Abstract

The invention discloses a waste clothes pretreatment agent. The waste clothes pretreatment agent is prepared from the following raw materials in parts by weight of 20-40 parts of foam liquid, 5-10 parts of eucalyptus leaf extracting solution and 2-6 parts of pistacia weinmannifolia leaf extract. Waste clothes pretreated by using the waste clothes pretreatment agent provided by the invention have relatively high antibacterial activity, allergy prevention and washability, the fiber uniformity is improved, and meanwhile, the waste clothes pretreatment agent has a relatively long-lasting skin care effect and a relatively long-lasting peculiar smell removal effect.

Description

technical field [0001] The invention relates to the field of textile processing, in particular to a pretreatment agent for waste and old clothes. Background technique [0002] According to the survey, my country currently produces nearly 30 million tons of waste textiles annually, most of which are old clothes discarded by residents, becoming a huge "indoor pollutant" and causing great pressure on the environment. Generally speaking, after the clothes are recycled, according to the degree of newness and oldness, all the clothes that are more than 80% to 90% new will be selected for cleaning and disinfection pretreatment before further use. [0003] For waste clothes, the proportion of chemical fiber products is as high as 60% to 70%. There are often problems such as clothes appear old, the recycling rate is low, the sorting utilization rate is not high, and there are peculiar smells. [0004] The traditional recycling technology, after manual sorting, disinfection, cleaning...
