ISO 3175 Textiles - Professional Care, Dry Cleaning and Wet Cleaning of Fabrics and Garments

The ISO 3175 standard, published by the International Standards Organization (ISO), consists of the following sub-standards under the main heading of "Textiles - Professional care, dry cleaning and wet cleaning of fabrics and clothing":

• ISO 3175-1 Part 1: Evaluation of performance after cleaning and finishing
• ISO 3175-2 Part 2: Procedure for testing performance during cleaning and finishing using tetrachloroethene
• ISO 3175-3 Part 3: Procedure for testing performance during cleaning and finishing using hydrocarbon solvents
• ISO 3175-4 Part 4: Procedure for testing performance during cleaning and finishing using simulated wet cleaning
• ISO 3175-5 Part 5: Procedure for testing performance during cleaning and finishing using dibutoxymethane
• ISO 3175-6 Part 6: Procedure for testing performance during cleaning and finishing using decamethylpentacyclosiloxane

The ISO 3175-1 standard describes a method for evaluating textile products tested according to ISO 3175‑2 and ISO 3175‑4. In this method, changing fabric and clothing properties in dry cleaning or wet cleaning and finishing processes are determined and methods for evaluating the change are explained using existing international standards. Other products, which are also important but for which there are no international standards providing assessment methods, are included in the appendix to the standard, along with recommendations on how to proceed with their assessment.

For the purposes of this standard,

• Composite test specimen refers to the test specimen made up of all the component parts used in the finished product and assembled in a representative assembly.
• Dry cleaning refers to the degree to which a product consisting of all its component parts can be cleaned by immersion by shaking in an organic solvent commonly used for this purpose. This process consists of cleaning, centrifugal extraction, drying and finishing to restore shape and appearance.
• Wet cleanability refers to the degree to which a product consisting of all its component parts can be cleaned by immersing it in an aqueous solution and agitating it in specialized equipment commonly used for this purpose. This process consists of cleaning, centrifugal extraction, drying and finishing to restore shape and appearance.

The ISO 3175-2 standard describes dry cleaning procedures for tetrachloroethene (perchlorethylene) using commercial dry cleaning machines for fabrics and clothing. This standard contains procedures for normal and sensitive materials. Local staining and stain removal are beyond the scope of this standard.

For the purposes of this standard,

• Material refers to a garment, composite test specimen, or fabric.
• Composite test specimen refers to the test specimen made up of all the component parts used in the finished product and assembled in a representative assembly.
• Normal material refers to material consisting of all component parts that can withstand the normal dry cleaning process specified in this standard without modification.
• Sensitive material refers to material consisting of all component parts that require restrictions on mechanical action or drying temperatures or water additions. For example, the fiber type is acrylic, modacrylic, silk, angora and the fabric type is crepe.

The ISO 3175-3 standard describes dry cleaning procedures for hydrocarbon solvents using commercial dry cleaning machines for fabrics and clothing. This standard contains procedures for normal and sensitive materials. Localized staining and stain removal are outside the scope of this standard.

The ISO 3175-4 standard describes simulated professional wet cleaning procedures for fabrics and garments using a reference machine. This standard is designed for non-washable fabrics and garments that require professional finishing. It includes a normal treatment for normal materials, a light treatment for sensitive materials, and a very light treatment for very delicate materials. Local staining and stain removal is beyond the scope of this document.

For the purposes of this standard,

• Very delicate material refers to material that can withstand very light simulated professional wet cleaning. Very sensitive material relates to the maintenance symbol in Table 3758 of the ISO 6 standard.
• The normal simulated professional wet cleaning process refers to a cleaning procedure in 40 degrees water followed by tumble drying at 3 degrees to less than 60 percent residual moisture. The requirements for this cleaning procedure are in Table 1.
• The lightly simulated professional wet cleaning process refers to a 30 degree water cleaning procedure followed by tumble drying at 15 degrees to approximately 60 percent residual moisture. The requirements for this cleaning procedure are in Table 1.
• Professional wet cleaning process with very light simulation means cleaning procedure in 30 degrees water, followed by tumble drying for 40 minutes at 2 degrees maximum, followed by air drying. The requirements for this cleaning procedure are in Table 1.

The ISO 3175-5 standard describes dry cleaning procedures for dibutoxymethane using commercial dry cleaning machines for fabrics and clothing. This standard contains procedures for normal and sensitive materials.

The ISO 3175-6 standard describes dry cleaning procedures for decamethylpentacyclosiloxane using commercial dry cleaning machines for fabrics and clothing. This standard contains procedures for normal and sensitive materials.

Dry cleaning is the process of cleaning textiles in an organic solvent that dissolves oils and fats and largely disperses particulate dirt without the swelling and wrinkling associated with washing or wet cleaning. A small amount of water can be added to the solvent with the help of a detergent to achieve better dirt and stain removal. Some moisture sensitive products are dry cleaned preferably without adding water to the solvent. A detergent is often used to aid in soil removal and reduce the risk of greying, but it should be borne in mind that detergents contain varying amounts of water in their formulation.

Dry cleaning is normally followed by an appropriate restorative finishing procedure. In most cases this involves some form of steam treatment or hot pressing.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for professional care, dry cleaning and wet cleaning of fabrics and clothing, within the scope of ISO 3175 standard, with its trained and expert staff and advanced technological equipment. .
