PROBLEM TO BE SOLVED: To provide a hot wind spray nozzle capable of treating a fabric more efficiently using a hot wind and a hot wind spray apparatus of a tenter using the same.SOLUTION: The hot wind spray nozzle of a tenter having a shape of a polygonal duct, includes: a nozzle plate 110 horizontally disposed at a side which faces a fabric, and having a plurality of nozzle holes 150; a cover plate 120 spaced apart from the nozzle plate in the direction opposite the fabric; and both side plates 130 and 140, each of which connects both width directional edges of the nozzle plate and the cover plate. One end of the duct, formed in the shape of a polygon by both side plates 130 and 140, has a hot wind entrance 160 and the other end of the duct is a closed end. Each of the nozzle holes has a hot wind flow control piece 180 that is bent at an upstream edge S1 of the nozzle hole, which is located on an upstream side of a hot wind flow, in a direction opposite to a direction in which the hot wind is sprayed, to control the hot wind flow so that the hot wind is sprayed from each of the nozzle holes perpendicularly to the upper and lower surfaces of the fabric. |
