Problems solved by technology

[0002] At present, the traditional non-woven fabrics for the midsole of shoes are polyester non-woven fabrics, which have poor hygroscopicity. During people's wearing and exercising, the heat and sweat generated by the feet are discharged through the skin and socks and conducted to the inner surface of the shoes. The moisture in the socks cannot be discharged in time, causing the socks to stick tightly to the skin of the feet, causing a sticky and uncomfortable feeling

Embodiment 1

[0028] Embodiment 1, preparation functional sewing non-woven fabric

[0029] (1) take by weighing the nylon fiber of 50 mass parts, the hemp fiber of 30 mass parts and the polypropylene fiber of 20 mass parts as the compound material of preparing hydrophobic layer I;

[0030] Take by weighing the nylon fiber of 40 mass parts, the hemp fiber of 40 mass parts and the polypropylene fiber of 15 mass parts as the compound material of preparing hydrophilic layer;

[0031] Weigh 50 parts by mass of nylon fiber, 30 parts by mass of hemp fiber and 20 parts by mass of polypropylene fiber as a mixture for preparing the hydrophobic layer II.

[0032] The fibers weighed above are opened and carded to obtain a lap, and the lap is needled and combed to obtain a hydrophobic fiber web I, a hydrophilic fiber web and a hydrophobic fiber web II. Lay the above-mentioned hydrophobic fiber net I, hydrophilic fiber net and hydrophobic fiber net II, and obtain a non-woven fabric in which the hydropho...

Abstract

The invention discloses functional stitch-bonded non-woven fabric and a preparation method thereof. The functional stitch-bonded non-woven fabric comprises a hydrophobic layer I, a hydrophilic layer and a hydrophobic layer II which are stacked sequentially together, wherein all of the hydrophobic layer I, the hydrophilic layer and the hydrophobic layer II are made of hydrophobic fibers, hydrophilic fibers and hot-melt bonding fibers. The stitch-bonded non-woven fabric has function gradients comprising intensity gradients, moisture absorption gradients and antibacterial gradients and has the effects of breathability, high strength, wear resistance, tear resistance, moisture absorption, fast drying and bacterial resistance. The provided stitch-bonded non-woven fabric has a one-way moisture conducting property and can be used for manufacturing an insole of a shoe, and the comfort degree of feet is improved. Ramie-polyester blended materials are selected, the non-woven fabric has light and soft texture, high strength and good one-way moisture conducting effect and can effectively absorb moisture, moisture loss is avoided, a hydrophobic surface contacted with skin of feet is kept dry, and more comfortable feelings are brought to users using the one-way moisture-conducting product.

Description

technical field [0001] The invention relates to a functional stitch-bonded non-woven fabric and a preparation method thereof, belonging to the field of non-woven fabrics. Background technique [0002] At present, the traditional non-woven fabrics for the midsole of shoes are polyester non-woven fabrics, which have poor hygroscopicity. During people's wearing and exercising, the heat and sweat generated by the feet are discharged through the skin and socks and conducted to the inner surface of the shoes. The moisture in the socks cannot be discharged in time, causing the socks to stick tightly to the skin of the feet and cause a sticky and uncomfortable feeling. Therefore, it is necessary to provide a functional non-woven fabric for preparing the midsole of shoes, which can improve the comfort of the feet. Contents of the invention [0003] The purpose of the present invention is to provide a functional stitch-bonded non-woven fabric and its preparation method. The stitch-...
