Embodiment 1

[0018] The preparation method of this pineapple leaf fiber comprises the following steps:

[0019] A, the pineapple blade is mechanically processed to obtain the pineapple blade fiber raw material;

[0020] B. Put the pineapple leaf fiber raw material prepared in step A into the soaking liquid, soak for 1 hour, take it out, and wash it until its pH value reaches 6.8; wherein, the soaking liquid is made of sulfuric acid, chlorine dioxide, water by volume It is prepared by mixing sulfuric acid: chlorine dioxide: water=3:2:1000;

[0021] C. Put the pineapple leaf fiber raw material processed in step B into the cooking equipment, then add 30% sodium hydroxide, water glass, urea, trisodium phosphate and sodium sulfide to the cooking equipment, and heat to 120°C , insulated and boiled for 0.5 hour, taken out, washed with water until its pH value reached 6.8; wherein, the pineapple leaf fiber raw material and concentration after the treatment of step B were 30% sodium hydroxide, wat...

Abstract

The invention discloses a method for preparing pineapple leaf fibers, belonging to the technical field of textile industry. The method comprises the following steps: performing mechanical treatment, thereby obtaining pineapple leaf fiber raw materials; pre-impregnating in acid, and washing until the pH value is 6.8-7.0; cooking, and washing until the pH value is 6.8-7.0; soaking, and washing until the pH value is 6.8-7.0; soaking, and washing until the pH value is 6.8-7.0; and dewatering, shaking, drying, thereby obtaining the product. The invention provides a method for preparing pineapple leaf fibers, and the pineapple leaf fibers prepared by the method are good in physical performances and high in purity.

Description

technical field [0001] The invention belongs to the technical field of textile industry, in particular to a preparation method of pineapple leaf fiber. Background technique [0002] Pineapple, commonly known as pineapple, is native to the dry tropical mountains of Brazil, Argentina, and Paraguay. It was introduced to various regions in southern China between the end of the 16th century and the 17th century. [0003] Pineapple leaf fiber, also known as pineapple hemp, is a fiber extracted from pineapple leaves and belongs to leaf fibers. Pineapple leaf fiber is white in appearance, soft and smooth, and feels like silk, so it is called pineapple silk. In addition, pineapple leaf fiber can be blended with natural fiber or synthetic fiber, and the woven fabric is easy to print and dye, sweat-absorbent, breathable, crisp and wrinkle-free, and comfortable to wear. [0004] At present, the pineapple leaf fiber is mainly obtained by manual or mechanical stripping. The mechanical s...
