Problems solved by technology

[0002] Although the wood pulp fiber products produced by the single traditional wet-laid technology are degradable and beneficial to the protection of the environment, they are not popular due to the defects of poor softness, low strength and friable slag. For this reason, chemical binders are often added in the process of processing. Although the use of binders can make up for the lack of low strength and fragility, because the binders used as additives are prone to chemical reactions, the impact on product quality Stability constitutes an impact; nonwoven products produced by a single textile staple fiber through the spunlace process, that is, the spunlace process, are neglected by people due to defects such as rough surface, low hygroscopicity, and non-degradability.

Embodiment 1

[0021] A) to produce wood pulp fiber web, the wood pulp short cellulose pulp board that will buy from the market is 3mm, average fineness is 800 purpose wood fiber processing into material tank soaking and dissolving, then use papermaking The hydraulic pulverizer commonly used in the industry performs hydraulic pulverization to obtain wood pulp cellulose slurry, and introduces the wood pulp cellulose slurry into the storage tank with a conveying device such as a feeding pump, and the concentration of wood pulp cellulose in the storage tank The control is 3.5%, and then the pipeline pump transports the wood pulp cellulose in the storage tank to the wet-laid machine for suction and dehydration to form a web. After suction and dehydration, the moisture content is 80%, and the wood pulp is stripped by the guide roller and Pulp fiber web output, the obtained grammage is 125g / m 2 The wet state wood pulp fiber web, stand-by;

[0022] B) produce the textile fiber web, the polyester s...

Embodiment 2

[0025] A) produce wood pulp fiber net, the bamboo pulp short cellulose pulp board that will buy from the market is that 15mm, average fineness are processed into the bamboo fiber of 900 purpose bamboo fiber by fiber length and send into bucket soaking and dissolving, then use papermaking The customary water pulverizer in the industry carries out hydraulic pulverization to obtain bamboo pulp cellulose slurry, and the bamboo pulp cellulose slurry is introduced in the slurry storage tank with a conveying device such as a feed pump, and the concentration of the bamboo pulp cellulose in the slurry storage tank The control is 3%, and then the bamboo pulp cellulose in the storage tank is transported by the pipeline pump to the wet-laid machine for suction and dehydration to form a web. Pulp fiber web output, the obtained grammage is 120g / m 2 The wet state bamboo pulp fiber net, stand-by;

[0026] B) use the polypropylene staple fiber that is 30mm and the fineness is 2 deniers (2dtex...

Embodiment 3

[0029] A) produce wood pulp fiber net, only change fiber length into 8mm, average fineness into 850 orders, change the concentration control of wood pulp cellulose in the storage tank into 2.5%, the water content after suction dehydration is 85%, and the grammage of the wood pulp fiber net obtained is 16.7g / m 2 , all the other are the same as the description of the A) step of embodiment 1;

[0030] B) produce the textile fiber web, only change the short textile fiber to polypropylene fiber, nylon fiber and viscose fiber with a weight ratio of 1:1:1, the length of each of the above-mentioned fibers is 45mm, and the fineness is each 3 deniers (3dtex ), according to the description of step B) in Example 1, the grammage obtained is 66g / m 2 , A wet textile fiber web made of polypropylene, nylon and viscose fibers with a moisture content of 28%;

[0031] C) Composite forming, according to the description of step C) in Example 1, obtain wood fiber and account for 5% (2.5g / m 2 ), w...

Abstract

The invention discloses a degradable non-woven fabric and belongs to the technical field of the processing of non-woven products. The degradable non-woven fabric consists of the following raw materials by weight: 1 to 80 parts of short lignosol fiber, and 99 to 20 parts of short textile fiber. The technical proposal disclosed by the invention combines the short lignosol fiber and the short textile fiber into the degradable non-woven fabric, thus not only making up for the disadvantages in the prior art that single lignosol fiber products have bad softness and low intensity, and are fragile and easy to generate dregs, but also eliminating the disadvantages in the prior art that single non-woven fabric products of the short textile fiber have rough surface, bad hydroscopic property and non-degradable property, and obtaining the degradable non-woven fabric which has good softness, ideal intensity and excellent hydroscopic property, and is easy to degrade after disuse and favorable for environmental protection.

Description

technical field [0001] The invention belongs to the technical field of nonwoven product processing, in particular relates to a degradable nonwoven fabric, and also relates to a manufacturing method of the nonwoven fabric.
