Description

Technical Field

[0001] The invention belongs to the technical field of textile dyeing and finishing equipment, relates to a new structure and new quality of cotton or cotton-containing fabrics, and relates to a fully mercerized new fabric and an automatic amplitude modulation and expansion mercerizing machine. Background Art

[0002] Mercerizing machine equipment uses concentrated alkali to expand cotton, polyester-cotton and other cotton-containing warp and weft fibers, with a maximum expansion rate of up to 27%. At the same time, it uses external force to stretch the fiber to change the fiber shape, making the longitudinal shape of the fiber flat and ribbon-like, removing the natural fiber and giving the fiber an additional cohesive force; the processed fiber cross-section is irregularly oval, with strip-shaped central cavity holes or points, the fiber surface is directional, presents a silk-like luster, stable size, durable luster, and improved dye adsorption capacity. At the same time, it also improves the fiber's physical properties such as strength, elongation and elasticity.

[0003] In the production process of the existing mercerizing machine, in the concentrated alkali area, the cloth can only produce semi-mercerized cloth in the 180-230g / L concentration of alkali solution. The chemical reaction between the cloth and the alkali is not sufficient, the fiber expansion rate is less than 15%, and wrinkles are easily produced; in the de-alkali area, the cloth clips are subjected to large forces on the two sides of the cloth when the cloth clips are stretched, and the force in the middle is small, resulting in uneven warp and weft densities in the same range, and in severe cases, wood ear edge defects are produced; bent roller mercerizing can produce thin fabrics, which will produce warp and weft line crescent-shaped defects; when straight roller mercerizing produces wide cloth, the large diameter roller has too large warp tension, which destroys the structure of the warp and weft fiber, and also produces wood ear edge defects, and the cloth width often has different weft dimensions.

[0004] At present, in order to prevent wrinkles from being generated when the cloth shrinks due to alkali, the warp tension of the cloth guide roller is increased, but the weft tension cannot be provided. This causes the warp structure of the cloth fiber to become a flat and long ellipse after mercerization. At this time, the roundness of the pores in the cross-section of the warp and weft fibers of the cloth is not sufficient, and the produced cloth has poor gloss, poor adsorption, poor strength and poor wear resistance. After dyeing, the cloth will have defects such as color difference and fading. Summary of the invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a fully mercerized new fabric and an automatic amplitude modulation and expansion mercerizing machine, which can be used at any time through the automatic amplitude modulation device to adjust the rotation angle of the active and passive expansion rollers in the concentrated alkali box, the medium alkali box, and the light alkali box within the range of 0 to 240 degrees, and the cloth is set to the roller surface covering area of ​​0 to 180 degrees. When the weft and weft movement of the guide wheel guide groove fixed on the shaft to the arc slide is 0 to 180 degrees, the expansion amount is n, and when the shaft rotates to 60 to 240 degrees, the expansion amount is 0.666n, thereby realizing adjustable expansion amount, realizing that any fabric width and density can quickly penetrate into the interior of the fabric in 260 concentrated alkali solution, so that the cloth obtains a fully mercerized fabric with a warp and weft fiber cross-sectional structure tending to a roundness rate of 70 to 90.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1 , Figure 2 and Figure 5 - Figure 7 As shown, the automatic amplitude-adjusting active expanding roller comprises:

[0036] A central shaft 17 is fixedly connected to a pair of first guide wheels 11 and at least one pair of second guide wheels 8, the first guide wheels 11 are sleeved with a first inner roller 15 on the outside, both ends of the central shaft 17 are sleeved with a sleeve 9 and a second inner roller 10 in sequence from the inside to the outside, a second guide wheel 8 is sleeved with a second inner roller 10 on the outside, and the second guide wheel 8 and the second inner roller 10 are arranged on the central shaft 17 in pairs, and the second inner roller 10 and the first inner roller 15 are connected by a saw. The central shaft 17 is connected by teeth, a pair of gear sleeves 13 are fixedly arranged on the left and right sides, and the gear sleeve 13 is sleeved with a second gear 14 connected to the second inner roller 10 on the outside, and the first inner roller 15 is provided with an arc T-shaped track, and an arc slide 7 for weft shift is slidably connected through the arc T-shaped track, and a plurality of arc slides 7 are arranged along the circumference of the outer wall of the first inner roller 15 and the second inner roller 10, and the end of the central shaft 17 is sequentially provided with an alkali box 5 and a shaft seat 4 fixedly installed on the alkali box 5 from the outside to the inside;

[0037] A first short shaft 16 is arranged at one end of the central shaft 17 and connected to the central shaft 17 through a cross connector 21. An end cover 6, a first gear 2 and a second bearing seat 3 are sequentially sleeved on the first short shaft 16 from outside to inside, and the second bearing seat 3 is fixedly connected to the alkali box 5;

[0038] A guide column 12 is fixedly connected to the end of the arc-shaped skateboard 7. Multiple guide columns 12 are arranged in the guide grooves of the second guide wheel 8 and the first guide wheel 11, and the guide grooves of the second guide wheel 8 and the first guide wheel 11 are inclined outward. The front semicircular linear feature of the guide grooves of the second guide wheel 8 and the first guide wheel 11 is that a vertical oblique line is arranged between two vertical lines, and the rear semicircular linear feature is that a vertical oblique line and a vertical line are arranged between two vertical lines, and the linear trajectory of the front semicircular guide groove is opposite to the linear trajectory of the rear semicircular guide groove. Two first guide wheels 11 and two second guide wheels 8 are each provided, and the two first guide wheels 11 and the second guide wheels 8 are both arranged at two ends of the central axis 17, and the guide grooves of the two first guide wheels 11 are inclined in opposite directions, and the guide grooves of the two second guide wheels 8 are inclined in opposite directions.

[0039] When external power is transmitted to the second gear 14 through a pair of bridge gears 47, the second gear 14 drives the first inner roller 15 and the second inner roller 10 to rotate, and drives the arc T-shaped track of the first inner roller 15 and the second inner roller 10 of the arc-shaped slide plate 7 to move in the weft direction. At the same time, the guide column 12 at one end of the arc-shaped slide plate 7 makes a circular motion inside the wheel groove of the first guide wheel 11 and the second guide wheel 8. At this time, the left and right arc-shaped slide plates 7 move outward in the weft direction. When the cloth is at 0-180°, the guide grooves of the left and right first guide wheels 11 and the two second guide wheels 8 are tilted outward at a certain angle. When the left and right arc-shaped slide plates 7 move outward, the cloth wrapped on the arc-shaped slide plate 7 gradually expands outward. At this time, the area of ​​the cloth on the roller surface gradually increases, and the concentrated alkali quickly penetrates into the cloth. At this time, after the cloth sample is inspected by electron microscope of the dropped cloth, the analysis shows whether the roundness of the warp and weft fiber cross-section structure reaches 70% to 90%, and whether the barium value, expansion rate and roundness data meet the requirements of sufficient mercerization. The active and passive expanding rollers are rotated by the automatic amplitude modulation device, and the electronic angle display screen 53 is used to observe and record. In the range of 0 to 240 degrees, the cloth-to-roller surface covering area is 0 to 180 degrees. When the guide groove of the guide wheel fixed on the shaft moves the arc-shaped slide plate in the weft and weft directions at 0 to 180 degrees, the expansion amount is n, and when it is 60 to 240 degrees, the expansion amount is 0.666n, thereby realizing adjustable expansion amount, adjusting at any time and ensuring that the weft expansion amount of the active expanding roller arc panel to each square inch of the cloth surface is uniform and consistent.

[0040] See also Figure 3 - Figure 7 As shown, the automatic amplitude-adjusting passive widening roller comprises:

[0041] The central shaft 17 is provided with a pair of first guide wheels 11 and at least one pair of second guide wheels 8 fixedly connected thereto. The first inner rollers 15 are sleeved on the outer sides of the pair of first guide wheels 11. The central shaft 17 is sleeved with a sleeve 9 and a second inner roller 10 in sequence from the inside to the outside. The outer side of one second guide wheel 8 is sleeved with a second inner roller 10. The second guide wheel 8 and the second inner roller 10 are arranged on the central shaft 17 in pairs. The second inner roller 10 and the first inner roller 15 are connected by a sawtooth. The first guide wheel 11 and the second inner roller 10 are sleeved with a sleeve 9 and a second inner roller 10 in sequence from the inside to the outside. Bearings 23 are provided between the first inner rollers 15 and between the second guide wheel 8 and the second inner roller 10. A circular arc T-shaped track is provided on the first inner roller 15, and a curved slide 7 for weft shift is slidably connected through the circular arc T-shaped track. A plurality of the curved slides 7 are arranged along the circumference of the outer wall of the first inner roller 15 and the second inner roller 10. The end of the central shaft 17 is provided with an alkali box 5 and a shaft seat 4 fixedly installed on the alkali box 5 in sequence from the outside to the inside. A third shaft sleeve 18 sleeved on the central shaft 17 is provided between the shaft seat 4 and the second guide wheel 8.

[0042] The second short shaft 22 is arranged at one end of the central shaft 17 and connected to the central shaft 17 through a cross connector 21. The second short shaft 22 is sleeved with a first bearing seat 1, a worm wheel 20, a first gear 2 and a second bearing seat 3 in sequence from the outside to the inside, and the second bearing seat 3 is fixedly connected to the alkali box 5. The worm wheel 20 is meshedly connected with a worm 19;

[0043] A guide column 12 is fixedly installed at one end of the arc-shaped skateboard 7. A plurality of guide columns 12 are arranged in the guide grooves of the second guide wheel 8 and the first guide wheel 11, and the guide grooves of the second guide wheel 8 and the first guide wheel 11 are inclined outward. The front semicircular linear feature of the guide grooves of the second guide wheel 8 and the first guide wheel 11 is that a vertical oblique line is arranged between two vertical lines, and the rear semicircular linear feature is that a vertical oblique line and a vertical line are arranged between two vertical lines, and the linear trajectory of the front semicircular guide groove is opposite to the linear trajectory of the rear semicircular guide groove. Two first guide wheels 11 and two second guide wheels 8 are each provided, and the two first guide wheels 11 and the second guide wheels 8 are both arranged at two ends of the central axis 17, and the guide grooves of the two first guide wheels 11 are inclined in opposite directions, and the guide grooves of the two second guide wheels 8 are inclined in opposite directions.

[0044] When the cloth passes through the passive expansion roller, it will drive the passive expansion roller to rotate. At this time, one end of the arc-shaped slide plate 7 arranged on the outer periphery of the roller will rotate inside the guide groove of the guide wheel. Since the guide grooves of the guide wheels at the left and right ends of the central axis 17 are inclined in opposite directions, the arc-shaped slide plates 7 on the left and right sides will move in opposite directions. The arc-shaped slide plate 7 moves in the weft direction through the guide rail on the inner roller and drives the inner roller to rotate. During the rotation, the cloth gradually expands along with the arc-shaped slide plate 7, so that the area of ​​the cloth attached to the roller surface increases, causing the density of the warp and weft fibers of the cloth to change from dense to sparse, expanding the gaps between the fibers of the cloth, and helping the concentrated alkali to quickly penetrate into the cloth fibers, so that the cloth is fully swollen, and a completely sufficient mercerized fabric is generated after a full chemical reaction.

[0045] See also Figure 8 - Fig. 9 As shown, a fully mercerized new fabric and an automatic amplitude modulation and expansion mercerizing machine, comprising:

[0046] A front cloth rack 31, one side of which is provided with a first concentrated alkali box 33, a first three-roller re-roller 48, a second concentrated alkali box 36, a third concentrated alkali box 37, a second three-roller re-roller 50, a first medium alkali box 38, a first medium-sized three-roller car 39, a second medium-sized alkali box 40, a weak alkali box 41, and a second medium-sized three-roller car 42. A flat washing box 43 is provided on the side of the second medium-sized three-roller car 42. A plurality of two-roller cars 44 and cloth guide rollers 45 are intermittently provided inside the flat washing box 43. A drying drum roller 46 is provided on the side of the flat washing box 43. A rear cloth rack 52 is arranged on the side of the drying drum roller 46, and the first concentrated alkali box 33, the second concentrated alkali box 36, the third concentrated alkali box 37, the first medium alkali box 38, the second medium alkali box 40 and the light alkali box 41 are all provided with active widening rollers 32, passive widening rollers 34 and a bridge transmission shaft connected to the motor power on the alkali box, a transmission gear 47 is fixedly connected to the bridge transmission shaft, and is connected to the second gear 14 on the active widening roller 32 through the transmission gear 47, and a grid cloth roller 49 is connected to the top of the first three-roller re-rolling 48 and the second three-roller re-rolling 50.

[0047] As can be seen from the above, the cloth enters the first concentrated alkali box 33 from the front cloth rack 31 in turn, the alkali concentration is 270g / L, and passes through the active widening roller 32 and the passive widening roller 34 in the first concentrated alkali box 33. Then, the cloth passes through the first three-roller re-rolling 48 and enters the second concentrated alkali box 36, the alkali concentration is 270g / L, and passes through the active widening roller 32 and the passive widening roller 34 in the second concentrated alkali box 36. Then, the cloth is wound on the grid cloth roller 49 and laid on the concentrated alkali box and the grid cloth roller 49. The total length of the cloth on the 9 is 90 meters. When the speed is 70 meters / minute, the time condition for the cloth to fully react with the alkali solution is met, and then the cloth is wound into the third concentrated alkali box 37. The cloth wound out of the third concentrated alkali box 37 passes through the second three-roller re-rolling 50 and enters the first medium alkali box 38. The alkali concentration is 50-60g / L, and the alkali solution temperature is 70-90 degrees. The cloth is wound around the active widening roller 32 and the passive widening roller 34 inside the first medium alkali box 38, and then the cloth passes through the first medium three-roller 3 9 Enter the second alkali medium box 40, bypass the active widening roller 32 and the passive widening roller 34 inside the second alkali medium box 40, and then enter the weak alkali box 41, the alkali concentration is 5g / L, the alkali solution temperature is 90-100 degrees, and bypass the active widening roller 32 and the passive widening roller 34 inside the weak alkali box 41. After the weft dimension is stable, the cloth enters the flat washing box 43 through the second medium-sized three-roller 42. The pH value inside the flat washing box 43 is 7-8, and bypasses the two-roller roller in turn. 44 and cloth guide roller 45, and finally pass through drying drum roller 46 and rear cloth rack 52. When the cloth passes through the concentrated alkali box, it can fully react chemically with the alkali solution with a concentration of 260-280g / L at room temperature for 35-40S. When it passes through the medium alkali box with a concentration of 50g / L, the cloth achieves weft dimension stability and the internal structure of the cloth is fixed. Adding a light alkali area can reduce the alkali solution concentration on the cloth to below 5g / L, and the concentrated alkali is removed quickly and thoroughly in a short time.

[0048] Every three active widening rollers 32 and one passive widening roller 34 form a column of amplitude modulation components. A first gear 2 connected to a transition pinion 51 is provided between the active widening rollers 32 in each column and between the active widening rollers 32 and the passive widening rollers 34. Every two columns of amplitude modulation components form a group of automatic amplitude modulation mechanisms. The shaft 17 of the passive widening roller 34 at the bottom of each group of automatic amplitude modulation mechanisms is connected to the worm wheel 20 and the worm 19 through the first gear 2 on the short shaft 22. The end of the short shaft 22 is connected to a mounting frame 35 supported on the ground. The end of the first gear 2 of the uppermost active widening roller 32 of each group of automatic amplitude modulation mechanisms is fixedly connected to an electronic angle display screen 53 for measuring the rotation angle of the active widening roller 32. The two columns of amplitude modulation components form a group of automatic amplitude modulation mechanisms for adjustment. After the cloth sample is inspected by an electron microscope according to the falling cloth, the cross-sectional structure of the warp and weft fibers is analyzed and displayed. Whether the roundness reaches 70% to 90%, analyze whether the barium value, expansion rate, and roundness data meet the requirements of full mercerization, use the electronic angle display screen 53 to observe and record, within the range of 0 to 240 degrees, the cloth-to-roller covering area is 0 to 180 degrees, when the guide wheel guide groove fixed on the shaft moves the arc-shaped slide plate in the weft direction at 0 to 180 degrees, the expansion amount is n, and when it is 60 to 240 degrees, the expansion amount is 0.666n, so that when the guide column of the arc-shaped slide plate makes a circular motion in the guide wheel guide groove, the weft movement amount of the arc-shaped slide plate can be changed at any time, and any cloth density and width requirements can be met to adjust at any time and ensure that the weft expansion amount of the active and passive expansion roller arc panels to the cloth surface per square inch is uniform, and the angle and expansion amount data required for each specification of cloth can be recorded and filed, and a fabric with a barium value greater than 150, a expansion rate greater than 27%, a warp and weft fiber roundness rate between 70 and 90, and full and full mercerization is obtained.

[0051] Reference Figure 8 and Fig.10 The mercerizing machine can arbitrarily combine the active widening roller 32 and the passive widening roller 34 according to different needs of users, such as Fig.10 In the alkali box 38, a pair of bridge transmission gears 47 are arranged to mesh with the second gears 14 of a pair of active widening rollers 32, and the automatic amplitude modulation structure is arranged outside the alkali box to change the path of the cloth in the alkali box, realize the diversity of cloth and alkali removal methods, and the high alkali removal efficiency, thereby preventing the wide cloth from producing wood ear edges and inconsistent weft dimensions.

[0052] The automatic amplitude modulation active and passive expanding rollers can be manufactured in two ways: sliding friction and rolling friction, with sliding friction being the main method. Alkali solution is the best lubricant. The structural modification of the inner roller with a diameter of more than 300mm is more applicable, the weft amplitude modulation amount is doubled, the service life is longer, the guide wheel diameter is increased, the guide groove weft displacement is increased, and the diameter of the two ends of the guide wheel and the inner roller is increased. The sliding friction service life in alkali solution is longer; the contact area between the weft track on the arc slide and the weft track on the inner roller is increased, and the service life is increased; the surface of the arc slide is covered with a 3x3mm rectangular toothed panel, which increases the friction between the cloth and the arc slide.

[0053] The original features are retained, including multi-section inner rollers, multi-guide wheel structure, and multi-section arc-shaped slide plate structure. With the increase of internal stress support points on the shaft, the tensile and bending resistance of the shaft, inner rollers, and arc-shaped slide plate is greater.

[0054] The invention can manufacture automatic amplitude modulation active and passive expanding rollers and automatic amplitude modulation expanding roller mercerizing machines with one shaft, three inner rollers, four guide wheels and four arc-shaped slide plates, one shaft, five inner rollers, six guide wheels and six arc-shaped slide plates, and one shaft, seven inner rollers, eight guide wheels and eight arc-shaped slide plates, eight kinds of door width mercerizing machines with a range of 1600 to 3600 mm, a machine speed of 60 to 80 m / mi s, a total length of 48 to 55 m, and optional grid cloth rollers; it can create full mercerization and new structural quality standards for pure cotton and cotton-containing fabrics, knitted fabrics, denim fabrics, curtain fabrics, and bedding fabrics; through the invention, the roundness of the two cross-sections of the fabric fibers can be set to judge 20%, 30%, and 40% as unqualified products, 50%, 60% as qualified products, and 70%, 80%, and 90% as high-value premium products.

[0055] Various combinations of plain, serpentine and satin, also known as the three primary structures, various structures, densities and widths of fabrics, can be produced and processed by the automatic amplitude-adjusting and expanding roller mercerizing machine to achieve fully mercerized fabrics with a bulking rate of 27% and a barium value of more than 150, as well as fully mercerized fabrics with a cross-sectional circularity of the warp and weft fibers of 70-90%.

[0056] It is analyzed that under the action of the synchronous motor, the active expanding roller itself plays a synchronous role, does not generate warp tension, can control the warp tension of the cloth, reduce the effect of the warp tension on the cloth, and make the combined force of the warp and weft tensions produce an expanding effect on the cloth, which can achieve the function of the warp and weft tensions tending to balance. Under the combined force of the warp and weft tensions, the cloth surface gradually expands, the area gradually increases, the density changes from dense to sparse, the warp and weft structure of the cloth fibers obtains uniform force, and the warp and weft cross-sections of the fibers tend to be round. The concentrated alkali quickly penetrates into the interior of the cloth fibers, making the fiber expansion rate the highest. After a certain period of chemical reaction, the cloth achieves full mercerization and the cross-sections of the warp and weft fibers tend to be 70% to 90% round.

[0057] The passive expansion roller can generate both warp force and weft force, which can increase the warp force function and give the cloth fiber appropriate tension during mercerizing to obtain better gloss.
