Abstract

The invention discloses a water softener for printing and dyeing. The water softener comprises the following components according to parts by weight: 20-30 parts of sodium carbonate, 5-8 parts of trisodium phosphate, 3-5 parts of sodium hydroxide, 10-20 parts of sodium hexametaphosphate, and 0.3-0.5 part of sodium ethylene diamine tetraacetic acid. Compared with the prior art, the water softener can effectively lower the concentration of calcium ion and magnesium ion in water, and can be combined with copper ion and iron ion so as to form stable complex, thus having very good softening effect.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, and more particularly relates to a water softener for printing and dyeing. Background technique [0002] Printing and dyeing plants consume a lot of water in dyeing and finishing, from desizing, scouring, bleaching, mercerizing to dyeing, printing, finishing and boiler steam supply. [0003] There are two main sources of water for textile dyeing and finishing, one is surface water, such as river, river, lake water, and the other is groundwater, such as deep well water, spring water, etc. The source of surface water is sufficient, but the water quality is often affected by flow, season and environment, and generally contains more suspended solids, such as sediment, dust, microorganisms and a small amount of organic matter. Groundwater quality is stable and clear, but due to geological influences, it often contains more minerals. The tap water usually used is the s...
