Problems solved by technology

[0003] 1. It takes a lot of time to occupy an area, and it must be equipped with knitting machines of various needle sizes, and manual knitting is required
[0004] 2. After the sample is rubbed, it is evaluated by manual visual inspection, and the error is large
[0005] 3. At present, silicone is widely used in the finishing of knitted fabrics. After the woven sheet with silicone rubs against the cork board in the drum, the cork board is stained, and the cork board becomes smooth quickly, and the friction force gradually decreases until it disappears. Seriously affect the accuracy of the test and the reproducibility of the test
[0007] 1. It takes a lot of time to occupy an area, and it must be equipped with knitting machines of various needle sizes, and manual knitting is required

Embodiment 1

[0096] Using the device of the present invention, such as Figure 1~3 As shown, the measurement of the process friction sample in the first step to the third step is done for the pilling of the all-wool woven fabric whose yarn count is Nm48 / 2, and its measurement condition parameters and actual measurement results are shown in the following table embodiment 1 One column and the process measurement curve of the third step are shown in Figure 4 . The asymmetric back and forth rotation of the cloth sample cylinder 1 is adopted, that is, the advancing angle is 60°, and the retreating angle is 55°; the supporting reciprocating movement distance is 6cm, so that the friction block 21 can gradually move the fabric on the cloth sample cylinder 1. Ru curve friction. From the actual measurement results, it can be seen that the final state of the all-wool woven fabric after wear is more fuzzy, the average hairiness length is 5.6mm, the density is 0.175, and the hairiness significance i...

Embodiment 2

[0098] Using the same method and device as in Example 1, the cashmere knitted fabric with a yarn count of Nm28 / 2 is pilling according to the full set of measurement and calculation results from the first step to the fourth step, and the initial sample of the measured cloth sample is obtained. , the fuzzing and pilling of the process friction sample and the final state friction sample, one by one analysis and the comprehensive evaluation of the final results, the measurement condition parameters and the actual measured final state friction sample results are shown in the column of Example 2 in the table below. The symmetrical rotation in the reciprocating rotation of the cloth sample cylinder 1 is adopted, that is, the rotation in which the advancing angle of forward rotation is equal to the retreating angle of reverse rotation. The cashmere knitted fabric on cylinder 1 is subjected to constant Lissajous curve friction, and its friction number N2 is only 2 / 3 of that of Example 1...

Embodiment 3

[0100]Using the same method and device as in Example 1, the pilling of wool polyester sweaters with a yarn count of Nm32 / 2 is based on the fourth step of measurement under the same experimental conditions and the influence of the first step of the package sample. Combined with the calculated results, a comprehensive evaluation of the pilling performance of the tested fabric sample is obtained. Its measurement condition parameters and actual measurement results are shown in the column of Example 3 in the following table. The drum 11 is not moved and the friction block 21 is used for reciprocating translation friction sample preparation. The supporting reciprocating movement distance is 2.5cm. Every time 50 times of reciprocating grinding are completed, it is rotated 90° until 20 cycles of 1000 times of friction. Example 1 has the same number of frictions, but different trajectories. It can be seen from the actual measurement results that the final friction-like fluffing of the...

Abstract

The invention relates to a method and a device suitable for measuring the fluffing and pilling amount and abrasion amount of a textile. The device is composed of a cloth sample barrel for coiling and clamping the textile, a rubbing mechanism for fluffing and pilling a cloth sample, a mini-type dust collector for collecting fallen fibers and fuzzy balls, an electrostatic electrode for assisting filoplume to be vertical, a collector for shearing and collecting the fuzzy balls and the filoplume, an optical measurement system for observing the fuzzy balls of the cloth sample, an electronic scale for weighing the weight of the filoplume fuzzy balls, a data acquisition and control system and a computer. The measurement method comprises the following steps: after coiling the cloth sample by equal tension, immediately measuring the filoplume significance as well as the quantity, form, size and distribution of the fuzzy balls; rubbing, fluffing and pilling to prepare a sample and synchronously measuring the process and measuring the filoplume significance of a final rubbing sample, the fuzzy ball quantity, the abrasion to the filoplume fuzzy balls and the remaining amount. The device and the method are ingenious, practical, accurate and quantitative; in-situ measurement for one machine with a plurality of purposes and one measurement process with a plurality of indexes is realized; the device and the method can be used for preparing the sample by fluffing and pilling the textile, measuring the fluffing and pilling amount and abrasion amount of the textile, and carrying out comprehensive analysis and evaluation.

Description

technical field [0001] The invention relates to a method and device suitable for measuring the quality of fabric pilling and hairiness and wear, and an evaluation method for predicting the pilling resistance of fabrics and the measurement of wear substances. A measuring device belongs to the technical field of textile quality evaluation and testing. Background technique [0002] Pilling is a major appearance defect of the fabric, which is gradually exposed during wearing and use. Commonly used fabric pilling performance measurement devices and instruments are: domestic YG511 pilling tester, British ICI pilling tester, the basic principle and structure are the same. It wraps the fabric to be tested on a rubber roller, and puts it into a hexahedron drum whose inner wall is a cork board and rolls freely. After taking it out at regular intervals, compare it with the photo standard sample and evaluate the grade. The disadvantages of this method are: [0003] 1. It takes time ...
