摘要:
Provided herein is a photocatalytic substrate comprising a textile support and a finish on at least a first surface thereof. The finish on at least the first surface of the textile support comprises a particulate photocatalytic material and a binder. On the opposite surface of the textile support is disposed a coating comprising activated carbon particles and a binder. Also provided is a process for producing such photocatalytic substrates.
摘要:
A flame retardant composition comprises a phosphorous-containing polymer. The phosphorous-containing polymer can be produced by first reacting a phosphonium compound and a nitrogen-containing compound to produce a precondensate compound and then reacting the precondensate compound with a cross-linking composition. The resulting phosphorous-containing intermediate polymer can then be oxidized to convert at least a portion of the phosphorous atoms in the polymer to a pentavalent state. A textile material comprises a textile substrate and a phosphorous-containing polymer, such as that described above.
摘要:
A textile material comprises a plurality of dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising polyphenylene sulfide fiber, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180° C or more to fix the disperse dye to the polyphenylene sulfide fibers.
摘要:
A fabric comprises a plurality of yarns, at least a portion of which comprises polyphenylene sulfide fibres and regenerated cellulose fibres. The fabric comprises 35 wt.% or more polyphenylene sulfide fibres. A fabric comprises a plurality of yarns, each yarn comprising a plurality of polyphenylene sulfide staple fibres and a plurality of regenerated cellulose staple fibres. A method of protecting an individual from injury caused by molten metal splashes comprises the steps of providing a fabric, providing a source of molten metal, disposing the fabric between the source of molten metal and an individual, whereby the fabric serves as a barrier to protect the individual from molten metal splashes.
摘要:
A filtration medium comprises a textile substrate and a mercury abatement coating on a least a portion of the surface of the textile substrate. The mercury abatement coating comprises a copper salt, a binder, and other optional components. A process for removing mercury from a gaseous stream uses the filtration medium.
