Polyester acetate tear-away printed label and methods of manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional printed labels face issues with production efficiency, cost, and environmental concerns due to strict technical requirements, including potential fading of logo colors, fraying of label edges, and excessive formaldehyde concentrations, which can be harmful.
Innovation Solution
A polyester acetate tear-away printed label is manufactured using polyester acetate filament yarns, involving processes like weaving, sizing, desizing, alkali peeling, shaping, coating, and slitting, which enhances the label's strength and environmental friendliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional printed labels are manufactured using conventional methods, then production efficiency is high and cost is low, but logo colors may fade, label edges may become frayed and damaged more easily, and excessive formaldehyde concentrations may remain
Solution Approach 1:
The patent changes the material parameter from traditional polyester to polyester acetate filament yarn, which fundamentally alters the chemical and physical properties of the label. This parameter change enables the label to resist fading, fraying, and formaldehyde accumulation while maintaining production efficiency, as the new material inherently possesses these improved properties without requiring complex process modifications
Solution Approach 2:
The patent uses polyester acetate composite filament yarn that combines the advantages of polyester (strength, durability) and acetate (environmental friendliness, resistance to formaldehyde). This composite material approach allows the label to simultaneously achieve high production efficiency and superior quality characteristics including color fastness, edge stability, and reduced harmful substances
2Ease of manufacture
If traditional materials are used for printed labels, then manufacturing process is simple, but environmental friendliness is poor and strength is insufficient
Solution Approach 1:
The patent modifies the material composition parameter by introducing acetate components into the polyester structure. This parameter change maintains the simplicity of the manufacturing process while dramatically improving environmental friendliness and label strength, as polyester acetate is biodegradable and free from harmful formaldehyde residues
Solution Approach 2:
The patent employs polyester acetate filament yarn that can be produced using conventional textile manufacturing processes, keeping production costs low and manufacturing simple. The material's inherent biodegradability and lack of harmful substances provide environmental benefits without requiring complex disposal systems, effectively treating the label as an environmentally safe disposable product

AI summary
A polyester acetate tear-away printed label and associated methods of manufacture are disclosed. In at least one embodiment, one such method of manufacture involves weaving a base cloth using polyester acetate filament yarns, sizing and oiling the base cloth, desizing and refining the base cloth using a jet grouting overflow machine having a low desizing bath ratio, performing an alkali peel on the base cloth, shaping and drying the base cloth, further shaping the base cloth, coating the base cloth, and slitting the base cloth into desired dimensions.
