The test of the wire brush on the combing machine

　The quality of the brush used in the combing machine is of high quality, which is very important for the effective elimination of the mixed and short plush, the control of the cotton fluctuation and the improvement of the quality of the comb. Since the 1950s, China has been using the domestic combing machine, and the use of the brush has been improved and improved in practice. First yellow brown hair brush, because of its thickness uneven, easy to break, elastic low, clear cotton knot impurity effect difference, have been eliminated. Is now in general use cotton mills around Mexico import white hair brush made of brown, it has good elasticity, fineness of moderate, remove nep material effect is good wait for an advantage, but with longer duration of use, the cylinder after the first few rows of needle can"t effectively remove applique, effect not exclude knot ability and carding effect.

　The uniformity of steel wire brush is the best, because its steel wire is uniform and the puncture performance is good, so it can effectively clear the inlaid flowers in the tin forest, so that it can fully play the combing effect. Steel wire brush due to the special material, not easy to wear and use the 27 months later, brush the outer diameter of basically remain unchanged, the brush into the cylinder depth stable installation process, to ensure its long-term effectively remove cylinder carding down linter and nep impurities. Therefore, the wire brush is applied to the combing machine, and compared with the use of white brown hair brush, the following three conclusions are drawn:
　(1) the use of steel wire brush flocking needle cylinder has been completely solved the cylinder "applique" the production problem, both can solve the problem of production quality, and reduce the labor intensity of the female workers pick cylinder (work).
　(2) on the removal of the cotton knot, the wire brush also has certain advantages. The second average of the wool brush removal efficiency is 44.68%, while the second average of the white palm brush is 30.62%. On the removal of impurities, the wire brush is slightly better than the white brown brush, and the secondary average of the impurity rate is 66.3%. The second average of white brown was 58.97%.
　(3) in the case of the rate of the combing down cotton to the internal control index, the nodhole difference of the wire brush was better than that of the white palm brush, and the quadratic average was 2.48%, while the second average of the white palm brush was 3.92%.
　To sum up, the wire brush can effectively remove the embedded flowers in the tin forest, and it has high use and promotion value on the comb machine.
