Problems solved by technology

[0003] In essence, the above-mentioned methods are all relying on manual counting methods, but there are many disadvantages in relying on manual counting methods, such as: too many fibers in the yarn, manual counting is very error-prone, or manual counting Takes too long and is inefficient
Moreover, for some cases where the number of fibers in the cross-section of the yarn is not fixed, multiple tests are required to take the average value, which makes the whole test process more cumbersome and increases the cost of testing the number of fibers in the yarn.

Embodiment 1

[0018] Embodiment 1: the test method of fiber root number in yarn

[0019] Step 1, using a biotome to cut the yarn to obtain 20 segments N of short segments of yarn with a length of 10 μm;

[0020] Step 2: Take 20 short pieces of yarn and place them in the same purification bottle. The purification bottle is made by a complete set of technological processes such as cleaning with high-precision ultrasonic cleaning machine, thousand-level clean air shower, drying and sealing, so that the purification bottle The cleanliness reaches NAS1638-1 level. Pour the liquid solvent into the purification bottle to immerse the short segments of the yarn, and stir until all the short segments of the yarn are fully dispersed in the liquid solvent, wherein the liquid solvent is distilled water or an organic solvent whose density is less than that of each fiber in the short segment of the yarn;

Abstract

The invention discloses a method for testing the number of fibers in yarns. The method for testing the number of fibers in the yarn comprises the following steps of cutting yarns by adopting a slicer,so that N sections of yarn short sections with regular length is obtained; placing the N sections of yarn short sections in the same purification bottle, pouring the liquid solvent into the purification bottle to immerse the short sections of the yarn, and stirring until all the yarn fragments are fully dispersed in a liquid solvent; and putting the liquid in the purification bottle into a liquidparticle counter, reading the number of fibers in the purification bottle displayed by the liquid particle counter, wherein the number of the fibers in the purification bottle is recorded as M, the number of the fibers in the yarns is A, and A is equal to M / N. The test method is high in accuracy and time-saving and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing, in particular to a method for testing the number of fibers in yarn. Background technique [0002] At present, manual counting method and microscope method are mainly used for testing the number of fibers in staple fiber or filament yarn. Among them, the manual counting method is: intercept a section of yarn, place it on the fleece board, separate the fibers by dialing the needle, and then count one by one to obtain the number of fibers in the yarn. The microscope method is as follows: intercept the cross-section of the yarn and place it on a glass slide, enlarge the image of the cross-section of the yarn through a microscope, count the number of fibers in the enlarged image, and obtain the number of fibers in the yarn. Similarly, the microscope can be replaced by a projector, and the cross-section of the yarn can be enlarged using the projector, and then the number of fiber...
