Two-Ply Moisturizing Tissue Composition With Low Stickiness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing moisturizing tissue papers face challenges in providing softness, smoothness, and moistness while minimizing stickiness and tearability, especially for heavy users with pollen allergy or allergic rhinitis, as they tend to have low paper strength and high stickiness due to moisture-absorbing properties.
Innovation Solution
A two-ply tissue paper with a chemical agent content of 3.0 to 5.0 g/m², comprising 70-90% polyol, 1-15% moisture, and 0.01-22% functional medical agents, with a static friction coefficient of 0.55-0.60, which enhances crepe structure, fiber density, and tensile strength, reducing stickiness and improving moistness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If moisturizing agent is applied onto tissue base paper, then softness and smoothness are improved, but stickiness increases and paper strength decreases
Solution Approach 1:
The patent applies a specific amount range of moisturizing agent (3.0 to 5.0 g/m²) to optimize the balance between softness and stickiness. By precisely controlling the chemical agent content parameter, the invention achieves sufficient moisturizing effect while minimizing the harmful stickiness sensation on skin.
Solution Approach 2:
The invention uses a composite structure consisting of tissue base paper combined with a controlled amount of moisturizing agent layer. This composite material approach allows the tissue to benefit from both the structural strength of the base paper and the softening effect of the moisturizing agent, while the controlled composition prevents excessive stickiness.
2Strength
If moisturizing agent is applied onto tissue base paper, then softness and smoothness are improved, but tearability worsens
Solution Approach 1:
The patent specifies a precise range for moisturizing agent content (3.0 to 5.0 g/m²) and moisture ratio (10.0 to 13.0%) to maintain an optimal balance. By controlling these parameters, the invention achieves sufficient softness for comfort while preventing the tissue from becoming too weak and tearable.
Solution Approach 2:
The moisturizing agent is applied in a controlled manner to create local quality distribution on the tissue surface. This ensures that the softening effect is concentrated where needed for comfort, while the bulk paper structure maintains its strength and tear resistance.
3Quantity of substance
If chemical agent content is increased, then moistness is improved, but stickiness increases
Solution Approach 1:
The patent defines a specific range for chemical agent content (3.0 to 5.0 g/m²) and moisture ratio (10.0 to 13.0%) to optimize the balance between moistness and stickiness. By precisely controlling these parameters, the invention achieves sufficient moisture retention for comfort while minimizing the harmful sensation of stickiness on the skin.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tissue paper achieves high tensile strength, reduced stickiness, and maintains softness and smoothness comparable to or exceeding that of existing moisturizing tissues, while ensuring sufficient moisture retention and minimal irritation.
Implementation Method 1
When the chemicals having a specific amount of moisture are applied on the sheet constituting the two-ply tissue paper so as to permeate thereinto, the crepe structure of the sheet is expanded, so that the tissue paper having a smooth surface is formed.
Implementation Method 2
since the sheet thickness decreases and the fiber density increases with the expansion, the strength between the fibers increases, so that the tissue paper having a high tensile strength, and particularly, a high wet tensile strength in the CD direction may be obtained.
