The finishing processes that canvas undergo could include treatments that affect its shrink resistance. For example, pre-shrinking treatments are often applied to reduce subsequent shrinkage. Other finishings, like waterproofing or applying fire retardants, can also have an impact on the fabric’s propensity to shrink.
When this fabric meets water, it’s not just a wash—it’s a full-on dance of the fibers. As mentioned, cotton fibers absorb water, expand, and then shrink, but it’s not a one-time show. Repeated exposure to water can cause ongoing shrinkage, reshaping your canvas over time.
Canvas fabric is known for its ability to stretch and loosen over time, especially when exposed to heat. When heated, the fibers of the canvas contract, causing the fabric to tighten and regain its original shape and firmness. This process is similar to the way heat is used to bind bricks and construction materials together, making it an effective method for restoring the integrity and structure of canvas fabric. So the next time your canvas needs a little tightening, remember that a little heat can go a long way in restoring its strength and durability.

Pre-washing canvas fabric, especially in the context of art supplies or DIY projects, is not a common practice, as the canvas is often sold in its raw state.
