纺织厂装备了各具噪声特性的机器,将织机的铸铁部件用塑料代替可获得显著的减噪量。但其代价较高,即使减少10～15dB,仍不足以消除对听觉的危害,故尚需对机器重新设计。本文涉及产生大部分噪声的纺织工艺,如梳理、清棉、混和、并料、纺纱等。 Textile mills are equipped with machines that have various noise characteristics and can obtain significant noise reduction by replacing the plastic part of the loom with cast iron. However, its high cost, even if reduced by 10 ~ 15dB, is still not enough to eliminate the hazards of hearing, it still need to redesign the machine. This article deals with the textile processes that generate most of the noise, such as carding, cleaning, mixing, dosing, spinning and so on.
