Layered Textile Structure for Lightweight Seam Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile products face challenges in achieving effective sealing without using a knit on the side for sealing treatment, which results in insufficient sealing, weight issues, and compromised appearance and touch feeling.
Innovation Solution
A layered product comprising a flexible film and a woven fabric laminated on the side for sealing, with a total cover factor ranging from 700 to 1400, and additional features like a hydrophilic resin layer and textured yarns to enhance impregnation and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a knit is laminated on the side for sealing treatment, then sealing effect is improved, but weight increases and abrasion resistance deteriorates
Solution Approach 1:
The invention changes the parameter of fabric type from knit to woven fabric, and optimizes the cover factor to a specific range (700-1400) to achieve both good sealing effect and reduced weight. This parameter optimization allows the woven fabric to provide adequate impregnation for sealing while being lighter and more durable than knit alternatives.
Solution Approach 2:
The invention applies local quality by using a woven fabric with specifically optimized cover factor characteristics on the sealing side, rather than using a knit fabric throughout. The cover factor is tailored to provide the right balance of impregnation capability and weight reduction for the sealing application.
2Reliability
If a knit is laminated on the side for sealing treatment, then sealing effect is improved, but appearance and touch feeling deteriorate
Solution Approach 1:
The invention changes the fabric structure parameter from knit to woven, which fundamentally alters the surface characteristics. Woven fabrics provide a smoother, more uniform surface that maintains better appearance and touch feeling while still achieving effective sealing through optimized cover factor.
3Reliability
If the cover factor is increased to improve sealing, then impregnation is improved, but weight increases
Solution Approach 1:
The invention optimizes the cover factor to a specific range (700-1400) rather than simply increasing it indefinitely. This optimized range provides sufficient impregnation for effective sealing while avoiding the weight penalty that would result from higher cover factors. The precise parameter optimization balances sealing performance with weight reduction.

AI summary
The present invention provides a layered product, which, when processed into a textile product by sewing, fusing, or the like, overcomes such a practical restriction that a knit must be used on the side to be subjected to a sealing treatment, makes the sealing treatment easier, has intact appearance and touch feeling, and is lightweight. The layered product comprises a flexible film and a woven fabric layered thereon at the side to be subjected to the sealing treatment in processing the layered product into the textile product. The layered product has a total cover factor (CFtotal) from 700 to 1400, calculated from the cover factors of the warp and the weft constituting the woven fabric.CFtotal=CFm+CFt CFm: cover factor of warpsCFt: cover factor of wefts
