Application May 14, 1937, Serial No. 142,623. In .Germany May 19, 1936 .17 Claims.
This invention relates to processes for producing water-repellent textile materials and products therefrom.
The principal object of the present invention is to increase water-repellence in textile material by a simple process; and to produce products having improved characteristics thereby.
The invention accordingly comprises the novel products as well as the novel processes and steps of processes according to which such products aremanufactured, the specific embodiments of which are described hereinafter by way of example and in accordance with which I now prefer to practice the invention.
According to the present invention water-repellence is accomplished by the impregnation of textile with water-soluble quaternary ammonium compounds of methyl halogen ethers of higher fatty alcohols having the general formula Room NX.halogen in which R is an aliphatic radical containing at least carbonatoms, and NX stands for a tertiary amine, with subsequent heating.
As tertiary amines used for the formation of the quaternary ammonium salts those tertiary amines are used which are sufficiently volatile, in order that they may volatilize off during the subsequent treatment. There may be advantageous- 1y employed the heterocyclic bases which contain a tertiary nitrogen atom in the ring such as pyridine, quinoline and isoquinoline or homologues or substitution products thereof. There may also be employed aliphatic tertiary amines such as trimethylamine (CH2) 3N or triethylamine (C2H5) 3N.
There may also be employed the quaternary ammonium salts of methyl-halogen-thioethers of higher fatty thioalcohols having the general formula:
R.S.CH2
NX.halogcn The quaternary ammonium salts of these ethers are prepared as follows: The halogen ethers are first prepared. For example methyl chloride ether of octadecane is prepared as follows: Dry hydrochloric acid gas is introduced at ordinary temperarature into a mixture containing 2'70 parts of octadecylalcohol, 810 parts of benzol, and 30 parts of trioxymethylene, until the formation of the octadecylchlormethylether occurs which can be clearly recognized by the benzol solution becoming clear. The water from the reaction which accumulates at the bottom of the vessel is run off, the benzol and the surplus hydrochloric acid are removed in a vacuum. The reaction which occurs may be represented by: CH3. (CH2) 16.CH2OH+CH2O+HC1 CH3.(CH2) 1e.CH2.O.CH2.Cl+H2O r The quaternary ammonium salt of the ether, for example with pyridine, is formed in the following manner: 319 parts of the octadecylchlormethylether are stirred with parts ofv pyridine. The mixture solidifies immediately and the quaternary pyridinium salt of octadecylchlormethylether results:
CHa.(CH2)m-CH2.0.CH2
CH3. (CH2) w.CH .O.CH2+HO.cellulose Quaternary pyridiuium salt of octadecylmethyl chloride ether C Ha. (CH2) m. CH2. 0 C Hz .cellu1ose+ +H 01 Quaternary pyridinium salt of hexadecylmethylchloride thiocthcr omrcnmomsom N 0.ccl1ulose+/ +H01 The pyridine formed in the above reaction is volatilized as above stated during the heating to which the textile materials are subjected after reaction, as given for instance in the examples below.
It has been found that textiles, particularly natural or regenerated cellulose, can be rendered water-repellent by treatment with these quaternary ammonium salts of the halogen ethers. The materials herein described are all soluble in water and the treatment may be accordingly carried out in this medium, thereby avoiding the use of expensive organic solvents and recovery apparatus therefor.
The pyridine and other tertiary amines liberated by the reaction of the chemicals on the textile materials treated by the above examples is volatilized when the textile is heated at the temperatures therein mentioned.
Where the context permits the expression ethers as used in the appended claims designates either an ordinary ether or thioether.
The process is also applicable to textiles of animal origin such as wool and silk, etc. as shown for instance in the examples below.
The impregnation of the textile material by the products set forth can be effected in any desired inanner, by immersion of the material to be treated or by spraying it or other like procedure. The impregnation is preferably accomplished at a temperature slightly above that of room temperature, and thereafter upon drying the material is usually heated at a temperature above the drying temperature and in the neighbor hood of 100 C. to affect water-repellence.
The following are examples of the invention as I now prefer to practice it. It is to be understood that these examples are illustrative and that the invention is not limited thereto except as indicated in the appended claims:
Examples 1. Undyed, unbrightened, loose spun viscose rayon is introduced into an aqueous bath heated to about 40 C. containing per liter grams of octadecoxymethyl pyridinium chloride.
C1sHs1. 0. CH2
Ihe spun rayon remains for about 15 minutes in this bath, is then removed, centrifuged and dried at 90 C. After the drying has taken place the spun rayon is preferably heated for several hours at 90 C. The spun rayon which has been treated in this way shows a water-repellence which resists washing with soap and Water and also resists dry-cleaning by benzine. In the presence of soap or other wetting agents the water-repellent material so produced may be dyed hot; after thorough rinsing of the wetting agent or soap the water-repellent effect reappears.
2. A dyed dress material having a warp of cotton and a filling of viscose silk is treated in an aqueous solution of grams per liter of docosoxymethyl pyridinium chloride at a temperature of about C. It is then removed, squeezed and dried at about C. After the drying it is preferably heated for several hours at about 100 C. in a drying chamber. The treated material shows water-repellence which is resistant to dry-cleaning as by benzine and washing with soap.
3. A dyed cloak material made of spun cuprammonium rayon is treated in an aqueous solution of 15 grams per liter of trimethyl octadecoxymethyl ammonium chloride Ngcl at a temperature of about 45 C. It is then removed, squeezed and dried at about C. and after drying is preferably exposed for several hours at a temperature of about C. The resulting material has substantially the same properties as described for materials in Examples 1 and 2.
