Problems solved by technology

In reality, one side of the intimate clothing fabric adheres to the skin surface after sweating, and the other side is in direct contact with the air in most cases. Therefore, there is a big gap between the measured results of this method and the real situation, and it cannot reflect the stickiness of sweaty fabrics. the actual situation
[0007] In summary, there is currently no suitable method to objectively and effectively characterize the binding properties of skin stretching in human body movement after sweating by close-fitting fabrics

example 1

[0081] Fabric sample: 100% shrink-resistant wool knitted fabric, weft plain stitch, transverse density 95.0 ( / 5cm), longitudinal density 105.0 ( / 5cm), unit area weight 1.56g / cm 2 , cut 5 rectangular samples, the size of which is 20.0cm×5.0cm.

[0082] Test each sample according to the above steps [1] to [8], wherein the test parameters set in step [4] are: moving speed 200mm / min, skin area 24.00cm 2 , The displacement range is 0~80mm. After the test of 10 samples is completed, the test curve displayed on the main test interface of the computer is as follows: Figure 5 As shown, the test indicators and statistical data are shown in the table below.

Abstract

The invention relates to a textile fabric wet motion viscous deformation behavior characterization method and device, and the method comprises the steps: firstly, fixing two ends of a strip-shaped fabric sample after liquid absorption under certain in-plane tension, keeping the middle in a horizontal suspension state, then enabling artificial skin with a horizontal surface to be in contact with the lower surface of the fabric sample, adhering to each other to drive the artificial skin to translate from one end of the fabric sample to the other end at a constant speed, recording tangential adhesion measured along with the change of displacement or time to obtain a tangential adhesion-displacement (or time) curve, and finally obtaining a characterization index according to the curve; the device comprises a control module (comprising a force sensor) and a test module (consisting of a sample clamping system and a traction system), the sample clamping system is used for clamping and fixing two ends of the fabric sample; the traction system is used for driving the artificial skin to translate. The method and the device are simple, and the wet motion viscous deformation behavior of the textile fabric can be well represented.

Description

technical field [0001] The invention belongs to the technical field of testing methods for textile fabrics, and relates to a method and a device for characterizing the deformation behavior of textile fabrics in wet state kinematic viscose. Background technique [0002] In a hot environment, or after a lot of exercise, people will always sweat a lot so that the underwear is soaked in sweat and sticks to the skin. This discomfort is more obviously caused by the sense of restraint on the human body caused by the sticky fabric that cannot be stretched synchronously with the skin when a person is exercising. Textile fabric enterprises have taken many measures in terms of fabric design, processing, finishing, etc., in order to overcome or weaken the restraint and discomfort caused by sweat and sticky body of close-fitting fabrics. However, there is currently no reasonable and feasible method to characterize the deformation behavior of fabrics in wet state and the degree of restra...
