Polyurethane Textile Composition for Durable Wrinkle Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Textile products such as garments and linens often wrinkle due to use and cleaning, and existing methods like ironing or steaming provide temporary relief but are not durable, leading to recurring wrinkles.
Innovation Solution
A textile benefit composition comprising polyurethane, a cross-linking agent, and a carrier, applied through processes like spraying or soaking, which imparts durable anti-wrinkle properties to treated textiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If ironing or steaming is used to reduce wrinkles, then the textile appearance is improved temporarily, but the anti-wrinkle effect is not durable and wrinkles reappear during cleaning and storage
Solution Approach 1:
The patent applies a composition containing polyurethane and cross-linking agent to the textile before final use, creating permanent chemical bonds that prevent wrinkle formation in advance. This preliminary chemical treatment replaces temporary mechanical ironing or steaming, providing lasting anti-wrinkle protection that survives cleaning and storage cycles.
Solution Approach 2:
The invention uses a composite system combining polyurethane polymer with cross-linking agents to create a durable anti-wrinkle coating on textiles. The cross-linked polyurethane network provides both the shape-maintaining properties and the durability needed to withstand repeated cleaning and storage, overcoming the limitations of single-material approaches.
2Duration of action of stationary object
If a polyurethane and cross-linking agent composition is applied to textile, then durable anti-wrinkle properties are achieved, but the composition complexity increases
Solution Approach 1:
The polyurethane composition serves multiple functions simultaneously: it acts as a binder, cross-links to form a durable network, provides wrinkle resistance, and maintains flexibility. This multi-functionality reduces the need for separate treatment steps or additional components, managing composition complexity while achieving durable anti-wrinkle effects.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The composition effectively reduces wrinkle formation and durability, maintaining the anti-wrinkle properties even after repeated cleaning and use, enhancing the longevity of wrinkle-free appearance in textile products.
