Classification by carpet composition
Wool carpet
New Zealand wool, domestic wool, British high-quality four-star wool, Australian wool
Nylon carpet
DuPont nylon, Shouno nylon, BASF nylon, 6.6 nylon — its yarn is 98% nylon and 2% carbon polymer (conductive yarn) Chemical fiber carpet (P.P) polypropylene fiber, polyester, acrylic, polypropylene, imported PP needs heat-setting treatment.
Classification by weaving process
Hand-woven carpet
Hand woven carpet, fine workmanship, colorful patterns, mostly used for pure wool carpet.
Non-woven carpet
Carpet weaving type non-woven carpet adopts non-woven manufacturing technology, i.e. the raw material is made directly into fabric by weaving method without the traditional spinning process. Therefore, non-woven carpets are short wool carpets without warp and weft weaving, such as needle-punched carpets and bonded carpets. This kind of carpet glues the pile on the backing of rubber or hemp backing. The process is simple and the cost is low, but the carpet is thin, the footing is poor, and the durability and elasticity are also rented poor.
Tufted carpet
Tufted carpet is woven by tufting method, divided into flat pile carpet and loop pile carpet. Loop pile carpet does not cut the pile circle in the weave, the surface is one circle after another, the pile height is 5~10mm. After cut pile treatment, it is flat pile carpet, the pile height is mostly 7~10mm.
Carpet raw material comparison
Wool
Good elasticity, not easy to pollution, deformation, wear and tear, good heat insulation, easy to corrosion, insects, higher price.
Nylon (also called nylon fiber)
Wear-resistant, easy to clean, no corrosion, no insects, no mildew, but easy to deformation, easy to generate static electricity, will be partially dissolved in case of fire.
Polyester (also known as poly enzyme fiber)
Abrasion resistance is second only to nylon, heat-resistant, sun-resistant, not moldy, not insects. Dyeing is difficult.
Polypropylene (also known as polypropylene fiber)
Light weight, good elasticity, high strength, abundant raw materials, low production cost.
Acrylamide (also known as polyethylene wax fiber)
Soft, warm, good elasticity, the elastic recovery force in the low elongation range is close to that of wool, lighter than wool, not moldy, not corrosive, not moth-eaten, the disadvantage is poor abrasion resistance.
Identification by carpet quality
Weave density
The standard is that the higher the number of warp threads in each 0.3048 square meter carpet, the better the quality, generally the carpet for family use is 90~150 channels, the carpet used in high-grade decoration should be more than 200 channels, even up to 400 channels.
Abrasion resistance
The number of times the carpet needs to be exposed to the backing by wear and tear under fixed pressure The wear resistance of the carpet is related to the variety of raw materials and the thickness of the carpet weave, the thicker the more wear resistance.
Resilience
The thickness loss rate of the carpet under dynamic load is expressed, that is, the carpet is pressurized, and after a certain time, the pressure is removed and the thickness difference between the carpet and the unpressurized carpet is measured, and the rebound ability of the pile on the surface of the carpet is favored.
The thicker and smaller the difference, the better the resilience. The resilience is tested as follows: wool, eyeliner, nylon, polypropylene. Of course, due to different origins, different levels of technology, especially the emergence of many reborn products, this sort will also change.
Electrostatic properties
The carpet charged and discharged, measured by the carpet surface resistance and static voltage, is generally related to the electrical conductivity of the fiber itself The chemical fiber carpets produced at present are treated and will have no effect on the use.
Flame resistance
For chemical fiber carpet, if the burning time is within 12 minutes and the diameter of the burning area is within 17.96 cm, the flame resistance is qualified. In comparison, polypropylene carpet is poorer in flame-resistance, while other carpets are not much related to flame-resistance index. Of course, in addition to flame-resistance, we should also pay attention to the problem that chemical fiber carpet is easy to produce damage gas after burning.
The choice of carpet quality
The quality of carpet products is mainly determined by the test data, but also by some simple empirical selection methods.
Pile density of carpet
You can touch the carpet by hand, the pile head quality of its products is high, the density of the carpet surface is rich, so the carpet is good elasticity, pedal resistance, wear resistance, comfortable and durable.
Here, we remind consumers not to take the method of picking long pile to select carpet, which looks good on the surface, but the density of pile head is loose, and the pile head is easy to fall down and deform, so the carpet is not resistant to stepping, easy to lose the unique performance of carpet, not durable.
According to the different laying occasions, choose the carpet of different manufacturing process. The carpet with high quality and density of pile head per unit area, otherwise the sparse pile head will cause the change of flower pattern and pile head fall.
Color fastness
Colorful carpet, soft texture, beautiful and generous.
When choosing carpet, you can rub your hand or test cloth on the carpet surface several times to see if there is color sticking on your hand or test cloth. If there is color sticking, it means that the color fastness of the product is not good, which will cause the carpet to change color and lose color easily in laying and use, and affect the beautiful effect of the carpet in laying and use.
Carpet backing peeling strength
The back of the tufted carpet has a grid backing with latex, and the peeling strength of the backing according to the standard is ≥25N. Consumers can gently tear the backing by hand to see the degree of adhesion when selecting this type of carpet, if the adhesion is not high, the backing is easy to separate from the carpet body, so the carpet is not durable.
Look at the quality of appearance
Consumers in the selection of carpet, to check whether the carpet surface is flat, whether the carpet edge is straight, whether there are defects, oil spots, color difference, especially when buying tufted carpet to check whether the carpet backing off, seepage of glue and other phenomena, to avoid the carpet in the use of paving drum, inequality, and lose comfortable, beautiful effect.
