Benefits of technology

The invention is a method for making a fiber that improves its solubility and strength while lowering the process temperature. This leads to better energy efficiency and reduced recycling costs. The method also allows for the production of fibers with higher strength using both wet and dry-jet wet spinning methods.

Problems solved by technology

), which causes the solute degradation and energy consumption.
Besides, because NMMO is a strong oxidizing agent, it is required to add stabilizing agent in the process additionally, so the recycling cost is higher.

experimental example

[0030]To prove the excellent fiber strength of the fiber prepared by the fiber preparation method of the invention, and the overall process temperature is lower with energy conservation effects, the following Experimental Examples are performed.

Fiber Preparation

example 1

[0031]48.5g ionic liquid 1-ethyl-3-methylimidazolium acetate ([EMIM]OAc) and 1.5 g (3 wt %) KOAc are mixed and dissolved at 60° C. to form a mixing solution. Afterwards, 5 g cellulose is added, and mixed and dissolved at 60° C. to form a spinning viscose. The spinning viscose is used as a material to perform a spinning process, and a cellulose fiber is formed through a dry-jet wet spinning method.

example 2

[0032]48.5g ionic liquid [EMIM]OAc and 1 g (2 wt %) KOAc and 0.5 g (1 wt %) KBr are mixed and dissolved at 60° C. to form a mixing solution. Afterwards, 5 g cellulose is added, and mixed and dissolved at 60° C. to form a spinning viscose. The spinning viscose is used as a material to perform a spinning process, and a cellulose fiber is formed through a dry-jet wet spinning method.

Abstract

A preparation method of a fiber is provided. In the preparation method of the fiber, a polymer is dissolved in a mixing solution of an ionic liquid and a salt to form a spinning viscose, wherein the salt includes KCl, KBr, KOAc, NaBr, ZnCl2 or a combination thereof. Afterwards, the spinning viscose is used as a material to perform a spinning process so as to form a fiber.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 103142137, filed on Dec. 4, 2014. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a preparation method of a fiber and a spinning viscose, and more particularly relates to a preparation method of a regenerated fiber and a spinning viscose.[0004]2. Description of Related Art[0005]In recent years, scientists actively work in manufacturing regenerated fibers by dissolving existing polymer materials so as to replace the consumption of natural fibers. The regenerated fiber can be widely applied in a variety of industries, such as home textile, thin film, flexible electronic display, cosmetics, medical drugs and food additive.[0006]In the process of manufacturing regenerated fiber, it is usually ...
