Lister invented the Lister nip comb which separated and straightened raw
wool, which has to be done before it can be spun into
worsted yarn, and in the nineteenth century it was a hot, dirty and tiring job. By inventing the nip comb, Lister revolutionised the
industry. Around 1855 he began work to find a way of utilising the fibre contained in
silk waste. The task occupied his time for many years and brought him to the verge of bankruptcy, but at last he succeeded in perfecting silk-
combing appliances which enabled him to make good quality yarn at a low cost. Another important invention in connection with silk manufacture was a
velvet loom patent that he bought in 1867 to the Catalan inventor
Jacint Barrau. The new loom was built at Manningham Mills by
Jaume Reixach, Barrau's foreman and Lister's Mill director afterwards, and made him very rich. However, the business was seriously affected by the prohibitory
duties imposed by the United States, making him an early critic of the British policy of
free trade. == 1891 Manningham Mills Strike ==
