DC-2086 ABSTRACT OF THE DISCLOSURE An improvement in an air-jet texturing chest is disclosed. The chest is adapted to house an air jet used in the air-jet texturing of yarn and to contain water which is added to the yarn prior to its entry to the air jet and which is blown off the yarn by the air jet. The chest has: a base adapted to contain a pool of water; an air jet posi- tioned part way up the chest; an air inlet connected to the air jet; a water inlet over the pool of water; an air vent near the top of the chest; a water drain in the base of the chest; a yarn inlet to the chest; a yarn exit from the chest; and guide means adapted to lead the yarn from the yarn inlet under the surface of the pool of water, up the chest to the air jet, through the air jet and to the yarn exit. The improvement comprises a mini-pan which is adapted to contain the pool of water and which is positioned in the base of the chest away from the sides thereof. The mini-pan is useful in preventing contamination of the air jet with oil deposits which may form in the pool of water and be picked up by the yarn. The oil deposits may be formed from spin finish which together with some of the water is removed from the yarn by the air jet and which in the absence of the mini-pan (i.e. with the pool of water occupying the whole base of the chest) flows down the chest into the pool of water.
