Excerpt from book: QUANTITATIVE ANALYSIS PART II . Mixed Fabrics In General. Fabrics are made in a variety of grades or qualities in order to meet the varying demands of the consumer. It is a very common thing in textile manufacturing to vary the grade of a fabric for this reason only. This is particularly true in America, where the fabrics must at the same time be cheap and pretty. As a result the manufacturer is compelled to bend the quality to the price instead of being able to command a fair price for a higher grade article. The price is met by making the goods lighter in weight, using poorer yarns, making the cloth narrower, or finally by supplying a deficiency in weight by chemicals called filling materials. A person who thinks he is buying the same fabric for I2.V cents as for 15 cents is as a rule badly mistaken. All wool fabrics, in which the warp lies on the face, are frequently found to contain a fine worsted fiber in the warp and a much cheaper wool or shoddy yarn for filling. India linon contains no flax at all; it is made of combed cotton yarns. Linen mesh underwear has been produced solely from cotton yarns, and cotton-worsteds contain no trace of wool. Goods made of linen and cotton can be finished with a beetle and so made to look like all linen. Then again two mohair fabrics which at a rough glance appearedto be identical were offered at 50 cents and $1.25 per yard. The analysis showed that the first contained 50% cotton, while the second contained 25% of the vegetable fiber. These are but a few of the many examples of falsification, or rather substitution, which serve as illustrations at this point. One flagrant abuse of a term has been observed in recent years in the case of merino. This name was originally applied only to the wool obtained from sheep bearing…
