Woven Adhesive Tape with Zigzag Edges for Cable Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Adhesive tapes used for cable wrapping in the automotive sector face challenges in balancing abrasion resistance, noise damping, flexibility, and hand-tearability, often compromising on one or more properties, with existing solutions being non-machine-processable and prone to flagging.
Innovation Solution
A double-layer adhesive tape with a substrate comprising two fabric layers and an adhesive connection layer, where the fabric layers have a basis weight of 50 g/m2 to 300 g/m2, and the adhesive connection layer also has a similar basis weight, featuring a zigzag pattern on the tape edges to enhance hand-tearability and flexibility, while maintaining high abrasion resistance and noise damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the adhesive tape thickness is increased to improve abrasion resistance and noise damping, then the abrasion resistance and noise damping are improved, but the flexibility and hand-tearability deteriorate
Solution Approach 1:
The adhesive tape is divided into a double-layer substrate structure with two fabric layers of 50-300 g/m2 basis weight each, allowing the tape to maintain high abrasion resistance through layered construction while preserving flexibility and hand-tearability through appropriate layer thickness and material selection
Solution Approach 2:
The basis weight of the fabric layers is optimized within the range of 50-300 g/m2, and the adhesive connection layer is designed with similar basis weight parameters, achieving optimal balance between abrasion resistance (class E on 5mm and 10mm mandrels) and hand-tearability without requiring excessive thickness
2Object-affected harmful factors
If the adhesive tape thickness is increased to improve noise damping, then the noise damping is improved, but the flexibility deteriorates
Solution Approach 1:
The double-layer substrate structure with two fabric layers provides sufficient noise damping (class B) through the layered construction and material properties, eliminating the need for excessive thickness while maintaining high flexibility for cable wrapping applications
Solution Approach 2:
The combination of two fabric layers with adhesive connection creates a composite structure that achieves optimal noise damping (class B) and flexibility simultaneously, with each layer contributing specific properties that complement each other
3Strength
If a single thick fabric layer is used to improve abrasion resistance, then the abrasion resistance is improved, but the hand-tearability and machine-processability deteriorate
Solution Approach 1:
The substrate is segmented into two fabric layers of moderate basis weight (50-300 g/m2) connected by an adhesive layer, achieving high abrasion resistance (class E) while maintaining machine-processability through reasonable layer thickness and appropriate adhesive bonding strength
Solution Approach 2:
The basis weight parameters of the fabric layers are optimized within 50-300 g/m2 range, providing sufficient abrasion resistance for cable protection while ensuring the tape remains processable by standard manufacturing equipment
4Strength
If the adhesive connection strength is increased to improve substrate integrity, then the abrasion resistance is improved, but the hand-tearability deteriorates
Solution Approach 1:
The adhesive connection layer is designed with basis weight similar to the fabric layers (50-300 g/m2), creating optimal bonding strength that maintains substrate integrity for high abrasion resistance (class E) while preserving sufficient hand-tearability through controlled adhesive properties

AI summary
A highly abrasion-resistant technical adhesive tape rolled into an adhesive tape roll includes a strip-shaped double-layer substrate with a pressure-sensitive adhesive coating on one side. The substrate includes a first fabric layer, and a second fabric layer firmly connected to each other over the entire surface by an adhesive connection layer. An adhesive tape of this type acts in a noise-damping manner and is easily processable both manually and by machine because the fabric of the first textile layer and the fabric of the second textile layer each have a basis weight of 50 g/m2 to 300 g/m2. The adhesive connection layer has a basis weight of 50 g/m2 to 300 g/m2. The adhesive tape has a thickness (D) of at least 0.5 mm. At least one tape edge has a pattern deviating from a straight line formed by a separating process.
