*4.1.2 Effect of yarn modification on wicking characteristics*


### **4.2 Wicking in fabric**

Fabric with a high and consistent absorbency is desirable in almost every wet finishing procedure and many finished fabrics. The wicking property of materials affects their absorbency. When a fabric is entirely or partially submerged in a liquid, or in touch with a small amount of liquid, such as a drop placed on the fabric, wicking occurs. As a result, capillary penetration of a liquid can occur from either an infinite (unlimited) or a finite (limited) reservoir. Immersion, transplanar wicking and longitudinal wicking are the wicking processes that occur from an infinite reservoir. A drop placed on the cloth surface demonstrates wicking from a restricted reservoir [28]. The places of interlacement between warps and wefts were constantly formed in horizontal and vertical directions as fluid flow split. The horizontal yarns (either warp or weft, depending on the test direction) served as fluid reservoirs to wick further along the vertical yarns [29].
