Sharkskin

Sharkskin is a smooth worsted fabric with a soft texture and a two-toned woven appearance.

Lightweight and wrinkle-free, sharkskin is ideal for curtains, tablecloths and napkins. Sharkskin fabric is popular for both men’s and women’s worsted suits, light winter jackets and coats. Sharkskin is commonly used as a liner in diving suits and wetsuits.

Typically, sharkskin fabric is made with the use of acetate or as a blend of the two, and its two-toned woven appearance is achieved by basketweaving, thereby creating a pattern in which the colored threads run diagonal to the white fibers. Because both fabric options already have a relatively smooth texture, the combination results in the finish for which sharkskin fabric is known.

The finest "natural sharkskin" fabric has been historically made of all natural fibers, being some mixture of mohair, wool and silk.

More expensive variations, often demarcated by fabric content labels bearing "Golden Fleece", "Royal" or the like, indicate an extremely rare and costly "sharkskin" of yester-year. Those fabrics, produced in small quantities, were manufactured in South America (Peru and Argentina: by transplanted German/Italian weavers) from the 1950s and 60s and are known to include in some instances even small percentages of vicuna, guanaco or alpaca in such blends: inclusion of silk (then a very costly fiber) was even more common among the "natural sharkskins". Whereas, "artificial sharkskin", a much less costly substitute, is a fabric variant that is more often found from that period and can contain synthesized or synthetic fibers that were developed contemporary to those eras.

Artificial sharkskin variants used for suiting first appeared in the 1950s and rapidly garnered world-wide appeal in artificial sharkskin (costing much less than its "natural" counterpart: which most consumers were not aware existed, so far out of their price range it remained), attaining broad popularity in the early 1960s, followed by brief fashion resurgences in the mid-1980s, mid-1990s and enjoying occasional fashion popularity throughout the 2000s: its variations often contain some wool percentage blend. More recently, such artificial sharkskin fabrics have undergone technological improvements and have attained new desirability, even among "fabric purists" who would have conventionally rejected out-of-hand any "artificial sharkskin" substitutes for the real item containing a majority percentage of mohair.
