Embodiment approach

[0072] figure 2 Shows how a manufacturing process 10 of a reinforced protein material which is silk fiber 12 can be inserted into a standard manufacturing process 14 of a common cocoon 16 , meaning a cocoon comprising natural silk 18 , in a conventional and cost-effective manner. The silkworm 22 is stimulated 24 in order to produce the reinforced protein material 12 . The resulting reinforced cocoon 20 comprising the reinforcing protein material 12 is processed using the same standard manufacturing process 14 as the normal cocoon 16 comprising natural silk 18 . Thus, upon completion of the same standard manufacturing process 14 that is used to conventionally manufacture 28 natural silk 18 , a reinforced protein material 12 is obtained 26 .

[0073] image 3 The effect of stimulus 24 on silkworm 32 in this embodiment is illustrated. A silkworm 32 is placed in a compartment 36 belonging to a compartment array 38 . Stimulus 24 , in this embodiment an electric field ass...

Abstract

The invention provides an enhanced silk fiber rivaling spider silk in mechanical performance, in combination with a very low-cost method for producing it from the usual silkworms. The method provides for the simple application of an electric field which results in an enhancement of over 40% in the strength, and of 200% in the breaking energy with respect to ordinary silkworm silk. The critical elasticity is enhanced to the level of the dragline spider silk. The provided enhanced silk protein material has the same protein primary structure, fiber diameter and length of the customary silk. The method of formation offers the following advantages in comparison to other methods available in the prior art. Industrial scale production can be readily and cost-effectively achieved, given the wide-range availability of silkworms. The provided method relies largely on the present standard production processes of silkworm silk, and hence a low level of investment is required. Since no additional chemicals are required, the provided method is environmentally friendly.

Description

[0001] cross reference [0002] This application claims the benefit of USPTO Application Serial No. 60 / 843,999. technical field [0003] The present invention relates to a proteinaceous material providing improved properties, such as protein fibers, and in particular to a reinforcing silk fiber providing improved mechanical properties and a method of forming the same. Background technique [0004] Natural proteinaceous materials such as silk fibers produced by invertebrate species include secretions of fibrous proteins. Various methods have therefore been further proposed to improve the mechanical properties of silk protein materials. These attempts have the drawback of producing silk protein material expensively, in inconvenient forms, or in commercially unattractive quantities. Generally, the prior art has focused on the various reeling protocols that pull the silk fiber out of the animal or otherwise forcefully as it is spun externally into fibers. For example, silkwor...
