Problems solved by technology

[0010] The purpose of the present invention is to solve the problem that the existing air-through nonwoven fabric is easy to fluff, aiming at the deficiencies of the existing technology, and to provide a geometric shape that combines points, lines and surfaces on the surface of the nonwoven fabric, and the fiber structure of the fabric surface is bonded. A new type of non-woven fabric with good molding, soft hand feeling, standard thickness and less hairiness during use

Embodiment 1

[0044] Method Example 1: Hot air forming of nonwoven fabric, that is, the fiber web oriented in the running direction of the equipment is first shaped by a hot air blower at a temperature of 120 ° C and a wind pressure of 2000 Pa, and then the hot air formed nonwoven fabric is passed through a belt with engraved The hot rolling mill of the engraved roller, the temperature of the engraved roller is at 150 ℃, the total pressure of the roll web is processed under the condition of 10MPa to form the nonwoven fabric in the present invention, and the hardness of the lower engraved roller is 95HD.

Embodiment 2

[0045] Method Example 2: Hot air forming of nonwoven fabric, that is, the fiber web oriented in the running direction of the equipment is first shaped by a hot air blower at a temperature of 140°C and a wind pressure of 500Pa, and then the hot air formed nonwoven fabric is passed through a belt with engraved The hot rolling mill of the engraved roller, the temperature of the engraved roller is at 100°C, the total pressure of the roll web is processed under the condition of 2MPa to form the nonwoven fabric in the present invention, and the hardness of the lower engraved roller is 60HD.

Embodiment 3

[0046] Method Example 3: Hot air forming of nonwoven fabric, that is, the fiber web oriented in the running direction of the equipment is first shaped by a hot air blower at a temperature of 130 ° C and a wind pressure of 1000 Pa, and then the hot air formed nonwoven fabric is passed through a belt with engraved The hot rolling mill of the engraved roller, the temperature of the engraved roller is at 130 ℃, the total pressure of the roll web is processed under the condition of 5MPa to form the nonwoven fabric in the present invention, and the hardness of the lower engraved roller is 70HD.

Abstract

The invention discloses a novel nonwoven fabric, which is a flexible nonwoven fabric made by hot air. The surface of the fabric consists of hair fixing areas which are connected, the hair fixing areas are formed by flexible convex parts and concave parts arranged in matrixes, and the concave parts are positioned on the peripheries of the flexible convex parts and enclose the flexible convex parts; and the matrix concave parts account for 5 to 25 percent of the total area of the nonwoven fabric. Based on a hot air nonwoven fabric process, post processing and finishing are performed, the pattern shape can be designed and changed according to the requirements of customers and market needs, the feathers on the surface of the hot air nonwoven fabric are reduced considerably and the nonwoven fabric offers a convex-concave feel. Thus, the contact area between the surface fabric and the human body is reduced, and the human body feels more comfortable when the fabric is used.

Description

technical field [0001] The invention relates to a new type of non-woven fabric, in particular to a new type of non-woven fabric used in personal hygiene care products. Background technique [0002] Thermally bonded nonwovens are widely used in women's hygiene products and baby diapers, usually on the top layer or second layer, which can quickly absorb body fluids (menstrual fluid, urine) and guide them as evenly as possible into the underlying layer The absorbent core, in this way, both keeps the skin dry and prevents lateral leakage of body fluids. [0003] Air-through nonwoven fabric is a kind of thermal bonding process. It is widely used in personal hygiene care products because it feels soft and fluffy and can make users feel comfortable. The hot-air nonwoven fabric adopts bi-component fibers with a side-by-side structure or a sheath-core structure. After being carded into a web, the composite fibers are heated by hot air. After the PE in the composite fibers is melted,...
