Solution Overview
Problem
Conventional softening agents for textiles with washing durability are highly combustible and exhibit poor flame retardancy due to their primary silicone component.
Innovation Solution
A softening agent for textiles comprising a non-silicone compound (A) with a polyoxyalkylene chain and a crosslinking agent (B), which react to form a durable polymer coating on fibers, improving washing durability without compromising flame retardancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If a silicone component is used as a primary component in a softening agent, then washing durability is improved, but flame retardancy deteriorates
Solution Approach 1:
The patent changes the chemical composition parameters by replacing the primary silicone component with a polyoxyalkylene compound containing reactive functional groups. This parameter change allows the softening agent to maintain washing durability through crosslinking while improving flame retardancy by eliminating highly combustible silicone
Solution Approach 2:
The patent creates a composite softening agent system combining a polyoxyalkylene compound (compound A) with a crosslinking agent (compound B). This composite approach enables the formation of crosslinked polymer coatings that provide both washing durability and flame retardancy, resolving the contradiction between these two properties
2Duration of action of stationary object
If a crosslinked polymer coating is formed on fibers, then washing durability is improved, but the complexity of the manufacturing process increases
Solution Approach 1:
The patent applies preliminary action by pre-equipping the polyoxyalkylene compound (compound A) with reactive functional groups before application. This allows the crosslinking reaction to occur in-situ on the fiber surface during or after softening agent application, forming the crosslinked coating without requiring separate complex manufacturing steps
Solution Approach 2:
The patent uses a crosslinking agent (compound B) as an intermediary that facilitates the formation of crosslinked structures. This intermediary enables the polyoxyalkylene compound to form durable coatings through crosslinking reactions, simplifying the overall process compared to pre-synthesized crosslinked polymers
