Description

Technical Field

[0001] The invention relates to the technical field of bed core manufacturing, and in particular to an alpaca wool bed core manufacturing process, a bed core and a mattress. Background Art

[0002] Since alpaca wool (also known as Alpaca, a camel wool fiber) has natural characteristics such as softness, lightness, smoothness, elasticity, not easy to deform, warmth and breathability, alpaca wool is very suitable for use in bed cores. In the existing alpaca wool bed core production process, alpaca wool fiber and polyester fiber are weighed according to the required proportion, and then processed through processes such as opening and mixing, combing into a net and high-temperature baking to produce an alpaca wool bed core.

[0003] However, since alpaca wool is expensive and thin, the fibers are easily damaged when combing it evenly, resulting in the alpaca wool not being able to retain its own characteristics well. As a result, the thermal insulation, softness and other properties of the bed core will deteriorate and cannot meet the needs of users. Moreover, for textile companies, the pass rate of the bed core will decrease, while the production cost and material quantity of the bed core will increase. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides an alpaca wool bed core manufacturing process, a bed core and a mattress, which can prevent the alpaca wool from being damaged, ensure a good combing effect, and make the bed core have good heat preservation and softness.

[0005] The first embodiment of the present invention provides a process for manufacturing an alpaca wool mattress core, which comprises the following steps:

[0006] Adjust the setting mode of the tooth tips of the card cloths in the cylinder, doffer and multiple groups of working rollers of the carding machine, wherein the setting mode of the tooth tips of the card cloths includes: the angle of the tooth tips of the card cloths of the cylinder is 15°, the angle of the tooth tips of the card cloths of the doffer is 35°, the angle of the tooth tips of the card cloths of the multiple groups of working rollers is 30°, and the directions of the tooth tips of the card cloths of the cylinder are opposite to the directions of the tooth tips of the card cloths of the doffer and the directions of the tooth tips of the card cloths of the multiple groups of working rollers;

[0007] The cylinder, the doffer and the multiple groups of working rollers are driven to rotate in the same direction, and the linear speeds of the cylinder, the doffer and the multiple groups of working rollers are adjusted, wherein the linear speed ratio of the cylinder and the doffer is 30:1, the multiple groups of working rollers are arranged at intervals along the circumference of the cylinder, and the linear speeds of the multiple groups of working rollers are reduced in sequence according to the combing order of the working rollers.

[0008] The alpaca wool bed core manufacturing process according to the embodiment of the first aspect of the present invention has at least the following beneficial effects: in the combing process of the alpaca wool bed core, the cylinder, multiple groups of working rollers and doffer all rotate in the same direction, the cylinder is opposite to the doffer and multiple groups of working rollers in the direction of the needle cloth tooth tip, the linear speeds of the multiple groups of working rollers are reduced in sequence according to the combing order of the working rollers, so that the multiple groups of working rollers perform multi-stage combing of the cotton web on the cylinder from fast to slow through the linear speed difference principle, so as to comb the cotton web evenly; moreover, the doffer grabs the cotton web from the cylinder through the linear speed difference principle and turns it into a web. The linear speed ratio of the cylinder and the doffer is related to the web structure. Setting the linear speed ratio to a set value of 30:1 can avoid damage to the cotton web such as breaking, and prevent the fibers gathered into the cotton web from pilling, resulting in poor combing effect.

[0009] When combing the cotton web using the principle of linear speed difference, if the angle of the tooth tip of the card clothing of the cylinder is greater than 15°, the separation will be poor, the fiber tearing will be strong, and the alpaca wool fiber will be easily damaged; if the angle of the tooth tip of the card clothing of the cylinder is less than 15°, the combing effect will be reduced; if the angle of the tooth tip of the card clothing of the doffer is greater than 35°, the doffer grabs a large amount of cotton web from the cylinder, which is not easy to separate, resulting in poor rotation of the cotton web; if the angle of the tooth tip of the card clothing of the doffer is less than 35°, the doffer grabs a small amount of cotton, resulting in a large amount of cotton returned to the cylinder, causing the combing effect to deteriorate; if the angle of the tooth tip of the card clothing of multiple sets of working rollers is greater than 30°, the grabbing amount is large, resulting in poor combing effect; if the angle of the tooth tip of the card clothing of multiple sets of working rollers is less than 30°, it is not easy to grab fibers from the cylinder, affecting the combing effect.

[0010] The present invention can ensure a good combing effect through the above steps, and can also ensure that the alpaca wool fibers are not damaged, and can give full play to their natural characteristics, so that the bed core has excellent heat preservation and softness.

[0011] In some embodiments of the present invention, the adjusting of the linear speeds of the cylinder, the doffer and the multiple groups of working rollers comprises the following steps: adjusting the linear speed of the cylinder to 900 m / min, adjusting the linear speed of the doffer to 30 m / min, and adjusting the linear speeds of the multiple groups of working rollers to 22 m / min, 20 m / min, 18 m / min, 17 m / min and 16 m / min in sequence according to the combing order of the working rollers.

[0012] In some embodiments of the present invention, before driving the cylinder, the doffer and the multiple groups of working rollers to rotate in the same direction, the following step is also included: adjusting the spacing of the doffer of the carding machine relative to the cylinder, wherein the doffer includes an upper doffer and a lower doffer, and the spacing between the upper doffer and the cylinder is greater than the spacing between the lower doffer and the cylinder.

[0013] In some embodiments of the present invention, the step of adjusting the gauge between the doffer of the carding machine and the cylinder comprises the following steps: adjusting the gauge between the upper doffer and the cylinder to 29 wires, and adjusting the gauge between the lower doffer and the cylinder to 12 wires.

[0014] In some embodiments of the present invention, before driving the cylinder, the doffer and the multiple groups of working rollers to rotate in the same direction, the following step is also included: adjusting the spacing of the multiple groups of working rollers relative to the cylinder, wherein the spacing of the multiple groups of working rollers and the cylinder is reduced in sequence according to the combing order of the working rollers.

[0015] In some embodiments of the present invention, the adjusting of the spacing between the multiple groups of working rollers and the cylinder comprises the following steps: setting the spacing between the multiple groups of working rollers and the cylinder to 31 wires, 28 wires, 26 wires, 24 wires and 22 wires in the order of combing the working rollers.

[0016] In some embodiments of the present invention, before driving the cylinder, the doffer and the multiple groups of working rollers to rotate in the same direction, the following steps are also included: humidifying and evenly mixing the alpaca wool fiber and the polyester fiber; controlling the humidity at 65% through moisture regain treatment.

[0017] In some embodiments of the present invention, the moisture conditioning treatment comprises the following step: subjecting the mixture of alpaca wool fibers and polyester fibers to moisture conditioning treatment for 8 hours.

[0018] A second aspect of the present invention provides a bed core, which is made by the alpaca wool bed core manufacturing process as described in the first aspect of the present invention.

[0019] A third aspect of the present invention provides a mattress, which includes the bed core described in the second aspect of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] Reference below Figures 1 to 4 The invention describes an alpaca wool bed core manufacturing process, a bed core and a mattress according to an embodiment of the invention.

[0029] like Figure 1 As shown, the alpaca wool bed core manufacturing process according to the first embodiment of the present invention can avoid the damage of the alpaca wool and ensure a good combing effect, so that the bed core has good heat preservation and softness.

[0030] The alpaca wool mattress core manufacturing process of this embodiment includes the following steps:

[0031] Step S10: adjusting the setting mode of the tooth tips of the card cloths in the cylinder, the doffer and the multiple groups of working rollers of the carding machine, wherein the setting mode of the tooth tips of the card cloths includes: the angle of the tooth tips of the card cloths of the cylinder is 15°, the angle of the tooth tips of the card cloths of the doffer is 35°, the angle of the tooth tips of the card cloths of the multiple groups of working rollers is 30°, and the directions of the tooth tips of the card cloths of the cylinder are opposite to the directions of the tooth tips of the card cloths of the doffer and the directions of the tooth tips of the card cloths of the multiple groups of working rollers.

[0032] Step S20: driving the cylinder, the doffer and the multiple groups of working rollers to rotate in the same direction, and adjusting the linear speeds of the cylinder, the doffer and the multiple groups of working rollers, wherein the linear speed ratio of the cylinder to the doffer is 30:1, the multiple groups of working rollers are arranged at intervals along the circumference of the cylinder, and the linear speeds of the multiple groups of working rollers are reduced in sequence according to the combing order of the working rollers.

[0033] It is understandable that the carding machine is a key equipment for the production of alpaca wool bed cores, which generally include alpaca wool fibers and polyester fibers. During the working process of the carding machine, the fibers on the feed curtain are first slowly and continuously sent to the opening part, and the fibers are initially opened (also known as pre-combing) by two sets of feed rollers and licker-in rollers. Then, the opened fibers are sent to the cylinder, and further combed by multiple sets of working rollers. The combed fibers are condensed into a cotton web by the doffer, and then stripped by the stripping roller to form a certain amount of fiber web.

[0034] The structure of the existing carding machine includes a cylinder, a licker-in roller, a combing roller, a doffer, a stripping roller and multiple groups of working rollers. Among them, the cylinder is used to transport the cotton web, and the doffer is used to grab the cotton web and output it into a web. The multiple groups of working rollers include a first group of working rollers, a second group of working rollers, a third group of working rollers, a fourth group of working rollers and a fifth group of working rollers. The first group of working rollers to the fifth group of working rollers are arranged in sequence along the circumference of the cylinder at a certain interval. The function of each group of working rollers is to comb the fibers on the cylinder. According to the combing sequence of the working rollers, the first group of working rollers combs the fibers on the cylinder first, followed by the second group of working rollers, and according to the order of arrangement, the fifth group of working rollers completes the combing. The linear speed of each group of working rollers is less than the linear speed of the cylinder, and less than the linear speed of the doffer.

[0035] Under high-speed rotation, the combed fibers on the needle surface of the cylinder will be lifted up by the centrifugal force. At this time, they can be held by the tips of the needle cloth of the doffer rotating at a relatively low speed, so that the fibers are transferred from the needle surface of the cylinder to the needle surface of the doffer and condensed into a fiber web. The diameter of the cylinder can be set to 1230 mm, the diameter of the working roller can be set to 160 mm, and the diameter of the doffer can be set to 512 mm.

[0036] The embodiment of the present invention makes unique improvements to the setting mode of the tooth tips of the card cloths adopted by the cylinder, the doffer and the multiple groups of working rollers while using the existing carding machine. Since the specific setting of the tooth tip angles of the card cloths of the cylinder, the tooth tip angles of the multiple groups of working rollers and the tooth tip angles of the card cloths of the doffer will affect the degree of damage to the alpaca wool fiber and the carding effect, the embodiment specifically defines the tooth tip angles of the card cloths so that they influence and complement each other, thereby improving the carding effect, ensuring that the alpaca wool fiber itself is intact, and allowing the alpaca wool to retain its natural characteristics.

[0037] Moreover, the tooth tips of the cylinder's card clothing are arranged opposite to the tooth tips of the doffer's card clothing, and the tooth tips of the cylinder's card clothing are also arranged opposite to the tooth tips of the card clothing of each group of working rollers. Specifically, if the tooth tips of the cylinder's card clothing are evenly arranged clockwise, the tooth tips of the doffer's card clothing and the tooth tips of the working rollers are evenly arranged counterclockwise.

[0038] Specifically, setting the angle of the tooth tip of the card clothing of the cylinder to 15° can ensure a good separation effect and a good fiber combing effect. Setting the angle of the tooth tip of the card clothing of multiple groups of working rollers to 30° can ensure that the working rollers can easily grab the fibers on the cylinder and have a good combing effect. Setting the angle of the tooth tip of the card clothing of the doffer to 35° can ensure that the doffer has an appropriate amount of grabbing and can smoothly turn out the cotton web.

[0039] It is understandable that if the tooth tip angle of the cylinder card clothing is set to be greater than 15°, there will be problems such as poor separation performance and strong fiber tearing, which makes it difficult for the working roller and doffer to grab the fiber from the cylinder. Moreover, when the working roller and doffer grab the fiber from the cylinder, the alpaca fiber is easily damaged, causing the alpaca fiber to lose its natural characteristics such as flexibility and warmth. If the tooth tip angle of the cylinder card clothing is set to be less than 15°, although the separation performance is good, it is easy for the doffer and the working roller to grab the fiber from the cylinder, but the combing effect on the fiber is poor.

[0040] If the tooth tip angle of the card clothing of each set of working rollers is set to be greater than 30°, the gripping amount of the working rollers is too large, and the combing effect of the fibers on the cylinder is poor. If the tooth tip angle of the card clothing of each set of working rollers is set to be less than 30°, the working rollers are not easy to grab the fibers from the cylinder, which will also affect the combing effect.

[0041] If the tip angle of the doffer's card clothing is set to more than 35°, the doffer's grabbing amount is large, which is not easy to separate, resulting in the cotton web being not smoothly turned out. If the tip angle of the doffer's card clothing is set to less than 35°, the doffer's grabbing amount is small, resulting in a large amount of cotton returned to the cylinder, which reduces the combing effect.

[0042] In the manufacturing process of the alpaca wool bed core of the present embodiment, since the cylinder, multiple groups of working rollers and doffer all rotate in the same direction, for example, clockwise, the cylinder is opposite to the doffer and the multiple groups of working rollers in the direction of the needle cloth tooth tips, and along the rotation direction of the cylinder, the linear speeds of the multiple groups of working rollers are reduced in sequence according to the combing order of the working rollers. Therefore, the multiple groups of working rollers perform multi-stage combing on the cotton web on the cylinder in the order from fast to slow according to the principle of linear speed difference, so that the cotton web can be combed evenly, so that the cylinder can bring the combed cotton web to the doffer.

[0043] Moreover, the doffer grabs and condenses a cotton web of a certain thickness from the cylinder through the principle of linear speed difference, and turns it out into a web. The linear speed ratio of the cylinder and the doffer is related to the web structure. By setting the linear speed ratio to a set value of 30:1, it can avoid damage to the cotton web such as breaking, and prevent the fibers gathered into the cotton web from pilling, resulting in poor combing effect.

[0044] When combing the cotton web using the principle of linear speed difference, if the angle of the tooth tip of the card clothing of the cylinder is greater than 15°, the separation will be poor, the fiber tearing will be strong, and the alpaca wool fiber will be easily damaged; if the angle of the tooth tip of the card clothing of the cylinder is less than 15°, the combing effect will be reduced; if the angle of the tooth tip of the card clothing of the doffer is greater than 35°, the doffer grabs a large amount of cotton web from the cylinder, which is not easy to separate, resulting in poor rotation of the cotton web; if the angle of the tooth tip of the card clothing of the doffer is less than 35°, the doffer grabs a small amount of cotton, resulting in a large amount of cotton returned to the cylinder, causing the combing effect to deteriorate; if the angle of the tooth tip of the card clothing of multiple sets of working rollers is greater than 30°, the grabbing amount is large, resulting in poor combing effect; if the angle of the tooth tip of the card clothing of multiple sets of working rollers is less than 30°, it is not easy to grab fibers from the cylinder, affecting the combing effect.

[0045] The present invention can ensure a good combing effect through the above steps, and can also ensure that the alpaca wool fibers are not damaged, and can give full play to their natural characteristics, so that the bed core has excellent heat preservation and softness.

[0046] In a specific embodiment, in step S20, specifically, the step of adjusting the linear speeds of the cylinder, the doffer and multiple groups of working rolls includes the following steps: adjusting the linear speed of the cylinder to 900 m / min, adjusting the linear speed of the doffer to 30 m / min, and adjusting the linear speeds of the multiple groups of working rolls to 22 m / min, 20 m / min, 18 m / min, 17 m / min and 16 m / min in the order of combing the working rolls.

[0047] Specifically, multiple groups of working rolls are divided according to the combing order of the working rolls, namely the first group of working rolls, the second group of working rolls, the third group of working rolls, the fourth group of working rolls and the fifth group of working rolls. The linear speed of the first group of working rolls is set to 22 meters / minute, the linear speed of the second group of working rolls is set to 20 meters / minute, the linear speed of the third group of working rolls is set to 18 meters / minute, the linear speed of the fourth group of working rolls is set to 17 meters / minute, and the linear speed of the fifth group of working rolls is set to 16 meters / minute.

[0048] It can be understood that when the cylinder and doffer adopt the above-mentioned linear speeds, multiple groups of working rollers adopt the above-mentioned specific linear speeds, so that the multiple groups of working rollers can perform five-level combing from fast to slow on the fibers attached to the cylinder through the principle of linear speed difference, which can improve the separation degree of alpaca wool fibers, prevent the cotton web from being broken and damaged, and at the same time, improve the combing effect and avoid pilling of fibers gathered into the cotton web.

[0049] like Figure 2 As shown, the alpaca wool bed core manufacturing process provided in Example 2 according to the first aspect of the present invention is different from Example 1 in that: before step S20, it also includes step S11.

[0050] In step S20, specifically, before the step of driving the cylinder, the doffer and the plurality of working rollers to rotate in the same direction, the alpaca wool bed core manufacturing process further includes the following steps:

[0051] Step S11: adjusting the spacing between the doffer of the carding machine and the cylinder, wherein the doffer includes an upper doffer and a lower doffer, and the spacing between the upper doffer and the cylinder is greater than the spacing between the lower doffer and the cylinder.

[0052] In a specific embodiment, in step S11, specifically, the step of adjusting the gauge between the doffer of the carding machine and the cylinder includes the following steps: adjusting the gauge between the upper doffer and the cylinder to 29 wires, and adjusting the gauge between the lower doffer and the cylinder to 12 wires.

[0053] It is understandable that step S11 can be after step S10 or before step S10. Before starting the combing process, adjust the spacing relationship between the cylinder and the doffer. Specifically, the spacing between the upper doffer and the cylinder is large, and the spacing between the lower doffer and the cylinder is small, so that the upper doffer and the lower doffer can both smoothly grab the cotton web on the cylinder and turn it into a web respectively. Moreover, the upper doffer first grabs the combed cotton web from the cylinder and turns it into a web. Since the amount of cotton web on the cylinder decreases, the spacing between the lower doffer and the cylinder is reduced, so that the lower doffer can grab the combed cotton web from the cylinder. Therefore, the combing machine can output two layers of cotton web through the upper doffer and the lower doffer. The upper doffer and the lower doffer adopt the above-mentioned spacing, so that the upper doffer and the lower doffer can evenly demand the amount of cotton to better provide the cotton web for the next process.

[0054] like Figure 3 As shown, the alpaca wool bed core manufacturing process provided in Example 3 according to the first aspect of the present invention is different from Example 2 in that: before step S20, it also includes step S12.

[0055] In step S12, specifically, before the step of driving the cylinder, the doffer and the plurality of working rolls to rotate in the same direction, the following steps are also included:

[0056] Step S12: adjusting the spacing between the plurality of working rollers and the cylinder, wherein the spacing between the plurality of working rollers and the cylinder is reduced in sequence according to the combing sequence of the working rollers.

[0057] In a specific embodiment, in step S12, specifically, the step of adjusting the spacing between multiple groups of working rollers and the cylinder includes the following steps: adjusting the spacing between multiple groups of working rollers and the cylinder to 31 wires, 28 wires, 26 wires, 24 wires and 22 wires in the order of combing the working rollers.

[0058] Since the first to fifth groups of working rollers comb the fibers on the cylinder in sequence, the first to fifth groups of working rollers are set to reduce the distance between them and the cylinder in sequence, that is, the distance between the working rollers and the cylinder is gradually reduced according to the combing order of the working rollers. Among them, the distance between the first group of working rollers and the cylinder is set to 31 wires, the distance between the second group of working rollers and the cylinder is set to 28 wires, the distance between the third group of working rollers and the cylinder is set to 26 wires, the distance between the fourth group of working rollers and the cylinder is set to 24 wires, and the distance between the fifth group of working rollers and the cylinder is set to 22 wires.

[0059] Step S12 may be performed before step S11 or after step S11.

[0060] It is understandable that, since the first group of working rollers combs the fibers on the cylinder first, the fibers attached to the cylinder are messy and uneven before passing through the first group of working rollers. Therefore, it is necessary to set the spacing between the first group of working rollers and the cylinder to the maximum value among the spacings between all working rollers and the cylinder, so that the first group of working rollers can comb the fibers. After combing, the fibers on the cylinder gradually become orderly and uniform. Therefore, the spacing between the working rollers and the cylinder can be reduced in sequence according to the combing sequence of the working rollers. By adopting the above setting of the spacing (i.e., the spacing) between the working rollers and the cylinder, the dispersion of the alpaca fibers during the combing process can be improved, and the quality of the alpaca fibers can be effectively improved. In addition, through multi-stage combing and gradually reducing the spacing, the cotton web can be combed more evenly.

[0061] like Figure 4 As shown, the alpaca wool bed core manufacturing process provided in Example 4 according to the first aspect of the present invention is different from Example 3 in that before step S20, it also includes step S13 and step S14.

[0062] In step S20, specifically, before the step of driving the cylinder, the doffer and the plurality of working rolls to rotate in the same direction, the following steps are also included:

[0063] Step S13: humidifying and uniformly mixing the alpaca wool fibers and the polyester fibers.

[0064] Step S14: Control the humidity at 65% through moisture conditioning treatment.

[0065] In a specific embodiment, in step S14, specifically, the step of moisture regaining treatment includes the following steps: performing moisture regaining treatment on the mixture of alpaca wool fiber and polyester fiber for 8 hours.

[0066] Alpaca fiber is a natural three-dimensional hollow fiber, and polyester fiber is a 4080 low melting point fiber. The dryness and humidity of the working environment will affect the toughness of the alpaca fiber, so the humidity needs to be controlled. The alpaca fiber and polyester fiber can be humidified by spraying, and then the mixture of the alpaca fiber and polyester fiber is evenly mixed. Then, the evenly mixed alpaca fiber and polyester fiber are subjected to moisture recovery treatment. The moisture recovery treatment lasts for eight hours to effectively control the humidity, thereby enhancing the toughness of the alpaca fiber, avoiding the damage of the alpaca fiber being easily broken, and improving the combing effect.

[0067] In addition, the bed core according to the first embodiment of the second aspect of the present invention is made by the alpaca wool bed core manufacturing process of the first embodiment.

[0068] The alpaca wool bed core manufacturing process of the first embodiment is used to manufacture the alpaca wool bed core, which can prevent the alpaca wool fibers from being damaged during the combing process and ensure a good combing effect of the cotton net, so that the alpaca wool bed core has good thermal insulation and softness, meets the needs of current users, and improves usage satisfaction.

[0069] In addition, the mattress according to the first embodiment of the third aspect of the present invention includes the bed core of the second embodiment.

[0070] The mattress also includes a bed cover, which is arranged on the bed core. The mattress adopts the bed core, can provide users with excellent heat preservation and softness, and can improve the sleep quality of users.
