Problems solved by technology

SAP particles are distributed all around the fabric, which not only costs high, but also affects air permeability and soft comfort
The main reason is that it is limited by the current production technology. The fabric manufacturing process usually includes compounding, online cutting, folding and packing, and online cutting. It is technically difficult to arrange SAP around the fabric.

Embodiment 1

[0054] An absorbent hygienic fabric that saves material, the conventional fabric manufacturing process is to produce large rolls and then cut small rolls. Therefore, it is the quickest way to increase the non-SAP particle layer on both sides of the fabric, such as image 3 As shown, 311 is the area where SAP particles are distributed, and 111 is the area where SAP particles are not distributed. There is no SAP particle layer on the left and right sides, and SAP particles are distributed or spaced in the middle area according to the product design. Both the first layer and the second layer on the left and right sides are coated with viscous glue, so that the first layer and the second layer are compounded through the viscous glue, which will effectively prevent SAP particles from leaking from both sides after compounding.

Embodiment 2

[0056] Such as Figure 4 As shown, 312 is the area where SAP particles are distributed, and 112 is the area where SAP particles are not distributed. There is no SAP particle layer at the front and rear positions, and SAP particles are distributed or spaced in the middle area according to the product design. Both the first layer and the second layer on the front and rear sides are coated with viscous glue, so that the first layer and the second layer are compounded by viscous glue, which will effectively prevent SAP particles from leaking from the front and rear sides after compounding. This design is convenient for connection and alignment during the production of sanitary products.

Embodiment 3

[0058] Such as Figure 5 As shown, 313 is the area where SAP particles are distributed, and 113 is the area where SAP particles are not distributed. There is no SAP particle layer at the front and rear positions and on the left and right sides, and SAP particles are distributed or spaced according to the product design in the middle area. In the area without SAP particle layer around, the first layer and the second layer are compounded by viscous glue, which will effectively prevent SAP particles from leaking from the front and rear sides after compounding. This structural design combines the advantages of Embodiment 1 and Embodiment 2.

Abstract

The invention discloses a material-saving water-absorbing sanitary fabric as well as a production device and use method thereof. The material-saving water-absorbing sanitary fabric comprises a top layer, a first water-absorbing layer, a middle layer, a second water-absorbing layer and a bottom layer which are arranged in sequence, and is characterized in that water-absorbing particles are arrangedat the position, close to the center of the breadth of the fabric, of the first water-absorbing layer; a first non-water-absorbing-particle area is arranged in the range of 10 mm to 50 mm close to the edge of the breadth of the fabric, of the first water-absorbing layer; and the fabric further comprises bonding layers which are located between the top layer and the first water-absorbing layer andbetween the bottom layer and the second water-absorbing layer. According to the invention, the problems that an existing product is poor in breathability and high in absorbing particle consumption are solved, and the breathability, the softness, the comfort and the low-cost performance can be improved to the maximum extent.

Description

technical field [0001] The invention relates to a water-absorbing fabric or a breathable fabric, in particular to a material-saving water-absorbing sanitary fabric, a production device and a use method thereof. Background technique [0002] In the field of hygiene products, the currently known fabrics are multi-layer structures, from top to bottom are top layer, spray layer, particle SAP layer, non-woven absorbent layer, particle SAP layer, spray layer and bottom layer structure, or this The seven-layer structure reduces the particle SAP layer and / or non-woven absorbent layer in it. [0003] However, most of the fabrics are surrounded by SAP particles. SAP particles are distributed all around the fabric, which not only has high cost, but also affects air permeability and soft comfort. The main reason is that it is limited by the current production technology. The fabric manufacturing process usually includes compounding, online cutting, folding and packing, and online cutt...
