[0033] A pretreatment agent for waste and old clothes, which is made of the following raw materials and parts by weight: 20 parts of foam liquid, 5 parts of eucalyptus leaf extract, and 2 parts of fragrance leaf extract;

[0034] The foam liquid is processed by compounding fatty alcohol sodium sulfate, cetyl alcohol, Sapindus chinensis extract, co-solvent, thickener and water according to the mass ratio (1:2:5:2:3:100) ;

[0035] The co-solvent is composed of water-soluble fatty alcohol polyoxyethylene ether;

[0036] Described thickener is alginic acid;

[0037] Described foam liquid concentration is 3.0% (Wt);

[0038] Soak waste clothes and trousers fabrics in the waste clothes pretreatment agent prepared above, soak them for 30 minutes, turn them twice, and then centrifugally dry them for 60 seconds to obtain fabrics with a moisture content of 40%, just dry them.

Embodiment 2

[0040] A pretreatment agent for waste and old clothes, which is made of the following raw materials and parts by weight: 30 parts of foam liquid, 8 parts of eucalyptus leaf extract, and 4 parts of fragrance leaf extract;

[0041] The foam liquid is processed by compounding fatty alcohol sodium sulfate, n-decyl alcohol, Sapindus chinensis extract, co-solvent, thickener and water according to the mass ratio (2:1:8:3:5:120) ;

[0042] The co-solvent is composed of water-soluble fatty alcohol polyoxyethylene ether and water-soluble polyether in a mass ratio (2:1);

[0043] Described thickening agent is sodium carboxymethyl cellulose;

[0044] Described foam liquid concentration is 8.0% (Wt);

[0045] Soak waste clothes and trousers fabrics in the waste clothes pretreatment agent prepared above, soak for 50 minutes, turn over 4 times, and then centrifuge and dry for 80 seconds to obtain fabrics with a moisture content of 30%, just dry them.

Embodiment 3

[0047] A pretreatment agent for waste and old clothes, which is made of the following raw materials and parts by weight: 40 parts of foam liquid, 10 parts of eucalyptus leaf extract, and 6 parts of fragrance leaf extract;

[0048] The foam liquid is processed by compounding fatty alcohol sodium sulfate, cetyl alcohol, Sapindus chinensis extract, co-solvent, thickener and water according to the mass ratio (5:2:12:3:5:150) ;

[0049] The co-solvent is composed of water-soluble polyether;

[0050] The thickener is an ionic thickener consisting of a mixture of alginic acid and sodium carboxymethylcellulose in a mass ratio (2:1);

[0051] Described foam liquid concentration is 5.0% (Wt);

[0052] Soak old clothes and pants fabrics containing more than 40% cotton in the above-prepared pretreatment agent, soak for 200 minutes, and then centrifugally dry for 80 seconds to obtain fabrics with a moisture content of 40%, which can be dried.

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...
