Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to an anti-curling fabric and a preparation method and application thereof. Background Art

[0002] The main performance requirements for fabrics in the collars and cuffs of shirts and other clothing include wearing comfort and smooth appearance. However, collar and cuff fabrics generally have the problem of curling and wrinkling after repeated washing and cannot maintain the original smoothness and stiffness, which has a negative impact on their appearance and greatly reduces the image of the wearer.

[0003] The prior art often improves its shape retention by partially inserting a hard insert. For example, CN114903222A discloses that when cutting and sewing, an opening is reserved at the collar tip of the inner collar surface, and a strip-shaped hard polyurethane plastic anti-curling device is inserted into the opening when wearing to prevent the collar from curling. CN202907865U discloses that a long strip-shaped accommodating cavity is provided at each end of the knitted collar body, and a long strip-shaped support block is provided in the accommodating cavity to prevent the collar from curling. By reasonably setting the position of the accommodating cavity in the collar and setting the length and width of the support block, the support block and the accommodating cavity can be well matched, so that the collar will not curl and maintain a good appearance. CN2790194Y discloses inserting an insert into the hollow space formed by the cylindrical braided structure on both sides of the collar body to keep the edge of the collar straight and the entire collar shape is not easy to curl or deform in a stable state. The above method of inserting the hard insert has the disadvantages of poor appearance uniformity, many processes and complicated wearing.

[0004] In addition, the prior art also solves the curling and wrinkling problems of collars and cuffs by adding a thermal adhesive layer or coating. For example, DE4138578A1 discloses that a heat-fusible mesh sheet such as polyethylene or polyester is connected to a textile material by heating and pressurizing. Although this can improve the shape retention of the collar, the interlayer adhesion of the fabric is poor, stratification is easy to occur, and the air permeability is reduced, and the comfort of the contact part between the collar and the neck is reduced. CN202354380U discloses that a polyurethane coating is coated on the outer surface of the collar body, making it crisp to wear, but the air permeability is poor and it is not suitable for summer wear.

[0005] In summary, it is urgent to develop a fabric with excellent anti-curling performance, uniform appearance, breathable and comfortable, simple preparation, low cost and easy promotion. Summary of the invention

[0006] The purpose of the present invention is to provide an anti-curling fabric and a preparation method thereof. The fabric has the advantages of uniform appearance, breathable and comfortable, excellent anti-curling performance, etc., and the preparation method is simple, low-cost and easy to promote.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, the present invention provides a fabric, comprising the following components: a yarn skeleton and dot-shaped objects; the dot-shaped objects are distributed inside the skeleton or on the non-skin-friendly surface of the fabric, and each dot-shaped object is connected to adjacent yarns in the skeleton.

[0008] The present invention arranges dot-shaped objects inside or on the surface of the yarn skeleton, and utilizes the dot-shaped objects to reinforce the yarn skeleton, thereby improving the overall stiffness of the fabric, and further improving the anti-curling performance of the fabric. At the same time, the dot-shaped objects are dispersed and hidden inside the skeleton or on the non-skin-friendly surface of the fabric, which can not only maintain the air permeability and comfort of the knitted fabric and enhance the wearing experience without affecting the microporous structure of the fabric itself, but also ensure the uniformity of the appearance of the fabric when used in parts such as collars and cuffs.

[0009] The yarn used in the skeleton includes but is not limited to one or more of natural fibers, chemical fibers, and blended yarns or composite yarns thereof.

[0010] The natural fiber is selected from one or more of cotton, wool, silk and linen; The chemical fibers include but are not limited to nylon and / or polyester.

[0011] The dot-shaped objects are composed of low-melting-point fibers; The melting point of the fiber is lower than the melting point of the yarn; The fibers include but are not limited to one or more of spandex, polyester and core-sheath composite polyester filaments.

[0012] In the present invention, cotton yarn, nylon yarn and other yarns are selected to take into account the stability of the yarn skeleton and the air permeability and comfort of the fabric. Low-melting-point fibers are selected as the material of the point-shaped objects. The lower temperature is conducive to heat setting, reducing the difficulty of the process. At the same time, it can also further ensure the comfort and air permeability of the fabric and enhance the wearing experience.

[0013] In one embodiment of the present invention, the yarn is selected from nylon 66 filaments, and the fiber is selected from low melting point polyester.

[0014] In another embodiment of the present invention, the yarn is selected from 21 S Cotton yarn, 30D spandex, low melting point core-sheath composite polyester filament yarn core layer, the fiber is selected from the low melting point core-sheath composite polyester filament yarn sheath layer.

[0015] In another embodiment of the present invention, the yarn is selected from 21 S Cotton yarn, 21 S Polyester-cotton blended yarn, the fiber is selected from 30D low-melting-point spandex.

[0016] In a second aspect, the present invention provides a method for preparing the above-mentioned knitted fabric, comprising the following steps: weaving yarn and fiber to form a knitted structure in which the fiber is sandwiched between the yarn or the fiber is located under the yarn; heat setting; and obtaining the knitted fabric.

[0017] The heat setting temperature is higher than the melting point of the fiber and lower than the melting point of the yarn, and the heat setting time is not less than 5s.

[0018] In a third aspect, the present invention provides a knitted fabric, which is made from the knitted fabric mentioned above.

[0019] The knitted fabric can be a collar or a cuff. Specifically, the collar or the cuff can be a fully fashioned knitted collar or cuff.

[0020] The fully molded knitted collar or cuff is prepared according to the following operations: on the basis of weaving the main fabric structure of the yarn skeleton yarn and the low-melting-point fiber together, an integrated molding knitting technology is used to make the fabric present the shape of the collar or cuff; and then the fabric is heat-set.

[0021] The one-piece knitting technology mentioned refers to conventional knitting technology in the art, such as needle retraction and expansion, density change, etc.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The fabric provided by the present invention has high anti-curling performance, good air permeability, and uniform appearance, thereby significantly improving comfort. When the fabric is further made into a collar or cuffs, there is no need to go through the processes of cutting holes, inserting inserts, etc., and the preparation process is simple.

[0032] Example 1. Preparation of anti-curling knitted fabric This embodiment provides a preparation method for an anti-curling knitted fabric, wherein the fabric is composed of a yarn skeleton and a dot-shaped object located in the middle of the yarn skeleton.

[0033] The preparation method of the anti-curling knitted fabric comprises the following steps: Step 1: Select 200D / 96F DTY nylon 66 filament as the yarn constituting the yarn skeleton, and select 100D / 36FDTY low melting point polyester (melting point is 180°C) as the fiber constituting the dot-shaped object.

[0034] Step 2: On a double needle bed flat knitting machine, follow the Figure 1 The yarn configuration and weaving are performed as shown in a. Specifically, in a single complete cycle, two nylon 66 filaments are fed into the 1st and 3rd routes respectively to weave the double rib weave yarn skeleton together; one low-melting point polyester is inserted into the 2nd and 4th routes. Therefore, both the front and back sides of the fabric are formed by nylon 66 filaments, and the low-melting point polyester is sandwiched between the front and back coils.

[0035] Step 3: Heat-set the fabric at 200°C for 30 seconds to melt the low-melting-point polyester and form point-bonding between the nylon 66 filament yarn skeletons after solidification. The resulting fabric can be used to make collars and cuffs through simple cutting and sewing.

[0036] Step 4: Fabric performance evaluation.

[0037] The results show that the air permeability of the obtained fabric is 35 mm / s, and after 20 washes in a drum washing machine, the fabric has no curling, and the dots are not visible on the fabric surface, and the appearance is uniform. This shows that through the structural design of the yarn skeleton and the dots, as well as the appropriate combination of yarn and fiber, the air permeability and anti-curling performance of the fabric can be improved, thereby improving the comfort of use.

[0038] Example 2: Preparation of anti-curling fully-formed collar The present embodiment provides an anti-curling fully-formed collar, which includes a yarn skeleton and dot-shaped objects located on the non-skin-friendly surface of the yarn skeleton.

Specifically, in a single complete cycle, a cotton yarn is fed into the first route, which is looped only on the front needle bed to form the front side of the fabric; a low-melting-point core-skin composite polyester filament yarn is fed into the third route, which is looped only on the back needle bed to form the back side of the fabric; a spandex yarn is fed into the second and fourth routes, which is looped between the front and back needle beds to connect the front and back sides of the fabric. Combined with the techniques of needle expansion and contraction, density change, etc., the fabric is directly woven into a collar shape.

[0040] Step 3: The fabric is heat-set at 190°C for 1 minute to fully melt the sheath of the low-melting-point sheath-core composite polyester fiber. After solidification, point bonding is formed between the yarn skeleton formed by the cotton yarn, spandex and the low-melting-point sheath-core composite polyester fiber core layer.

[0041] Step 4: Fabric performance evaluation.

[0042] The results show that the air permeability of the collar fabric is 41mm / s, and the fabric has no curling after 20 washes in a drum washing machine. The dots are only distributed on the reverse side of the fabric (non-skin-friendly side), with no effect on the front side of the fabric, and the appearance is uniform.

[0043] Example 3: Preparation of anti-curling fully molded cuffs The present embodiment provides an anti-curling fully molded cuff, which includes a yarn skeleton and a dot-shaped object located in the middle of the yarn skeleton and on a non-skin-friendly surface.

[0044] The preparation method of the above-mentioned fully molded cuff comprises the following steps: Step 1: Select 21 S Cotton yarn, 21 S Polyester-cotton blended yarn (blending ratio 1:1) is used as the yarn skeleton, and 30D low-melting-point spandex (melting point is 150°C) is used as the dot material.

[0045] Step 2: On a double needle bed flat knitting machine, follow the Figure 1c) to knit the main structure. Specifically, in a single complete cycle, feed 1 cotton yarn into the first route and 1 polyester-cotton blended yarn into the third route to knit the double rib structure yarn skeleton together; feed 1 low-melting-point spandex into the second and fourth routes, and tuck one loop at a time on the back needle bed. Combined with the techniques of needle expansion and contraction, density change, etc., the fabric is directly knitted into the shape of a cuff.

[0046] Step 3: The fabric is heat-set at 180°C for 40 seconds to melt the low-melting-point spandex, and after solidification, point bonding is formed between the yarn skeletons formed by the cotton yarn and the polyester-cotton blended yarn.

[0047] Step 4: Fabric performance evaluation.

[0048] The results show that the air permeability of the cuff fabric is 42mm / s, and the fabric has no curling after 20 washes in a drum washing machine. The dots are only distributed between the front and back of the fabric and on the back (non-skin-friendly side), with no effect on the front of the fabric, and the appearance is uniform.

[0049] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention.
