Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of non-woven material manufacturing, and in particular to a preparation device and method of a fluffy hydroentangled non-woven fabric and a fabric product. BACKGROUND

[0002] Hydroentangled non-woven fabric: through continuous spraying of high-pressure water flow on a fiber web, the fibers are entangled with each other to form a non-woven fabric with certain physical and mechanical properties and appearance. This process mainly uses chemical fibers and cotton fibers as raw materials to produce products with high strength, good air permeability, drape, softness and water absorption. Because it does not use adhesives and does not pollute the environment, it is called "green product". The common hydroentangled non-woven fabric has a grammage range of 30-250g / m 2 .

[0003] Makeup cotton process, grammage: the general process of making makeup cotton is: raw material winding on the machine-automatic conveying-embossing-rolling cutting-arranging out of material-waste winding-automatic counting-product. Due to the material and shape, there may be slight differences in the process, but they are basically the same.

[0004] However, the surface layer and core layer of the existing makeup cotton are made of the same material, and the core layer or the surface layer cannot be changed in material. If high-grammage makeup cotton is needed, multiple carding machines are required, which not only wastes equipment but also consumes high energy and has low production efficiency.

[0005] The common medical dressing has a grammage range of about 300g / m 2 or less, and the grammage range is different for different purposes. For dressing pads or water-absorbing dressings, a higher grammage is required, and it may be even higher according to the needs. However, the common hydroentangled carded web has a grammage range of 30g / m 2 -250g / m 2 ; medical dressings sometimes need fibers with special functions, but the prices of such fibers are relatively high or they cannot directly contact the skin, so other types of fibers need to be added to the surface layer of the fibers.

[0006] After being opened by the edge strip opener, some fibers have a large strength loss and low strength, which are not suitable for carding and can only be treated as waste fibers. The use of functional fibers in the entire hydroentangled product will increase the cost, and some functional fibers cannot be directly used on the surface, cannot directly contact the skin, or cannot directly act on the contact surface fibers.

[0007] The information disclosed in this BACKGROUND section is only intended to increase an understanding of the general context of the application and is not to be taken in any way as an acknowledgment or any form of suggestion that this information forms prior art that is already known in the art.

[0051] Example three

[0052] The third embodiment of the present application provides a fluffy hydroentangled nonwoven fabric product, which is prepared by the fluffy hydroentangled nonwoven fabric preparation device or by the fluffy hydroentangled nonwoven fabric preparation method as described above.

[0053] In actual application, the fluffy hydroentangled nonwoven fabric preparation device, method and fabric product of the present application, the waste (waste hydroentangled fabric strip 25) is pulled into the opening area at a uniform speed by the roller 22 of the leftover material opening machine 13, is opened into fibers of 20-30 mm in length by the opening roller 23, is then conveyed to the cotton box 16 by the cotton conveying fan 15 and the second cotton conveying pipeline 18 through the first cotton conveying pipeline 14, the fibers are uniformly distributed into a cotton layer inside the cotton box 16, the rotating speed of the cotton conveying fan 15 can be automatically adjusted according to the set pressure inside the cotton box 16 to ensure the density of the cotton layer. After the cotton layer is compacted by the cotton conveying fan 15, the airflow is discharged from the exhaust plate 21, the compacted cotton layer reaches the cotton uniformizing fan outlet, the cotton uniformizing fan is designed with high air pressure and low air volume, the air outlet 24 is opened by 5-12 mm, the air outlet 24 is designed with a flow guide, the airflow passes through the air outlet 24 to mix the fibers and then smoothly enters the carding curtain 17, the fibers are extruded by the carding curtain 17 to form a uniform cotton layer (regenerated fiber cotton 5) which enters the next process (the conveying mechanism 1), and the fiber scraps and impurities are discharged into the dust filtering system through the air outlet 20.

[0054] The cotton uniformizing fan has the following functions: the air outlet 24 of the fan is designed with a small outlet and high air pressure, the outlet is designed in a V-shaped flat opening manner, which can uniformly diffuse the cotton layer to both sides and convey the cotton layer to the cotton conveying curtain.

[0055] The formed cotton layer and the fiber web formed by the first cotton net 3 and the second cotton net 7 form a fiber layer with a “sandwich” structure which enters the hydroentangling system (hydroentangling mechanism 8). The upper, middle and lower three layers of fibers form a fluffy hydroentangled nonwoven material in a “tight-loose-tight” state under the hydroentangling system. The weight of the upper and lower two layers of nets ranges from 20 g / m 2 -50 g / m 2 , and the weight of the middle sandwiched fiber layer ranges from 100 g / m 2 -300 g / m 2 .

[0056] The selected waste hydroentangled fabric strip 25 is any openable hydroentangled fabric, and the formed fibers can directly enter the cotton box 16 regardless of whether they can be carded again.

[0058] The formed water-jet nonwoven material has super high weight, the upper and lower edges are tightly entangled, and the middle is loosely entangled, so that the formed water-jet nonwoven material is not only fluffy, has strong moisture absorption capacity, and high liquid carrying rate; and by adding waste functional fibers, or some functional fibers cannot be used on the surface, by being placed in the middle fiber cotton layer, the corresponding special functions of the fibers can be realized, the production cost is reduced, and the fiber waste material can be reused. The product can be applied to wiping, oil absorption, makeup removal cotton, medical dressing, sanitary products and the like.

[0059] The present application adopts waste water-jet fabric to pass through an opening cotton device into the middle of two layers of fiber web to form a fluffy water-jet nonwoven material with a "sandwich" structure of super high weight and "upper and lower tightly entangled, middle loosely entangled". The waste water-jet fabric used in the present application is water-jet nonwoven fabric cut from conventional products, waste fabric samples, and raw product which cannot be used or sold as normal products. The waste water-jet nonwoven fabric used can be composed of conventional viscose and polyester fibers; can be composed of fibers with special functions (biodegradable fibers, high-emissivity far-infrared fibers, negative ion fibers, antibacterial and deodorant fibers, flame-retardant fibers, and fragrance fibers); can be composed of fibers with different fineness (0.5D-2.0D); can be composed of fibers with different lengths (20mm-30mm); can be composed of fibers opened from water-jet fabric of different colors; single component water-jet fabric can be selected, or multiple components can be mixed. The formed middle fiber layer has different styles, and the fiber composition of the formed water-jet nonwoven fabric is also different.

[0060] In summary, the preparation device, method and fabric product of the fluffy water-jet nonwoven fabric of the present application utilize waste water-jet nonwoven fabric to form a regenerated fiber cotton layer, which is placed in the middle of two layers of cotton web to form a fluffy water-jet nonwoven fabric with super high weight and different styles; the waste water-jet nonwoven fabric is fully utilized, and functional fibers can be added to prepare water-jet fabric; a small amount of or waste functional water-jet fabric can be used to prepare water-jet nonwoven fabric with the function; not only waste is recycled, but also the cotton layer is directly formed without opening and carding, so that the production efficiency is improved and the cost is reduced.
