Embodiment 1

[0067] Embodiment 1: no twisting

[0068] The test sample is two kinds of PTFE fibers, the linear density is about 450dtex, the abrasive on the grinding roller is 500 mesh water sandpaper, and the grinding roller is a smooth cylindrical grinding roller with a diameter of 2cm. The grinding roller does not rotate, but only reciprocates. The rubbing speed is 60 times / min, the rubbing distance is 5cm, the rubbing angle is 120°, the mass of the weight on the U-shaped hook is 45g, and the fiber is not twisted. Wrap 500 mesh water sandpaper on the surface of the grinding roller, and the sample fiber according to figure 1 Wrap it on the abrasion resistance tester as shown, and carry out 5 tests according to the above parameters. The test conclusions are shown in Table 1. It can be seen from Table 1 that the number of reciprocations of the grinding roller when the 1# PTFE fiber is broken is greater than the number of reciprocating times of the grinding roller when the 2# PTFE fiber is...

Embodiment 2

[0072] The test sample is 1#PTFE fiber, the linear density is about 450dtex, the abrasive on the grinding roller is 500 mesh water sandpaper, and the grinding roller is a smooth cylindrical grinding roller with a diameter of 2cm. The grinding roller does not rotate, but only reciprocates. The rubbing speed is 60 times / min, the rubbing distance is 5cm, the rubbing angle is 120°, and the mass of the weight on the U-shaped hook is 45g. image 3 Twisting is carried out as shown, and the fiber twists are 0 twist, 50 twist, and 100 twist respectively. Wrap the 500-mesh water sandpaper on the surface of the grinding roller, and the sample fiber according to figure 1 Wrap it on the abrasion resistance tester as shown, and carry out 5 tests according to the above parameters. The test conclusion is shown in Table 2. As can be seen from Table 2, the number of reciprocations of the grinding roller when the 1# PTFE fiber breaks without twisting is greater than the number of reciprocations...

Abstract

The invention discloses a continuous organic fiber wear resistance tester, which is simple in structure, convenient to operate and high in test efficiency, can test the wear resistance of continuous organic fibers and different abrasives under the action of different friction speeds and different tensions, can change the test conditions such as friction distance, friction angle and grinding rollertype for testing. and can conduct a wear resistance test on the continuous organic fibers after twisting, so that the wear resistance of the organic fibers under the twisting condition can be more accurately represented. Not only can a disc do circular motion to drive a crank connecting rod so as to drive a sliding block to further drive a grinding roller to do reciprocating motion, but also theabrasion resistance is evaluated by utilizing the reciprocating motion times of the grinding roller in the sliding abrasion mode, the abrasion resistance can be evaluated by rolling the rotation turnsof the grinding roller in the abrasion mode, and the wear resistance of various organic fibers in the production process and practical application can be simulated and evaluated more comprehensivelyand efficiently by characterizing the tension, broadening, hairiness amount and the like of the organic fibers.

Description

technical field [0001] The invention relates to the technical field of test and evaluation of organic fibers, in particular to an abrasion resistance tester for continuous organic fibers. Background technique [0002] With the use of shuttleless and high-speed looms and the systematic development of fibers, fibers become easier to break during the weaving process, and the breakage of fibers will affect the continuous work of looms and the quality of fabrics. Therefore, the abrasion resistance of the fiber will affect its weavability. The higher the abrasion resistance, the better the processability of the fiber, and the more durable the woven fabric. Therefore, the abrasion resistance has become an important indicator of fiber performance. During the weaving process, organic fibers will mainly produce friction in various directions and properties with the back rest, weft insertion device and dropper. In order to study the wear resistance of fibers, there are many researche...
