The purpose of the study was to determine the effect of yarn count and courses per inch(CPI) of interlock knitted fabrics on the air permeability and heat transfer properties to provide the basic data for constructing high functional knitted fabrics were produced with excellent comfort. Nine interlock knitted fabrics were produced with different yarn count and stitch density for this stuffy(combination of Ne 30's, 40's, 50's(CM). and CPI of 34. 37, 40). Physical properties of nine knitted fabrics including air permeability and heat transfer properties were measured and analyzed statistically. The results were as follows; 1. Greater stitch density effects rather than yarn count effect on the variation of tile coefficient of surface friction was achieved. Thicker yarn count and lower CPI of knitted fabrics had greater variation of coefficient of surface friction. 2. Finer yarn count of knitted fabrics at constant stitch density and higher density of knitted fabrics at constant yarn count had excellent compressional resilience. 3. Air permeability of knitted fabrics Increased with decreasing thickness, weight and MTV(machine tightness factor) of knitted fabrics and with increasing air content in knitted fabric structure. TIV(thermal insulation values) of knitted fabrics increased with decreasing air permeability of knitted fabrics. Thicker yarn count of knitted fabrics at constant CPI had greater variation of TIV. 4. Warm sensation of knitted fabrics increased with increasing CPI and surface irregularity of knitted fabrics, while cold sensation increased with increasing coefficient of surface friction of knittell fabrics and air content in knitted fabric structure.

The purpose of this study was to determine the effect of yarn count and stitch density(course per inch, CPI) of interlock knitted fabrics on the mechanical properties and hand values(HV) to provide the basic data for constructing high functional knitted fabrics for out wear with excellent handle. Nine interlock knitted fabrics were produced with different yarn count and stitch density for this study(combination of Ne30's, CM40's, CM50's, and CPI of 34,37.40) . Mechanical properties such as tensile, shearing, bendiilg and compressional property of nine knitted fabrics including surface property. thickness & weight were measured by KES-F system on knit condition. The KH-402KT equation was applied to obtain primary HV on the basis of measured the mechanical properties and the KN-301-W equation was applied to obtain total hand values(THV) on the basis of the primary hand values. The experimental results were statistically analyzed to investigate the effects of mechanical properties and HV by knitting condition. The results were as follows : ( 1) Thicker yarn count and stealer stitch density of knitted fabrics showed an abundant shearing elasticity. On the other hand, in the performance of silhouette showing up a curved line of human body. Inner yarn count and lower stitch density of knitted fabrics were profitable. (2) Deformation of elongation at the condition of maximum load 250gf/cm was highly influenced by course density rather than yarn count of knitted fabrics. Higher deformation of elongation in the direction of course(EM-2) and lower bending rigidity(B-2) showed excellent deformation of curved surface with girth of human body. But greater stitch density had excellent dimensional stability. (3) For the purpose of designing knitted fabrics with smooth surface properties. Inner yarn count of knitted fabrics at greater density and thicker yarn count at lower stitch density were adequate. Especially, 30's of knlitting yarn at 34CPI, 40's of knitting yarn at 37CPI. 50's of knitting yarn at 40CPI showed high adeguacy respectively. (4) For the purpose of improving handle of knitted fabrics, koshi at thicker yarn count and greater density, numeri, fukurami at finer yarn count and lower stitch density and THV at Inner yarn count and greater density of knitted fabrics were adequate respectively. (5) A primary factor of mechanical properties contribute to HV of knitted fabrics. roshi had high degree of correlation with bending and shearing properties and numen, fukurami had high degree of correlation with RC, W and so on. The order of HV that contribute to THV was koshi>fukurami>numeri.

This study was conducted to determine the effect of yarn count(combination of Ne 30's, 40's, 50's(CM)) and stitch density(CPI of 34, 37, 40) of interlock knitted fabric on the torapability and functional value which were derived from the basic mechanical properties for the purpose of provide the basic data for constructing high functional knitted fabrics were produced with good appearance and wear sensation. The experimental results were statistically analyzed to investigate the elects of drape coefficient, functional values and mechanical properties by knitting conditions.
