  • Textile composites란 직물, 편성물, 브레이드 등을 사용한 섬유강화 복합재료의 총칭으로서 텍스타일이 지닌 뛰어난 기능을 매트릭스에 부가함에 따라 단일재료로는 얻지 못하는 뛰어난 공업재료를 만들 수 있다. 편성물은 직물이나 브레이드에 비해서, 변형특성도 매우 우수하고 고생산성이다. 복합재료에서 강화재로 편성물을 사용하는 경우, 섬유소재, 편조직, 편환 밀도 등을 고려하는 것에 의하여 편성물 강화 복합재료의 역학적 특성이 달라진다. (중략)

  • 편성물은 느슨한 루프에 의해 구성되어 있으므로, 직물에 비해 신축성이 커서, 체형에 밀착되며, 인체의 움직임에 따라 쉽게 움직인다. 그러나 높은 신축성 때문에 편성물을 재단할 때 결을 벗어나면서 자르기 쉽다. 보통 직물의 신도는 10-20%이나 위편성물은 100-200%, 경편성물은 40-100%의 신도를 나타낸다. 편성물의 높은 신축성은 신축성과 함께 유연성을 주지만, 착용과 세탁 후의 외관을 해치게 되는 결과를 낳을 수도 있다. (중략)

  • 편성물은 직물에 비하여 신축성, 함기량, 유연성, 방추성 등이 우수하여 스포츠웨어와 캐주얼웨어에 수요가 크게 증가하고 있어서, 편성포의 외관(감각적 성능)과 쾌적성능이 매우 중요한 요소로 대두되었다. 특히 위편의 경우에는 생산공정이 간단하면서도 다양한 조직으로 편성할 수 있어 다양한 용도로 활용이 넓어지고 있는 추세이다. 그러나 이러한 편성포의 물성들은 편성구조나 편성조직에 따라 변화한다고 알려져 있으나, 직물에 비교하여 편성물의 물성에 대한 구체적이고도 체계적인 연구는 아직까지 미흡한 실정이다. (중략)

  • 편성물은 신축성이 좋으므로 의류용 소재로써 다양하게 사용되어지고 있다. 편성물의 장점으로는 직물과는 달리 루프 형태로 얽힌 편환으로 구성되어 있기 때문에 제편 과정에서 필요한 형태로의 성형이 용이해서 제품의 다양화를 기대할 수 있다. 뿐만 아니라 신축성과 유연성, 다공성, 구김안정성 등이 우수하여 인체의 여러 가지 활동에 따른 구속감이 적으며 인체의 굴곡을 아름답게 나타내어 주는 등의 장점이 있어 의복 소재로써 차지하는 비중이 높다. (중략)

  • The purpose of this study were to analyze the effect of weft knit structural characteristics on the subjective texture and sensibility. For this, the material was knitted into 8 kinds of weft plain knit fabrics with four kinds of fiber components such as wool, acryl, rayon, and nylon, 3 steps of densities and 3 steps of twist numbers to ply two yarns. The data were analyzed by factor analysis, ANOVA and multidimensional scaling. From factor analysis, subjective textures were categorized as 'bulk/resilience', 'surface/density' and 'soft/drape', and subjective sensibilities were categorized as 'natural/comfortable', 'feminine/elegance' and 'stable/neat' Among the knit structural characteristics, the component of fibers and the density of fabrics were the important factors to give variations in texture and sensibility : In comparison with wool knit of medium density, the knit fabrics of other components and different densities each showed a unique texture and sensibility. But twist number to ply two yams had a few influence on subjective properties. As a result of MDS analysis, the texture and sensibility of plain weft knit fabrics was classified as 'thin-full', 'hard-soft', 'young-old' and 'warm-cool'.

  • This research investigated the mechanical properties of the 4 different types of $3{\times}3$ cable stitches on weft knitted fabrics. The 4 kinds of cable-stitch fabrics were knitted under the same knitting conditions, then the mechanical properties, such as tensile strength, elongation, stiffness, etc. were measured according to the Korean Industrial Standards (KS K 0642). The knitting time for the sample produced by the knitting process 1 was the shortest among the 4 different types of samples. It means that the knitting process 1 would have benefits of higher productivity if there is no yarn breakage during the knitting of the cable stitches. In the test for tensile strength, the samples produced by knitting processes 3 and 4 have tensile values of approximately 8~11% higher than the sample produced by knitting process 1. The test for elongation also shows that the samples produced by knitting processes 3 and 4 have up to 18% higher elongation values than the sample produced by knitting process 1. On the other hand, the stiffness test showed no significant difference between the 4 samples. This study is expected to increase the competitiveness of the local knitting industry as a result of providing basic data on the mechanical properties of special knitted stitches, such as cable stitches.

  • The purpose of this study is to investigate change of mechanical and physical properties, shape behavior and hand value in weft knit when rib stitch and milan stitch are combined. The knit stitches used in this study are plain stitch, half milan rib stitch, milan rib stitch, $2{\times}1$ rib stitch, $2{\times}1$ half milan rib stitch and $2{\times}1$ milan rib stitch. We analyzed physical and mechanical properties(tensile, bending, shear, compression, surface properties, thickness and weight) of the knit stitches and calculated their primary hand value and total hand value through translational formulas using the KES(Kawabata Evaluation System). The results are as follows; In evaluation of mechanical properties and hand values of knit stitches, plain stitch had the highest flexibility and the lowest T.H.V. as women's winter knit wear. Since $2{\times}1$ rib stitch had too high elongation in one direction, although it had the highest T.H.V, it needs to be careful when plain stitch and $2{\times}1$ rib stitch are applied for women's winter knit wear. Since Milan rib stitch and $2{\times}1$ milan rib stitch had high T.H.V. similarly, it is considered that they are suitable for women's winter knit wear. Specially, when Milan stitch is combined with $2{\times}1$ rib stitch, its shape stability and fullness are contained and flexibility is added on it. Therefore, $2{\times}1$ milan rib stitch can be also applied for women's winter knit wear.

  • The purpose of this study is to analyze the structural properties of 100% wool fabrics knitted with various stitch types and to evaluate dimensional stability from shrinkage in wet cleaning and drying. Materials were weft-knitted from twenty-four different stitches with 7 gauge using a computerized flatbed knitting machine. Weight, thickness, density, and length were measured. A domestic washing machine and a tumble dryer were used for the shrinkage test. The results are as follows: Knitted fabrics were divided into 3 groups based on weight per unit area. Porous knits show light weight whilst milano, pintuck, rib stitches belong to the heaviest group. A positive correlation between weight and thickness was found and the same result was obtained for wale density and weight. Dimensional shrinkage of knitted fabrics was increased during repetitive wet cleaning and drying regardless of knit stitches. Especially, fabrics knitted with float, tuck, cable, and links & links stitches samples were contracted more than 15% in the first treatment whereas 2x1 rib stitch showed 1% shrinkage rate. Fisherman and milano stitches contracted in both course and wale direction with similar shrinkage rates. However, porous knits with float and tuck stitches shrank in course direction by 20% as well as cable samples contracted from 5% to 20% after repeated washing and drying. On the other hand, 30% and 15% contraction of wale direction occurred in orderly float and links & links stitches, respectively. Machine dried knits have a higher shrinkage rate than air-dried knits, but the drying method did not affect to the direction of contraction. In conclusion, variations of knit, tuck, and float stitches affect knit construction and dimensional stability from shrinkage in wet cleaning and drying of wool knitted fabrics.

  • The purpose of this study is to develop the relationship model among subjective texture and preference of weft knit according to fiber contents of wool/rayon and loop length by integrating previous research work. SPSS and SEM method using AMOS program were used to analyze data which used to correlation matrix to be standardized. The texture of weft knit were classified into 4 categories: irregularity, flexibility, bulkiness, extensibility. The fiber contents of wool/rayon had effect positively on irregularity, bulkiness and extensibility and that had little effect on preference. The loop length had effect positively on irregularity, flexibility and extensibility and that had effect negatively on preference. This measurement model will be input for testing causal research model that can explain how fiber contents of wool/rayon and loop length of weft knit influence on subjective texture.
