This study develops an eco-friendly natural dyeing process for Eco Print and patterned textiles using local mordants—fermented pineapple, coffee, vinegar, rust water, limewater, and lemon—to enhance color fixation, shade variation, and durability. Results showed clear patterns and high satisfaction (x̅ = 4.73). The products support sustainable fashion, local identity, and community-based eco-friendly industries, highlighting regional motifs like “Kleaw Rak Krabi.”
