three base steps to choose fabric sofa
1, the structure of the sofa
The current market structure in the sofa on the whole process at:
A, solid wood structure - due to the shortage of timber resources, furniture for the structure of the hard Zamu more scarce, in addition to the Zamu hard to deal with the needs of dry high technology, Mao tenon connection. As a result, real solid wood structure of the sofa are very expensive, and to ask the solid wood species and plant technology. Such structure of the sofa quite scarce.
B, wooden boards - the use of cheap wooden beams and do vertical support, combined with multi-layer composite panels used nail then skeleton structure made of the way. Such low-cost structure of the material used to produce a simple, convenient shape to create efficient, is a widely used technology structure. Shortcomings: complex multi-layer sheet of high formaldehyde content, easy to distribute a large number of non-polluting and smell, a strong deformation of the general damp easy, short life, and so on. In the choice of when to pay attention to the sofa shaking inspection of the structure of the firm, opened the bottom zipper heard a deep breath to hear whether there is a mean, to sit under the gravity response to the feelings of momentum.
C, all-steel welded structure - the general standard to the standard steel pipe in touch with forming the next welding, rust-proof handle. Forming such a process difficult and long working hours, high technical requirements. Advantages: the stability of the structure, strength, environmental protection, long service life. At present, most of Europe to adopt such a structure of the sofa, the sofa is the future development direction. Beijing court only individual brands such structure is ideal for consumer choice.
Sofa to choose the structure of the main points: the three types of structures can be asked (to ask Daogou Yuan sold the structure of the sofa), see (a-kind look at the situation to determine the structure of the second look at the use of the material test), test (try to sit, move the sofa Shaking), smell (odor smell) and other methods to determine the structure of the merits and demerits. In addition, the structure of the surface of the seat is especially important to deal with the main efforts into rubber bandage (a flexible but well short life, and therefore easy for a collapse), flat wood (inelastic, but the difference avian influenza take long life), snake-shaped steel spring (good flexibility Take good sense, long service life, in general the use of steel structure). Structure of the plane is sitting on the sofa by the force of the main site, but also a comfortable sofa and a key part of the length of life, so the focus should be asked and inspection.
2, the sofa filler
The sofa filler There are three main
A. Soft polyurethane foam (commonly known as a sponge)
Sofa-filled sponge for the three major sub-categories
Conventional sponge is a conventional TDI and polyether as the main formation of sponge. Characterized by a good back flexibility, softness and breathability.
High Rebound is a sponge activity and phosphorus-generation TDI as the main body of the sponge, characterized by excellent mechanical properties, better flexibility. Compression load, fire, good air permeability.
Chaos is a cavernous hole by hole size of the algae similar to that of a natural sponge, which is characterized by flexibility, compression, rebound with an excellent time of the buffer.
B. Stuffing down:
So down-filled sofa, sitting comfort and long-term use of small deformation, the disadvantage is the slow rebound, the high cost. In general with high-level sofa with a sponge, or the use of appropriate cushion to do.
C. Man-made cotton stuffing:
Man-made cotton sofa filler, an excellent soft, ride comfort, but the mechanical properties of the poor, small compression load, only to do a cushion.
The sofa filler of choice: According to the different types of filler, use very different. Under normal circumstances, the cloth sofa cushion filler should be 30 kg / m rebound high above the sponge is more appropriate, in the form of block foam used to fill most of the way, the best form of a 30 kg / cubic meter over High-rebound sponge and sponge combination of down-hole arbitrary or superimposed Rayon combined increase comfort and service life. To choose when to ask the type of filler, filler sponge is used to understand the density of the sponge, with feelings of gravity cushion the effect of the rebound, got to sit feeling a sense of comfort and so on. General use of the sponge cushion, the National Institute of Standards 25KG/M3, international standards 35KG/M3. Bottom structure, high-elastic bandage is superior to the structure of the snake spring structure, better than the poor quality bandage bandage structure in the two above-mentioned principle, the European high-level sofa commonly used sandwich structure design.
3, sofa fabric
The cloth fabric sofa products related to the density of long-term use of mechanical wear and tear of life, national standards for the sofa fabric density is greater than the 300D. Most of the use of chemical fiber fabrics or blended fabrics, China’s textile fabrics of cotton fiber is still difficult for the surface of the sofa, as the pure face of shrinking, durability, flexibility to factors such as the use of small cotton cloth sofa fabric .
Sum up: the sofa cloth from the inside to outside inspection step by step, not only judge the merits of style, furniture, sofa, as the highest utilization rate, which is the home of the main components of life, from environmental protection, comfortable, durable, health care point of view of choice , Have a better understanding of some basic common sense, can not be fooled by appearances, both inside and outside to make it value for money.
