Frequently Asked Questions | FAQs

What is comb sorter diagram ?

A comb sorter diagram is a graphical representation of the combing process used in textile production. Combing is a process that is used to prepare carded or spun yarn for use in weaving or knitting by removing short fibers, knots, and other defects.

A comb sorter diagram typically shows the various components of a combing machine and how they work together to remove the unwanted fibers. The diagram usually includes a representation of the carding cylinder, the combing rollers, the doffer, and the waste bin.

The diagram may also show how the fibers are fed into the combing machine and how they are combed and sorted as they pass through the different components. The diagram may also include an illustration of how the fibers are straightened, parallelized, and compacted into a smooth and uniform yarn.

The purpose of a comb sorter diagram is to provide a visual representation of the combing process and to help explain the various steps involved in preparing the fibers for spinning and weaving. This information can be useful for those who are new to the textile industry, as well as for experienced professionals who are interested in learning more about the combing process.

What is fibre length variation ?

Fiber length variation refers to the differences in the length of individual fibers within a sample of fibers. This variation can affect the performance and quality of the fiber and can impact the final textile product.

In textile manufacturing, fiber length is a critical factor in determining the strength, durability, and appearance of the final product. Longer fibers tend to produce stronger and more uniform yarns, while shorter fibers can result in weaker and less uniform yarns.

Fiber length variation can occur due to a number of factors, including the growing conditions of the fibers, the processing methods used to prepare the fibers for spinning, and the mechanical processes used to form the yarns.

To minimize fiber length variation, manufacturers use various techniques, such as sorting the fibers by length and blending fibers of different lengths, to produce a more uniform yarn.

In summary, fiber length variation is an important factor that affects the quality and performance of fibers and textiles, and it is carefully monitored and managed throughout the textile manufacturing process.
