Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a light-shielding and breathable soft sheet-like object, a quilt, a fabric, a curtain or a package or a wrapping object. Background Art

[0002] Traditional quilts, fabrics, blackout curtains, blackout cloths, packaging, and wrappings cannot block light and ventilate at the same time. For example, curtains (bed curtains) block light and protect privacy, but they cause poor air circulation; clothes with holes for cool ventilation have good ventilation and coolness, but they expose the body; hats without tops effectively dissipate heat, but hair is more susceptible to sunburn; some people like to cover their heads with quilts when sleeping, which can improve sleep quality by blocking light, but it can easily cause health problems due to poor air circulation and pressure on the eyeballs; some packaging materials and covers used in biomedical products also have the need to block light and be ventilated.

[0003] There is a great demand for all the above aspects. Taking quilts as an example, the factors that affect sleep are mainly light, sound, and appliances. Judging from the purchase of sleep aids by Chinese netizens in 2021, 43.5% of netizens bought eye masks and eye patches; 30.1% of netizens bought cassia seeds and latex pillows; 25.8% of netizens chose to buy soundproof earplugs. The above three aspects correspond to light, appliance comfort, and noise, which are the main reasons affecting sleep. Sleeping with your head covered can effectively block the influence of light and reduce the influence of sound, but because the air is not smooth when sleeping with your head covered, and the weight of the covering creates a sense of oppression, the comfort is poor, and it is easy to cause health problems of the eyes and respiratory system; some textile fabrics need to block sight and have ventilation and cooling functions; therefore, light-blocking and breathable quilts are needed to meet the corresponding needs.

[0004] Publication number CN215457040U discloses an antibacterial and skin-friendly silk quilt, comprising a quilt core, a quilt core covered with a quilt cover, a plurality of ventilation holes provided at the front end of the quilt core, baffles provided at both ends of the ventilation holes, the baffles provided with a plurality of small holes, a cloth tube fixedly connected to the inner wall of the ventilation hole, a spherical ball provided on the inner wall of the cloth tube, the spherical ball provided with a plurality of circular holes, the spherical ball is hollow, and negative ion material is provided inside.

[0005] This solution has the following defects: First, the solid part of the quilt core is usually relatively heavy, which will cause pressure on the eyes and face, resulting in poor comfort and easily causing health problems, especially health problems caused by pressure on the eyes. Second, it is necessary to set up a lot of through holes, each of which needs to be connected to a cloth cover, each cloth cover needs to be fixed to the quilt core, and a sphere with several round holes needs to be added, and baffles with several small holes are set at both ends of the vent. Therefore, the process is complicated, the processing is difficult, and high precision is required; third, the complex process and numerous component materials result in high labor (processing) and material costs and inventory management procurement costs; fourth, the air needs to pass through the baffles on both sides, the gap between the sphere and the baffles on both sides, the holes above and below the small ball, and the internal space of the small ball, a total of seven air channels. The air passes through each air channel, especially the connection. The airflow will be hindered. The small ball with through holes will hinder the air circulation more and the ventilation effect is poor; fifth, the round hole of the small ball needs to be fixed upward and downward at both ends. First, it takes time and effort to ensure the position and direction of the small hole during processing. Second, the sphere is easy to rotate, which will cause the two ends of the small hole to turn to the cloth cover and the air channel to be blocked; sixth, the round hole of the small ball is easy to transmit light. Utility Model Content

[0006] In order to solve the above problems, the utility model provides a light-shielding and breathable soft sheet, and a quilt and fabric using the above soft sheet to achieve the light-shielding and breathable effect. The utility model has the unique effect that thick materials are more breathable, cooler and lighter than traditional thin materials. In order to meet the needs of certain application scenarios, an embodiment of the utility model creatively adopts a porous material support layer + a three-dimensional mesh structure to achieve excellent air permeability, ultra-light weight, and a certain sound absorption effect.

[0007] The meaning and scope of some terms in the utility model are as follows: Light blocking includes completely opaque and semi-transparent. The opening of porous materials means that the pores are interconnected. Open-pore porous materials refer to porous materials with fully open pores or mainly open pores. Fabrics include fabrics used in the fields of clothing and textiles, home textiles and home furnishings, industrial textiles, sports and outdoor, packaging, and wrapping.

[0008] The technical solution provided by the utility model is as follows:

[0009] The first aspect of the utility model provides a light-shielding and breathable soft sheet-like object, comprising a first light-shielding layer, a first ventilation layer and a second light-shielding layer, characterized in that: the first ventilation layer is located between the first light-shielding layer and the second light-shielding layer, the first light-shielding layer is provided with a plurality of first ventilation holes, the second light-shielding layer is provided with a plurality of second ventilation holes, the positions of the first ventilation holes and the second ventilation holes are staggered, and the first ventilation layer is an open-hole porous material layer.

[0010] There are many classifications and subdivisions of porous materials in the industry and literature. The open pores of the porous materials described in this utility model refer to pores that are interconnected. Actual porous materials sometimes have both open pores and closed pores. The open-pore porous materials described in this utility model refer to porous materials with fully open pores or mainly open pores.

[0011] Preferably, the first ventilation layer is an open-cell foam plastic layer.

[0012] Foam plastics usually have a much higher specific strength than other porous materials, so they have high comprehensive performance in terms of support, volume and weight, and are characterized by low cost and simple molding process.

[0013] Preferably, the first ventilation layer is a three-dimensional mesh structure.

[0014] Preferably, the first ventilation layer is made of one of filter cotton, loofah, 3D mesh cloth, upright cotton and sponge.

[0015] Preferably, a second ventilation layer and a third light-shielding layer are provided, the second ventilation layer is located between the second light-shielding layer and the third light-shielding layer, the third light-shielding layer is provided with a plurality of third ventilation holes, and the second ventilation layer adopts the structure of the first ventilation layer.

[0016] In a second aspect, the utility model provides a quilt, which adopts the soft sheet-like object described in the first aspect.

[0017] In a third aspect, the utility model provides a fabric, which adopts the soft sheet-like object described in the first aspect.

[0018] In a fourth aspect, the utility model provides a blackout curtain, which adopts the soft sheet-like object described in the first aspect.

[0019] In a fifth aspect, the utility model provides a packaging material, which adopts the soft sheet material described in the first aspect.

[0020] In a sixth aspect, the utility model provides a bandage, which adopts the soft sheet-like object described in the first aspect.

[0021] The beneficial effects of the soft sheet-like object and some products of the utility model are as follows: 1. The ventilation holes of several layers of light-shielding layers are arranged in an offset manner to achieve the light-shielding effect. The ventilation layer forms a stable support to ensure the long-lasting stability of the ventilation structure. The ventilation holes of several layers of light-shielding layers pass through the pores of the porous material of the ventilation layer to form an air passage that penetrates the entire soft sheet-like object to achieve ventilation, thereby achieving a stable light-shielding and ventilation effect. 2. Excellent ventilation effect. Using the open-porous porous material solution, since the porosity of the high-porosity porous material can reach 90-98% or higher, the solid part that hinders the passage of air is only 2-10%, or less than 2%. Such a small solid support volume has very little air blocking. 3. The ventilation layer uses the open-porous porous material layer solution. The ventilation layer and the light-shielding layer can be freely attached to achieve a good ventilation effect. The light-shielding layer does not need to align the multiple layers of ventilation holes according to a certain relative position like the traditional through-hole solution, which greatly reduces the processing difficulty and precision requirements, reduces the processing steps, reduces the processing cost and time cost, and improves the yield and efficiency. 4. The shading effect can be achieved by adjusting the position of the vent holes of the shading layer and setting the number of shading layers, so as to achieve different shading requirements such as full shading, semi-shading, and only blocking peeping. 5. The porous material is ultra-light. For example, the weight of the porous material with a porosity of 98% is only about 2% of the same volume and material, and the corresponding weight is only about 2% of the ordinary material. The sense of oppression caused by this part of the material is close to zero, and the sense of comfort is strong, and it will not cause health problems such as oppression of the face or eyes. 6. Through the setting of the ventilation structure, the unique effect of thick materials being more ventilated, cooler, and lighter than traditional thin materials is achieved. 7. The production requirements are simple, which reduces the processing cost and makes the product more cost-effective. 8. All degradable materials can be used, which complies with the green building and green home policies, and contributes to environmental protection and sustainable development. 9. The shading and comfort are strong, and some scenes have sound absorption effects, which effectively avoid the problems caused by the main factors affecting sleep and indoor environment, such as light, sound, and comfort of appliances. 10. The three-dimensional mesh structure achieves a leap in breathability and lightweight quality.

[0022] The beneficial effects of using the quilt provided by the utility model to cover the head for sleeping are: first, better sleep. According to the purchase of sleep aids by Chinese netizens in 2021, 43.5% of netizens bought eye masks and eye patches; 30.1% of netizens bought cassia seeds and latex pillows; 25.8% of netizens chose to buy soundproof earplugs. The above three aspects correspond to light, appliance comfort and noise, which are the main reasons affecting sleep. The utility model can effectively block the influence of light because it is light-shielding and breathable; because the open-porous material has a sound-absorbing effect, it can reduce the influence of noise. The main components are made of open-porous materials, which are light in weight and highly breathable, effectively block light, absorb sound and are comfortable, solve the problems of light, noise and appliance comfort, and help users sleep better. Second, it improves brain function and cognitive skills such as memory, word association and reaction time. Better memory can improve learning and work performance, and faster reaction time is critical in sports, driving or other situations where quick response is crucial. The research results of Dr. Viviana Greco from the Brain Research Imaging Center of Cardiff University in Wales and the opinions of Dr. Thomas Preston from the Department of Neurology of Stony Brook School of Medicine in New York State confirm that wearing an eye mask to sleep has the above effects. However, there are many problems with wearing an eye mask to sleep, such as pressure on the eyeballs when sleeping, automatic falling off, feeling scared when the eyes are covered, pinching the ears, not being able to prevent noise, poor light blocking, feeling stuffy, etc., resulting in the use of the eye mask is not popular relative to the total population demand. The quilt provided by the utility model does not have the above problems, and has better effects in terms of light blocking, sound absorption and comfort. BRIEF DESCRIPTION OF THE DRAWINGS
