Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a composite non-woven bed sheet. Background Art

[0002] Traditional bed sheets are usually made of cotton or other fabric materials. Although they are soft and comfortable, they are easy to wrinkle during use, and their moisture absorption and perspiration performance are limited, which is not conducive to keeping them dry. At the same time, traditional bed sheets need to be washed repeatedly, which not only consumes a lot of water resources, but also increases the cost of use. Although disposable bed sheets solve the problem of washing, they often have problems such as thin texture, poor moisture absorption and perspiration performance, and easy to break.

[0003] In the prior art, disposable non-woven sheets have been designed, which are widely used in hotels, hospitals, travel and other places. This kind of sheet is made of non-woven material and has the characteristics of disposable use. It can be easily discarded after use, avoiding the trouble of cleaning and disinfection. Disposable non-woven sheets have the advantages of hygiene and cleanliness, which can effectively protect the health of users. When traveling, using disposable sheets can avoid contact with unclean bedding and improve sleep quality. In places such as hospitals, disposable sheets can also reduce the risk of cross infection and protect the health and safety of patients and employees.

[0004] For example, the anti-virus and anti-bacterial health combination kit with publication number CN212979485U has an anti-bacterial deodorizing layer to make the corresponding bedding kit have good anti-bacterial properties. However, the bed sheets made of non-woven fabrics have good anti-bacterial properties themselves, and the anti-bacterial deodorizing layer cannot produce outstanding effects in a short period of use. For disposable bed sheets, it is more necessary to consider their production costs, while taking into account the effects of sweat absorption, wrinkle-free and skin-friendly. Utility Model Content

[0005] In view of this, the utility model proposes a composite non-woven bed sheet, which enhances the water absorption, wrinkle resistance and tensile strength of the bed sheet by setting a spunbond hydrophilic non-woven layer as the skin-friendly surface of the bed sheet and a meltblown mixed non-woven layer. The finally set spunmelt water-repellent non-woven layer has strong waterproof performance, which can block water penetration and has certain breathability. While improving the user experience, it can effectively control the production cost of disposable bed sheets.

[0006] The technical solution of the utility model is implemented as follows: The utility model provides a composite non-woven fabric bed sheet, including a spunbond hydrophilic non-woven layer, a melt-blown mixed non-woven layer and a spunmelt water-repellent non-woven layer, wherein:

[0007] The spunbond hydrophilic nonwoven layer is used to contact the human body;

[0012] On the basis of the above technical solution, preferably, a plurality of small holes are formed on the spunbond hydrophilic nonwoven layer, and the small holes are used to enhance the water permeability of the spunbond hydrophilic nonwoven layer.

[0013] Based on the above technical solution, preferably, the diameter of the small hole is 0.5-1.5 mm.

[0014] On the basis of the above technical solution, preferably, the water-absorbing layer is a hydrophilic staple fiber cloth.

[0015] Further preferably, the meltblown mixed nonwoven layer further comprises a first meltblown fiber layer and a second meltblown fiber layer, wherein:

[0016] The first meltblown fiber layer is compounded between the water-absorbing layer and the spunbond hydrophilic nonwoven layer;

[0018] On the basis of the above technical solution, preferably, the number of the water absorbing layers is two and they are stacked.

[0019] On the basis of the above technical solution, preferably, the spunbonded hydrophilic nonwoven layer has a gram weight of 8-13 g / m 2 The melt-blown mixed nonwoven layer has a gram weight of 60-80 g / m 2 The spunmelt water-repellent nonwoven layer has a grammage of 8-13 g / m 2 .

[0020] The composite non-woven bed sheet of the utility model has the following beneficial effects compared with the prior art:

[0021] (1) By providing a spunbond hydrophilic non-woven layer as the skin-friendly surface of the bed sheet, and providing a melt-blown mixed non-woven layer, the water absorption, wrinkle resistance and tensile resistance of the bed sheet are enhanced. The spunmelt water-repellent non-woven layer provided at the end has strong waterproof performance, can block water penetration, and has certain air permeability.

At the same time, it can reduce the contact area between the bed sheet and the human body, reduce friction, and prevent the bed sheet from causing unnecessary friction stimulation to the skin when moving and turning over, which helps to reduce the pressure and discomfort of the skin. In addition, by setting the convex points, the uneven surface of the bed sheet can provide an additional massage effect, promote blood circulation, relieve muscle fatigue and tension, increase comfort, and help improve sleep quality. The set micropores can increase the air permeability of the bed sheet surface, promote air circulation, help to discharge the humid air under the bed sheet, keep the bed sheet dry, and provide a more comfortable sleeping environment.

[0023] (3) The meltblown mixed nonwoven layer can greatly increase the thickness of the bed sheet by setting a double-layer water-absorbing layer and a double-layer meltblown fiber layer, while providing better air permeability and water absorption performance, which can effectively increase the wrinkle resistance and tensile strength of the bed sheet, and effectively inhibit the growth of bacteria to keep the bed sheet clean and hygienic.

For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0025] Figure 1 It is a partial cross-sectional view of the composite non-woven fabric bed sheet of the utility model. DETAILED DESCRIPTION

[0026] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1As shown, the composite nonwoven bed sheet of the utility model comprises a spunbond hydrophilic nonwoven layer 1, a meltblown mixed nonwoven layer 2 and a spunmelt water-repellent nonwoven layer 3.

[0028] The spunbond hydrophilic non-woven layer 1 is used to contact the human body. As the hydrophilic layer of the bed sheet, the spunbond hydrophilic non-woven layer 1 has good air permeability, sweat absorption, dehumidification and non-reseepage functions. The spunbond hydrophilic non-woven layer 1 is preferably made of soft spunbond non-woven fabric. Soft spunbond non-woven fabric is a non-woven fabric material made of a mixture of textile fibers and viscose fibers. The soft spunbond non-woven fabric has a delicate touch and soft texture, which makes bedding more comfortable and provides a comfortable sleeping experience. It also has good moisture absorption and air permeability, which helps to regulate the humidity of the sleeping environment, keep the bed environment fresh and dry, and improve sleep quality. In addition, due to the mixture of textile fibers and viscose fibers, soft spunbond non-woven fabrics usually have good wear resistance and tensile strength.

[0029] The melt-blown mixed non-woven layer 2 is compounded on one side of the spunbond hydrophilic non-woven layer 1. The melt-blown mixed non-woven layer 2 is used to enhance the wrinkle and crack resistance of the bed sheet. The melt-blown mixed non-woven layer 2 includes a water-absorbing layer 21, and the water-absorbing layer 21 is used to absorb sweat. If the spunbond hydrophilic non-woven layer 1 is used alone as a bed sheet, it will result in a thin thickness and extremely limited water absorption effect. The thickness of the bed sheet will directly affect the user's sleeping experience. The melt-blown mixed non-woven layer 2 can greatly increase the thickness of the bed sheet, while providing better air permeability and water absorption performance. The melt-blown mixed non-woven layer 2 can also effectively increase the wrinkle and tensile resistance of the bed sheet.

[0030] The spunmelt water-repellent non-woven layer 3 is compounded on the side of the meltblown mixed non-woven layer 2 away from the spunbond hydrophilic non-woven layer 1, and is used to isolate moisture penetration and bacterial contamination. The spunmelt water-repellent non-woven layer is preferably a spunmelt water-repellent non-woven fabric. The spunmelt water-repellent non-woven fabric has excellent waterproof properties, which can effectively block moisture penetration, prevent sheets or mattresses from getting damp, and keep bedding dry and clean. Due to its water-repellent properties, the spunmelt water-repellent non-woven fabric can resist the invasion of stains to a certain extent, making it difficult for stains to penetrate into the fabric, making it convenient to clean and maintain. Although it is a waterproof material, the spunmelt water-repellent non-woven fabric still maintains good air permeability, which helps to maintain ventilation and comfort of the bed environment and improve sleep quality. The application of spunmelt water-repellent non-woven fabric in this solution can provide users with a more comfortable, clean and healthy sleeping environment, while also having certain protective functions.

[0031] During the production process, the spunbond hydrophilic nonwoven layer 1, the meltblown mixed nonwoven layer 2 and the spunmelt water-repellent nonwoven layer 3 are compounded together through thermal bonding technology to form an integral structure. The design of this composite structure takes into account the role of different functional layers to improve the performance and ease of use of the nonwoven fabric. During the bonding process, the spunbond hydrophilic nonwoven layer 1 and the spunmelt water-repellent nonwoven layer 3 are the same size, which helps to ensure the balance and consistency of the overall structure. The length and width of the meltblown mixed nonwoven layer 2 are slightly smaller than the upper and lower layers, specifically 0.3-1cm. The purpose of this design is to allow the spunbond hydrophilic nonwoven layer 1 and the spunmelt water-repellent nonwoven layer 3 to exceed the meltblown mixed nonwoven layer 2 to perform edge sealing of the bed sheet, effectively preventing the uneven wood pulp composition and wood pulp scattering in the cross section of the meltblown mixed nonwoven layer 2. Through this size design, the uniformity and stability of the reinforcing layer can be ensured, and the strength and durability of the overall structure can be improved.

[0032] As a preferred embodiment, the spunbond hydrophilic non-woven layer 1 is provided with a plurality of protrusions, and the protrusions are used to reduce the contact area between the human body and the spunbond hydrophilic non-woven layer 1. The protrusion design can increase the gap between the bed sheet and the human skin, promote air circulation, improve the ventilation and air permeability of the bed sheet, help regulate temperature and humidity, and provide a more comfortable sleeping environment. At the same time, it can reduce the contact area between the bed sheet and the human body, reduce friction, and prevent the bed sheet from causing unnecessary friction stimulation to the skin when moving and turning over, which helps to reduce skin pressure and discomfort. In addition, by setting the protrusions, the uneven surface of the bed sheet can provide additional massage effects, promote blood circulation, relieve muscle fatigue and tension, increase comfort, and help improve sleep quality.

[0033] Specifically, the number of the protrusions is 5-7 per square centimeter. The protrusions can be formed by rolling after the sheets are composited. The number of protrusions per square centimeter may be inconsistent due to the rolling process and unit selection, but it will not affect subsequent use.

[0034] As a preferred embodiment, a plurality of small holes are provided on the spunbond hydrophilic nonwoven layer 1, and the small holes are used to enhance the water permeability of the spunbond hydrophilic nonwoven layer 1. Specifically, the aperture of the small holes is 0.5-1.5 mm. During the production process, the aperture of the small holes can be selected to be 1 mm. The provided small holes can increase the air permeability of the surface of the sheets, promote air circulation, help to discharge the humid air under the sheets, keep the sheets dry, and provide a more comfortable sleeping environment. At the same time, it helps to regulate humidity, prevent excessive moisture from accumulating on the surface of the sheets, reduce the possibility of mold and bacteria growth, and keep the sheets clean and hygienic. In addition, it can also help the surface of the sheets release heat and regulate the temperature, making the human body feel more comfortable when sleeping and avoiding overheating or overcooling. The appropriate amount of small hole design can make the sheets softer, more skin-fitting, improve tactile comfort, and increase sleep comfort.

[0035] In the present embodiment, the water-absorbing layer 21 is a hydrophilic staple fiber cloth, which is formed by pressing staple fibers. The hydrophilic staple fibers are at least one of hydrophilic chemical fibers, wood pulp, cotton fibers, linen fibers and high molecular water-absorbing resins. It can be a single material or a mixture of the above materials. There are many choices of hydrophilic chemical fibers according to the specific product selection. Among them, bicomponent fibers and curly fibers have their own characteristics. Bicomponent fibers have the function of preventing chipping, and curly fibers have the function of increasing thickness. Considering that certain burrs and shedding will be generated during the production and cutting process of the staple fibers of the water-absorbing layer 21, the above-mentioned edge sealing setting is used to reinforce the water-absorbing layer 21.

[0036] As a preferred embodiment, the meltblown mixed nonwoven layer 2 also includes a first meltblown fiber layer 22 and a second meltblown fiber layer 23. The first meltblown fiber layer 22 is compounded between the water-absorbing layer 21 and the spunbond hydrophilic nonwoven layer 1, and the second meltblown fiber layer 23 is compounded between the water-absorbing layer 21 and the spunbond water-repellent nonwoven layer 3. The first meltblown fiber layer 22 and the second meltblown fiber layer 23 are used to compress the staple fibers on the water-absorbing layer 21 and increase the overall hardness of the sheet.

[0037] During the production process, the meltblown mixed non-woven layer 2 needs to be composited separately and then composited with the spunbond hydrophilic non-woven layer 1 and the spunmelt water-repellent non-woven layer 3. The first meltblown fiber layer 22, the water-absorbing layer 21 and the second meltblown fiber layer 23 can be pressed together by a pair of point hot rolling rollers after arrangement. The first meltblown fiber layer 22 and the second meltblown fiber layer 23 can be used to press the water-absorbing layer 21 during the production process of the meltblown mixed non-woven layer 2, and prevent the short fibers from detaching and affecting the environment. At the same time, the meltblown fiber cloth has good water absorption, can quickly absorb sweat on the skin surface, keep the skin dry and comfortable, improve sleep quality, and can effectively inhibit bacterial growth, keep the sheets clean and hygienic. As disposable sheets, two layers of meltblown fiber cloth can effectively inhibit bacterial growth within a certain period of time and protect the hygienic and healthy sleeping environment.

[0038] It should be noted that the first meltblown fiber layer 22 needs to be hydrophilic so that the liquid can penetrate into the water-absorbing layer 21 through the first meltblown fiber layer 22. The hydrophilic process has been recorded in the prior art and will not be described again here.

[0039] As a preferred embodiment, the number of the water-absorbing layers 21 is two, and they are stacked. The double-layer water-absorbing layer 21 further increases the thickness and water absorption performance of the bed sheet, while improving the softness and comfort of the bed sheet.

[0040] In this embodiment, the spunbonded hydrophilic nonwoven layer 1 has a gram weight of 8-13 g / m 2 The melt-blown mixed nonwoven layer 2 has a gram weight of 60-80 g / m2 The spunmelt water-repellent nonwoven layer 3 has a gram weight of 8-13 g / m 2 For the finished sheets, the weight can be basically guaranteed to be 100g / m 2 , or so, the production consumables are moderate, and there is no need to use consumables with higher costs, so that the production cost of the bed sheet can be effectively controlled, with good economy.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
