纱线捻度的知识gydF4y2Ba

纱线:是纱线和线的总称。并具有较强的连续条,包括单纱和股纱。单纱:由短纤维加工而成,使短纤维或丝沿轴向并捻。合股纱:由两根或两根以上的单纱混合并捻而成。其强度和耐磨性均优于单纱。同时,合股纱也可以按一定的方式组合加捻得到复合加捻纱。捻线是什么?如果条的一端被拉住,另一端被旋转,纱线就可以形成,这叫做绞合。对于短纤维,加捻是使纤维条成纱的必要手段。一般有必要在扭转前将纤维压缩成纤维条,并将纤维的外层纤维挤出到内层。 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...

织物耐起球性的试验方法gydF4y2Ba

合理性,客观地评估面料的抗性,促进纺织品的发展和生产积极促进作用。由于连续摩擦,有许多用于织物的丸剂抗药性的测试方法,主要是在日常生活期间和实际磨损和洗涤过程中,因此出现了织物表面的现象,因此设计了测试方法。不同的目标市场具有不同的测试。方法,如美国标准,欧洲标准,中国标准和客户标准,通常根据出口,产品类型或买家选择适当的测试方法。常用的方法包括ICI丸盒方法,Martindale丸法,随机滚筒法,弹性垫片方法,圆形轨迹丸法。应注意,丸剂测试不仅限于上述测试。现在有许多客户要求直接通过织物的发夹在洗涤后进行评级,并且客户选择使用洗涤后样品。各种丸试验方法,以评估织物的电阻,促进促进丸性能。ICI丸盒方法测试原理是三件方形样品,其尺寸由纬线的尺寸从纬线到纬线的尺寸大小,每个尺寸被缝合到管状形状中,并且前面分别设置在聚氨酯水分上管子。在软木塞中,测试室通过每小时3600转数翻转,并将样品在额定盒中取出,并且将织物与织物进行比较,并且第一级是最差的。 The 5th is best, when the result is between the two adjacent two levels, I evaluate half. 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 ...
