Description

Technical Field

[0001] The invention relates to the technical field of towel weaving, and in particular to a production method of an ultra-low-feathering double-sided fleece printed towel and the towel. Background Art

[0002] Printed towels on the market are mainly pure cotton products. Although pure cotton products have the characteristics of hygroscopicity, good air permeability and soft feel, they are relatively poor in durability, easy to shrink and deform, and are not resistant to friction, easy to snag and pill, and easy to tear. With the development of technology, polyester towels have gradually appeared on the market. Polyester towels have high strength and wear resistance, but relatively poor hygroscopicity and air permeability. In addition, while ensuring that the overall structure of the towel is not destroyed, the towel blanks after cutting are thicker, and the height of the pile loops is not less than 3mm. The suede effect is not ideal, and it cannot meet the market demand for ultra-thin, anti-snagging, etc., and is prone to snags and pulling. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, the purpose of the present invention is to provide a method for producing an ultra-low shedding double-sided velvet printed towel and a towel, which adopts a blended yarn of 70% polyester staple fiber and 30% polyester filament through a special warp knitting process, and adopts special velvet cutting equipment and technology, etc., to achieve an ultra-thin and anti-hooking appearance effect. At the same time, when printing, single-sided printing is performed, and the penetration of scraper pressure can achieve the effect of having patterns on both sides.

[0005] In order to achieve the above object, the technical solution of the present invention provides a method for producing an ultra-low shedding double-sided velvet printed towel, comprising the following steps:

[0006] S1, warp knitting technology is used to weave the blank towel, wherein the yarn is a blended yarn of 70% polyester staple fiber and 30% polyester filament; 11 heald frames are used, 1-2 are wool warps, 3 are selvedges, 4-5 are cut selvedges, 6-7 are selvedges, and 8-11 are ground warps; single strip weaving is used, and the space between strips is 1 cm; the ratio of the number of terry loops on the front and back is 2:1; two ground warps of the selvedge are on the top, and one ground warp is on the bottom, extending from the raised part to both sides, and the specific threading method is 1 lead 2 into 3T, 2 lead 2 into 4T, [1, 2 lead 3 into 2T, 2 lead 2 into 4T]*4+raised part+[2 lead 2 into 4T, 2, 1 lead 3 into 1T]*4, 2 lead 2 into 4T, 1 lead 2 into 3T;

[0007] S2, using a special pile cutting device to cut the warp knitted towel, the number of pile cutting times is 2-4 times, the special pile cutting device includes: a brush roller installed at the entrance of the frame; a pile cutting vertical knife assembly installed on the frame; a blower set on the frame; a pile cutting flat knife located behind the blower in the direction of travel of the towel; a blower, set in the blower, with multiple air outlets on the top surface of the blower; a suction fan, set on the top of the frame and corresponding to the position of the blower, the speed of the brush roller is 90rpm-100rpm, and the air volume of the blower is 7.5-8.5m 3 / s, outlet wind speed is 12-15m / s, and the air volume of the suction fan is 9.3-10.7m 3 / s, outlet wind speed is 20.4-26.5m / s;

[0008] S3, pre-treatment of the grey fabric, open width desizing, scouring, overflow whitening, softening, at least 2 cycles of treatment, at least 1 during the cutting process;

[0009] S4, pattern design, slurry mixing with disperse dyes, plate making, and printing;

[0010] S5, drying, steaming and washing, wherein the drying temperature is 100-140°C and the drying time is 10-30min; the steaming temperature is 110-120°C and the steaming time is 8-10min; the washing temperature is 90-98°C and the washing time is 15-30min.

[0011] The specially designed warp knitting process used in the present invention makes the warp and weft yarns of the towel more closely interwoven, the structure of the towel is more stable, not easy to deform, has good hygroscopicity, is soft and comfortable, and uses a blended yarn of 70% polyester staple fiber and 30% polyester filament, which has both wear resistance and high strength, and has certain wrinkle resistance and elastic recovery ability. In the specific method of wearing the selvedge, T is the reed tooth, and the number represents the number of the reed teeth. In the present invention, disperse dyes are used for sizing and printing. Disperse dyes can enter the interior of the fiber through the tiny pores on the fiber surface under high temperature and high pressure conditions to achieve effective printing and dyeing.

[0012] Preferably, when using special pile cutting equipment to cut the warp knitted towel, first cut it against the hair, then pre-treat the towel, then cut it along the hair, cut it against the hair, and cut it along the hair. After the double-sided pile cutting is completed, pre-treat the towel again.

[0013] Preferably, in the pre-treatment of the cloth, the open width desizing and bleaching are performed by hot washing at 80-100°C for 15 minutes; overflow whitening and softening are performed by using 30% hydrogen peroxide 30g / L, scouring agent YJ 20g / L, and supporting auxiliary agent KX-1042g / L at 98°C for 40 minutes, wherein the rolling rate is 85% and the steaming time is 30 minutes.

[0014] Preferably, the center plane of the vertical pile cut knife assembly perpendicular to the top surface of the flat pile cut knife is located at 1-4 mm from the front edge of the flat pile cut knife, and the speed is 350 rpm.

[0015] The brush roller of the present invention is equipped with many fine brushes, which can evenly lift up all the loops during operation, so that the loops stand upright and the pile is fully cut. Using a relatively low speed of 90rpm-100rpm, the fine brushes on the brush roller can make the fallen loops stand up completely, thus ensuring the pile cutting rate. The air volume of the blower is 7.5-8.5m 3 / s, outlet wind speed is 12-15m / s, and the air volume of the suction fan is 9.3-10.7m 3 / s, the outlet wind speed is 20.4-26.5m / s, which can be applied to the thin blank towel in the present invention, so that the blank towel can be infinitely close to the velvet cutting knife, which is beneficial to cleanly cut the terry loops on the surface. The central plane of the vertical velvet cutting knife assembly perpendicular to the top surface of the flat velvet cutting knife is located at 4mm from the front edge of the flat velvet cutting knife (when starting to cut the velvet, adjust the position according to needs, and the lowest can be adjusted to 1mm), and the left and right scales are adjusted to "0", and the speed is 350rpm, which is further beneficial to ensure the uniformity and flatness of the velvet surface. The velvet cutting knife position cannot be pressed too low at one time to avoid damaging and downgrading the product. Turn on the cloth feeding, move forward about half a meter, turn the cloth over to observe the velvet effect, adjust the knife position again to confirm, and then conduct formal velvet cutting. When cutting the pile, it is first cut against the hair, at this time, about 90% of the pile loops have been cut cleanly, and then the blank towel is pre-treated. After the treatment, there are still upright pile loops, and it is cut along the hair again. At this time, there are still about 2% of the pile loops that have not been cut cleanly, and it is cut against the hair again to make the pile loops 100% cut cleanly to the maximum extent, and the height of the pile loops is about 1-2mm. It can be cut along the hair again according to the situation. Based on the special warp knitting process and the specially designed pile cutting equipment and pile cutting process of the present invention, after the double-sided pile cutting, the tissue of the blank towel is still tight and firm, and the feather shedding rate is low, and the problems of hooking hair will not be caused.

[0016] The flat-width treatment can guarantee the flatness of the grey cloth to the greatest extent, but the fluffiness of the suede is slightly poor. The present invention combines the two processes of flat-width desizing and bleaching, overflow whitening and softening, and cycles the treatment for at least two times, which can reduce impurities to a minimum and achieve better flatness and fluffiness.

[0017] Preferably, in step S4, the mesh number of the plate making is 80-120.

[0018] Preferably, in step S4, printing is performed using a scraper printing machine, the number of printing times is 4-6 times, the pressure is 30-40 kg / m, and the scraper angle is 40-50 degrees.

[0019] The present invention is light and thin, and through the above printing method, it can achieve good printing effects on both sides, the reverse side has good permeability, and when the pattern penetrates downward, it does not spread to the surroundings, and the printing is uniform. In addition, the proportion of the lathe should be increased when the lathe is glued on the upper plate. Since the yarn woven towel blank towel used in the present invention is easy to slip compared with pure cotton products, in order to prevent the product from being loosely bonded at the guide belt, the conventional use proportion should be increased by 10-30%.

[0020] Preferably, the yarn specification is 150d-288f. Thus, the ultra-thin and anti-snagging appearance effect can be better achieved.

[0021] Preferably, in step S2, the number of times of cutting is 4, the speed of the brush roller is 100 rpm, and the air volume of the blower is 8.5 m 3 / s, outlet wind speed is 15m / s, and the air volume of the suction fan is 10.7m 3 / s, the outlet wind speed is 26.5m / s.

[0022] Therefore, the pile cutting effect can be better guaranteed, the pile loops can be cut 100% cleanly to the maximum extent, and the pile loop height is about 1-2mm.

[0023] The technical solution of the present invention also provides a towel obtained by using the ultra-low shedding double-sided velvet printed towel production method of any one of the above technical solutions, and the velvet loop height is 1-2mm.

[0024] The towel has high strength and wear resistance, is not easy to shrink and deform, and has good wrinkle resistance and good quick-drying properties. At the same time, it has certain moisture absorption and breathability, and can achieve an ultra-thin and anti-snagging appearance effect. The suede surface is uniform and beautiful, with a low feather shedding rate, and no snags or pulling.

[0089] As can be seen from Table 1, the towel product of the present invention has no hooking, low feather shedding, good water absorption, and all performance indicators are better than conventional pure cotton towel products. Compared with conventional polyester towel products, the towel product of the present invention has a very thin raw towel, a relatively uniform pile loop, a neat pile surface, and is not easy to hook. Figure 6 As shown, the left side is the towel product of the present invention, and the right side is the conventional polyester product. Moreover, under the condition of single-sided printing, the slurry can fully and evenly penetrate into the back side of the blank towel, forming a pattern effect on both the front and back sides, such as Figure 5 As shown. It not only simplifies the printing process, but also greatly improves the overall appearance of the product compared to conventional pure cotton towel products and conventional polyester towel products with one side having patterns and the other side being white.

[0090] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
