My country's current standard for leather shoe heels QB/T 3643-1999 "Leather Heel Surface" stipulates the wear resistance of the leather shoe heel surface using the standard method of GB/T 3903.2-1994...
Test standards: The fabric's color fastness to light and perspiration is tested using GB/T 14576-2009 "Textiles Color Fastness Test - Light and Perspiration Composite Color Fastness"; the pH value of ...
The main factors that affect the compressive strength of cartons are: ① raw material quality; ② moisture; ③ box type and flute type; ④ printing and opening; ⑤ processing technology. a. Raw material qu...
1.Scope This standard specifies the method of using a pilling box to determine the degree of pilling of fabrics without pressure. Comply with standards: GB/T 4802.3-1997 replaces GB 4802.3-84. This st...
Twist test principle: The twist is usually not evenly distributed on the entire yarn. When testing the twist, the sample should be taken 1 m away. Under the specified tension, clamp both ends of the s...
The hydrostatic pressure tester is suitable for measuring the water permeability performance of various fabrics and non-woven products that have been waterproofed, such as canvas, geotechnical materia...
The tensile strength of a button refers to the maximum load that a button on a textile garment can withstand when the deformation of its seam with the fabric reaches a certain degree or the button bre...
The tensile testing machine is an instrument that can provide upward and downward adjustable speed motion. Cooperating with a force sensor and a microcomputer or computer, it can test rubber, plastics...
The ICI pilling tester is suitable for detecting the pilling phenomenon caused by friction on the fabric surface without pressure, and is suitable for woven and knitted fabrics. Meet the standards: AS...
Measuring principle of tensile machine: 1.The force value of the tensile testing machine is measured through a load cell, amplifier and data processing system. Under the premise of small deformation, ...
This paper mainly uses the Taber wear tester to conduct actual testing and analysis on the wear resistance of common shoe upper materials such as soft leather, artificial leather, synthetic leather, m...
The tensile testing machine has many functions and can detect the strength of various materials. When the instrument encounters problems and malfunctions, the following methods can help you. One. When...
