Testing Method for Oil Content of Man-Made Fibers

 

The ratio of the mass of non-volatile ester substances contained in fibers to the mass of the fiber is known as “Fiber Oil Content”.
The oil content of fibers is usually used as one of the important indicators for fiber quality evaluation, which is of great significance for the processing and application of fibers. The oil content of fibers is closely related to their spinnability. Fibers with low oil content are prone to generate static electricity, while those with high oil content are prone to sticking and entanglement, which can affect the normal operation of textile production and processing. Under the condition of meeting the requirements of anti-static and smoothness, the lower oil content of chemical fiber is better.

General Sampling Standards

  • Scattered laboratory samples should be taken out as needed, and should not be less than 50g;
  • The selection of the laboratory sample from short fiber batch samples shall be in accordance with GB/T14334, while the laboratory sample selection from long fiber batch samples shall be in accordance with GB/T 6502;
  • Do not select packaging that is accidentally damp, contaminated, scratched, or has been opened during transportation.

Rapid Oil Extraction Apparatus

Our product——the Rapid Oil Extraction Apparatus YG981B does use this extraction method. It is used to determine oil or grease content of various kinds of fiber (especially suitable for wool and its blend fabric) quickly. The applicable extraction solvents are petroleum ether, ethyl ether, dichloromethane, etc.

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
