History of American textiles : with kindred and auxiliary industries (illustrated) . o speak,the cotton contents of the rag and leaves inits place a carbon residue which is subse-quently dusted out. Before the reclaimer of wool puts his ragsthrough the carbonizing process, they are water solution. This elimination of exces-sive dust and dirt from the rags results inmaking easier the process of carbonizationand reduces the danger of injury to the woolfibre during subsequent agitating general, however, domestic rags are com-paratively clean and are usually not putthrough any preliminary dusting or w^ashingprocess. The process of carbonization hasbeen the object of scientific experiment bysome of the foremost technical minds of theworld. It is essential that the temperatureof the acid used be high enough to destorythe cotton but not high enough to injurethe condition of the w^ool fibre. Variouskinds of rags and the various kinds of pro-ducts anticipated require various kinds oftreatment during carbonization, so far asconcerns the strength of solution and the. Coolidge Mill of the Amoskaag Manufacturing Company carefully examined. The fastidiousness ofthis examination depends on the accuracyof quality required in the ultimate a carelessness of sorting in theplants of the rag-graders allows the slippingin of color shades too dark or fabrics toocoarse. These uneven pieces can be elimin-ated only by careful inspection. One of thediscrepancies that must be carefully guardedagainst is the presence of any piece of fab-ric containing silk threads. Silk, being com-posed of animal matter, is not attacked bythe acid, and its presence is subsequentlyrevealed in an unsatisfactory manner by itsfailure to accept the dye identically withwool. In some countries where rags are collectedfrom remote districts it has been found apolicy of economy to give them a dustingIsefore they are placed in the acid are even known where they are firstsubjecte
