The invention aims to provide an environment-friendly processing technology for improving the easy-to-clean performance of resin finishing, which has scientific and reasonable design, energy conservation and environmental protection, and the product has good easy-to-clean performance and washing resistance and obvious economic benefit.
The environment-friendly processing technology for improving the easy-to-decontaminate performance of resin finishing comprises the following steps:
the pure cotton fabric is subjected to singeing → desizing → bleaching → mercerizing → whitening or dyeing treatment to obtain a semi-finished product;
the pure cotton semi-finished product padding resin and the fluorine-free environment-friendly soil release finishing liquid comprise the following raw materials in mass volume concentration: moisture crosslinked resin: 180-240 g/L, resin catalyst: 90-120 g/L, fiber protective agent: 30-40 g/L, softening agent: 30-40 g/L, fluorine-free soil release auxiliary agent: 40-90 g/L, and the balance of water. The fabric rolling residual rate is 60-70%, and the moisture content of the dried fabric is 7-8%.
The fabric with the moisture content of 7-8% is rolled and sealed, the fabric is stacked in an environment with the temperature of 38-40 ℃ for 20-24 hours to react, the reacted fabric is washed by a solution with the concentration of 2-5 g/L of soda ash, and then fully washed and dried by clear water with the temperature of 50-60 ℃ to obtain the environment-friendly soil release fabric.
The finished fabric is placed on the saddle frame in order.
Preferably, the resin catalyst is RAYCARE LRMC of Ziboruri fine chemical Co., Ltd, and the auxiliary agent is a mixture of organic acid salt, and can provide reaction conditions for resin reaction and reaction of fluorine-free easy-cleaning auxiliary agent.
The dosage of the resin catalyst is preferably 110g/L, and the dosage is not less than 90 g/L. If the amount is less than 90g/L, the organic acid and inorganic salt in the catalyst do not provide acidic and crosslinking reaction conditions for the reaction of the soil release aid, resulting in poor soil release and wash resistance.
Preferably, the fiber protective agent is nonionic polyethylene wax type emulsion, more preferably CAN produced by Hensmei textile dyeing Co., Ltd, and the dosage is preferably 35g/L and is not higher than 40 g/L. If the amount exceeds 40g/L, the increased affinity for contaminants during the reaction tends to be difficult to remove.
Preferably, the softening agent is a nano-grade modified amino silicone oil super softening agent, and further preferably PRIME LA produced by Qingdao Ono chemical company Limited, and the dosage is preferably 35g/L and is not more than 40 g/L.

The dosage of the fluorine-free soil release auxiliary agent is preferably 60g/L, and the dosage is not lower than 40 g/L. If the dosage of the auxiliary agent is less than 40g/L, the fluorine-free soil release auxiliary agent can not cover the fiber surface after reaction, which results in poor soil release performance. The usage amount of the fluorine-free soil release auxiliary agent is limited to 40-90 g/L, so that the reactive anchoring group in the auxiliary agent can react with cellulose molecules.
The concentration of the calcined soda used for washing after the reaction is 2-5 g/L, preferably 3/L, and the using amount is not lower than 2g/L and not higher than 5 g/L. When the dosage is less than 2g/L, unreacted soil release auxiliary agent and moisture-state crosslinking resin cannot be sufficiently washed away; when the content of the sodium carbonate is more than 5g/L, the reacted soil release auxiliary agent and the moisture-state crosslinking resin are easy to be fully decomposed without causing partial shedding, so that the soil release performance and the easy-care performance are influenced.
The fabric with the moisture content of 7-8% is rolled and sealed, so that the fabric can better permeate in the stacking process, and the reaction sufficiency of the fabric is improved.
In the finishing liquid, the fluorine-free soil release auxiliary agent and the moisture cross-linked resin are processed in the same bath, and hydroxyl in the fluorine-free soil release is fully utilized to be combined with cellulose and hydroxyl on the resin through covalent bonds; the processing technology provided by the invention has the advantages of low energy consumption, no need of high-temperature baking, good soil release performance and durability, environmental protection and good economic benefit.
Compared with the prior art, the invention has the following beneficial effects:
(1) the resin and the soil release finishing liquid are reasonably prepared, have good permeability to cellulose fabric, can enable the soil release auxiliary agent to fully perform crosslinking reaction at 38-40 ℃, achieve good soil release effect, and are bonded with hydroxyl on the fiber through covalent bonds so as to be fixed on the fiber;
(2) according to the invention, the soil release reaction and the resin reaction are carried out simultaneously, and the resin and the soil release auxiliary agent are uniformly distributed among fiber molecules to form a net structure, so that the phenomenon that the conventional high-temperature baking reaction is easy to agglomerate and gather on the fiber surface, which causes poor soil release effect is avoided; the washing fastness of the detergent is greatly improved by a net structure formed by the reaction of the easy-to-clean auxiliary agent, and the effect of 50 times of washing can be realized;
the easy-care soil release fabric produced by the technology has the advantages that the easy-care performance is not affected, the fabric reaches more than 3.5 grade under the AATCC 124 method, the soil release performance reaches 4 grade under the AATCC 130 method, the soil release performance can still reach 3 grade after 50 times of household washing, and the comprehensive performance is very excellent;
(3) the process disclosed by the invention has the advantages that the soil is easily removed at normal temperature (38-40 ℃) and can react with cellulose, the energy consumption in the production process is greatly reduced, the wearability of the fabric is greatly improved, the resource waste is reduced, the process is more environment-friendly, the economic benefit is good, and the popularization prospect is good.
