为探究经编结构和原料配置对织物单向导湿性能的影响,对织物各梳栉的调整、原料的配置和织物结构进行选择。设计8个样品,通过对其水分管理性能研究对比后发现,内层纱线和外层纱线线密度差异越大,织物的单向导湿性能就越好。在原料配置方面,内侧选用5.6 tex(14 f)涤纶低弹丝,外侧选用8.3 tex(288 f)的涤纶低弹丝具有最佳的水分管理性能;而内层选用5.6 tex(14 f)的涤纶低弹丝,外层选用9.7 tex的棉纱具有较高的润湿时间和吸收率,但其内外层润湿时间差、最大润湿半径和扩散速度较低,会影响面料对人体的穿着舒适度。在结构方面,外层采用经绒组织,内层采用编链,其整体水分管理性能要优于内层采用经缎组织,且织物内层纱线垫纱成圈织针数越少有利于增强单向导湿性能。 相似文献

采用不同细度的环锭纺棉纱线,通过切片观察和分析计算,确定纱线断面的孔隙率及其分布。研究表明:线密度不同的环锭纱线,其平均孔隙率一般都在10%~30%之间,但不同线密度纱线的平均孔隙率有差异,纱线越粗,平均孔隙率越大;在环锭纱线截面上中间层的孔隙率最小,呈现出紧密结构,纱线外层的孔隙率最大,呈现出松弛结构,内层孔隙率较小。 相似文献

Dyform 28 HML钢丝绳外层16根压实股、内层3根压实股、次外层6根小直径压实股与3根相对较大直径压实股,2次合绳,对外层绳压实。研究发现其特点:(1)抗旋转性能优异;(2)破断拉力高、结构稳定性好,与匹配滑轮(卷筒)接触面积大;(3)内外层绳反向捻制导致对外层绳压实量不大,破断拉力与35(W)×K7类钢丝绳相当;(4)抗冲击性能与27×K7类钢丝绳相似;(5)密实结构外层股数为内层股数的3倍,且外层同层股直径不同,相对内层股数相同的瓦林吞密实钢丝绳组绳股直径均匀;(6)内层绳股股结构不同可提高内层绳股疲劳性能并适度改善钢丝绳的柔软性。 相似文献

棉及其混纺纱线织物活性染料染色后常见清洗方法是使用皂洗剂去除浮色。采用还原剂SRC进行清洗试验,以破坏浮色发色基的理论为依据,首次发现还原剂SRC可用于活性染料染色后的清洗中,其最佳使用量为1.0~1.5 g/L,清洗浴pH值为4.0~4.3,温度控制55~60℃,时间为5~10 min。还原剂SRC清洗对棉及其混纺纱线的色光没有影响,尤其对于染深色和特深色纱线或织物表面浮色的去除非常有效,保证了色牢度。与活性染料的常规皂洗剂工艺相比,还原清洗工艺是一种具有节能、节水、省时、省力、环保、提高效率的新工艺。 相似文献

The colour values of fabric samples that are knitted from vortex-spun (VS), open-end rotor-spun and ring-spun yarns were evaluated after abrasion. We measured the changes of colour properties of each sample, considering spinning system, dyeing concentration and abrasion cycle, which have effects on colour values. The colour values of dyed fabrics knitted from ring spun yarns showed less change after abrasion than that of dyed fabrics knitted from open-end rotor-spun and VS yarns, when the spinning systems were compared. The colour values of dyed fabrics knitted from VS yarns showed more changes after abrasion because of the smooth surface of VS yarns. 相似文献

Because of their importance in some apparel, hand-knitted, and upholstery fabrics, an attempt is made to classify fancy yarns and to study the effect of parameters such as linear densities, bulk coefficients, and colour content in soufflé, ombré, and woollen yarns. The results may help to form a basis for improving repeatability and for engineering new yarns. 相似文献

Multilayer woven fabrics are conventionally represented with the usual weave notation of black and white squares. This notation is based on the top view of the woven fabric. Side view of multilayer woven fabrics contains more important information, namely the routes of warp yarns between layers of weft yarns. In this study, possibilities of woven structures with any numbers of layers and corresponding warp and weft yarns are described. Formulas are derived to describe horizontal, vertical, and diagonal symmetries which lead to identify the fully independent structures. The results serve as the theoretical ground to determine all the possible mechanical properties by using woven reinforcements. 相似文献

Double-face knitted fabrics with hydrophobic inner and hydrophilic outer layers are characterised by their advantageous thermo-physiological comfort property that facilitates the transport of sweat from skin to outer fabric layer where it can be evaporated easily. In this study, for the production of double-face knitted fabrics, cotton yarn as hydrophilic yarn type and five different polyester filament yarns consisting of standard polyester, hollow polyester, micro polyester, textured polyester and textured micro polyester as hydrophobic yarn type were used. In order to determine the thermo-physiological comfort properties of the fabrics, air permeability, water vapour permeability, thermal conductivity, thermal resistance and overall moisture management capacity were measured. The results were comparatively analysed using statistical methods. The experimental results demonstrated that the polyester-type yarns and the combinations of them with the cotton yarn in fabric layers affected the thermo-physiological comfort properties significantly. The fabrics with polyester-type inner face and cotton outer face showed the best moisture transmission properties. 相似文献
