Example one

The embodiment discloses a composite non-woven fabric, as shown in fig. 1-3, the composite water-absorbing non-woven fabric is a multi-layer composite structure, and comprises a first surface layer 1, a second surface layer 2 and a middle interlayer 3, wherein both the first surface layer 1 and the second surface layer 2 can be made of non-woven fabric materials, and the composite water-absorbing non-woven fabric has good air permeability and water absorption effects.

The first surface layer 1 and the second surface layer 2 are connected with each other through a plurality of connecting points 4, the connecting points 4 are in a dotted dispersed state, and the first surface layer 1 and the second surface layer 2 are connected with each other to form a hollow interlayer 3 structure. The interlayer 3 structure is filled with floccules, and the floccules can support between the first surface layer 1 and the second surface layer 2, so that a certain space of an air layer can be formed between the two; and the floccules are also in a fluffy and soft state, and have good air permeability effect and water absorption effect.

In order to maintain the structural uniformity between the first surface layer 1 and the second surface layer 2, the connection points 4 between the two layers can be uniformly distributed. Evenly distributed's tie point 4 can become the area state of a plurality of fritters with the first unit separation of atress, can increase the intensity between the fabric of both sides, and at the in-process of atress, can transmit each other between the two-layer surface course, bears jointly. And the surface layer I1 and the surface layer II 2 at the position of the connecting point 4 are mutually bonded, and can be bonded by a bonding agent or fused and bonded by adopting a hot-pressing mode, so that the surface layer I1 and the surface layer II 2 can be mutually connected to form a composite whole.

In particular, at the location of the bonded connection points 4, recesses 41 are formed towards the middle, which can be shaped by means of a suitable press piece at the connection points 4. The depressions 41 on the surface of the fabric can form a concave-convex structure on the surface, and can also increase the surface touch of the fabric surface.

The connection points 4 are arranged on the surface of the fabric to form row-shaped connection parts, each connection part is distributed in a strip shape with equal distance and parallel arrangement, strip-shaped gaps 5 are formed between adjacent connection parts, and the floccules are positioned in the strip-shaped gaps 5. In the process of processing and forming, the first surface layer 1 and the second surface layer 2 can be gradually bonded and compounded, and in the bonding process, the floccules are fed between the first surface layer 1 and the second surface layer 2 to realize filling of the floccules.

The connecting points 4 distributed in a dotted manner can avoid forming continuous strip-shaped bonding in the fabric, the situation that the communication between the adjacent strip-shaped gaps 5 is easier to realize is avoided, the gas in the fabric can circulate, and the liquid can normally permeate.

As shown in fig. 1 and 2, the connection points 4 in each row of the connection parts are uniformly distributed at intervals, and the connection points 4 in adjacent rows of the connection parts are distributed in a staggered manner, so that relatively long intervals can be formed between the connection points 4, and a relatively loose state can be formed in the fabric.

In particular, the flock is distributed in the form of a strip, forming a number of flock strips 6, the flock strips 6 being filled along strip gaps 5. In the fabric, the width of each group of strip-shaped gaps 5 is 5-8cm, the width of the flocculent strips 6 is 1/3-2/3 of the strip-shaped gaps 5, and the flocculent strips 6 have certain accommodating spaces in the strip-shaped gaps 5, so that the flocculent strips 6 can shrink and are fluffy, and the loose and smooth state of the fabric is formed.

This flocculent strip 6 includes a plurality of flocculent fibre 61, and flocculent fibre 61 is the tensile deformation silk of DTY, and the tensile deformation silk of DTY presents fluffy state under the lax state, forms loose structure, and the inside absorption of multiplicable cloth and water storage effect for the fabric has good effect of absorbing water. The side-by-side flocked fibers 61 can also increase the tensile strength of the nonwoven fabric in the longitudinal direction, thereby improving the strength of the entire fabric.

Example two

The present embodiment discloses a nonwoven fabric with good elasticity, which is described with reference to fig. 5 on the basis of the first embodiment; the flocculent strip 6 in the non-woven fabric adopts the state that the flocculent fibers 61 and the elastic yarns 62 are combined with each other, a plurality of elastic yarns 62 are arranged in the flocculent strip 6, the elastic yarns 62 are spandex yarns and are arranged side by side with the flocculent fibers 61, and the flocculent fibers 61 and the elastic yarns 62 form a bundle-shaped structure, as in the state of fig. 4, so that the elastic contraction effect of the whole flocculent strip 6 can be increased.

The flocculent strips 6 are laid between the first surface layer 1 and the second surface layer 2, the flocculent strips 6 are in a stretching state, and when the first surface layer 1 and the second surface layer 2 are compounded, the flocculent strips 6 are bonded with the first surface layer 1 and the second surface layer 2 in a dotted manner to form bonding points, and are arranged along the length direction of the flocculent strips 6. The flocculent fibers 61 and the elastic yarns 62 are bonded with each other at bonding points and are simultaneously bonded with the first surface layer 1 and the second surface layer 2 at two sides, so that the whole flocculent strip 6, the first surface layer 1 and the second surface layer 2 form an integral structure. After the processing is finished, the fabric returns to a relaxed state, the length of the flocculent strips 6 is recovered again, and the surfaces of the first surface layer 1 and the second surface layer 2 are slightly wrinkled. The surface fabric of fold state can increase local effect of absorbing water to flocculent strip 6 after the shrink also presents the state of department flocculent, can more adapt to the cloth and use at the operational environment that absorbs water.

EXAMPLE III

The embodiment discloses a non-woven fabric with a waterproof effect, which is further designed on the basis of the first embodiment; in the cloth, the first surface layer 1 and the second surface layer 2 are both non-woven fabrics. And a waterproof membrane is formed on the side of the surface layer I1 opposite to the surface layer II 2, and the waterproof membrane can be processed into a membrane structure by adopting waterproof paint or a composite film. And the surface of the second surface layer 2 is provided with through holes which are uniformly distributed, so that the side of the second surface layer 2 is more permeable to water and water.

The waterproof membrane makes the outer surface of surface fabric one have water-proof effects for the cloth can be waterproof in the one deck, and the opposite side absorbs water, and the state of cloth opposite side can not influenced to its absorptive moisture, forms the effect of blocking.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
