Guide to Fabric Thickness Test

 

When the fabric is subjected to a specified pressure, the vertical distance between the front and back sides is called the thickness, generally expressed in millimeters. Fabric thickness has a great influence on the wearing properties of the fabric. For example, the fastness, warmth retention, breathability, windproofness, stiffness and drape of the fabric are all related to the thickness of the fabric to a large extent.

Precautions for fabric thickness testing

  • When replacing the presser foot or when the instrument is not used for a long time, please place a protective rubber pad between the presser foot and the reference plate to protect the measuring surface from damage.
  • After each experiment, the power switch should be turned off and the power plug of the instrument should be pulled out of the power socket.
  • Clean and maintain the instrument well, and add a small amount of clock oil regularly.
  • Carry out regular instrument calibration as needed to ensure the accuracy of instrument measurement values.
  • When the instrument is not used for a long time, the battery should be removed to avoid leakage.

Influencing factors in fabric thickness testing

Fabric thickness is generally measured using a fabric thickness meter. There are many factors that affect the thickness of the fabric, such as the linear density of the yarn, the structure of the fabric, the degree of buckling of the yarn in the fabric, and the tension during production and processing. In addition, such as the area of the presser foot selected during the test, the pressure and effect applied Time, etc., all have an impact on the measured thickness.
a) The thickness of the fabric increases as the area of the presser foot increases.
b) The thickness of the fabric decreases as the applied pressure increases.
It can be seen that the fabric thickness is a conditional value. The thickness values obtained by selecting different presser foot areas, applying different pressures and different reading times are different. Generally, the measured thickness of blankets and pile fabrics changes greatly, while the thickness of coarse cloth and canvas fabrics has smaller changes. Therefore, when measuring fabric thickness, the presser foot area should be selected according to the standard recommended value, and the applied pressure value should be based on the material technical conditions or mutual agreement, and the selected presser foot area and applied pressure value should be noted on the test report.
When producing and processing fabrics, the thickness and density of the fabric can be adjusted by controlling the yarn density and weaving method of the fabric. By adjusting the yarn density of the fabric, fabrics of different thicknesses can be achieved. At the same time, different weaving methods will also affect the thickness and density of the fabric.

Digital Thickness Gauge for Textile

YG141D Series Digital Thickness Gauge for Textile is used to determine the thickness of textiles when under a specified pressure.
Related standards are as follows: ISO 5084, ISO 9073-2 (normal nonwovens), GB/T 3820, and GB/T 24218.2 (normal nonwovens).

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

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

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
