.In ordinary laundering} operations the goods are given a bath in which are intro duced; ableach, soap, and an alkali, these agents serving particularlyto remove stains.
5 After such a bath the goods are ordinarily rinsed very thoroughly and in' several suc-.
cessive waters to' remove the alkali. 'Such'i removal is important m order to prevent a coloration and has other points of advantage v referred to hereinafter in detail.
A specific example of a process utilizing my invention is the following The goods are first given a bath in cold water with soap and trisodium phosphate or other softener which reduces the surface tension .of the water'.
so The goods are then subjected to a second bath of hot water (say 118 degrees F.) andsoap serving chiefly for the removal of dirt. .They are then subjected to a third bath containing a bleach, such as hypochlorite i such .as
sodium carbonate. The principal purpose of this bath is'to remove stains. It is used also'toassist in. getting any soapout of .the' goods and into solution in the water. f
The next stage of the process is a succession of rinses, Usually this'has been four successive rinses in'clearwater, for-the purpoes of getting out the alkali and the bleach.
According to my process, one or more cs'of these rinsing operations after applicationof the bleach and alkali, I ropose mstead of trying toget all'thea ali out by:
Ynerely rinsing with water as a solvent,- to
modify the alkali theaddition of an agent 40 which will convert it into a-harmless and easily removed substance. v
For example; I.-add amnionium'sulfate or chloride. or other salt of ammonium. There are also var ous equivalents for ammonium salts in this operation, such for example as Application flea Jun 11,1923. Serial 1101044518.
what are known as substituted ammoniumsalts. Using. ammonium chloride, the combination with-thesodium carbonate will be in accordance with the following' formula 2NH' Cl'-l-Na CO5= 1 Y 2NHg+CO +2NaCl+Il O The ammonia is much less alkaline than sodiumcarbonate and other usual laundry alkalies; or it escapes as a gas. The carbon 56 dioxide of course is agas. ,Thesodium'chloride passes easily into solution and is'neu tral. Thus there is nothin left which, like tlfieoriginal alkali, might 'velop a spot in t e .7
After the rinsing operations described the laundering operations may be continued by a fifth step --in which the goods are subjected to a souring and bluing bath. Finally they aresubject-ed to hot and cold rinsing. As an alternative to the above process, after- 4 -the-bleach and alkali bath I propose to introduce into one or moreof the rinse waters an antichlor such for example as sodium sulfite, sodium bisulfite or sodium thiosulfate 7o 'or some other salt or salts which are reducing to chlorine in an alkaline solution.
Or I may "add such a chlorine reducing agent 'and thelalkali-modifying 4 salt in the.
same rinse water." fact'in order to secure the two effects referred to {I may use an agentwhichcombines them." For ex-Q ample ammonium sulfite or 'ammonium-thio sulfate will serve 'not .only as an aritichlor.
but also as'. a modifying agent for the sodium carbonate or other'alkalir This use of an agent which combines the two efiects referred tois not claimed specifically in the present application, being covered m aj 'divisional application No. (42,268lf.
Another alternative is in the use of the f sodium carbonatesifi one or more of the succeeding rinse operations, in" combination/1 with the antichlpi'. 'me hod, as well as in the method first dw goods. 60
In. this alternativ scribed, it will' be -understood that there are'many known alka'lies which are the Q equivalent of sodium carbonate in thiswork and also a variety of known'anti'chlors; and 5 any knownor suitable agents a-fy be substituted for those specificall re erred .to. -Where the alkali and the antic or are added together in the rinse water, we will gencr- V all'y,-but not necessarily, omit'the alkali m which, according to. the proces first de-- scribed above, wasadded. with the bleach. Though I have described at particularity of detail certain. embot m ents of my invention, yet it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. Variou's modifications thereof in detailan'd in the order of the steps described-may be made: without departing from the invention as definedin the following claims.
