1 Scope
This part of GB/T 23319 specifies procedures to measure the spirality or torque of woven and knitted garments after laundering.
The results obtained from different procedures may not be comparable.
This part of GB/T 23319 is not intended to measure the spirality of garments as manufactured, but rather the spirality after laundering.
Note: some fabric constructions, such as denim, may have spirality intentionally introduced during manufacturing. Garments made of fabrics from circular knitting machines may have inherent nonverticality of wale alignment.
