探讨影响织物撕破强力的因素。分析了织物撕破时的受力情况,采用梯形法测试了不同纬密、纬纱强力、纬纱号数、组织条件下织物的撕破强力。试验表明:织物纬向撕破强力随纬密的增大而增大,当纬密达到一定数值时,织物纬向撕破强力开始下降;织物纬向撕破强力随纬纱强力的增大而增大;同原料同紧度的织物纬向撕破强力随纬纱号数的增大而增大;其他条件一定的情况下,织物纬向撕破强力随经浮线增长而增大。指出:通过分析织物纬向撕破强力的影响因素,有助于高撕破强力织物的设计。 相似文献

研究了不同机械搅动条件对酸性纤维素酶吸附和水解性能的影响,结果发现:在高搅动条件下,酸性纤维素酶对纤维素织物的吸附速度更快;由酶水解所释放出的还原糖量也相应增加,引起的织物失重率也更大.测试处理后织物的强力表明,酸性纤维素酶对织物的强力损伤在高搅动条件下更明显. 相似文献

为探究经编和机织涂层膜结构复合材料的光氧老化行为,以涤纶经编和机织聚氯乙烯(PVC)涂层膜结构复合材料为对象,选取6种织物试样,研究其在紫外光辐射下的老化现象,同时与涤纶纱线力学性能的老化效应进行对比;同时研究了老化实验过程中复合材料的光氧老化行为及力学性能变化,并分析了其微观损伤机制。结果表明:涂层膜对基布纱线起到了很好的保护作用;经编织物膜结构材料老化后的初始模量均高于机织物膜结构材料,断裂强力保持率则反之;在辐射能为82.08×103 kJ/m2时,织物的横密和纵密均为24根/(5 cm)的单面经编膜结构复合材料断裂强力保持率仅为62.4%,且其涂层对基布的保护作用已失效,涂层膜表面严重粉化和黏结;另外5种双面膜结构试样断裂强力保持率均在85%以上,在此辐射能范围内涂层面变粗糙,但仅出现少量沟槽,表现出良好的抗光氧老化性能。 相似文献

In this study, water-repellent, oil-repellent and flame-retardant cotton fabrics were developed by solgel technique. With this aim, nanosols were prepared using tetraethylorthosilicate and hexadecyltrimethoxysilane as precursors, guanidine dihydrogen phosphate as flame-retardant agent and Guard AFB as conventional water–oil-repellent agent, solvents and chelating agents. Then, to AC105, VA7110, PU1110 and FC9005 as polymeric additives, with/without FX8000 or urea and formaldehyde as cross-linking agents, were added some nanosols to improve washing fastness of the fabric samples. Cotton fabrics were treated with nanosols without polymeric additives by pad–dry–cure process, while they were coated with nanosols containing polymeric additives by knife-over-roll coating. Water–oil-repellent properties, flame-retardant properties, washing fastness, contact angle, whiteness, tear strength and add-on values of the coated fabric samples were determined. It was found that the cotton fabrics with good water–oil-repellence and flame-retardant properties with relatively durable properties could be produced using nanosols containing guanidine dihydrogen phosphate and urea, together with tetraethylorthosilicate and hexadecyltrimethoxysilane as precursors, and lower concentrations of Guard AFB as commercial water–oil-repellent agent. However, the fabric samples were still not sufficiently durable when washed. It was deduced that the durability of cotton fabric during washing is developed by means of treatment with nanosols containing polyvinyl acetate-based polymer. 相似文献

In this study, the tensile properties of flocked fabric after rubbing were studied. A statistical method was used to analyze the generated data. For this purpose, woven fabric was used as a substrate and an acrylic adhesive was applied on this substrate to hold the polyamide flock fibers forming flocked fabrics. A rubbing test was applied in dry and wet forms to the flocked fabrics before and after washing. The tensile properties of these rubbed flocked fabrics were determined. The regression models developed in this study explain the relationship between rubbing and the tensile strength of the flocked fabrics. The results from this experiment could be used in the development of flocked fabric as seat covers for the automotive industry. The warp tensile strength of a flocked fabric is generally higher than its weft tensile strength due to its higher substrate density in the warp direction. Also, the weft tensile elongation of a flocked fabric is generally higher than its warp tensile elongation due to its higher crimp ratio in the weft direction. When the stroke number increases, the warp and weft directional tensile strength and the elongation of a flocked fabric generally decrease. In addition, the stroke number of a flocked fabric before and after washing is low in its wet form compared to the dry form. The main reason is that the acrylic adhesive has poor wet properties. Results from the regression models were compared with the measured values. It was concluded that the method used in this study could be a viable and reliable tool. 相似文献

阻燃整理传统焙烘工艺易产生织物断裂强力损伤和色泽的变化,从而影响它的使用。为此采用潮态汽蒸方法对纯棉染色蓬盖布进行阻燃整理,讨论阻燃剂质量浓度、催化剂用量、汽蒸温度等因素变化对阻燃效果、织物断裂强力及色泽影响。采用正交实验分析法优化了汽蒸阻燃整理的工艺。实验结果表明,纯棉染色蓬盖布进行阻燃整理时采用潮态整理工艺与普通焙烘工艺相比,前者不仅能取得与焙烘工艺相当的阻燃效果,而且织物的其他性能指标如断裂强力等也明显优于焙烘工艺,尤以色泽更为显著。最佳工艺为:阻燃剂CFR:350g/L,催化剂C52:40g/L,汽蒸温度140℃,时间30min。 相似文献
