纱线扭曲知识GydF4y2Ba

纱线:这是纱线和线程的一般术语。并具有强烈​​的连续条,包括单纱线和链。单纱:由短纤维处理,使沿轴向方向的短纤维或电线扭曲。PLY纱:它由两种或多个单纱制成,并扭曲。它的强度和耐磨性比单纱更好。同时,也可以以某种方式组合和扭曲层纱,以获得复合的扭曲纱。什么是扭曲?如果持有条带的一端,则旋转另一端,并且可以形成纱线,称为扭曲。对于短纤维,扭曲是使纤维带作为纱线的必要手段。通常有必要在扭曲之前将纤维凝结到纤维带中,并将纤维的外纤维挤出到内层中。 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...

织物耐药性的测试方法GydF4y2Ba

合理地和客观地评估织物的抵抗力,以促进纺织品的发展和生产以积极促进角色。由于连续摩擦,有许多用于脱落织物耐药性的测试方法,主要在日常生活和实际磨损和洗涤过程中进行模拟,因此,出现了织物表面的现象,因此设计了测试方法。不同的目标市场有不同的测试。方法,例如美国标准,欧洲标准,中国标准和客户标准,通常会根据出口,产品类型或买家选择适当的测试方法。常用的方法包括ICI药丸盒方法,Martindale Pilling方法,随机翻滚方法,弹性垫圈方法,圆形基因座药丸方法。应该注意的是,该药丸测试不仅限于上述测试。现在,有许多客户要求在洗涤后直接通过织物发夹进行评级,并且客户选择使用后洗涤样品。各种药丸测试方法评估织物对促进丸性能的抗性。ICI Pilling Box方法测试原理是三个方形样品,由从纬纱到纬纱的大小的正方形标本大小管子。在软木箱中,测试室每小时每小时3600旋转的数量,并将样品在评分盒中取出,并将织物与织物进行比较,而第一级是最差的。 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 ...

Ross Flex Resistance Test

1. Test purpose: Test the ability of the sole to resist incision growth after continuous twists and turns, that is, tolerance resistance. 2. Scope of application: It is mainly suitable for various types of tortuous sulfurized rubber sole, and also suitable for other various types of fluxless sole. 3. Test principle: Install the sole strip test piece on the SATRA TM60 Ross Flex Tester, so that its incision falls directly above the rotary axis center of the Ross Flex Resistance Testing Machine. Through the ISO 5423 Sole Bending Tester and turning test, the test piece was pulled to 90 ± 1 degrees on its shaft. After a certain number of tests, the length of the test tester was measured. Evaluate the quality of the test sole resistance performance with its incision growth rate. 4. Test Instrument: ROSS Flexing Tester: ROSS Flexing Tester is used to test the vertical flex resistance of rubber products, sole of shoes, and Foamed material suce PU、PVC、TPR. After flexing a certain times, then check the attenuation, damage and cracking degree to get the flexing resistance of the sample.
