New textile chemicals and dyestuffs from Clariant

30 October 2008, Muttenz, Switzerland - Clariant has recentlydeveloped and launched worldwide a range of versatile new products.
Further information on the products summarized below is availableat: www.textiles.clariant.com.
NEW DYESTUFFS
Foron Black AS-3LF
Foron Black AS-3LF is a new disperse dyestuff for high light-fastapplications and the successor to Foron Black AS-LF. A highlight-fast and hot light-fast black disperse dyestuff, it is 30%stronger than Foron Black AS-LF and characterized by good build-up.It achieves a neutral shade under different light sources and lowcolor fading after exposure to light.
It is suitable for complying with all common automotivelight-fastness standards and characterized by excellent sublimationfastness up to 180°C at 30 seconds, with very goodcombinability with UV-absorbers such as Clariant’s Fadex.
Foron Dark Blue S-WF
Foron Dark Blue S-WF is being introduced to cover a current colorspectrum matching gap and is intended to be employed as a baseelement for dark blue and navy shades. It displays a better cottonreserve when compared to Clariant’s Foron Navy S-WF and istherefore an excellent choice for PES/cotton blends. Due to itsexcellent exhaust behavior and very high sublimation fastness,Foron Dark Blue S-WF is suitable for both exhaust and continuous(SWIFT) applications.
Nylosan S range
Clariant is also introducing three new patented additions to itsNylosan S range. All three dyestuffs are suitable for polyamide– particularly PA/PU microfibers – and wool fibers, andrepresent state of the art in respect of wet fastness within theAcid Super Milling Dyestuff Class. Unlike conventional Millingdyestuffs, however, these Nylosan S products have a very highdegree of compatibility. In combination with Lanasyn F, they aresuitable for a range color effects from the most intense brightcolors to the deepest dull ternary shades. Application of theseproducts is comparable to existing conventional acid dye methods.
The three new products are:
· Nylosan Orange S-3R A metal-free, bright reddishternary orange element which fits the color space between theexisting Nylosan Yellow S-L and Nylosan Red S-GS products.
· Nylosan Red S-3B A metal-free, bluish-red ternaryelement for the color space between the existing Nylosan Red S-Band Nylosan Blue S-R products.
· Nylosan Navy S-3G A metal-free, greenish navyternary element for use as a dark blue ternary element, in additionto the production of a number of navy and black shades.
All three new elements exhibit almost identical performance.
In respect of polyamide, they offer:
· Very high build up (even on microfiber).
· Very high fastness to washing, perspiration andwater.
· Slight-to-moderate polyurethane stain.
· Moderate-to-good light-fastness.
· A high degree of compatibility with new andexisting Nylosan S dyestuffs.
For wool they provide:
· Very high processing fastness in respect ofalkaline milling, overdyeing, decatising, chemical setting and hotwater, in addition to high wet fastness to washing andperspiration.
· Maximum wool protection, dyeing in theiso-electric region and no need for alkaline clearing.
· Moderate-to-good light-fastness.
· A high degree of combinability with new andexisting Nylosan S dyestuffs.
Diresul Indinavy RDT-B and Diresul Indiblack RDT-2R
Advanced Denim is a new concept launched by Clariant at thebluezone fair in Munich in September. It is based on maximizedsulphur dye products, technologies and applications, and takesenvironmental concerns into consideration while complying withhealth and safety standards.
The Advanced Denim concept is also designed to meet the demands oftomorrow’s denim fashions in respect of both style andquality performance. To complement the existing Diresul RDT dyerange, Clariant has introduced Diresul Indinavy RDT-B liquid, whichenables deeper and faster blue shades to be achieved and offers themarket new and interesting effects, in addition to DiresulIndiblack RDT-2R liquid for black, grey and blue effects.
The latest Diresul RDT dyes are suitable for both Indigo andIndigo-free denim applications and enable biodegradable dyeing withreducing agents as well as innovative application procedures thathelp to save substantial quantities of water, time and energy(Pad-Ox).
Imacol C3G liq
Imacol C3G liquid is a highly-effective lubricant for dyeingcellulose fibers and blends. It reduces fiber metal friction at allstages of textile wet processing, is highly effective over a widepH range, does not impair the shade and fastness properties ofdyeing and is non-foaming and very economic in use.
NEW FINISHING CHEMICALS
Nuva 1910 liq
Nuva® 1919 liquid for cotton and PA-based fabrics achievesexcellent initial performance as well as good durability. Theproduct also works well on PES, where only low durabilityrequirements are in place. Because the product has a good chemicalcompatibility, it can even used be successfully with selected fireretardants. Nuva 1910 liq is developed from fluorocarbon technologywith a polyamide-based cationic copolymer that significantlyimproves the efficiency of the fluorocarbons.
NEW FIBER FINISHES
Afilan FOX liq
Afilan FOX is a spin finish for the spinning of polypropylene BCF(bulked continuous filament), CF (continuous filament) yarns andmultifilaments. It is suitable for undyed as well as solution-dyedyarns and can be applied either as neat oil or as an aqueoussolution (at a concentration of around 10-20 % with oil-pick up of0.8-1.4%).
Afilan FOX liq can be easily diluted with water in any ratio andprovides well-balanced friction and cohesion properties. It hasexcellent antistatic properties and an optimized thermo stability.
Afilan AKT liq
Afilan AKT liquid is a highly-efficient antistatic agent with astrong anti-corrosive effect for use in the manufacturing ofpolyester, polypropylene, polyamide or acrylic staple fibers. It isapplicable by spraying, padding or immersion and usually does notyellow white goods, even at higher drying and thermosettemperatures. Based on high quality raw materials, Afilan AKT liq.has no effect on the shade or fastness properties of dyed goods andalso does not cause thermomigration.
