Solution Overview

Problem

Current technologies fail to produce stable and mass-producible textiles blended with collagen and synthetic fibers due to hydrophobicity issues and manufacturing difficulties.

Innovation Solution

A blend composition of polyamide fiber and denatured collagen, where the polyamide fiber accounts for 97-99.9% by weight and denatured collagen for 0.1-3% by weight, with amide groups linked through hydrogen bonds, is developed, allowing for the formation of a stable textile through a method involving caprolactam polymerization and heat denaturation of collagen.

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent creates a composite material blend consisting of polyamide fiber (97-99.9 parts by weight) and denatured collagen (0.1-3 parts by weight). This composite structure combines the hydrophobic properties of polyamide for dehumidifying performance with the hydrophilic properties of collagen for comfort, resolving the contradiction between dehumidifying capability and comfort feeling.

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies preliminary action by pre-denaturing the collagen through heat treatment before blending with polyamide fiber. This pre-processing step transforms the collagen structure in advance, making it more compatible with synthetic fibers and significantly reducing the manufacturing complexity of creating a stable blend textile.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by controlling the heat treatment temperature and duration to denature collagen at specific parameters (heating to appropriate temperature ranges). This parameter control optimizes the collagen structure for blending, making the manufacturing process more feasible and stable for mass production.

Core Design Contradiction:

Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The patent applies parameter changes by optimizing the collagen content within a specific range (0.1-3 parts by weight per 97-99.9 parts polyamide fiber) and controlling the heat treatment parameters. This parameter optimization achieves the desired moisture regain while maintaining manufacturing stability, as the denatured collagen structure prevents aggregation and ensures uniform distribution in the blend.
