I The present invention relatesto the iodiz'ation oftextile fabrics. i
It 'isan object of the present invention to provide aprocess for impregnating all kind of textile fabrics with any fixed dose of free and active iodine, and in such a manner that the impregnated fabric give of! substantially its full content of free andactive iodine when the impregnated other suitable liquid.
;It is another object toprevent the iodine from:
. affecting substantially thetextil e tissues.-
It is still another object to protect the active iodine from-decomposition and atmospheric influences.
It is a further object to preserve the hydrophile qualities of the impregnated fabric.
The impregnated fabric according to this invention is particularly useful for surgical purposes since the material can be kept sterilized and dry. When put on a wound it gives 01! active iodine as soon as it is moistened by thesecretion of the wound. Alternatively, by soaking the impregnated material in water or any other suitable liquid it is possible to obtain a solution of iodine which may be used for surgical purposes.
According to the invention the textile fabric is impregnated with isinglass and iodine. Sugar and glycerine may be added. Experiments have shown that the fabric impregnated according to the invention is able to be stored for a considerable time without losing its advantageous qualities. A possible explanation for this result seems to be that the isinglass protects the tissues of the fabric against being affected by the iodine while the sugar and glycerine act as an adhesive. The process of impregnating the fabric according to this invention may comprise the following steps:
(1) The textile fabric is freed from any dressings or hot pressing ingredients by washing and/or boiling in the usual way.
wateror in machine, about 20 per cent of the solution.
(2) When dry and if the impregnated fabric is 7 used for surgical purposes it is sterilized by means of saturated steam at high temperature.
(3) The fabric is immersed in a solution of water (H2O), sugar (Cal-121011), glycerine CaI-IMOH) 3) (6) The material is allowed to l (7) The process No. 5 is repeated, but the aqueous solution of iodine contains-nowan, ad-
mixture'of alcohol and sugar.

' '2 gms. of purified isinglass as used for medicinal w purposes are mixed with 100 gins. of water. The mixture is left swelling up for about 24 hours. It is then slowly heated on a water bath to about 60 C. while it is permanently stirred. When the isinglass is completely dissolved, the solution is filtered. To the filtered solution 0.024 gm. of glycerine and 0.05 gm. of sugar (CizHnOn) are added. Subsequently, the solution is, again, well stirred.
The textile fabric is immersed in the solution thus prepared until it is saturated. The temperature ofthe solution should be kept during this step at at least about 50 C.
The fabric is then passedrthrough a wringing machine so that it contains, after passing the Subsequently the material is thoroughly dried in any known manner.
The fabric is then passed through a first aqueous solution of iodine. The percentage of iodine is chosen according to requirements. A 4 to 4.5 per cent iodine solution meets normally almost all requirements. The solution may consist 012 gms. resublimed iodine; 4 gms. potassium iodide and 50 gmsl distilled water. The fabric is immersed in the solution until it is saturated, and is then passed through a wringing machine so that it contains after passing the machine about 20 per cent of the solution. The metal parts of the wringing machine are preferably protected by a coating of an acid resisting lacquer.
The fabric is now thoroughly dried in a drying chamber. having a good air ventilation at a temperature between about 18 and- 25 C. During during which time it should be protected against light, moisture and heat.

The temperature of this second solution should be at The fabric is then passed through a second least 15 C. The fabric is not saturated with v the second solution but is passed quickly there through and is thereupon at once passed through a wringing machine so that it contains finally ,about 5% of the solution. It is then again dried as before. For storagev the impregnated material is well packed in a suitable packing material. For normal climates it is sufficient to wrap, the material in waxed paper and 'in addition in thick, dark packaging paper and to store itat a dry place. For tropical climates the waxed paper is replaced by plasticized polyvinyl.
