The chamber has an exhaust system, and the air distributors communicate with the cold-agent-inducing unit. Air distributors are mounted with the possibility of their simultaneous rotation around their axis in opposite directions, 1 hp f-crystals, 4 Il.

Description

The invention relates to equipment for finishing textiles, namely, artificial knitted fur.

Nowadays, the artificial knitted fur has a pile cover, which is prone to stalling under the operating conditions, the formation of knots and moire stains, which leads to a loss of appearance and shortened service life of articles made of artificial fur.

The main reason for these shortcomings of artificial knitted fur is the ineffective fixation of the fibers of the pile cover, which can be achieved by rapidly cooling the fur sheet and then heating it in a tumble dryer.

Used in industry for heat treatment of fur drying machines are equipped with cooling chambers, the principle of work of which is based on blowing the fur sheet with air streams supplied by the ventilation unit from the workshop through slits of the refrigerating chamber air distributors

Known devices do not allow the regulation of air flow; the cooling air is taken from the heated section of the workshop and the waste is again thrown into the workshop, raising the temperature of the air in the cooling chamber zone. In addition, loose fibers of the pile fur cover are blown out by air flows into the working area of the drying-plunger, creating unsanitary work conditions and taken from the workshop With air flow, the fibers are deposited on the fan grid, cutting off the air supply to the cooled fur surface. HI devices provide the necessary degree of cooling of the fur due to the absence of an abrupt transition from a hot to a cold state and, consequently, a sufficient fixation of the XJ

tuft cover curl, which affects the quality of the final finishing of the fur - shearing and ironing.

Closest to the present invention, there is a device for treating textile materials, which allows for a sharp cooling of the web in the cooling chamber after it is heated in a drying-spreading machine. The air temperature for the cooling chamber is reduced using liquid nitrogen. To distribute the cooling air flow along the entire length, rectangular cross-section diffusers are installed with nozzles in the form of holes or slots, the magnitude of which is constant and specified for a particular type of material being processed.

A device of this design cannot be used to treat artificial fur, since it creates a constantly directed perpendicular to the nap surface of turbulent air flows, which, whirling, cause the pile to collapse, the orientation of the fibers in different directions. The resulting pile covering defects in the form of strips, moire stains, different shades are not eliminated in the subsequent operations of the final finishing of the fur.

The aim of the invention is to intensify the cooling process and improve the quality of the textile material being processed.

FIG. 1 shows the device, a general view; in fig. 2 - air distributor, general side view; FIG. 3 is a view A of FIG. 2; in fig. 4 shows a section BB in FIG. 2

The device comprises a chamber 1 connected to the exhaust system 2.

A chain conveyor 3 is placed in the chamber to transport material 4 and air distributors 5 are installed on its two sides, communicating with the unit 6 forcing the cold agent. The unit b has a fan (not shown) and a heat exchanger 7. Each air distributor 5 has the shape of a truncated cone with a decrease in taper in the direction of movement of the cold agent and communicating with the larger side with the cylindrical nozzle 8.

Slots 9 with flanging 10 are provided along each diffuser for adjusting the width of the slot.

Air distributors have the means of their simultaneous rotation around their axis in opposite directions. For this, it has axles 11 fixed on the smaller side of the cone, on which sprockets 12 are attached, connected by a chain 13, a drive sprocket 14, on the axis of which a flywheel 15 is mounted. The exhaust system has a downspout 16.

The device works as follows.

Depending on the processing parameters of the textile material and depending on the climatic conditions, set the required cooling temperature.

air using a heat exchanger 7; The amount of air supplied to the cooling chamber is controlled by the fan of the injection unit 6. The direction of the air stream to the pile surface of the material being processed is set by turning the air distributors 5 around its axis at the inlet nozzles 8.

The movement of the air distributors 5 is transmitted from the handle 12 of the flywheel 15 through the drive sprocket 14, the chain 13 and the sprockets 12, which sit on the axles 11 of the air distributors. In this way, the air distributors of the upper and lower rows are turned in opposite directions.

sides at an angle of 5-85 ° from the perpendicular to the restored to the surface of the textile material. The width of the slots of the air distributors is established by diluting the silt and pinching,

With this device, the cooling process of the textile material is significantly intensified. The fur cloth having a temperature / ru 130-140 ° C is cooled to 10-25 ° C along the ground and 10-12 ° C

on pile. The released heat from the exhaust air is taken up by the exhaust system from the working area and after the collection of loose fibers by the collection of the loose fibers and the fluff is fed to the heat exchanger for cooling.

When the textile material is heated in a dry-tentering machine, the fibers relax due to the weakening of the intermolecular bonds and the release of internal stresses. The new stabilized state of the fibers is securely fixed when the material is cooled rapidly in the cooling chamber.

The invention provides an increase

the quality of the processed artificial fur due to the increased resistance of the fibers of the pile cover to crushing, reduction of shrinkage of the fabric, improvement of working conditions,
