Definitions
- This invention relates to improvements in the mechanical finishing of textiles, and is more particularly concerned with improvements in the production of washfast effects on fabrics consisting wholly or substantially of regenerated cellulose.
- the object of the present invention is to solve the above problem.
- a process for fixing mechanical efifects and finishes on textile fabrics consisting 2,820,715 Patented Jan. 21, 1958 wholly or substantially of regenerated cellulose, comprises impregnating the fabric with an aqueous solution containing a water soluble lower alkyl ether of dimethylol urea having a minimum etherification of of all the methylol groups present, and an acid or potentially acid curing agent therefor, mangling or otherwise expressing surplus solution from the impregnated fabric, at least partially drying the fabric, subjecting the fabric to the desired mechanical finishing treatment, and heating the fabric to insolubilize the impregnant.
- regenerated cellulose we intend to include, inter alia, spun viscose, viscose staple-fibre, viscose continuousfilament yarn and Bemberg or cuprammonium-cellulose yarn.
- the solution may contain in addition to the ether of dimethylol urea a lower alkyl ether of a methylol melamine in an amount not greater than the amount of the ether of dimethylol urea.
- the methylol melamine contains two or more equivalents of formaldehyde.
- the material After impregnation the material has the surplus solution expressed by mangling or other suitable process so that between 5 and 25% of the ether or ethers based on the weight of the fabric is retained thereon before drying.
- the fabric is then dried with the avoidance of excessive tension and stretch.
- Mechanical effects which may be fixed are for example of glazing, embossing and schreinering.
- the preferred ethers are the methyl, ethyl and propyl ethers of dimethylol urea and of methylolmelamines containing two or more equivalents of formaldehyde.
- the methyl ethers are those generally preferred. In the practice of the invention it is not essential that these ethers be chemically pure entities. Technical products have been found to give quite satisfactory results. Nor is it necessary to isolate these ethers, which are crystalline compounds, in crystalline form.
- Solutions comprising the alkylated products obtained by reaction of the amino-methylol compounds with the appropriate alcohol may equally well be used, preferably after concentration and recovery of excess alcohol for re-use, but in the use of technical products so described care should be exercised to ensure that the highest possible degree of alkylation has been obtaind. Partial alkylation only of the methylol groups present will enhance the watersolubility of themethylol compounds to a mis-leading extent, but the products will be generally less satisfactory since the unconverted methylol groups tend generally towards premature resinificaticn, giving rise inevitably to processing difficulties and harshness of handle in the textile applications.
- Natural-fibre fabrics such as cotton goods have already a firmer handle and respond less critically to synthetic resin modification. That is to say, the material and methods of the prior art, which have been designed successfully but primarily for the treatment of natural-fibre fabrics such as cotton and linen, have proved unacceptable when applied to regen erated cellulose, in that the synthetic resin ingredients hitherto used are generally too reactive at too early a stage of the impregnation and drying processes involved, and.
- the methylation of the methyl etherof dimethylolurea used in Examples 1, 3, 4, 7, 8, 9, 10 and 11 was 87 percent of that theoretically possible. That is to say, the percentage of the methoxy groups as determined by the Zeisel method was 36.5 percent, whereas that in a pure dimethyl ether is 41.9 percent.
- the ethers used in 15.x amples 2, 5 and 6 Were laboratory preparations and, it is difiicult to determine accurately the degree of etherification of vthese ethers but it is at least percent.
- Example 1 Viscose rayon staple fabric. (Utility 1005) was impregnated with a solution containing 8.5 percent of the dimethyl ether of dimethylol urea and.0.17 percent of ammonium thiocyanate. The fabric ,was squeezed between heated, .embossedmetalsurface so that a pattern in A? relief was obtained, the temperature during this process being about 130 C. The embossed fabric wasthen heated for 10 minutes at 140 C. to effect a finalicu're of the resin-formed. The handle of .the embossedfabric was excellent and on Washing for 10 minutes in 0.5% nap; at C., the embossed pattern was unaffected.
- Example 2 i A similar fabric was treated with a solution containing 5% of the diethyl ether of dimethylol urea'i and 'O.1%jL
- Example 3 A similar fabric was treated as in Example 1,;but in 7 this case the quantity of the dimethyl etherof dirne'thylol urea was increased so that the treated fabric contained 15% thereof,-the quantity of ammonium thiocyanateem ployed being increased proportionately.
- the procedure of Example .1 was carried out, as beforegwhen the embossed fabric was found to havea good handle and the fastness to washing of the embossed finish was excellent,
- Example 4- A similarfabric was'impregnated with 5% of a mix ture consisting of four parts of the dimethyl ether of dimethylol urea'and one part oftechnical trime'thylrether of..trimethylolymelamine,together with 0.1% "oflarn:
- a similar fabric was impregnated with of the diisopropyl ether of dimethylol urea and 0.2% of ammonium thiocyanate by the method of Example 1 and similarly dried, embossed and cured.
- the handle was excellent and the wash fastness of the embossed pattern was good.
- Example 6 A similar fabric was impregnated with 10% of the di-n-propyl ether of dimethylol urea and 0.2% of ammonium thiocyanate. The ether was not soluble in water at this concentration and of methylated spirits was therefore added to efiect solution. The fabric was dried, embossed and cured as before and a satisfactory washfast embossed finish resulted.
- Example 7 The procedure of Example 1 was repeated on a similar fabric except that the bath contained 0.255% diammonium hydrogen phosphate instead of 0.17% ammonium thiocyanate as catalyst. A satisfactory wash-fast embossed finish was obtained.
- Example 8 A sample of American spun rayon challis having 80 ends and 64 picks per inch was impregnated with 10% of the commercial dimethyl ether of dimethylol urea and 0.3% of tartaric acid. The fabric was dried, embossed and cured as before and an excellent wash-fast embossed finish was obtained.
- Example 9 300 yards of a printed spun rayon fabric was padded through a solution containing 10% of the commercial dimethyl ether of dimethylol urea, 2% of technical trimethyl ether of trimethylol melamine and 0.188% ammonium thiocyanate.
- the fabric was mangled so that the pick-up was 80% and dried on a stenter so as to leave about 10% residual moisture.
- the dried fabric was passed twice through a glazing calender, the bowls of which were heated to 380 F. and finally cured for 3 /2 minutes at 300 F. A soft, glazed finish fast to washing was obtained.
- Example 10 A sample of American spun rayon challis having 80 ends and 64 picks per inch was impregnated with 10% of the commercial dimethyl ether of dimethylol urea and 0.5 of aluminium sulphate. The fabric was dried, embossed and cured as before and an excellent wash-fast embossed finish was obtained.
- Example 11 Three samples of viscose rayon staple fabric were impregnated with 6% of the commercial dimethyl ether of dimethylol urea and 0.12% of ammonium thiocyanate and dried to various moisture contents as follows:
- Example 12 Two samples of Utility 1005 spun rayon fabric were impregnated with (a) 5% methylated dimethylol urea of methylation (b) 5% methylated dimethylol urea of 60% methylation 0.1% ammonium thiocyanate was also present in each case (a) and (b).
- the sample subjected to treatment (a) showed a good retention of the embossed pattern after washing while the sample subjected to treatment (b) was unsatisfactory.
- a process for fixing mechanical effects on a textile fabric consisting substantially of regenerated cellulose comprising impregnating said fabric with an aqueous solution containing a water soluble C -C alkyl ether of dimethylol urea having a minimum etherification of 75 of all the methylol groups present and a curing agent therefor, expressing surplus solution from said impregnated fabric, at least partially drying said fabric, subjecting said fabric to the desired mechanical finishing treatment and heating said fabric to insolubilise the impregnant.
