Prior to application of the flame retardant composition of the present invention, the fabric typically used is free of impurities, aperitures, natural waxes, and applied finishing agents even if they contain optical brighteners.

The process of finishing with the flame retardant composition of the present invention can also be used to treat fabrics on carpets (by applying this composition to the back), wherein the weight of these fabrics can be as high as 2 kilosramv / m 2.

The flame retardant particle size of the present invention, which typically has a pH of from 2 to 8, such as from about 5.5 to about 7.5, is applied to the fabric substrate of the process-coated substrate (or bottom). ) a sided fabric using a knife device placed over a cylindrical member to distribute the composition of the present invention on a fabric substrate, or to distribute the composition of the invention according to the invention, or preferably using a rotary screen, optionally in combination the application rate or application rate with the aforementioned ratio is in these 24 cases ranging from about 5% to about 150%, or this application rate ranging from about 50% to about 150% (based on fabric weight), such as 60% to 80% for pile fabric or 80% to 120% for a well mixed mixture fibers or mixed fabrics. The minimum application rate required to achieve adequate flame retardancy in these fabrics is usually the application rate required to saturate the fabric (especially for porous fabrics) or not to mention that this application rate is at least 95%, however, lower application rates may be used.

After the impregnation is carried out, the substrate to be treated can be dried, for example, at a temperature of from 80 to 1 minute for 0.1 to 10 minutes. This drying can be carried out in any commonly used drying apparatus, such as a forced air drier or a damping ram.

The impregnated substrate thus obtained is, after drying, subjected to a thermal curing step, if desired, for example by heat at a temperature of at least 80 ° C, such as at least 120 ° C, for example in a temperature range of 120 to 170 ° C. The present invention uses a temperature range of from 140 to 170 ° C or from 140 to 165 ° C, and this heat curing is performed over a period of from 6 minutes to 0.5 minutes. In choosing the times and temperatures mentioned above, it is usually preceded by combinations involving high temperatures and long curing times to reduce any tendency to color the fabric substrate.

In a preferred embodiment, the drying and curing is combined into a co-molded one. The above curing, which takes place in a conventional manner, can be carried out by irradiation, such as infrared irradiation, while heating the fabric substrate, but in a preferred embodiment of the present invention, the curing is performed by heating the substrate with the hot air on the fabric substrate. In a preferred embodiment, both sides of the fabric substrate are provided to provide uniform heating from both sides. It follows from the foregoing that it is advantageous to conduct the fabric substrate in a continuous manner on the tensioning and drying frame by a drying device maintained at a constant temperature in which heated air streams are directed to the bottom and top of the fabric substrate. Although this curing step is carried out on the tensioning drying frame, the most even curing is achieved by minimal scorching. In the case of a drying device using a tensioning and drying frame, the curing temperature for a given fabric substrate is substantially the same as that of the heated air stream used in this drying and curing process. This curing of the fabric substrate performs a rapid cooling of the fabric substrate by passing or sucking cold air over the fabric substrate. Fact treated fabric has a solids content of 30 to 60% by weight, such as 35% to 45% by weight for woven fabrics, or 50% to 60% for blended fabrics or other non-woven fabrics after final curing; this fabric usually contains 3% to 10% phosphorus 1, preferably 5% to 8% phosphorus P, after the final treatment. The fabric thus treated has a reduced flammability after the final treatment compared to the untreated fabric substrate, with 26 meets the BS 5852 test with gear sources

This fabric one by one Craving the hard water emotion at 40 ° C, carried out according to BS 5651, without performing the final ironing of the fabric, fulfills the BS 5552 Part 1 Flammability Test with ignition sources 0 and 1. This reduced flammability can be maintained after 1-3 washings in soft water at 74 ° C or after 10 dry cleaning operations, depending on the nature of the resin used. Typically, this fabric typically has a substantially unchanged face (or playing side) compared to the untreated fabric, with no surface sedimentation or staining of the resin used. This treated fabric does not have substantially altered coloration compared to the color of the untreated fabric.

This synergistic combination of components (i) to (IV), in particular in combination with components (V) and (VI), is suitable for the treatment of textile substrates, such treated fabrics having improved flame retardant properties while simultaneously In particular, woven fabrics having a backing and a face side do not cause the salt or resin to leach on the face of the fabric in the event that the composition is applied to the underside (or bottom) side. It is believed that a certain proportion of water and some water-soluble ammonium polyphosphate added as such to the inventive or water-insoluble polyphosphate component migrates from the underside (or underside) towards the key side (or top) , however, it will not reach this face. Exemplary embodiments of the invention are further illustrated, by way of practical examples, by a flame retardant composition which is applicable to fabrics and a fabric treatment process to provide flame retardant fabrics.
