Description
Technical Field
The invention relates to an environment-friendly processing technology for improving soil release performance of resin finishing, and belongs to the technical field of textile finishing.
Background
At present, people pay more attention to environmental protection consciousness, and pursuit of environmental protection clothes is also higher. However, the existing easy-to-clean auxiliary products mainly contain fluorine and do not meet the green development requirement. Fluorine-free adjuvant products have been developed, but have problems in the application process. For example, the technical bottlenecks of poor soil release performance, poor washing resistance and high energy consumption in the processing process are still not improved.
The prior soil release technology has related technical reports, but the invention technology still has certain technical problems.
In the finishing process (CN 112921662A) of the pure cotton non-ironing easy-to-decontaminating fabric of Zheng Zhenlong and the like, the adopted easy-to-decontaminating auxiliary agent is a C6 auxiliary agent, the easy-to-decontaminating auxiliary agent and the post-baking auxiliary agent are processed in one bath, and the easy-to-decontaminating auxiliary agent is subjected to crosslinking reaction by utilizing the high-temperature baking condition of the post-baking finishing. The technology has high energy consumption in the production process, and the color change of the fabric is large after high-temperature reaction, the whiteness is reduced greatly, the technology is not suitable for white fabric, and the fabric is only 3.5-grade before easy decontamination and washing and can only reach the durability of 10 times of washing.
Zhong Weihao, the technology is that fluorine-free easy-to-decontaminate auxiliary agent TF-9901 is added into formaldehyde-free easy-to-iron finishing bath, and the reaction is carried out by using the easy-to-iron high temperature baking condition to achieve good easy-to-decontaminate effect, and the fluorine-free easy-to-decontaminate auxiliary agent is simply filled into the fiber and cannot form firm chemical bonds with fiber molecules, so that the washing resistance is poor. The decontamination performance of the fabric prepared by the patent is reduced from 4 levels before washing to 3 levels after 5 times of washing, the energy consumption in the production process is high, the decontamination performance and the washing fastness are poor, and the requirement of people on durable fabric can not be met.
Tao Xiaohua A process for preparing the anti-ultraviolet and soil-release finishing agent for cotton fabric (CN 111074612A) features that the C6 soil-release finishing agent and ultraviolet-proof agent are processed in one bath, and the high-temp baking condition is used to make the reaction to obtain soil-release effect. The technology of the invention has high energy consumption and poor washing resistance.
In summary, the existing soil release finishing technology does not realize the effects of environmental protection, low energy consumption and durability, and the soil release effect does not reach the expected result.
Disclosure of Invention
The invention aims to provide an environment-friendly processing technology for improving the soil release performance of resin finishing, which has scientific and reasonable design, energy conservation and environment protection, and the product has good soil release performance and washing resistance and obvious economic benefit.
The invention relates to an environment-friendly processing technology for improving the soil release performance of resin finishing, which 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;
pure cotton semi-product padding resin and fluorine-free environment-friendly soil release finishing liquid, wherein the finishing liquid comprises the following raw materials in mass volume concentration: moisture-state crosslinking resin: 180-240 g/L, resin catalyst: 90-120 g/L, fiber protective agent: 30-40 g/L, softening agent: 30-40 g/L of fluorine-free easy-to-clean auxiliary agent: 40-90 g/L, and the balance of water. The rolling residual rate of the fabric is 60-70%, and the moisture content of the dried fabric is 7-8%.
Rolling and sealing the fabric with the moisture content of 7-8%, stacking for 20-24 h in the environment of 38-40 ℃ for reaction, washing the fabric after the reaction by a solution with the sodium carbonate concentration of 2-5 g/L, and fully washing and drying the fabric by clear water with the temperature of 50-60 ℃ to obtain the environment-friendly easy-to-decontaminate fabric.
The finished fabric is placed on the saddle in order.
Preferably, the resin catalyst is RAYCARE LRMC of the fine chemical engineering Co.Ltd.of the catalpol Lu Rui, and the auxiliary agent is a mixture of organic acid grade salts, so that reaction conditions can be provided for the resin reaction and the reaction of the fluorine-free easy-to-clean auxiliary agent.
The resin catalyst is preferably used in an amount of 110g/L and in an amount of not less than 90g/L. If the amount is less than 90g/L, the organic acid and inorganic salt in the catalyst cannot 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 protecting agent is a nonionic polyethylene wax emulsion, more preferably CAN produced by Henschel textile dyeing Co., ltd, preferably in an amount of 35g/L and in an amount of not more than 40g/L. If the amount exceeds 40g/L, the contamination resistance during the reaction is easily enhanced and difficult to remove.
Preferably, the softener is a nanoscale modified amino silicone oil super softener, more preferably PRIME LA manufactured by Qingdao European North chemical Co., ltd, and the dosage is preferably 35g/L and no more than 40g/L. If the amount exceeds 40g/L, the increased hydrophilic groups in the softener affect the detergency of the soil release aid in the washing process.
Preferably, the fluorine-free easy-to-remove detergent additive is TF-9901B of Zhi Lian Co., ltd, and the main component of the additive is hydrocarbon and does not contain fluorine; the appearance is light white liquid, the pH value of the stock solution is 6.5-7.5, the product belongs to cationic/nonionic performance, and is suitable for processing resin and easy-to-decontaminate in one bath.
The dosage of the fluorine-free easy-to-clean auxiliary agent is preferably 60g/L, and the dosage is not less than 40g/L. If the dosage of the auxiliary agent is less than 40g/L, the fluorine-free easy-to-decontaminate auxiliary agent can not cover the surface of the fiber after reaction, and the easy-to-decontaminate performance is poor. The dosage of the fluorine-free easy-to-clean 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 sodium carbonate used for washing after the reaction is 2-5 g/L, preferably 3/L, and the dosage is not less than 2g/L and not more than 5g/L. When the amount is less than 2g/L, unreacted detergency builder and the wet crosslinked resin cannot be sufficiently washed off; when the sodium carbonate is higher than 5g/L, the reacted soil release auxiliary agent and the moisture crosslinking resin are easy to fully decompose without causing partial falling off, thereby influencing the soil release performance and the non-ironing performance.
The fabric with the moisture content of 7-8% is coiled 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 easy-to-decontaminate auxiliary agent and the wet cross-linked resin are processed in the same bath, and hydroxyl groups in fluorine-free easy-to-decontaminate are fully utilized to generate covalent bond combination with hydroxyl groups on cellulose and resin; the processing technology provided by the invention has the advantages of low energy consumption, good soil release performance and durability, environmental protection and good economic benefit, and can be obtained without high-temperature baking.
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 fabrics, can enable the soil release auxiliary agent to fully carry out crosslinking reaction in the environment of 38-40 ℃ and achieve good soil release effect, and are covalently bonded with hydroxyl groups on fibers to be fixed on the fibers;
(2) 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 surface of the fiber and the soil release effect is poor is avoided; the reticular structure formed by the reaction of the easy-to-clean auxiliary agent greatly improves the washing resistance and can realize the effect of 50 times of washing;
the non-ironing easy-to-decontaminate fabric produced by the technology has no influence on non-ironing property, reaches over 3.5 level under the AATCC 124 method, has easy-to-decontaminate performance reaching 4 level under the AATCC 130 method, can still reach 3 level after 50 times of family washing, and has excellent comprehensive performance;
(3) The process disclosed by the invention has the advantages that the soil release can be carried out with cellulose at normal temperature (38-40 ℃), the energy consumption in the production process is greatly reduced, the wearability of the fabric is greatly improved, the resource waste is reduced, the environment is more friendly, the economic benefit is good, and the popularization prospect is good.
