Definitions

• This invention relates to a process for finishing cellulose materials. More particularly it relates to an anticrease finishing which is resistant to chlorine by applying dimethylol-imidazolidone-2 together with ethers derived from dimethylol-imidazolidone-Z.
• the present invention also relates to a novel composition of matter which is suitable for use in anti-crease finishing of cellulose fabrics.
• dimethylol-imidazolidone-Z in the presence of suitable acid-forming agents imparts an excellent crease resistance to fabrics consisting of cellulose fibers, in particular to cotton.
• finishes of dimethylol-imidazolidone-2 present a chlorine retaining power owing to the content of nitrogen, especially in those cases where, during the finishing of the fabrics, the condensation was carried out below 150.
• the chlorine retaining power has detrimental effects in that the fabrics thus finished assume a yellow discoloration and lose their strength when subjected, after intense washing, to chlorine treatment and heating (ironing).
• aminotriazine formaldehyde resins accordinging to US. patent specifications No. 2,690,404 and U.S. 2,833,674
• polymeriza-ble vinyl or vinylidene compounds together with a compound copolymerizable therewith accordinging to US. patent specification No. 2,755,198
• the finishings so obtained do no longer exhibit the soft feel and the high respiratory activity of the non-finished fabric which is due to the resinous nature of the additives as above mentioned.
• the ratio between dimethylol-imidazolidone-2 and its ether may range from 9560% to 540%, whereby the impregnating liquors may contain 20 to 100 grams of the mixture per liter solution. Concentration and conditions of application may be controlled to provide 1 t0 7% pick-up of the impregnating agents on the weight of the fabric.
• the ethers of the dimethylol-imidazolidone-2 which may be used under this invention are in particular those being soluble in water, such as the methyl-, propylo1 ethylene-glycol-ether.
• the ethers of the dimethylolimidazolidone-2 containing unsaturated alcohols, such as 'allyl alcohol which are soluble in the impregnating baths exhibit a particularly favorable action.
• Even ethers which contain higher alcohols, such as butyl alcohol, and are insoluble in the impregnating liquors may be employed.
• the water-insoluble ethers have to be admixed, in form of an emulsion, to the solution containing the dimethylol-imidazolidone-2 during the impregnation of the fabric.
• Example 1 A bleached and mercerized fabric consisting of a cotton poplin mixed fabric is impregnated on the padding machine with an aqueous solution of:
• the pick-up of liquor is on the weight of the airdried fabric. Subsequently, the fabric is dried at temperatures of 6080 and afterheated at during 3 minutes.
• the finished fabric cutting is boiled out at first in distilled water for 3 minutes and treated at 27 for 15 minutes in the wetted state with a sodium hypochlorite solution containing 0.25% active chlorine in the liquor ratio 1:50. Then the chlorinated sample is rinsed in fresh water for one minute at a temperature of 2l27, afterwards the excess water being squeezed by hand and this rinsing process being repeated 6 times. Subsequently, the sample is dried in the drying oven at 80 and suspended for 4 hours in an air-conditioned test room possessing a temperature of 20 and a relative dampness of 65%.
• the finished sample is heated for 30 seconds with an ironing press, the metal plate of which is heated to To make comparisons as to the deterioration of the fiber during the heating process that is caused by the effects of the chlorine retaining power are effected as described above.
• dially ether of the dimethylol-imidazolidone-2 utilized in the above example may be prepared as :follows:
• Example 2 A cotton fabric treated with caustic soda and bleached is finished with an aqueous solution consisting of:
• the bis-glycol-dimethylol-imidazolidone-2 which is used in the above example may be prepared in the following manner:
• Rough yield 970 parts of a clear solution of about 50% bis-glycol-dimethylol-imidazolidone-2.
• the raw material may be used straightly for the finish.
• An article of manufacture comprising a cellulosic fabric containing from 1 to 7% of an anti-crease mixture of dimethylol-irnidazolidone-Z and an ether thereof whereby the ratio between dimethylol-imidazolidone-2 and its ether range from -60% to 5-40%.
• a process of anti-crease finishing of cellulosic fabrics which comprises impregnating the fabric with impregnating liquors containing a mixture of dimethylolimidazolidone-Z and ethers thereof whereby the ratio between dimethylol-imidazolidone-2 and its ether ranges from 95-60% to 540% and the impregnating liquors contain 20 to 1 00 grams of the mixture per liter of solution, controlling the concentration and conditions of application to provide 1 to 7% pick-up of the impregnating agents on the weight of the fabric, and fixing the impregnating agents on the fabric by drying and heating the impregnated materials.
