2月19日，2022年GydF4y2BaTest principle: Put the sample-carrying tube with the test sample into the pilling test box, start the ICI Pilling and Snagging Tester, and the samples are rubbed against each other in the box. After the agreed number of rolls, the sample is taken out for rating. Production of samples: 1) Pretreatment: If pretreatment is required, the samples can be washed or dry cleaned by the method agreed by both parties. (Pretreatment is recommended to protect the friction surface of the pillbox and the sample tube from residual lubricants or finishes on the fabric) 2) Cut 4 samples from the fabric sample, the size is 125mm*125mm, and cut another cloth sample of the same size as the comparison sample required for the rating. Two samples were folded inward along the longitudinal front, and 2 samples were folded inward along the horizontal front, and sewed with a sewing machine at a distance of 12 mm from the edge. 3) Turn the sutured specimen inside out, right side facing out. Cut 6mm ports on each end of the sample tube. Put the sample on the polyurethane sample carrier tube and fix it with PVC tape (ensure that there are 6mm bare ends of the polyurethane, and the length of the tape should not exceed 1.5 times the circumference of the polyurethane tube). 4) Debugging Experiment procedure: (1) Clean the ICI Pilling Box. (2) Put the 4 sets of sample tubes into the box, close the box cover firmly, and set the counter to the required number of rotations. (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...
Jan 17, 2022纱线：这是纱线和螺纹的一般期限。并且具有强大的连续带材，包括单个纱线和股线。单纱：由短纤维加工，使短纤维或沿轴向的线和扭曲。PLY纱线：它由两种或更多的单纱组成，组合和扭曲。它的强度和耐磨性优于单纱线。同时，帘布层也可以以某种方式组合并扭曲以获得复合扭曲的纱线纱线。什么是扭曲？如果保持条形的一端，则另一端旋转，并且可以形成纱线，称为扭曲。对于短纤维，扭曲是使纤维条作为纱线的必要方法。在扭转之前，通常必须将纤维压在纤维条中，并且纤维的外纤维被挤出到内层中。 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...
Jan 07, 2022理性、客观地评估阻力of the fabric to promote the development and production of textiles to actively promote the role. There are many test methods for Pilling Resistance of fabrics, mainly simulated during daily life and actual wear and washing process, due to continuous friction, Thus, the phenomenon of the surface of the fabric appears, and thus the test method is designed. different target markets have different tests. Methods, such as US standards, European standards, China Standards, and customer standards, usually select appropriate test methods based on export, product types or buyers. The commonly used methods include ICI Pilling Box method, Martindale Pilling method, Random Tumble method, Elastic gasket method, Circular Locus Pilling method.It should be noted that the pilling test is not only limited to the above test. and now there are many customer requirements to rating directly through the hairpin of the fabric after washing, and the customer chooses to use the post-washing sample. Various pilling test methods to assess the resistance of the fabric against the promoting pilling performance. ICI Pilling Box method The test principle is three pieces of square samples that are sized by a square specimen of sizes from the weft to the weft, each of which are sewn into a tubular shape, and the front faces are separately set on the polyurethane moisture tube. Within a cork box, the test chamber is flipped by the number of 3600 revolutions per hour, and the sample is taken out in the rating box and the fabric is compared to the fabric, and the first level is the worst. 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 ...
