What is Pyrovatex®
Uses
PYROVATEX® CP NEW / CP-LF is a flame-retardant finish for textiles of cellulose fibers and fabric blends with a synthetic component of up to 25% (low blends; depending on fiber quality, fabric construction / weight and required FR standard). The effects are resistant to washing at the boil and dry cleaning, provided the care instructions are observed (see § care instructions).
Chemistry
PYROVATEX® CP NEW / CP-LF is based on a dialkylphosphonocarboxylic acid amide with the general formula:
PYROVATEX® CP NEW / CP-LF, which is preferably used together with methylolamine precondensates, reacts with the hydroxyl groups of the cellulose. Any unfixed PYROVATEX® CP NEW / CP-LF or acid from the catalyst is removed by alkaline washing off – an integral step in the finishing process.
PYROVATEX® CP NEW / CP-LF is different from other flame retardant finishing systems in which resistance to washing is mainly due to enlargement of the molecules of the finishing agent.
Strade
Moreover, PYROVATEX® CP NEW / CP-LF also differ from flame retardant finishing products for synthetic fibers in its chemistry and the way it bonds to the fiber.
Mode of action
If flames or heat come into contact with flame retardant finished cellulose, a carbon scaffold is formed by dehydration of the cellulose, counteracting heat penetration and the spread of fire. In contrast to untreated cellulose, almost no flammable gases are formed by pyrolysis and this stops combustion. Protection and Comfort 3 Checklist for optimum application of PYROVATEX® CP NEW / CP-LF
Substrate
Weight per unit area Must not be less than 150 g/m2
Composition Cotton, viscose, linen
Any synthetic component must not exceed 15% (intimate blend with cellulose) if the finished goods are required to pass a vertical test with edge flame application. Higher synthetic fiber contents are feasible for goods required to pass horizontal and surface flame impingement tests.
Dyeing / Printing Preliminary trials should be carried out to ascertain whether the dyes used are suitable for a PYROVATEX® finish (shade, fastness, effect of pigment or dye). Sulfur black dyeings must be thoroughly rinsed before the finish is applied.
Absorbency The goods must be suitably pretreated (desized, scoured) to insure good absorbency. We advise against oxidative desizing because the tenacity is reduced.
PH The goods must be free of alkali and other extraneous matter and have a pH of 5 – 7. Machinery required Pad mangle / Impregnation trough Permits a long dip Stenter With overfeed and efficient ventilation and which can be heated up to 130ºC (170ºC if used for curing). Batching device at exit. Curing oven / Backer 4 – 5 min at 150°C Open width washing machine 5 boxes or more, winch or jig Sanfor Machine If necessary
