Technical Field

The invention relates to the technical field of textile technology, in particular to a sizing method for printing warps.

Background

In recent years, woven fabrics produced by warp printing have unique appearance style, the warp printing is to print on warp before the fabrics are formed, printing patterns are arranged on the warp through weaving, fabrics without patterns are arranged on weft, the warp printing fabric is mainly used for producing warp printing fabrics, the warp printing fabrics have unique style, the warp printing fabric has rich layering sense, has hazy color effect and dazzling bright spots of flowing light and color, and has the advantages of color change, different depths and overlapping from different angles and distances, and the warp printing fabric is similar to the 'ink accumulation' effect in the traditional ink-wash painting, thereby being generally popular in the market. Therefore, some enterprises and individuals have tried the warp printing production method of woven fabric. The method adopted at present comprises the steps of weaving a transitional cloth by warping warps, printing and steaming the transitional cloth, rewinding, removing woven wefts during weaving, and weaving again, but the process is fake and then prints yarns, so that the process flow is tedious and the operation is complex; the method also comprises the steps of adhering adhesive tapes on the upper partition sections of the warps to fix the warps, so that the warps are not easy to warp disorderly, and then printing on a silk printing machine; however, the printing methods are all carried out by using the traditional plate making process technology, and meanwhile, a transfer printing method is also used for carrying out transfer printing on warp yarns by using a transfer printing process, but the cold transfer warp beam printing mode of the fabric cannot achieve a good dyeing effect. The sizing machine is a large textile device for finishing sizing process, the sizing machine for pure sizing at home and abroad is developed more mature at present, and the tension control and the temperature control are very accurate. Sizing machines are of various types, but generally comprise a creel (bobbin creel), a sizing mechanism, a drying mechanism and a winding mechanism. The main part of the starching mechanism is a pulp tank, and the drying mechanism is also called a drying room.

In actual production, if yarns needing sizing are selected, warp printing and sizing are needed, and the common method is to firstly carry out warp printing and color fixing and then carry out sizing; because the sizing machine is also provided with a drying mechanism, sizing and warp printing can be synchronously finished, namely sizing and warp printing are firstly carried out, and finally the sizing machine is used for drying and color fixing by the drying mechanism; because the number of yarns dried by the sizing machine each time is less, the drying capability of the drying mechanism is relatively strong, and the sizing and warp printing combination is very suitable for sizing and warp printing. In the method, the warp is subjected to sizing and then printing, the printing effect is possibly influenced along with desizing of the fabric, so that the quality is reduced, in addition, if the dipping sizing is adopted, not only is the sizing waste and the cost increased, but also excessive sizing is caused to the warp, the sizing rate of the warp after the dipping sizing is too high, and the defect of hard and crisp hand feeling also exists.

Example 1

As shown in fig. 1, in order to realize printing on warp before the sizing process, and in this embodiment, synchronous production of warp printing and sizing is realized, warp printing effect and color fastness are improved, and a good coloring effect is achieved, so that the main processes in the weaving process flow include a spooling process, a warping process, a printing process, a color fixing process, and a sizing process, and the corresponding process devices include an unwinding device 100, a front expansion reed 200, a warp printing device 300, a baking device 400, a rear expansion reed 500, and a sizing device 600. Specifically, the unwinding device 100 rewinds the bobbin yarn from the twisting machine into a bobbin with a certain shape and a large capacity, and then the warping machine winds a certain number of warp yarns in parallel on the unwinding device 100 according to a specified length and width and a certain tension according to the process design requirement, and then the warp yarns are output in a reverse axial movement mode, and meanwhile, impurities, defects and dust on the yarns are eliminated, so that the productivity of the subsequent process is improved. And the effect of preceding telescopic reed 200 is to guarantee that the warp arranges evenly, the part of control sheet yarn breadth and sheet yarn location, there is very important effect to the quality of guaranteeing the warp beam, on traditional old-fashioned warper, the dent of telescopic reed is coarse, the tooth pitch is inhomogeneous and easily not hard up, it is inhomogeneous that the warp arranges often to appear, unevenness's phenomenon appears on the warp beam surface, and novel warper very much pay close attention to the surface finish quality of flexible dent and the precision of dent, and the cleanness of dent is heavily looked at very much, the width of the preceding telescopic reed 200 adjustment warp lamella that here set up in the stamp preamble. Further, the yarn rotary screen printing is adopted by the printing device 300, the printing mode is that color paste in the rotary screen is printed on the fabric under the driving of pressure by using a scraper, the rotary screen printing is different from other screen printing methods in several important aspects, the rotary screen printing is the same as roller printing and is a continuous process, and the printed fabric is conveyed to the lower part of a rotary screen printing cylinder which is in continuous motion through a wide rubber belt; the rotary screen printing device of the printing device comprises a rotary screen, a scraper, a pulp feeding device and the like, wherein the rotary screen is a pattern plate of the printing machine, is made of nickel metal and is also called a nickel screen, and is in a hexagonal mesh shape, two ends of the rotary screen are fixed by choke plugs so as to prevent the deformation of the rotary screen during printing and influence on the accuracy of the pattern, and can bear the pressure of the color paste and the scraper during printing; the scraper of the scraper rotary screen printing machine is arranged on a scraper frame on the central line of the rotary screen, the scraper frame is provided with both a scraper and a slurry feeding pipe, the scraper is made of chromium, molybdenum, vanadium and steel alloy, and the scraper has the characteristics of small friction coefficient and angle adjustment at will; during printing, the knife edge of the scraper is tangent to the inner circle of the rotary screen, the scraper mainly applies pressure to the color paste and scrapes the color paste as auxiliary composite action, and the pressure and the position of the scraper of the rotary screen printing machine can be adjusted to adapt to textile printing of various patterns and various thick and thin color pastes. Similarly, in the embodiment, roller printing, which is a high-speed process capable of producing printed fabrics with more than 6000 yards per hour, is also called mechanical printing, patterns in the roller printing are printed on the fabrics by engraving a copper roller or a roller, and the copper roller can be engraved with very fine lines which are closely arranged, so that very fine and soft patterns can be printed; for example, fine, dense Peezlii swirl tweed is a type of pattern printed by roller printing; the engraving of the cylinder is completely consistent with the design draft of a pattern designer, and each design color needs one engraving roller.

Further, the baking device 400 is a process after the printing device 300, and is a baking box, which can provide a proper baking temperature and time after being powered on to fix the color of the warp printed by the printing device 300, it should be noted that the color is located on the cloth, and further processing is needed to fix the color, the dye used as the printing colorant must be able to combine with the fiber, and the printed fabric can be fixed by placing in steam at a temperature close to or sometimes exceeding the boiling point of water (high-pressure steaming); this process is called steaming, so after steaming, the fabric is passed through a soap bath to remove the printing paste and other materials used in the mill base formulation, and finally the fabric is subjected to several washing and drying processes. Therefore, a large amount of water and heat energy are consumed in the printing process. Conversely, if a pigment, rather than a dye, is used in printing, the fabric is subjected to a dry heat treatment of up to about 210 ℃ to cure the resin fixing the coating, a process known as baking. And printing with pigments rather than dyes saves a lot of water and energy, the textile industry usually refers to fabrics printed with dyes as wet prints and fabrics printed with pigments as dry prints, since wet prints require steam steaming and subsequent water washing as part of the whole process; on the other hand, the printed cloth only needs to be dried and baked simply as a part of the coloring process, and does not need to be washed by water. Further, the rear expansion reed 500 can move the reed dent and adjust the width of the warp printed by the tooth pitch. In order to prevent dye liquor from permeating the fabric in the printing process of the textile, and to reduce warp breakage and improve weaving efficiency and grey cloth quality, the sizing device 600 needs to perform sizing treatment on the warp before weaving in order to prevent the warp from being broken due to large tension and friction during weaving of the woven fabric, enhance fiber adhesion and cohesion and form a firm sizing film on the surface of the yarn, so that the yarn becomes compact and smooth, and the breaking strength and abrasion resistance of the yarn are improved. The sizing agent is an indispensable procedure in the textile processing process, is also a very complicated and critical procedure, has poor sizing treatment, and can directly influence the weaving efficiency and the quality of products. In this example, the printing warp yarns were sized by a sizing machine and then woven.

The sizing device 600 in this embodiment further includes a slurry supply device 601, a spray tank 602, a size mixing barrel 603, a slurry delivery pipe 604, a slurry sprayer 605, and a press roll 606. Specifically, the warp after color fixing operation is input into a sizing device 600 through a rear expansion reed 500, and is sized through the matching of a size supply device 601 and a spraying size tank 602, and then is input into a drying device 700 to dry excessive moisture to form sized yarn, and a size mixing barrel 603 is arranged above the spraying size tank 602 and conveys size into a size sprayer 605 through a size conveying pipe 604 for sizing operation; the press roll 606 is provided in the spray tank 602 so as to form a slurry accumulation triangle, and the slurry is infiltrated into the yarn by extrusion, thereby completing the sizing process.
