Coating, knitted, PVC and TPU are suitable for all fabrics. The coating fabric is to treat the ordinary fabric through a special process to form a uniform covering rubber material on its surface, so as to give the traditional fabric more excellent functions, such as flame retardant, wind-proof, waterproof, anti-static and so on. Of course, these composite materials are environmentally friendly and harmless. Specific applications include jackets, handbags, evening gowns, artificial flowers, pajamas, down jackets, car covers, underwear, sportswear, umbrellas, bags, sleeping bags, tents, shower curtains, tablecloths, chair covers and all kinds of high-grade clothing lining.
About us
Anhui Liqiang Textile Technology Co., LTD
Suzhou Lixiong Textile Co., Ltd. is a combination of industry and trade enterprises, as a branch of Wujiang Liming Textile Co., Ltd., the company was initially established in the "silk capital"-Shengze, after the completion of the factory office building to move to Wujiang Pingwang. Mainly to luggage cloth and finished fabric sales. Our company cooperates with a number of well-known domestic luggage companies and includes a number of listed companies. With the expansion of the size of the company, the company's sales are also increasing, and production and sales are gradually closer to internationalization. At the end of 2018, Mr. Zhang Lianmin, chairman of our company, went to Langxi County, Anhui Province, bought 69000㎡ of land to expand production, established Anhui Liqiang Textile Technology Co., Ltd., and began to build the plant at the beginning of 2019. Wholesale Fabrics coated with pu knitted and PVC tpu Suppliers and Factory in China. And in July 2020, 10 standard factories were completed and put into production, and the production capacity was significantly doubled.

Does Fabrics coated with pu knitted and PVC tpu contain harmful chemicals such as phthalates or heavy metals?
Fabrics coated with PU , PVC , and TPU can potentially contain harmful chemicals, depending on the specific formulation and manufacturing processes used. Here are some considerations regarding harmful chemicals:
PVC (Polyvinyl Chloride): Traditional PVC coatings may contain phthalates, which are plasticizers used to make PVC more flexible. Phthalates have raised concerns due to their potential health risks. However, many manufacturers have shifted to producing phthalate-free PVC coatings to address these concerns. When selecting PVC-coated fabrics, look for those labeled as "phthalate-free" or "low-VOC" (Volatile Organic Compounds) to minimize exposure to harmful chemicals.
PU (Polyurethane) and TPU (Thermoplastic Polyurethane): These coatings are generally considered safer alternatives to PVC, as they do not typically contain phthalates. However, it's essential to check with the manufacturer or supplier to ensure that the specific PU or TPU coating used is free from harmful chemicals.
Heavy Metals: Some coatings and pigments used in fabric production can contain heavy metals such as lead or cadmium, which are toxic and pose health risks. Regulatory standards, such as those in the European Union (EU) and the United States, restrict the use of heavy metals in textiles. Reputable manufacturers adhere to these standards to ensure product safety.

Are there potential adhesion or delamination issues using Fabrics coated with pu knitted and PVC tpu?
Fabrics coated with PU (Polyurethane), PVC (Polyvinyl Chloride), and TPU (Thermoplastic Polyurethane) can be susceptible to adhesion and delamination issues under certain conditions. These issues primarily revolve around the bonding between the coating and the fabric substrate. Here are some considerations:
Adhesion Issues:
Surface Preparation: Proper surface preparation is crucial to ensure good adhesion between the coating and the fabric substrate. Any contaminants or residues on the fabric's surface can hinder adhesion. Manufacturers typically clean and treat the fabric surface before applying the coating.
Compatibility: The compatibility of the coating material with the fabric substrate is essential. Incompatibility can lead to poor adhesion. Manufacturers choose coating materials and processes that are well-suited to the specific type of fabric they are working with.
Quality Control: Adhesion issues can arise if there are inconsistencies or defects in the coating application process. Quality control measures, such as monitoring coating thickness and curing conditions, are essential to ensure uniform and reliable adhesion.
Delamination Issues:
Environmental Factors: Extreme environmental conditions, such as exposure to high temperatures, humidity, or UV radiation, can contribute to delamination over time. The choice of coating material and its resistance to environmental factors can impact the durability of the bond.
Mechanical Stress: Delamination can occur when the fabric is subjected to repeated mechanical stress, such as bending, flexing, or stretching. This is particularly relevant for fabrics used in applications like outdoor gear and sports equipment.
Quality of Bond: The quality of the initial bond between the coating and fabric is critical to preventing delamination. Proper bonding methods and quality control during manufacturing help ensure a strong and durable bond.
Age and Use: Over time, especially with frequent use and exposure to harsh conditions, delamination may occur as a result of wear and tear. Choosing fabrics and coatings designed for durability can mitigate this issue.
