...process was developed by a St. Paul inventor named Jose Baraquiel Calva, onetime Mexican government engineer. By treating fibers with several chemicals, including cresol, alcohol, benzol and hydrochloric acid, he converts them into a resinous plastic. The fibers can then be stiffened or softened, straightened or curled, made mothproof, shrinkproof, even waterproof...
...Government chemists named Stephen P. Gould and Earl O. Whittier. They produced the fiber by a method similar to that used in making rayon from cellulose. The finished product is straw-colored, resembles the best grade, washed and carded Merino wool, but will not shrink so much and is mothproof. By varying the acids used in curdling the milk they claim they can make a soft, silky grade or a hard, stronger type of yarn. Although Messrs. Gould and Whittier do not know exactly what it will cost to produce synthetic wool commercially, they are certain it can be sold...
...forced through spinnerets like macaroni, passed through a hardening chemical bath, cut into fibres of any desired length. From 100 pounds of skim milk come 3.7 pounds of casein which converts to the same weight of lanital.* Readily dyed, it can be distinguished from wool only by experts, is mothproof...
...chestnut worms, eat furs, feathers and wool, spin translucent tubes in which they spend most of their time. They also spin webs on their feeding grounds, and, finally, cocoons from which the moths emerge. They may be inactivated by naphthalene in flakes or moth balls, sunlight, air, cedar chests, mothproof paper bags, temperatures below 40°. Under the Federal Insecticide Act it is a crime to sell (in interstate commerce) anti-moth products which do not live up to their claims. Last month the Food & Drug Administration had fines imposed on a Chicago chemical company for shipping 1) moth-proofing...
