What This Patent Covers

This patent protects a novel method for preparing cocoons for reeling, specifically covering the combination of multiple steps: contact with organic solvents/acids, their removal, and subsequent water permeation using specific techniques like reduced pressure or low-temperature reduced pressure. The claims are robust and difficult to circumvent, having successfully overcome four prior art references during examination, indicating a strong and stable intellectual property right.

Competitive White Space

This patent primarily covers the cocoon preparation method. White space exists in novel raw silk reeling machinery, advanced post-processing techniques for the raw silk, or innovative end-product formulations utilizing the extracted silk proteins.

ROI Calculation Logic

For a company producing 100 tons of raw silk annually, this technology could reduce energy costs by 30% (e.g., $10K (AI est.) from an estimated $33.5K baseline) and waste treatment costs for alkaline solutions by 50% (e.g., $10K (AI est.) from an estimated $20K baseline). Additionally, shortened preparation time could improve labor efficiency by 20%, saving approximately $13.5K (AI est.) from an estimated $66.5K labor cost for two operators. This totals over $33.5K (AI est.) in annual economic benefits.

Speed to Market
6× faster than in-house development
This technology, developed by a national research institute, has completed fundamental research and established key technical elements. Core technologies, such as the selection of specific organic solvents/acids and permeation methods, have already been demonstrated. This allows licensees to start from the validation phase rather than from scratch, potentially shortening time-to-market by approximately 2.5 years compared to in-house development, enabling earlier business expansion.

Integration Roadmap — Estimated 15-Month Deployment
Phase 1: Technical Evaluation & Requirements Definition
Duration: 3 months
Evaluate the feasibility of implementing this technology, identify compatibility with existing production facilities, and determine necessary modifications. Define detailed requirements based on target raw silk quality and production volume.
Phase 2: Prototype Development & Pilot Testing
Duration: 6 months
Based on defined requirements, construct a small-scale pilot facility and conduct demonstration experiments using this cocoon preparation technology. Collect data on quality, efficiency, and cost, then optimize the process.
Phase 3: Production Line Implementation & Optimization
Duration: 6 months
Based on pilot test results, proceed with the design and implementation for full-scale production lines. Continuously analyze operational data post-implementation to further optimize production efficiency and quality.
Technical Feasibility
The patent claims suggest that contact with organic solvents/acids and permeation processes (reduced pressure, low-temperature reduced pressure, cocoon boiling cooling, and touch-steaming methods) can be achieved by adapting existing chemical processing equipment and vacuum/temperature control systems. This indicates high technical feasibility, as it could be implemented with minimal new equipment investment, primarily through add-ons or process modifications to existing manufacturing lines.
Success Scenario
Upon adopting this technology, companies could potentially reduce combined energy and waste treatment costs from conventional cocoon boiling processes by 20% annually. This could lower manufacturing costs and enhance market competitiveness. Furthermore, the ability to stably supply high-quality raw silk may lead to the expansion of high-value product lines and the acquisition of new customers.
