Cut Resistance Behaviour of Fibres
By  : Dr. C. Rameshkumar & Dr. N. Anbumani

 cut resistant fabrics are made with polymeric and non polymeric high performance fibres such as high tenacity polyester, nylon, loyotropic polymer fibres, gel spun fibres and thermotropic liquid crystal polymer fibres. New products are also made with core and wrapped yarns by suitable combination of specialty fibres and yarns in different fabric weaves.

There is a continuing need for fabrics that resist cuts and abrasions, which occur when a sharp edge of a knife, a tool having a sharp edge or items having sharp edges are encountered. Cut resistant fabrics are particularly useful for making protective clothing such as gloves used in meat cutting industry and for handling metal/glass articles, in manufacture of sports wear, in automobile upholstery and for packaging materials.

New products are also made with core and wrapped yarns by suitable combination of specialty fibres and yarns in different fabric weaves.

The level of cut resistance provided by the reinforcing yarns depends on the way in which they are incorporated in the textile substrate. With regard to many different fabric manufacturing techniques available, a large number of alternatives for developing cut resistant textiles are feasible.

Cut resistance is the property demonstrated by a material or combination of materials, when a sharp-edged device initiates cut through. In general, there are two types of cut hazards: (1) Sharp edge cuts, such as knife blades and clean edge sheet glass and (2) Abrasive cut hazards; these include rough edge sheet metal, stamped or punched sheet metal, and rough edged sheet glass.
