Description

Technical Field

[0001] The invention relates to the technical field of antibacterial mattresses, in particular to a highly elastic and compressible antibacterial mattress and a preparation process thereof. Background Art

[0002] Although the existing jute mattresses have the advantages of being environmentally friendly, healthy, insect-proof, anti-mite and antibacterial, good air permeability, strong support and durability, they also have the disadvantages of being heavy and hard. This means that when producing and processing jute palm mats, they cannot be compressed or rolled, and can only be produced and processed one by one, resulting in low production efficiency. In particular, when processing the entire mattress based on the jute palm mat, it is difficult to carry out mechanical automated mass production. Either traditional extremely inefficient full manual processing can be used, or at most a combination of manual and semi-mechanized processing can be used for relatively low efficiency processing, but efficient mechanical fully automated production is impossible.

[0003] The existing spring mattresses are generally made of networked springs or independent springs plus non-woven fabrics or PK cotton. The non-woven fabrics or PK cotton are too thin or have too low a gram weight. People sleeping on the bed can easily feel the presence of the springs, which feels stiff. Moreover, the non-woven fabrics or PK cotton are purely chemical materials, which are not environmentally friendly and healthy, are not breathable, and can easily cause allergies and other problems. The mattresses are not comfortable and do not have natural insect-proof, anti-mite and antibacterial effects.

[0047] The present invention also proposes a preparation process of a highly elastic and compressible antibacterial mattress, comprising the following steps:

[0048] S1. Spring preparation: According to the specifications of Yunnian high compression spring, select wire suitable for high elastic spring 63, the cross-section diameter of the wire is 1.8-1.95 mm, use a shearing machine to cut the wire into the required length, and use a wire straightening machine to ensure that the wire is straight and without bending, put the wire into a melting furnace and heat it to a molten state, pour the molten metal into the mold of Yunnian high compression spring, use a die-casting machine to apply pressure to the mold, so that the metal is fully filled and solidified in the mold to form a fused spring structure, take the fused spring out of the mold, quickly put it into a cooling water tank to cool to room temperature, use an air cooling device to further accelerate the cooling process, use a grinder to grind the surface of the high elastic spring 63 to remove burrs and uneven parts, and use a polishing machine to polish the spring to improve its surface finish and aesthetics;

[0049] S2 spring assembly: The processed high elastic spring 63 is loaded into the spring bag 62 to form a complete independent pocket spring 61, each spring bag 62 is made of 70-75 grams of non-woven fabric or cool cloth material, a length of 18cm, a high elastic spring 63 is 36cm 6.5 turns olive-shaped spring;

[0050] Through step S2, the spring is designed to be olive-shaped, that is, the coils at the two ends are small and gradually increase toward the middle coil. The sizes of the two adjacent coils are different, and the force surface and force value of each coil are also different. When the spring is fully compressed, the steel wires of the two adjacent coils will stagger with each other, and will not collide directly with each other, which not only solves the problem of the sound produced by the collision of the spring steel wires, but also solves the stiff feeling caused by the direct collision of the spring steel wires. No matter how much pressure is generated on the mattress, not only will there be no creaking noise caused by the mattress spring being compressed, but the mattress will not feel stiff. In addition, because of the olive-shaped design of the present invention, the force surface and force value of each coil of the spring are different, and the force value increases continuously from the two ends to the middle. When the spring is under pressure, the force transmission is also progressive from the two ends to the middle layer. When the spring is under strong pressure, due to the strong force surface and force value of the middle coil of the spring, the spring can withstand the strong pressure without deformation and damage. After the strong pressure is released, the spring can rebound and return to its original state. The mattress made of the spring has strong pressure-bearing performance and strong rebound performance;

[0051] S3 jute layer preparation: the jute silk layer 52 and the hot melt cotton layer 51 according to the ratio of 1:9, by 180-200 degrees hot pressing process, high temperature hot pressing for 5-10 minutes, forming a jute and hot melt cotton bonded body, ie, hot pressing bonding layer 53;

[0052] S4. Laying jute silk: Jute silk is laid on both sides of the hot-pressed bonding layer 53, so that the ratio of jute to hot-melt cotton is adjusted to 3:7, constituting a jute layer A5 and a jute layer B7, wherein the hot-pressed bonding layer 53 is located in the middle, and a jute silk layer 52 is provided on both sides of the outside;

[0053] S5. Needle punching process: using a dense needle punching process, the jute layer A5 and the jute layer B7 with jute silk laid on them are pierced back and forth at a density of 1-2 cm to form a jute layer A5 and a jute layer B7 with needle punching that is fully integrated with the hot melt cotton and is uniform and flat;

[0054] Through step S3 to step S5, the surfaces of both sides of the obtained jute layer are flat without checkered or striped embossing, making the entire jute layer appear soft and delicate. At the same time, it is a three-dimensional needle-punched cross structure, so that the jute and the hot-melt cotton are fully cross-fused. The entire jute layer is integrated, there is no material stratification phenomenon, and there is no jute silk falling off and delamination. The entire jute layer is strong and tear-resistant. During mechanical automated production, the jute layer can be easily rolled without losing silk or delamination. When the next process uses a machine to automatically unfold the rolled jute layer, it is also neat and smooth without losing silk or delamination, which greatly improves the production yield rate;

[0055] S6. Preparation of air honeycomb silicone cotton layer: The air honeycomb silicone cotton is blasted with ammonia high-pressure air to produce honeycomb-shaped honeycomb holes 41 on the sponge. The honeycomb silicone cotton is placed in a silicone liquid pool and squeezed back and forth using a high-temperature thermal imaging process to allow the silicone liquid to pass through the structure of all the honeycomb holes on the honeycomb silicone cotton and wrap a layer of silicone liquid layer 43. The honeycomb silicone cotton fully soaked with silicone liquid is placed in a high-temperature blow box for drying, and then cooled after drying to form air honeycomb silicone cotton layer A4 and air honeycomb silicone cotton layer B8;

[0056] The air honeycomb silicone sponge obtained in step S6 is fully soaked with silicone inside, and the entire sponge is wrapped with silicone. Silicone is a food-grade material that infants and young children can directly touch. Therefore, the silicone sponge is more environmentally friendly and safer than ordinary sponges, and is stronger and more resistant to pulling, and is also softer and more elastic.

[0057] S7. Mattress assembly: Lay fabric layer 2, high elastic cotton layer 3, air honeycomb silicone cotton layer A4, jute layer A5, combined spring bag 6, jute layer B7, air honeycomb silicone cotton layer B8 and 3D breathable fabric layer 9 on the top of the mattress body 1 in sequence, and conduct a final inspection on the assembled mattress to ensure that the layers are tightly connected and there is no looseness or displacement;

[0058] Example

[0059] The mattress of the present invention is subjected to a sleep test, and the steps are as follows:

[0060] 1. Simulation experiment:

[0061] The indoor environment during the transition from autumn to winter (temperature 10°C, RH 50%) was simulated to monitor sleep brain waves. The duration of falling asleep and deep sleep time were calculated based on the sleep stages of the American Academy of Sleep Medicine (AASM), which is well-known and widely used in the world. The total sleep time, sleep efficiency and sleep duration distribution of the human body in different stages under the two mattress systems were compared.

[0062] The sleep stages of the human body include wakefulness and sleep, among which sleep is divided into rapid eye movement sleep (REM) and non-rapid eye movement sleep (NREM). NREM can be divided into three stages: N1, N2, and N3.

[0063] The sum of the durations of N1 and N2 is the duration of light sleep, and the duration of N3 is the duration of deep sleep;

[0064] See also Figure 6 , the definitions of relevant indicators are as follows:

[0065] Total sleep time = the time from when the person turns off the lights and lies in bed to the end of the experiment;

[0066] Total sleeping time = total sleeping time - time when the human body is awake;

[0067] Sleep efficiency = total sleeping time / total sleeping time × 100%;

[0068] Sleep satisfaction: After sleep, the subjects' thermal and moisture comfort and subjective evaluation of sleeping effect were investigated based on the Verran and Snyder-Ha l pern (VSH) sleep scale, and the final scores of the two were compared to verify sleep comfort;

[0069] See also Figure 7 , Temperature and humidity measurement: The internationally accepted 7-point collection method is used to measure the average skin temperature curve during 8 hours of sleep; at the same time, the average sleep humidity during 8 hours of sleep is measured in the back and waist area, and the average sleep humidity of the human body under the two mattress systems is compared;

[0070] The measurement of average skin temperature and relative humidity is to compare whether the human body is in the same comfortable sleeping environment when using ordinary mattress systems and Börlind True Deep Sleep mattress systems;

[0071] Heart rate: Use sleep EEG test equipment to measure the real-time heart rate curve during 8 hours of sleep, and compare whether the sleeping state of the human body is the same under the two mattress conditions;

[0072] 2. Research results and analysis of the mattress of the present invention

[0073] (1) Sleep quality: Deep sleep time was as long as 121.19 minutes, an increase of 4.65%, and sleep efficiency was as high as 90.63%;

[0074] According to AASM, sleep can be divided into five stages according to rhythm: awake, REM, N1, N2, and N3. These stages cycle back and forth. REM and N1 are light sleep stages, which are greatly affected by the environment; N2 and N3 are moderate and deep sleep stages, respectively, which are less affected by the environment;

[0075] The more deep sleep you have, the better your sleep quality;

[0076] See also Figure 8 , blue is the product of the present invention, brown is the traditional mattress, sleep quality of the mattress of the present invention and the traditional mattress, where T IB is the total effective recording time, i.e. 480 min;

[0077] Compared with traditional mattresses, the W and N1 sleep stages of the mattress of the present invention are reduced, while the N2 and N3 sleep stages are significantly improved;

[0078] The proportion of light sleep was shortened from 59.74% T IB to 59.21% T IB, a year-on-year decrease of 0.89%; the proportion of deep sleep was extended from 24.73% T IB to 25.88% T IB, which was extended by 5.52 minutes, a year-on-year increase of 4.65%;

[0079] Sleep efficiency increased from 89.54% to 90.63%;

[0080] It can be seen that the mattress of the present invention has better sleep quality and helps to prolong deep sleep time;

[0081] Comfortable temperature and humidity measurement - average skin temperature of 34.05℃ and relative humidity of 51.19% are in line with the human body's comfortable sleep;

[0082] Human skin temperature is an important physiological parameter and has been used in thermal comfort research for a long time.

[0083] As early as 1935, Burton et al. proposed that an important condition for maintaining human thermal comfort is that the average skin temperature meets certain comfort requirements;

[0084] When studying the correspondence between average skin temperature and thermal comfort, Zhou Hao found that the average skin temperature for maintaining comfortable sleep is 34.1°C, and the acceptable comfortable temperature range is 32.5°C to 35.7°C.

[0085] Roh l es found through sleep experiments that the average skin temperature of subjects in a thermally comfortable state was 34.7-35.6°C;

[0086] In addition, the study by Song et al. showed that the humidity of the internal microclimate was maintained at 40% to 60% for thermal comfort. The results may vary depending on the measurement method and location.

[0087] In summary, when the average skin temperature was between 32.5°C and 35.6°C and the relative humidity was between 40% and 60%, the subjects in the experiment were in a thermal and humid comfort state;

[0088] The temperature and humidity results during 8 hours of sleep are as follows Fig. 9 As shown, the blue line in the figure is the product of the present invention, and the yellow line is the traditional mattress;

[0089] When sleeping with the mattress of the present invention and the traditional mattress, the average skin temperature of the human body was 34.05°C and 34.07°C respectively, the relative humidity of the waist was 52.4% and 59.41% respectively, and the relative humidity of the back was 49.98% and 50.26% respectively;

[0090] It can be seen that when using the two mattress systems, the average skin temperature of the human body is within the temperature range for the human body to maintain comfortable sleep (32.5°C to 35.6°C); in addition, the human body humidity is also within the comfortable range, indicating that both mattress systems can maintain good thermal and humidity comfort during sleep, and the humidity of the human waist is lower when using the mattress of the present invention.

[0091] Subjective evaluation of sleep: falling asleep more peacefully, an increase of 14.69%, and sleep satisfaction increased by 9.5%

[0092] The subjects were asked to express their satisfaction before and after sleep, and the sleep experiment was evaluated subjectively;

[0093] The questionnaire covers thermal comfort and sleep conditions (whether the sleep is peaceful, whether it is easy to fall asleep, whether it is easy to wake up, whether you feel refreshed the next day, and satisfaction with sleep), etc. Please refer to Fig.10 In the figure, the blue one is the mattress of the present invention, and the green one is the traditional bedding:

[0094] The results of the questionnaire survey show that the mattress of the present invention has higher thermal and moist comfort than the traditional mattress, and its comfort level is close to the very comfortable level. As for the sleep quality, after using the mattress of the present invention, it is easier to fall asleep (increased from 3.5 to 4, an increase of 14.29%), it is not easy to wake up after sleep (decreased from 3 to 2.5, a decrease of 16.67%), and you feel refreshed after sleep (increased from 4 to 4.25, an increase of 6.25%). The overall satisfaction is high (increased from 4 to 4.38, an increase of 9.5%), which is consistent with the objective data and further proves the scientificity and credibility of the present invention.

[0095] Through the above steps, the mattress of the present invention can be subjected to strong pressure and the entire mattress is in a completely compressed state, and can be rolled into a roll for packing, which solves the problems that traditional mattresses are large and heavy, have high packing costs and difficulties, occupy a large area during storage and transportation, and have high costs. The mattress of the present invention greatly reduces the packing space requirements, greatly reduces the packing costs, and greatly reduces the storage and transportation costs. It is also beneficial for users to receive goods into elevators and rooms, etc. After the customer receives the mattress and unpacks it, the completely compressed mattress can rebound and recover to its original state, and the performance is completely unaffected. The mattress has high hardness, good elasticity, and high quietness. At the same time, the mattress uses the independently developed antibacterial jute layer, which makes the mattress have the advantages of high hardness, strong support, environmental protection and health, good air permeability, insect and mite resistance, and antibacterial.

[0096] In summary, the highly elastic, compressible and antibacterial mattress can be produced mechanically and automatically, is convenient for packing and transportation, and has high hardness, good elasticity, high quietness, good air permeability, and the effects of preventing insects, mites and antibacterial.

[0097] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
