Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of household goods more particularly relates to a 0 glue mattress. BACKGROUND

[0002] In recent years, the mattress industry has been continuously innovating in terms of materials and processes, aiming to enhance the sleep experience of consumers. However, during the production process of traditional mattresses, especially when using processes involving glue, there are still some obvious drawbacks. These drawbacks not only affect the performance, comfort, and durability of the mattress, but also pose challenges to the health and environmental protection needs of consumers. The following are the main drawbacks of existing mattresses with glue processes:

[0003] 1. Environmental pollution and health risks

[0004] In the manufacturing process of traditional mattresses, glue is widely used as an adhesive to bond different material layers. Most of the glue used in mattresses is synthetic resin-based glue based on chemical components. This type of glue often contains volatile organic compounds (VOCs) and other harmful chemicals. Over time, these harmful chemicals can volatilize from the mattress into the air, causing indoor air pollution and posing potential health risks to users, especially to groups sensitive to the respiratory system (such as infants, the elderly, and people with allergies), which may cause skin allergies, respiratory irritation, and other problems.

[0005] 2. Reduced comfort

[0006] Glue plays a role in bonding in multiple layers of the mattress, but the hardness and rigidity of the glue itself can cause some areas of the mattress to become too hard or uneven. Over time, the glue may age, become brittle, or soften due to environmental factors such as temperature and humidity changes, affecting the comfort and support of the mattress, causing the mattress to deform or sag during use, and affecting the user's sleep experience.

[0007] 3. Reduced mattress durability

[0008] Due to the quality and stability of the glue, over time, the glue inside the mattress may fall off or fail, causing the structure of the mattress to become loose, affecting the overall stability and durability of the mattress. In particular, after a long period of compression and stretching, the adhesive effect of the glue may gradually weaken, resulting in reduced support of the mattress and even material separation. This problem not only shortens the service life of the mattress, but also requires consumers to frequently replace or repair it.

[0009] Bed mattresses that do not use environmentally friendly adhesives often rely on chemical synthetic materials during production, which can cause environmental pollution during the production process. Especially during the recycling process of the mattress, due to the difficulty of effectively recycling or decomposing the adhesive, it may increase the difficulty of mattress waste disposal and bring greater environmental pressure. With the improvement of environmental awareness, more and more consumers tend to choose environmentally friendly mattresses without harmful chemicals, but the existing mattress process containing adhesives cannot meet this demand.

[0010] 4. Odor problem

[0011] Mattresses containing chemical adhesives may emit a pungent odor, especially during initial use. This odor comes from volatile organic compounds (VOCs) in the adhesive. Although modern mattress manufacturers usually perform some "ventilation" treatment to reduce this odor, the residual odor is still one of the issues that consumers often pay attention to when purchasing a mattress. Long-term exposure to an environment containing harmful chemical gases can affect human health and increase consumer dissatisfaction.

[0012] In summary, the existing mattress process containing adhesives has significant problems in environmental protection, health, comfort, etc. These problems not only limit the further development of mattress technology, but also make consumers face more concerns when choosing a mattress. Therefore, it is necessary to develop a more environmentally friendly, healthy, comfortable and durable mattress manufacturing process to meet the needs of modern consumers for high-quality sleep environments.
