Abstract
The invention relates to a fabric having both stab resistant and anti-ballistic properties. The fabric is made of yarn of a weight greater than about 500 dtex, and the fabric has a minimum shrinkage factor of at least about 1% achieved through a densification treatment. The invention further relates to a method of producing a such a fabric having the steps of agitating a fabric made of a yarn of a weight greater than about 500 dtex, substantially removing a spin finish from the fabric before, during or after the agitating step, and drying the fabric.
