Embodiment 1

[0041] Example 1: The treatment steps of non-woven fabrics are as follows: (1) Configure the treatment solution: dissolve polyvinyl alcohol with a degree of polymerization of 1700 and an alcoholysis degree of 97% in boiling water for 1 hour, and then add the above-mentioned synthesized water-based polyacrylic acid respectively Ester WPEA-1, water-based polyisocyanate crosslinking agent, stir vigorously until mixed evenly; among them, polyvinyl alcohol (PVA) accounts for 0.4% of the total mass of the solution, polyacrylate (PA) accounts for 0.6% of the total mass of the solution, and water-based polyisocyanate The cross-linking agent accounts for 0.03% of the total mass of the solution. (2) Treatment: In this example, a non-woven fabric combined with 70% viscose fiber and 30% polyester fiber is selected, and the weight of the non-woven fabric is 30g / m 2 ; Use the treatment solution in step (1) to perform padding treatment on the non-woven fabric once, and the excess rate is 18...

Embodiment 2

[0048] Example 2: The treatment steps of non-woven fabrics are as follows: (1) Prepare the treatment solution: dissolve polyvinyl alcohol with a degree of polymerization of 1750 and an alcoholysis degree of 98% in boiling water for 1 hour, and then add water-based polyacrylate WPEA-1 , water-based polyisocyanate cross-linking agent, stir vigorously until mixed evenly; wherein polyvinyl alcohol (PVA) accounts for 0.2% of the total mass of the solution, water-based polyacrylate (PA) accounts for 2% of the total mass of the solution, water-based polyisocyanate cross-linking agent Accounting for 0.022% of the total mass of the solution. (2) Treatment: In this example, a non-woven fabric combined with 70% viscose fiber and 30% polyester fiber is selected, and the weight of the non-woven fabric is 30g / m 2 ; Put the non-woven fabric into the treatment liquid of step (1) and perform padding treatment once, and the excess rate is 180%. (3) Drying: Dry the non-woven fabric in step (2)...

Embodiment 3

[0049] Example 3: The treatment steps of non-woven fabrics are as follows: (1) Configure the treatment liquid: add polyvinyl alcohol with a degree of polymerization of 1750 and an alcoholysis degree of 98% into boiling water for 1 hour, and then add water-based polyacrylate WPEA-1 , water-based polyisocyanate cross-linking agent, stir vigorously until mixed evenly; among them, polyvinyl alcohol (PVA) accounts for 1% of the total mass of the solution, polyacrylate (PA) accounts for 3% of the total mass of the solution, and water-based polyisocyanate cross-linking agent accounts for 1% of the total mass of the solution. 0.4% of the total mass of the solution.

Abstract

The invention provides a non-woven fabric for manufacturing dust-free wiping paper. The non-woven fabric for manufacturing the dust-free wiping paper comprises a non-woven fabric containing cellulosic fibers, wherein the non-woven fabric is prepared by treating a treatment solution containing polyvinyl alcohol, water-borne polyacrylate and a water-borne isocyanate cross-linking agent. The provided non-woven fabric is firm, high in cleanliness and soft. The invention also provides a method for manufacturing the non-woven fabric. The manufacturing method comprises the following steps: preparing the treatment solution containing polyvinyl alcohol, water-borne polyacrylate and a water-borne isocyanate cross-linking agent; padding the non-woven fabric containing cellulosic fibers by adopting the treatment solution, and baking. The method is simple and low in cost.

Description

technical field [0001] The invention relates to a nonwoven fabric and a manufacturing method thereof, in particular to a nonwoven fabric for making dust-free wiping paper and a manufacturing method thereof. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which is formed by directly using polymer chips, short fibers or filaments to form fibers through airflow or mechanically, and then strengthened by hydroentanglement, needle punching or hot rolling, and finally finished. non-woven fabric. Non-woven fabric is a new type of fiber product with soft, breathable and planar structure. It is widely used because it is environmentally friendly and easy to degrade (if it is placed outdoors and decomposed naturally, its longest life is only 90 days), it is widely used as wiping paper. use. The materials of non-woven fabrics include polyester, polypropylene, nylon, spandex, and acrylic. Most of these materials have poor hydrophilic properties. The wipin...
