Moisturizing fabric material, use thereof in moisturizing bras, and method of manufacture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bras fail to effectively retain moisturizers on the fabric during washing and may cause fabric discoloration due to chemical bonding agents, and temperature control is crucial for proper bonding.
Innovation Solution
A moisturizing fabric material is developed using a formula comprising plant oil, plant extract, and emulsifier, bonded to polymeric fabric using a cyclodextrin compound at temperatures above 180°C, ensuring the moisturizer is released to the skin while remaining attached during washing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a chemical bonding agent is used to fix moisturizer to fabric, then the moisturizer is retained during washing, but the fabric may turn yellow causing unpleasing aesthetics
Solution Approach 1:
The patent uses cyclodextrin compounds as intermediary bonding agents that chemically bond moisturizers to fabric through host-guest inclusion complexes. The cyclodextrin forms a bridge between the moisturizer (guest) and fabric (host), providing strong retention during washing while the natural cyclic structure of cyclodextrin does not cause fabric yellowing like traditional chemical bonding agents
Solution Approach 2:
The patent controls the bonding process by heating the fabric-moisturizer-cyclodextrin mixture to temperatures above 180°C. This temperature parameter change activates the chemical bonding between cyclodextrin and fabric while ensuring proper fixation. The controlled thermal processing achieves reliable moisturizer retention without causing fabric discoloration that would occur with uncontrolled heating
2Reliability
If the fabric temperature is increased above 180°C for proper bonding, then the bonding between moisturizer, chemical, and fabric is ensured, but excessive temperature may cause fabric damage
Solution Approach 1:
The patent specifies heating the fabric-moisturizer-cyclodextrin mixture to temperatures above 180°C to activate and ensure proper chemical bonding. This controlled temperature parameter change is sufficient to fix the bonding agent to the fabric and ensure moisturizer retention, while the process is designed to complete bonding within a controlled time frame to prevent fabric damage from prolonged exposure
