1 Scope

This document describes a test method for the determination of the suppleness of hair products by force testing. This document applies to straight hair products with a length of not less than 310mm.

2 Normative reference documents

The contents of the following documents constitute essential provisions of this document through normative references in the text. Among them, the dated quotations For undated referenced documents, only the version corresponding to that date applies to this document; for undated referenced documents, the latest version (including all amendments) applies to this document. GB/T 6529 Standard atmosphere for humidity conditioning and testing of textiles GB/T 8170 Numerical rounding rules and representation and determination of limit values GB/T 23166 Hair product terminology GB/T 29256.5-2012 Textile woven fabric structure analysis method Part 5.Determination of linear density of yarn removed from the fabric

3 Terms and definitions

The terms and definitions defined in GB/T 23166 and the following apply to this document. 3.1 Compliance The softness and smoothness of hair products under specified conditions is expressed by the softness coefficient in the force measurement method. 3.2 retardantforceofhair Under specified conditions, the average resistance experienced by a standard hair comb as it moves downwards at a uniform speed in the hair product sample. 3.3 centerheight In the vertical plane, clamp the two ends of the specified length of hair to bend it into a natural heart shape. The distance between the lowest point of the heart shape and the clamping point. 3.4 Compliance coefficientcomplianceratio Under the unit hair linear density and unit hair bundle mass, the ratio of the hair suspension center height to the hair bundle blocking force.

4 Principles

The height of the suspension center and the blocking force of the hair bundle were measured, and the compliance coefficient was used as an index of compliance. Arrange the sample so that both ends are neat and of a certain length. A hair bundle of a certain degree and quality is held at one end and hangs down naturally at the other end. After combing it a little, insert a standard hair comb into the sample and lower it along the sample at a constant speed. Move, and measure the resistance experienced by the standard hair comb during the downward movement. By measuring the height and linear density of the hair strands and the quality of the hair strands, the smoothness is calculated. coefficient. ......
