducing the amount of waste that is landfilled or incinerated.

The amount of waste carpeting that is landfilled or otherwise disposed of is significantly reduced, as is the need for the mining mineral fillers, by utilizing specially processed waste carpeting as a filler in the production of new hot melt carpet backcoating, roofing materials, or other similar products. Waste carpeting (post-consumer and/or waste from new carpet manufacture) is collected and size-reduced, typically in a first coarse size-reduction, and then after densification to a finer size-reduction. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a hot melt composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting). The waste carpeting may provide between about 40-100% of the filler of carpet backcoating, with any remainder made up by conventional fillers, such as calcium carbonate.

Waste carpeting (post-consumer and/or waste from new carpet manufacture) containing calcium carbonate and a thermoplastic resin is collected and size-reduced to a size corresponding to the size of calcium carbonate typically used as a filler. The size-reduced waste carpeting is added as filler to at least one other material, such as polymers in standard latex, EVA, or PVC carpet backcoatings, to provide a composite used in the manufacture of a useful product (like carpet backcoating), and then the composite material is used to make the useful product (such as carpet backcoating, which is used as a primary or secondary backcoating in the manufacture of new carpeting). The waste carpeting may provide between 0–100% of the filler of carpet backcoating, with any remainder made up by conventional fillers, such as calcium carbonate.

摘要:
The effects of ultraviolet induced damage to cationic dyeable nylon fibers dyed at a pH of about 2.5 or less with an acid dye, a premetallized acid dye or a reactive dye are arrested or attenuated by applying to the dyed fibers either before of after exposure to ultraviolet light a neutralizing aqueous solution having a pH of about 7.5 or greater and heating the fibers.
摘要:
Colorfastness of cationic dyeable nylon fibers dyed with acid and/or premetalized acid dyes is enhanced and potential water bleed problems can also be overcome by treating the dyed fibers with an acrylic water bleed fixative in conjunction with a traditional cotton water bleed fixative. In a typical procedure, the acrylic fixative is applied first, followed by the nylon fixative or the cotton fixative.
摘要:
A process for arresting or attenuating ultraviolet induced damage to nylon fibers comprising dyeing cationic dyeable nylon fibers at a pH of about 2.5 or less with an acid dye, a fiber reactive dye or premetallized acid dye and, subsequent to exposing said fibers to fiber damaging amounts of ultraviolet light, applying a neutralizing aqueous solution having a pH of about 7.5 or greater to said fibers, thereby arresting or attenuating ultraviolet induced damage to said nylon fibers. The nylon fibers may be in a carpet which may be treated after installation.
