Textile-Strengthening Detergent for Tensile and Shape Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detergents cause harsh treatment of textiles during washing, leading to a loss of tensile strength and shape retention over time.
Innovation Solution
A detergent comprising alpha-substituted compounds and alkoxylated polyethyleneimines, specifically formulated to improve fiber and textile properties, with alpha-substituted compounds in the range of 0.000001 - 2.0 wt% and alkoxylated polyethyleneimines in the range of 0.2 - 5.0 wt%, enhancing tensile strength and shape retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional detergents are used for washing textiles, then cleaning effectiveness is achieved, but tensile strength and shape retention of textiles deteriorate over time
Solution Approach 1:
The patent introduces alpha-substituted compounds and alkoxylated polyethyleneimines as intermediary substances that mediate between the detergent and textile. These compounds form a protective complex on the textile surface during washing, reducing direct harsh interaction between conventional detergent components and the textile fibers, thereby preserving tensile strength while maintaining cleaning effectiveness
Solution Approach 2:
The patent changes the chemical parameters by introducing specific alpha-substituted compounds with particular molecular structures (formula I) and alkoxylated polyethyleneimines with specific degrees of substitution. These parameter changes in chemical composition create a protective film on textiles that reduces mechanical damage during washing, resolving the contradiction between cleaning power and strength retention
2Ease of manufacture
If conventional detergents are used for washing textiles, then dirt removal is achieved, but shape retention of textiles deteriorates over time
Solution Approach 1:
The alpha-substituted compounds and alkoxylated polyethyleneimines act as intermediary protective agents that form a flexible film on the textile surface. This film allows dirt to be removed effectively while maintaining the textile's original shape by preventing excessive fiber deformation and relaxation during the washing cycle
Solution Approach 2:
The protective compounds are applied preliminarily during the washing process to form a protective layer on the textile before mechanical stress occurs. This preliminary action of coating the fibers creates a buffer that prevents shape distortion and helps the textile return to its original form after washing
