Description

Technical Field

[0001] The invention relates to the technical field of felt processing, in particular to a wool felt processing method, felt and slippers. Background Art

[0002] At present, the felt upper materials for footwear on the market are mostly chemical fibers that are made into sheet-like felt fabrics through a needle punching process. After cutting, they are sewn or glued to the upper. Since the length of chemical fibers is very large, cross entanglement will occur during color mixing. The needle punching process further enhances the degree of fiber interweaving, thus forming a certain weaving density and thickness, which can produce better tensile strength and is not easy to cause deformation. When used as an upper material, it has a good shaping effect and does not deform after long-term wear.

[0003] The wool felt upper material needs to be added with a certain proportion of natural wool according to design requirements, usually more than 30%. This is because the length of wool itself is relatively small, and the wool fiber has a very low tensile strength and is easily broken. When interwoven with chemical fiber filaments, the weaving density and tensile strength are relatively poor. In particular, when the wool content reaches more than 50%, the wool felt sheet produced and used for the upper will easily deform after being worn for a long time, causing the shoes to become out of shape, which in turn leads to a poor fit and affects the wearing experience. Summary of the invention

[0004] In view of this, the purpose of the present invention is to overcome the deficiencies in the prior art and provide a wool felt processing method, felt and slippers.

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Because the wool content reaches a certain level, such as more than 50%, the blended wool felt material will have limited interweaving between the fibers, unable to form a good pulling force, and will be easily deformed; as an upper material, it will become loose due to deformation after being worn, causing the shoes to not fit the feet, thus affecting the wearing experience.

[0031] Based on this, Figure 1 As shown, the present invention provides a wool felt processing method, which is mainly used to produce a non-woven wool felt without glue adhesion to improve the overall tensile strength and stability of the felt. The wool felt processing method comprises the following steps:

[0032] Step S100, weighing materials to obtain base fabric, preset amounts of fiber yarn and wool.

[0033] Among them, before weighing the materials, different color fibers and dyed natural wool can be mixed according to the customer's color requirements for the felt and the set ratio of fiber silk and wool, so that the fiber silk and wool can be mixed to form the color required by the customer, thereby meeting the customer's required color and wool content ratio requirements.

[0034] Specifically, the wool and fiber yarn are weighed respectively according to the set ratio and total amount.

[0035] It should be noted that the base fabric in this step is a textile, which is a mesh structure with mesh holes. Specifically, the textile is a woven fabric with high strength made by using set yarn specifications and water weaving technology.

[0036] Step S200, laying out the fiber yarns and wool to form a mixed fiber layer.

[0037] Specifically, after the fiber filaments and wool are evenly mixed, the fiber filaments and wool are spread on a conveyor belt through a combing device to form a preset thickness. The laid fiber filaments and wool are folded and laid back and forth according to a certain number of layers to form a mixed fiber layer.

[0038] It can be understood that the fiber filaments and wool in the mixed fiber layer are arranged alternately.

[0039] Step S300: acupuncture: pre-treating the mixed fiber layer by acupuncture to form a blank.

[0040] Specifically, the laid out strip-shaped mixed fiber layer is pre-treated and needle-punched. The fibers are interwoven through at least three needle-punching processes to form a blank.

[0041] For example, if the needling process is three steps, the mixed fiber layer is first needled once from the upper side in the thickness direction, then needled once from the lower side in the thickness direction, and then needled once from the upper side of the mixed fiber layer.

[0042] It should be noted that the needle punching passes through the mixed fiber layer to further interweave the fiber filaments and wool to form a blank, so as to further improve the tensile strength and stability of the blank.

[0043] Step S400, compounding, after the blank material and the base fabric are stacked in sequence, a needle punching treatment is performed, and the blank material and the base fabric are interwoven to form a wool felt material.

[0044] In this embodiment, stacking the blank material and the base fabric in sequence means stacking the blank material and the base fabric alternately in sequence.

[0045] Exemplarily, if the blank and the base fabric are both one layer, the blank and the base fabric are stacked; if the blank is two layers and the base fabric is one layer, the base fabric is stacked between the two layers of blank.

[0046] Specifically, the needling treatment refers to needling the blank and the base fabric so that a portion of the blank passes through the base fabric and the blank and the base fabric are interwoven to form a wool felt material.

[0047] The blank is connected to the base fabric through physical interweaving to form an interweaving pulling force between the blank and the base fabric, thereby improving the tensile strength of the wool felt material, and also reducing the amount of wool and fiber, thereby reducing the weight of the wool felt material and reducing the cost of the wool felt material. The blank is physically interwoven with the base fabric through a needle punching process, so that the wool felt material has better air permeability.

[0048] Since the wool and fiber filaments are passed through the base cloth by needle punching to form the wool felt material, the knitting process is not only reduced, but also the overall weight of the wool felt is reduced, making the wool felt lighter and effectively improving the comfort of users. In addition, the processing method of the present application can also reduce the gluing process, which can not only reduce the production cost, but also improve the production efficiency and ensure the air permeability and warmth retention of the wool felt.

[0049] Step S500, hot rolling forming, hot rolling the wool felt material to form wool felt.

[0050] Specifically, the composite wool felt material is placed on a flat surface, compacted by a hot roller, and rolled up by ironing to form a wool felt sheet with a smoother surface and more uniform thickness, thereby facilitating the subsequent cutting and sewing of finished shoes, so as to make wool felt for footwear.

[0051] The wool felt processing method provided by the present invention uses a unique laminated needle punching process to place a high-strength textile between two layers of blanks, mix the wool and fiber filaments of the upper and lower layers, and needle punch them on the textile in the middle, thereby improving the tensile strength of the felt, and improving the stability and durability of the felt shape; at the same time, the weaving density is reduced, which can not only improve the air permeability and lightness of the wool felt, but also save more materials, lower the cost, and make it more breathable, light, and the upper has a good solid shape and is more durable. Through the physical interweaving processing method, the overall stability and strength of the felt can be improved while ensuring the overall flexibility of the felt.

[0052] At the same time, the wool felt processing method provided by the present application does not use any chemical adhesives during the processing process. It is a purely physical process, has no pollution and no chemical hazardous substance residue, and is more environmentally friendly and healthy.

[0053] It should be noted that the textile is made of inelastic material, that is, yarn with low elasticity, so as to ensure that the base fabric itself will not have obvious deformation, thereby strengthening the pulling force of wool and fiber yarns.

[0054] Specifically, the textile selected is 1680D single-strand Oxford cloth, which has moderate yarn strength, which not only ensures the passability of the needle, but also maintains the tensile strength of the wool felt itself.

[0055] In some embodiments of the present invention, in the weighing step, the wool content is x, wherein the value range of x is 0.3≤x≤1.

[0056] It can be understood that the value range of x can be any range of 0.3≤x≤1, 0.4≤x≤1, 0.5≤x≤1, 0.6≤x≤1, 0.7≤x≤1, 0.8≤x≤1 and 0.9≤x≤1, which can be specifically set according to actual conditions.

[0057] It is worth noting that wool felt upper materials need to be added with a certain proportion of natural wool according to design requirements, usually more than 30%, because the length of wool itself is relatively small, and when interwoven with chemical fiber filaments, the weaving density and tensile strength are relatively poor. In particular, when the wool content reaches more than 50%, the wool felt sheet used for the upper will easily deform after wearing for a long time, making the shoes out of shape.

[0058] On the basis of the physical properties of equal thickness and tensile strength, the present invention adopts a textile structure, the amount of wool and fiber yarn used can be significantly reduced, the unit weight can be reduced by at least 20%, and the material cost can be saved by at least 15%.

[0059] Since the gram weight is reduced, the wool felt upper material produced by the wool felt processing method provided by the present application is lighter.

[0060] Secondly, by adjusting the proportion of wool, the present application can improve the air permeability of the felt, making the felt more environmentally friendly, having greater tensile strength, and not deforming after long-term wear, so as to ensure the stability of the felt and thus enhance the user experience.

[0061] like Figure 2 As shown, in some embodiments of the present invention, before the paving step, the process includes:

[0062] Step S110, mixing, feeding a preset amount of fiber filaments and wool into a mixing box, and uniformly mixing the fiber filaments and wool through a mixing process.

[0063] Specifically, the fiber yarn and wool are sucked into a closed mixing box through a duct, and are broken up, fluffed and stirred to ensure that the natural wool and chemical fiber yarn are dispersed more evenly.

[0064] Due to packaging and transportation, the raw fiber is compressed and knotted, forming a mass or cake shape. Therefore, before the mixing step is performed, it also includes: opening, through the rollers on the opening machine, the fiber mass is pulled to loosen the fiber filaments and wool separately to avoid agglomeration, so as to ensure uniformity in the subsequent processing.

[0065] In some embodiments of the present invention, the needle punching pretreatment includes: knitting the mixed fiber layer up and down by means of needle plates to interweave the fiber filaments and the wool.

[0066] Among them, up and down reciprocating knitting refers to reciprocating knitting back and forth on the two back sides of the mixed fiber layer along the thickness direction of the mixed fiber layer, so that part of the fiber filaments and wool pass through the mesh of the base fabric during the knitting process and form an interlaced state with the base fabric.

[0067] In some embodiments of the present invention, the compounding step includes laminating the base fabric between two layers of blank material and then performing a needle punching treatment.

[0068] In this embodiment, the base fabric is stacked between two layers of stock, compacted and then needle-punched. It should be noted that the needle-punching step includes: first needle-punching from one side of the stock to one side of the base fabric, then needle-punching from one side of the base fabric to one side of the stock, and needle-punching alternately, so that part of the fiber filaments and wool in the stock can be staggered through the gaps of the base fabric, so that the stock and the base fabric form an interwoven structure, so as to improve the tensile strength and stability of the wool felt material.

[0069] Among them, the acupuncture frequency is 35-55 Hz, and the acupuncture depth is 12-16 mm.

[0070] In some embodiments of the present invention, in the hot rolling forming step, the hot rolling temperature is 150°C-200°C.

[0071] In addition, the hot rolling time is at least 30 seconds, and the hot rolling pressure is 8 to 10 MPa.

[0072] Table 1

[0073]

[0074]

[0075] It should be noted that in Table 1, serial numbers 1 to 3 are comparative examples, and serial number 4 is a wool felt cloth made by the wool felt processing method of the present application.

[0076] It is understandable that, for wool felt, the greater the pulling force, the longer the stretched length of the wool felt. Therefore, under the same pulling force, the smaller the stretched length of the wool felt, the greater the tensile strength of the wool felt and the better its stability.

[0077] It can be seen from Table 1 that, under the condition of the same tensile length, when the wool felt cloth made by the wool felt processing method of the present application has an average tensile strength greater than the average tensile strength of numbers 1 to 3, the tensile length of number 4 is much smaller than the tensile length of numbers 1 to 3, and the tensile rate of number 4 is much smaller than the tensile rate of numbers 1 to 3. In other words, the tensile strength of the wool felt cloth made by the wool felt processing method of the present application is much greater than the tensile strength of numbers 1 to 3, that is, the stability is better and more stable.

[0078] By stacking the wool felt material in double layers and adding a layer of strong textile in the middle, the wool and chemical fiber fibers on both sides can penetrate the textile and form an interwoven pulling force, thereby significantly improving its performance in resisting external pulling.

[0079] On the basis of the physical properties of equal thickness and tensile strength, the present invention adopts a textile structure, the amount of wool fiber and chemical fiber used can be significantly reduced, the unit weight can be reduced by about 20%, and the material cost can be saved by about 15%.

[0080] The wool felt shoe upper material produced by the wool felt processing method provided by the present invention is lighter, more breathable, more environmentally friendly, healthier, more solid, and does not deform after long-term wear.

[0081] like Figure 2 As shown, in some embodiments of the present invention, a felt is provided, which is made by the wool felt processing method described in any of the above embodiments.

[0082] It can be understood that the felt made by the wool felt processing method has the beneficial effects described in any of the above embodiments, which will not be described one by one here.

[0083] like Figure 2As shown, in some embodiments of the present invention, a pair of slippers is provided, which includes felt made by any of the wool felt processing methods described above or includes the felt described in any of the above embodiments.

[0084] It can be understood that the slippers provided by the present invention have the beneficial effects of the felt described in any of the above embodiments, which will not be described in detail here.

[0085] In this embodiment, by adjusting the parameters of the processing method, such as the frequency of the equipment, the depth of acupuncture and the thickness of the needle, the processed wool felt can meet the stress requirements of the upper of the finished shoe and will not deform after long-term wear.

[0086] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0087] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0088] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
