Carding method and carding machine for cashmere fibers

Abstract

The invention discloses a cashmere fiber carding method and carding machine.The carding method comprises the procedures such as hair tuft pre-treatment, and the pre-treatment procedure includes the steps of drafting fed hair tufts, subjecting the drafted hair tufts to long-distance garnetting, primarily combing the garnetted hair tufts to form hair tuft fiber bundles, and subjecting the hair tuft fiber bundles to opening, combing and finishing and cleaning by opening step by step.The carding machine comprises a pre-treatment mechanism, and the pre-treatment mechanism comprises a drafting mechanism, a primary combing mechanism, and an opening cleaning mechanism sequentially from front to rear.Before the hair tufts are opened, the hair tufts in tangled form are gradually drafted into loose form and gradually combed from the loose form to the hair tuft fiber bundle form at the premise that long fiber in cashmere in the hair tufts is protected from being broken, damage to the cashmere fiber can be greatly reduced during opening and carding, and the quality of carded cashmere fiber can be greatly improved.

Description

technical field [0001] The invention relates to a carding method and carding equipment in the textile field, in particular to a cashmere fiber carding method and a carding machine. Background technique [0002] At present, in the carding process of the wool textile industry, especially the carding methods for washed cashmere raw materials mainly include: repeated carding of "feeding board---licker-in-cover board", roller Opening--repeated combing of "feeding board---licker-in-cover board", double cillin opening--"roller air suspension" carding, roller opening---- Repeated "feeding board --- licker-in roller" combined carding form. [0003] Such as figure 1 As shown, the way of feeding, carding and opening of traditional carding is that the fleece board 0-1 and the grooved feed roller 0-2 are tightly held and the fibers are fed, and the metal on the licker-in roller 0-3 The fibers fed by the sawtooth card clothing at the point where the card clothing distance is the smalle...

AI Technical Summary

Problems solved by technology

This method has two effects on the fiber bundle at a very small distance, that is, the instantaneous puncture and cutting at the point of the stalemate needle point, and the large tearing force caused by the forceful hooking at a short distance. Fiber damage is very important, and it is easy to lose hair pieces under the carding point

[0005] Although the existing technology can realize the carding process, there are problems that the long fibers that need to be protected are greatly damaged, and the quality and extraction rate management of single-machine sets in production is difficult.
