How to protect and deal with the shrinkage of acetate eyewear?

Acetate eyewear refers to eyeglass frames made from a type of plastic material known as acetate.
Acetate is a strong and light substance made from renewable sources. It is commonly used for glasses frames because it can be easily shaped and comes in a wide range of colors and designs.
Eyewear manufacturers often source their acetate material from different suppliers based on their specific needs. Some well-known acetate manufacturers in the eyewear industry include Mazzucchelli 1849, Jinyu, Jimei, KingYe.....



What is the advantages of "Acetate Glasses Frames" include?

Lightweight and Comfortable: Acetate is a lightweight and durable material, making glasses and sunglasses more comfortable to wear without causing pressure.
Design Flexibility: Acetate is easy to work with, allowing eyewear designers to create unique and personalized styles, providing more options.
The great thing about acetate is that it's super easy to dye, so you've got tons of color and texture options to choose from. That way, you can pick something that really matches your personal taste and style.
Hypoallergenic: Compared to some metal eyewear, acetate is generally more suitable for individuals with metal allergies, as it is a non-metallic material.
Environmentally Friendly: Acetate is often renewable and biodegradable, making it more environmentally friendly compared to some other eyewear materials such as plastic or metal.

However ,A problem with acetate eyewear is that it can shrink over time, causing the frames to become small, tight, and unbalanced.


To solve the problem of shrinkage in sheet glasses, we need to first understand why it is happening. Here are a few possible reasons.
Humidity Changes: Sheet glasses, might be sensitive to humidity. In places with changing humidity, these materials can soak up or let out moisture, which affects the size of the glasses.
Temperature Changes: Temperature variations can also result in expansion or contraction of glass materials. High temperatures may cause the glasses to expand, while low temperatures may lead to shrinkage.
Manufacturing Process Issues: Issues in manufacturing, such as temperature or pressure problems, or variations in material quality, can cause glasses to shrink when used.
Material Selection: The chosen glasses material itself might be more prone to shrink under specific conditions. Different materials may react differently to humidity and temperature.
Improper Maintenance: Incorrect care and storage methods may also result in the deformation of glasses. Exposure to humid or high-temperature environments or storing them in unstable conditions could adversely affect the glasses.

When making "acetate eyeglasses," it's important to prevent shrinkage because acetate material tends to shrink.
Our eyewear factory normally pay attention as below to help prevent shrinkage during the acetate eyewear manufacturing process.
Material Selection: Ensure the use of high-quality acetate materials.
Environmental Control: Use air conditioning or humidifiers to control climate conditions within the factory.
Production Processes: Baking the material with enough time .Control the temperature when bend the frame.


However, if it shrinks, our factory has ways to address this issue. Firstly, we need to assess the severity of the problem, such as through thorough hand scraping or sanding.
For minor imperfections, a light touch-up with 1200-grit sandpaper followed by direct polishing may suffice. The approach taken depends on the specific situation. If you are interested in discussing further details, please feel free to contact us

When you receive acetate eyewear, here are some tips to prevent it from shrinking and what to do if it does happen
Prevention of Shrinkage:
Avoid High Temperature and Humidity: Acetate is sensitive to high temperatures and humidity, so it should be avoided to leave glasses in hot or humid places such as direct sunlight or damp areas for extended periods of time.
Choose Appropriate Storage Conditions: Store acetate glasses in a dry, well-ventilated place away from heat sources and humidity. Use a glasses case to protect them from external influences.
Avoid Chemicals: Prevent aceatte glasses from coming into contact with chemicals, especially solvents found in cleaning agents or cosmetics. These substances may have adverse effects on cellulose acetate.

Dealing with Shrinkage:
Stop Using the Glasses: If you notice that the glasses, eyewear, sunglasses have already shrunk, stop using them to prevent further damage.
Restore Shape: Attempt to gently manually restore the shape of the glasses. You can lightly bend the glasses to return them to their original shape. However, be cautious not to apply excessive force to avoid causing additional damage
Get professional help: If the glasses are still a problem, go to a repair shop or optician. They will check and fix the issue.

If you are concerned about acetate eyewear frames becoming deformed, you may consider exploring eyeglass frames made from alternative materials .
Such as Metal eyewear, Titanium eyewear, Stainless steel eyewear, Aluminum eyewear, TR90 eyewear, Injected plasic eyewear.
