[{"id": 1, "text": "Characteristics of polyester-cotton blends: They combine the advantages of polyester and cotton fabrics, exhibiting good elasticity and wear resistance in both dry and wet conditions. They are dimensionally stable, with low shrinkage, and possess characteristics such as crispness, wrinkle resistance, easy washing, and quick drying. However, they cannot withstand high-temperature ironing or boiling water immersion. Disadvantages of polyester-cotton blends: Polyester fibers, a component of polyester-cotton blends, are hydrophobic and have a strong affinity for oil stains, easily absorbing them. They also tend to generate static electricity during wear, attracting dust and becoming difficult to clean. Furthermore, they cannot withstand high-temperature ironing or boiling water immersion. Polyester-cotton blends are synthetic fibers and are not biodegradable."}

Knit denim is a type of denim fabric. It is made using bundled dyed indigo, blue-black, sulfur black, etc., knitted tubular yarns and undyed white cotton yarns and other functional yarns, which are woven on a circular knitting machine using different weaving methods or jacquard techniques and special processes to produce garments with a washed-out effect. The process flow is as follows: yarn dyeing (using denim indigo dye, the yarn tubes are unwound into twisted yarns and dyed at normal temperature and pressure) - winding - weaving - unweaving - finishing (through specific types of washing, stone washing and brushing, etc.). Knit denim has better elasticity than woven fabric, and currently the market is popular
