摘要:
The compositions described are particularly useful for the treatment of textile fabrics to endow them with advantageous wearing properties, in particular enhanced hydrophilicity. The compositions comprise urea, thiourea or melamine derivatives, compounds comprising polyoxyalkylene groups and optionally an alcohol, and these components may optionally also have been reacted with each other.
摘要:
Disclosed are spray-on anti-soil formulations, and methods for treating fibers, carpets, and fabrics with the same. The anti-soil formulations comprise a synergistic blend of an anti-soil component and a stain blocker component adapted to be sprayed-on a fiber, carpet, or fabric instead of known exhaust applications. The anti-soil component can be either fluorochemical or non-fluorochemical based, while the stain blocker can comprise any chemical that blocks positively charged dye sites. Fibers, carpets, and fabrics treated with the anti-soil formulations exhibit superior anti-soil characteristics compared to sprayed-on fluorochemicals and exhibit similar anti-soil characteristics compared to known exhaust application.
摘要:
For the purpose of letting a fiber structure formed of polyester-based fibers have high hydrolysis resistance, spun fibers are treated by a terminal blocking agent, to have the terminal blocking agent taken up inside the fibers, for blocking the terminal carboxyl groups.
摘要:
Antimicrobial electret material are described. In some embodiments, the materials comprise a unitary web comprising an antimicrobial surface treatment and having certain properties. In other embodiments, an antimicrobial electret material is described comprising an electret web comprising an antimicrobial surface treatment wherein the surface treatment comprises a sparingly soluble silver-containing compound, a photosensitive antimicrobial agent that forms reactive oxygen species, a biguanide compound, or a combination thereof.
摘要:
The instant invention relates to a process for the finishing of textiles with a non formaldehyde cross-linking agent based on 2-imidazolidinones wherein by certain process parameters in drying and curing the undesired yellowing and unpleasant amine smell is avoided.
摘要:
Nanoscalar primary particles based on SiO2 or a mixed oxide of SiO2 and other metal oxides, in particular Al2O3, are disclosed. These particles have an average particle size ranging from 1 to 2000 nm (determined by the particle size measuring method that uses a Zetasizer NS (Nano Series)) and a negative charge, and can be advantageously used for producing a hydrophilic coating on textile materials. If required, a hydrophobic outer layer can be formed on the previously treated hydrophilic material, ensuring an enhanced alcohol and oil repelling effect, in comparison with a textile material without a hydrophilic intermediate layer. The nanoscalar primary particles can be used for this purpose in a particularly advantageous manner if they are added to the reaction solution in statu nascendi.
摘要:
Flame-retardant fabrics made from blended (polyamide imide and cellulosic) fibres, the cellulosic fibres being rendered flame-retardant by treatment with the reaction product of: (a) a tetrakis(hydroxyorgano) phosphonium salt; (b) an organic nitrogen compound; and optionally (c) an aliphatic, hydroxyl-reactive compound having at least one alkyl group containing 12 or more carbon atoms.
