Method and device suitable for measuring fluffing and pilling amount and abrasion amount of textile

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 ...

AI Technical Summary

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

[0008] 2. The friction time of the instrument is long, the sample area for the test is small, and the representativeness is poor

[0009] 3. The error of visual rating or weighing rating after friction is large

[0010] 4. Raw materials with different fineness and blending ratio have different densities with different knitting machines, so it is difficult to formulate feasible standards

[0011] 5. The abrasive used can only use felt cloth imported from the UK, which is expensive and difficult to adapt to the friction requirements of different raw materials

[0013] Since it is only a static evaluation of the fabric, and it is aimed at the evaluation of the pilling results, it lacks objectivity and intuition

On the other hand, the friction time of the instrument is long, the area of ​​the woven piece used for the test is small, and the representativeness of the sample is poor. After friction, there are relatively large errors in both the qualitative visual method and the quantitative cutting hairiness and hairball weighing method.
