Embodiment 1

[0034] The preparation method of modified jute fiber is specifically:

[0035] (1) According to the mass ratio of 1:1.5, dissolve the extract of Acanthopanax in 80% ethanol, add diatomaceous earth in proportion, dry it after fully stirring, dry it under reduced pressure to constant weight, and grind it into nanoparticles; 90nm.

[0036] (2) take jute fiber pulp as raw material, utilize conventional viscose process to make viscose collagen solution, add the described nano-particles that account for hemp fiber content 16% in the viscose collagen solution step, then prepare through known viscose glue such as mixing The blended spinning solution is prepared by the process, and then spun through a coagulation bath, and the as-spun tow is drawn to obtain a shaped tow, and the obtained tow is cut, desulfurized, bleached, oil bathed, and dried to obtain Modified jute fiber. Among them, the coagulation bath includes sulfuric acid 75g / L, zinc sulfate 6.8g / L, sodium sulfate 320g / L; des...

Embodiment 2

[0041]The preparation of modified jute fiber is identical with embodiment 1.

[0042] A degradable antibacterial composite non-woven fabric, the components include: by weight, 22 parts of modified jute fibers, 22 parts of green sandalwood bark fibers, and 12 parts of grass coral fibers.

[0043] The difference between the preparation of the non-woven fabric and that of Example 1 is that the number of laying layers is set to 20, the needle-punching frequency is 436 r / min, and the thickness of the needle-punched non-woven fabric obtained is 2.9 mm.

Embodiment 3

[0045] The preparation of modified jute fiber is identical with embodiment 1.

[0046] A degradable antibacterial composite non-woven fabric, the components include: by weight, 24 parts of modified jute fiber, 18 parts of green sandalwood bark fiber, and 10 parts of grass coral fiber.

[0047] The difference between the preparation of the non-woven fabric and that of Example 1 is that the number of laying layers is set to 24, the needle-punching frequency is 445 r / min, and the thickness of the needle-punched non-woven fabric obtained is 4.2 mm.

Abstract

The invention discloses degradable antibacterial composite non-woven fabric and application thereof, and relates to the technical field of non-woven fabric. The degradable antibacterial composite non-woven fabric specifically comprises modified jute fibers, pteroceltis tatarinowii bark fibers or alfalfa crude fibers and sarcandra glabra fibers, wherein the modified jute fibers are prepared by modifying bidens bipinnata extracts and diatomite. The non-woven fabric prepared by the invention has excellent mechanical properties and air permeability and good wear resistance, has higher antibacterial and bacteriostatic effects, and good long-acting bacteriostatic effect, is resistant to washing, biodegradable and high in anti-pollution capability, and can be widely applied to the fields of beddings, clothes and medical supplies.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to degradable antibacterial composite non-woven fabrics and applications thereof. Background technique [0002] Non-woven fabrics (English name: Non Wowen), also known as non-woven fabrics, are composed of directional or random fibers, and are moisture-proof, breathable, flexible, light in weight, non-combustible, non-toxic, non-irritating, rich in color, and low in price. , Recyclable and so on. For example, polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. It is called cloth because it has the appearance and certain properties of cloth. [0003] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentangleme...
