Description

Section D encompasses technologies and processes related to the production, treatment, and finishing of textiles and paper materials. This includes fiber preparation, yarn and thread manufacturing, weaving, knitting, non-woven fabric production, dyeing, printing, and finishing operations for textile products. The section also covers paper manufacture from pulp, paper treatment, coating, and conversion processes, as well as related machinery and equipment essential to these industries. Adjacent sections address raw material sourcing (Section A covers agriculture and fibers), while downstream applications of textiles and paper are classified elsewhere in the IPC system.
