Description

Technical Field

[0001] This invention relates to the field of towel weaving technology, specifically to a single-sided jacquard towel and its weaving process. Background Technology

[0002] The standard manufacturing process for towels is warping, weaving, and finishing. Warping involves warping the yarn onto two warp beams, one as the ground warp and the other as the pile warp. Then, the two warp beams are joined with the yarns on a multi-arm loom or jacquard loom, and the standard towels are woven using the weft yarns and weaving process. Finally, the towels are finished by finishing the process.

[0003] Currently, there are two main woven processes for towels: the first is to weave first and then dye, specifically warping, sizing, weaving, post-treatment, and finishing (sewing, inspection, and packaging); the second is to dye first and then weave, specifically yarn dyeing, warping, sizing, weaving, post-treatment, and finishing (sewing, inspection, and packaging).

[0004] The specific process of weaving before dyeing is as follows:

[0005] Warping: According to the warping process, a certain number of yarn bobbins are hung on the warping frame. The yarn is pulled onto the square bobbin by the tension of the winding beam and wound into a beam.

[0006] Sizing: The square spool of yarn is placed on the sizing rack according to the process requirements. Then, the yarn passes through the sizing tank and drying room and is wound onto the warp beam. After the sizing process, the strength and abrasion resistance of the yarn are greatly improved, making the yarn meet the necessary conditions for weaving on a loom.

[0007] Weaving: The sized warp beams (wool warp beams and ground warp beams) are fixed on the warp beam frame of the towel loom, and the yarns on the warp beams are joined with the yarns on the loom. Then, the towel fabric is woven according to the requirements of the weaving process.

[0008] Post-processing: The raw fabric is boiled, bleached, dyed (or whitened) to make the towels meet the requirements of hand feel, water absorption and appearance. Some can also be printed according to the needs of the pattern.

[0009] Post-processing (sewing, inspection and packaging): The towels that have undergone post-processing have become usable. After being cut, sewn and inspected, the towels are packed into boxes.

[0010] The specific process for dyeing and then weaving towels is as follows:

[0011] Dyeing: The raw yarn is boiled, bleached and dyed using a tube dyeing machine, so that the yarn has a certain color before weaving, making it easier to weave towels of different colors.

[0012] Warping: According to the warping process, the dyed yarn bobbins are hung on the warping frame, and the yarn is pulled onto the square spool by the tension of the winding beam and wound into a beam.

[0013] Sizing: The square spool of yarn is placed on the sizing frame according to the process requirements. Then, the yarn passes through the sizing tank and drying room and is wound onto the warp beam. After the sizing process, the strength and abrasion resistance of the yarn are greatly improved, making the yarn meet the necessary conditions for weaving on a loom.

[0014] Weaving: The sized warp beams (wool warp beams and ground warp beams) are fixed on the warp beam frame of the towel loom, and the yarns on the warp beams are joined with the yarns on the loom. The towel fabric is woven according to the requirements of the weaving process.

[0015] Post-processing: The raw fabric is desized, washed, and softened to ensure that the towels meet the requirements for hand feel, water absorption, and appearance. Some may also be printed according to the pattern requirements.

[0016] Post-processing (sewing, inspection and packaging): The towels that have undergone post-processing have become usable. After being cut, sewn and inspected, the towels are packed into boxes.

[0017] Currently, woven towels, whether woven before dyeing or dyed before weaving, have the same warp feed and tension for each warp yarn during the weaving process. Therefore, woven towels on the market can only be made with one side being plain pile (without loops) and the other side being plain fabric (without loops); or both sides being loops. It is not possible to produce single-sided towels with one side being plain fabric (without loops) and the other side having a loop pattern (i.e., having both plain fabric and loops, and the height of the loops can be varied at will). Summary of the Invention

[0018] To address the shortcomings of existing technologies, this invention provides a single-sided jacquard towel and its weaving process. The reverse side of the resulting single-sided jacquard towel is plain fabric, while the front side has a floral pattern. That is, the front side has both plain fabric and loops, and the height of the loops can be varied at will.

[0019] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0020] A woven process for a single-sided jacquard towel includes: warping, sizing the ground warp beam, hanging the yarn on the pile warp bobs, weaving, post-treatment, and finishing.

[0021] The warping process only involves warping the ground warp axis;

[0022] The single-sided jacquard towel is made of pure cotton with a thread count of (10-15). S / 5, twist is 10-15 twists / 10cm; the ground material is pure cotton, and the count is (20-23). S / 2, twist is 50-52 twists / 10cm; weft yarn is pure cotton, count is (10-15). S / 4, twist is 10-15 twists / 10cm; warp density is 55-65 threads / 10cm; ground warp density is 100-140 threads / 10cm; weft density is 30-35 threads / 2.54cm;

[0023] The warping process involves hanging 500-1200 yarn bobbins on a warping frame, operating at a speed of 500-700 r / min, with a winding tension of 25-35 N, pulling the yarn onto a square spool, and winding it into a spool to obtain a square spool with the yarn wound.

[0024] The ground warp sizing process involves placing a square spool of yarn on the sizing frame of a sizing machine, then passing the yarn through a sizing trough and an oven before winding it onto the ground warp to obtain a sized ground warp.

[0025] In the ground warp sizing, the solid content of the sizing liquid in the sizing tank is 2-2.5%, and the solid components in the sizing liquid are composed of corn starch, modified starch, and wax flakes, wherein the mass ratio of corn starch, modified starch, and wax flakes is 8-12:8-12:2-4.

[0026] The temperature of the oven is 130-150℃;

[0027] The speed of the sizing machine is 80-120 m / min;

[0028] The weaving process involves placing the warp yarn bobbins on the yarn rack behind the loom, passing the warp yarns through independently controllable small rollers, each of which independently provides the required warp feed during the weaving process. After being actively fed by the small rollers, the yarns enter the same set of large rollers, connecting each warp yarn with the warp yarns on the loom. The sized ground warp beam is fixed on the warp beam frame of the towel loom, and the yarns on the ground warp beam are connected with the ground warp yarns on the loom to weave the towel fabric.

[0029] In the weaving process, the loop height of the towel fabric is 0-1cm, corresponding to a small roller speed of 32-150cm / min and a tension of 100-400CN; the flat fabric corresponds to a small roller speed of 32cm / min and a tension of 400CN.

[0030] The loom speed is 300-350 r / min, and the ground warp tension is 1800-2200 N;

[0031] The post-processing includes: boiling, dyeing, soaping, softening, and drying;

[0032] The scouring and bleaching process involves immersing the raw fabric in the scouring and bleaching solution and circulating it for 45-55 minutes at a temperature of 93-97℃.

[0033] The mass-to-volume ratio of the greige fabric to the scouring and bleaching liquor is 500-600 kg: 5500-6500 L;

[0034] The bleaching solution is composed of water, caustic soda, hydrogen peroxide stabilizer, and hydrogen peroxide, wherein the concentration of caustic soda is 4-6 mL / L, the concentration of 27.5% hydrogen peroxide is 9-11 mL / L, and the concentration of hydrogen peroxide stabilizer is 0.15-0.25 mL / L.

[0035] The boiling and rinsing process is carried out in an overflow machine;

[0036] The dyeing process involves placing the bleached and boiled fabric in a dye bath and circulating it at 55-65℃ for 25-35 minutes.

[0037] The dyeing is performed in an overflow machine;

[0038] The concentration of Remazol Red 3B in the dye bath is 4-6 g / L, the concentration of sodium sulfate is 7-9 g / L, and the concentration of soda ash is 4-6 g / L.

[0039] The soaping process involves circulating a detergent solution at 87-93°C for 13-17 minutes.

[0040] The concentration of the cleaning agent solution is 0.12-0.18 g / L;

[0041] The softening process involves adding the softener to the mixture and cycling it at 38-42°C for 28-32 minutes.

[0042] The softener is softener JWJ with a concentration of 3 g / L;

[0043] The manufacturer of the fabric softener JWJ is Clariant.

[0044] The drying process is carried out using a flat-width loose-type dryer.

[0045] The finishing process includes sewing, inspection, and packaging.

[0046] A single-sided jacquard towel made using the aforementioned weaving process.

[0047] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0048] (1) The weaving process of the single-sided jacquard towel of the present invention can weave a single-sided jacquard towel with a plain cloth on the reverse side and an arbitrary loop pattern on the front side on a regular multi-arm loom. The weight of the single-sided jacquard towel is 300-700gsm and the loop height can be adjusted between 0-1cm, which greatly enriches the variety of towel patterns.

[0049] (2) The single-sided jacquard towel of the present invention is woven by directly weaving yarn bobbins instead of using a yarn warp beam. Attached Figure Description

[0050] Figure 1 The image shows a comparison between a single-sided jacquard towel obtained in Example 1, a towel with a flat pile on the front and a flat cloth on the back, and a towel with loops on both sides.

[0051] The left image shows a towel with a flat pile on one side and a flat cloth on the other; the middle image shows a towel with loops on both sides; and the right image shows a single-sided jacquard towel. Detailed Implementation

[0052] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention are now described.

[0053] Example 1

[0054] A single-sided jacquard towel weaving process includes: warping (warping only the ground warp beam) - sizing the ground warp beam - hanging the yarn on the wool warp bobbin - weaving - post-treatment - finishing (sewing, inspection and packaging).

[0055] The specifications of the single-sided jacquard towel are as follows:

[0056] 1. Wool warp: Pure cotton, 12 S 5. Twist: 12 twists / 10cm

[0057] Earth's properties: pure cotton, 21 S 2. Twist: 51 twists / 10cm

[0058] Weft yarn: pure cotton, 12 S 4. Twist: 12 twists / 10cm

[0059] “S” indicates British Central Bank

[0060] 2. (Wool) Warp density: 60 threads / 10cm

[0061] (Ground) Density: 120 roots / 10cm

[0062] 3. Weft density: 32 threads / 2.54cm

[0063] 4. Terry cloth height: 0.6cm

[0064] 5. Specifications: 100cm × 100cm

[0065] 6. Weight: 500 grams

[0066] A woven fabric process for a single-sided jacquard towel, specifically:

[0067] 1. Warping (warping only the ground warp beam): According to the warping process, hang 500 yarn bobbins on the warping frame, with a machine speed of 600 r / min and a winding tension of 30 N. Pull the yarn onto the square spool and wind it into a spool to obtain a square spool with the yarn wound.

[0068] 2. Sizing the ground warp beam: Place the square spool of yarn on the sizing frame of the sizing machine, and then wind the yarn through the sizing tank and the drying oven onto the ground warp beam to obtain the sized ground warp beam;

[0069] The sizing solution in the sizing tank has a solid content of 2.3%, and its solid components consist of corn starch, modified starch, and wax flakes, with a mass ratio of 10:10:3. The oven temperature is 140℃, and the sizing machine speed is 100m / min. After the sizing process, the yarn's strength and abrasion resistance are significantly improved, making it suitable for weaving on a loom.

[0070] 3. Weaving: First, place each warp yarn bobbin on the yarn rack at the back of the loom. Then, pass the yarn through the independently controllable small rollers. Each small roller independently provides the required amount of warp feed during the weaving process. After being actively fed by the small rollers, the yarn enters the same set of large rollers. The large rollers hold the warp yarns to prevent the yarn from turning back at the small rollers.

[0071] Then each warp yarn is joined to the warp yarn on the loom; the height of the loop is 0.6cm, corresponding to a small roller speed of 90cm / min and a tension of 200CN; the small roller speed for the flat fabric is 32cm / min, and the tension is 400CN.

[0072] The sized ground warp beam is then fixed onto the warp beam frame of the towel loom, and the yarns on the ground warp beam are joined with the ground warp yarns on the loom. The towel fabric is then woven according to the requirements of the weaving process. The loom speed is 360 r / min, and the ground warp tension is 2000 N.

[0073] 4. Post-processing: The raw towel fabric from the loom undergoes boiling, bleaching, dyeing, soaping, softening, and drying to obtain post-processed towels. Post-processing gives the towels a usable feel, absorbency, and appearance. Specifically:

[0074] (1) Boiling and bleaching: 550 kg of greige fabric is placed into 6000 L of boiling and bleaching solution made of water, caustic soda, hydrogen peroxide stabilizer and hydrogen peroxide using an overflow machine. The concentration of caustic soda in the boiling and bleaching solution is 5 mL / L, 27.5% hydrogen peroxide is 10 mL / L and hydrogen peroxide stabilizer is 0.2 mL / L. The solution is circulated for 50 min at a temperature of 95℃.

[0075] (2) Dyeing: The dyeing process is carried out in an overflow machine. The concentration of Remazol Red 3B in the dye bath is 5 g / L, the concentration of sodium sulfate is 8 g / L, and the concentration of soda ash is 5 g / L. The fabric is dyed by circulating the dye bath at 60°C for 30 minutes.

[0076] (3) Soap boiling: Circulate a detergent solution with a concentration of 0.15 g / L at 90°C for 15 min to remove unfixed dyes and chemicals from the fabric;

[0077] (4) Softening: Add 3g / L of softener JWJ, and then circulate at 40℃ for 30min;

[0078] The softener JWJ is manufactured by Clariant, and its function is to make fabrics softer and fluffier after treatment.

[0079] (5) Drying: A flat-width loose dryer is used to dry the product, making it fluffier and softer to the touch;

[0080] 5. Finishing (sewing, inspection and packaging): The towels have been finished and are now usable. They are then sewn together to seal the four sides, and after inspection, they are packed into boxes.

[0081] This embodiment also provides a single-sided jacquard towel made by the aforementioned weaving process.

[0082] The single-sided jacquard towel obtained in this embodiment is compared with a towel with a plain pile front and a plain fabric back, and a towel with loops on both sides. See the comparison diagram below. Figure 1 As shown, Figure 1 The left image shows a towel with a napped front and a flat back; the middle image shows a towel with loops on both sides; and the right image shows a single-sided jacquard towel. Figure 1 As can be seen, the reverse side of the single-sided jacquard towel obtained in this embodiment is a flat fabric, while the front side has a floral pattern. This means that the front side has both a flat fabric and loops, and the height of the loops can be changed at will by adjusting the amount and tension of the warp yarns.

[0083] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
