Detailed Description
In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step, based on the given embodiments, fall within the scope of protection of the present application.
In the description of the present application, it is to be understood that the terms "upper", "lower", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present application.
In the description of the present application, the terms "first", "second", and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.
Example one
This embodiment will be described in detail with reference to fig. 1. The embodiment relates to a waterproof glue-spraying type down-like cotton, which comprises a microporous membrane 1, a superfine fiber layer 2, a hot melt adhesive net membrane 3 and a base layer 4.
The superfine fiber layer 2 is formed by superfine fibers which are carded into a net and are bonded by glue spraying. The microporous membrane 1 is compounded on one side of the superfine fiber layer 2, and the superfine fiber layer 2 is bonded with the base layer 4 through the hot melt adhesive net film 3. The superfine fiber used in the superfine fiber layer 2 is polyester superfine fiber or nylon superfine fiber. The superfine fiber has the advantage of providing good heat preservation and warm keeping effects under the condition of thinner thickness. The microfiber layer 2 is cross-lapped in this embodiment.
Specifically, the material of the hot melt adhesive net film 3 is PA, PES, EVA, PI, or TPU, and in this embodiment, TPU is selected.
Further, the base layer 4 is a blended fabric, a pure cotton fabric or a PLA fabric, and further, in this embodiment, the base layer is a blended fabric, specifically, a polyester-cotton blended fabric.
Further, the microporous membrane 1 used was a PTFE microporous membrane, a PUR microporous membrane, a TPU microporous membrane, or a PU microporous membrane, and in this example, a PTFE microporous membrane was selected. The thickness of the microporous membrane 1 is 2-3 microns, the gram weight is 2 grams per square meter, and the pore diameter is less than 0.3 micron. The PTFE microporous membrane is pure physical filtration, fine particles are directly intercepted by a unique microporous structure, the pore diameter of the PTFE microporous membrane is less than 0.3 micrometer, and the PTFE microporous membrane has good moisture-proof and air-permeable effects.
Example two
The waterproof glue-spraying type down-like cotton according to the present embodiment is described in detail with reference to fig. 2. The difference between this embodiment and the first embodiment is: the ultrafine fiber layer 2 includes a parallel-laid mesh layer 21 and a cross-laid mesh layer 22. In the conventional production process of the spray bonded cotton or the nonwoven material, a parallel lapping mode or a cross lapping mode is generally adopted. The mode of adopting parallel lapping has the advantage of fast production speed, and the mode of adopting cross lapping has the advantage of approximate longitudinal and transverse strength but slow production speed. The parallel lapping layer 21 and the cross lapping layer 22 are adopted, so that the production speed can be improved, and the longitudinal and transverse strengths can be close to each other without too large difference. And the superposition of the two fiber webs can reduce the irregularity of the microfiber layer 2.
EXAMPLE III
The waterproof glue-spraying type down-like cotton according to the present embodiment is described in detail with reference to fig. 3. The difference between this embodiment and the first embodiment is: the base layer 4 is formed by bonding a blended fabric 41 and a PLA fabric 43 through an adhesive 42. The adhesive 42 is a hot melt adhesive powder, specifically a copolyester adhesive powder, a copolyamide adhesive powder or a modified polyamide adhesive powder, and is selected to be a modified polyamide adhesive powder in this embodiment. And the base layer 4 is also fixed by quilting, which can effectively improve the strength of the base layer.
Example four
The waterproof glue-spraying type down-like cotton according to the present embodiment is described in detail with reference to fig. 4. The difference between this embodiment and the second embodiment is: the base layer 4 is formed by bonding a blended fabric and a PLA fabric through an adhesive. The adhesive used is a hot melt adhesive powder, specifically a copolyester adhesive powder, a copolyamide adhesive powder or a modified polyamide adhesive powder, and is selected to be a modified polyamide adhesive powder in this embodiment.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
