Abstract

The present invention relates the field of non-wovens, and discloses an impregnated-type non-woven and a manufacturing method thereof. A first fiber comprises a low melting point fiber and a polyester fiber; and a second fiber comprises a low melting point fiber, a viscose staple fiber and the polyester fiber. The raw materials of the first fiber are as follows: the low-melting fiber accounts for 5% to 20% by mass of the total mass of the first fiber, and the polyester fiber accounts for 80%-95% by mass of the total mass of the first fiber. The raw materials of the second fiber are as follows: the low melting point fiber accounts for 5% to 20% by mass of the total mass of the second fiber, the polyester fiber accounts for 80% to 95% by mass of the total mass the second fiber, and the viscose staple fiber accounts for 5% to 15% by mass of the total mass of the second fiber. The concentration percentage by mass of polyacrylate is divided into two types, 10% and 25%. According to the invention, the impregnated-type non-woven are manufactured by performing the process of first tiling, punching through up and down, hot baking, hot ironing, adding the polyacrylate, drying, and hot ironing to the fibers for the first time. The impregnated-type non-woven has the characteristics of good adsorptivity, high filterability, and a large dust-holding capacity.

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...
