Performance requirements for carpets, doormats and kitchen rugs
Carpet is not only a kind of paving material, but also a kind of decorative fabric. Therefore, the performance requirements of carpet fabric have both these two aspects.
The carpet needs to bear a lot of pressure. The pressure of furniture and utensils and the trampling of people when they move frequently make the fiber in a fatigue state. Therefore, the carpet is required to have good wear-resistant and pressure resistant properties. The pile should have good resilience and high density, so it is not easy to fall down. Most of the dust from daily carpet cleaning is absorbed by electric machines such as vacuum cleaners. Therefore, the fiber and organizational structure of the carpet need to have a certain fastness, which is not easy to remove lint.
Carpets are exposed to the air for a long time, and their color will be affected due to photosynthesis, especially sunlight. Therefore, there are certain standards and requirements in terms of fiber color fastness.
（2） Warmth retention
The warm keeping performance of carpet is determined by its thickness, density and the type of fiber used for suede. The carpet is thick and soft with numerous tufts or loops. The pile and loops are long and dense. The carpet with good fluffy degree is especially warm. The warmth retention of synthetic fiber is generally better than that of natural fiber, and wool is better than silk and hemp. In addition, the warmth retention of the carpet is also closely related to whether there is a pad under the carpet and the structure of the pad, so the use of the pad can enhance the warmth retention of the carpet.
The comfort of carpet mainly refers to the foot comfort when walking. This includes fiber properties, softness, elasticity and fullness of suede. Natural fiber is better than synthetic fiber in terms of foot comfort, especially wool fiber, which is soft and elastic, comfortable and light. Chemical fiber carpets generally have the defect of sluggish foot feeling. The carpet with pile height of 10-30mm has good softness and elasticity, plump without losing strength, and comfortable walking feeling.
The pile surface is too short. Although it is durable and easy to walk, it lacks softness and elasticity, and the foot feel is not good.
（4）Sound absorption and sound insulation
The carpet shall have good sound absorption and sound insulation performance, which requires careful selection when determining the fiber raw materials, carpet surface thickness and density, and considering the sound absorption rate, so as to meet the sound absorption and sound insulation performance requirements of different environments. Theatres, large conference halls and other places attach great importance to sound quality, and strive to avoid noise intrusion. They have high requirements on the sound absorption and sound insulation performance of carpets, which can be properly mastered for general household use.
When the carpet is used, it is exposed in a large area. People often walk on it and have a rest. During this period, dust and debris are very easy to stain the carpet. Therefore, the carpet is required to have the performance of not easy pollution and easy decontamination and cleaning. Carpets used in family rooms need to be dirt resistant and convenient for daily cleaning.
Carpets also need to have good antibacterial, mildew resistant and moth resistant properties. In particular, carpets made of wool fiber are easily mothed when used in high temperature and humidity environments. Therefore, moth proof treatment is required to ensure good performance and service life of carpets.
The safety of carpet includes antistatic property and flame retardancy.
When people walk on the carpet, the friction between the sole and the suede is easy to generate static electricity. Once the fingers contact with metal objects, there will be a slight electric shock. Static electricity also makes the pile on the carpet surface easy to be stained with dust and produce the feeling of wrapping the feet, which is particularly obvious for chemical fiber carpets. For this reason, some anti-static methods are being studied, such as mixing metal fiber, carbon and conductive fiber materials into pile fiber, or mixing extremely fine carbon black into the glue on the back of carpet, so as to prevent and reduce the generation of static electricity.
Modern carpets need to be flame retardant, low smoke and no toxic gas when burning. At present, wool carpets have good flame retardancy, while carpets made of synthetic fibers are very easy to burn and melt. The method to improve the flame retardant performance of synthetic fiber carpet is to react with flame retardant copolymer in the polymer stage of synthetic fiber production, and then spin. This method is widely used in acrylic fiber production. Flame retardant is added in the polymer stage and then spun. This method is widely used in polyester fiber production. The above methods can improve the flame retardant performance of synthetic fiber carpet. 3 moves to easily select carpets
Experts said that a good carpet should first be able to well realize its functions, such as comfort, water absorption, sand scraping, etc., which is the fundamental standard to measure the quality of the floor mat. Secondly, good carpets should be easy to maintain, do not need to spend too much human and material resources, should also be durable and environmentally friendly, and the designs and colors can be kept beautiful for a long time.
The most direct way is to touch the surface of the floor mat with your hand to see if it has hair loss, color difference, and pungent smell. Carpets of good quality, especially synthetic carpets, should be odor free.
If you choose a carpet that emphasizes the effect of water absorption, you can wet your hands, press it on the carpet, and then see if there is water residue on your hands. If there is no residue, it is proved that it has good water absorption.
If the doormat is selected, its sand scraping function can be tested. The specific methods are:
After stepping on the sand or dirt with both feet, walk on the floor mat, and then step on the white paper. Then observe whether there is any residual dirt on the white paper. If there is any residual dirt, it indicates that the decontamination function of the floor mat is poor. This test can be done several times to prove the effect of the mat after continuous use.
Carpet materials mainly include wool, propylene, nylon, hemp and blended carpets. The following are the most suitable for families: 1. before wool could not produce synthetic fiber, most carpets were woven with wool. Wool belongs to animal fiber, which is tubular, so it has respiratory function. When there is much moisture in the room, the wool can absorb moisture; When the room is dry, it can release water. This property not only enables the wool carpet to adjust the indoor dry humidity, prevent combustion, but also prevent electrification in the indoor air. The surface of wool is scaly, which has good moisture absorption and water repellent function, so it is difficult for wool to be polluted. In addition, the wool is spirally curled, elastic and difficult to stick together. Wool is also easy to dye into various colors and has a long service life. But the price of woolen carpets is higher.
- propylene is a synthetic fiber, lighter than wool, with good moisturizing performance. It feels like wool and is not easy to burn after flame retardant treatment. Acrylic fiber is less elastic than wool, but better than nylon. Acrylic carpet is also acid and alkali resistant and corrosion resistant, and its price is also lower than that of wool carpet. Therefore, many families now use acrylic carpets. 3. nylon carpet woven from nylon has good durability, strong corrosion resistance, mold resistance, moth resistance, acid and alkali resistance, tensile resistance, twists and turns resistance, especially good wear resistance and low price. It is more suitable to be paved in corridors, stairs, living rooms, offices and other places where people move frequently. The disadvantage of nylon carpet is that it is easy to generate static electricity, not heat-resistant, easy to burn and easy to pollute.
