The trench coat fabric is usually composed of two kinds of fabrics, which are crisp and stylish. However, with the increase of washing and dry cleaning times, the glue used will fail, leading to the problem of fabric delamination and shedding. Because the shrinkage of the upper and lower composite fabrics after washing is inconsistent, it will lead to the phenomenon of fabric wrinkling and foaming. Slight wrinkling and foaming problems can be solved by ironing at high temperature. High temperature ironing can smooth the fabric and reduce wrinkles and bubbles. Before ironing at high temperature, it is necessary to know the suitable temperature range of the fabric to avoid damage or deformation of the fabric. For serious delamination and shedding, it is recommended to seek professional repair or consultation to ensure that the fabric is properly treated and repaired.
