Silk is a natural fiber produced by certain insects, primarily silkworms, during part of the cocooning process. The material has been harvested for use as a textile for thousands of years. Spider silk, on the other hand, is produced by spiders for building their webs. It is notoriously strong - on a weight-to-weight basis, spider silk is stronger than steel.

Both silk and spider silk have unique properties, which can make them valuable to multiple industries. A Texture Analyzer allows researchers to quantify their physical characteristics, enabling them to compare and contrast materials to determine which material best suits a specific purpose, and to come up with new uses.

Silk and spider silk each have complex molecular structures. While silk is primarily made of two proteins, fibroin and sericin, spider silk consists of repetitive protein sequences, arranged in such a fashion to cause its incredible strength and elasticity.

Silk can be evaluated by using a Texture Analyzer to apply controlled pressure or tension to indicate its ability to resist deformation under stress. This helps us understand silk’s mechanical properties and create new uses for the fabric.

Known for its ability to stretch several times its original length before breaking, spider silk is being explored for various industries and applications. A Texture Analyzer can be used to gradually stretch the material until it reaches its breaking point. The resulting stress-strain curve determines spider silk’s tensile strength, toughness, and maximum elongation.

The versatility of these materials means they have a wide range of uses, from bandage and wound care to body armor. Texture Analyzers can help researchers develop these uses, create and test synthetic alternatives, and explore new concepts.
