Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a super-fiber flexible hot-air nonwoven fabric. Background Technology

[0002] Hot air nonwoven fabric belongs to the category of hot air bonded thermal roll and hot air nonwoven fabric. Hot air nonwoven fabric is produced by bonding the fibers together after they are combed together using hot air from a drying device that penetrates the fiber web.

[0003] The weaving and fiber combing of hot-air nonwoven fabrics are particularly critical, as the quality of the fibers affects the quality and comfort of the nonwoven fabric. The application of microfiber textile technology is often combined with mechanical weaving, but this can result in the mixing of various microfibers in complex yarns. The thick weaving layers affect the functional quality of each microfiber yarn, which can easily lead to complicated processing of hot-air nonwoven fabrics, a wide variety of repair and yarn replacement methods, and difficulty in repairing microfibers by tangling yarns. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a microfiber elastic hot-air nonwoven fabric. The weaving and fiber combing of hot-air nonwoven fabrics are particularly critical, as fiber quality significantly impacts the fabric's usability and comfort. While microfiber textile technology is often integrated with mechanical weaving, this results in complex yarns with multiple microfibers mixed together. Thick weaving layers affect the functional quality of each microfiber yarn, easily leading to complex processing techniques, numerous repair and yarn replacement options, and difficulties in repairing loose microfibers.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a super-fiber flexible hot-air nonwoven fabric, comprising an outer protective fabric layer, a hot-air cotton filter layer, a meltblown fabric layer, and an inner nonwoven fabric layer, wherein the outer protective fabric layer is thermally bonded to the top surface of the hot-air cotton filter layer, the top surface of the meltblown fabric layer is thermally bonded to the hot-air cotton filter layer, the meltblown fabric layer is thermally bonded to the top surface of the inner nonwoven fabric layer, and the outer protective fabric layer, the hot-air cotton filter layer, the meltblown fabric layer, and the inner nonwoven fabric layer are thermally bonded together as a single unit.

[0006] Preferably, the outer protective fabric layer is provided with microfiber soft yarn and honeycomb yarn surface, and the microfiber soft yarn and honeycomb yarn surface are intertwined together.

[0007] Hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded nonwoven fabrics. The honeycomb surface is a tension mesh fabric with a special shape, which is convenient to be made by combining hot-bonded microfiber yarns.

[0008] Preferably, the hot air cotton filter layer has a cotton core yarn surface, and the microfiber soft yarn is intertwined with the cotton core yarn surface; the meltblown fabric layer has a double yarn surface, and the microfiber soft yarn is intertwined with the double yarn surface.

[0009] Hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded nonwoven fabrics. The cotton core yarn surface and the double yarn surface are special shapes of single or double strands of yarn tension mesh fabric, which are convenient to be combined with hot-bonded microfiber yarns.

[0010] Preferably, the inner nonwoven fabric layer has a cross-shaped surface, and the microfiber soft yarn is intertwined with the cross-shaped surface.

[0011] Hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded nonwoven fabrics. The cross-line surface is a special shape with transverse and longitudinal extension tension mesh fabric, which is convenient to be made by combining hot-bonded microfiber yarns.

[0012] Preferably, the microfiber soft yarn has a densely woven composite layer, which is thermally bonded to the honeycomb yarn surface.

[0013] By using a densely woven composite layer with an inner layer of ultra-fine yarn and an outer layer of interwoven yarn mesh, a composite high-density fine-stitch yarn layer structure is formed, achieving the elastic quality of soft composite yarn with extremely high extensibility. This allows for the use of the same ultra-fine yarn in the four layers: outer protective fabric, hot air cotton filter layer, meltblown fabric layer, and inner non-woven fabric layer. It also facilitates easy removal and replacement of single or double strands of the wound yarn, improving the ease of repair of hot air non-woven fabric.

[0014] This invention provides a microfiber elastic hot-air nonwoven fabric with the following beneficial effects:

[0015] This type of ultra-fine, elastic hot-air nonwoven fabric is produced by laying out four layers sequentially from top to bottom: the outer protective layer with honeycomb yarns, the hot-air cotton filter layer with cotton core yarns, the meltblown fabric layer with double yarns, and the inner nonwoven fabric layer with cross-shaped yarns. After pre-weaving the ultra-fine yarns into a dense composite layer to create four layers of inner-wound yarn mesh, a four-stage hot-air bonding process is performed. This allows the fibers to be combed, and the hot air penetrates the fiber mesh, causing it to be heated and bonded to form the nonwoven fabric. When the hot-air nonwoven fabric is damaged, the ultra-fine yarns can be pulled out, re-drawn, and re-woven to comb the fiber layers, facilitating secondary hot-air bonding and repair. This makes the repair of the hot-air nonwoven fabric simple and convenient. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model provides a super-fiber flexible hot air nonwoven fabric, including an outer protective fabric layer 1, a hot air cotton filter layer 2, a meltblown fabric layer 3, and an inner nonwoven fabric layer 4. The outer protective fabric layer 1 is thermally bonded to the top surface of the hot air cotton filter layer 2. The top surface of the meltblown fabric layer 3 is thermally bonded to the hot air cotton filter layer 2. The meltblown fabric layer 3 is thermally bonded to the top surface of the inner nonwoven fabric layer 4. The outer protective fabric layer 1, the hot air cotton filter layer 2, the meltblown fabric layer 3, and the inner nonwoven fabric layer 4 are thermally bonded together as a single unit.

[0024] Because the weaving and fiber combing of hot-air nonwoven fabrics are particularly critical, the quality of the fibers affects the quality and comfort of the nonwoven fabric. The application of microfiber textile technology is often combined with mechanical weaving. However, this can result in the mixing of various microfibers in complex yarns. The thick weaving layers affect the functional quality of each microfiber yarn, which can easily lead to complicated processing of hot-air nonwoven fabrics, a wide variety of repair and yarn replacement methods, and difficulties in repairing microfibers by tangling yarns.

[0025] The outer protective fabric layer 1 is provided with microfiber soft yarn 11 and honeycomb yarn surface 12, and the microfiber soft yarn 11 and honeycomb yarn surface 12 are intertwined together.

[0026] It should be noted that hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded nonwoven fabric. The honeycomb surface 12 is a tension mesh fabric with a special shape, which is convenient to be made by combining hot-bonded microfiber yarns.

[0027] The hot air cotton filter layer 2 is provided with a cotton core yarn surface 21, and the microfiber soft yarn 11 is intertwined with the cotton core yarn surface 21. The meltblown fabric layer 3 is provided with a double yarn surface 31, and the microfiber soft yarn 11 is intertwined with the double yarn surface 31.

[0028] It should be noted that the hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded and hot air nonwoven fabrics. The cotton core yarn surface 21 and the double yarn surface 31 are single or double strands of yarn tension mesh fabric with special shapes, which are convenient to be made by combining hot-bonded microfiber yarns.

[0029] The cotton core yarn surface 21 is a mesh fabric surface layer produced by the cotton core yarn to simulate the filter layer of the non-woven fabric with hollow thick yarn. The hot rolling of the cotton yarn hot air bonding needs to ensure a certain level of safety and fire resistance.

[0030] The double yarn surface 31 is a mesh fabric surface layer with high density bonding of upper and lower layers of interwoven yarns. It is set up to prevent high-strength penetrating hot air from flowing through the middle layer. During the hot rolling process of hot air bonding in the fabric surface, the upper and lower layers are close to different fabric surfaces to adjust the gaps and form the gaps of the non-woven fabric, which is then drawn out, combed, and woven.

[0031] The inner nonwoven fabric layer 4 is provided with a cross-shaped surface 41, and the microfiber soft yarn 11 is intertwined with the cross-shaped surface 41.

[0032] It should be noted that hot air nonwoven fabric belongs to the category of hot air bonded thermally bonded and hot air nonwoven fabric. The cross-line surface 41 is a special shape with transverse and longitudinal extension tension mesh fabric, which is convenient to be made by combining hot-bonded microfiber yarns.

[0033] The microfiber soft yarn 11 is provided with a densely woven composite layer 111, which is thermally bonded to the honeycomb yarn surface 12.

[0034] It should be noted that the composite layer 111, which consists of an inner layer of ultra-fine yarn and an outer layer of interwoven yarn mesh, forms a composite high-density fine-stitch yarn layer structure. This achieves the elastic quality of the soft composite yarn, with extremely high extensibility. It facilitates the use of the same ultra-fine yarn in the four layers: outer protective fabric layer 1, hot air cotton filter layer 2, meltblown fabric layer 3, and inner non-woven fabric layer 4. It also allows for easy removal and replacement of single or double strands of the wound yarn, improving the ease of repair of the hot air non-woven fabric.

[0035] Workers lay out the outer protective fabric layer 1 (honeycomb yarn surface 12), the hot air cotton filter layer 2 (cotton core yarn surface 21), the meltblown fabric layer 3 (double yarn surface 31), and the inner nonwoven fabric layer 4 (cross yarn surface 41) sequentially from top to bottom. After the densely woven composite layer 111 of the microfiber soft yarn 11 is pre-hooked and interwoven to form a four-layer inner winding yarn mesh, the nonwoven fabric is formed by four composite hot air bonding operations. After the fibers are combed, the hot air penetrates the fiber mesh and heats it to bond the nonwoven fabric. When the hot air nonwoven fabric is damaged, the microfiber soft yarn 11 can hook out the broken yarns, re-draw and interweave the fiber layers, and facilitate the hot air bonding repair of the secondary hot air nonwoven fabric, making the repair of the hot air nonwoven fabric simple and convenient.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
