Muhammad Umar Nazir Khubab Shaker Yasir Nawab Muhammad Zohaib Fazal Muhammad Imran Khan 《纺织学会志》2017,108(8):1319-1326
The paper focuses on the development of a bilayer-woven fabric and investigating the effect of weave design and material type on its comfort properties. Face layer was plain woven with cotton yarn, while two different weave designs (2/2 and 3/1 twill) and four different materials (cotton, polyester, micropolyester and nylon) were used for the back layer. The comfort properties of fabric, including air permeability (AP), thermal resistance, water vapour resistance and overall moisture management capacity, were determined. It was found that both the layers of fabric as a whole contribute to the comfort properties of bilayer fabric. The highest AP was exhibited by fabrics having both layers of cotton, while 3/1 twill samples have a lower value of thermal resistance as compared to the 2/2 twill samples. The results further showed that micro polyester woven in 3/1 twill weave exhibits better comfort properties. 相似文献

为使织物同时获得较好的防紫外线和防电磁辐射的功能,且保持功能的持久性,设计了由织物基层、防护层和纳米二氧化钛涂层3 部分组成的防护织物。防护层采用超细镀银涤纶丝作为原料,按照加强斜纹组织结构设计,与织物基层以双层组织原理按照自体接结的方式进行连接,在防护层外侧用纳米二氧化钛防紫外线涂料进行涂层整理,并测试织物的紫外线防护性能和防电磁辐射性能。根据正交试验结果,利用灰色聚类分析确定最优工艺参数。结果表明:防护织物的紫外线防护系数为60.1,平均屏蔽效能为99.992 0%;最大屏蔽效能为99.998 9%,所对应频率为120 MHz;最小屏蔽效能为99.958 6%,所对应频率为205 MHz。 相似文献

探讨织物组织结构对衬衫面料撕破强力的影响.以纯棉、棉涤混纺、棉涤混纺加少量天丝为原料,织造不同组织结构的织物:平纹、斜纹及纵条纹组织,所有试样均采用同样的液氨免烫后整理工艺.采用冲击摆锤法测定织物的撕破强力,并且从紧度比对撕破强力、织物组织对纯棉试样撕破强力,以及原料对撕破强力的影响三个方面进行分析.结果表明,随着织物的经纬向紧度比增大,织物的纬向撕破强力呈递增趋势;对于常见规格的纯棉织物,平纹组织的经、纬向撕破强力均小于其他组织,尤其是纬向撕破强力较容易出现不合格情况,斜纹组织织物的撕破强力较高,纵条组织织物的撕破强力因组成条纹的各基本组织的配置不同而不同,其撕破强力一般介于平纹和斜纹组织织物之间;在棉涤混纺加入少量天丝时,平纹组织织物的撕破强力会明显提高.产品设计中合理设计织物结构,使经纬向紧度比增大,可以提高纬向的撕破强力. 相似文献

根据常见的衬衫面料组织结构,使用JC9.7 tex纱线设计了6种不同组织结构的面料,研究不同组织结构对织物保形性的影响。对面料的保形性(尺寸稳定性、抗折皱性、外观平整度、抗起毛起球性、顶破性、悬垂性)及舒适性(透气、透湿性)进行了测试。结果表明:组织结构对织物的折皱回复角、外观平整度等级、顶破强力、透湿量与透气率有直接影响;织物紧度太大、太小都不利于织物的折皱回复,相同紧度下斜纹组织的抗皱性比平纹好;6种组织结构中2/2斜纹组织抗折皱性最好,2/2方平组织的顶破强力、抗起毛起球等级最高,2/2破斜纹透气、透湿性最好,2/2斜纹组织具有良好的保形性。 相似文献

Fabric structure has a significant effect on the thermal protective performance of fabrics. Before studying the thermal performance of textiles by numerical methods, it is essential to create geometric models of textile structures. Common fabrics, such as plain weave, 2/1 twill, 3/3 twill, 5/3 satin, and double layer fabric, were modeled using TexGen software. To obtain the input data for geometry simulation of fabrics, geometric measurements were studied. Methods of modeling fabric geometries according to their yarn path function and cross-sectional shapes were introduced. The appearances of the geometric models were very close to the structures of the real fabrics when compared to their light microscopic images. The fabric models were well used to simulate the heat transfer properties of glass fiber fabrics. 相似文献

In this study, six different woven samples were produced on air jet loom with two different weave designs (i.e. 3/1 twill and 1/1 plain), three different picking sequences (i.e. single pick insertion (SPI), double pick insertion (DPI) and three pick insertion (3PI)). All the woven samples were singed, desized, bleached and finished together at industrial scale, as a single lot. The effect of these factors on the wetting, wicking and air permeability (AP) of the fabric samples was analysed. It was revealed that the fabric weave design and picking sequence has statistically significant effect on fabric wetting time, water spreading speed and AP of the fabric. It was found that fabrics woven in twill weave design and with simultaneous 3PI give significantly better AP, shorter wetting time and better water spreading rate as compared to plain woven fabrics and those with double or SPI. It could be concluded that the thermophysiological comfort of woven fabrics may be significantly improved simply by selecting a suitable weave design and picking sequence. 相似文献

为研究组织结构与磨损对织物屏蔽性能的影响,以及不锈钢长丝对织物折皱回复性的影响,使用自制的棉/不锈钢长丝包芯纱织制了3种不同组织的机织物,测试了织物在0.3~1 500 MHz频段上的电磁屏蔽性能,并使用平磨仪对各织物分别摩擦60、120、180、240 及300次后,测试了织物磨损后的电磁屏蔽性能;同时,采用视频序列法测试了织物的动态折皱回复角。结果表明:织物组织结构对电磁屏蔽性能有一定影响,平纹组织结构紧密,屏蔽效果好;经过若干次磨损后,织物的电磁屏蔽性能先小幅升高后逐渐降低;相同磨损条件下,试样耐磨性越好,屏蔽效能的降低幅度越小;由于不锈钢长丝的加入使织物的折皱回复性降低,可以采用浮长更长的组织改善织物起皱现象。 相似文献

The yarn structure and fabric interlacing pattern are determining parameters for fabric properties. The current study focusses on the multi-response optimization of certain fabric properties like shrinkage, areal density, thickness, flexural rigidity, and bending modulus using principal component analysis for optimum properties. Yarn twist (four different levels), fabric weave design (plain and twill), and yarn type (carded and combed) were the variables of the study. The Taguchi approach of the orthogonal array was sued for designing the experiments, and eight different samples were produced. The yarn twist and fabric weave design were found to have significant effect on these properties of the fabric. Furthermore, using analysis of the variance method, contribution% of parameters to these properties was determined. 相似文献

This study presents the thermal comfort properties of woven fabrics made of Kermel, cotton/nylon and cotton/nylon /Kermel-blended yarns. Our aim in this study is to combine the high comfort properties of cotton/nylon fibres with high thermal protective properties of Kermel fibre in different woven fabrics. Thus, Kermel (100%), cotton/nylon (50:50) and four blends of the 50% cotton fibres with nylon and Kermel (40:10, 30:20, 20:30 and 10:40) were spun on a ring-spinning frame and twisted into two-folded yarns with the same yarn count of 30/2(Ne) and twist level of 560 TPM. Using the produced yarns, woven fabrics with identical characteristic and structure were also produced. Then, the thermal comfort and physical properties of fabrics were studied in terms of fabric porosity, thermal resistance, thermal conductivity, water vapour resistance and air permeability. The results show that the porosity, air permeability and thermal resistance increase with Kermel fibre blend ratio. Conversely, the water vapour resistance decreases with increase of Kermel fibre blend ratio up to 40%, while 100% Kermel-woven fabric exhibits a higher water vapour resistance value. Nevertheless, the thermal conductivity of cotton/nylon-blended Kermel woven fabric is unchanged with increase of Kermel fibre blend ratio up to 40%, whereas at 100% Kermel fibre blend ratio, the lowest thermal conductivity is obtained. The obtained results implied that woven fabric produced from cotton/nylon (50/10) blended with 40% Kermel fibre resulted in proper thermal comfort properties. 相似文献

This study examined a simple and rapid hydrothermal approach for zinc oxide (ZnO) functional fabrics. ZnO-coated cotton fabrics were achieved by this hydrothermal. The surface morphology, crystalline structure, surface chemistry of the uncoated and coated cotton fabrics were investigated by scanning electron microscope, X-ray diffractometer, Energy dispersive X-ray spectroscopy and Fourier transform Infra red spectroscopy, respectively. Ultraviolet properties and washing fastness of treated cotton fabric were also measured. The results indicated that the sizes of 100–500 nm spherical ZnO nanoparticles were successfully deposited on cotton fiber surface. These spherical ZnO nanoparticles were uncompleted crystal structure. Chemical bond between ZnO nanoparticles and cotton fiber was also observed. ZnO-coated cotton fabrics exhibited better ultraviolet-resistant properties than that of uncoated cotton fabrics. Washing resulted in a dramatic decrease in the UPF of ZnO-coated fabrics, but the UPF of coated fabrics was still up to 30.1 after 90 min of washing. All results suggest that this method had good potential in preparing ZnO functional textiles. 相似文献
