Problems solved by technology

However, it has been proved that the complexing ability of citric acid is very low
Widely used DTPA, IDA, NTA and other substances are not easy to degrade. Phosphorus-containing substances will lead to eutrophication of water bodies and cause environmental pollution. It is believed that metal ions are activated from the sediments at the bottom of the river and underground, resulting in Increased ion concentration

Abstract

The invention discloses a long-acting whitening detergent with an efficient chelating capability and a preparing method thereof. The long-acting whitening detergent is prepared from, by weight, 8-10 parts of soap powder, 8-12 parts of alkali, 12-20 parts of tetrasodium glutamate diacetate, 15-20 parts of methyl glycine diacetic acid, 8-15 parts of sodium iminodisuccinate, 15-20 parts of hydroxyethylidene diphosphonic acid, 6-10 parts of ethylene diamine tetraacetic acid tetrasodium and 7-12 parts of a maleic acid-acrylic copolymer. The long-acting whitening detergent is wide in source of raw materials and simple in preparing technology; by cooperatively using different raw materials, the prepared finished product has a strong chelating capability and a wide using prospect.

Description

technical field [0001] The invention relates to a cleaning aid, in particular to a detergent which chelates metal ion dirt and can significantly improve the whiteness of fabrics. Background technique [0002] Linen is a general term for clothes, sheets, quilt covers, bath towels, etc. of different textures in the hotel laundry room. At present, the cleaning agents used in the cleaning of linen are gradually specialized, and different washing processes and cleaning agents are used according to different stains on the linen. In practice, the linen after repeated washing is prone to graying, yellowing, or even hardening, which shortens the service life of the linen and greatly increases the cost. The reason for the above phenomenon of linen is that the metal ions contained in water, equipment and cleaning agents are attached to the linen fibers, and these metal ions are mainly calcium, magnesium and iron ions. [0003] At present, most manufacturers of cleaning products at ho...
