Abstract
A flame retardant corn position for textile material and carpets comprising an aqueous solution of inorganic salt, preferably ammonium salt, and an acid for etching the fibres to the material to permit penetration of the solution into the said fibres. With the composition of the invention a high strength mechanical bond is apparently formed between the inorganic salt which imparts the flame retardancy and the fibres of the textile material and there is no reliance of any chemical bonding with all the uncertainty which attaches to that.
Description
This invention relates to a flame retardant composition particularly but not exclusively for the treatment of textile materials such as knitted or woven fabrics or synthetic fibres or of blends thereof and carpets ot similar compositions.
For some time it has been recognised that the +lammability of textile materials and carpets represents a hazard.
Textile materials, particularly those used in homes such as furnishing fabrics and upholstery, are likely to be contacted with a +lame, for example from, a cooking stove, fire, cigarette or the like. Many fabrics, particularly those of synthetic fibres will readily combust. Serious and even fatal consequences have resulted from ignition of fabrics particularly in domestic environments.
n number of proposals have been made for dealing with this problem. One of these consists of treatment of textile fabric with a solution of flame retardant compound.
usually an aqueous solution of an inorganic salt followed by drying. Whilst this treatment does impart good flame retardancy, normal wear, scuffing, brushing, vacuum cleaning can reduce and remove the the +lame retardant from the fabric so that the flame retardency can often diminish with time. It is believed that the reason for this impermanence is that the flame retardent solution only penetrates the interstices between the fibres storming the fabric. after drying the flame retardant compound is le+t as deposit on the fibres of the fabric but there is little or no bonding of the flame retardent compound with the textile fabric. Handling of the treated fabric will
often readily dislodge the flame retardant compound
from the fabric with the result that the fabric will have
lost its flame retardancy. For example the drawing of
curtains can shake the flame retardant from the fabric.
Where the fabric that has been treated is a carpet, cleansing the carpet with a vacuum cleaner can remove the
flame retardant. This can be particularly serious if there
is no realisation of the loss of flame retardant
properties.
attempts have been made to provide for bonding between the
flame retardant composition and the textile fabric. Whilst
some success in this direction has been achieved it is difficult, if not impossible, to provide a composition
that will form a chemical bond with all different kinds of
fibres, particularly the synthetic polymeric fibres
which are highly inert.
The present invention has been made with this problem in
mind.
According to the invention there is provided a flame
retardant composition for textile material and carpets
comprising an aqueous solution of inorganic salt,
preferably an ammonium salt, and an acid for etching
the fibres to the material to permit penetration of
the solution into the said fibres.
With the composition of the invention a high strength
mechanical bond is apparently formed between the inorganic '.0 salt which imparts the flame retardancy and the fibres of of the textile material and there is no reliance of v chemical bonding with all the uncertainty which attaches
to that.
It is known to include in flame retardent compositions a
compound which will fluoresce with ultra violet light.
This enables the presence of flame retardant compound to be
assessed by scanning the fabric with ultra violet
radiation. According to a preferred embodiment of the
present invention an ultra violet fluorescent compound is also included in the flame retardent composition. Thus
the pretence of flame retarded can be demonstrated for
fabrics treated with the composition of the invention.
yiny of the known ultra violet fluorescent compounds can be
used in the composition of the present invention.
Preferred ultra violet fluorescent compounds are
those which are water soluble and which do not
discolour or fade the fabric that is being treated.
Many fabrics are provided with a stainproof or soil repellent treatment. As a result it may be difficult if not impossible to penetrate the fabric with a flame retardant composition. The present invention, therefore proposes to include in the composition a surfactant which enables the composition to penetrate the fabric. Preferred surfactants are non-ionic surfactants such as an alcohol ethoxylate.
The acid used to obtain etching of the fibres is preferably a mineral acid. Particularly preferred is sulphuric acid. The concentration of sulphuric acid present in the composition is preferably 0.4 to 0.6%. An at excess of acid should be avoided since that may have a deleterious e++ect on the textile material. Conversely insufficient acid ma not provide adequate etching of the fibre ot the fabric being treated to enable a bond with the composition of the invention to be formed.
The inorganic compounds that provide flame retardancy are preferably ammonium compounds, particularly ammonium phosphates, ammonium bromide, ammonium sulphate and mixtures thereof. The amount of flame retardent compound or compounds that is necessary in order to impart flame retardance to textile fabrics is now well known and is in the order of 12 to 2t:)% by weight of the total composition.
An important constituent of the composition of the invention is a corrosion inhibitor such as benzotriazole.
In many applications fabric treated with the composition of the invention may in use be in contact with metal. It is therefore necessary to ensure that there should be no corrosion initiated or promoted by the treated fabric. The preferred corrosion inhibitor is one which does not discolour the treated fabric.
The composition of the invention may also include additives such as, inter alia, hydrotopes, compounds to retain the ultra violet fluorescent compound, +fragrances and compounds to aid impregnation of the +fabrics being treated. The latter may be required if the fabric has been pre-treated to give it stain proof properties.
The treatment of fabric or other material with the composition of the invention is substantially the same as treatment using known flame retardant compositions. Thus the material to be treated is coated with the composition, +or example by spraying or padding or dipping so that the composition impregnates the fabric. The composition can be applied to fabric in situ, such as furniture, curtains, carpets, upholstery and the like or it can be applied to fabric or other material before being made up into product although the invention has been described largely in
connection with textile fabric it is understood that the composition of the invention may be applied to other
fibrous material such as paper and wood.
The following Eample further illustrates the invention.

The composition was tested on a range of textile fabrics for compliance with the requirements of British
Standards 585 and 5867 and achieved a type 8 classification in each case. Upholstered furniture +abric treated with the composition was tested under British
Standards 5867, 479, 476, 5852 and 5651 and under the
Furniture and Furnishing Safety Regulation 1988 (as amended in 1989). The products achieved classification P5 with the ignition source 5.
A foam backed carpet treated with the composition was tested in accordance with British Standard 479:1988 and achieved a "Low" class which is a satisfactory performance.
In addition the composition has been tested and passed, for flame resistance under, and passed, the C Specification No.8 Issue 2 Flame Resistance Vertical Fabric
Test.
The composition has also passed tests made in accordance with other standards as follows:- 1) Welephant Enterprises Limited a National Fire Safety
Charity in a letter dated 11th September dispatched
to THE HOME BRIGADE being the organisation applying
the product in the United kingdom under the product
name FIREGUARD 2000 FIRE INHIBITOR stated " The

strict accordance with the company's guidelines and
maintained, will contribute to the prevention of fire
and the protection of life and property".
