Investigation on moisture management properties of knitted fabrics produced from vortex-spun yarns

Abstract

The aim of this study was to investigate the liquid moisture management performance of knitted fabrics produced from vortex-spun yarns using different kinds of fibers and ratios. For this purpose, the vortex-spun yarns with 19.7 tex were obtained in different blend ratios in Murata Vortex Spinner by using different fibers. Then, these yarns were knitted in a circular knitting machine at two different stitch lengths and dyed considering fiber types. Moisture management properties of the produced fabrics were tested. The results revealed that moisture management properties of vortex knitted fabrics were much affected by fiber types in comparison with fabric tightness. Modal and nylon fibers have shown very positive results in terms of moisture management performance. The vortex-spun yarns having a low diameter, high shape values that are more rounded, and high density improved moisture management performance of the fabrics whereas the hairy yarns and higher fabric thickness reduced it.

Physical properties of ring,compact, and air vortex yarns made of PTT/wool/modal and wearing comfort of their knitted fabrics for high emotional garments

This study examined the physical properties of PTT/wool/modal yarns according to the yarn structure and the wearing comfort of their knitted fabrics for high emotional garments. For this purpose, the air-vortex, compact, and ring yarns and their knitted fabrics were prepared to analyze the wear comfort according to the yarn structure and the possibility of applications of the PTT/wool/modal blend fibers to air-vortex yarn. The wicking and drying rates of the air-vortex yarn knitted fabrics were superior to those of the ring and compact yarns fabrics, and the heat-keeping capability of the air-vortex yarn knitted fabric was higher than those of the ring and compact yarns fabrics due to the low thermal conductivity and maximum heat flow rate. In addition, the pilling of the air-vortex yarn knitted fabric was less than those of the ring and compact ones due to the air-vortex yarn structure with parallel fibers in the core part and the periodical and fasciated twists on the sheath part of the yarns. The tactile hand of the air-vortex yarn knitted fabric was harsher than those of the ring and compact yarns knitted fabrics because of the low extensibility and compressibility, and the high bending and shear rigidities.

Study on the bagging behavior of knitted fabrics by shape memory polyurethane fiber

The shape memory polyurethane (SMPU) fabrics were knitted with different SMPU fiber contents for the investigation of its bagging behaviour in this paper. The bagging deformation and recovery of these SMPU-knitted fabrics were determined at different temperatures to evaluate its temperature sensitivity. Our experimental results show that the bagging behavior of the SMPU-knitted fabrics is highly correlated with the amount of SMPU fibers knitted inside the SMPU fabrics. The switching temperature of the SMPU-knitted fabrics is found to be above the phase transfer temperature of SMPU. A comparison between Lycra and SMPU-knitted fabrics is also conducted to validate the shape memory bagging behavior of SMPU-knitted fabrics.

组织结构对针织物电磁屏蔽效能的影响

设计了几种代表性织物组织结构的不锈钢纤维混纺针织物,研究了织物组织结构对针织物电磁屏蔽效能的影响。织物组织结构选择充满系数较高的双罗纹组织、打鸡双面组织、添纱衬垫组织、衬纬组织和绕经组织,以降低织物厚度、密度、孔隙等因素对织物电磁屏蔽效能的影响。对所有织物进行了电磁屏蔽效能测试,结果显示:双罗纹织物、双面织物、添纱衬垫织物、衬纬织物的电磁屏蔽效能都很不理想,且远远低于含不锈钢纤维机织平纹布,但是绕经织物的电磁屏蔽效能要比其他组织的针织物的屏蔽效能高得多,基本能达到国标上对屏蔽服的屏蔽效能要求。绕经织物与其他几种针织物最大的不同就是在纵向多了一些连续的含不锈钢纤维的混纺纱。说明针织物组织结构是影响电磁屏蔽效能的关键因素,可通过在织物纵横向形成纵横交错的导通的金属网栅的方式来改善不锈钢纤维混纺针织物的屏蔽效能。
