Definitions

• the object of this invention is to provide an economical method of rendering wool permanently crease resistant Without imparting undesirable features to the wool.
• This invention relates to a method of imparting a permanent crease to a wool fabric which comprises applying to the fabric a water solution of an organosilicon compound having on the average per silicon atom of from 1 to 2 inclusive aliphatic hydrocarbon radicals of from 1 to 3 carbon atoms inclusive attached to the silicon through silicon-carbon bond, there being on the average no more than 3 carbon atoms per silicon atom, the remaining valences of the silicon being satisfied by OH groups or SiOSi linkages, said solution containing from .1 to 10 percent by weight of the organosilicon compound based on the weight of the solution and thereafter creasing the fabric under heat and pressure.
• an organosilicon compound having on the average per silicon atom of from 1 to 2 inclusive aliphatic hydrocarbon radicals of from 1 to 3 carbon atoms inclusive attached to the silicon through silicon-carbon bond, there being on the average no more than 3 carbon atoms per silicon atom, the remaining valences of the silicon being satisfied by OH groups or SiOSi linkages, said solution containing
• the treated wool can be first dried and then creased but often it is advantageous to crease the fabric before drying.
• the temperature and pressure applied to the fabric to obtain the crease is not critical and, in general, those obtained by steam irons or in commercial pressing establishments are sufiicient.
• the water solutions employed in this invention are solutions of high hydroxylated silanols or siloxanols in Ice which there is sufficient silicon-bonded hydroxyl groups to maintain the organosilicon compound in solution.
• the structure of these materials is not precisely known but the silyl units can be any having the defined hydrocarbon groups attached thereto such as CH SlE, C3H7SlE,
• the remaining valences of the silicon atoms are essentially all satisfied by OH groups or combinations of OH groups and SiOSi.
• the compositions can be made up of one type organosilicon compound or mixtures of two or more types.
• solutions of this invention are readily prepared by adding the corresponding alkoxy or acyloxy silanes such as dimethyldimethoxysilane or propyltriactoxysilane to water and shaking until a uniform solution is obtained.
• alkoxysilanes When alkoxysilanes are employed it is advantageous to use a small amount of a weak acid such as acetic acid in order to hasten hydrolysis of the alkoxysilane. This decreases the time necessary to obtain a homogeneous solution.
• the treatment of this invention is applicable both to pure wool and to blends of wool with other fabrics.
• the amount of organosilicon compound actually deposited on the wool runs about percent of the amount in the treating solution. Thus, if one employs a solution containing 2 percent by weight organosilicon compound, about 1.7 percent by weight of the organosilicon compound is actually deposited on the wool.
• the solutions can be applied to the fabric in any convenient manner such as by dipping, padding or spraying.
• the garments were worn by individuals and dry cleaned several times by commercial techniques. The crease remained intact for an equivalent of two or three seasons of wear. These tests show that the treatment was successful in giving a permanent crease to the wool.
• Example 2 W001 gabardine and wool flannel fabrics were treated with 2 percent by weight solutions 1 and 2 of Example 1 in the following manner.
• the fabrics were padded at 40 psi. from the aqueous baths.
• the samples were dried 10 minutes at F.
• Three days later the samples were sprayed with tap water, folded and steam pressed one minute to set a crease.
• the samples were placed in an air circu lating oven and dried 30 minutes at 150 F.
• Example 3 The procedure of Example 1 was repeated employing a solution prepared by dissolving two parts by weight ethyltrimethoxysilane in the place of the methyltrimethoxysilane. A permanent crease was obtained.
• Example 4 Equivalent results are obtained when vinyltriacetoxysilane, allyltrimethoxysilane and ethylmethyldimethoxysilane are employed in the procedure of Example 1.
• the method of imparting a permanent crease to a wool fabric which comprises applying to the fabric a water solution of an organosilicon compound selected from the group consisting of highly hydroxylated silanol and siloxanol organosilicon compounds in which there is an average per silicon atom of from 1 to 2 aliphatic hydrocarbon radicals of from 1 to 3 inclusive carbon atoms attached to the silicon through carbon-silicon bonds, there being on the average no more than 3 carbon atoms per silicon, the remaining valences of the silicon atom being satisfied by substituents selected from the group consisting of hydroxyl radicals and oxygen atoms of SiOSi linkages, there being from .1 to percent by weight of said organosilicon compound based on the weight of the solution and thereafter creasing the fabric under heat and pressure.
