The reinforced walls are stronger, limiting further growth

This new growth also reinforces the cell wall by going against the grain of the existing wall.The strengthened wall is more rigid, restricting further growth.That means if the fiber remodels its walls too early,it will be short,and ultimately make rough, weak fabrics.But if cell wall strengthening begins too late,the wall won’t be sturdy enough—producing fibers that are too weak to hold fabrics together well.
