Embodiment 1

[0027] The invention discloses a formula of modified green twill core cloth, including modified green polyester, low melting point cotton, three-dimensional vacuum cotton and polyester filament, modified green polyester, low melting point cotton, three-dimensional vacuum cotton and polyester filament The mass fractions are: low melting point cotton 8-22%, modified green polyester 42-58%, three-dimensional vacuum cotton 9-11%; polyester filament 20-27%.

[0028] Wherein, the preparation steps of modified green polyester are as follows:

[0029] S1. Polyester recycled materials are soaked in hydrogen peroxide with a concentration of 10-25% after collection, and the soaking time is 5-10 minutes; the surface oxidized polyester recycled materials are placed in a vacuum drum drying equipment for drying, and the drying time is 8-10 hours;

[0030] S2. Take 100g surface oxidized recycled polyester material, add 5-8g chitosan and 1-5g glass fiber to polymerize and increase viscosity, ...

Abstract

The invention relates to the field of non-woven fabric production, and discloses a formula and a preparation method of a modified green twill core cloth. Through the double improvement of the formula and the process, the recycled polyester material is treated by first oxidation and then cross-linking polymerization, which can effectively The mixing of modified chitosan with glass fiber and polyester reduces the addition of additives and realizes the toughness modification of green polyester; the rationally designed preparation method of Lixin cloth changes the original preparation formula of Lixin cloth and technology, in order to improve the application field of Lixin cloth, the reinforcement and toughness modification was carried out, starting from the recycled polyester as the raw material for the preparation of green polyester, modified with low-cost chitosan and less than 5% glass fiber, and achieved a reduction The cost of modification is reduced, and the mechanical properties of the product are significantly improved.

Description

technical field [0001] The invention relates to the field of non-woven fabric production, in particular to a formula and a preparation method of a modified green twill core cloth. Background technique [0002] According to statistics, chemical fibers accounted for 68.9% of waste textiles produced in my country in 2013, and more than 90% of them were produced from petroleum. If they can be recycled and reused, the consumption of petroleum can be greatly reduced. The widely concerned chemical recycling method can melt or dissolve waste synthetic fibers to obtain polymer materials, which can be further degraded into monomers, repolymerized and spun to make high-quality recycled fiber products. However, depending on the specific components, the recycling methods and recycling values ​​are different. For example, waste polypropylene can be made into recycled polypropylene yarn through physical recycling, which can be used as a secondary reinforcement material for concrete; pure s...
