- U SC is a structural parameter to characterize the new tube designs, designating the percent of total dye transferable area to the total tube surface area.
- Dye effluent directly flows to areas of wound yarn body which are befitted on the hollow areas of the tube surface, maintaining better dye pick up than areas of wound yarn body which are befitted on the solid areas of the tube surface.
- dye solution flows along the yarn layers and run out at the lowest yarn layer of the wound yarn body through the hollow areas of tube surface.
- contact time of dye effluent and yarn layers are longer than those contact time of the hollow areas of the tube. Because of the contact time difference of the wound yarn areas, color deepness differences occur along yarn length. Color deepness differences may reach up to 3 % to 5 % of the defected yarn in yarn dye houses.
- Another aspect of the low U SC value of the current tubes is higher time requirement for dyeing and drying processes of the yarn packages. Circulation of dye effluent and hot air through surface hollows of the tube is also low resulting low U SC value of the tubes. Low dye effluent and air circulation area require longer dyeing and drying time. Therefore yarn package dyeing and drying efficiency becomes lower.
- Structural shape of currently used commercial plastic tubes is easily deformed and descended in the middle of the tube body as result of the normal pressure resulting of dyeing and drying processes. Such deformation decreases the lifetime of the tube.

- collected dye liquid flows and drained to innerside of the yarn package through hollow areas (14) of the net (11) to the hollow areas (6) of the main body and hollows of the flanges (8). If the dye liquid is feed from the outside of the yarn package, dye liquid moves inside of the yarn layers quickly, and absorbed by the yarn layers. Over fed dye liquid flows through hollow areas (14) of the plastic net (11) to hollow areas (6) of the tube and hollows (17) of the supporting disk(7). Therefore effective and quick circulation of dye liquid through inner structre of yarn package is completed.
- Proposed tube minimizes contact surface of the lowest yarn layers and solid parts of the tube, does not allow any dye liquid collection between the intersection surface of lowest yarn layers and ribbings (12) and (13) therefore constitution possibilty of deeper color dyeing defects on the lowest yarn layers is minimized. Color difference among layers of yarn package is therefore eliminated. Such improvement on the color shade difference of the yarn can not be provided neither by the elevated ribbings of the patent DE 10 56 569 B tube structure nor the spaced uprights of the patents US-A-3 882 698 tube structure.

Increased U SC value of proposed tube provides better dye effluent flow efficiency, by the help of 1.6 to 2.5 times increased dye effluent flow surface areas comparing the current commercial tubes. Enlargement of dye effluent flow area of the tube enable to decrease dyeing and drying time and pumping pressure requirements, therefore energy requirement is decreased with increased efficiency. Tube structures defined in the patents of SU1832778A1 and TR200601193Y provide U SC value of 0,85 while still having above mentioned disadvantages.

Abstract
Description
- The invention concerns a plastic tubular body used during the dyeing and finishing procedure of yarn packages. The new tube improves dyeing quality reduces yarn waste and time requirement of dyeing and drying processes. Therefore the invention provides increased productivity, and savings on time and energy consumption of the dyeing process.
- It is important to mention the "Useful Surface Coefficient" (USC) parameter to evaluate the performance of the dyeing tubes.
- Useful Surface Coefficient (USC) is defined as rate of total hollow area on the surface of the tube (SH) to the total yarn winding surface area (ST).
USC = SH / ST or % USK = (SH / ST) 100 - USC is a structural parameter to characterize the new tube designs, designating the percent of total dye transferable area to the total tube surface area.
- Currently available plastic yarn tubes are designed to comprise a tubular or conical body having different shaped hollow areas on their surfaces and the dye effluent is pumped to the yarn package from inside of the tube. The USC value (ratio of total hollow area of the tube surface to total yarn winding surface area of the tube) has been determined quite low for the current commercial tubes. Investigations about the USC of commercial available tubes has shown that USC value has changed between 0.28 - 0.55. Low USC value of the current tubes is one of the reasons for dyeing inaccuracy on the lower layers of the wound yarn body on the packages. Considering the inside through outside dye effluent flow dyeing process, direct contact of dye effluent and the lowest yarn layer of the wound yarn body is only limited by the hollow surface area of the tube. Dye effluent directly flows to areas of wound yarn body which are befitted on the hollow areas of the tube surface, maintaining better dye pick up than areas of wound yarn body which are befitted on the solid areas of the tube surface. Considering the outside through inside dye effluent flow dyeing process, dye solution flows along the yarn layers and run out at the lowest yarn layer of the wound yarn body through the hollow areas of tube surface. On the solid areas of the tube body, contact time of dye effluent and yarn layers are longer than those contact time of the hollow areas of the tube. Because of the contact time difference of the wound yarn areas, color deepness differences occur along yarn length. Color deepness differences may reach up to 3 % to 5 % of the defected yarn in yarn dye houses.
- Another aspect of the low USC value of the current tubes is higher time requirement for dyeing and drying processes of the yarn packages. Circulation of dye effluent and hot air through surface hollows of the tube is also low resulting low USC value of the tubes. Low dye effluent and air circulation area require longer dyeing and drying time. Therefore yarn package dyeing and drying efficiency becomes lower.
- Structural shape of currently used commercial plastic tubes (especially cylindrical ones) is easily deformed and descended in the middle of the tube body as result of the normal pressure resulting of dyeing and drying processes. Such deformation decreases the lifetime of the tube.
- Similar inventions are explained in the patents of Russia (former Soviet Union
SU1832778A1 TR 2006 01193Y -
SU 1832778 A1 - Patent of
TR 2006 01193Y - Although USC value of both patents described above is around 0.80-0.90. they are not practically usable in the yarn dye houses. Manufacturing of the tubes is time consuming process because of several distinct parts and requirement of extra fixing process of the screen clotting to the main body. Equipment used for the fixation of screen clothing is also affected by the dyeing conditions and it can be oxidized, resulting color degradation of the yarn in some layers of the yarn package. Another disadvantage of the proposed tube is about screen clothing which causes wearing of winding drum. Worn off surface of the drum causes increased number of yarn breakage during the winding of yarn package.
- Main aims of the proposed invention are to improve dyeing quality of yarn packages, to reduce yarn waste of dyeing defects, to increase dyeing and finishing efficiency of the yarn packages, provide energy savings.
- The invention comprises a plastic tubular body and a plastic net placed around the tubular surface of the plastic body; the plastic net's surface enables to uptake high dye flow rate (high value of USC) and material of the net has high rigidity property to bending and inflection.

- Tubular body of the tube (1) shown in
FIG.1, FIG.2 ,FIG.5, and FIG.7 comprises first (2) and second (3) flanges having circumferential hollows (8), longitudinal (4), circumferential (5) ribbing of tubular body, hollow areas of main body (6), supporting disk (7) placed between flanges (2) and (3) at equal distances, and hollow places (17) of supporting disk Plastic net (11) is fixed on to the tubular body. Fixation of the plastic net onto the tubular body is completed by the help of transverse grooves of the first flange (9), and grooves (10) of second flange inner diameter. - Plastic net (11) of the tube is shown in
FIG.4 ,FIG.5, FIG.6, and FIG.7 and comprises circumferential (12) and longitudinal (13) ribbings and rectangular hollows (14) constituted by intersections of ribbing (12) and (13). Inner circumference of net left and right edges comprise notches (15) and (16). Fixation of the net onto the tubular body is completed by nesting of notches (15) to the grooves (9) of first flange and notches (16) to the grooves (10) of second flange. Width of the net ribbings is not wider than 1.5 mm and depth thickness of net ribbings is not more than 3 mm. - Utilization of the high performance plastic tube:
- A regular yarn package winding machine is equipped with the proposed tube, required amount of yarn is wound onto the tube at desired density and wound yarn package is sent to the package dyeing machine. Yarn packages are placed onto the perforated cylinder of the dyeing machine tank. Second flange (3) (becomes bottom edge flange) of the yarn package is nested to the first flange (2) (becomes upper edge flange) of the below yarn package. After completing the yarn package placement of the dye tank, dyeing process is started.
- Dye effluent is pumped through wound lavers of yarn packages from the inside of the tubes, starting from the hollow areas (6) of the tubular body (1), hollow areas (14) of the net (11) and bottom layers of the yarn wounds. When the pumping of dye effluent from inside to outside of the yarn package is stopped, collected dye liquid flows and drained to innerside of the yarn package through hollow areas (14) of the net (11) to the hollow areas (6) of the main body and hollows of the flanges (8). If the dye liquid is feed from the outside of the yarn package, dye liquid moves inside of the yarn layers quickly, and absorbed by the yarn layers. Over fed dye liquid flows through hollow areas (14) of the plastic net (11) to hollow areas (6) of the tube and hollows (17) of the supporting disk(7). Therefore effective and quick circulation of dye liquid through inner structre of yarn package is completed.
- Proposed tube minimizes contact surface of the lowest yarn layers and solid parts of the tube, does not allow any dye liquid collection between the intersection surface of lowest yarn layers and ribbings (12) and (13) therefore constitution possibilty of deeper color dyeing defects on the lowest yarn layers is minimized. Color difference among layers of yarn package is therefore eliminated. Such improvement on the color shade difference of the yarn can not be provided neither by the elevated ribbings of the
patent DE 10 56 569 B tube structure nor the spaced uprights of the patentsUS-A-3 882 698 tube structure. - Employment of supporting disk (7) between flanges (2) and (3) provides long life to the tube, maintaining higher resistance to bending and deformation of the tube against high stress loads of dyeing and drying processes of the yarn packages. Such resistance properties are not provided by the
DE 10 56 569 BUS 2004 /016842 A1 andUS-A-3 882 698 . - Useful Surface Coefficient (USC) value of the proposed tube is increased to the 0.85 from the 0.28-0.55 value of current commercial tubes and also tubes defined in the patents of
DE 1056569 B .US 2004 / 016842 A1 andUS A-3 882 698 . Improvement of USC value is warranted by the use of introduced tubular body and net structures. Increased USC value of proposed tube provides better dye effluent flow efficiency, by the help of 1.6 to 2.5 times increased dye effluent flow surface areas comparing the current commercial tubes. Enlargement of dye effluent flow area of the tube enable to decrease dyeing and drying time and pumping pressure requirements, therefore energy requirement is decreased with increased efficiency.
