Quick Summary

Stuffing refers to soft material used to fill hollow parts of something. In fiber manufacturing, specifically for man-made fibers, "stuffing" describes a process where large bundles of fibers, called tow, are crimped. This is achieved by feeding two tows into a stuffer box, causing them to fold and compress. This compression, often aided by steam heating, sets a zigzag crimp into the filaments. After crimping, the tow is cut into staple lengths and baled for shipment to textile manufacturers. This texturing process affects the fabric's characteristics, such as softness, elasticity, and resilience.12
