What reading level is Chemistry for Launderers book?
To quickly assess the difficulty of the text, read a short excerpt:
Mercerized cotton has a mnch higher affinity for dyes than ordinary cotton, and this again is a valuable property. Bleached cotton fibres will take a much higher degree of lustre than when unbleached, so that the first step in mercerization is to bleach the hanks of cotton, which, by the way, are selected from the Egyptian or Georgian long-stapled fibre in pre- ference to the short-stapled American product.
After bleaching, the hanks are washed, stretched on rollers, and passed through the merc...erizing solution. There are various modifications of this process, some of which are distinctly injurious to the fibre. The fibres may be injured in the bleach- ing or may be over-stretched in mercerizing, or the bleaching and mercerizing process is sometimes combined to the injury of the fabric. Conse- quently, in many cases, a fabric is produced by mercerizing, which, instead of being stronger than ordinary cotton, is materially weaker, as the launderer knows to his cost.
The Action of Alkalies.
