Since 1921, the AATCC has been serving the textile industry. During [[World War I]], when the Atlantic blockade prevented European dyes from entering America and the newly formed American dye manufacturers struggled to provide consistent products, the need for American textile testing methods became apparent.<ref>{{Cite web |title=History |url=https://www.aatcc.org/history/ |access-date=2022-11-21 |website=AATCC |language=en-US}}</ref> The AATCC has developed over two hundred textile standards, test methods, evaluation procedures, and monographs. These specifications are published annually in the AATCC Technical Manual.<ref>{{Cite web |title=AATCC Testing |url=https://www.aatcc.org/testing/ |access-date=2022-11-21 |website=AATCC |language=en-US}}</ref>
The [[American National Standards Institute]] approves the textile performance standards set by [[ASTM International]].{{sfn|Tortora|Collier|1997|page=[https://archive.org/details/understandingtex00tort 20, 21]}} Other testing agencies or bodies that are

Textile testing is conducted at various stages, including raw materials, fibers, yarn, fabric, and finished product.

Cotton's simple Micronaire value is determined by both the fineness of the fibres as well as their maturity.<ref>{{Cite web |title=Micronaire - an overview {{!}} ScienceDirect Topics |url=https://www.sciencedirect.com/topics/engineering/micronaire |access-date=2021-08-29 |website=www.sciencedirect.com}}</ref> Micronaire values or reading represents the fineness of the cotton fiber. For example, a preferred micronaire range is 3.7 to 4.2. [[Gossypium hirsutum|Upland cotton]] is coarser than [[Gossypium barbadense]] (Pima cotton).<ref>{{Cite book |last1=Fang |first1=David D. |url=https://books.google.com/books?id=amDMDwAAQBAJ&dq=micronaire+value+of+cotton&pg=PA708 |title=Cotton |last2=Percy |first2=Richard G. |date=2020-01-22 |publisher=John Wiley & Sons |isbn=978-0-89118-625-0 |pages=708 |language=en}}</ref>

Fabric testing includes measurements such as [[Units of textile measurement#Grams per square metre (GSM)|fabric weight]], fabric width, [[Dimensional stability (fabric)|shrinkage]] testing, [[colour fastness|colour fastness to washing]], [[Lightfastness|fastness to light,]] [[Pill (textile)|pilling]], tearing and bursting strength, etc.
