What This Patent Covers

This patent broadly protects a novel method for preparing cocoons for reeling, distinct from conventional techniques, by using organic solvents/acids for low-temperature treatment followed by a water penetration step. The claims were established after overcoming two office actions through precise arguments and amendments, indicating a robust and stable intellectual property right.

Competitive White Space

This patent focuses on cocoon preparation. White space could include advanced post-processing of silk fibers (e.g., functionalization, dyeing methods), novel weaving or knitting techniques, or integration with smart textile technologies.

ROI Calculation Logic

In conventional degumming, assuming annual energy costs of ~$33.5K (AI est.), chemical costs of ~$20K (AI est.), and labor costs for two operators at ~$133.5K (AI est.), this technology could reduce energy costs by 50% (~$16.5K saved, AI est.), chemical costs by 80% (~$16K saved, AI est.), and improve productivity by 20% (equivalent to ~$26.5K in labor efficiency, AI est.) due to reduced processing time. This projects total direct annual cost savings of approximately ~$59K (AI est.). Additionally, higher product quality could lead to increased unit prices.

Speed to Market
6× faster than in-house development
If developing a similar novel degumming process in-house from scratch, it could take approximately 3 years from basic research to practical application. However, this technology is already patented, with its core technical concept and process established. This allows adopting companies to focus solely on verifying compatibility with existing equipment and optimizing the process, potentially reducing time to market to approximately 6 months, enabling rapid business expansion.

Integration Roadmap — Estimated 28-Month Deployment
Phase 1: Technology Evaluation & Basic Validation
Duration: 4 months
Assess compatibility with the licensee's existing cocoon raw materials and conduct basic parameter validation, including selection of organic solvents/acids and optimization of concentration and treatment time.
Phase 2: Pilot Line Setup & Optimization
Duration: 9 months
Establish a small-scale pilot facility to conduct demonstration experiments under actual production conditions. Optimize processing parameters, evaluate quality, and improve yield.
Phase 3: Full-Scale Implementation & Production Expansion
Duration: 15 months
Based on pilot line results, proceed with full-scale integration of the technology into existing production lines. Establish production systems, begin supplying products to the market, and gradually expand production capacity.
Technical Feasibility
This technology primarily involves a contact step where cocoons are exposed to organic solvents/acids, followed by a water penetration step. This suggests applicability to existing wet processing equipment and chemical treatment facilities in textile factories. The simple process structure described in the patent claims indicates high technical feasibility for integration with minimal large-scale capital investment, potentially through modifications or minor additions to existing equipment.
