Bursting Strength Test and Related Equipment

 

When fabrics are worn or used, they are often subject to concentrated loads perpendicular to the plane of the fabric. The fabric bulges and expands from one side until it breaks, such as at knees, elbows, shoe uppers, glove fingers, and sock toes. This phenomenon is called bursting or bursting. Since its force mode is multi-directional force damage, this test is particularly suitable for knitted fabrics, three-way fabrics, non-woven fabrics and parachute fabrics.

Basic principles of bursting performance testing

(1) Steel ball method: A sample of a certain area is clamped in a circular sample clamp on a fixed base. The spherical ejector pin vertically pushes against the sample at a constant moving speed, causing the sample to deform until it breaks. The bursting strength was measured.
(2) Hydraulic method: Clamp a sample of a certain area on an extendable diaphragm, and apply liquid pressure below the diaphragm. Then, the volume of the liquid is increased at a constant speed to expand the diaphragm and the sample until the sample ruptures, and the bursting strength and bursting expansion are measured. The test sample is ruptured by hydraulic pressure acting on the rubber eardrum. It is used to test the maximum pressure value and bursting height of knitted, woven, paper, and cardboard paper when they rupture.
(3) Air pressure method: Clamp the sample on an extendable diaphragm, and apply gas pressure under the diaphragm. Then, the gas volume is increased at a constant speed to expand the diaphragm and the sample until the sample ruptures, and the bursting strength and bursting expansion are measured.

Bursting strength tester

Bursting Strength Machine YG032D
It is used for testing fabric bursting strength and expansion such as knitted fabrics, non-woven fabrics, leather etc.
Bursting Strength Machine Method: The sample is held at an extension on the diaphragm, below the diaphragm pressure (manual liquid pressure, electric liquid pressure, gas pressure, etc.), making the diaphragm and sample expansion, increasing the pressure at a constant speed, until the broken sample is measured for burst strength or burst expansion ratio.

Twist Test Methods and Influencing Factors

Image
  Twist test is an important part of yarn inspection. It is related to the strength, elongation, appearance, style, etc. of yarns and fabrics. Different yarns have different structural characteristics, and their twist testing methods are also different. Basic concept To understand twist testing, you must first understand what twisting is. Twisting is a necessary condition for yarn formation. Short fibers can be made into yarns with certain physical and mechanical properties through twisting; filaments often need to be twisted in order to increase the tightness between single filaments, facilitate processing, and improve fabric properties. Number of twists Twisting is to cause two cross-sections of parallel straight fiber slivers to rotate relative to each other. The number of relative rotations of the two cross-sections is called the number of twists. Twist Twist refers to the number of twists per unit length of yarn . Twist coefficient In actual production, the twist coefficient is of

Combing Process in Spinning

Image
Before processing cotton, wool, and silk fibers into fabrics, the process of removing impurities and short fibers in the fibers with a combing machine is called combing. The texture, washability and durability of the fabric produced through this process are greatly improved compared with carded fabrics. The following introduces the composition of the combing machine and the combing process. The kinematic coordination relationship of the main parts on the combing machine is indicated by a dial. The disc is mounted on the combing machine and rotates synchronously with the cylinder, which is generally called the indexing disc. The index plate is divided into 40 equal parts along the circumference, and each equal part is 9°, which becomes one index. The working cycle refers to the time interval between the combing cylinder of the intermittent combing machine corresponding to the two actions of combing the whiskers. That is: the first row of needles in the combing cylinder goes to the botto

Garment Dyeing-Special Dyeing Method In Textile

Image
Garment dyeing is a relatively special dyeing process for textiles and garments. Many people may not know much about this dyeing process. In the impression of most people, textile and clothing products are dyed in the fabric period, and garment dyeing is a dyeing process that breaks people’s cognitive limitations on textile dyeing. ​What is garment dyeing ​Garment dyeing means that dyeing the one not in the fabric type but in the garment type itself. The garment type mentioned above include socks, towels, sportswear, shirts, plush toys (without fillers), T-shirts, pants, bathrobes, handkerchiefs, bath mats, carpets, scarves, etc. The material of these garments can be wool, linen, silk and cotton of natural fibers. But most garments are made of cotton or a cotton-rich blends. Garment dyeing imparts vibrant colors to garments. The clothes such as denim garments, tops, sportswear and casual clothing with garment dyeing can provide a distinctive special effect. Garment dyeing method Garmen
