Investigation of the Comfort and Quality Properties of Knitted Garments Produced with Raised Yarn

The raising process is a finishing treatment applied to textile surfaces to impart softness and bulkiness. Traditionally performed on fabrics, this process creates a fluffy structure by pulling fiber ends to the surface, resulting in a fuller handle and enhanced comfort. In recent years, the adaptation of this technique to yarn form, known as the “yarn-level raising process,” has emerged as an innovative approach in textile manufacturing. When applied to yarns, the process generates a micro-level hairiness on fiber surfaces, increasing yarn volume and heat retention capacity. Consequently, fabrics knitted from such yarns exhibit higher air-holding capacity, lower thermal conductivity, and improved moisture management, leading to enhanced tactile softness and overall thermal comfort. This study aims to investigate the effects of the yarn-level raising process on the thermal comfort performance of knitted garments. In today’s textile industry, the demand for comfort-oriented products—particularly those providing thermal comfort—has been steadily increasing. Although knitted fabrics offer advantages such as flexibility, lightness, and softness, their thermal insulation and moisture transfer capacities remain limited and require improvement. Within the scope of this research, process parameters including fiber type, fiber fineness (nm), and feed rate (m/min) will be examined. Their influence on key performance criteria such as thermal conductivity, air permeability, and moisture transfer will be experimentally analyzed. All tests will be conducted using internationally recognized standard methods. The findings are expected to contribute to the development of comfort- and quality-oriented process strategies in knitted garment production and to scientifically demonstrate the potential of yarn-level raising as an effective method to enhance thermal comfort and moisture management in textile materials.
