Problems solved by technology

Most of the commonly used non-woven fabrics are made of cotton, wool, hemp fibers and viscose fibers. Due to the poor toughness of natural cotton and hemp fibers, the strength and durability of existing non-woven fabrics are relatively low compared with textile fabrics. Poor, non-woven fabrics are prone to mold and bacterial propagules in a humid environment, and cannot be used excessively for a long time

preparation example Construction

[0023] The present embodiment provides a kind of preparation method of novel plantain core fiber nonwoven fabric, such as figure 1 As shown, the following steps are included: preparation of S10 plantain core fiber, selecting fresh and mature plantain trees and manually processing to obtain plantain core fiber. S20 Pretreatment of plantain core fibers, degumming and drying the plantain core fibers to obtain plantain core fibers to be beaten. Preparation of S30 slurry, injecting bamboo pulp and appropriate amount of ultrapure water into the beater for 3-6 times for beating for 10-25 seconds each time, then adding the plantain core fiber to be beaten for 1-4 times for beating for a single time beat for 10-25 seconds each time to obtain a slurry suspension of plantain core fiber and bamboo pulp. S40 forming a web, pour the slurry suspension evenly into the former, and mix evenly, drain the water in the former to form a fiber web, and finally put the fiber web in a room with a tem...

Embodiment 1

[0029]S11 Collect fresh and mature banana trees, peel off the outer pseudostem to obtain the core of the banana stem, wash with clean water, and drain the surface water.

[0030] S12 Use a knife to place the plantain core at a distance of 2 cm from one end, and gently draw a circle on the bast part perpendicular to the axial direction of the plantain core.

[0031] S13 quickly breaks off the incision, and slowly pulls it to both sides at a uniform speed to obtain the plantain core fiber.

[0032] S21 alkali treatment, alkali treatment of the plantain core fiber in a sodium hydroxide solution with a temperature of 80° C. and a mass concentration of 10 g / L for 2.5 hours, and washing at 40° C. for several times before use.

[0033] S22 Acid treatment: acid-treat the alkali-treated plantain core fibers in a sulfuric acid solution with a mass concentration of 0.3 g / L for 10 minutes, wash with water several times at 40° C., and dry in an oven at 75° C. for 2.5 hours to obtain planta...

Abstract

The invention provides novel plantain core fiber non-woven fabric and a preparation method thereof. The preparation method comprises the following steps that S10, fresh and mature plantain trees are selected, and manual treatment is carried out to obtain plantain core fibers; S20, after degumming and drying treatment is carried out on the plantain core fibers, plantain core fibers to be pulped areobtained; S30, pulp is prepared, and bamboo pulp and the to-be-pulped plantain core fibers are pulped to prepare pulp turbid liquid of the plantain core fibers and the bamboo pulp; S40, the pulp turbid liquid is uniformly poured into a forming device and is uniformly mixed to obtain a fiber net; and S50, the fiber net is subjected to spunlace reinforcement, and the plantain core fiber non-woven fabric is obtained. According to the novel plantain core fiber non-woven fabric and the preparation method thereof, plantain cores are selected as main materials, the plantain core fiber non-woven fabric is prepared by adopting a wet-process net forming and spunlace process, the application range of the plantain core fibers is expanded, and the novel plantain core fiber non-woven fabric has positive effects on reasonable utilization of natural plant resources and environmental protection.

Description

technical field [0001] The invention relates to the technical field of textile materials, in particular to a novel plantain core fiber nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics are sheets, webs or batts (excluding paper, woven fabrics, tufted fabrics, Stitch-bonded fabrics with stitching yarns and wet-milled felts). The fibers used can be natural fibers or chemical fibers; they can be short fibers, filaments or fibrous objects formed on the spot. Nonwovens break through the traditional textile principles and integrate the knowledge of textiles, chemicals, plastics, papermaking, modern physics, chemistry and other disciplines. Wide application and other characteristics, the advantage is that it does not produce lint, is strong, durable, and silky soft. It is also a kind of reinforcing material, and it also has a cotton feel. Compared with cotton fabrics, non-woven bags are easy to form The cost is cheap. Most of the ...
