Preparation method of environmentally-friendly pure cotton book jacket with waterproof and oilproof functions

Abstract

The invention discloses a preparation method of an environmentally-friendly pure cotton book jacket with waterproof and oilproof functions. The method comprises the steps that a pure cotton fabric woven by a weaving machine is adopted, fabric surface softener is removed, and the cloth cover is leveled; a six fluorocarbon waterproof and oilproof process agent and a waterproof cross-linking agent for cotton are added in pure water, and finishing liquor containing 40-60 g / L of six fluorocarbon waterproof and oilproof process agent and 8-10 g / L of waterproof cross-linking agent for cotton is prepared; in a normal temperature state, the finishing liquor is adopted for soaking and dipping, wherein the soaking time is 60 s, and the liquid rate of the fabric obtained after dipping is 75%-85%; thefabric obtained after dipping is dried and set to 60 s under the environment of 160 DEG C; the fabric is cut and sewn, and a needed book jacket style is formed. Accordingly, after the book jacket is treated through the finishing liquor, the waterproof property reaches a score of 100, the oilproof property reaches the level 6, the natural characteristics of the pure cotton book jacket are kept, andmeanwhile the book jacket has the excellent waterproof and oilproof functions and does not contain non-environmentally-friendly components such as PFOS, PFOA and APEO.

Description

Technical field: [0001] The invention belongs to the technical field of preparation of pure cotton book jackets, in particular to a preparation method of an environment-friendly pure cotton book jacket with waterproof and oil-proof functions. Background technique: [0002] The function of the book jacket is to protect the internal books in real time, preventing water or oil from infiltrating the book jacket from causing damage to the books. Book jackets will inevitably encounter liquid (including water and oil) pouring, splashing or dipping and other pollution phenomena during use. If the book jacket does not have waterproof and oil-proof functions, pollutants will infiltrate the internal books through the book jacket , which in turn affects the use and collection of books. At present, plastic book jackets are more common. Although the plastic material has certain waterproof and oil-proof functions, it is difficult to degrade itself. Even improper material selection and dye...

Problems solved by technology

Book jackets will inevitably encounter liquid (including water and oil) pouring, splashing or dipping and other pollution phenomena during use. If the book jacket does not have waterproof and oil-proof functions, pollutants will infiltrate the internal books through the book jacket , which in turn affects the use and collection of books

At present, plastic book jackets are more common. Although the plastic material has certain waterproof and oil-proof functions, it is difficult to degrade itself. Even improper material selection and dyeing treatment will make plastic book jackets contain toxic ingredients and endanger the health of users.

In recent years, manufacturers have developed fabric book jackets finished with waterproof and oil-proof functions, but their waterproof and oil-proof finishing agents usually contain perfluorooctanoic acid ammonium (PFOA), perfluorooctane sulfonate (PFOS) and alkylphenols. Polyoxyethylene ether (APEO) and other substances are extremely difficult to degrade, and their toxicity and environmental hazards are clear. Long-term use will cause harm to human health and the ecological environment
