Embodiment Construction

[0021] The present invention provides a method for manufacturing non-woven fabric permeable bricks, and the permeable bricks made by the manufacturing method; wherein the manufacturing method can be applied to various types of non-woven fabrics, whether artificial or natural, or even general Various types of nonwovens are commercially available. In other words, the non-woven fabric permeable brick of the present invention can be made of various non-woven fabrics using the manufacturing method of the present invention.

[0022] Generally, the manufacturing process of non-woven fabrics is roughly four steps: fiber forming, web forming, bonding, and coiling. There are different types of non-woven fabrics according to different product requirements. figure 2 It shows the production process of a non-woven fabric; first, various fibers can be placed in the pre-feeder 1 (pre-feeder) for pre-blending (pre-blending), and then the fibers are placed in the opener 2 (opener) to loosen ,...

Abstract

The invention provides a method for making a nonwoven water-permeable brick. The method comprises the following steps: providing a bundled non-woven fabric; coating the bundled nonwoven fabric with a first colloid; cutting the coated bundled nonwoven fabric into a plurality of nonwoven fabric sheets; stacking the coated bundled nonwoven fabric sheets to form a stacked nonwoven layer; bonding the stacked nonwoven layer with a second colloid; extruding the bonded stacked nonwoven layer in order to make the bonded stacked nonwoven layer have a required thickness; and drying the extruded stacked nonwoven layer to form the nonwoven water-permeable brick. The invention also provides the nonwoven water-permeable brick.

Description

technical field [0001] The invention provides a non-woven permeable brick and a manufacturing method thereof. In particular, the permeable brick is made of non-woven fabric, which is not only light in weight, strong but also has good water permeability. Background technique [0002] On general sidewalks or bicycle lanes, in order to increase the appearance and smoothness of the road, bricks are mostly laid on it. Protect the road surface to prevent problems such as potholes. [0003] However, most of the aforementioned bricks are laid with traditional paving bricks, which do not have water permeability and water retention. Once it rains, the rainwater will stay on these bricks and be introduced into public drainage facilities, which will not only cause water resources waste, which in turn creates a burden on public drainage facilities and easily causes flooding in low-lying areas. With the concept of water conservation and environmental protection, permeable bricks have be...
