Problems solved by technology

The existing problems are: 1. After fully combing, the toughness and skin-adherence of the non-woven fabric produced in the wet state are not high. When the mask is used, the user's face must remain still. Once there is a facial relaxation action , it will cause the mask to detach from the skin
2. The permeability of the non-woven fabric produced is not high, which cannot meet the high penetration and high absorption requirements of the beauty liquid in the mask
3. The softness of non-woven fabrics is poor, and it can only be used as the base material of products in a wet state such as masks, and after being used once in a wet state, its softness will be even worse, and the water absorption and tensile strength will also be greatly reduced, so It is useless after one use, which is a waste of material

Embodiment 1

[0023] Embodiment 1: with reference to attached figure 1 . A highly flexible non-woven fabric, including a non-woven fabric layer; the non-woven fabric layer is made of ultra-fine and ultra-short fine-denier viscose, polyester, polypropylene, chitin or tencel and other fine-denier fibers as raw materials, and each fine-denier fiber is mutually Messy entanglement into non-woven fabrics; the length of fine denier fibers is 3mm or 4mm.

Embodiment 2

[0024] Embodiment 2: with reference to attached figure 2 . A kind of manufacture method of above-mentioned highly flexible non-woven fabric, comprises the following steps:

[0025] ① Prepare raw materials, using polyester and tencel with a length of 1-5mm as raw materials;

[0026] ② After mixing the two kinds of raw material fibers according to a certain ratio, the raw material fiber slurry is formed;

[0027] ③ The raw fiber slurry flows into the forming machine for carding, and dehydrates on the forming net to form the first layer of fiber web;

[0028] ④The forming net in the forming machine is installed obliquely, and the angle between the forming net and the horizontal plane is 10°~30°. A high-pressure pre-spun thorn head is also installed above the forming machine. The first layer of wet fiber web is spunlace pre-entangled;

[0029] ⑤ Raw material fiber slurry flows into the forming machine to form the second layer of fiber web on the basis of the first layer of fi...

Abstract

The invention relates to a high-softness nonwoven fabric, which is utilized as a nonwoven fabric of a base material of products, such as masks, can effectively save materials, has high-efficiency skin-closed permeability and strong toughness, is very soft and delicate and has higher tensile strength and hydroscopic property, and a manufacturing method of the high-softness nonwoven fabric. The high-softness nonwoven fabric is manufactured by the following steps of by utilizing fine fiber with the length of 1-5mm as a raw material, through a high-pressure pre-spunlace head of a forming machine, carrying out pre-spunlace winding on a fiber web on a formed web, carrying out main spunlace reinforcing and winding, drying and coiling.

Description

technical field [0001] The invention relates to a non-woven fabric, in particular to a highly flexible non-woven fabric used as a base material for facial masks, cleansing paper, wet wipes and other products and a manufacturing method thereof. Background technique [0002] Non-woven fabrics are used as the base material of facial masks, cleansing paper, wet wipes and other products, which require high hygroscopicity and toughness in wet state. For high-end mask products, it must also have considerable permeability and fit with the skin. The invention patent with the patent application number 201110401665.X discloses "a production method of spunlace cotton blended spunlace nonwoven fabric", which uses a flat carding machine to replace the carding machine traditionally used in the nonwoven production line. After the fibers are fully carded, they are pre-wetted and hydroentangled. The existing problems are: 1. After fully combing, the toughness and skin-adherence of the non-w...
