The invention relates to a cotton fabric super-hydrophobic coating fabric splicing patient garment with a temperature detecting device. The cotton fabric super-hydrophobic coating fabric splicing patient garment with the temperature detecting device comprises a garment front part (1), a garment rear part (2) and two sleeves (3), the garment front part (1) and the rear part are connected through zippers (4), the sleeves (3) are connected with the garment front part (1) and the rear part through annular zippers (5), interlayers (6) are arranged at positions of armpits of the garment front part (1), an infrared temperature detector (7), a central processing unit (CPU) (8) and a global system for mobile communications (GSM) module (9) are disposed in the interlayers (6), the garment front part, the garment rear part and the sleeves are made of fabrics, the fabrics comprise cotton fabrics, nanometer silicon particle layers coat double surfaces of the cotton fabrics, and hydrophobic fluorine quaternary amine silane coupling agent coatings coat surfaces of the nanometer silicon particle layers. Body temperature can be real-timely monitored by the cotton fabric super-hydrophobic coating fabric splicing patient garment with the temperature detecting device. The cotton fabric super-hydrophobic coating fabric splicing patient garment with the temperature detecting device can make a wearer feel comfortable.
