纯棉织物免烫整理后,拉伸、撕破强力下降,严重影响了织物的耐用性.通过研究免烫整理前后织物的拉伸和撕破强力、纱线的强力和伸长率、交织阻力、形态结构,分析影响撕破强力的因素.研究表明,纱线结构、强力以及伸长率对撕破强力有显著影响.强力和伸长率高的纱线织成的织物被撕破时受力三角区大,共同受力的纱线根数多,撕破强力高;组织结构、经纬纱密度影响纱线间的交织点及滑移情况.交织点少,纱线间滑移容易的织物的撕破强力高.  相似文献

外部压力对液体在织物间传导有很大的影响,较高的压力能触发液体在织物间传导的发生.至于外部压力对织物间液体传导速度的影响,则存在一个压力最佳值,在最佳压力值下,织物间液体的传导最快.湿层织物初始含水量高则明显地增加了织物间液体的传导量.由于单面毛绒织物的两面具有不同的毛细管尺寸,当干层织物的光面与湿层织物的光面和毛面分别接触时,液体在织物间发生转移,传导量前者大于后者;当干层织物的毛面与湿层织物的光面和毛面分别接触时.织物间没有液体转移现象发生.  相似文献

以涤纶基导电长丝为芯纱、锦纶低弹丝为固结纱、羊绒粗纱经牵伸后为饰纱,开发了4种抗静电羊绒花式纱线(花式平线、波形线各2种),并分别制成纬平织物.对织物的抗静电性能进行测试,对比试验结果表明,抗静电羊绒花式纱线织物的电荷面密度仅为同线密度纯羊绒织物的1/8.同时分析了花式纱线的结构和包缠捻度的大小对织物抗静电性能的影响,研究发现:花式平线的导电效果优于波形线;随着捻度增加,由抗静电羊绒花式纱线制成的织物电荷面密度有减小的迹象.  相似文献

To find out the reason of resulting in the crease recovery of a fabric and provide theoretical guidance for designing a new material with good creasing-recovery property,the relationship between the creasing-recovery force and the crease-recovery angle of a woven fabric was investigated by self-setup experimental device.The results show that the crease-recovery angle of a woven fabric is correlated with the creasing-recovery force of the fabric in a linear relation.Furthermore,it is found that the internal stress is the principal force of affecting the creasing-recovery property of a woven fabric.In addition,the relationship between the tensile property of a woven fabric and the creasing-recovery property of the fabric has also been investigated,showing that the lower relaxation velocity of tensile stress of a fabric is,the better creasing-recovery property of the fabric has.  相似文献

IntroductionProtective materials are classified into impermeable,permeable, permeable absorptive and engineered permeablematerials[1,2,3,4].Impermeable materials prevent permeation of aerosols,liquids, and vapors. This applies to exterior contaminated airas well as to moisture and vaporproduced bythe user, creatinguncomfortable environments when used for personal protectiveitems. Butyl rubber and polyethylene ( PE) film are typicalexamples. Butyl rubber and PE protective …  相似文献

Silicone coatings have been used in this study. The method adopted was the liquid drop analysis on the coated fabrics. The contact angle between a liquid drop and the fabric surface was measured with two liquids continuously and recorded by a computer. The surface energy was calculated by means of Owens method. Kinetic measurement was adopted. The contact angle of liquids on the fabric coated silicone decreased with time was found. A compound solution DX has been found, so that the contact angle of the liquids on the fabric washed with DX becomes constant, and the surface energy of the fabric can be reduced to below 15 mJ/m2.  相似文献

We investigated the influences of liquid water transfer property of cotton fabric on human physiological responses, such as ear canal temperature, heart rate, blood pressure, stress hormone, during exercise and recovery. Long sleeves cotton knitted sportswear treated to have special liquid water transfer property were prepared; (1) Hydrophilic; ( 2 ) Hydrophobic; and ( 3 ) Moisture Management (MM). Wearing these garments, human subjects ran on treadmill according "to a pre-designed experimental protocol. It was found that during exercise hydrophilic cotton caused significantly higher mean skin temperature than MM and hydrophobic cotton fabrics, while during recovery, hydrophilic and MM cotton fabrics caused significantly higher mean skin temperature than hydrophobic cotton fabric. Hydrophilic cotton fabric caused significantly lower heart rate than MM cotton fabric, lower systolic blood pressure than MM and hydrophobic cotton fabrics. Hydrophobic cotton fabric caused significantly higher urinary catecholamine volume than hydrophilic and MM cotton fabric, indicating stronger physical stress. Hydrophilic cotton fabric caused significantly stronger thermal and humidity sensations than MM and hydrophobic cotton fabrics at the end of first and second exercise sessions. Hydrophilic cotton fabric caused significantly stronger discomfort sensation than hydrophobic cotton fabric at the end of first session of exercise. In the end of wear trial, MM cotton fabric caused significantly higher tiredness sensation than hydrophilic and hydrophobic cotton fabrics.  相似文献

在精纺毛织物缝合工艺体系中,缝边的不同纱向角度对缝合的最大缝缩率的影响是结构和工艺立体配伍的基础.为构建最大缝缩率的理论方程,从力学平衡角度探讨面料力学性能对缝缩率的影响,分析不同纱向角度的面料之间缝合最大缝缩率的关系.研究表明,在纱向角度为0°~45°时,面料的最大缝缩率随纱向角度的增大而增大;在纱向角度为45°~90°时,面料的最大缝缩率随纱向角度的增大而减小.试验验证结果表明,本文提出的轻薄精纺毛织物不同纱向角度面料最大缝缩率理论模型具有一定的实用操作性.  相似文献
