In terms of industry standards, high-quality Roma fabric must meet several technical specifications. Physically, its bursting strength must be ≥250N, colorfastness (rub/perspiration) must be ≥4, and pH value must be controlled between 4.0 and 7.5. Environmentally, it must be Oeko-Tex Standard 100 certified to ensure that the content of harmful substances such as formaldehyde and azo dyes meets international standards. During production, strict regulations govern everything from raw material selection to finishing processes. For example, environmentally friendly dyes are used for low-temperature dyeing, ensuring color saturation while reducing energy consumption.
When purchasing Roma fabric, pay attention to three key points: First, observe the clarity of the texture; high-quality fabric should have uniform and continuous horizontal stripes without breaks or blurring. Second, test the elastic recovery rate; stretch the fabric laterally to 1.5 times its original length and release; the rebound rate should be ≥90% within 30 seconds. Third, check the colorfastness; rub the fabric surface 10 times with a damp white cloth; there should be no significant color fading. In addition, choose the appropriate weight according to the intended use. For summer clothing, it is recommended to choose a lightweight type with a weight of 220-240g/㎡, while for winter coats, a heavyweight type with a weight of 260-280g/㎡ is recommended.
