Linear Polyether Fabric Treatment for Faster Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fabric drying methods require extended times, consuming more energy and resources, and existing fabric treatments do not effectively reduce drying time.
Innovation Solution
A method involving multiple launderings with a composition containing a linear polyether with a weight average molecular weight less than 5000, terminated with -N-(-CH2-CH(OH)-CH2-Cl)2, which is deposited on the fabric to reduce drying time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional drying methods are used, then fabric drying is achieved, but drying time is extended and energy consumption increases
Solution Approach 1:
The invention changes the chemical composition parameters of the fabric surface by applying a polymeric material containing hydrophilic groups (such as poly(oxyalkylene) groups with amino end groups). This modifies the fabric's surface properties to enhance water absorption and evaporation characteristics, thereby reducing drying time and energy consumption without altering the fundamental drying process
2Loss of time
If fabric is laundered multiple times with the composition, then the polyether is deposited on the fabric to reduce drying time, but the laundering process becomes more complex
Solution Approach 1:
The invention applies the polymeric treatment composition during the laundering process itself, specifically during the rinse cycle or as a final rinse. This preliminary action during washing ensures the polymeric material is deposited on the fabric before the drying step, so the drying time reduction effect is already in place without requiring separate treatment steps afterward
Solution Approach 2:
The treatment composition is designed to be integrated into existing laundering processes, serving multiple functions: it acts as a fabric treatment that reduces drying time while being compatible with standard washing and rinsing procedures. The same laundering process that cleans the fabric also deposits the drying-reducing polymeric material
