Embodiment Construction

[0022] A functional flame-retardant fiber, including cellulose, is characterized in that: it also includes nano-scale additive powder of tourmaline and silicon dioxide; its components are by weight percentage:

[0023] Cellulose: 75% to 95%;

[0024] Nanoscale additive powder of tourmaline and silicon dioxide: 5% to 25%;

[0025] Wherein: the nano tourmaline powder accounts for 40%-70% of the total weight of the nano-scale additive powder, and the silicon dioxide accounts for 30%-60% of the total weight of the nano-scale additive powder. The volume percentage of the nano-scale additive powder with nano particles below 100nm accounts for more than 70% of the total volume.

[0026] The production method of a kind of functional flame-retardant fiber of the present invention, specifically has the following steps according to the production process sequence:

[0027] (1) Select tourmaline and silicon dioxide and grind them step by step. Using the principle of centrifugal force f...

Abstract

The present invention relates to a functional flame-retardant fiber and a production method thereof. The main feature is that it also contains tourmaline and silicon dioxide nano-scale additive powder; its components are: cellulose: 75% to 95%; tourmaline and Nano-scale additive powder of silicon dioxide: 5% to 25%; the production process sequence includes the following steps: making tourmaline and silicon dioxide into nano-scale additive powder respectively; uniformly mixing nano-scale additive powder with cellulose Mixing, the nano-scale additive powder is 5% to 25% by weight; a static mixer is used to prepare a spinning solution by melting and blending; spinning to make a flame-retardant fiber. It has low cost, simple process, environmental protection and no pollution, can continuously emit far infrared rays and permanently release negative ions, and has a wide range of applications.

Description

technical field [0001] The invention designs a production method of flame-retardant fibers, especially a production method of novel flame-retardant fibers with health care functions such as emitting far infrared and releasing negative ions. Background technique [0002] Fire breeds human civilization and brings us light and warmth, but sometimes it also causes disasters to people and even devours precious lives. Most textiles are igniters, and according to statistics, fires ignited by textiles account for about 50%. Therefore, in some specific occasions, such as hotels, restaurants, exhibition halls, gymnasiums, carriages, bedrooms, etc., cotton bedding, curtains and furniture cloth, as well as protective equipment for specific types of workers, must be treated with flame retardant. [0003] At present, there are mainly two methods for flame retardant fibers on the market. One is to post-treat textile fibers with flame retardants. Most of the flame retardants are chemical r...
