Blending of comber noil and raw wool and its effect on blanket properties

An exploratory research was carried out to examine the effects of blending comber noil with raw wool on the properties of woollen blanket. Four types of blankets were prepared by keeping comber noil levels at 10, 20, 30 and 40% with Bharat Merino and Chokla raw wool in the blends. Yarn realization and yarn breaking load decreased (P<0.05) with increasing in noil in blends. Thickness of blanket and bending length of warp and weft increased significantly (P<0.05) with the addition of noil. Increase in noil in the blend ratio did not affect the abrasion loss. Dynamic friction coefficient got reduced (P<0.05) with the addition of noil in the blend ratio. Thermal resistance progressively increased with increase in noil in blend ratio and the maximum smoothness was observed on maximum noil percentage. The sensation of coldness and warmth (qmax) was improved with addition of noil. It was concluded that 30% comber noil can be added with fine and medium wool to get good thermal and smoothness properties of woollen blanket.
