Description
Technical Field
The invention relates to a preparation method of a fabric and a product thereof, in particular to a high-shielding fabric, a preparation method and application thereof in preparing advertising cloth.
Background
The fabric used as the advertising cloth generally needs to be subjected to coating treatment on the surface to enhance the shielding property and the light transmission uniformity of the fabric, but the coating inevitably causes pollution to the environment and is poor in environmental protection property. The fabric is not subjected to coating treatment, and when the fabric is used for advertising cloth, the problem of light leakage of star points can be caused by lighting on the back surface of the fabric, so that the problem can be avoided only by using the fabric with high shielding property. The visual shielding property of the fabric depends on the absorption and reflection characteristics of the ambient light source and the fabric to the light wave, and the fabric structure determines the absorption and reflection of the fabric to the light wave as an internal reason for influencing the shielding property of the fabric. How to produce the high-shielding fabric through proper weaving steps does not provide a good method in the prior art.
Disclosure of Invention
The invention aims to provide a preparation method of a high-shielding fabric, which aims to solve the problems in the background art.
The invention also aims to provide a high-shielding fabric, which solves the technical defects that the advertising cloth fabric in the prior art needs to be subjected to coating treatment and has low environmental protection performance, and the existing fabric is insufficient in shielding performance when used as advertising cloth.
The technical scheme adopted by the invention for solving the technical problems is as follows:
a preparation method of a high-shielding fabric comprises the following process steps:
(1) selecting yarns: selecting the polyester elastic yarns with the fineness range of 15D-50D and the polyester filament yarns with the fineness range of 15D-50D as yarns;
(2) warp knitting: the warp knitting machine is knitted by adopting three guide bars, the threading modes of the three guide bars are full threading, the laying mode of the three guide bars is in the same direction, the first guide bar and the second guide bar adopt the polyester elastic yarns, the first guide bar and the second guide bar adopt the variable warp plain weave structure for knitting, the third guide bar adopts the polyester filaments, and the third guide bar adopts the chain knitting fabric structure for knitting;
(3) overflow dyeing: adopting a direct grey cloth dyeing process on an overflow dyeing machine;
(4) and (3) after finishing: and (5) tentering and shaping on a shaping machine.
The inventors limited the fineness of the yarn to the range of 15D to 50D, mainly for the following reasons:
1. gram weight: under the condition that other process conditions are the same, the thicker the yarn is, the thicker and firmer the fabric is, and the heavier the gram weight is, so that the cost is increased, and the product selling price is improved; a more important drawback is that the stiffness of the fabric increases and the wrinkle resistance of the fabric decreases, which is very detrimental to the end use of the product;
2. the thicker the yarn, the larger the required warp feeding amount of the yarn during weaving, the larger the loops formed by the yarn in the fabric, and the larger the large loops, the larger the pores in the loops, which can cause the reduction of the fabric shielding property;
3. if the yarn is too thin, the fabric is too light and thin, and the shielding property is insufficient;
4. the yarn range is set within 15D-50D, the gram weight of the fabric is mainly controlled to be 200-300gsm, the economic performance of the fabric is considered, and various performances required by the advertising fabric are considered.
Preferably, the fineness of the yarn is in the range of 20D-50D.
Preferably, the yarn selection comprises a first guide bar and a second guide bar which are made of 15D-50D/6F-144F polyester elastic yarns, and a third guide bar which is made of 15D-50D/1F-144F polyester filaments.

The optimal scheme is that 30D/36F polyester stretch yarns and 30D/72F polyester filaments are selected as yarns.
Definition of number of filaments in yarn selection:
1. the number of monofilaments (unit F) has great influence on the shielding performance of the fabric, and under the same fineness, the more the number of the monofilaments is, the better the dispersion and tiling performance of the monofilaments in the yarn on the surface of the fabric is, and the better the smoothness of the surface of the fabric is; the higher the fabric surface white finish; the key point is that the monofilament can effectively help to cover gaps among extension lines of the fabric, and the fabric can be ensured to have excellent shielding performance by combining with larger longitudinal coil density;
2. however, the more the number of the monofilaments is, the lower the weaving performance of the yarn in warp knitting because the number of the monofilaments is easy to disperse; broken filaments are easily generated during warping, and the broken yarn probability during weaving can be increased due to the warped broken filaments; in addition, if the monofilaments are easy to scatter during weaving, some monofilaments cannot be fed into a needle hook to cause yarn breakage.
3. The more filaments, the higher the price of the yarn.

Detailed Description
The technical solution of the present invention is further specifically described below by way of specific examples in conjunction with the accompanying drawings. It is to be understood that the practice of the invention is not limited to the following examples, and that any variations and/or modifications may be made thereto without departing from the scope of the invention.
In the present invention, all parts and percentages are by weight, unless otherwise specified, and the equipment and materials used are commercially available or commonly used in the art. The methods in the following examples are conventional in the art unless otherwise specified. The components or devices in the following examples are, unless otherwise specified, standard parts or parts known to those skilled in the art, the structure and principle of which are known to those skilled in the art through technical manuals or through routine experimentation.
The invention provides a preparation method of a high-shielding fabric, which comprises the following process steps:
(1) selecting yarns: selecting polyester elastic yarns with the fineness range of 20D-50D and polyester filament yarns with the fineness range of 20D-50D as yarns;
(2) warp knitting: the warp knitting machine is knitted by adopting three guide bars, the threading modes of the three guide bars are full threading, the laying mode of the three guide bars is in the same direction, the first guide bar and the second guide bar adopt the polyester elastic yarns, the first guide bar and the second guide bar adopt the variable warp plain weave structure for knitting, the third guide bar adopts the polyester filaments, and the third guide bar adopts the chain knitting fabric structure for knitting;
(3) overflow dyeing: adopting a direct grey cloth dyeing process on an overflow dyeing machine;
(4) and (3) after finishing: and (5) tentering and shaping on a shaping machine.
In the invention, the yarn is preferably selected from 30D/36F polyester stretch yarn and 30D/72F polyester filament yarn. The 30D/36F polyester elastic yarns are used as the yarns of the first guide bar and the second guide bar, so that the yarns can be flatly laid on the surface of the fabric, the smoothness of the surface of the fabric is effectively improved, gaps in the fabric are covered as much as possible, and the shielding performance of the fabric is improved. The 30D/72F polyester filament is used as the yarn for the third guide bar, and because the polyester filament is higher than the boiling water shrinkage of the polyester elastic yarn, the yarn of the third guide bar shrinks and becomes shorter due to the high boiling water shrinkage in the subsequent overflow dyeing step, and because the third guide bar is woven by adopting a chain stitch structure, the shrinkage of the fabric in the longitudinal direction is large, the coil density of the fabric in the longitudinal direction can be greatly increased, so that the high-density fabric is obtained, and the excellent shielding performance is achieved.
In the warp knitting weaving, the first guide bar and the second guide bar are woven by adopting a variable warp plain weave structure, the extending line in the weaving structure is longer, the longer the extending line is, the smaller the included angle between the extending line and the horizontal line is, the closer the yarn is to the horizontally placed straight line, and after the woven fabric surface is subjected to subsequent sizing, the fabric surface is flat and smooth, and the effect similar to a mirror surface is obtained.
In the warp knitting structure, the third guide bar is knitted by adopting a chain stitch structure, and the third guide bar can adopt an open chain stitch structure or a closed chain stitch structure. The transverse and longitudinal rows of the chain knitting weave are not connected with each other by extension lines, and the polyester filament yarns are selected by matching with the yarns, so that the longitudinal density of the fabric can be increased by generating shrinkage in the longitudinal direction of the fabric during weaving.
In the invention, in the warp knitting weaving, the yarn laying mode of the three guide bars is the same-direction yarn laying, so that the fabric has higher longitudinal density. The principle is as follows: the structure of the three-comb equidirectional lapping yarn is obviously different from the three-comb reverse lapping yarn in coil form, the reverse lapping yarn basically balances the left and right tension of the coil by the extension line due to the different directions of the extension line, and the coil in the longitudinal row of the coil of the structure is vertical; all extension lines of a first transverse row of the structure of the equidirectional lapping yarn are leftward, the extension lines can provide leftward pulling force for the coil, a right loop post of the coil starts to shrink and shorten after being pulled, and the coil can incline rightward; the extension line of the second row can provide a right pulling force for the coil, the left loop column of the coil of the second row is shortened in pulling force, and the coil can incline to the left; that is, in such a configuration where the first course is inclined to the left and the second course is inclined to the right, the coil inclination results in a greater longitudinal density.
In the overflow dyeing, the direct dyeing process of the gray cloth is adopted, so that the gray cloth is retracted as much as possible in the longitudinal direction and the transverse direction of the fabric in the overflow dyeing machine, and the larger longitudinal density of the fabric is obtained. The specific method of the direct dyeing process of the gray cloth is not particularly limited, and the technical scheme of direct dyeing of the gray cloth, which is well known to those skilled in the art, is adopted.
In the invention, in the post-finishing, the fabric is transversely stentered and shaped as much as possible, meanwhile, overfeeding is added to increase longitudinal density, so that yarns in the fabric are straightened, and extension lines are basically horizontal, thereby obtaining a smooth surface effect.
In the invention, in order to obtain better fabric flame retardant effect, the after finishing can further comprise the following steps:
(4a) and (3) flame-retardant finishing: and (3) soaking the fabric into a flame retardant solution, padding and drying.
The purpose of the flame-retardant finishing is to ensure that the fabric has a high standard of flame-retardant performance. The invention has no special limitation on the specific method of flame-retardant finishing, and the technical scheme of flame-retardant finishing in fabric processing, which is well known by the technical personnel in the field, can be adopted.
In the present invention, no better textile printing effect is obtained, and the after-finishing may further comprise the following steps:
(4b) and (6) performing infiltration finishing.
The purpose of the penetration finishing is to improve the color absorption performance and the penetration performance of the fabric to the printing paste and ensure that the fabric has excellent printing effect. The invention has no special limitation on the specific method of the penetration finishing, and the technical scheme of the penetration finishing in the fabric processing, which is well known by the technical personnel in the field, can be adopted.
The invention provides a high-shielding fabric which is prepared according to the method. And (3) carrying out transmissivity and reflectivity tests on the fabric, calculating that the shielding rate of the fabric reaches more than 70%, and having higher shielding property. And (3) carrying out flame retardant test on the fabric, wherein the burning time of the droppings is less than or equal to 2 seconds, the weight loss rate is less than or equal to 40 percent, and the flame retardant test result is qualified.

The 9 groups of high-shielding fabrics prepared in the above examples were subjected to technical index tests, and the test results are shown in table 2.
Table 2 detection data of high-shielding fabric
Example 11 a finer polyester was used: 20D/48F polyester stretch yarns and 20D/12F polyester filament yarns, and developing a light-gram-weight advertising fabric with square meter of 150 gs; at the same time, the adjustment is made on the organization: thirdly, changing the organization of the guide bar into a chaining organization to compare the compactness of the fabric; from the test results, the appearance of the fabric is smooth and clean and meets the design requirements under the condition that 20D polyester yarns are used and the number of monofilaments and the weave structure are different; the fabric has compact coils and a shielding rate of 66 percent, and completely meets the requirement of the advertising fabric (the shielding rate is more than or equal to 54 percent).
The yarn of example 12 is the same as example 11, but with an adjustment in the weave structure of the fabric: shortening the length of the extension line of GB2 by one needle pitch from 1-0/4-5// to 1-0/3-4/; at the same time, the organizational structure of GB3 is changed back to the port chaining: 1-0/0-1//, to verify variations in cloth cover, grammage and masking properties; from the test result, the gram weight of the fabric is lightened, the appearance of the cloth cover is smooth and clean, the shielding rate is 66%, and the use requirement is met without reduction.
Example 13 is based on example 11 with the weave structure being kept unchanged and the coarser polyester yarn being replaced: GB1 and GB2 use P50D/144F polyester elastic yarns, GB3 uses P50D/24F polyester filaments, the yarn fineness becomes thicker, the number of monofilaments is increased, and the purpose is to develop thick and high-shielding advertising fabrics; from the test results, the surface smoothness of the fabric is slightly reduced due to the fact that the yarn fineness is thickened and the number of the monofilaments is increased, but the gram weight of the fabric is obviously increased (315gsm), the shading rate is obviously improved (79%), and the fabric meets the use requirements.
Example 14 is based on example 13 with the following modifications: the extension line of GB2 shortens 2 stitches to verify the effect of short extension lines on fabric shading; meanwhile, the yarns of GB3 are changed into P30D/72F, so that the thin yarns are used for increasing the longitudinal retraction of the fabric in dyeing, and the longitudinal density of the fabric is increased to increase the shielding property of the fabric. From the test result, the extension line of GB2 is shortened by 2 needles, and the influence on the fabric shielding performance is not obvious; however, the fineness of the GB3 yarn is fine, so that the yarn has great influence on the physical properties of the fabric: the gram weight of the fabric is changed to 357 gsm; meanwhile, the shielding rate is slightly increased to 82%, and the shielding performance index is very excellent and far exceeds the requirement of the advertising fabric (the shielding rate is more than or equal to 54%). Of course, the higher the shielding performance, the better the shielding performance corresponding to the advertising fabric.
In example 15, we tested a completely new structure: the method is characterized in that the yarn padding number of GB1 is adjusted from 1-0/4-5// to 1-0/3-4//, namely, a GB1 extension line is shortened by one stitch, and meanwhile, the yarn padding number of GB2DE is also adjusted to 1-0/3-4//, so that the purpose of verifying the appearance change and the change of the shielding performance of the fabric is achieved; from the test results, due to the shortening of the extension line, the smoothness of the fabric is slightly improved, the shielding performance is good, and other physical indexes meet the use requirements.
Example 16 was a yarn change on the weave structure of example 15, the yarn being changed to: GB1& GB2 use P20D/48F polyester elastic yarn, GB3 chooses P20D/1F, the purpose is to verify the influence of the fabric performance of adopting thinner yarn pairs under the organizational structure; from the test results: the fabric has compact, flat and smooth appearance; the shading (66%) is still satisfactory at a lighter fabric grammage (147 gsm). However, as the fineness of the yarn decreases, the fabric becomes lighter and thinner, and the shielding performance also decreases to a certain extent.
Example 17 tests a new weave structure, compared with example 16, the lapping yarn of GB1 is not changed and is still 1-0/3-4//, but the lapping yarn of GB2 shortens one needle and is 1-0/2-3//, meanwhile, the yarns of GB1& GB2 adopt P50D/144F polyester stretch yarns, and GB3 adopts 40D/24F polyester filaments, so as to test the influence of the new fabric structure on the fabric performance; from the test result, as the fineness of the GB1 and GB2 yarns becomes thicker, the number of monofilaments is increased, the surface smoothness of the fabric is reduced to a certain extent, but the fabric meets the use requirement, the gram weight of the fabric is increased (319gsm), the shielding rate of the fabric is good (79%), and other physical indexes meet the use requirement of the fabric.
Example 18 exactly the same weave construction as in example 17 was used, but with a change in the yarn: keeping the yarns of GB1 unchanged, replacing the yarns of GB2 with P30/36F polyester elastic yarns and replacing the yarns of GB3 with P30D/72F polyester filaments, aiming at reducing the weight of the fabric and obtaining more economic price; from the test results, the appearance of the fabric was similar to that of example 17, indicating that the appearance of the fabric was more affected by the GB1 yarn; the grammage of the silk fabric is significantly reduced from that of example 17 to 255 gsm; the shielding rate is slightly reduced to 75 percent and is still good, and other physical indexes meet the use requirements of the fabric.
Example 19 the exact same weave construction as in example 11 was used, but with the yarn replaced: the yarns of GB1 and GB2 are changed into 20/12 semi-smooth elastic yarns, the fineness is not changed, but the number of monofilaments is reduced; meanwhile, the yarns of GB3 are replaced by P50D/144 filaments, the fineness of the yarns becomes thicker, the number of the filaments is increased at the same time, and the weight of the fabric is slightly increased while the economic performance is considered, so that better shielding performance is obtained; from the test result, the appearance of the fabric is smoother and smoother than that of the fabric in example 3, which shows that the thickness of the GB3 yarn also has influence on the appearance of the fabric, the bottom comb of the yarn is thicker, and the yarn has better supporting effect on the cloth surface, so that the cloth surface is smoother; the grammage of the fabric was increased by 42gsm to 193gsm compared to example 11; the shielding performance is slightly improved to 68 percent, and other physical indexes meet the use requirement of the fabric.
The fineness of the yarns used in examples 1-19 varied from 20D to 50D, the number of monofilaments varied from 1F to 144F, and different fabric constructions were tested in each example; the test results of these examples demonstrate that: the yarn fineness is within the range of 20D-50D, the monofilament number is within the range of 1F-144F, and the advertising fabric with different gram weights, different styles and high shielding performance can be designed and produced.
The fineness of the yarn of example 1 is 30D, the gram weight of the product is 243gsm, and the shielding rate is 71%; while the yarn fineness of example 11 was 20D, the product grammage was 151gsm, and the shading rate was 66%, comparing the test results of example 1 and example 11 found that: as the yarn becomes finer, the grammage of the fabric becomes lighter, and although the fabric's masking property is slightly reduced, the change is not large. From this, we conclude that on the basis of example 11, if the yarn fineness is changed from 20D to 15D, satisfactory shading performance can still be obtained, only the grammage of the fabric is reduced, and therefore the yarn fineness of 15D still meets the requirements of the present invention, and the object of the present invention can be achieved.
