Finishing agent composition for textile products
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional textile softening methods using anionic and nonionic surfactants often result in insufficient rinsing, leading to hard textures and reduced water absorbency in textile products, while cationic surfactants may decrease water absorbency and cause softness issues.
Innovation Solution
A fiber modifier and finishing agent composition utilizing an internal olefin sulfonate with 17 to 24 carbon chain length, which is used in a treatment liquid to impart softness to textiles without reducing their original water absorbency, by contacting the textiles with a solution containing 0.002% to 6% of the internal olefin sulfonate by mass.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If anionic surfactants are used for washing and cationic surfactants are used for softening, then softness is improved, but water absorbency is reduced and hard texture occurs due to insufficient rinsing
Solution Approach 1:
The invention changes the chemical parameter of the surfactant from conventional anionic/cationic types to internal olefin sulfonate with specific carbon chain length (17-24 carbons). This parameter change enables the surfactant to provide softness while maintaining water absorbency, resolving the contradiction between softness improvement and water absorbency preservation
Solution Approach 2:
The invention uses a composite approach by combining internal olefin sulfonate with specific physical properties (carbon chain length 17-24) to create a finishing agent that integrates both softening function and water absorbency maintenance, eliminating the need for separate washing and softening steps
2Productivity
If conventional surfactants are used with short rinse time or low water usage, then productivity is improved, but hard texture and reduced water absorbency occur
Solution Approach 1:
The invention changes the chemical structure parameter of the surfactant to internal olefin sulfonate with 17-24 carbon atoms, which has superior rinsing properties. This allows effective softening even with short rinse times or low water usage, maintaining texture quality while improving productivity
3Ease of operation
If cationic surfactants are used for softening, then softness is improved, but water absorbency decreases
Solution Approach 1:
The invention changes the surfactant type from cationic to internal olefin sulfonate with specific carbon chain length (17-24 carbons). This parameter change fundamentally alters the interaction mechanism with textile fibers, providing softness through a different chemical mechanism that does not compromise water absorbency
