Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 4, the lightweight moisture-proof non-woven fabric comprises an inner layer 1, an intermediate layer 2 and a base layer 3 which are sequentially arranged, wherein the inner layer 1 and the base layer 3 are respectively arranged at two sides of the intermediate layer 2 and are both in hot-melt bonding connection with the intermediate layer 2, and after hot-melt bonding, the three-layer composite fabric is firmer without affecting the softness and toughness of the fabric.

The inner layer 1 is a polypropylene fiber non-woven layer, the polypropylene fiber is mainly characterized by light weight and the density of the polypropylene fiber is only 0.91g/cm ³ The inner layer 1 is the lightest variety among common chemical fibers, so that the inner layer 1 can achieve the light effect; the polypropylene fiber has high strength and good heat retention property, and is suitable for being used as tent fabric.

One side of the inner layer 1, which is far away from the middle layer 2, is provided with a plurality of moisture absorption strips 4 which are arranged in parallel, the moisture absorption strips 4 are arc-shaped and raised, the bulges of the moisture absorption strips 4 are not obvious, and the highest point of the bulges is about 1mm away from the inner layer 1, so that the hand feeling and the use feeling of the fabric cannot be influenced by the bulges.

As shown in figure 2, the distance between the absorbent strips 4 is 15-20cm, and the distance is larger, so that the number of the absorbent strips 4 can be reduced, the weight of the fabric can be reduced, and the absorbent strips 4 can play a role in absorbing moisture. The absorbent strip 4 is bonded with the inner layer 1, so that the absorbent strip is fixed on the inner layer 1. The moisture absorption strips 4 are made of bamboo fiber needle-punched non-woven strips, the cross sections of the bamboo fibers are deformed in a concave-convex mode, holes which are similar to oval shapes are fully distributed, the bamboo fibers are hollow, capillary effects are strong, moisture can be absorbed instantly, the bamboo fibers have good moisture absorption performance, and the problem that the fabric gets damp can be effectively solved. The bamboo fiber also has certain antibacterial activity, and is not easy to mildew or smell even in a humid environment.

The middle layer 2 is a needle-punched non-woven fabric layer, the middle layer 2 is provided with a plurality of spaced holes 22, and the spaced holes 22 are uniformly arranged at intervals and penetrate through the middle layer 2. The spacing holes 22 can be punched on the pre-needled web by a pattern needling machine to produce a desired appearance effect; or can be formed by a fabric punching device after the fiber web is formed on a common needle machine.

As shown in fig. 3, the spacing holes 22 in the middle layer 2 are distributed in a rectangular array, and the distance between two adjacent spacing holes 22 is less than twice the diameter of the needling space, so that the total area of the spacing holes 22 occupies about half of the area of the whole middle layer 2, and the weight of the fabric can be greatly reduced without affecting the fabric support. The diameter of the spacing holes 22 may be determined according to the production conditions of the machine and is not a definite value.

Non-weaving surface fabric can accurate control surface fabric thickness, the utility model discloses the surface fabric main material of mainly used tent, consequently 2 mm's thickness in intermediate level, nexine 1 is half of 2mm thickness in intermediate level with the thickness of basic unit 3, respectively is 1 mm. The thickness is controlled mainly in order to control the quality of the fabric.

As shown in fig. 4, the intermediate layer 2 includes a plurality of hollow fibers 5, and through holes 52 are provided in the hollow fibers 5 so as to extend in the longitudinal direction of the hollow fibers 5. The presence of the through holes 52 enables a reduction of 20% of the weight of the fiber and the inclusion of a large amount of still air, so that the hollow fiber 5 is lighter in weight and better in warmth than a normal fiber.

The hollow fiber 5 is polyester staple fiber which is formed by adopting an annular hollow spinneret orifice through melt spinning, the polyester staple fiber is more suitable for being used as a needle-punched non-woven material, and the polyester fabric has better crease resistance and shape retention, and has higher strength and elastic recovery capability.

The base layer 3 is a waterproof layer, the waterproof layer comprises a polypropylene fiber non-woven layer and a waterproof film layer, the polypropylene fiber non-woven layer and the middle layer 2 are in hot melt adhesion, the waterproof film layer is arranged on one side, away from the middle layer 2, of the polypropylene fiber non-woven layer, the waterproof film layer is a TPU waterproof film, and the TPU waterproof film has the characteristics of high tension, high tensile force, toughness and ageing resistance and is mainly used for preventing the outside of the fabric from being affected.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
