Recently renovated, watching the sofa found that each family is not the same, the fillings are varied, there are high-density cotton, low-density cotton, nine-hole cotton, seven-hole cotton, doll cotton, down, in short, quite a lot. So what do you usually use for sofa filling?
The sofa, a multi-seat with cushions, has a wide variety of styles and can be seen everywhere in modern life. It is a kind of soft furniture. When consumers buy sofas, they usually choose from color styles, exterior materials, interior frames, internal fillers, and other details. I wonder if everyone knows what the sofa fillers are all about? Today we will reveal the material of the sofa padding.
The sofa is a kind of upholstered furniture that has become an indispensable part of our lives. The earliest origins of the sofa can be traced back to ancient Egypt around 2000 BC, but the real soft-cloth sofa appeared from the end of the sixteenth century to the beginning of the seventeenth century. At that time, due to technical limitations, the sofa filler mainly used natural elastic materials such as horsehair, bird feathers, and plant fluff. The outer material was made of velvet, embroidery, etc., thereby forming a soft human contact surface. The original sofa prototype.
In general, there are three main materials used in modern sofa fillings, down, artificial cotton, and sponge. The down material is believed to be familiar to everyone. The down jacket worn in winter is made up of down. Down has a very good fluffiness, it is used to make a sofa padding, its sitting feel is more comfortable than a normal sofa, and it is not easily deformed after long-term use, so the service life is longer. However, the sofa of this down filling has a slower rebound and a higher production cost, so the down filling is usually used with a sponge for the production of a high-grade sofa, or for making a cushion.
Sponge is the most commonly used sofa filler material in modern times. It is also called soft polyurethane foam. It is mainly divided into three categories: conventional sponge, high resilience sponge and chaotic sponge. The quality of the sponge is in turn After incrementing. Conventional sponge is a sponge made of conventional polyether and TDI, which has high resilience, softness and gas permeability. High resilience sponge is produced by reactive polyphosphorus and TDI, and its mechanical properties and resilience are more conventional. The sponge is better, the compression load is large, the flame resistance and the gas permeability are better; the chaotic sponge is a kind of sponge with different internal diameters and similar to natural seaweed, which has the best rebound resilience and has extreme compression and rebound. Good cushioning.
Artificial cotton should be regarded as a kind of material used in modern society. Using artificial cotton to make sofa filling, its softness is very good, and the feeling of sitting on it will be extremely comfortable. However, the material of this kind of rayon has relatively poor mechanical properties and low compressive load capacity. It is only suitable for the internal filling of sofa cushions. Few merchants use separate rayon for sofa filling. In most cases, the combination of rayon and sponge is used.
