Problems solved by technology

The traditional detection method has the following problems: First, the reagents used are different from human secretions in actual use.
Secondly, the wiping cloth is not a standard substance, and there is no quantitative index for the liquid retention rate, wiping force and wiping stroke of the wiping cloth
Again, the evaluation method of the test results is unreasonable. "Visual inspection of the color on the degreasing gauze is unqualified." This evaluation method is too hasty and obviously not suitable for evaluating the quality of bamboo mat products.
In summary, the existing detection methods for the color fastness of bamboo mat products have poor operability, poor reproducibility of test results, and are non-instrumental tests. The results of different testers vary greatly, and the evaluation of test results is unreasonable. Therefore, it is very important to solve the above problems

Embodiment 1

[0020] The present embodiment provides a method for detecting color fastness to water rubbing of bamboo mat products, comprising the following steps:

[0021] a. Prepare two pieces of bamboo mat product samples of about 200mm×80mm in the length direction and the width direction of the sample respectively, and several pieces of cotton friction cloth with a size of (50±2)mm×(50±2)mm and tertiary water;

[0022] b. Cotton rubbing cloth is placed in an environment with a temperature of (20.0±2.0) ℃ and a relative humidity of (65.0±5.0)% for more than 24 hours;

[0023] c. Carry out dry friction on the samples of bamboo mat products to be tested, use humidity-adjusted standard substances in the pressure range of 9N~15N, the clamping distance range of the sample holder is 2mm~15mm, and the friction stroke is (104± 3) 10 to 50 cycles of reciprocating friction under the condition of mm, the length direction and width direction of the bamboo mat products are tested once, and then the ...

Embodiment 2

[0028] Present embodiment allows different personnel to carry out reproducibility experiment to the present invention on the basis of embodiment 1, and test result is shown in the following table:

[0029]

[0030] It can be seen that the difference between the results of this example and example 1 is within 0.5 level, and the detection method meets the requirement of reproducibility.

Abstract

The invention relates to a method for detecting color fastness, in particular to a method for detecting color fastness to water and rubbing of bamboo mat products. The method comprises the steps of pre-treating a standard substance in a specific detection environment, wiping a to-be-detected sample in a dry friction mode and a wet friction mode with water, and then comparing and grading the testedstandard substance by using a gray scale card for assessing staining under a D65 light source to complete detection. The provided method for detecting color fastness of the bamboo mat products is simple and convenient to operate, high in precision and high in repeatability, has wide applicability and practical significance, and is an innovation of methods for detecting the color fastness of the bamboo mat products.

Description

technical field [0001] The invention relates to a method for detecting color fastness, in particular to a method for detecting color fastness to water rubbing of bamboo mat products. Background technique [0002] With the improvement of people's quality of life, the quality requirements for bamboo mat products are getting higher and higher. However, the quality of bamboo mat products on the market is uneven, and the color fastness of products will always fail in the sampling process. Case. Tracing it to its cause, it is mainly reflected in the two aspects that the product quality is not up to standard and the determination method of color fastness needs to be improved. While the market share of bamboo mat products is increasing, the proportion of consumers whose rights and interests are impacted due to unqualified color fastness is also increasing. Manufacturers of bamboo mat products have also suffered repeated setbacks due to product quality problems. Therefore, whether ...
