Abstract:
A process for producing an evenly-dyed fabric comprising both cotton fibres and man-made cellulose fibres, in which a fabric is manufactured from both said fibres and is dyed, is characterised by impregnating the man-made cellulose fibres, prior to manufacture of the fabric, with a water-soluble, flexible linear polymer and a cross-linking agent reactive with cellulose, and, at a stage of the process prior to dyeing of the fabric, effecting a cross-linking reaction between the man-made cellulose fibres and the cross-linking agent, thereby producing a reduction in the dye affinity of the man-made cellulose fibres to a level more proximate to the dye affinity of the cotton fibres.
Abstract:
Dyed poly(trimethylene terephthalate) fibers having a lightfastness of 4 or higher after 480 kJ incident UV radiation, and processes for preparing the fibers, are provided. The fibers are useful in automotive applications and other uses wherein UV absorption is likely.
Abstract:

Abstract:
The present invention provides an aqueous composition comprising: (a) a melamine that is at least partially derivatised with an aliphatic hydrocarbon group having at least 8 carbon atoms; (b) a wax; and (c) at least one component selected from the group consisting of (i) a reaction product of an aliphatic polyisocyanate and an organic compound having one or more groups capable of reacting with an isocyanate, said reaction product having free isocyanate groups and having a molecular weight of at least 350 g/mol and (ii) a blocked aromatic polyisocyanate. The compositions can be used to treat textile to provide good water repellency properties thereto.
Abstract:
The invention relates to "closed loop" processes, systems and compositions for providing flame retardant properties to substrates containing at least about 5 weight percent of non-thermoplastic material, such as non-thermoplastic fibers, fibrous compositions or fabrics, and to treated substrates. The processes and systems are environmentally friendly, and advantageously conserve chemical compounds and water by recycling flame retardant composition. The processes generally comprise: (a) applying a flame retardant composition containing one or more flame retardant substances, an aqueous liquid and one or more adhesion agents to substrates; (b) removing excess flame retardant composition from the substrates; (c) permitting the substrates to dry to a low moisture content; and (d) recycling excess flame retardant composition; wherein the flame retardant composition does not contain an amount of a dye or other agent that could contaminate the flame retardant composition.
Abstract:
A stabilizer composition comprising (A) a compound of the formula (I) wherein R is (CH 2 -CH 2 -O-) n ,-R 2 ; -CH 2 -CH(OH)-CH 2 -O-R 2 ; or -CH(R 3 )-CO-O-R 4 ; n is 0 or 1; R 2 is C 1 -C, 13 alkyl or C2C 20 alkenyl or C 6 -C 12 aryl or CO-C 1 -C 18 alkyl; R 3 is H or C 1 -C 8 alkyl; R 4 is C 1 ,-C 12 alkyl or C 2 -C 12 alkenyl or C 5 C 6 cycloalkyl; and (B) one or more compounds selected from benzotriazoles of the formula (IIa), 2-hydroxybenzophenones of the formula (IIb), oxalanilides of the formula (IIc), 2-hydroxyphenyltriazines of formula (IId), cinnamates of formula (IIe), and benzoates of formula (IIf) as defined in claim 1, is especially effective towards stabilizing organic materials against degradation induced by light, heat or oxidation.
Abstract:
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), whereby R1 represents hydrogen or C1-C4alkyl; R2 represents hydrogen, c1-c4alkyl, C1-C4alkoxy, halogen or SO3M, M being hydrogen or an alkali or alkaline earth metal; X1 is chlorine, fluorine, NR3R4, OR3 or SR3, wherein R3 represents hydrogen, C1-C4alkyl or C1-C4alkoxy, which are unsubstituted or substituted by one or more SO3M, OSO3M, COOM or OH groups, C2-C4hydroxyalkoxy, C1-C4alkoxy-C1-C4alkoxy or phenyl, which is unsubstituted or substituted by one or more SO3M, COOM, OH, halogen or C1-C4alkyl groups and R4 represents hydrogen, C1-C4alkyl, C2-C4hydroxyalkoxy, C1-C4alkoxoxy-C1-C4alkoxy or phenyl, or R3 and R4, together with the nitrogen atom, form a pyrrolidine, piperidine or morpholine ring; X2 is chlorine, when X1 is chlorine, or X2 is fluorine, when X1 is, NR3R4, OR3 or SR3 and Z is a fibre reactive group, whereby the cellulosic fibre material may also be treated with a fluorescent whitening agent either before, during or after contact with the compound of formula (1).
