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 high-strength geotechnical cloth and a manufacturing method thereof. The method comprises the following steps of opening of non-woven production equipment, carding, cluttering, lapping, needling, heat setting and finished product winding. A far infrared heat shaping method is used for handling residual stress generated in the procedures of opening, carding into nets, cluttering, lapping, needling and solidifying and accumulated in fibers and in the geotechnical cloth, the connection strength between the fibers is improved, and the physical and mechanical properties of the fibers are improved, so that the overall size stability and mechanical strength (tensile strength, tearing strength and burst strength) of the geotechnical cloth are improved; moreover, the technology is simple, practical and convenient to use and popularize.

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....
