Embodiment Construction

[0013] In order to further understand the contents of the present invention, the present invention will be described in detail in conjunction with examples. It should be understood that the examples are only for explaining the present invention and not for limiting it.

[0014] This embodiment provides a high-strength geotextile and its manufacturing method, including the following steps: opening of non-woven production equipment; carding; messing; laying; needle punching;

[0015] In this embodiment, the non-woven production equipment is any one of a non-woven bag making machine, a non-woven slitting machine or a needle punching machine.

[0016] In this embodiment, the carding machine combs the small cotton bundles prepared by opening and mixing into a thin web composed of single fibers.

[0017] In this embodiment, the disorder is that the short fibers are intertwined with each other.

[0018] In this embodiment, the web laying method is standardized entanglement.

Abstract

The invention relates to the technical field of textiles, in particular to a high-strength geotextile and a manufacturing method thereof, comprising the following steps: opening of non-woven production equipment; around. Through the far-infrared heating and shaping method, through the residual stress accumulated in the fibers and geotextiles generated in the processes of opening, carding, messing, laying, and needle-punching consolidation, the interlocking strength between fibers can be improved, and the geotextile can be improved and improved. Its physical and mechanical properties, thereby improving the overall dimensional stability and mechanical strength (tensile strength, tear strength, burst strength) of the geotextile; and the process is simple, practical, and easy to promote and use.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a high-strength geotextile and a manufacturing method thereof. Background technique [0002] Geotextiles are textiles used in civil engineering. In the initial stage of application, geotextiles are mainly woven and woven geotextiles. With the continuous development of non-woven technology, due to the unique structure and excellent characteristics of non-woven fabrics, it has been rapidly developed and applied in the field of engineering. Among them, non-woven geotextiles mainly composed of short-fiber needle-punched non-woven fabrics are the current geotextiles. The main varieties, this type of product is one of the most widely used nonwoven geotextiles. Compared with woven and woven geotextiles, non-woven geotextiles have higher production efficiency, cheaper prices, good performance, and are especially easy to process into wide-width products, so they are developing rapidly....
