ducing the infiammabilityof fabricsmade of vegetable materials such as cotton, jute or flax and is particularly concerned with cotton' fabrics which have a nap surface, such as flannelette. One objection to the use of fabrics of this character is the fact that a spark or fiamestriking the surface of the goods, even for a very brief instant, is liable to set fire to the nap, and the fire so started flashes quickly over the surface of the cloth. Thus there is. great dangerthat fire catch- "ing in garments made of material of this character will result in burning-the wearer very seriously, even though. the fire originated in a manner which would be entirely harmless if the arment were made or a difierent' materia lln'order to overcome this difgiculty attempts have been made heretofore o treat fabpics of this character in a manner designed to render them permanently less inflammable.
, character are frequently termed in the trade flash-proofing processes and they will be 1 so designated hereinafter.
- The present inventlon aims to devise a process of flash-proofing fabrics which can be economically practised on a commercial scale and which will give superlor results. According to the present process the flan- I nelette or other fabric to. be flash-proofed is first immersed in an aqueous solution of a salt of a metal (other than the alkalme earths) whose hosphate is insoluble. Pref erably we use a uminium sulphate. -Any desired strength of solution can 'beused, say, for instance, about 1 perment.v After the fabric has'become thoroughlywet with the solution it is removed from this bat and the surplus solution is squeezed out .o it by running it throu h a suitable wringer or mangle. The clot is next'iersed in 'an Processes of this thus precipitated on the Application an @ctober 1a. rem. Serial no. 331.1055.
aqueous solution of some soluble phosphate, preferably a sodium phosphate. This solutlon may be of any suitable strength, say, 1 to 2 per cent. The cloth is then wrung out of the second solution, is washed, and dried.
We believe that this process is essentially a process of dyeing with colorless dye. That is, amordant in the commonly accepted sense of the term is a compound with an affinity for textile fibres on the one hand and for certain specific dye stufis on the other.
The fibre is treated first with a mordant,
combination ensuing. The combination of fibre and mordant is then treated with a dye stufi', the dye stufi' whichotherwise would not combine with the'fibre, now combining with the mordant fixed to the fibre, produc v ing a'permanent combination. in the same way aluminium, sulphate, while not ordinarily considered a mordant for cotton because its aflinit aflinity f r the animal fibres, wool and silk, does, nevertheless, combine with cotton; when so combined it will then combine with phosphate ion, thereby fixing the phosphate radical to the cotton in exactly the way a -mordant fixes a dye to the fibre and securing thereby a result not otherwise obtainable. In other words, the reactions that take place in this process are of the same nature as those that characterize any dyeing process using a mordant.
Thatthe result is not-due solely to the precipitation of an insoluble; compound for cotton is so muchless than-its within the voids of the fibre itself, is proven by the fact that barium phosphate and similar insoluble compounds fibre are not permanently affix'ed; they are readily dusted out, whereas the aluminium phosphate is held with great tenacity.
In the process above described the aluminium phosphate is the material that actually does the flash-proofing, but this material is incorporated with the cloth in such away tvgat it remains permanently in the goods.
e have found it impossible to obtain this result simply by mechanically padding or loading the fabric phate. It is evident, therefore, that some thing more than "a mechanical union be tween the aluminium phosphate and the fabrio is produced-by this process.
sulphate, calcium tlll Illlll with aluminium phos- While we have hereinbefore named the materials that we prefer to use in practising this process, it is obvious that other materials than those specifically mentioned can be used. Inasmuch as it ordinarily is undesirable to have the flash-proofing process affect the color of the goods, the salt in the first bath should be one that will form acts as a mordant, and the active elements in both solutions being capable of reacting with each other to form in the goods an insoluble salt of one of the phosphoric acids.
What is claimed as new 'is:
1. The process of flash-proofing fabrics which consists in immersing the fabric successively in two solutions, one of aluminium sulphate and the other of sodium phosphate.
2. The process of flash-proofing fabrics which consists in immersing the cloth in a solution of aluminium sulphate, squeezing the surplus solution out of the cloth, next immersing the cloth in a solution of sodium phosphate, and finally washing and drying the 'cloth.
3. The process of flash-proofing fabrics which consists in treating the fabric successively with two solutions, one of said solutions containing a soluble aluminum salt, and the other containing a soluble phosphate.
In testimony whereof we have signed our names to this specification.
