Polyester Ticking Fabric Balancing Flexibility and Down Proofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Woven fabrics used for ticking in textile products, such as down jackets and sleeping bags, have low air permeability but are inferior in flexibility, which can lead to issues like inner material protrusion and impaired heat storage performance.
Innovation Solution
A woven fabric composed of multifilaments with a monofilament fineness of not more than 0.5 dtex, a large number of filaments, and a total fineness of not more than 50 dtex, preferably made of polyester, with a cover factor of at least 1,200, and subjected to water absorption and/or calender finishes to enhance flexibility and air permeability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a woven fabric with low air permeability is used for ticking, then the inner material is prevented from protruding, but the flexibility is inferior
Solution Approach 1:
The patent changes the physical parameters of the multifilament by controlling monofilament fineness (not more than 0.5 dtex), number of filaments (100 or more), and total fineness (not more than 50 dtex). This creates a fabric structure that achieves both low air permeability and high flexibility through optimized fiber dimensions and arrangement.
Solution Approach 2:
The patent uses composite multifilament structures combining multiple thin filaments (100 or more) with total fineness not more than 50 dtex. This composite approach allows the fabric to exhibit both the tightness needed to prevent protrusion and the flexibility required for comfort.
2Ease of operation
If the number of filaments is increased to improve flexibility, then the fabric becomes more flexible, but the manufacturing complexity increases
Solution Approach 1:
The patent specifies precise parameter ranges (monofilament fineness not more than 0.5 dtex, number of filaments 100 or more, total fineness not more than 50 dtex) that balance flexibility with manufacturability. These standardized parameters enable production using conventional textile equipment while achieving the desired flexibility.

AI summary
Ticking having excellent flexibility is described. A woven fabric is obtained by using a multifilament having a monofilament fineness of not more than 0.5 dtex, the number of filaments of 100 or more and a total fineness of not more than 50 dtex and used as ticking. The woven fabric can be made of a polyester.
