摘要
水刺法是一种非织造布标准缠结加固工艺。虽然它在生产速度及产品特殊性能(触感、柔软度等)的加工方面有诸多优点,但其缺点是高能耗。水刺非织造布在缠结工序的能耗通常为1.2～2.5k·Wh/kg。尽管纤维原料仍在产品总成本中占主导地位,但在产能2 000kg/h、年产量150～250万欧元的水刺非织造布生产线中,能耗费用占其他总费用(能源费、折旧费、贷款利率、维护费等)的40%～50%。因此,降低能耗费用可使水刺非织造布的生产成本大幅降低。
Hydroetanglement is one of the standard entanglement processes for nonwovens. Despite its undeniable advantages in production speed or related to special product properties （to u ch , softness% etc.）, there is one significant downside： its huge energy consumption. In to ta l, the energy consumption for hydroentangled nonwovens is typically in the range of 1. 2-2. 5 k · Wh/kg only for the entanglement part of the production line. While fiber costs still dominate the total costs of the product% the energy costs of hydroentanglement cause 4 0 %？50% of all other costs of such a production line （energy,depreciation,loan costs,maintenance etc.） and add up t o ,depending on product, 1. 5-2. 5 million/year for a nonwovens line with a 2 000 kg/h production. Thus a reduction of these energy costs leads to a significant reduction of the production costs of hydroentangled nonwovens.
