Technical Field

The invention belongs to the technical field of functional textiles, relates to performance repair of functional fabrics, and particularly relates to a three-proofing soil-release tool and a fabric performance repair method. The method realizes infiltration repair at higher temperature, does not influence the color light and the color fastness of the fabric, and completely avoids economic loss caused by re-throwing production.

Background

Along with the improvement of the living standard of people and the acceleration of the rhythm of life, the functional requirements of consumers on textile fabrics are higher and higher, and under the background environment, the three-proofing soil-release tooling fabric is rapidly and widely used with the visual functional effect and the extremely simple nursing mode. The three-proofing fabric is prepared by specially finishing the fabric by using the organic fluorine finishing agent, and has the functions of oil resistance, water resistance and easy decontamination.

When the fabric is in a dry state, the three-proofing fabric has good protection effect on water-based and oil-based stains; when the fabric is in a wet state, the soil-release fabric has good protective effect on water-based and oil-based stains; the three-proofing easy-decontamination composite finished fabric has good protection effect on water-based and oily stains no matter in a dry state or a wet state. However, when the finished fabric is subjected to quality inspection, performance indexes of the finished fabric are not qualified, for example, the initial water-proof, oil-proof and soil release performance is relatively low, and the water-proof, oil-proof and soil release performance is seriously reduced after water washing according to AATCC-135 fabric household washing size change, for example: after 10 times of water washing, the waterproof performance of the fabric required by customers is more than or equal to 80 minutes, and actually after 10 times of water washing, the waterproof performance of the fabric is 70 minutes. When the index is unqualified, the industry adopts re-blank feeding for dyeing finishing processing, and the three-proofing and soil-release tooling fabric cannot be bleached and dyed again due to extremely strong water and oil repellency. Therefore, no good method for restoring the performance of the fabric exists at present.

Disclosure of Invention

The invention aims to provide a method for repairing the performance of a three-proofing soil-release tooling fabric, which is used for repairing the performance of an unqualified fabric.

The technical scheme adopted by the invention for realizing the purpose is as follows:

a method for repairing performances of a polyester-cotton three-proofing soil-release tooling fabric comprises the following steps of:

A. preparation of an auxiliary agent solution: mixing an auxiliary agent and water according to the mass ratio of 1 (2-10) to obtain an auxiliary agent solution, and uniformly dividing the auxiliary agent solution into 3 parts, namely an auxiliary agent I, an auxiliary agent II and an auxiliary agent III; the auxiliary agent comprises 8-10 parts by weight of isopropanol, 20-100 parts by weight of organic fluorine finishing agent, 20-60 parts by weight of synergist and 40-100 parts by weight of modified fatty acid ester;

B. repairing treatment: placing the three-proofing and soil-release tooling fabric to be repaired in a roller, adding the auxiliary agent I at normal temperature, treating for 10min, then adding the auxiliary agent II, treating for 10min, then adding the auxiliary agent III, treating for 10min, then heating to 40 ℃, and carrying out heat preservation treatment for 30 min;

C. and (3) post-treatment: and C, after padding the to-be-repaired three-prevention soil-release tooling fabric processed in the step B, tentering, drying and baking the to-be-repaired three-prevention soil-release tooling fabric to finish the performance repair of the three-prevention soil-release tooling fabric. And (4) during padding, the rest of the auxiliary agent solution in the step (B) is selected and used in the rolling groove.

The organic fluorine finishing agent is one or two combinations of C6 structure, TG-5521 and TG-9011, and adopts two combinations of TG-5521 and TG-9011 to control TG-5The mass ratio of 521 to TG-9011 is 1: 2. Organofluorine finish its ionicity: weak cation, pH 4-6, specific gravity: 1g/m²Appearance: a light yellow liquid; it is suitable for weaving and knitting cotton, hemp, wool, silk, chemical fiber and blended fabric. Can endow the fabric with high-end performance such as water resistance, oil resistance, SR and the like, and has good washing fastness and processing stability. The trade name of TG-5521 and TG-9011 is three-proofing agent TG-5521 and stain-removing agent TG-9011 from Japan Dajin Co.

The synergist is a bridging agent DM-3911 (Guangdong Germany fine chemical company) with an isocyanate structure.

The modified fatty acid ester is a modified fatty acid ester softening agent DT-4040.

In step B, the temperature is raised to 40 ℃ at a heating rate of 1 ℃/min.

And C, padding until the liquid carrying rate is 60-65%.

In the step C, the drying temperature is 100-.

The invention has the beneficial effects that:

the three-proofing agent and the easy detergent are oil-in-water high molecular aqueous solution formed by emulsifying through an emulsifier, when the temperature of a use environment is too high, the molecular kinetic energy is increased, the Van der Waals force among molecules is reduced, water and oil are separated, the three-proofing agent and the easy detergent are layered and demulsified, and the three-proofing agent and the easy detergent cannot be normally used. Therefore, the three-proofing soil release finishing in traditional cognition and actual production is selected from low-temperature padding operation, and the lower the temperature is, the better the temperature is, and the temperature is generally not more than 30 ℃.

The infiltration repairing method adopted in the scheme has the following advantages: (1) isopropanol is adopted in the formula to improve the permeability of the repair finishing liquid on the fabric and the use stability of the repair finishing liquid, so that good basic conditions are provided for realizing the infiltration repair of the fabric at higher temperature; (2) the infiltration repairing process adopts a gradual heating mode to 40-45 ℃, so that the finishing liquid can uniformly permeate on the fabric, the stability of the finishing liquid is ensured, the abnormal problems of emulsion breaking and the like are avoided, and the safety operability is high; (3) in terms of equipment type selection, the performance of the three-proofing and soil-release tooling fabric can be repaired by using the normal-temperature normal-pressure jig dyeing machine and the normal-temperature normal-pressure airflow dyeing machine, investment or replacement of new equipment is not needed, and the three-proofing and soil-release tooling fabric has strong applicability; (4) the repairing method has the characteristics of low temperature and short time, cannot generate adverse influence on the color light and color fastness of dyed fabrics, can completely meet the requirements of customers in terms of functional effect after repairing, avoids economic loss caused by previous blank throwing production, and has strong timeliness.
