NYSID Textiles for Interiors Practice Exam

The Wyzenbeck test measures the durability of upholstery fabrics through a specified number of rubs to determine how well the fabric resists wear over time. For a fabric to be classified as suitable for heavy-duty use in contract environments, it must withstand a significant level of abrasion without showing signs of wear.

In the context of contract fabrics, a rating of 30,000 double rubs indicates that the fabric can handle a considerable amount of use, making it appropriate for commercial settings where heavy use is expected. This level of durability is critical for upholstery in restaurants, offices, and other public spaces where the fabric will endure frequent contact and friction. Fabrics that achieve this rating will typically maintain their aesthetic and functional qualities longer than those with lower rub counts.

Fabrics rated at lower levels, such as 15,000 rubs, are generally considered suitable for residential use but may not provide the long-term durability needed in contract applications. Similarly, while fabrics rated at 50,000 rubs offer even greater durability and may fit into a category of extreme use or specialized commercial contexts, the standard for heavy-duty contract fabric is typically at the 30,000 rub mark. Thus, this benchmark helps textile professionals select appropriate fabrics for specific environments based on
