Problems solved by technology

In recent years, more and more products such as mattresses and cushions are made of brown silk. Although it has strong applicability and good air permeability, its toughness is not ideal. After a long time, brown silk is easy to break after dehydration, and brown cushions are easy to partially collapse.

Embodiment 1

[0025] Embodiment 1 improves the method of brown fiber toughness:

[0026] (1) Once boiled off: 200g water, 80g brown silk, 40g ethyl acetate, 40g wormwood, 7g benzoic acid, 20g locust beans, 2g sodium hydroxide were added in the first processing container by weight to boil off, After obtaining the boiled off brown silk, the boiled off time is 40min, and the boiled off temperature is 90°C.

[0027] (2) Brown silk rubbing treatment: the brown silk obtained by boiling off once is moistened with glutinous rice water, rubbed, and dried in the air to obtain dried brown silk.

[0028] (3) Secondary decoction: put 100g of kerosene, 80g of ethyl acetate, 60g of vegetable oil, and 50g of polyvinyl acetate into the second processing container by weight, raise the temperature of the second processing container and its contents to 60°C, Throw in the processed brown silk of step 2, and obtain the brown silk after being boiled off for the second time after being kept warm for 2 hours.

[...

Embodiment 2

[0031] (6) Post-treatment: Drain the water in the fourth processing container, rinse and rinse the brown silk with 60°C water for 3-5min, then rinse with 15°C water for 10min, drain and air-dry naturally to obtain of brown silk. Embodiment 2 improves the method of brown fiber toughness:

[0032] (1) One time decoction: add 250g water, 120g brown silk, 50g ethyl acetate, 50g wormwood, 10g benzoic acid, 25g locust beans, 4g sodium hydroxide by weight in the first processing container and decoct, After obtaining the boiled off brown silk, the boiled off time is 50min, and the boiled off temperature is 92°C.

[0033] (2) Brown silk rubbing treatment: the brown silk obtained by boiling off once is moistened with glutinous rice water, rubbed, and dried in the air to obtain dried brown silk.

[0034] (3) Secondary decoction: put 125g of kerosene, 100g of ethyl acetate, 130g of vegetable oil, and 70g of polyvinyl acetate into the second processing container by weight, raise the temp...

Embodiment 3

[0037] (6) Post-treatment: Drain the water in the fourth processing container, rinse and rinse the brown silk with 63°C water for 4min, then rinse with 18°C ​​water for 11min, drain and air-dry naturally to obtain brown silk according to the present invention. Silk. Embodiment 3 improves the method of brown fiber toughness:

[0038] (1) One time decoction: 300g water, 160g brown silk, 60g ethyl acetate, 60g wormwood, 13g benzoic acid, 30g locust bean, 6g sodium hydroxide are added in the first processing container by weight to decoct, After obtaining the boiled off brown silk, the boiled off time is 60min, and the boiled off temperature is 94°C.

[0039] (2) Brown silk rubbing treatment: the brown silk obtained by boiling off once is moistened with glutinous rice water, rubbed, and dried in the air to obtain dried brown silk.

[0040] (3) Secondary decoction: 150g of kerosene, 120g of ethyl acetate, 100g of vegetable oil, and 90g of polyvinyl acetate are put into the second ...

Abstract

The invention provides a method for improving the toughness of palm fibers. The method comprises the following steps: primary boiling of the palm fibers by using argy wormwood, ethyl acetate, benzoic acid, locust beans and sodium hydroxide, secondary boiling of the palm fibers by using kerosene, ethyl acetate, vegetable oil and polyvinyl acetate, steaming, rinsing and post-treatment. The method can enhance the internal intermolecular force of the palm fibers, and has a moisturizing effect, so that the toughness of the palm fibers is high; and test shows that the toughness of the palm fibers processed through the method for improving the toughness of the palm fibers is improved by 32%, and the obtained palm fibers have beautiful color, are yellowish green, and meet the raw material requirements of palm fiber products.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a method for improving the toughness of brown silk. [0002] technical background [0003] With the improvement of living standards, natural and environmentally friendly household products are more and more favored by consumers. Palm silk, the fiber of palm tree leaf sheaths, is reddish brown, tough and elastic. It was originally a raw material for weaving coir raincoats and ropes. It has the characteristics of high flexibility, good air permeability, strong water resistance, good ductility, and low cost. In recent years, more and more products such as mattresses and cushions are made of brown silk. Although it has strong applicability and good air permeability, its toughness is not ideal. After a long time, brown silk is easy to break after dehydration, and brown cushions are easy to partially collapse. The problem of the flexibility of its brown silk has always af...
