Detergent Composition for Textile Tensile Strength Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents cause textiles to lose tensile strength and dimensional stability during the washing process, leading to a deterioration in the appearance and shape of textile fabrics over time.
Innovation Solution
A detergent formulation comprising alpha-substituted compounds and alkoxylated polyethyleneimines, specifically alpha-hydroxyoctanal or alpha-hydroxyoctanone, and ethoxylated polyethyleneimines, is used to improve fiber and textile properties, enhancing tensile strength and dimensional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional detergents are used for washing textiles, then cleaning effectiveness is achieved, but tensile strength and dimensional stability of textiles deteriorate over time
Solution Approach 1:
The invention changes the chemical parameters of the detergent by incorporating specific alpha-substituted compounds (formula I) and alkoxylated polyethyleneimines (formula II) with defined molecular weight ranges and structural characteristics. These parameter changes in detergent composition result in improved fiber strength retention and reduced tensile strength loss during washing, directly addressing the contradiction between cleaning effectiveness and strength preservation
Solution Approach 2:
The invention uses a composite detergent system combining two distinct chemical components: alpha-substituted compounds with specific functional groups (R1, R2, X) and alkoxylated polyethyleneimines with controlled molecular weights. This composite material approach creates a synergistic effect where the combination of components provides both effective cleaning and enhanced fiber strength protection, resolving the contradiction between cleaning performance and strength retention
2Reliability
If conventional detergents are used for washing textiles, then dirt removal is achieved, but dimensional stability of textile fabric deteriorates
Solution Approach 1:
The invention modifies the chemical parameters of conventional detergents by incorporating alpha-substituted compounds and alkoxylated polyethyleneimines with specific structural parameters (molecular weight, functional groups, substitution patterns). These parameter changes result in improved dimensional stability and shape retention of textiles during and after washing, while maintaining effective dirt removal capabilities
3Reliability
If repeated washing is performed to maintain cleanliness, then hygiene is improved, but tensile strength loss accumulates over time
Solution Approach 1:
The invention applies preliminary protective action by incorporating alkoxylated polyethyleneimines that form protective films or complexes with fiber surfaces before damage occurs. This preliminary action prevents the accumulation of tensile strength loss during repeated washing cycles, allowing maintenance of cleanliness without progressive strength deterioration
Solution Approach 2:
The detergent components, particularly the alkoxylated polyethyleneimines with specific molecular weights, provide beforehand cushioning by creating a protective interface between the washing solution and fiber structure. This cushioning effect absorbs mechanical and chemical stresses during repeated washing, preventing cumulative strength loss while maintaining hygiene
