2022年2月19日gydF4y2Ba测试原理:把sample-carrying管与测试样本到抗起球测试箱,启动ICI起球并妨碍测试仪,样品盒子里相互摩擦。同意的卷后,样品被评级。生产样品:1)预处理:如果需要预处理,样品可以水洗或干洗的方法由双方商定。(建议预处理保护摩擦表面的碉堡和剩余的样品管润滑剂或完成织物)2)减少4织物样本,样本的大小是125毫米* 125毫米,并削减另一个相同大小的布样所需的样本比较评级。两个样本沿纵向方面,向内折叠和2样本沿着水平前,向内折叠,用缝纫机缝距离12毫米的边缘。3)把缝合标本内而外,右边面朝外。减少6毫米端口在每个样品管。把样本在聚氨酯载体用PVC管和修复磁带(确保有6毫米裸露的聚氨酯,和胶带的长度不应超过1.5倍的周长聚氨酯管)。4)调试实验过程:(1)清理ICI抗起球箱。(2)把4套样品管放入盒子,盖坚决关闭盒子,将计数器设置为所需数量的旋转。 (3) Preset rotation times. Agreement times. Without agreement, 7200 revolutions for coarse fabrics and 14400 revolutions for fine imitation fabrics. (4) Start the pilling box, after the test, take out the sample, take out the suture, and grade the sample. Test Results Rating: The rating box should be placed in a dark room. Place the tested sample and an untested sample side by side in the middle of the test panel of the rating box in the longitudinal direction of the fabric (if the test sample is pretreated before testing, the control sample should also be pretreated. Correspondingly, if the test sample is not pretreatment, the reference sample shall be the unpretreated sample). Put the tested sample on the left and the untested sample on the right. Ratings are subjective and at least 2 ratings are recommended. The appearance of the sample and the corresponding grade are as follows: Series Status description 5 No change. 4 The surface is slightly fuzzed and/or slightly pilled. 3 Moderate fuzzing and/or pilling on the surface. Balls of different sizes and densities cover part of the surface of the specimen. 2 Visible fuzzing and/or pilling on the surface. Balls of different sizes and densities cover most of the surface of the specimen. 1 Severely fuzzed and/or pilled surface. Balls of different sizes and densities cover the entire surface of the specimen. Record the number of grades for each sample, and the result of a single person's rating is the average value of the grades for all the samples. The test result o...
2022年1月17日,gydF4y2Ba纱:纱和线程的通用术语。有很强的条幅,包括单纱和股。单纱:由短纤维处理,使短纤维或电线沿着轴向方向和扭曲。合股纱:它是由两个或两个以上的单纱和扭曲。其强度和耐磨性优于单纱。同时,合股纱也可以组合和扭曲以某种方式获得复合捻合股纱。捻线是什么?如果带的一端,另一端转动时,纱线就可以形成,称为扭曲。短纤维,扭曲的必要手段是使纤维纱条。通常需要浓缩的纤维成纤维带扭转之前,和外层纤维的纤维被挤压到内层。 Thereby, the strip is obtained in the longitudinal direction of the fibers. For long silk yarns and strands, twisted can form a tight structure that is not easily damaged by lateral force, and twisting can also form a variant wire and a fancy line. How many of the twisted and twisted direction not only affect the hand feel and appearance of the fabric, but also affect the intrinsic quality of the fabric. After the strip is twisted, the outer fibers produce a tilted helical roll back, the fiber torsional deformation, the gauze is tightly bored, and the structural form and mechanical physical properties of the fiber collective are changed. (As shown below) When there is an encirclement angle, the fiber has centripetal pressure on the yarn. The greater the encirclement angle, the greater the centripetal pressure. Due to the existence of centripetal pressure, the outer fiber is extruded to the inner layer, which increases the compactness of the yarn and the friction between the fibers, thus changing the structural form and physical and mechanical properties of the yarn, which is the essence of twisting yarn. Evaluation of yarn twist: Twist direction / twist / twist coefficient / twist shrinkage Twist direction: indicates the direction of twisting Twist direction refers to the inclined direction of the fiber in the single yarn or the single yarn in the strand after the yarn is twisted. It is divided into Z-twist and S-twist. After twisting, the twisting direction of yarn tends from the lower right corner to the upper left corner, and the inclined direction is consistent with the middle of "s", which is called s twisting or smooth twisting; The twist direction of yarn tends from the lower left corner to the upper right corner, and the tilt direction is consistent with the middle of "Z", which is called Z twist or backhand twist. Generally, Z-twist is used for single yarn and S-twist is used for ply yarn. The twist direction of the ply yarn is expressed according to the twist direction successively twisted. For example, the twist direction of single yarn with Z twist, initial twist with S twist and com...
2022年1月07gydF4y2Ba理性和客观地评价织物的抗促进纺织品的开发和生产,积极促进作用。测试方法有很多面料的抗起球性,主要是模拟在日常生活和实际磨损和洗涤过程中,由于持续的摩擦,因此,织物表面的现象出现,因此测试方法设计。不同的目标市场有不同的测试。方法,如美国标准、欧洲标准、中国标准和客户的标准,通常基于出口选择适当的测试方法、产品类型或买家。常用的方法包括ICI抗起球箱法、马丁代尔起球方法,随机翻滚法,弹性垫片法、织物起毛起球圆轨迹法。应该指出的是,抗起球测试不仅限于上述测试。现在有很多客户要求评级直接通过织物洗后的发夹,和客户选择使用事后样品。各种抗起球测试方法对促进评估织物的抗起球性能。ICI抗起球箱法测试原理是三个平方样本大小的平方标本的大小从纬纬,每个缝成管状的形状,和前面的面孔上分别设置管聚氨酯水分。在软木盒子,测试室翻转3600转/小时的数量,和样品取出评级箱和织物面料相比,第一级是最坏的打算。第五是最好的,当两个相邻两个层次之间的结果是,我评估一半。 Common test standards include ISO 12945-1, GB / T 4802.3, IWS TM 152. This method mainly simulates the fabric itself with its own uninterrupted friction, and the fans of the fabric and other pharmaceutically fangs. This test method can be applied to all types of fabrics, but the main domestic market or export to the European market is using this method to test the pilling performance. AVENO related products: AG05 ICI Pilling and Snagging Tester Martindale Pilling method The test principle is to take three pairs of circular samples from the fabric, which are loaded in the upper and lower clamping devices. Under the slight pressure, the sample itself rubs each other, and rubbed by the Lissajous, after a certain number of revolutions, Samples are compared with the original or standard samples of the rating box, and the the worst level 1, level 5 is the best, and when the results are interposed between two adjacent two levels, it can be evaluated as half level. This method is applicable to all types of fabrics, but it is more applied to woven fabrics. It mainly simulates the pilling condition after frequent friction between fabrics. AVENO related products: AG04 Martindale Abrasion and Pilling Tester Random Tumble method The experimental principle is to take ...
