Embodiment 1

[0093] 1. Sample

[0094] Model 5611 leather strap 110×100PCS (20mm wide and 5mm thick).

[0095] 2. Test steps

[0096] (1) Softness test at 20 mm from the end of the shaft hole: fix the leather strap 110 on the horizontal plane of the test platform 120 so that the short side shaft hole end of the leather strap 110 is 20 mm from the edge of the test platform 120, and then use the fixing fixture 130 Fix it on the test platform 120, install the test fixture 140 on the leather strap 110 at the force-bearing position of 120 (10 ± 1) mm away from the test platform, and then connect the tension meter 150 to the test fixture 140, and pull down the tension The gauge 150 makes the leather strap 110 bend to 30°~60°, and record the force value of the tension gauge 150 at this time (referred to as F 20 ), then restore the leather strap 110 to a horizontal position, and then measure the tension value bent to 30°-60° twice;

Abstract

The invention provides a method for detecting the softness of a leather watchband, which comprises the following steps: placing a leather watchband on a horizontal surface on the top of a test platform to make a position to be measured of the leather watchband located at the edge of the test platform; pulling down the leather watchband to bend the leather watchband to a preset angle, and recordingthe pull value for pulling down the leather watchband; restoring the leather watchband to the horizontal position; and determining the softness of the leather watchband by the pull value. The problemthat the softness of a leather watchband cannot be detected at present is solved. The softness of a leather watchband can be detected reliably and the softness level of the leather watchband can be determined, so as to ensure the wearing comfort of the leather watchband.

Description

technical field [0001] The invention relates to the technical field of leather strap detection, in particular to a method for detecting the softness of leather straps. Background technique [0002] The leather watch strap is a belt-shaped ornament specially made of genuine leather (cowhide, crocodile leather, etc.) and artificial leather for watches. The leather strap consists of a surface layer (usually dyed with various colors, the most common colors are black, brown, white and red, etc.), a middle layer (filling, usually made of poor quality, absorbent leather scraps), and a bottom layer. The leather layer (according to the waterproof performance can be divided into waterproof bottom skin and non-waterproof bottom skin), these three layers are usually combined by sewing and gluing. Because leather straps are in direct contact with human skin, their softness is directly related to the comfort of wearing leather strap watches, and indirectly affects the market acceptance a...
