위편성 핀턱(Pintuck) 조직의 변화에 따른 물성 연구

Abstract

The purpose of this research was to identify the mechanical properties of the several different types of pintuck stitches that were frequently used in knitting industry. Pintuck fabrics were knitted under same knitting conditions, then the mechanical properties including Tightness Factor(TF), tensile strength, elongation, and stiffness were investigated according to the Korean Industry Standards. The experimental results are as follows. 1. The knitting time was more spent with the increase of pintuck courses. 2. The Tightness Factor(TF) was influenced by the value of the loop length, regardless of pintuck courses. On the other hand, the density of loops tended to decrease the CPI and the WPI values as pintuck courses increased. 3. The tensile strength was increased as pintuck courses increased in the course direction. However, the tensile strength was almost constant in the wale direction regardless of pintuck courses. 4. In the elongation measurement, the elongation value was almost constant in both the course and the wale direction regardless of pintuck courses. 5. The stiffness value tended to increase as pintuck courses increased in both the course and the wale direction. It has implications of academicians and industrial personnel who require information for pintuck stitches in weft knitting.
