Embodiment 1

[0051] Using wet spinning method. Add 3 g of eucommia gum to a 250 mL reaction bottle, add 120 mL of solvent chloroform at the same time, stir at room temperature for 12 hours until it is fully dissolved, and obtain a spinning slurry with a concentration of 2.5 wt%. After the filtered spinning solution is metered by a peristaltic pump, it is squeezed into the coagulation bath through a 23# spinning needle. The injection rate of the peristaltic pump is 300 μL / min, and the coagulation bath is filled with methanol solvent; Stir at a constant speed, and the rotation speed of the magnet is 200r / min. The primary filaments formed after solidification are drawn under the action of the solvent rotation of the coagulation bath to make them directional stretched and thinned. . The obtained eucommia gum fiber is a spherical, agglomerate or other shaped product, such as figure 1 As shown, the monofilament was stripped off to measure its mechanical properties.

Embodiment 2

[0053] Repeat Example 1, the preparation method of Eucommia gum elastic fiber is the same, the difference is the processing method of the test sample. The prepared eucommia gum fiber is a spherical, agglomerated or other shaped product. The monofilament is stripped off, and 50 fibers are rearranged to form a multifilament, and its mechanical properties are measured.

Embodiment 3

[0055] Repeat Example 1, the preparation method of Eucommia gum elastic fiber is the same, the difference is the processing method of the test sample. The obtained eucommia rubber fiber is spherical, group or other shaped products, the monofilament is stripped off, rearranging 50 fibers and twisted to form eucommia rubber elastic fiber yarn, the twist is 150n / m, and its mechanical properties are measured performance.

Abstract

The invention discloses a bio-based eucommia gum elastic fiber and a fiber film and a preparation method thereof. The high-molecular-weight bio-based eucommia gum is dissolved, and the obtained low-concentration solution is subjected to wet spinning, electrostatic spinning or dry spinning. The eucommia gum elastic fiber and fiber film are prepared. The elastic fiber prepared by the method of the invention is thinner, the fiber film is thinner, has excellent mechanical properties and shape memory function, and can be used in the development of new products such as fabrics and high-grade clothes. The method of the present invention is simple and efficient, and the prepared Eucommia gum elastic fiber and fiber film are a new type of Eucommia gum product, which expands the traditional idea that Eucommia gum is mainly used in the field of rubber-plastic, and is conducive to accelerating its comprehensive development and utilization. .

Description

technical field [0001] The invention belongs to the field of textile materials, and relates to a bio-based eucommia gum elastic fiber and fiber film, a preparation method and application thereof. Background technique [0002] In general, elastic fibers refer to synthetic fibers with high elongation at break, low modulus, and high resilience. Generally speaking, the elasticity of the fiber can be measured from three aspects: one is the lower modulus, that is, the external force required for deformation is smaller; the second is the greater elongation; the third is the higher elastic recovery performance . Elastic fiber textiles are comfortable to wear, have good shape retention and wrinkle resistance, are widely used, and have become one of the current mainstream textile products. At present, underwear, swimwear, sportswear, sportswear, leisure and outdoor clothing are almost all selectively added with some elastic fibers. With the improvement of people's requirements for ...
