Problems solved by technology

[0002] The traditional evaluation methods mainly rely on people's subjective feelings, and can get the ranking of softness, but the results of several evaluations are not comparable, and the softness of fabrics cannot be quantitatively evaluated.
Traditional evaluation methods are significantly affected by human subjective factors, the evaluation results are not accurate enough, and the evaluation cycle is long

Embodiment Construction

[0010] First, the fabric samples are conditioned for more than 24 hours under standard conditions, and then the corresponding parameter indicators are tested with the fabric style meter (KESF), a total of 12. Calculate the corresponding comprehensive value according to the formula (1), judge its softness range according to the size of the comprehensive value M, and complete the test.

[0011] for example:

[0012] (1) Select 1 / 3 twill cotton fabric for testing, fabric specifications: 19.4 / 2×48.6, 484×252, after testing its 12 physical parameters, use formula (1) to calculate, its M=3.54, according to the interval distribution, the fabric belongs to softness level 6, which belongs to the hardest level

[0013] (2) Select 2 / 2 twill wool fabric for testing, the fabric specifications are: 6.7 / 2×10.5, 401×392, after testing its 12 physical parameters, use the formula (1) to calculate, its M=-2.2, According to the interval distribution, the fabric belongs to the second level of so...

Abstract

The invention relates to an objective evaluation method of the flexibility grade of a woven fabric. The flexibility grade of the woven fabric is evaluated by utilizing a comprehensive evaluation value which is calculated according to a formula via the measurement of relevant physical parameters. The evaluation method depends on an objective testing result of physical properties relevant to the flexibility of the woven fabric, realizes the objective evaluation of the flexibility grade of the woven fabric and further specifies a flexibility evaluation system of fabrics.

Description

Technical field [0001] The invention designs an objective evaluation method for the softness level of woven fabrics. With the help of the test results of the physical properties of the woven fabrics, specific numerical values ​​are calculated through formulas, and the objective evaluation of the softness level of the woven fabrics is carried out according to the numerical values. Background technique [0002] The traditional evaluation methods mainly rely on people's subjective feelings, and can obtain the order of softness, but the results of several evaluations are not comparable, and the softness of fabrics cannot be quantitatively evaluated. Traditional evaluation methods are significantly affected by human subjective factors, the evaluation results are not accurate enough, and the evaluation cycle is long. Contents of the invention [0003] In order to improve the deficiencies of the traditional method for evaluating the softness of woven fabrics, this patent proposes...
