BS EN ISO 2313-1:2021

What is ISO 2313-1- Angular recovery of a horizontally folded cloth specimen from creases about?  

ISO 2313-1 is a series on textiles. A textile is a flexible material made by creating an interlocking bundle of yarns or threads, which are produced by spinning raw fibres into long and twisted lengths. ISO 2313-1 specifies a method for determining the angle of recovery of fabrics from creasing. The results obtained by this method for textile fabrics of quite various kinds cannot be compared directly. 

Who is ISO 2313-1- Angular recovery of a horizontally folded cloth specimen from creases for? 

ISO 23131 on textiles is useful for: 

• Textile manufacturer and retailer  
• Textile testing institution  
• Quality control personnel 

Why should you use ISO 2313-1- Angular recovery of a horizontally folded cloth specimen from creases?  

Textiles are constructed of many fibres, including wool and silk. That is how loose ends are straightened up. The ability of a cloth to regain its original shape after being crumpled is called "crease recovery." The crease resistance angle is calculated. Resin treatment of textiles speeds up wrinkle healing. Cloth creases that have occurred throughout the manufacturing process must be repaired. To assess the crease recovery angle of a fabric specimen, ISO 23131 places it so that the folded line is horizontal to the vertical plane for a given time. Weights are added and held on a folded specimen for a long time. The crevice recovery angle is determined by holding the specimen parallel to the vertical. 

During folding, chains grow, eliminating weak hydrogen bonds. They form new hydrogen bonds in strained places to preserve the creases. A new appearance for the fabric. This is why fabrics have crease-healing compounds. Comfortable fabrics with softening agents. These substances may soften, smooth, fluff, and silken materials. 

The crease healing procedure improves the fabric's overall quality and function. Textiles made to suit end-user demands will enhance demand, output, money, and goodwill in the market. ISO 2313-1 specifies how to determine a fabric's crease recovery angle. 

What is changed since the last update?  

BS EN ISO 2313-1:2021 supersedes ISO 2313:1972. BS EN ISO 23131:2021 includes some technical changes with respect to ISO 2313:1972. These include: 

• Changing the normative reference 
• Adding the tolerance of the load on the specimen 
• Redrafting the description about "Sampling and preparation of specimens” to improve the clarity of meaning 
• Revising the distance from the selvage while taking the specimen, i.e., from “not less than 50 mm” to “not less than 150 mm” 
• Revising the requirement of atmosphere for conditioning and testing
