Problems solved by technology

[0002] With the continuous development of the sanitary products industry, the changes in materials are changing with each passing day. Ordinary single-layer materials can no longer meet the needs of existing materials for sanitary products. Therefore, we are developing double-layer composite products, which have a three-dimensional appearance. The effect is obvious and the setting effect is good, so it is also called 3D three-dimensional embossing products; Penetration ability is not guaranteed

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings, but it is not intended to limit the protection scope of the present invention.

[0024] Such as Figure 1-3 As shown, a dumbbell-shaped pressure point composite non-woven fabric includes a composite surface layer 1 and a bottom layer 2, the surface layer 1 is a hot-air non-woven fabric, and the bottom layer 2 is a hot-air non-woven fabric. Ultrasonic thermal bonding and embossing through dumbbell-shaped flat points 9, and after ultrasonic thermal bonding between the surface layer 1 and the bottom layer 2, several pearl-shaped bumps 3 are formed, and between the surface layer 1 and the bottom layer 2 through dumbbell-shaped After the flat point 9 is embossed, several dumbbell-shaped shaping points 8 are formed, and there is a dumbbell-shaped shaping point 8 between every four adjacent pearl-shaped swelling points 3 . The length*width of the dumbbell-shaped shap...

Abstract

The invention discloses a dumbbell-shaped pressure-point composite non-woven fabric and a processing device and technology thereof. The non-woven fabric comprises a face layer and a bottom layer whichare compounded; the face layer is a hot-air or anti-attachment non-woven fabric, the bottom layer is a hot-air or anti-attachment non-woven fabric, and the face layer and the bottom layer are subjected to thermal bonding through ultrasonic waves and subjected to dumbbell-shaped flat-point embossing, so that multiple pearl-shaped bump points are formed between the face layer and the bottom layer;the face layer and the bottom layer are subjected to dumbbell-shaped flat-point embossing to form multiple dumbbell-shaped sizing points, and one dumbbell-shaped sizing point is formed among every four adjacent pearl-shaped bump points. According to the non-woven fabric, by adopting a unique dumbbell-shaped structure, the adhesion area is increased, so that the interlayer stripping force of the non-woven fabric is increased; the structure has good anti-reverse-osmosis capacity and permeation capacity, so that the non-woven fabric has a good three-dimensional effect, permeation is quick, back permeation is low, the hand feeling is even, the compounding strength is high, the stripping force is large, and the non-woven fabric has certain significance in the field of application of sanitationsupplies.

Description

technical field [0001] The invention relates to a sanitary product raw material, in particular to a dumbbell-shaped pressure-point composite non-woven fabric and its processing equipment and processing technology. Background technique [0002] With the continuous development of the hygiene products industry, the changes in materials are changing with each passing day. Ordinary single-layer materials can no longer meet the needs of existing materials for hygiene products. Therefore, we are developing double-layer composite products, which have a three-dimensional appearance. The effect is obvious and the setting effect is good, so it is also called 3D three-dimensional embossing products; Permeability cannot be guaranteed. Contents of the invention [0003] In order to solve the defects and deficiencies in the above-mentioned prior art, the present invention provides a unique dumbbell-shaped structure, which increases the adhesion area and increases the interlayer peeling ...
