Fabric Shrinkage Standards Comparison

As a textile manufacturer or laboratory personnel serving international customers, it’s crucial to predict the shrinkage rate of fabrics after routine washing by the end consumers to prevent excessive fabric shrinkage that could impact the user experience and brand reputation. This article will guide you through the Fabric Shrinkage Standards Comparison among four primary international fabric shrinkage test methods.

Fabric Shrinkage Test Standards:

American Standard: AATCC 135 Dimensional Changes of Fabrics after Home Laundering
European Standard (International Standard): ISO 6330 Textiles – Domestic washing and drying procedures for textile testing
Japanese Standard: JIS L 1930 Testing methods for dimensional change of fabrics induced by laundering
Chinese Standard: GB/T 8629 Textiles – Domestic washing and drying procedures for textile testing

Fabric Shrinkage Standards Comparison on Content:

The fabric shrinkage test procedures in the European standard (International standard) ISO 6330, Japanese standard JIS L 1930, and Chinese standard GB/T 8629 are the same. The machines used in the European and Chinese standards are the same type, whereas a different machine is used in the Japanese standard. The American standard AATCC 135 washing procedure is similar to the European standard. AATCC 135 uses a different testing machine. Additionally, JIS L 1096 is another standard fabric shrinkage test method in Japan, covering a broader range of tests than JIS L 1930, which is solely used to test fabric shrinkage.

Drying Methods:

The drying methods significantly influence the fabric shrinkage testing data. The four standards include six drying methods:

Hang Drying
Hang Drip Drying
Spread Out Drying
Spread Out Drip Drying
Press Drying
Tumble Drying

Due to different lifestyle habits in various countries, the designated drying methods in the fabric shrinkage test procedures also vary. For example, hang drying is common in China, so it’s primarily used in the Chinese standards. Americans typically prefer tumble drying, so this method is included in their testing requirements but tends to result in more significant shrinkage.

Washing Temperature:

The American, Japanese, and European standards test according to the temperature indicated on care labels. The Chinese standard follows the washing temperatures specified in clothing standards.

Fabric Shrinkage Tester Machines:

American standard shrinkage tester — AATCC 135

Automatic Shrinkage Testing Machine — ISO 6330 GB/T 8629

DaRong has been manufacturing the 089 fabric shrinkage test machines suitable for European and Chinese standards for 36 years. In China, shrinkage test machines are commonly referred to as 089, which was named after the development of China’s first fabric shrinkage test machine by DaRong in 1989.

With nearly 100,000 units produced over 35 years, DaRong’s recently developed 089E is particularly commendable. It not only retains all traditional functions but also features the latest advancements: the entire machine is made of stainless steel, uses an imported AC variable frequency servo motor for step-less speed adjustment of washing and spin speeds to meet different standard requirements, and features a global brand touchscreen for intuitive operation. The silver-plated contact segment-type water level gauge accurately detects set water levels. In case of a power outage during testing, it can store the breakpoint, and testing can continue upon restart.
