I'IAKOTO ARAKAWA' Oct. 4, 1960 MASAHIDE YAZANA EI'AL CONTINUOUS TREATMENT OF TEXTILE MATERIAL UNDER PRESSURE Filed May 3, 1955 United States Patent CONTINUOUS TREATMENT OF TEXTILE MATERIAL UNDER PRESSURE Filed May '3, 1955, Ser. No. 505,800 1 Claim. 01. 68-
The present invention relates to an apparatus for continuously treating textile material as in an autoclave.
This invention is characterized by the use of narrow nozzles which may have adjustable cross-sections through which the textile material to be treated is passed.
In the refining (degumming) of cotton yarn and cloth by a dilute alkali solution, batch operations employing an autoclave pressurized to 30-40 lbs. per sq. inch, at a temperature of 120-130 C., have been generally used. Recently, in the finishing, dyeing and heat treatment of textile material, it has been necessary to heat the said textile material to over 100 C. in the presence of water. For example, an autoclave is used in dyeing polyester fiber at a temperature of over 100 C. under pressure; in the heat treatment of spun polyvinyl alcohol fiber in the presence of water and ammonium sulphate saturated solution at a temperature of about 140-150 C. and pressure of about 40-60 lbs. per sq. inch; and also in the heat setting of nylon fabrics by pressurized steam at 140- 150 C. Staple fiber of viscose, after treatment by steam under pressure at 150-170" C., becomes quite hydrophobic, water absorption being almost the same as that of degummed cotton, and in view of other resulting improvements in quality, this treatment may be considered as cottonization of staple fiber. In the foregoing examples an autoclave has been used, but processing is not continuous, only batch operations being employed.
The present invention relates to an apparatus for auto clave treatment which makes possible continuous treatment, whereby the textile material may be processed continuously through the autoclave. According to the invention a pressure reducing nozzle is used at the inlet and outlet of the textile material with respect to the autoclave. The textile material can then be treated more practically in rope form, tow form or belt form, the large surface resistance to pressure leakage possessed by textile material being utilized to prevent leakage from the autoclave. A valve or a cock may be employed to control the internal area of the nozzle cross-section. Then by the combined effects of the said large surface resistance to pressure leakage and the control of crosssectional area of material passage, the textile material may be fed in and out of the autoclave continuously.
A more complete comprehension of the invention may be had from the following detailed description in conjunction With the accompanying drawing, wherein:
Fig. 1 is a diagrammatic view of a first form of the invention;
Fig. 2 is a similar view of a modified form;
Fig. 3 is a longitudinal sectional view of one form of nozzle valve which may be employed in the invention;
Fig. 4 is a transverse sectional view of the nozzle valve of Fig. 3;
Fig. 5 is a transverse sectional view of another form of nozzle valve; and
Fig. 6 is a longitudinal sectional view of the nozzle valve of Fig. 5.
Referring to the drawing, when a tow of man-made 2 fiber is passed through a nozzle on an autoclave, for example, and if pressurized fluid from the autoclave leaks past the fiber, the said fiber is sucked in at the point at which the speed of fiuid leakage is greatest. Thus parallel fibers of tow areseparated from each other and are distributed almost uniformly in the cross-sectional area of the nozzle, and consequently, when there is an adequate length of nozzle, the very large surface resistance of separated fibers to pressure leakage provides a sufiicient reduction in leakage to make continuous operation possible. For example, we have found that if 30-40 percent of the internal cross-sectional area of a nozzle is occupied by the sum of the cross-sectional area of filaments, continuous operation is possible, and with a nozzle length of 5-10 mm. it is possible practically to cut off a pressure of 50-80 lbs. per sq. inch.
In the treatment of cloth, the desired result may be obtained if the cloth passes through the nozzle in irregularly folded rope state or in simple rope form, but if the cloth passes througha rectangular nozzle in W-type folded state, i.e. in regularly zig-zag folded state, the pressure cutting is more constant and easier.
If a suitably designed valve or cock is used in the pressure cutting nozzle, the sectional area of the nozzle passage can be easily controlled during operation. This form of the invention particularly is effective if the cross-sectional area of rope form textile material changes, for example, at the connecting parts of two different tows or if different lots of textile materials to be finished have different cross-sectional area in rope form.
Illustration of drawings:
Fig. 1 illustrates pressure cutting by passing textile material through a simple nozzle or slit. Rope form textile material 1 passes through inlet pressure cutting nozzle or slit 2, then is treated in autoclave 3 by steam under pressure or solution 4, passes through turn rolls 5, and at last through outlet pressure cutting nozzle or slit 6, being continuously extruded to the exterior.
Fig. 2 illustrates the concept of pressure cutting by passing textile material through a nozzle or slit With a valve or cock. Textile material 1 passes through squeeze rolls 7, and inlet pressure cutting nozzle with valve or cock 8, and then over turn rolls 5, in autoclave 3, while being treated by pressure steamor solution 4, and at last through an outlet nozzle with valve or cock 9, being extruded continuously to the exterior. 10 denotes outlet squeeze rolls, and 11, 11' the inlet and outlet of the pressure steam or solution.
Fig. 3 and Fig. 4 illustrate in greater detail the valve to be mounted in the pressure cutting nozzle. 1 is the textile material, 12 the narrow nozzle, 13 the fixed inside of the nozzle, 14 the movable inside of the nozzle to control the cross-section of the nozzle, 15 a plug which can be moved up and down by the screw 16 connecting with turning bolt 17, 18 the stuffing box of the bolt, 19 a packing nut. and 20 the valve body. In the form shown in Fig. 5 and Fig. 6, 1 is the textile material, 21 the passage for the textile material, 22 the inside of the passage, 23 a rotatable plug which can control the cross-section area of the passage, 24 the exterior end of the plug, 25 the stufiing box of the plug, 26 a packing nut, and 27 the cock body.
