Problems solved by technology

[0004] Under this development trend, the research on rush fibrosis is also increasing day by day. There are mainly two aspects of research: 1. Extraction of rush fiber. The main problems faced by this method are the limitation of fiber extraction production equipment and the Fiber strength is low, fiber is short, and the extraction rate of fiber is low about 20%; Two, weaving rush pulp produces man-made fiber, but also there are following problems: 1) rush fiber is too short, and pulping rate is very low, pulp The pulp yield is about 15%; 2) According to the previous sulfonation of the factory, the chemical properties of the obtained viscose fiber are similar to those of ordinary viscose fiber
Because the pulping rate of rush is too low, processing and producing viscose in this way requires high cost, large input, and low output, and the characteristics of the produced viscose staple fiber are not obvious

Embodiment 1

[0031] Take a certain amount of rush powder and add it into water at a temperature of 25°C in a ratio of 500g / L to dissolve, stir until the dissolution is complete, and make an aqueous solution of rush powder.

[0032] The obtained rush powder aqueous solution is added to the viscose spinning stock solution with a fiber mass fraction of 10% in the proportion of 10% of the mass of the viscose fiber spinning stock solution, stirred and dispersed, left to stand for vacuum degassing, and then according to the conventional wet method Spinning and spinning process, enter coagulation bath through candle filter and spinneret after measuring by metering pump; Described coagulation bath is made up of 100g / L sulfuric acid, 320g / L sodium sulfate and 15g / L zinc sulfate, and temperature is 40 ℃, the elongation rate is 100%, the spinning speed is 50m / min, and then sprayed according to the conventional wet spinning process, and then the rush viscose fiber is obtained through the oiling and dry...

Embodiment 2

[0035] Such as image 3 Shown, a kind of improvement to above-mentioned preparation method: obtain rush viscose long fiber and adopt the spinneret molding process of conventional wet spinning long filament to comprise the following steps: rush grass powder aqueous solution and viscose fiber spinning stock solution blending—> Spinneret spinning—> coagulation bath—> godet—>hot water washing—>acid washing—>water washing—>boiling water drawing—>winding—>drying, and finally rush viscose long fibers are obtained.

[0036] Obtain rush viscose staple fiber by processing in above example 1, carry out following performance analysis:

[0037] 1) Color and cross section

[0038] Such as Figure 4 As shown, the color of the obtained rush viscose fiber retains the color of the rush, and the obtained fiber is green and environmentally friendly, meeting people's pursuit of green life quality. Such as Figure 5 As shown, the cross-sectional structure of the fiber was observed through an el...

Abstract

The present invention relates to the technical field of man-made fibers, particularly to viscose fibers containing mat rush and a preparation method thereof. The present invention provides viscose fibers containing mat rush, wherein the viscose fibers comprise viscose fibers and mat rush powder, and are characterized in that mat rush is subjected to mechanical grinding processing to obtain the mat rush powder, the mat rush powder is prepared into a mat rush powder aqueous solution, the mat rush powder aqueous solution is added to a viscose spinning original liquid, and molding is performed according to a conventional wet spinning process to obtain the mat rush viscose fibers, wherein the mat rush powder content in the fibers is 1-10%. According to the present invention, the mat rush viscose fibers have characteristics of color similar to mat rush, green environmental protection, moisture absorption and releasing, anti-bacterial function and deodorant function, and are suitable for the summer home textile products, and the process of the preparation method is reasonable and simple, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of man-made fibers, in particular to a viscose fiber containing rush and a preparation method thereof. Background technique [0002] The central pith of the rush stem is composed of numerous white porous and loose stellate cells, also known as spongy tissue. All kinds of products woven with rush have the functions of ventilation, moisture absorption and cooling, especially the stem of rush has the function of regulating dryness and humidity. It can keep moderately dry in summer, making people's skin feel very comfortable, and has good thermal insulation performance in winter. Therefore, rush woven fabrics have become an indispensable household daily necessities in people's daily life, and are also a unique indoor fashion decoration. Consumers love it. [0003] Since the 21st century, the design, production and use of rush products have increasingly relied on the technology and technical strength of the tex...
