研究PTT棉交织物的弹性.选取纬纱均为PTT无捻低弹长丝的11种交织物,测试了其弹性伸长率和弹性恢复率,并采用多元线性回归方法分析了PTT棉交织物结构参数与弹性伸长率和弹性恢复率的关系.研究结果表明:织物的组织浮长对织物弹性伸长率的影响最大,其次为经向上机紧度;织物的弹性恢复率主要受纬纱细度和织物在弹力方向伸长的影响. 相似文献

为了解PTT/PET三维卷曲复合丝及其不同织物参数对织物拉伸性能的影响,通过改变PTT/PET复合丝比例、捻度、织物组织和纬密4个参数织造了33种织物,测试并分析了这些织物的拉伸性能指标。研究发现:PTT/PET双组分长丝织物拉伸断裂强力较低,而断裂伸长较高,低负荷条件下织物具有高伸长特性;在相同的条件下,随着纬纱PTT/PET含量提高,断裂强力呈下降趋势而断裂伸长相应提高,纬密主要影响织物拉伸断裂强力,对断裂伸长的影响不大,PTT/PET复合丝的捻度对低负荷条件下织物拉伸性能影响明显,因织物组织不同其拉伸性能也存在一定差异。 相似文献

Twelve stretchable fabrics are woven in two sets with one set in 50s and 60s 100% cotton in warp and 40s, 50s, and 60s cotton core spun lycra yarn in weft and another set with 2/75 and 2/120?Nm silk in warp with 40s, 50s, and 60s cotton core spun lycra yarn in weft. Hundred percent cotton sari blouse materials commercially available in the market are also included for a comparative study of pressure distribution between cotton core spun lycra fabrics and cotton blouse materials. The influence of fabric specification on total hand value (THV), stretch properties, and pressure comfort is analyzed. The effects of body shape and fabric mechanical properties on garment pressure are also analyzed. The results indicated that the finer counts of cotton core spun lycra woven with cotton and silk to elasticize fabrics provided improved hand feel, stretch, and pressure comfort values. The average pressure value of the samples at the major pressure points with the cotton/cotton core spun lycra samples and silk/cotton core spun lycra samples is lower than 100% cotton samples’ fabric physical properties, stretch properties, mechanical properties, and THV significantly influenced the pressure distribution and comfort of garments. 相似文献

文章采用全聚纺纺纱方式生产了JC/PET、JC/PTT、JC/SPH、JC/T400四种包芯纱和一种纯棉纱,利用这五种纱线织造了规格相同的五种机织物。分别利用客观与主观评价法,评价织物的抗皱性及平整度等级,同时测试了织物的拉伸弹性回复率,以研究芯丝种类对织物抗皱性及抗变形性的影响。结果表明:芯丝的加入可以改善纯棉织物的平整度;长丝的初始模量、弹性影响织物的抗皱等级,SPH的初始模量最高、T400的弹性回复性最好,因此JC/SPH和JC/T400包芯纱织物抗皱等级最高,可以达到3. 5级;且这两种长丝的表面均有沟槽,截面为异形,起到毛细管作用,其织物具有较好的吸湿排汗作用,是开发高保形免烫衬衫面料的理想选择。 相似文献

本文选择了cooldry吸湿速干涤纶、Thermolite保暖涤纶和Tencel再生纤维及氨纶/锦纶弹力包芯纱分别为面纱和地纱,采用平纹添纱组织和N6上机密度设计与织造了4组16种交织物。对织物的纵横向密度、平方米重及厚度,拉伸伸长率及弹性回复率进行了测试与分析,并采用一元方差分析了交织对无缝内衣面料结构规格与伸缩性影响的显著性。结果表明,交织对织物纵横向密度、平方米重及厚度,拉伸伸长率影响均十分显著,对织物弹性回复率影响不显著;织物密度、单米重、厚度及拉伸率较大的交织方式为:面纱、地纱均为弹力包芯纱与非弹力纱间隔1根排列,或织物面纱为非弹力纱,地纱为弹力包芯纱。其研究结果对无缝内衣的设计与开发具有一定的参考价值。 相似文献

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. 相似文献

Elastic structures are preferred for improving the elasticity and recovery properties of denim fabrics. With the intention of improving comfort during body movements in denim jeans, 10–35% elasticity is required. In this study, the effect of the composition of double-core (dual-core) and core-spun weft yarns and weft density on the mechanical properties of denim fabrics was investigated. For this purpose, different core materials were used in the production of elastic yarns. The sheath material was cotton for all yarn types. Yarn samples were spun with the same yarn count and twist coefficient. 100% cotton Ne 8/1 Ring slub warp yarns were used as warp yarn while double-core and core-spun yarns were used as weft yarns in weaving. The weaving process was performed with three different weft density values (16, 22, and 28 weft /cm) and the other production parameters were kept constant. Twill 3/1 woven fabrics were treated according to standard denim finishing procedures. After domestic washing processes, mechanical properties of the samples were tested and statistically evaluated. 相似文献
