A Novel and Comprehensive Final Finishing Process for Worsted and Related Fabrics

Abstract

In conventional processing, handle, thickness, lustre, dimensional stability, etc., are largely determined by the three final finishing processes known as pressing (hydraulic or rotary), blowing and high‐temperature decatising (the last being essentially a ‘setting’ process). The significant changes in fabric properties which are brought about in these three industrial procedures are briefly mentioned, and emphasis is given to the results that can be achieved in respect of fabric compression and subsequent recovery. There are serious limitations to the extent to which a high degree of compression can be permanently ‘set’ into fabric when it is in roll form, and also to the permanence of finish that can be achieved by continuous blowing or pressing.The principles underlying the proposed new process are then described. Data are given for the compression and recovery characteristics obtained with this process, and these are compared with the results of conventional methods.The paper consists of an account of the development of a machine for industrial production, indicating some of the problems that have had to be solved, and ends with an assessment of its anticipated commercial advantages.
