(GEEK) UNDER THE ACT 0F BGE 3, 1888, A5
This invention described herein may be manufactured and used by or for the Government for governmental purposes without the payment to me of any royalty thereon.
This invention relates to a compound for bleaching textiles such as cotton cloth, wool yarn,rayon cloth and the like, and to novel solutions thereof for bleaching purposes.
It has been found by the applicant that chloroimide of succinic acid, a so known as succinchlorimide, has eficient and advantageous bleaching properties. i
This compound is represented-by the following structural formula:
a The objea pres invention is ta provide a bleaching agenthavin an intensity. of action which is quite 'de 'itely intermediate between the more intense and the less intense bleaching agents heretofore used. Further objects will be apparent from the following description of the invention.
Broadly the invention com rises the bleachv y aqueous solutions of succinchlorimide which may be either acid or alkaline in reaction. The bleaching agents at present employed in the textile industry are of various kinds, such as chlorine gas that may be led into watery solutions giving chlorine water, which Application filed Eebruary 1%, 1932. serial Ho. 592,682.
1 so, 1928; are e. e. 757) this class may be mentioned those of the general type of hydrogen peroxide. that alkaline reaction may be established, which is often necessary in bleaching rocesses, the compound sodium peroxide, a 0
In order and sodium perborate, NaBO are also used in the industry.
Bleaching agents are needed for certain purposes in the textile industry which are less prompt and less intense than are the bleaching agentscontaining chlorine and yet more. active than the-bleaching agents whichjare as slow in their bleachingaction as those of the general type fof hydrogen peroxide or those bleaching proce'sse'swhere alkaline reaction is necessary to beestablished by using compounds such .a'ssodium peroxide, Na O or sodium perborate,-Na BO The new solutions of succinchlorimide' have I been found tohave an intensity for bleaching cotton cloth and the like intermediate between the intensity of the bleaching agents heretofore used.
An acid or alkaline solution of succinchlorimide will also effect bleaching. An aqueous solution of this compound is moderately acid in reaction. There can be added to an solutions certain alkalies the bleaching properties of acid or alkaline solutions of succ1n-, chlorimide bein present in about the same relative intensities. Either the acid or alka line solutions of the succinchlorimide are quite definitely intermediate between the is a rather active bleaching agent; or the? 'more intense bleaching powder and the less chlorine gas may be led into aqueous solutions of sodium carbonate or sodium hydroxtive bleaching agents as they doubtless contain the compound sodium hypochlorite, NaOCl. The chlorine gas may also be allowed to assnover calcium hydroxide with which it reacts, forming chiefly the compound calcium chloro -hypochlorite, ClCaOCl; this product'is incompletely soluble in water and such solutions are active bleaching agents.
For certain uses in the textile industry bleaching agents are employed which are more mild in their bleaching action than any of the chlorine bleaches disclosed above. Of
intense sodium perborate.
It has been found that cotton cloth may be effectively bleached by the use of an aqueous solution containing 3% of succinchlorimide, which is equivalent to about 1.6% available chlorine. Weaker solutions of succinchlorimide may of course be used and in some cases are more advantageous. When an alkaline bleaching solution is desired the addition of one equivalent of an alkaline compound to the solution has been found to be effective. For example: four-tenths grar'n' of sodium carbonate may be added to the solution for each gram of succinchlorimide.
Having described my invention what I wish to secure by Letters Patent is:
1. A method of bleaching textile materials which comprises subjecting the materials to the action of an aqueous solution of succin chlorimide.
5 2. A method of bleaching textilematerials which comprises sub'ecting the materials to the action of an aci solution of succinchlorimide.
3. A method of bleaching textile materials 1 which comprisessubjecting the materials to to the action of an alkaline solution of succinchlorimide.
4. A composition for bleaching textile material consisting of aqueous solutions of suc- 15 cinchlorimide; a 1
5. A composition for bleaching textile material consisting of acid solutions of succinchlorimide.
6. A composition for bleaching textile ma- O-terial consisting of alkaline solutions of succinchlorimide.
