The testing items in the textile testing laboratory are divided into fiber testing, yarn testing, and fabric testing according to material classification. In the following content, we will introduce the relevant information on fabric testing according to the different properties…
We usually divide fibers into natural fibers and man-made fibers. Fiber samples are generally available in three forms: ① Loose fiber; ② A yarn may be contain one fiber type or multiple fiber types; ③ Woven or knitted fabrics may…
As an important production equipment of cotton mill, roving frame belongs to the preparation process from combed sliver to spinning into yarn in the production process. Roving production is the last of the preparatory stages for spinning. The tasks of…
Fiber strength refers to the ability of fiber to resist external damage, which largely determines the durability of textile products. Common indicators Fiber strength: Absolute strength, the maximum load that a fiber material can bear when it is stretched to…
A cotton ginning machine is used to process cotton, primarily to remove seeds and foreign matter, making cotton a raw material for the textile industry. It can greatly improve processing efficiency and product quality, and is one of the indispensable…
Fiber length directly affects the processing performance and practical value of the fiber and reflects the quality and performance of the fiber itself, so it is one of the most important indicators of the fiber. Fiber length definition Natural length:…
Rotor spinning working principle Rotor spinning is a new spinning methods, this spinning method belongs to the category of open-end spinning. Rotor spinning does not use spindles, mainly relying on opening roller, rotor, false twisting device and other components. The…
Fiber fineness refers to the thickness of the fiber. Fineness is one of the important morphological dimensions and quality indicators of fibers. Fiber fineness is closely related to spinning process and yarn quality, and directly affects fabric style. Fiber fineness…
Ring spinning is a mechanical spinning method in which the spindle, the steel ring, and the traveler are twisted, and the rollers are used for drafting. Introduction Ring spinning is currently the most widely used spinning method in the market.…
The roving frame is the main equipment of cotton spinning, and it is also one of the most complex equipment. The quality of the roving frame directly affects the physical performance of the yarn, such as evenness, weight unevenness, strength,…
Draw frame is applicable for drafting fibers of bending cotton sliver to be straight and improve the degree of uniformity of cotton sliver through combining. The importance of draw frame After the cotton has been opened and carded, if the…
How to process the disorganized and horizontally closely connected fibers into vertical order and smooth yarn with certain requirements, it is necessary to turn the block fiber into a single fiber state, completely remove the horizontal connection of the fiber…
