Abstract
Sizing is an inherent part of weaving works, consisting in the coating of the warp yarn with a polymeric adhesive, such as starch, in order to assist efficient weaving. The study is aimed to assess the effects of squeezed roller pressure, dryer temperature, yarn count, machine speed (rpm) on cotton fabric weaving. Coarser and finer cotton yarn samples were prepared using sizing solution BENSIZE 850. Different size box temperature, yarn count, fabric construction, machine speed, squeeze roller pressure were considered to construct different weaving designs to study yarn breakages parameter. A warping plan was designed on TAROKO V5.4 (190325) software. The results established that size box lower temperature and higher machine speed provide the smallest amount yarn break during weaving for coarser cotton yarn and the highest for finer cotton yarn. Size box higher temperature and lower machine speed provide maximum yarn breakage during weaving coarser cotton yarn and minimum for fine yarn. Size penetration is uniform, which provides a higher strength of the yarn to less breakage. This aspect of the research suggested that higher yarn strength gives a lesser amount of breakage.
Highlights
Woven fabrics are the ancient and most aristocratic means of wearing and sizing that is a mandatory process for warp yarn before weaving in order to increase the strength of the yarn
Weaving efficiency depends on the sizing parameters such as squeeze roller pressure, size box temperature, machine speed, yarn count, size materials, take-up percentage, viscosity, dryer temperature, substantial content percentage, total ends
Size box temperature is the temperature of sized liquor, which varies according to yarn count and size material wise
Summary
Woven fabrics are the ancient and most aristocratic means of wearing and sizing that is a mandatory process for warp yarn before weaving in order to increase the strength of the yarn. Weaving efficiency depends on the sizing parameters such as squeeze roller pressure, size box temperature, machine speed, yarn count, size materials, take-up percentage, viscosity, dryer temperature, substantial content percentage, total ends. Yarn count, fabric construction, machine speed, squeeze roller pressure were considered to construct different weaving designs to study yarn breakages parameter. Squeezing pressure plays a vital role in applying uniform coating of size paste, the amount of sized material absorbed by the yarn will depend on the squeeze roller pressure It varies depending on the count of the warp yarn. The study shows the effect of controllable parameters on sizing efficiencies, such as squeezed roller pressure, size box temperature, machine speed, yarn coarseness and fineness
