Two-Ply Moisturizing Tissue Paper Balancing Softness and Toughness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Moisturizing tissue papers face challenges in achieving excellent sensory performance, particularly in balancing 'moist feeling' and 'smoothness' while maintaining 'toughness' due to increased moisture content, which often compromises 'sticky feeling' and 'toughness' evaluations.
Innovation Solution
A two-ply tissue paper with a basis weight of 15.9 to 17.9 g/m² and thickness of 140 to 175 µm, containing polyol, hyaluronic acid, fatty acid ester-based compounds, and fatty acid amide-based compounds, which enhance moisture retention, surface smoothness, and fiber coating, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If moisture content is increased by a moisturizing agent, then 'softness' and 'moist feeling' are enhanced, but 'toughness (strength/secure feeling)' and 'smoothness' are lowered
Solution Approach 1:
The patent optimizes the moisture content parameter to a specific range of 15-25% through controlled addition of moisturizing agents. This parameter change resolves the contradiction by finding the optimal point where softness and moist feeling are sufficiently enhanced while toughness and smoothness remain acceptable, avoiding the negative effects of excessive moisture content.
2Quantity of substance
If moisture content is increased by a moisturizing agent, then 'softness' and 'moist feeling' are enhanced, but 'smoothness' is lowered due to sticky feeling from chemicals
Solution Approach 1:
The patent controls the moisture content within the optimal range of 15-25% and selects moisturizing agents with appropriate molecular structures. This parameter optimization prevents excessive stickiness while maintaining softness and moist feeling, thereby preserving surface smoothness.
Solution Approach 2:
The patent uses composite moisturizing systems combining multiple agents including polyols (glycerin, propylene glycol), amino acids, and hyaluronic acid. This composite approach balances the hygroscopic properties for moisture retention with surface properties that minimize sticky feeling, thus maintaining smoothness while achieving softness enhancement.
