Embodiment 1

[0046] 2.0 g of cellulose pulp board (DP: 800) was pulverized into flakes, then placed in an electric blast drying oven, and dried at 100° C. for 24 hours until the moisture content was 0.5%.

[0047] Add the pretreated cellulose paddle to the prepared 18g ionic liquid, which is composed of [BMIM]Ac, alkyl quaternary ammonium salt, and DMSO in a weight ratio of 1:3:7. ionic liquid;

[0048] Under the condition of heating and stirring, the dissolution reaction occurs. The heating and stirring environment is as follows: the stirring rate is 250 rpm, the oil bath temperature is 65°C, and the stirring time is 2h.

[0049] Add 1.8 g of amino silicone oil to the obtained pure cellulose solution, and continue the dissolution reaction under the environment of heating and stirring. The heating and stirring environment at this time is as follows: the stirring rate is 350 rpm, the oil bath temperature is 68° C., and the stirring time is 3 hours.

[0050]The prepared blended spinning s...

Abstract

The invention relates to a flexible fiber having flame retardancy and a preparation method thereof. The flexible fiber is prepared from 1.5 to 2.5 parts by weight of a cellulose pulp plate, 17 to 19 parts by weight of an ionic liquid, 1.5 to 2 parts by weight of amino silicone oil and 19 to 21 parts by weight of hydroxyl silicone oil. The preparation method comprises putting the cellulose pulp plate in the ionic liquid to obtain a cellulose solution, adding the amino silicone oil into the cellulose solution to obtain a blended spinning liquid, carrying out ultrasonic treatment and standing to remove bubbles, carrying out spinning through a dry-jet wet spinning technology, collecting fibers, soaking the fibers in deionized water, carrying out drying, dipping the fibers in the hydroxyl silicone oil for surface coating and carrying out drying. The preparation method has simple processes. The prepared fiber is soft, has flame retardant effects and provides broad prospects for the application of cellulose fiber products.

Description

technical field [0001] The invention belongs to the field of flame-retardant materials, and in particular relates to a flexible fiber with flame-retardant properties and a preparation method thereof. Background technique [0002] With the continuous development of science and technology and the gradual improvement of people's consumption level, the demand for cellulose and its products and the requirements for its performance are also increasing. At the same time, the fire caused by the burning of fiber products has become one of the major disasters in modern society, seriously threatening the safety of people's lives and property. Therefore, flame-retardant fiber materials for preventing fires have become a social problem that cannot be ignored. [0003] Therefore, the research on textile flame retardant materials has developed rapidly, and at the same time, the requirements for flame retardant performance, multifunctionality, environmental protection and durability of tex...
