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...
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 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...
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...
This machine can be used to test the bursting strength and height of woven, knitted, non-woven fabrics, paper or sheets. The instrument uses hydraulic blasting to act on a specific area of rubber film...
1. Each time you turn on the instrument and start a new set of tests, you must press the reset button to restart the instrument, otherwise the data processing will be incorrect. 2. When the instrument...
The needle flame test machine uses a needle burner of specified size (Ф0.9mm) to pass a specific gas (butane) to burn the sample at a 45° angle in a regular and directional manner, and observes whethe...
Take the fabric stretching function as an example: 1. Operation adjustment (1) Clamping distance adjustment Before the instrument tensile test, the clamping distance between the upper and lower clamps...
