Double-sided fleece fabric and method of making the same

Abstract

This application relates to a double-sided plush fabric and its preparation method, and pertains to the textile field. This application employs a double-sided loop-cut plush machine to weave the first pile layer, connecting layer, and second pile layer of the double-sided plush fabric. The first and second pile layers are formed from pile yarns through a loop-cutting process. The connecting layer is formed by connecting the connecting layer yarns to the pile yarns of the first and second pile layers through a knitting structure. The connecting layer yarns tightly press against the pile yarns of the first and second pile layers, ensuring that the pile yarns are tightly attached together. In this configuration, the double-sided plush fabric not only guarantees the advantages of a plush structure, such as soft hand feel, warmth, and good abrasion resistance, but also fulfills the functional requirements of different pile types on both sides. Furthermore, the double-sided weft-knitted plush fabric improves upon the shedding phenomenon of ordinary plush fabrics, resulting in a softer and more skin-friendly overall fabric.

Description

Technical Field

[0001] This application relates to the field of textile technology, and in particular to a double-sided plush fabric and its preparation method. Background Technology

[0002] With the continuous improvement of textile technology, people's functional requirements for clothing fabrics are also constantly increasing. Double-sided plush fabric generally refers to fabrics with pile on both sides, fabrics with hair or pile. It refers to two pieces of pile fabric sewn together. The fabric is thick and dense, soft to the touch, and comfortable and warm to wear close to the skin.

[0003] However, double-sided fleece fabrics prepared using existing technologies are not environmentally friendly due to the composite process involved, and they are also prone to pilling and are relatively expensive. Summary of the Invention

[0004] The purpose of this application is to provide a double-sided fleece fabric and its preparation method, so as to solve the problems of high price, environmental unfriendliness and easy pilling of traditional double-sided fleece fabrics in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, this application provides a double-sided plush fabric, woven using a double-sided loop-cut plush machine, the double-sided plush fabric comprising:

[0007] The first surface includes a first pile layer formed by loop cutting of pile yarn;

[0008] The second surface includes a second pile layer formed by loop-cutting of pile yarn; and

[0009] A connecting layer, located between the first pile layer and the second pile layer, is formed by connecting the connecting layer yarns to the pile yarns of the first pile layer and the second pile layer through a braided structure.

[0010] The connecting layer yarn tightly presses against the pile yarns of the first pile layer and the second pile layer, so that the pile yarns can be tightly attached together.

[0011] In one possible implementation, the connecting layer is formed by connecting layer yarns and the pile yarns of the first pile layer and the second pile layer through a braided structure, including:

[0012] The plush yarn is knitted in a loop-like manner and does not unravel on the latch needle;

[0013] The connecting layer yarn is knitted in a normal loop. After the connecting layer yarn is looped, it is gathered with the plush yarn in a latch needle to obtain the connecting layer.

[0014] In one possible implementation, every ten rows in the double-sided plush fabric form a minimum weave repeat, with the loops and clumps on a partial number of paths arranged alternately in two ways.

[0015] In one possible implementation, the connecting layer yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns.

[0016] In one possible implementation, the plush yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns.

[0017] Secondly, this application provides a method for preparing a double-sided plush fabric, the method being applicable to any of the double-sided plush fabrics described above, the method employing a double-sided loop-cut plush machine for weaving, the method comprising:

[0018] S1. The plush yarn is not knitted in loops during knitting, but only knitted in loops on the latch needle;

[0019] S2. In response to the fact that the plush yarn is only knitted in loops on the latch needle, the connecting layer yarn is knitted in loops on the latch needle immediately following the knitting action of step S1 above. The knitted loops are pressed on the loops of the plush yarn to prevent the plush yarn from falling off and to form a connecting layer.

[0020] S3. In response to the formation of the connecting layer, the exposed plush yarn is cut by a needle, and a first plush layer and a second plush layer are formed on both sides of the connecting layer to obtain a double-sided plush fabric.

[0021] The connecting layer yarn tightly locks the pile yarn, securing the pile yarns of the first pile layer and the second pile layer to the fabric surface, making the fabric surface smooth and flat.

[0022] In one possible implementation, the needle plate of the double-sided loop-cut plush machine uses a tongue needle, and the syringe uses a knife needle;

[0023] The needle on the syringe has no tongue, only a blade, so it cannot loop the yarn. It is only used to cut the fibers of the yarn inserted into the needle hook, and is divided into high-heel needles according to the height of the heel.

[0024] In one possible implementation, during the weaving process of the double-sided plush fabric, plush yarn is first fed in for padding weaving, with the plush yarn simultaneously padding the latch needle and the cutting needle. Then, connecting layer yarn is fed in for padding weaving, with the connecting layer yarn only padding the latch needle and forming individual loop units.

[0025] In one possible implementation, the plush yarn pad is looped on the latch needle and locked to the connecting layer; the plush yarn pad is not looped on the cutting needle but the plush yarn is cut to form the first plush layer and the second plush layer.

[0026] In one possible implementation, the connecting layer yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns; the plush yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns.

[0027] The beneficial effects of the technical solution provided in this application include at least the following:

[0028] This application employs a double-sided loop-cut plush machine to knit the first pile layer, connecting layer, and second pile layer of a double-sided plush fabric. The first and second pile layers are formed from pile yarns through a loop-cutting process. The connecting layer is formed by connecting the yarns of the connecting layer with the pile yarns of the first and second pile layers through a knitting structure. The connecting layer yarns tightly press against the pile yarns of the first and second pile layers, ensuring the pile yarns adhere tightly together. In this configuration, the double-sided plush fabric not only maintains the advantages of a plush structure, such as soft hand feel, warmth, and abrasion resistance, but also fulfills the functional requirements of different pile types on both sides. Furthermore, the double-sided weft-knitted plush structure improves the shedding phenomenon of ordinary plush fabrics, resulting in a softer and more skin-friendly overall fabric. Additionally, this application provides a new needle arrangement and needle triangle arrangement for producing double-sided plush fabrics, facilitating efficient and streamlined production of double-sided plush fabrics and improving production efficiency.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] In this specification, identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions towards or away from a specific component, respectively. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "multiple" means two or more.

[0038] First, a brief introduction to the terms used in the embodiments of this application:

[0039] The double-sided cut loop plush machine is a type of "weft knitting circular machine". Its knitting principle is similar to that of the "double-sided weft knitting terry circular machine". Ground loops are formed on one set of needles, and elongated sinker arcs are formed on another set of needles or terry "sinkers". However, after the loops are formed, the elongated sinker arcs will be cut off by the cut needles or cut loop sinkers on the machine. After finishing, it can become a plush fabric.

[0040] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0041] Figure 1This illustration shows a structural schematic diagram of a double-sided plush fabric provided in an exemplary embodiment of this application. The double-sided plush fabric is woven using a double-sided loop-cut plush machine. The double-sided plush fabric includes a first surface, a second surface, and a connecting layer 2. The first surface includes a first pile layer 1 formed by loop-cutting of pile yarns. The second surface includes a second pile layer 3 formed by loop-cutting of pile yarns. The connecting layer 2 is located between the first pile layer 1 and the second pile layer 3. The connecting layer 2 is formed by connecting the connecting layer yarns and the pile yarns of the first pile layer 1 and the second pile layer 3 through a knitting structure. The connecting layer yarns tightly press the pile yarns of the first pile layer 1 and the second pile layer 3, so that the pile yarns can be tightly attached together.

[0042] Specifically, the aforementioned connecting layer 2 is formed by connecting the connecting layer yarns and the pile yarns of the first pile layer 1 and the second pile layer 3 through a knitted structure, including:

[0043] After the plush yarn is knitted in a loop-gathering manner, it is not unhooked on the latch needle; the connecting layer yarn is knitted in a normal loop-gathering manner, and after the connecting layer yarn is looped, it is gathered with the plush yarn on the latch needle to obtain the connecting layer.

[0044] In this embodiment, the double-sided plush fabric forms a minimum weave repeat of every ten rows, with the loops and coils alternating in two ways on a portion of the fabric. Optionally, the connecting layer yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns. Optionally, the plush yarn is one or more of chemical fibers, natural fibers, composite yarns, or functional yarns.

[0045] Figure 2 A flowchart illustrating a method for preparing a double-sided plush fabric according to an exemplary embodiment of this application is shown. This method is applicable to the double-sided plush fabric described above. The method employs a double-sided loop-cut plush machine for weaving, and specifically includes the following steps:

[0046] Step S1: The plush yarn is not knitted in loops during knitting, but only knitted in clusters on the latch needle;

[0047] Step S2: In response to the pile yarn being knitted in loops only on the latch needle, the connecting layer yarn is knitted in loops on the latch needle immediately following the knitting action of step S1 above. The knitted loops are pressed onto the pile yarn loops to prevent the pile yarn from falling off, thus forming the connecting layer.

[0048] Step S3: In response to the formation of the connecting layer, the exposed pile yarns are cut by the needle, and a first pile layer and a second pile layer are formed on both sides of the connecting layer to obtain a double-sided pile fabric.

[0049] Among them, the connecting layer yarn tightly locks the pile yarn, which tightly locks the pile yarn of the first pile layer and the second pile layer to the fabric surface, making the fabric surface smooth and flat.

[0050] In this embodiment of the application, the needle plate of the double-sided loop-cut plush machine uses a tongue needle, and the needle cylinder uses a knife needle; the knife needle on the needle cylinder has no needle tongue but only a blade, so that it cannot make the yarn loop, but is only used to cut the wool fibers inserted into the needle hook, and is divided into high-heel needles according to the height of the needle heel.

[0051] In the embodiments of this application, during the weaving process of the double-sided plush fabric, plush yarn is first fed in for padding weaving, and the plush yarn is simultaneously padded on the latch needle and the cutting needle. Then, connecting layer yarn is fed in for padding weaving, and the connecting layer yarn is only padded on the latch needle and forms a series of loop units.

[0052] It is worth mentioning that the function of the plush yarn pad on the latch needle and the cutting needle is as follows: the plush yarn pad forms a loop on the latch needle and locks with the connecting layer 2; the plush yarn pad does not form a loop on the cutting needle but cuts the plush yarn, forming the first plush layer 1 and the second plush layer 3. At the same time, the existence of the double-sided plush fabric's double-sided structure means that the plush yarn on both sides of the fabric will be cut by the cutting needle, thus forming a double-sided plush structure on both sides of the fabric.

[0053] Optionally, the connecting layer yarn is made of one or more of chemical fibers, natural fibers, composite yarns, or functional yarns; the plush yarn is made of one or more of chemical fibers, natural fibers, composite yarns, or functional yarns.

[0054] To better understand this application, the following description, in conjunction with the accompanying drawings and two specific embodiments, provides a further explanation. It should be noted that the embodiments described herein are merely some examples of this application and do not limit the scope of protection of this application. Specific Implementation Example 1:

[0056] Figure 3 The diagram illustrates the knitting needle types and triangular knitting diagrams of the first and second pile layers in the preparation method of the double-sided plush fabric provided in Specific Embodiment 1 of this application. The diagram shows four types of knitting needles used for knitting the double-sided plush fabric. To easily distinguish between cylinder knitting needles and disc knitting needles, they are named as follows: 1 represents a high-heel needle, 2 represents a low-heel needle, N represents a disc knitting needle, and D represents a disc knitting needle; n represents a cylinder knitting needle, and d represents a disc knitting needle. Triangular modularization is also proposed, with the triangular arrangement of the first pile layer consisting of F1-F5 and the triangular arrangement of the second pile layer consisting of B1-B5.

[0057] Figure 4 The diagram shows the minimum cycle needle arrangement of the method for preparing double-sided plush fabric according to a specific embodiment of this application; Figure 5The diagram shows the process weaving diagram of the preparation method of the double-sided plush fabric provided in the first specific embodiment of this application.

[0058] It should be noted that, Figure 4 The fabric needs to be knitted on a double-sided cut-loop plush knitting machine equipped with a cylinder and needle plate. The double-sided cut-loop plush knitting machine knits double-sided plush fabric, and the knitting process involves gathering, forming, and cutting loops. Therefore, the needles on the double-sided cut-loop plush knitting machine are like... Figure 1 As shown, it has both a regular tongue needle and a scalpel needle. Figure 4 The syringe needle disc in the middle is specifically designed with needles arranged in a minimum horizontal loop of six needles. Figure 4 This indicates that the minimum number of rows in the organizational structure is 10, and it also indicates the knitting pattern of each needle in each loop system. Figure 3 The diagram shows a triangular track for knitting needles. Each needle cylinder and needle plate has four needle tracks, and four types of needles occupy one track to complete different knitting actions.

[0059] To further explain, Figure 4 The arrangement of the knitting needles in the middle, according to Figure 3 The triangular modules are used for needle movement. In the first pile layer, F1 and F3 are the weaving triangles for the pile yarn, ultimately forming the first pile layer on the front of the fabric, which is the pile yarn area; F2 and F4 are the weaving triangles for the connecting layer yarn, forming loops, which are the connecting units. F5 is the lower needle exiting, cutting the pile yarn to form the first pile layer, which is the cutting area. In the second pile layer, B1 and B3 are the weaving triangles for the pile yarn, ultimately forming the second pile layer on the reverse side of the fabric, which is the pile yarn area; B2 and B4 are the weaving triangles for the connecting layer yarn, forming loops, which are the connecting units. B5 is the upper needle exiting, cutting the pile yarn to form the second pile layer, which is the cutting area. Modular integration through the triangular arrangement of the front and reverse loops facilitates triangle replacement on the machine, accelerating the convenience and industrialization of weaving.

[0060] Specifically, as shown in Figure 5, a double-sided loop-cut plush knitting machine with a special structure featuring four upper needle tracks and four lower needle tracks produces a double-sided plush fabric with plush yarn A on the front and plush yarn B on the back. This fabric is composed of three interwoven yarns: connecting layer yarn, plush yarn A, and plush yarn B. The fabric's weave structure uses a small-scale repeat pattern with a height of 10 and a width of 6. (The text repeats itself here.) Figure 5 As shown, in the smallest weave cycle of a complete fabric structure, there are 6 cylinder needles and 6 dial needles. The specific knitting process is as follows:

[0061] First, thread the plush yarn A and knit in a tucked loop on the high-heeled needle of the needle plate N2. Then, knit in a tucked loop on the needle tube knife needle d2. After the tucked loop is completed, do not unloop the loop. Insert the plush yarn A into the latch needle.

[0062] The second thread is a connecting layer yarn, which is knitted in loops on the low heel needles of needle plate N1 and the high heel needles of needle plate N2. The loops of the connecting layer yarn are pressed on the loops of the first thread, which can tightly lock the plush yarn A of the first thread and also serve as a connection.

[0063] The third thread is made of plush yarn A. It is knitted in a loop on the low heel needle of the needle plate N1. It is also knitted in a loop on the knife needle d1 on the needle cylinder. After the loop knitting is completed, the loop is not removed. Plush yarn A is inserted into the latch needle.

[0064] The fourth threaded connecting layer yarn is knitted in loops on the low heel needles of needle plate N1 and the high heel needles of needle plate N2; the loops of the connecting layer yarn are pressed on the loops of the third thread, which can tightly lock the fluffy yarn A of the third thread and also serve as a connection.

[0065] The fifth cutting needle extends fully, cutting the pile yarn A and forming the first pile layer on the fabric surface;

[0066] The sixth thread is the plush yarn B. It is used for tuck knitting on the low-heel needle of the needle cylinder n2. It is also used for tuck knitting on the knife needle D1 on the needle plate. After the tuck knitting is completed, the loop is not removed. The plush yarn B is inserted into the latch needle.

[0067] The seventh thread is a connecting layer yarn (knitted in loops on the low heel needle of cylinder n2 and the high heel needle of cylinder n1; the loops of the connecting layer yarn are pressed on the loops of the sixth thread, which can tightly lock the plush yarn B of the sixth thread and also serve as a connection).

[0068] The eighth thread is the plush yarn B. It is used for tuck knitting on the high-heeled needle of the needle cylinder n1. It is also used for tuck knitting on the knife needle D2 on the needle plate. After the tuck knitting is completed, the loop is not removed. The plush yarn B is inserted into the latch needle.

[0069] The ninth thread is threaded through the connecting layer yarn and knitted in loops on the low heel needle of cylinder n2 and the high heel needle of cylinder n1; the loops of the connecting layer yarn are pressed on the loops of the sixth thread, which can tightly lock the plush yarn B from the sixth to the eighth thread and also serve as a connection.

[0070] On the tenth path, the cutting needle fully extends, cutting the loop of the plush yarn B to form the second plush layer.

[0071] In this design, two looping units form a loop row. The first and third loops are positioned differently, and the second, fourth, seventh, and ninth loops overlap each other, thus creating two different longitudinal rows on the fabric surface, which better locks in the plush yarn. The four looping rows use less yarn, resulting in a lighter fabric surface density.

[0072] In this embodiment, the prepared double-sided plush fabric has different pile types on both sides and forms different loop rows on the fabric surface, giving the fabric a good pile-locking effect, as well as good abrasion resistance and warmth retention. This fabric can be used to make clothing, toys, bedding, and interior decoration products. Specific Implementation Example 2:

[0074] This embodiment modifies the arrangement of the tongue needle and the knife needle, as well as the length of the plush yarn on the fabric surface, based on the first embodiment.

[0075] Figure 6 This illustration shows the minimum cycle needle arrangement diagram of the double-sided plush fabric preparation method provided in Embodiment 2 of this application. Specifically, the needle cylinder and needle plate are configured with pin-needle arrangements, with 12 pin-needles forming one minimum horizontal row cycle. Simultaneously, following a modular triangular arrangement, ten horizontal rows complete one pattern. Two different types of yarn (plush yarn and connecting layer yarn) are used, according to... Figure 6 The knitting needles are arranged and woven in a modular triangular pattern, resulting in fabric with yarns of varying lengths.

[0076] The change in the needle arrangement also alters the pile distribution in the pile layer of the double-sided plush fabric, changing the pile distribution from one-alternate-one to two-alternate-one; compared with Specific Embodiment 1, the pile becomes of varying lengths, changing the fabric surface effect and feel.

[0077] In summary, this application addresses the environmental issues of existing double-sided plush fabrics by providing a double-sided plush fabric and its preparation method, improving the pile-locking effect and reducing pile shedding; it also reduces the environmental impact of the fabric. Furthermore, it provides a new needle arrangement and triangular needle arrangement for producing double-sided plush fabric, facilitating efficient and streamlined production and improving production efficiency. Finally, it provides a novel fabric structure for producing double-sided plush fabric.

[0078] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
