Composite fiber material and preparation method, device and application of material

Abstract

The invention belongs to the field of fiber products with special performance and composite materials, in particular to a composite fiber material and a preparation method, device and application of the material. The composite fiber material comprises a bottom layer and a surface layer, the bottom layer is glued to the surface layer through a gluing part, protruding points which protrude upwards are distributed on the surface layer and comprise arc protruding points, vertical protruding points and natural half protruding points, and the vertical protruding points are provided with one or moreneedle holes. According to the composite fiber material, the 5D stereoscopic effect is achieved, by improving the layer stereoscopic sense, the contact area is further reduced, the dry and comfortableperformance, air permeability and attractiveness are improved, the composite material is applied to diapers, sanitary napkins or other disposable absorption supplies, and the prepared absorption supplies are good in softness and good in air permeability.

Description

technical field [0001] The invention belongs to the field of special performance fiber products and composite materials, and in particular relates to a composite fiber material and its preparation method, device and application. Background technique [0002] In the prior art, the single-layer fiber product has holes and three-dimensional effects, but there are the following deficiencies: 1. The three-dimensional retention of the single-layer fiber product is very poor, especially when it is used to make diapers or sanitary napkins. When used on other materials, it will greatly affect the three-dimensional effect, and will also affect the breathability and dryness: 2. The aesthetics will also be affected. [0003] However, the existing double-layer composite materials on the market are generally made into a 3D three-dimensional layer, and one layer is bonded with glue as a support, but there are the following deficiencies: 1. The glue will close the upper hole that has been p...

[0002] In the prior art, the single-layer fiber product has holes and three-dimensional effects, but there are the following deficiencies: 1. The three-dimensional retention of the single-layer fiber product is very poor, especially when it is used to make diapers or sanitary napkins. When used on other materials, it will greatly affect the three-dimensional effect, and will also affect the breathability and dryness: 2. The aesthetics will also be affected

[0003] However, the existing double-layer composite materials on the market are generally made into a 3D three-dimensional layer, and one layer is bonded with glue as a support, but there are the following deficiencies: 1. The glue will close the upper hole that has been punched during bonding, affecting Permeability and aesthetics; 2. The bond formed after the glue solidifies will reduce the softness; 3. There is still room for improvement in the three-dimensional effect
