Aqueous Binder Formulations That Prevent Textile Spots After Heat Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aqueous binder-containing formulations used in textile treatment often result in spots or stains after thermal treatment due to softener deposits, which affect the aesthetic appeal and fastness properties of the treated substrates.
Innovation Solution
Incorporating specific compounds of the general formula I, where R1 and R3 are selected from C10-C18 alkyl or CO-C19 alkyl/alkenyl, and R2 is C1-C3 alkyl, into the formulations to reduce spots and stains, while maintaining a pleasant hand and good fastness properties like rubfastness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If softeners are added to aqueous binder-containing formulations to improve hand feel, then the substrates have a pleasant hand, but spots or stains are formed during thermal treatment
Solution Approach 1:
The patent removes softeners from the aqueous binder-containing formulations entirely. The formulation is designed to function effectively without softeners, thereby eliminating the source of spots and stains during thermal treatment while maintaining acceptable hand feel through the binder system alone.
Solution Approach 2:
The patent changes the chemical composition parameters of the formulation by excluding softeners. This parameter change prevents the formation of deposits during thermal treatment while the binder system maintains the necessary functional properties for hand feel.
2Ease of operation
If softeners are added to aqueous binder-containing formulations to improve hand feel, then the substrates have a pleasant hand, but deposits are formed in drying cabinets
Solution Approach 1:
The patent extracts softeners from the formulation system, eliminating the source of deposits that form in drying cabinets during thermal treatment. The binder-containing formulation is designed to achieve its function without softeners.
Solution Approach 2:
The patent converts the problem of softener-related deposits into a benefit by designing a softener-free formulation. This eliminates the harmful deposits in drying cabinets while the binder system maintains the necessary performance characteristics.
3Ease of operation
If softeners are added to aqueous binder-containing formulations to improve hand feel, then the substrates have a pleasant hand, but fastness properties are reduced
Solution Approach 1:
The patent removes softeners from the formulation, eliminating the negative impact on fastness properties. The binder system is designed to provide both hand feel and adequate fastness without the interference of softener deposits.
