The Pure Wool Logo is a textile trademark authorized by the International Wool Bureau and is a guarantee of quality and confidence in wool products. It is an internationally renowned trademark that proves that the knitted garment you are buying is made of pure new wool. "Pure" means using 100% wool; "new" means that no recycled wool is used in wool products. Let's take a closer look at the pure wool logo and the difference between pure wool and 100% wool!
First, what is the pure wool logo
In order to maintain the identity of natural high-quality fibers, the International Wool Bureau designed the "Pure Wool Mark" composed of three wool balls in 1964, where the pure wool products meet the quality requirements such as strength, color fastness, wear resistance, washability and other quality requirements formulated by the International Wool Bureau, approved by the Bureau, the "Pure Wool Mark" can be used, and the pure wool mark has become a well-known textile mark in the international market.
The International Wool Bureau began to develop business in China in 1980, and in 1989 reached a cooperation agreement with the China Import and Export Commodity Inspection Corporation on the inspection of products using pure wool marks in China's export textiles. The agreement stipulates that since July 1, 1990, all wool products exported in China with pure wool marks will be managed by the China Commodity Inspection Corporation, and local branches will be responsible for testing and visual inspection.

Second, the meaning of the pure wool logo
The pure wool logo is a promise of quality and fibre content. It is an internationally renowned trademark that proves that the knitted garment you are buying is made of pure new wool. "Pure" means using 100% wool; "new" means that no recycled wool is used in wool products. This is extremely important because the quality of the recycled wool is destroyed and the products produced from the recycled wool must not be marked with pure wool.
More than half a billion people in the world know the pure wool logo, so it is the world's most famous textile symbol, and the wool blend logo, which is also a symbol of wool content and quality, also has a high recognition rate in the world.
Textile trademarks authorized by the International Wool Bureau are a guarantee of the quality and confidence of wool products. This woolmark, which resembles a yarn, can be found everywhere in China. Since its introduction 34 years ago, it has gained considerable popularity around the world, especially in Europe and Japan. In Japanese department stores, you can find the brand's men's and women's wool sets, cardigans and wool home textile products with pure wool logos. In China, most people only think that this logo represents only ingredients, but in fact, only wool products that pass a series of product standards of the International Wool Bureau can hang a pure wool logo.
Third, the difference between pure wool and 100% wool
According to the regulations of the national textile industry, wool sweaters with a wool fiber content of 100%, whether worsted or woolen, are called "pure woolen sweaters". But in fact, in order to improve the spinning performance and increase the durability, the worsted finished product is allowed to contain no more than 5% non-wool fibers (such as nylon, polyester, etc.). The woolen finished product is allowed to contain no more than 7% non-wool fibers.
If it is used for decoration and the decorative fiber must be visible, the non-wool fiber content of the worsted finished product can be relaxed to 7%. Woolen finished products are allowed to contain no more than 7% non-wool fibers, but the total amount of both (referring to the purpose of decorating and improving spinning properties) must not exceed 7%.
If the pure wool sweater is added to the non-wool fiber allowed in the standard, whether worsted or woolen products, it can only be marked with "pure wool", not "100% wool", and only finished products with a gross content of 100% can be marked with "100% wool" on the sewn trademark or hang tag.
