Abstract
Description
Technical Field
[0001] The utility model relates to a light-proof knitted fabric, belonging to the textile field. Background Art
[0002] The earliest main purpose of making clothes by humans was to cover the body. Due to the emergence of shame, clothes are not only for keeping warm, but also for covering important parts. With the development of clothes to date, various fabrics have emerged. Although some fabrics have good functions and appearances, they go against the original intention of covering the body. White and light-colored lightweight fabrics are still the mainstream in summer, but white and light-colored lightweight fabrics have a fatal defect - light transmission, which fails to achieve the proper body-covering effect of clothes. Therefore, it is necessary to develop a light-proof white fabric. Most of the light-proof fabrics on the market are made of fully delustered polyester fiber (fully delustered polyester), and this fiber can significantly reduce the light transmission of lightweight fabrics due to the addition of a large amount of titanium dioxide. It has a remarkable effect when applied to woven fabrics, but the effect is slightly worse when applied to knitted fabrics because knitted fabrics are made by looping yarns and have more light-transmitting holes in their structure, and are not as dense as woven fabrics. Content of the Utility Model
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a light-proof knitted fabric, enabling knitted fabrics to also have a good light-proof effect.
[0004] The technical solution adopted by the utility model to solve its technical problems is:
[0005] A light-proof knitted fabric, which is a weft knitted fabric, includes cotton yarn ply, fully delustered polyester and elastic yarn. The fully delustered polyester and the elastic yarn form loops synchronously and all the loops are used as the base; part of the cotton yarn ply is the loop-forming points, and the rest form float points on the process back side of the base. The number of the float points is not less than that of the loop-forming points, and the same number of the float points are regularly located between adjacent loop-forming points.
[0006] A knitted fabric is formed by looping yarns and the loops interpenetrate with each other, and inevitably there are voids formed by looping. The fully delustered polyester itself has a certain light-proof effect. In the light-proof knitted fabric provided by this application, the elastic yarn and the fully delustered polyester form loops simultaneously. The elastic yarn tightens the fabric, making the base firm, which can reduce the voids formed by looping. When making clothes, the process back side of this fabric faces outward, and the float formed by the cotton yarn ply has a shielding effect on the voids formed by looping, enabling the knitted fabric to also have a light-proof effect.
[0007] In a preferred embodiment, the elastic yarn is spandex with a denier of more than 70D, which is beneficial to making the base more firm, reducing the unfilled coefficient of the knitted fabric, and further reducing the voids between loops.
[0008] In a more preferred embodiment, the elastic yarn is 105D spandex.
[0009] In a preferred embodiment, the cotton yarn ply is a two-ply yarn, which is more conducive to covering the voids formed by looping.
[0010] In a preferred embodiment, the yarn diameter of the cotton yarn ply is greater than the sum of the loop height of the fully delustered polyester and the yarn diameter of the fully delustered polyester. Here, the loop height refers to the "loop height" in the field of knitting.
[0011] In a preferred embodiment, the yarn diameter of the cotton yarn ply is more than three times the yarn diameter of the fully delustered polyester.
[0012] In a first preferred embodiment, the ratio of the float points to the loop points of the cotton yarn ply is 1:1.
[0013] In a second preferred embodiment, the ratio of the float points to the loop points of the cotton yarn ply is 2:1.
[0014] In a third preferred embodiment, the ratio of the float points to the loop points of the cotton yarn ply is 3:1.
[0015] In a fourth preferred embodiment, the ratio of the float points to the loop points of the cotton yarn ply is 4:1.
[0016] The beneficial effects of the present utility model are as follows: The anti-translucent knitted fabric of the present utility model uses two kinds of yarns to loop simultaneously as the base, so that the voids formed by the base looping are small. The fully delustered polyester itself has a certain anti-translucent effect. At the same time, the elastic yarn is used to tighten the base, making the base compact, and the voids formed by looping are further reduced. Then, the float formed by the cotton yarn ply is used to cover the voids formed by the base looping. Therefore, the knitted fabric can also have a good anti-translucent effect.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.
[0021] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present invention.
[0022] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.
[0023] It should be understood that, on the premise of no conflict, any and all embodiments of the present invention can be combined with the technical features in any other embodiment or multiple other embodiments to obtain additional embodiments. The present invention includes such additional embodiments obtained by combination.
[0024] Unless otherwise specified, all technical terms and scientific terms used herein have the standard meanings in the field to which the claimed subject matter belongs. If there are multiple definitions for a certain term, the definition herein shall prevail.
[0025] In the prior art, white or light-colored thin knitted fabrics are prone to light transmission. Of course, there are also some fabrics on the market that have the ability to prevent light transmission by attaching anti-transparent films or multi-layer stitching, but the manufacturing processes of these fabrics are complicated, the costs are high, and it is difficult to promote them.
[0026] To this end, an embodiment of the present application provides a light-proof knitted fabric, which is a weft knitted fabric and includes cotton yarn ply, full dull polyester, and elastic yarn. The full dull polyester and the elastic yarn are looped synchronously, and the full dull polyester and the elastic yarn are all looped as the base. Part of the cotton yarn ply is the loop-forming point, and the rest forms floating-points on the process back side of the base. The number of floating-points is not less than that of the loop-forming points, and the same number of floating-points are regularly located between adjacent loop-forming points.
[0027] Among them, the loop-forming point refers to the part where the cotton yarn ply forms a loop, and the floating-point represents the part where the cotton yarn ply forms a floating line. If the length of the floating line is directly described in length units such as millimeters, it is difficult to see in the drafting pattern and it is also difficult to reflect the positional relationship of the floating line relative to the loop-forming part. To facilitate the description of the length of the floating line, the present application proposes the terms of loop-forming points and floating-points. The distance between one loop-forming point and one knitting point, and each time the floating line crosses a knitting point, it is one floating-point, so that the length of the floating line can be clearly described. A section of floating line can have multiple consecutive floating-points. For example, if a section of floating line crosses four knitting points, it is said that this section of floating line has four floating-points.
[0028] Embodiment 1
[0029] The fabric structure is a plain-weave structure. Refer to Figure 1 , according to the drawing habits in the art, draw the needle arrangement diagram below the drafting pattern, align the drafting pattern with the needle arrangement diagram in columns, draw the cam diagram on the right side of the needle arrangement diagram, and align the cam diagram with the needle arrangement diagram in rows.
[0030] The drafting pattern is a graph that represents the law of the combination of knitted structural units with artificially defined symbols on small squares. The rows in the drafting pattern are the same as the horizontal distribution of the fabric, and the columns in the drafting pattern are the same as the vertical distribution of the fabric. In the drafting pattern, "×" represents forming a loop on the process front side, that is, one loop-forming point, and the blank represents one floating-point, and the continuous horizontal blank represents a section of floating line.
[0031] The needle arrangement diagram is a method of graphically representing the cross-sectional shape of a knitted fabric according to the knitting order and the working conditions of knitting needles. The needle arrangement diagram not only represents the structural units knitted by each needle, but also shows the configuration and arrangement of the knitting needles.
[0032] On a common weft circular knitting machine, the three basic structural units of a knitted fabric are formed by the action of loop-forming cams, tucking cams, and non-knitting cams on the knitting needles. Therefore, the working conditions of the knitting needles of the weft circular knitting machine and the structure of the fabric can also be represented by the configuration diagram of the cams (cam diagram). This is particularly important when arranging the machine processing technology, and the workers need to adjust the machine according to the needle arrangement diagram and the cam diagram.
[0033] In Figure 1In the design drawing, the first row and the third row simultaneously weave in B yarn and T yarn. According to the design drawing, B yarn and T yarn are woven in synchrony and all form loops; the second row and the fourth row weave in A yarn. According to the design drawing, the ratio of the float points of A yarn to the loop-forming points of A yarn is 1:1.
[0034] In Example 1, A yarn is 40S / 2 pure cotton ply yarn, which is the terry yarn used to form floats; B yarn is 60S full dull polyester, which is the base yarn used for full looping to participate in forming the base; T yarn is 105D spandex, which is the elastic yarn used to provide elasticity and reduce the fabric's unfilled coefficient, and is fed in with B yarn.
[0035] The fabric woven on a weft knitting circular knitting machine according to the above regulations in Example 1 basically has no gaps for light to penetrate, proving that this knitting structure can make the light and thin light-colored knitted fabric have an anti-light-penetration effect. And incidentally, it solves the problem of the soft and sagging and boneless knitted fabric, making the knitted fabric have a similar appearance to the woven fabric, with strong texture, and soft and comfortable touch on a relatively stiff base.
[0036] In this application, full dull polyester and elastic yarn are fed in together to weave a plain stitch to form the base. When worn, the skin contacts the full dull polyester. To weaken the chemical fiber feeling of the fabric and enhance breathability, full dull polyester can preferably be full dull polyester staple fiber yarn. Full dull polyester itself has a strong anti-light-penetration effect. The elastic fiber uses spandex with high stretch performance, with a specification of more than 70D to achieve the effect of a tight base, reduce the unfilled coefficient of the knitted fabric, and narrow the gaps between the loops. The cotton ply yarn forms loops and floats according to a certain pattern. The ratio of the float points to the loop-forming points of the cotton ply yarn can be 1:1, 2:1, 3:1, and 4:1. The floats of the single-sided knitted fabric are exposed at the bottom of the fabric. Using the bottom as the front (when making clothes, the front side of the fabric process faces inward and the process back side faces outward), the floats of the cotton ply yarn cover the gaps formed by the loops on the base of the fabric. Since the width of the float (the width that can cover, equivalent to the wire width, wire diameter) is only the cross-sectional diameter of the float, and the width it needs to cover is the loop height of the full dull polyester staple fiber yarn plus the cross-sectional diameter of the full dull polyester staple fiber yarn, the cross-sectional diameter of the cotton ply yarn must be much larger than the cross-sectional diameter of the full dull polyester staple fiber yarn. The wire diameter of the cotton ply yarn must be more than three times the wire diameter of the full dull polyester to achieve a strong shielding effect. Under the same tex, the cross-sectional area of the ply yarn is equal to the cross-sectional area of the single yarn, but the maximum cross-sectional diameter of the ply yarn is larger than that of the single yarn (√2 times that of the single yarn). Therefore, using ply yarn has a better shielding effect. Or rather, under the condition that other parameters and materials remain unchanged, to obtain the same covering degree, compared with using single yarn for covering, using ply yarn for covering can make the fabric have a lower gram weight, that is, the fabric is lighter and thinner, meeting the requirements of summer clothes.
[0037] Example 2
[0038] Refer to Figure 2, in Figure 2 In the design drawing of Figure 2 , in the first, third, and fifth rows, the B yarn and the T yarn are woven in simultaneously. According to the design drawing, it can be known that the B yarn and the T yarn are woven in synchronously and all form loops; in the second, fourth, and sixth rows, the A yarn is woven in. According to the design drawing, the ratio of the float points of the A yarn to the loop-forming points of the A yarn is 2:1.
[0039] In Example 2, the reverse bottom is used as the face, and the float formed by the non-emergence of the needles on the cloth bottom is used to block the gap in the middle of the loops. Among them, the A yarn is 40S / 2 pure cotton ply yarn, which is the fleece yarn used to form the float; the B yarn is 70S full dull polyester, which is the bottom yarn used for full loop formation to participate in forming the base; the T yarn is 100D spandex, which is the elastic yarn used to provide elasticity and reduce the fabric underfill coefficient, and is fed in together with the B yarn.
[0040] In the embodiment of the present application, two kinds of yarns are looped simultaneously as the base, so that the gaps in the base loops are smaller. The full dull polyester itself has a certain light-blocking effect. At the same time, the elastic yarn is used to tighten the base, making the base tight and further reducing the gaps in the loops. Then, the float formed by the cotton ply yarn is used to block the gaps in the base loops. Therefore, the knitted fabric can also have a good light-blocking effect.
[0041] In the description of this specification, the description with reference to terms such as "one embodiment", "certain embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0042] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
