Because most of the mid-to-high-end car chassis felt on the current market are made of plush, which is not easy to clean and wear-resistant, has poor elasticity recovery, and is expensive. The functions and characteristics of car floor mats (the difference between good and bad car floor mats): better wear resistance and elasticity recovery than the original car felt, anti-static, and has a certain flame retardant property. The composition of car floor mats: consists of two layers, the top layer and the bottom layer. The materials for the top layer fall into three major categories: linen, synthetic fiber, and wool; there is also a type that is blended. Among synthetic fibers, there are two types: PP (i.e., polypropylene and acrylic) and nylon (also known as caprolactam). The forms of various top layer materials (distinguishing methods: visually): linen is made into a curled form (wavy curls); for example, Boqiao car floor mats are made into bent yarn form; wool is made into flat hair form; for example, Yama car floor mats are made into high-cut (flat) low-wear form; there is also one type that is purely handmade. Methods to distinguish various top layer materials: burn them - linen produces a bright flame, while others do not (wool turns to ash, synthetic fibers coagulate into lumps). There are two types of bottom layer materials: PVC (plastic) and rubber. Distinguishing between PVC and rubber: flexibility, wear resistance, elasticity, and slip resistance (rubber is generally better than PVC). Another identification method is by color: PVC is usually black, such as Chi Rabbit Ma car floor mats, while rubber is usually colorful. In terms of smell, pure rubber has a strong odor, while PVC is less so. PVC hardens according to weather changes. Other: the purity of PVC can be distinguished by its pattern; the clearer the pattern, the higher the purity and the better the slip resistance; slip resistance also depends on the thickness and weight of the bottom layer material and the shape it is made into (such as adding nails). Generally, the top layer materials from factories are processed by professional factories and brought back, with specifications of 1.2 meters, 2 meters, and 4 meters; the size of the specifications depends on the quality of the equipment at the foot mat factory. Environmental friendliness of materials; lifespan, washing precautions. Identifying the quality of car floor mats can be done by checking the stitching edges and the smoothness of the top layer material. Various manufacturers purchase PVC powder back for processing. The shape of the bottom layer material also relates to slip resistance. For more information, please visit: http://www.21ctm.net
