Carding process

Carding Process of making fibers parallel by using rollers covered with needles. 

The jute or kenaf fiber of commerce refers to the sheath extracted from the plant stems, whereas a single fiber is a cell bundle that forms one of the links of the mesh. Staple length, as applied to cotton and wool fibers, has no counterpart in the base fibers, and, as a preliminary to spinning, it is necessary to break up the sheaths by a carding process. The fragments so produced are the equivalent of the staple fibers of the cotton and wool industries.

Card conversion efficiency n. The efficiency of the carding process, expressed as a percentage obtained from ratio of sliver output to staple input. 

Picker n. (1) A machine that opens staple fiber and forms a lap for the carding process used in the production of spun yarns. (2) It is the part of the picking mechanism of the loom that actually strikes the shuttle.

It was possible to knit, from the yam, a small piece of fabric on a hand-driven circular knitmachine. However, itmust be borne in mind that (i) the fabric contains many clumps of entangled fibers giving it a poor appearance and (ii) this is not yet an efficient process with at least 50% of the input material removed as waste by the carding process. 

Dry laid media manufacturing methods are based on traditional opening and carding processes used in the textile industry the media are composed of short fibres. Multiple layers of the open fibres are laid mechanically to form... 

The characteristics of the fibrous web are a key determinant of the physical properties of the final product. Fibre length determines the choice of methods for forming webs. Initially, the methods for the formation of webs from staple-length fibres were based on the textile carding process, whereas web formation from short fibres was based on a wet laid process similar to papermaking. These technologies are stiU in use, but... 

Roller cards process coarse polyester fibers with the crosslap technique into cross-laid webs with differently constructed layers.
