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...

织物抗药性的试验方法gydF4y2Ba

合理、客观地评价织物的耐水性,对促进纺织品的开发和生产起到积极的促进作用。面料抗起球性的测试方法有很多,主要是在日常生活和实际的磨损和洗涤过程中模拟,由于不断的摩擦,导致面料出现表面现象,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、中国标准和客户标准,通常根据出口、产品类型或买方选择适当的测试方法。常用的方法有ICI起球盒法、Martindale起球法、Random Tumble起球法、Elastic垫圈起球法、Circular Locus起球法。值得注意的是,起球试验不仅限于上述试验。而现在有很多客户要求直接通过水洗后面料的发夹来评分,客户选择使用水洗后的样品。采用各种起球试验方法来评估织物的抗起球性能。该测试原理是三件方形样品,由纬线到纬线的尺寸的方形样品进行定尺,每件都缝制成管状,正面分别设置在聚氨酯湿气管上。在软木盒内,以每小时3600转的次数对测试箱进行翻转,然后在评分盒内取出样品,与织物进行比较,第一级为最差。第5个是最好的,当结果在两个相邻的水平之间时,我估计一半。 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 ...
