When PVA is used in high proportions or as single component, it creates stiffness in yarn, high abrasions to mechanical parts of weaving machine, high yarn to yarn abrasion, multiple breaks at leasing, skin formation in size box, difficult desizing if used with starch. Some grades of PVA are also known for foaming in saw box. Environment concern also exists for its use. All these issues make use of PVA limited. It is extremely difficult to use.
