Embodiment Construction
[0014] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.
[0015] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.
[0016] like figure 1 Shown, a kind of finishing method of environment-friendly pure cotton fabric with three anti-functions, its steps are:
[0017] (1) Fabric preparation: use plain, twill, or jacquard pure cotton fabrics woven by weaving, the shrinkage rate is less than 2%, dyed or undyed, the fabric surface softener is removed, and the cloth surface is smoothed;
[0018] (2) Preparation of finishing liquid: Add hexacarbon fluorochemical waterproof and oil-repellent proces...

The invention discloses a method for finishing environment-friendly pure cotton textile fabrics with waterproof, oil-proof and antifouling functions. The method includes removing textile fabric surface softening agents from woven pure cotton textile fabrics and leveling cloth surfaces; adding hexa-fluorocarbon waterproof and oil-proof finishing agents and cotton waterproof cross-linking agents into purified water to prepare finishing liquor; impregnating and padding the pure cotton textile fabrics once by the aid of the finishing liquid in normal-temperature states; carrying out drying and type approval on padded fabrics in environments at the temperatures of 170 DEG C for 80-90 s; cutting and sewing the fabrics to obtain required book cloth styles. The content of the hexa-fluorocarbon waterproof and oil-proof finishing agents in the prepared finishing liquor is 20-35 g / L, and the content of the cotton waterproof cross-linking agents in the prepared finishing liquor is 6-7.5 g / L. The pure cotton textile fabrics are impregnated by the aid of the finishing liquor for the impregnation time of 80-90 s, and the pickup of the padded textile fabrics is 75%-85%. The method has the advantages that the waterproof properties of book cloth treated by finishing agents can reach 100 grades, the oil-proof properties of the book cloth can reach the 6 level, the antifouling properties of the book cloth can reach the 6 level, and the book cloth does not contain components such as PFOS (perfluorooctane sulfonates), PFOA (perfluorooctanoic acid) and APEO (alkylphenol ethoxylates) which are notenvironmentally friendly.
Description
Technical field: [0001] The invention belongs to the technical field of preparation of pure cotton fabrics, and in particular relates to a finishing method of environment-friendly pure cotton fabrics with three-proof functions. Background technique: [0002] At present, the three-proof finishing agents used for fabrics with three-proof functions usually contain substances such as perfluorooctanoic acid ammonium (PFOA), perfluorooctane sulfonate (PFOS) and alkylphenol polyoxyethylene ether (APEO). It is difficult to degrade, and its toxicity and environmental hazards are clear. Long-term use will cause harm to human health and the ecological environment; , Soft and rustic style greatly reduced. Therefore, the environmental friendliness of the pure cotton fabrics finished by the above-mentioned finishing agents and the credibility and degree of cotton products are all greatly negatively affected. [0003] The information disclosed in this Background section is only for enhan...
