HomeGrown Pure Cotton™
Cotton Proudly Grown in the USA
HomeGrown Cotton uses SigNature T molecular tags to tag and test American-grown Upland pure cotton. Upland is the most widely planted species of cotton in the United States, accounting for at least 97% of all cotton production, or roughly 7 billion pounds per year.
Upland cotton grown in the US is ginned and tagged in California, Arkansas and Texas.
SigNature T DNA is a custom molecular tag that bonds tenaciously to natural fibers. Once tagged, the molecular code remains bound to cotton and can be recovered successfully from samples at key points in the supply chain. SigNature T tags can survive harsh manufacturing processes, providing secure and cost-effective assurance of quality and authenticity.
DNA Transfer System
To achieve cotton certainty, SigNature T DNA tagging is complemented with fiberTyping®
fiberTyping is a patented DNA test that can be used to determine if a product contains the presence of Gossypium barbadense DNA (Extra Long Staple “ELS”), Gossypium hirsutum DNA (Upland), or a blend of both. fiberTyping is a powerful tool to help the cotton industry ensure that products labeled as 100% ELS, or 100% Pima, are compliant with label claims.
