Sample of carded Peruvian moderate rough cotton fiber; Wonalancet Co., NH; 1913. CARDED MODERATE ROUGH PERUVIAN COTTON. Machined after carding and prepared for the use of woolen and worsted mills. It is rather difficult to tell the difference between carded full rough and carded moderate rough Peruvian cottons except by feel and a slight difference in staple. Such cottons when carded are worth more than many wools. Their presense in clothing can not be detected except by chemical analysis. They serve a very essential purpose and are entirely fit stocks to be mixed with wool in every way. Principally used in flannels, blankets, and worsted yarns. [per 1913 Accession folder information]
The cost and long supply chain of wool imports into the US (which did not produce enough wool to meet domestic demand during the heyday of the American woolen industry) led manufacturers to explore substitutes and additives. Specific strains of Peruvian and Chinese cotton were exploited for this purpose, as being "wool-like" in staple length and feel.
The Wonalancet Co. was incorporated in 1905 by Harry Harmon Blunt in Nashua, NH. The company imported cotton from Piura and Lima, Peru, and from China; it was in existence at least into the mid 1970s.
