Abstract

The invention relates to the technical field of non-woven fabrics, and discloses a preparation process of a tensile breathable needle-punched non-woven fabric. The preparation process comprises the following steps: a, a fiber raw material is prepared, and a fiber auxiliary material is prepared; b, primary fiber web forming is conducted, specifically, a plurality of net-shaped main fiber thin layers are superimposed to form a lower-layer main fiber web, primary spray melting is conducted on the upper surface of the lower-layer main fiber web to form a lower spray-melted fiber layer, a pluralityof net-shaped auxiliary fiber thin layers are laid on the upper surface of the lower spray-melted fiber layer, an auxiliary fiber layer is formed on the upper surface of the lower spray-melted fiberlayer, and then composite fiber net is pressed and formed through a pressing roller; c, primary needle punching is conducted; d, secondary fiber web forming is conducted, specifically, secondary spraymelting is conducted on a composite fiber web, a plurality of net-shaped main fiber thin layers are laid on the upper surface of an upper spray-melted fiber layer, and the whole body is pressed through the pressing roller to form a semi-finished non-woven fabric product with the gram weight of 65-100g / m<2>; and e, secondary needle punching is conducted, specifically, after the semi-finished non-woven fabric product is secondarily needle-punched and shaped, a finished non-woven fabric product is manufactured. The non-woven fabric has the beneficial effects of good tensile property, good air permeability and good thermal insulation property.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric manufacturing, in particular to a preparation process for stretch-resistant and air-permeable needle-punched non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers, and are called cloth because of their appearance and certain properties. Non-woven fabrics have many advantages such as moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Non-woven fabrics are simple to manufacture, low in cost, and very widely used widely. There are many preparation processes for non-woven fabrics, such as spunlace process, acupuncture process, hot rolling process, etc. The spunlace process is usually aimed at non-woven fabrics with a small grammage, and acupuncture is generally used for non-woven fabrics with...
