Description

Technical Field

[0001] The invention relates to the field of textiles, and in particular to a manufacturing process of a paper webbing tape. Background Art

[0002] Woven labels are cloth labels woven on clothes and trousers, containing words, letters, and logo patterns. They are used by clothing factories, garment factories, and home textile factories in their production, manufacturing, processing, or sales of clothing and home textiles to distinguish the sources of clothing and home textiles. They are marked with distinctive features, including words, graphics, letters, numbers, three-dimensional signs, color combinations, or a combination of the above elements, and are the product of the modern economy.

[0003] However, in the prior art woven label preparation process, the woven label is generally obtained by melt-cutting the four sides of the woven label. This technology is complex, difficult to weave, low in yield, easy to skew, difficult to post-finish, and the woven label obtained by melt-cutting the four sides often has lumps, which makes the skin feel poor when worn. Natural fibers cannot achieve this and the cut edges will fall apart. Summary of the invention

[0004] The technical purpose of the present invention is to solve the problems in the background technology and provide a manufacturing process of a paper webbing tape.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A manufacturing process of a paper woven edge tape, wherein the woven edge tape is woven by double shuttle weaving of warp yarn and weft yarn; the weft yarn serves as the surface of the woven edge tape, and the warp yarn has three layers.

[0006] The three layers of warp yarns are, from top to bottom, the surface warp yarn, the middle warp yarn, and the bottom warp yarn.

[0007] Preferably, the face weft yarns and bottom weft yarns of the paper woven edge band are layered wool blended skin-friendly layers, the warp yarns include skin-friendly and antibacterial face warp yarns, middle warp yarns formed by polyester spinning, and sisal bottom warp yarns, and the wool blended skin-friendly layer in the weft yarns uses wool and bio-based nylon blended yarns.

[0008] Preferably, the wool-blended skin-friendly layer in the weft yarn is made of wool and bio-based nylon blended yarn by the following blending process steps: Step S1: preparing an antibacterial colorant: using ethylene-methyl acrylate-glycidyl methacrylate terpolymer EMA as a compatibilizer and polypentamethyleneguanidine sulfate PPGS as an antibacterial agent to prepare an antibacterial colorant improved by a compatibilizer; Step S2: Antibacterial treatment of bio-based nylon PA56: bio-based nylon PA56, a compatibilizer EMA, and an antibacterial agent PPGS are added to an extruder in proportion to obtain a blended slice, and then the blended slice is dried in a vacuum drum dryer at 95° C.-110° C., and finally melt-spun and stretched to obtain bio-based nylon PA56 fiber yarn after antibacterial treatment; Step S3: blending of wool and bio-based nylon yarn: the bio-based nylon PA56 fiber obtained in the above step S2 and wool are subjected to a carding machine, a drawing machine, a roving machine and a spinning tester according to a specific blending ratio to prepare the blended yarn.

[0009] Preferably, in the antibacterial treatment of bio-based nylon PA56 in step S2, the mass fraction of the compatibilizer EMA is 0.5-10 parts, the mass fraction of the antibacterial agent PPGS is 0.5-10 parts, and the rest is bio-based nylon PA56, and the total mass fraction of the compatibilizer, antibacterial agent and bio-based nylon PA56 is 100 parts.

[0010] Preferably, the obtained slices are dried in a vacuum drum dryer at 105° C. to reduce the moisture content to 375-420 ppm.

[0011] Preferably, after the above steps are completed, the obtained antibacterial PA56 slices are melt-spun through a spinning machine spinneret at a winding speed of 4000-4500 m / min and a spinning temperature of 250°C-300°C, and stretched to obtain the antibacterial treated bio-based nylon PA56.

[0012] Preferably, in the blending process of wool and bio-based nylon yarn in step S3, the wool content in the blended yarn is 10-80%.

[0013] The advantage of the present invention is that bio-based nylon PA56 is treated with antibacterial agents by using a compatibilizer and an antibacterial agent to prepare a bio-based PA fiber with good antibacterial properties. The process improves the compatibility of PA56 and the antibacterial agent through a membrane opening reaction, alleviates the disadvantages caused by excessive dissolution of the antibacterial agent, and improves the mechanical properties of the fiber and the subsequent dyed finished yarn.

[0014] The advantage of adopting the present invention is that bio-based nylon (PA56) not only has the same physical properties as nylon (PA6 / PA66), but also its production method is more environmentally friendly. PA56 fabric has the advantages of moisture absorption, perspiration, high temperature resistance, flexibility, etc., and has been widely studied by scientific researchers; wool has the advantages of beauty, environmental protection, and wrinkle resistance.

[0015] Pure wool fabrics have low strength and are easy to shrink after washing, which has always been a problem. The invention has the advantage of blending wool with bio-based nylon yarn at the most suitable wool content, which can not only improve the gloss, elasticity, feel and comfort of the blended fabric, but also make up for the insufficient strength of wool, and can achieve the technical effects of saving resources, biodegradability and environmental friendliness, and has a wide application prospect in the textile field.

[0016] Preferably, the skin-friendly and antibacterial surface warp yarn in the warp yarn is made by mixing antibacterial wool yarn fibers with pretreated wool yarn fibers, and the preparation process is as follows: Step (1) wool fiber pretreatment: the wool fiber is pretreated by impregnation with tri(3-hydroxypropyl)phosphine pretreatment solution and then sent to subsequent antibacterial wool fiber processing and preparation; Step (2) Preparation of antibacterial wool fiber: the wool pretreated in step (1) is immersed in an antibacterial treatment solution for 5 minutes to obtain antibacterial wool; Step (3) blending the antibacterial wool yarn with the wool yarn fiber: blending the pretreated wool fiber obtained in step (1) with the antibacterial wool fiber obtained in step (2) in a ratio of (1-4):1 to obtain the skin-friendly and antibacterial surface warp yarn.

[0017] Preferably, in step (1), the pretreatment solution comprises 50-180 g / L tri(3-hydroxypropyl)phosphine, 10-30 g / L penetrant, 10-20 g / L polyethylene glycol and 100-500 g / L urea; the pH of the pretreatment solution is adjusted to between 3 and 9, and the wool fiber is placed in the pretreatment solution at a bath ratio of 60:1, soaked at 30-90°C for 1-24 hours and then dried at 25-40°C to obtain the pretreated wool fiber that is convenient for subsequent processing and dyeing.

[0018] The invention has the advantage of adopting a novel keratin fiber pretreatment method, utilizing the swelling effect of urea at room temperature to allow tri(3-hydroxypropyl)phosphine, a highly efficient reducing agent, to penetrate into the fiber molecules in advance, and utilizing the wrapping effect of small molecule polyethylene glycol to protect its reducing property, so that when the pretreated keratin fiber is subsequently processed, the tri(3-hydroxypropyl)phosphine stored inside can be utilized to quickly destroy the disulfide bonds in the fiber when the temperature is raised, thereby greatly improving the dyeing and finishing processing and dissolution efficiency thereof. Although the invention does not involve too many dyeing and finishing procedures, the addition of this method is also of great significance for wool textiles with dyeing requirements.

[0019] Preferably, in step (2), the antibacterial treatment solution is prepared by mixing 20-30 parts of Pittosporum tobira leaf extract, 30-50 parts of Dianthus chinensis flower extract, 15-25 parts of antibacterial enhancer and 15-20 parts of softener; the pretreated wool fiber is immersed for 5 minutes, dried at 30°C and then naturally air-dried at room temperature for 1-5 days to obtain antibacterial wool fiber.

[0020] Preferably, the antibacterial enhancer is citral.

[0021] The invention has the advantages of using the Pittosporum leaf extract and the Dianthus flower extract as the main natural raw materials, the Pittosporum leaf extract and the Dianthus flower extract have good antibacterial and antifungal effects, the antibacterial enhancer further improves the antibacterial effect of the finishing agent, and effectively improves the antibacterial and antifungal effects of wool.

[0022] The invention has the advantage that citral can inhibit bacterial survival and destroy bacterial activity, further shorten the bacterial death time, and further improve the antibacterial property of wool.

[0023] Preferably, the specific structure of the webbing band is: weft yarns exposed on the surface, skin-friendly and antibacterial surface warp yarns, middle warp yarns and bottom warp yarns, wherein the middle warp yarns and bottom warp yarns are both prepared by polyester spinning, and the skin-friendly and antibacterial surface warp yarns are the side close to human skin.

[0024] Preferably, one warp yarn is woven on the weft yarn after every n (3≤n≤6) warp yarns in the surface warp yarns and the bottom warp yarns; and the number of yarns in each layer of the three-layer warp yarns differs by no more than 2, thereby forming the structure of the webbing band.

[0025] The advantage of adopting the present invention is that through the above-mentioned yarn layer structure, the effect of having the weft yarn as the surface and the warp yarn not being exposed can be formed, so that when the product of the present invention is produced as a woven label, a long strip structure of the edge band is caused, and there is no need to melt-cut the four sides. Only the two narrow sides of the edge band sewn to the clothing need to be cut, and these two sides will not contact the human skin; the surface in contact with the human skin and the two long sides are all made of skin-friendly materials, and there is no melting and cutting process, which improves the problems existing in the prior art from two aspects.

[0026] The invention has the advantages that the prepared woven edge tape has excellent antibacterial dyeing processing performance, low weaving difficulty and high output, and is applied to the woven label to eliminate four-side melting, reduce loose edges in wearing, improve skin-friendliness and provide good physical feel.

[0027] In summary, the present invention has the following beneficial effects: 1. Through the special yarn layer design of the warp and weft yarns of the present invention, the skin-friendly weft yarn layer can be used as the surface, thereby improving the comfort of the clothes on people; 2. Through the special yarn layer design of the warp and weft yarns of the present invention, the woven label does not need to be melt-cut on four sides when cutting, but only needs to cut two narrow sides, and these two narrow sides are directly sewn on the clothes without contacting the human skin, which also improves the comfort and skin-friendliness of use; 3. The wool and bio-based nylon blended yarn in the wool blended skin-friendly layer in the weft yarn prepared by the blending process in this scheme is first treated with an antibacterial agent and an antibacterial agent for the bio-based nylon PA56, and then the wool and bio-based nylon yarn are blended with the most suitable wool content, which can not only improve the gloss, elasticity, feel and comfort of the blended fabric, but also make up for the insufficient strength of the wool, and can achieve the technical effects of saving resources, biodegradability and environmental friendliness, and has a wide range of application prospects in the textile field; 4. Through a new type of keratin fiber pretreatment method in this scheme, combined with an antibacterial treatment liquid, the antibacterial effect of the finishing agent is further improved, the antibacterial and antifungal effect of wool is effectively improved, and the antibacterial performance of wool is further improved; 5. The prepared woven edge tape has excellent antibacterial dyeing processing performance, low weaving difficulty and high output. It is used in woven labels to eliminate four-side melting and reduce loose edges, improve skin-friendliness and provide good body feel when worn. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] The preparation process of skin-friendly weft yarn is as follows: Step S1: preparing an antibacterial colorant: using ethylene-methyl acrylate-glycidyl methacrylate terpolymer EMA as a compatibilizer and polypentamethyleneguanidine sulfate PPGS as an antibacterial agent to prepare an antibacterial colorant improved by a compatibilizer; Step S2: Antibacterial treatment of bio-based nylon PA56: 90 parts of bio-based nylon PA56, 5 parts of compatibilizer EMA, and 5 parts of antibacterial agent PPGS are added to an extruder in proportion to obtain a blended slice, and then the blended slice is dried in a vacuum drum dryer at 105°C to reduce the moisture content to 410ppm; after the above steps are completed, the obtained antibacterial PA56 slice is melt-spun through a spinning machine spinneret at a winding speed of 4500m / min and a spinning temperature of 290°C, and stretched and deformed to obtain the bio-based nylon PA56 after antibacterial treatment; Step S3: blending of wool and bio-based nylon yarn: the bio-based nylon PA56 fiber prepared in the above step S2 and wool are processed through a carding machine, a drawing frame, a roving frame and a spinning tester to prepare the blended yarn, wherein the wool content in the blended yarn is 65%.

[0066] Comparative Example 1

[0067] Different from the above-mentioned embodiment, the warp yarns in this comparative example are all made of polyester spinning, and the weft yarns are prepared in the same manner as in Example 4: The preparation process of skin-friendly weft yarn is as follows: Step S1: preparing an antibacterial colorant: using ethylene-methyl acrylate-glycidyl methacrylate terpolymer EMA as a compatibilizer and polypentamethyleneguanidine sulfate PPGS as an antibacterial agent to prepare an antibacterial colorant improved by a compatibilizer; Step S2: Antibacterial treatment of bio-based nylon PA56: 90 parts of bio-based nylon PA56, 6 parts of compatibilizer EMA, and 4 parts of antibacterial agent PPGS are added to an extruder in proportion to obtain blended slices, and then the blended slices are dried in a vacuum drum dryer at 105°C to reduce the moisture content to 400ppm; after the above steps are completed, the obtained antibacterial PA56 slices are melt-spun through a spinning machine spinneret at a winding speed of 4250m / min and a spinning temperature of 275°C, and stretched and deformed to obtain bio-based nylon PA56 after antibacterial treatment; Step S3: blending of wool and bio-based nylon yarn: the bio-based nylon PA56 fiber prepared in the above step S2 and wool are processed through a carding machine, a drawing frame, a roving frame and a spinning tester to prepare the blended yarn, wherein the wool content in the blended yarn is 35%.

[0068] And the yarn layer structure is consistent with that of Example 4.

[0069] Comparative Example 2

[0070] Different from the above comparative example 1, the weft yarn in this comparative example is made of polyester spinning, and the warp yarn is prepared by the same preparation process as that of Example 4, and the yarn layer structure is consistent.

[0071] Comparative Example 3

[0072] Different from the above comparative example, the warp and weft yarns of this comparative example are both made of polyester spun yarn, but the yarn layer structure is consistent with that of Example 4.

[0073] Comparative Example 4

[0074] There is no special preparation design for the warp and weft yarns, and the yarn layer structure is the common warp yarn on the market, and the product woven label is melt-cut on the four sides.

[0075] The above embodiments and comparative examples are tested for their edge frayability, surface skin-friendliness, dry friction and wet friction experimental tests, and whether their tensile mechanical properties are good or poor.

[0076] The method to detect whether it is easy to scatter is to melt or cut the two narrow sides of the product and observe the scattering of the edge yarn.

[0077] The evaluation standard for the skin-friendliness of the surface is to melt-cut the two sides of the webbing tape prepared by the scheme of the present invention into a woven label and sew it to the clothing, invite 50 testers to wear the clothing to feel the skin-friendliness and comfort of the woven label, and make an evaluation on it, and record it with the praise rate.

[0078] The evaluation standard of Lala's mechanical properties is whether the woven label will break or be damaged when torn by strong human force. Since it only needs to be used as a clothing trademark woven label, the mechanical performance requirements are not high.

[0079] The dry friction and wet friction test methods refer to GB / T 3920-2008, and the dry and wet friction color fastness rating is 1-5, with 1 being the worst and 5 being the best.

[0080] The test results of the embodiment are shown in Table 1 below: Table 1 Example test results

[0081] The test results of the comparative example are shown in Table 2 below: Table 2 Comparative Example Test Results

[0082] From the above two tables we can conclude that: The woven label prepared by the webbing tape obtained in Example 4 has the best skin-friendliness and good tensile strength, and the two sides are not loose after being melt-cut; in the dry and wet friction test, the color fastness can reach level 5; at the same time, it can better achieve the maximum benefit, reduce the high-cost wool in the use direction, and maximize the improvement of skin-friendliness and overcome the shortcomings of wool fiber itself; It can be concluded from Examples 1-2 that the woven labels of the webbing bands prepared under the conditions of the limited range end values, although their performance is better than that of ordinary woven labels, cannot be compared with the products prepared under the conditions of Example 4, and their color fastness is also inferior to the samples of Examples 4-6; Although the performance of the woven edge tape products obtained in Examples 3 and 5-6 is good, it is still not as good as the woven edge tape of Example 4.

[0083] It can be concluded from the results of Examples 1-4 that the warp and weft yarn composition and the weft double shuttle yarn layer structure design in the scheme of the present invention play a significant role in producing woven labels with good skin-friendly, color fastness, stretchability and other properties.
