Towel softness testing method and testing device

Abstract

The invention provides a towel softness testing method and testing device. The towel softness testing method comprises the following steps: detecting a pressure value of a towel sample in real time; when it is detected that the pressure value is larger than or equal to a first preset pressure value, starting metering of linear displacement of the test pressing block, ending metering when it is detected that the pressure value is larger than or equal to a second preset pressure value, and recording the moving distance of the test pressing block as compression deformation; controlling the test pressing block to stop moving downwards, moving upwards by a preset distance according to a second preset speed, and timing; if it is detected that the pressure value is smaller than or equal to a third preset pressure value within the preset duration, stopping timing, recording the duration as the recovery duration, and recording the preset distance as the recovery length; and determining the softness of the towel according to the compression deformation amount, the recovery duration and the recovery length. According to the technical scheme, the technical blank of towel softness quality control, detection and evaluation is filled up, the quantification standard is unified, the measurement uncertainty is small, the data reproducibility is high and the influence of human factors is avoided.

Description

technical field [0001] The invention relates to the technical field of towel detection, in particular to a method for testing the softness of a towel and a device for testing the softness of a towel. Background technique [0002] Softness is a common technical index that people often use to evaluate towels. It is the feeling when the human body touches or pinches the towel. The difference in the manufacturing method, fiber material, and processing method of the towel will affect the softness of the towel. However, in related technologies, generally By touching the towel to be detected by hand and judging by touch, there are the following technical defects: [0003] (1) There is no special test device and no corresponding test method standards. For the softness test of towels that consumers focus on, there is no method, no ability to test, and the test results cannot be quantified, forming a gap in quality control, testing and evaluation . [0004] (2) There is a lack of un...

Problems solved by technology

[0003] (1) There is no special test device and no corresponding test method standards. For the softness test of towels that consumers focus on, there is no method and no ability to test. The test results cannot be quantified, forming a gap in quality control, testing and evaluation

[0004](2) Lack of unified quantitative standards, large errors, greatly affected by human factors, different people have different judgment standards, and the detection speed is slow
