Analysis of quality and environmental protection problems of mattress products in my country

Author: Synwin–Custom Mattress

Mattress is one of the important durable consumer goods in home life, and its quality directly affects people's health. There are three main types of mattress products in my country: spring soft mattresses, brown fiber elastic mattresses, and foam mattresses. Spring soft mattress refers to the bedding made of spring and soft pad as the inner core material, and the surface is covered with other materials such as fabric fabric or soft seat.

Brown fiber elastic mattress refers to an elastic material with a porous structure formed by using natural brown fiber as the main material, and using adhesive to make them adhere to each other or adopt other connection methods. Foamed mattress refers to a mattress made of natural latex, synthetic latex, polyurethane and other materials, which are formed by foaming process as the main core material, and the surface is covered with fabrics and other materials. 1 Product Standards and Main Quality Standards The product standards and important quality and environmental protection standards involved in mattress products are as follows: QB/T 1952.2—2011 "Spring Soft Mattress for Upholstered Furniture"; GB/T 26706—2011 "Brown Fiber Elastic Bed for Upholstered Furniture" Mats"; QB/T 4839-2015 "Foam Mattresses for Upholstered Furniture"; GB 18587-2001 "Limits of Harmful Substances Released for Interior Decoration Materials Carpets, Carpet Liners and Carpet Adhesives"; GB 17927.1-2011 "Upholstered Furniture Beds" Evaluation of the ignition resistance of cushions and sofas - Part 1: Smoldering cigarettes"; GB 17927.2—2011 "Evaluation of the ignition resistance of upholstered furniture, mattresses and sofas - Part 1: Simulated match flame"; QB/T 1952.2— 2011 "Spring Soft Mattress for Soft Furniture" mainly stipulates the size deviation, fabric appearance, seam quality, physical properties of fabrics and bedding materials, hygiene and safety indicators, anti-mite performance, spring quality and mechanical and physical properties of spring soft mattresses Wait.

GB/T 26706-2011 "Soft Furniture - Brown Fiber Elastic Mattress" mainly stipulates the size deviation, fabric appearance and performance, core material appearance and performance, safety and health requirements, flame retardant performance and durability of brown fiber elastic mattresses. QB/T 4839-2015 "Foam Mattress for Upholstered Furniture" mainly specifies the size deviation, appearance of fabric, seam quality of seam surface, physical properties of fabric and core material, flame retardancy and anti-mite performance of foam mattress. , formaldehyde emission, diisocyanate monomer and mechanical and physical properties. 2 Common quality and environmental protection issues ) felt, coconut mats and other materials.

The core materials of the palm fiber elastic mattress mainly include mountain palm fiber mat, coconut palm fiber mat and oil palm fiber mat. In recent years, a new type of environmentally friendly core material, commonly known as environmentally friendly brown, has appeared on the market. The hardness of this material is relatively high, which meets the needs of some consumers who like to sleep on hard mattresses.

The core material of foam mattress mainly includes foam plastic, natural latex, synthetic latex and other materials formed by foaming process. The quality and environmental protection issues of bedding materials mainly focus on foam plastics and hygiene requirements. The mattress surface will be crushed to a certain extent during use, and the resilience performance of the foam is related to the ability of the mattress surface to recover after being compressed.

The foam resilience is not up to standard, which will cause pits on the surface of the mattress and affect the comfort of the product. The hygienic requirements of bedding materials are an important quality and environmental protection index in mattress products. The quality of the bedding material used in the mattress is related to personal health and safety and the feeling of use.

The main reason for the non-compliance with the sanitary requirements of bedding materials is that the bedding materials are mixed with plastic woven materials, plant straws or leaves, shells, bamboo silk and wood shavings, and some use similar waste fiber products. Plastic woven materials are often used packaging bags, and some packaging bags are even loaded with chemical materials such as chemicals and fertilizers. These waste fiber products and plastic woven materials are extremely easy to breed harmful bacteria and harmful substances in long-term use. , seriously affect people's health. 2.2 Flame retardancy Flame retardancy is another important quality indicator of mattress products.

The raw materials used in mattresses are generally flammable fabrics, foam plastics, cotton felt pads, etc. Therefore, mattresses need to have a certain resistance to ignition. my country has put forward different flame retardancy requirements for mattress products for households and public places. Family mattresses need to pass the anti-ignition test of smoldering cigarettes, that is, the anti-ignition properties should meet the requirements of GB 17927.1-2011; public places Mattresses used must pass the anti-ignition test simulating match flame, that is, the anti-ignition characteristics should meet the requirements of GB 17927.2-2011. Because mattresses used in public places are often used in places with high population density and complex buildings, once a fire occurs, it will inevitably cause serious personal and property losses, so the requirements for flame retardant performance are also high.

For mattress products to pass this requirement, the mattress fabric must be flame retardant, or the fabric and bedding must also be flame retardant. 2.3 Formaldehyde emission Formaldehyde is a highly toxic and harmful substance. Long-term use of mattresses with excessive formaldehyde emission will cause greater harm to the human body. As a bedding for people to sleep for a long time, the control of formaldehyde emission from mattresses is particularly important.

The formaldehyde of the spring soft mattress comes from the textile fabrics, brown pads, etc. used. There are two main reasons for the excessive release of formaldehyde from the mattress: (1) The mattress textile fabric contains formaldehyde. In the production process of fabrics, dyes, anti-wrinkle agents, preservatives and other auxiliaries are used for finishing. If these auxiliaries contain formaldehyde, it is likely to cause the formaldehyde to exceed the standard; (2) The chemical fiber felt, natural coconut palm or natural Materials such as mountain palm and foamed plastics do not contain formaldehyde, but in order to increase the strength and hardness of the materials, some companies use a large number of formaldehyde-containing adhesives in the production process, resulting in serious formaldehyde exceeding the standard. Although there are already formaldehyde-free adhesives, the prices are generally high, and most raw material manufacturers will not use them.
