Embodiment Construction

[0018] figure 1 A continuous autoclave steaming plant 1 is shown comprising an autoclave 2 equipped with a cylinder 3 which is heated and rotatable about its axis. The apparatus 1 also comprises a first conveyor belt 4 and a second conveyor belt 5 supported by suitable rollers and adapted to sandwich the fabric 6 to be treated between them and passing through the inlet sealing groove 7 The fabric 6 is brought into the autoclave 2 and then taken out of the autoclave 2 through the outlet sealing groove 7'. The inlet sealing groove 7 and the outlet sealing groove 7 ′ can, for example, be nips formed between suitable sealing rollers 8 , 9 and 10 . Inside the autoclave 2, one or more rollers 11 may be arranged, suitable for supporting conveyor belts 4 and 5 which sandwich the fabric 6 to be treated between them. The conveyor belts 4 and 5 are arranged so as to surround the cylinder 3 and adhere to most of its cylindrical sides.

Abstract

An apparatus (1) for continuous autoclave decatizing which comprises an autoclave (2) containing a cylinder (3) being heated and rotatable around its axis. Said apparatus (1) further comprises a firstconveyor belt (4) and a second conveyor belt (5) which are supported by rolls and suitable to sandwich between themselves a fabric to be treated (6) and to carry said fabric (6) into the autoclave (2) through an inlet sealing slot (7) and out of the autoclave (2) through an outlet sealing slot (7'). The conveyor belts (4, 5) are arranged so as to surround the cylinder (3) and adhere to the cylindrical lateral surface thereof. Further, said apparatus (1) is provided with an internal jacket (13) which can be heated by heating means (14) and is coaxial to the autoclave (2). Said internal jacket(13) and said heated cylinder (3) are suitable to be heated up to temperatures ranging from 160 DEG C to 200 DEG C in order to overheat in a combined way the interior of the autoclave (2) up to a temperature higher than 14O DEG C and the apparatus is provided with means (12) for injecting steam into the autoclave (2). The apparatus (1) is also provided with water injecting means (12, 18, 18', 19)suitable to inject water into the autoclave (2).

Description

technical field [0001] The present invention relates to an apparatus for continuous steaming in an autoclave, which is particularly suitable for providing optimum steaming in a short time. Background technique [0002] Autoclave steaming is known to be most effective for steaming wool, synthetic or blended fabrics. In fact, temperatures higher than 100° C. can be achieved in the autoclave in order to prevent the moisture contained in the steam from evaporating due to the effect of the high pressure in the autoclave, usually higher than 1.5 atmospheres. [0003] This characteristic is why autoclave steaming produces durable results; in fact, the luster and touch provided by steaming are neither washed nor ironed, nor suppressed by the steam used by garment manufacturers. damage. This durability of performance cannot be obtained by steaming in an atmospheric pressure environment. In fact, in the normal steaming process, in the environment of natural atmospheric pressure, th...
