Definitions

• This invention relates to methods of treating cellulosic materials such as, for example, cotton fabrics and the like.
• One of the objects of the invention is to alter the physical character of woven cellulosic fabrics so as to enhance its appearance andgive to fabrics other than linen an appearance and quality closely resembling linen.
• Another object of the invention is to produce certain novel effects in cellulosic fabrics by a printing or analogous operation in which the appearance and quality of the fabric are physically altered in accordance with a predetermined design or figure.
• 16 still further object of the invention is to produce an improved laminated fabric in which the adhesion of a plurality of plies 0f cellulosic fabric is obtained to such a high degree as-to successfully withstand all ordl- 20 nary handling and treatments, such as laundering, without the plies becoming separated.
• One of the features of the present invention is in the nature of an improvement upon the process therein setforth and it difiers from the aforesaid treatment in that the cellulosic material impregnated with caustic alkali (caustic soda or caustic potash) is allowed to dry before the subsequent treatment with the cuprammonium solution.
• caustic alkali caustic soda or caustic potash
• This drying of the impregnated fabric has the effect of further intensifying the action 7 of the cuprammonium solution so that the alteration of the fabric is intensified.
• caustic of at least 3035 Tw. should be used in this case, as the dried cloth will take up much larger quantities of the copper-ammonia solution, more caustic being required in consequence to activate it.
• the printing method according to the present application embraces the preliminary impregnation of the cellulosic fabric with caustic alkali and the subsequent treatment with cuprammonium solution, with or without previous drying of the caustic-filled fabric.
• the printing method also includes the further feature of the use of a thickened paste of cuprammonium solution, so as to facilitate the application of the cuprammonium to the caustic-prepared fabric in the printing operation.
• the cellulosic material for example cotton fabric, is first impregnated with caustic alkali solution (especially caustic soda or caustic potash) either by padding or by printing, and preferably it is then dried.
• caustic alkali solution especially caustic soda or caustic potash
• the strength of caustic may vary from about 15 'lw. up to mercerizing strength and over, according to the effect desired.
• a satisfactory composition of the printing paste is as follows:
• the cellulosic fabric may, for example, first be lmpregnated with caustic alkali solution such as caustic soda 30-35 Tw.) and then ried. Thereafter the material containing the dried caustic is padded with cuprammomum solution made up of 400 pounds copper sulphate, 150 gallons water, 80 gallons commercial ammonia.
• caustic alkali solution such as caustic soda 30-35 Tw.
• cuprammonium solution upon the fabric contaming the dried caustic is very rapid and a few seconds immersion of the fabric in the cuprammonium solution is sufficient to develop the adhesive qualities, when the plies should be immediately brought together and united by pressure rolls or the like. Thereafter the webs or plies which have been joined together may be passed through the usual tentering machine and thence to the souring and washing operations for the removal of the excess of reagents and the precipitated copper compound produced in the cuprammonium treatment.
• the cloth is soured in d1- lute sulphuric acid of, for example, 6 Tw., washed in copious water and laundered, dried, ironed or calendered, as may be desired.
• the duration of treatment in the cuprammonium bath in any of the processes described may amount to, for example, three to five seconds at ordinary tem eratures.
• T e e ressions natural fibrous material of the. c aracter described and natural cellulosic fabrics of the character described are employed to indicate the well known vegetable fibres such as cotton, jute, linen, ramie and wood, but to exclude esters of cellulose such as the well known'artificial silks and the like.
