摘要:
Described herein are modification of fabrics using a microwave initiation technique to produce a porous coating on the fibers providing adsorbent properties as well as the potential for further modification. In embodiments, the fabric incoporates a periodic mesoporous organosilica compound (PMO) optionally bound to a porphyrin or other functional group, and/or a catalyst or optical indicator.
摘要:
Flame resistant fabrics having antimicrobial properties that combat odor and/or resist hazardous microorganisms. The fabrics are particularly suitable for use in clothing and more particularly in protective garments designed to be worn by individuals, such as military personnel and emergency rescue personnel, at risk of exposure to fire and extreme temperatures as well as hazardous substances. The fabrics may be formed in a variety of ways, including, but not limited to, incorporating antimicrobial fibers into the flame resistant fabric yarn or by treating the pre-formed flame resistant yarn or fabric with antimicrobial agents in a dyeing or finishing process.
摘要:
Described is the use of a laundry detergent that includes at least one optical brightener from the class of the stilbene compounds for the antimicrobial finishing of textile fibre materials, which comprises washing the fibre materials with this laundry detergent and subsequently exposing the washed textile material to a light source.
摘要:
The present invention provides new compounds having formula (1), in which X is O or, preferably, NH; M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; each R1, independently, is an aminoacid residue from which a hydrogen atom on the amino group has been removed; n is 1 or 2; and each R2, independently, is hydrogen, C1-C3alkyl, halogen, cyano, COOR in which R is hydrogen or C1-C3alkyl, CONH-R in which R has its previous significance, SO2NH-R in which R has its previous significance, NH-COR in which R has its previous significance, SO3M in which M has its previous significance or, when n is 1, R2 can also be CO-R3 in which R3 is C1-C3alkyl or phenyl; provided that those compounds are excluded in which a) X is NH, n is 1 and R2 is SO3M in which M has its previous significance; or b) X is NH, n is 2 and one R2 is SO3M in which M has its previous significance, and the other R2 is hydrogen, methyl or halogen; or c) X is NH, n is 1, R1 is glycine and R2 is H or CO2H; or d) X is NH, n is 2, each R2 is SO3M in which M has its previous significance and the SO3M groups are in 2,5-positions in the phenyl ring and R1 is D,L-alanine, L-valine, L-leucine; L-isoleucine, L-threonine, L-aspartic acid, L-glutamic acid, L-phenylalanine, L-proline, D,L-methionine or glycine. Most of the new class of 4,4'-diaminostilbene-2,2'-disulfonic acid compounds are useful as fluorescent whitening agents, especially for paper.
摘要:
An optical brightener of the bis-s-triazinylaminostilbene series having at least one fiber reactive vinyl sulfone substituent. The compounds of the invention provide high whiteness at low application levels.
摘要:
The current invention provides for a composition and method for the improvement of fabric release in applications such as tissue and towel making processes. The method comprises treating the surface of a fabric in structured sheet making applications using compositions containing hydrophobic quaternary aminoamides (such as imidazolines) in combination with other hydrophobes and surfactants.
摘要:
The invention relates to a textile treatment composition comprising an organic acid, an inorganic acid, a nonionic surfactant and a deodorant compound, which removes or reduces the formation of encrustations, discolorations and bad odours in textiles, which result from the use of deodorants.
摘要:
A process for improving the sun protection factor (SPF) of cellulosic fibre materials and blends thereof, which comprises contacting said materials with at least one compound of the formula (1): (Formule 1); in which M is hydrogen, an alkali metal atom, ammonium or a cation formed from an amine; R, and R,' independently of each other are -NH-R3, -N(R3)2 or -0-R3, wherein R3 is aryl substituted by -CO-X-R5, wherein X is O or NH and R5 is optionally substituted C1-C4-alkyl, R2 is a group of formula -0-R4 wherein R4 is hydroxy alkyl, alkoxy alkyl or hydroxy alkoxy alkyl, and R2' has the meaning of R1 or R2.
