"单面针织物" can be translated as "single-faced knitted fabric" or more commonly in the textile industry as "single jersey fabric".
"Single-faced" emphasizes that the fabric has only one visible or textured side.
"Knitted fabric" directly refers to the type of fabric produced by knitting.
"Single jersey" is a specific and widely recognized term in the textile and garment industry for this type of fabric, characterized by its plain, single-layer structure with a distinct right (face) and wrong (back) side.
In most contexts, especially within the textile and fashion industries, "single jersey fabric" would be the preferred and most accurate translation.
