Description

Heart-shaped method fabric bending ring height tester

Technical Field

The invention belongs to the technical field of fabric bending performance testers, and particularly relates to a heart-shaped fabric bending ring height tester.

Background

The hand feeling is a key factor for determining the style of the fabric, quantitative measuring means for the hand feeling of the textile in the industry are enriched day by day, and indexes comprise softness, smoothness, cold and warm feeling, elasticity and the like. Among other things, the bending properties of the fabric have a significant effect on its softness. At present, relevant standards in the United states, Japan and China all have requirements on a test mode of textile bending performance, the bending performance test mode of the textile is mainly described through GB/T18318 in China, and the standards comprise means such as a slope method, a heart-shaped method, a Gray method, a cantilever method and a pure bending method, wherein the heart-shaped method is the simplest and most intuitive mode.

The method specifically comprises the steps of suspending and fixing a long-strip textile with a certain width on a tester in a heart shape, and representing the bending performance of the fabric by testing the height of a heart-shaped bending ring, wherein the larger the height of the bending ring is, the more easily the fabric is bent.

The current domestic universal equipment is a heart-shaped fabric stiffness meter from Nantong Macro laboratory instruments Co., Ltd. the mode is that a sample clamping copper plate is adopted to clamp a textile, so that the textile is heart-shaped and suspended, the height of a flat ruler is adjusted to be in contact with the bottom of a heart-shaped bending ring, and the height of the bending ring is read by the ruler.

At present, the device has applied for utility model patent with patent number 2013200099997. In the practical process, the following inconveniences exist in the equipment: the bending ring 1 is fixed on equipment through clamping of the 'sample clamping copper plate', and the 'sample clamping copper plate' is fastened through the eccentric wheel, so that when a sample is fixed, the sample must be bonded on the 'sample clamping copper plate', the sample is formed into a heart shape, and then the copper plate is fastened through the eccentric wheel, and then the height of the bending ring is measured. The clamping mode needs the matching operation of a heat-sensitive adhesive tape, a copper plate and an eccentric wheel, and the steps are complex and time-consuming; 2 in the height measurement process is traded in the bending, will remove the ruler, because the ruler subassembly is with opaque closed cyclic annular cover on taking the scale stand, the scale can receive to shelter from, makes the scale of the height that the ruler was located can not be read by the accuracy, influences the accuracy of test result.
