Description

Technical Field

[0001] The present invention relates to the technical field of clothing, and in particular to a worsted spinning method, equipment and clothing for manufacturing staple tencel blended yarns. Background Art

[0002] Zero-carbon tencel fiber is derived from natural renewable wood sources. By adopting more efficient production methods, renewable energy and new technologies are used to continuously reduce carbon emissions. Zero-carbon emissions are achieved through emission reduction, participation and offset, so it is called "zero-carbon tencel". Currently, the length of zero-carbon tencel fiber is usually 38mm, which is suitable for production by cotton spinning equipment. Therefore, existing zero-carbon tencel products are all produced by cotton spinning processes. Due to the too short fiber length, it is impossible to produce related products on worsted spinning equipment.

[0003] Since zero-carbon tencel has characteristics such as skin affinity, good drape, and lower static electricity risk, the fabric blended with zero-carbon tencel and wool can reduce static electricity, have higher quality, be more delicate, and have a softer handfeel. However, wool fibers are naturally curly and are not parallel and straight like cotton and chemical fibers. They need to be combed through needle plates. The cotton spinning process does not have various gilling processes, and the wool fibers are too long, exceeding the suitable fiber length of cotton spinning equipment. The effective output length of a cotton spinning comber is 30 - 40mm, which is much lower than the wool fiber length, resulting in problems such as fiber breakage and wool winding. Therefore, we considered whether it is possible to achieve the blending process of wool and zero-carbon tencel in worsted spinning equipment. However, due to the too short length of the zero-carbon tencel fiber used for blending, it is not suitable for worsted spinning equipment that has requirements for the raw material length, which will affect the cohesion between fibers and prevent strip formation. At the same time, problems such as wool winding, large chunks of raw materials that cannot be combed out, and a significant increase in falling wool will occur during production, resulting in smooth production being impossible. Therefore, if zero-carbon tencel fiber and wool fiber are used as raw materials for worsted spinning processing, problems such as difficulty in strip formation, easy wool winding, and inability to comb out will occur.

[0004] Therefore, after our final consideration, we decided to first make strips of staple tencel such as zero-carbon tencel fiber and wool fiber respectively, and then process the made staple tencel strips and wool strips in the improved worsted spinning equipment, so as to successfully produce wool / zero-carbon tencel blended yarns, weave high-grade fabrics with a dry handfeel, moisture absorption and breathability, and use them to manufacture clothing that conforms to the clothing brand concept and the green concept of consumers, while making contributions to energy conservation, emission reduction and ecological protection.

The flat plates in the sliver blending zone, the first gill zone, the second gill zone, and the third gill zone are No. 9 flat plates. The roller gauge of the flat plates in the sliver blending zone, the first gill zone, the second gill zone, and the third gill zone are set to 35, 35, 32, and 30 respectively.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The blended worsted spinning of zero-carbon tencel and wool in the present invention realizes the functions of energy conservation, emission reduction and ecological protection, and obtains fabrics with higher quality, finer texture and softer handfeel, while reducing static electricity.

[0042] (2) The worsted spinning method and equipment effectively solve the technical problem that short-fiber tencel and its blended fibers cannot be worsted spun on worsted spinning equipment. At the same time, it solves the problems such as easy fiber breakage, easy hair winding, unrefined and low-end products caused by the mixing of zero-carbon tencel fibers and wool fibers. It also effectively solves the problems such as difficult sliver formation, easy hair winding and inability to comb out after the mixing of zero-carbon tencel fibers and wool fibers, making the blended fiber sliver have good evenness, good strength and not easy to break.

[0043] (3) The card clothing cleaning module and height detection module in the worsted spinning equipment of the present invention timely detect the fiber condition deposited in the card clothing needle gaps, reduce the occurrence of wool particles during the sliver making process of zero-carbon tencel, and enable the subsequent blended worsted spinning to proceed smoothly; the needle tip detection module timely detects the state of the card clothing needle tips, reduces the occurrence of wool particles during the sliver making process of zero-carbon tencel, and enables the subsequent blended worsted spinning to proceed smoothly.

[0044] (4) Since zero-carbon tencel is prone to fibrillate, wool particles may be generated due to fibrillization after multiple gilling processes. Therefore, after designing multiple gilling processes in the gilling module of the worsted spinning method of the present invention, a combing module is also designed for combing to remove impurities, and then parallel straightening and loosening are carried out to create good conditions for spinning.

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention. The term "including" and its variants used herein mean open inclusion, that is, "including but not limited to", and there may also be other explicit and implicit definitions hereinafter. In the following embodiments, if there is no special description of functional components or structures, it means that they are all conventional components or conventional structures adopted in the art to achieve the corresponding functions. Since all current zero-carbon tencel are short-fiber tencel, the following takes zero-carbon tencel as an example to describe short-fiber tencel in detail.

[0048] As Figure 1 and 2 shown, Embodiment 1 of the present invention provides a worsted spinning method for manufacturing short-fiber tencel blended yarns, including the following steps:

[0049] S1. Ribbon-making process:

[0050] Respectively make wool fibers and tencel fibers into wool ribbons and tencel ribbons;

[0051] S2. Double combing process:

[0052] Mix and card the wool ribbon and tencel ribbon obtained in step S1, and comb out impurities by combing. After removing impurities, mix and card again, and draw and card multiple times to form a wool ball;

[0053] S3. Spinning process:

[0054] Mix and card the wool ball obtained in step S2, draw, and twist at the same time to obtain a sliver, twist the sliver into fine yarn, and then perform steaming treatment to obtain short-fiber tencel blended yarns.

[0055] In this embodiment, in the ribbon-making process of step S1, the specific steps of making wool fibers into wool ribbons are as follows: First, detect the wool fibers to obtain relevant data including wool oil content, moisture regain of wool raw materials, target moisture regain, environmental humidity, environmental temperature, average length and fineness of wool, etc., perform distribution or configuration of data including oil addition amount, antistatic agent addition amount, water addition amount, etc., add oil, add antistatic agent, add water, and then perform gilling and carding to produce wool ribbons;

[0056] The addition amounts of oil, water, and antistatic agent can refer to Table 1:

[0057] Table 1

[0058]

[0059] Exemplarily, in this embodiment, the proportion of wool top is 65%, the zero-carbon tencel top is used for the tencel top, and the proportion of the zero-carbon tencel top is 35%. The addition amounts of oil and antistatic agent are determined according to the oil content of the wool top, the addition amount of water is determined according to the moisture regain of the wool raw material, the target moisture regain, and the environmental humidity, and the addition amount of antistatic agent is determined according to the proportions of wool and other fibers. In this embodiment, the target moisture regain of the wool top is 18%-19%, the target oil content is 0.9%-1.0%, and the addition amount of antistatic agent is 0.3%-0.6%.

[0060] In this embodiment, in the top-making process of step S1, the specific steps of making the tencel fibers into tencel tops are as follows: the zero-carbon tencel fibers are opened into fluffy bundles by a carding machine, and then the bundled zero-carbon tencel fibers are further decomposed into single fibers by a comber and can be initially straightened and parallelized. However, due to the fibrillation characteristics of zero-carbon tencel, it is necessary to control the temperature and humidity, especially the relative humidity, and maintain the lowest moisture content under the condition of ensuring the control of static electricity. Since the zero-carbon tencel fibers are short, during carding, the gauge between the working roller and the doffer and the cylinder in the comber should be less than the length of the zero-carbon tencel fibers. During carding, the needles of the comber are pre-detected by pulse or detected by setting a detection time period to collect needle data. When the comber is working, the height detection module real-time detects the fiber height deposited in the needle gaps of the cylinder card clothing. When it exceeds the threshold, the comber stops the carding action, and the cylinder card clothing cleaning module cleans the needle gaps of the cylinder card clothing; the needle detection module real-time detects the needle state of the cylinder card clothing. If phenomena such as missing needles, bent needles, broken needles, or incorrect needle angles are detected, the comber stops the carding action for correction. The drawframe drafts and collects the zero-carbon tencel fibers carded by the comber into zero-carbon tencel tops, and the roller distance in the drawframe is less than the length of a single tencel fiber.

[0061] In this embodiment, in the double-combing process of step S2, the wool top and the zero-carbon tencel top are fully mixed by a gilling machine GN6 or VSN to play the role of drafting and carding the mixed top and controlling the top weight, for a total of 5 gillings; the short fibers, weeds, wool grains and other impurities that do not meet the process requirements are removed by a comber ALFA, for 1 combing; then the wool top and the zero-carbon tencel top are mixed evenly by a gilling machine VSN or ST21 to make the fibers straight and parallel, with even sliver, tight cohesion, reduce the unevenness rate, and draft and card the combed top into a wool ball to control the top weight, for a total of 2 gillings, completing the double-combing process. Therefore, in this double-combing process, the wool top and the zero-carbon tencel top are mixed and carded 8 times.

[0062] Table 2 shows the double-combing effects at different mixing and carding times:

[0063] Table 2

[0064]

[0065] In this embodiment, in the spinning process of step S3, drawing, first drawing, second drawing, third drawing, and fourth drawing are carried out by a cashmere screw type VSN gilling machine; the flat plates of the drawing to the third drawing adopt the 9# flat plate with the densest needles. The 9# flat plate is used because the fineness of Tencel is very fine, only 11μm, which is finer than 130s wool (known as golden wool with a fineness of 13.5μm). Therefore, the 9# flat plate is used for full carding. If a sparse flat plate is used, it will not play a great carding role. The speed of the gilling machine is set at 60 - 70m / min. If the speed is too fast, the phenomenon that the zero-carbon Tencel is not fully carded will occur. Table 3 shows the comparison of carding effects at different speeds.

[0066] Table 3

[0067] Vehicle speed (m / min) Presentation of carding effect 60-70 The sliver web is clear and no tencel fibers are found to be uncarded 70-90 Occasionally, tencel fibers are found to be uncarded 90-100 Small bundles of tencel fibers are found to be uncarded and will wrap around the sliver

[0068] Since the fiber length of the zero-carbon Tencel combed sliver is short, in order to produce smoothly, the roller gauge needs to be set smaller. Therefore, in this embodiment, the roller gauges of drawing, first drawing, second drawing, and third drawing are set at 35, 35, 32, and 30 respectively. By adjusting the weight of the fed sliver and the draft multiple, the raw materials are fully mixed and carded, combined and drafted, and the sliver weight is reduced, so that the fibers are straightened and parallel, the sliver evenness is good, the cohesion is tight, the unevenness rate is reduced, and at the same time, fine impurities and short fibers are removed. After testing, the metric length of the zero-carbon Tencel fiber after being processed into sliver is 31.8mm, and the Babu length is 35mm. Table 4 shows the carding effects at different roller gauges.

[0069] Table 4

[0070]

[0071] Immediately afterwards, the fourth drawing further drafts and combs the sliver from the third drawing to reduce the sliver weight. In this roving process, the sliver is drafted into a sliver that can be used on a ring spinning frame, and at the same time, it is twisted to make the roving have a certain tightness and strength, so that the subsequent winding into a yarn bobbin is convenient for storage, handling, and feeding into the ring spinning frame. By using the compact spinning technology on the ring spinning frame, the hairiness is reduced, the cohesion between yarns is increased, and the yarn strength is improved. In this embodiment, after the ring spinning is completed, steaming treatment at 60°C is also carried out. Steaming can eliminate most of the yarn tension. If it is ply yarn, after the winding process, doubling, twisting are carried out, and after the twisting is completed, steaming and shaping at 60°C are required again to obtain the final finished worsted yarn.

[0072] In this embodiment, the worsted yarn prepared in step S3 is subjected to package dyeing. Package dyeing has the advantages of smooth yarn surface, less hairiness, and good pilling resistance, which can improve the yarn fineness. Both single yarn and ply yarn can be subjected to package dyeing, and the yarn for circular knitting machine can be subjected to grey fabric dyeing.

[0073] The equipment used for cheese dyeing is an Italian OBEM dyeing machine, and the specific steps are as follows:

[0074] a. Loose cheese: Use a perforated plastic bobbin, and wind the cheese yarn into a cheese with a density of about 382 kg / m 3 on a winding machine.

[0075] b. Pretreatment: Treat with a pretreatment agent at 70 °C for 10 minutes.

[0076] c. Dyeing: Add the required dyes, sodium sulfate, soap detergent, soda ash, sodium acetate, etc. to the dyeing vat for dyeing. The dyeing temperature is 98 °C, and the total dyeing time is 90 minutes.

[0077] d. Wash off the floating color with a detergent. The process temperature is 90 °C and the time is 20 minutes.

[0078] The performance tests of wool / zero-carbon tencel blended yarns with different specifications are shown in Table 5:

[0079] Table 5

[0080]

[0081] As can be seen from Table 5, the wool / zero-carbon tencel blended yarns prepared by this embodiment have high strength.

[0082] Finally, the dyed yarn is made into finished clothes.

[0083] In one embodiment, the mixing and carding further includes the following steps:

[0084] Preset a first threshold for the precipitation height in the needle gaps of the cylinder card clothing.

[0085] Real-time detect the fiber height of the precipitation in the needle gaps of the cylinder card clothing and make a real-time judgment on whether the precipitation fiber height exceeds the first threshold. If it exceeds the first threshold, stop the carding action and clean the needle gaps. If it does not exceed the first threshold, continue with the real-time detection.

[0086] In another embodiment, the mixing and carding further includes the following steps:

[0087] Pre-obtain the initial position of the needle tips on the cylinder card clothing and determine a second threshold for the allowable offset range of the needle tips.

[0088] Real-time detect whether the position of the needle tips on the cylinder card clothing is offset beyond the second threshold. If the needle tips are offset beyond the second threshold, stop the carding action and perform needle tip correction or replace the cylinder card clothing. If it does not exceed the second threshold, continue with the real-time detection.

[0089] Embodiment 2 of the present invention provides a worsted spinning equipment for manufacturing staple fiber and tencel blended yarns, including a sliver making equipment, a double combing equipment, and a spinning equipment. Among them, the sliver making equipment includes a wool sliver making module for making wool fibers into wool slivers and a tencel sliver making module for making tencel fibers into tencel slivers; the double combing equipment includes a combing module for removing impurities in the wool ball, and a first gilling module for mixing and carding the wool sliver and the tencel sliver, and performing multiple drafting and carding operations on the wool ball after removing impurities to form a wool ball; the spinning equipment includes a second gilling module for drafting and gilling the wool ball into a sliver, and a spinning module for twisting the sliver into fine yarn.

[0090] In this embodiment, in the sliver making equipment, the wool sliver making module is a wool sliver making machine, which sequentially includes a raw material detection module, a feeding module, and a carding module according to the production operation sequence. The raw material detection module is used to pre-detect wool fibers, obtain relevant data, and simultaneously detect the quality of wool fibers; the feeding module includes an oil adding module, an antistatic agent adding module, and a water adding module, which are used to add oil, add antistatic agent, and add water according to the relevant data. Since the cohesion between wool fibers is small, the single fiber strength is low, and static electricity is easily generated, lubrication is required to reduce the breakage and damage of fibers during processing, and to increase the friction between fibers, making it easier for fibers to form slivers. Among them, lubrication is achieved by adding oil, adding antistatic agent, and adding water. Therefore, the feeding module includes an oil adding module, an antistatic agent adding module, and a water adding module. By the raw material detection module detecting wool fibers, obtaining relevant data including wool oil content, wool raw material moisture regain, target moisture regain, environmental humidity, environmental temperature, average wool length and fineness, etc., and performing the distribution or configuration of data including oil addition amount, antistatic agent addition amount, water addition amount, etc. In one embodiment, it can be manually configured according to the obtained data, or a distribution module can be added to automatically distribute according to the obtained data, and then add oil, antistatic agent amount, and water through the feeding module, and finally perform carding on it through the carding module to make wool slivers.

[0091] The tencel sliver making module is a tencel sliver making machine, which sequentially includes a loosening module, a carding module, and a drawing-in module according to the production operation sequence. The loosening module is used to loosen tencel fibers into a fluffy bundle shape; the carding module is used to further card and decompose the bundled tencel fibers into a single fiber state and preliminarily straighten and parallelize them; the drawing-in module is used to further draft, gill, and collect the tencel fibers into tencel slivers. Among them, the loosening module can be a loosener. The carding module can be a carding machine, and since the tencel is short, when the carding machine is carding, the distance between the working roller and the doffer and the cylinder should be less than the length of the tencel. The drawing-in module can be a drawing-in machine, which is used to draft and collect the tencel fibers carded by the carding machine. The roller distance in the drawing-in machine is less than the length of a single tencel fiber.

[0092] In this embodiment, in the double-combing equipment, the first gilling module can be gilling machines GN6, VSN, ST21, which are used to fully mix the wool sliver and the tencel sliver, perform drafting and carding on the mixed sliver, straighten and parallelize the fibers, make the sliver even in mass per unit length, tightly held together, reduce the unevenness rate, and at the same time control the weight per unit length of the sliver. The sliver after combing in the combing module is drafted and carded into a bobbin for easy storage and transportation, so as to facilitate the subsequent spinning stage. The combing module can be a combing machine ALFA, which is used to remove impurities such as short fibers, weeds, and neps that do not meet the process requirements.

[0093] In this embodiment, in the spinning equipment, the second gilling module can be a gilling machine, such as the cashmere screw type VSN gilling machine, which includes a flat strip with a mixing zone, a first gilling zone, a second gilling zone, a third gilling zone, and a fourth gilling zone respectively. Among them, the flat strips in the mixing zone to the third gilling zone use No. 9 flat strips with the densest needles. The No. 9 flat strips are used because the fineness of tencel is very fine, generally only 11μm, which is finer than 130s wool (known as golden wool with a fineness of 13.5μm). Therefore, No. 9 flat strips are used for full carding. If sparse flat strips are used, it will not play a great carding role. Since the length of tencel fibers is short, in order to produce smoothly, the roller gauge needs to be set smaller. Therefore, the roller gauges in the mixing zone, the first gilling zone, the second gilling zone, and the third gilling zone are set to 35, 35, 32, and 30 respectively. By adjusting the weight of the fed sliver and the draft multiple, the raw materials are fully mixed and carded, combined and drafted, and the weight per unit length is reduced, so that the tencel fibers are straightened and parallel, the sliver is even in mass per unit length, tightly held together, the unevenness rate is reduced, and at the same time, fine impurities and short fibers are removed. The fourth gilling zone further drafts and cards the tencel fiber sliver in the third gilling zone and reduces the weight per unit length. This roving process drafts the tencel fiber sliver into a sliver that can be used on the fine spinning module, and at the same time twists to make the roving have a certain tightness and strength. Subsequently, winding it into a yarn bobbin is convenient for storage, handling, and feeding the fine spinning machine. The fine spinning module can be a fine spinning machine, which adopts compact spinning technology, can reduce hairiness, increase the cohesion between yarns, improve the yarn strength, and obtain the final finished yarn.

[0094] In this embodiment, the carding module, the carding module, the combing module, the first gilling module, and the second gilling module further include a working roller, a flat strip arranged around the working roller along the rotation direction of the working roller, a flat strip cleaning module, and a needle tip detection module; the flat strip cleaning module is used to clean the gaps between the needles of the flat strip; the needle tip detection module is used to detect the state of the needle tips on the flat strip; the flat strip cleaning module is used to clean the gaps between the needles of the flat strip; the height detection module is used to detect the height of the flat strip; the needle tip detection module is used to detect the state of the flat strip;

[0095] Among them,

[0096] The card clothing cleaning module includes a first threshold setting module and a height detection module. The first threshold setting module is used to preset a first threshold for the precipitation height between the needle gaps of the cylinder card clothing. The height detection module is used to detect in real time the fiber height of the precipitation between the needle gaps of the cylinder card clothing and determine in real time whether the precipitation fiber height exceeds the first threshold. If it exceeds the first threshold, the carding action is stopped and the needle gaps are cleaned. If it does not exceed the first threshold, the real-time detection continues.

[0097] The needle head detection module includes a second threshold setting module and a needle head state detection module. The second threshold setting module is used to pre-obtain the initial position of the needle heads on the cylinder card clothing and determine a second threshold for the allowable deviation range of the needle heads. The needle head state detection module is used to detect in real time whether the position of the needle heads on the cylinder card clothing deviates beyond the second threshold. If the needle heads deviate beyond the second threshold, the carding action is stopped and the needle heads are corrected or the cylinder card clothing is replaced. If it does not exceed the second threshold, the real-time detection continues.
