Problems solved by technology

Although the non-woven fabric of this invention patent can be completely biodegradable and will not pollute the environment, there are still several problems: 1. The dust-free paper is composited on at least one side of the non-woven fabric base layer through the spunlace process, The strength between the dust-free paper and the base cloth layer is not high, and peeling and desquamation will occur during use; 2. It cannot be completely decomposed at the moment of water flushing, and cannot be used for toilet cleaning; 3. There are various production processes, and papermaking is required machine; and the process requirements are relatively high, and the thickness of the dust-free paper made of wood pulp fibers must be moderate

Embodiment 1

[0017] Embodiment 1: with reference to attached figure 1 . A water flushing degradable non-woven fabric, comprising a non-woven fabric layer 1; the special-shaped viscose fibers and wood pulp fibers in the non-woven fabric layer 1 are mixed with each other, and entangled with each other; the special-shaped viscose fibers Both viscose and wood pulp fibers are short fibers, and are hydrogen bonded; the ratio of shaped viscose fibers and wood pulp fibers in the non-woven fabric layer 1 is 1:1.

Embodiment 2

[0018] Embodiment 2: with reference to attached figure 2 . On the basis of embodiment 1, a kind of preparation method of water washing degradable non-woven fabric comprises the following steps:

[0019] ① Using special-shaped viscose fiber and wood pulp fiber as raw materials for opening and mixing;

[0020] ②The fiber raw materials are mixed and carded through the wet forming process to form a fiber mesh layer;

[0021] ③Through the spunlace process, the front and back sides are entangled and reinforced;

[0022] ④ After post-processing (dyeing, etc.), drying, and winding, a water-washed degradable non-woven fabric is obtained.

Abstract

The invention relates to a water-flushing degradable non-woven fabric and a production method thereof. Profiled viscose fibers and wood pulp fibers are directly used as raw materials and are opened and mixed, then the profiled viscose fibers and the wood pulp fibers are mutually twisted through wet process formation and spun-lacing reinforcement, hydrogen bonds are formed between the profiled viscose fibers and the wood pulp fibers and finally drying is performed to obtain the water-flushing degradable non-woven fabric. By adopting the scheme, the strength of the water-flushing degradable non-woven fabric is high, the water-flushing degradable non-woven fabric can be quickly and fully degraded under the effect of water flushing and the production process is simple.

Description

technical field [0001] The invention relates to a water-washing degradable non-woven fabric which can be rapidly decomposed under water washing and a manufacturing method thereof, belonging to the technical field of non-woven fabric manufacture. Background technique [0002] The invention patent with Chinese patent application number 200810062557.2 discloses a completely biodegradable medical / industrial non-woven fabric and its production process. The non-woven fabric of this invention patent includes a wood pulp fiber layer and a spunlace non-woven fabric base cloth layer, at least one surface of the spunlace non-woven fabric base cloth layer is compounded with a wood pulp fiber layer; Then, the dust-free paper is compounded on at least one side of the non-woven fabric base layer by spunlace technology, and then the non-woven fabric is obtained after drying, trimming, and winding. Although the non-woven fabric of this invention patent can be completely biodegradable and wi...
