In roller printing the carpet is first woven in white, and then printed on rollers by a process substantially like that of a perfecting press printing a newspaper in color.
Broadloom carpetings.—Any carpet woven on a wide loom. The term is applied particularly to Wiltons, Axminsters, and plain chenilles.
"Sheen-type" rugs; also known as American orientals.—Any machine-made pile rug which has been chemically washed to soften the colors and give it sheen and luster; made in the Wilton, Axminster and chenille weaves.
LINOLEUM
Because of consistent and attractive advertising by manufacturers, the quality and desirability of linoleum and felt-base floor covering are now taken for granted by consumers, and these floor coverings, once regarded purely as a utility product, are sold chiefly on the basis of their decorative appeal. In order to be well informed on their construction you must get the facts from the manufacturers whose products you handle, as both the materials and processes employed have been somewhat widely changed in recent years.
The old method of making linoleum involved the production of solidified linseed oil and its reduction by heat and the admixture of resinous gums to a rubberlike mass known as cement, which was then ground up with cork dust, wood flour, whiting, and pigment to form the "linoleum material." In plain and printed linoleums this material was then calendered on the canvas by heavy heated rollers and seasoned in the drying rooms from 2 to 60 days in temperatures of from 90° to 170°. Granites, jaspes, and cork carpets were made by almost the same process. In making inlays the colored linoleum materials were formed into patterns by one of several hand or machine processes.
In recent years progress has been made toward the partial substitution of linseed oil by a nitrocellulose base in the preparation of the cement. In addition, much linoleum now has a surface coat of nitrocellulose composition, which gives it a glossy surface practically non-markable and highly resistant to strong soaps and soda.
Felt-base floor covering has a printed pattern on a base of felt impregnated with a base of bituminous composition.
CARE OF LINOLEUM
Most linoleum used in homes is manufactured with a lustrous surface which can be maintained with little effort.
