Embodiment 1

[0030] This embodiment discloses an impregnated non-woven fabric and a manufacturing method thereof.

[0031] Wherein, the raw material ratio of the impregnated non-woven fabric is as follows:

[0032] The mass percentage of the raw material of the first fiber is: the proportion of the low melting point fiber accounts for 15%, and the proportion of the polyester fiber accounts for 85%; the mass percentage of the raw material of the second fiber is: the proportion of the low melting point fiber accounts for 85%. 20%, the proportion of the viscose staple fiber accounts for 10%, the proportion of the polyester fiber accounts for 70%, and the concentration of the polyacrylate on the upper surface of the impregnated non-woven fabric is 10%. The concentration of the polyacrylate on the lower surface of the impregnated non-woven fabric is 25%.

[0033] In addition, the first fiber and the second fiber, low melting point fiber, viscose staple fiber and polyester fiber are described a...

Embodiment 2

[0056] This embodiment discloses an impregnated non-woven fabric and a manufacturing method thereof. The difference between this embodiment and embodiment 1 lies in: the ratio of raw materials and the steps (1), (4), (5), (6), (8) and (9) of the manufacturing method.

[0057] Wherein, its raw material mass percentage is as follows:

[0058] The raw material mass percentage of the first fiber is: low melting point fiber accounts for 5% of the first fiber total amount, polyester fiber accounts for 95% of the first fiber total amount; the raw material mass percentage of the second fiber is: the low Melting point fiber accounts for 10% of the second fiber total amount, and the viscose staple fiber accounts for 5% of the second fiber total amount, and 85% of the second fiber total amount of the polyester fiber, and the polyacrylate is impregnated in the The concentration on the upper surface of the impregnated non-woven fabric is 10%, and the concentration of the polyacrylate on t...

Embodiment 3

[0073] This embodiment discloses an impregnated non-woven fabric and a manufacturing method thereof. The difference between this embodiment and embodiment 1 lies in: the ratio of raw materials and the steps (1), (4), (5), (6), (8) and (9) of the manufacturing method.

[0074] Wherein, its raw material mass percentage is as follows:

[0075] The raw material mass percentage of the first fiber is: low melting point fiber accounts for 20% of the first fiber total amount, polyester fiber accounts for 80% of the first fiber total amount; the raw material mass percentage of the second fiber is: the low melting point fiber accounts for 20% of the first fiber total amount; Melting point fiber accounts for 30% of the second fiber total amount, and described viscose staple fiber accounts for 15% of the second fiber total amount, and described polyester fiber accounts for 55% of the second fiber total amount, and described polyacrylate is in the described The concentration on the upper ...

Abstract

The invention relates to the field of non-woven fabrics, and discloses an impregnated non-woven fabric and a manufacturing method thereof, wherein the first fibers include low-melting-point fibers and polyester fibers, and the second fibers include low-melting-point fibers, viscose staple fibers and Polyester fiber, the raw material mass percentage of the first fiber is: low melting point fiber accounts for 5% ~ 20% of the first fiber total amount, polyester fiber accounts for 80% ~ 95% of the first fiber total amount; the second fiber The mass percentage of raw materials is: low melting point fiber accounts for 5%~20% of the total amount of the second fiber, polyester fiber accounts for 80%~95% of the total amount of the second fiber, viscose staple fiber accounts for 5% of the total amount of the second fiber ~15%, the concentration percentage of the polyacrylate is divided into two types: 10% and 25%. In the present invention, the processes of fiber laying, puncturing up and down, heat drying, hot blanching, addition of polyacrylate, drying, and hot blanching are completed. The characteristics of large quantity.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to an impregnated non-woven fabric and a manufacturing method thereof. Background technique [0002] Non-woven fabric, English name: Non Woven, also known as non-woven fabric, is composed of directional or random fibers. Irritation, rich colors, low price, and can be recycled, so in recent years, my country's non-woven fabric industry has continued to develop rapidly, and its total output has ranked second in the world. Emerging fields such as filters, medical textiles, flame retardant Textiles such as textiles, protection, and special composite materials have also shown novel development patterns, especially in the air filter industry, showing a prosperous development scene. [0003] However, due to the lamination process used in the production of the existing non-woven fabrics, the structure of the produced non-woven fabrics is extremely poor, the filterability is low, and the appe...
