Measuring device and method for apparent fluffing and balling as well as abrasion loss of yarn

Abstract

The invention relates to a measuring method and a device for apparent fluffing and balling as well as abrasion loss of a yarn. The device comprises a yarn winding mechanism with a yarn grinding function, a yarn grinding mechanism with controllable friction pressure, a yarn feed mechanism with adjustable tension, a static and clipping mechanism, a hair bulb and hair feather collection mechanism, an optical measuring system for instant observation of yarn sample fluffing and balling shape and quantity, a data acquisition and control system and a computer. The method comprises the steps that the hair feather significance, the hair bulb shape and the hair bulb quantity of the yarn are immediately measured after a yarn sample is formed by winding the yarn through equal-tension close packing; friction fluffing and balling sampling is performed; and the hair feather significance, the hair bulb quantity, the hair feather and hair bulb abrasion, and the hair feather and hair bulb maintenance quantity of a yarn grinding sample in a process and in a final state are measured synchronously. The device is ingenious and practical in structure, and takes measurements precisely and quantitatively, the in-situ measuring device and the method are multipurpose, can measure multiple indexes, can be used for comprehensive evaluation of the yarn fluffing significance, the balling quantity and shape, the abrasion fiber quantity, the fluffing resistance, and the balling resistance, and can also be used for estimating fluffing and balling grades of fabric.

Description

technical field [0001] The invention relates to a measuring device for the apparent pilling and abrasion of yarns, and an evaluation method for predicting the pilling resistance of textiles by using the device, which 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 roller 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 to occupy an area, and it must be equipped with knitting mac...

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 test fabric is small, and the representativeness of the sample is poor. After friction, the errors of both the qualitative visual method and the quantitative weighing method of cutting feather and badminton are relatively large.
