Composite of dry cleaning solvent

Abstract

The invention provides a composite of dry cleaning solvent. The composite consists of a cleaning solvent, and synergistic components, wherein the synergistic components comprise water and a water modifier. The composite of dry cleaning solvent can effectively clean hydrophilic and hydrophobic blots without damaging clothes and accessories of the clothes; after being cleaned by the composite of dry cleaning solvent, the clothes are loose and soft; and the composite of dry cleaning solvent is safe to the environment as well as the human bodies, and is an ideal system of dry cleaning solvent.

Description

technical field [0001] The invention relates to the field of washing products, in particular to a dry cleaning solvent composition. Background technique [0002] The two most used dry cleaning solvents worldwide are perchlorethylene (PERC) and petroleum. Perchlorethylene has high cleaning power, is inexpensive, non-flammable, and has good chemical stability. However, PERC has two major shortcomings, which make it not an ideal dry cleaning solvent: (1), the problems it brings to personal safety and environmental protection: after it enters the human respiratory tract, it may cause damage to the liver, kidneys, skin and nerves, etc. damage to organ systems; at the same time, it is harmful to the environment because it cannot be degraded naturally and can accumulate over time leading to major industrial hazardous waste disposal problems. (2) The "dissolution" ability of PERC is sometimes too high to damage the accessories on clothing such as beads, sequins, metal and buttons....

AI Technical Summary

Problems solved by technology

However, PERC has two major shortcomings, which make it not an ideal dry cleaning solvent: (1), the problems it brings to personal safety and environmental protection: after it enters the human respiratory tract, it may cause damage to the liver, kidneys, skin and nerves, etc. Damage to organ systems; at the same time, it is harmful to the environment because it cannot be degraded naturally and can accumulate over time leading to major industrial hazardous waste disposal problems

(2) PERC's "dissolution" ability is sometimes too high to damage clothing accessories such as beads, sequins, metal and buttons, etc.

It is also not as effective as tetrachlorethylene in cleaning some granular stains, because the particle suspension ability of D5 is less

Although some cleaning additives for dry cleaning can improve the cleaning effect of D5 on hydrophilic stains and particulate stains, the improvement effect is limited, and pretreatment before dry cleaning and post-treatment after dry cleaning are often unavoidable, resulting in increased labor and cost
