纱线捻度知识gydF4y2Ba

纱线:是纱线和线的总称。并具有较强的连续条状,包括单纱和股。单纱:由短纤维加工而成,使短纤维或丝沿轴向缠绕而成。股纱:由两根或两根以上的单根纱线组合并捻成。其强度和耐磨性均优于单纱。同时,还可以将股纱按一定的方式组合捻成复合捻股纱。什么是扭转?如果将带材的一端握住,另一端旋转,就能形成纱线,称为捻丝。对于短纤维,捻丝是将纤维条制成纱线的必要手段。一般需要将纤维压缩成纤维条后再捻制,将纤维的外层纤维挤压成内层。 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...

织物抗起球性的试验方法gydF4y2Ba

合理客观地评价织物的耐候性,对促进纺织品的发展和生产具有积极的促进作用。面料抗起球性的测试方法有很多,主要是模拟在日常生活和实际的穿洗过程中,由于不断的摩擦,从而出现面料表面起球的现象,因此设计了测试方法。不同的目标市场有不同的测试。方法,如美国标准、欧洲标准、中国标准、客户标准等,通常根据出口、产品类型或买家选择合适的测试方法。常用的起球方法有ICI起球箱法、Martindale起球法、随机转鼓法、弹性垫片法、圆形轨迹起球法。需要注意的是,起球试验不仅限于上述试验。而且现在有很多客户要求洗后直接通过面料的发夹进行评级,客户选择使用洗后样品。各种起球测试方法,以评估织物对促进起球性能的阻力。ICI起球箱法测试原理是从纬线到纬线,用一个大小相同的方形试样,将三个方形试样分别缝成管状,正面分别设置在聚氨酯吸湿管上。在软木盒内,以每小时3600转的次数翻转试验箱,在评定箱中取出样品,将织物与织物进行比较,一级最差。第5层是最好的,当结果在两个相邻的两层之间时,我求一半。 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 ...
