Influenced by the epidemic situation, people's life style has taken place a lot of changes, and on the one hand, the mode of handling official business at home, study at home is normalized gradually, and the time of people at home is good at in the past far away, and on the other hand, people have reduced crowd's wild, and camping on foot becomes another kind and alleviates pressure, release the mode of soul. Whether in living room or in camping place, whether child or adult, a weaving blanket which can be covered or clasped or hung is a very practical article in the life of free and free nature, and is indispensable.

The woven blanket is not only practical, but also beautiful and decorative. The important point of the woven carpet is different from the common fabric for clothes, the front and back surfaces of the woven carpet can be displayed in the using process, and therefore, the patterns, colors and touch feeling of the front and back surfaces of the fabric are very important.

Most of suede blanket sold in the market at present are made of chemical fiber materials and are printed by a printing process, and the fabric has insufficient air permeability, poor heat retention and insufficient delicate design. In addition, some jacquard woven blankets are made of chemical fibers, cotton fibers and the like, the patterns are delicate, but the surfaces of the jacquard woven blankets are often lack of velvet feeling and are slightly gentle. In addition, in order to present jacquard pattern colors, a plurality of groups of colored yarns are needed, and the fabric is often thick and heavy.

The invention provides a high-end blanket which is thick and light in fabric, attractive in color and pattern on the front side and the back side, decorative and comfortable and soft in hand feeling, and the blanket is the research and development direction of the invention.

Disclosure of Invention

The invention aims to improve a design method of double-sided colors of double-sided fabrics and provides a preparation method of a worsted double-sided jacquard blanket.

In order to achieve the technical effects, the technical scheme of the invention is as follows: a method for preparing a worsted double-faced jacquard blanket comprises the steps of fabric style design, color design, texture design, strip dyeing, spinning, weaving and after finishing.

The fabric style design comprises the design of the composition, tightness, weight and surface fiber state of the fabric.

The method comprises the steps of fabric style design, color design, texture design, strip dyeing, spinning, weaving and after-finishing;

the fabric color design comprises the following steps: s1, pattern analysis, S2 yarn design, S3 basic organization structure planning and S4 double-sided color design.

The S3 basic structure plan is a double-layer core filling structure without surface exchange according to the warp yarns; 1O yarn, 1P yarn and 1Q yarn are taken as a group of yarns, and the three yarns are distributed in the fabric at the positions of one surface layer on the front side, one bottom layer on the back side and the other filling layer in the middle; the surface layer of weft yarns is in an elongated float form, so that the warp yarns are rarely exposed and basically only show the color of the weft yarns.

And the S4 double-sided color design is planned according to the S3 basic organization structure, and by applying the mathematic thinking, the same weft yarn cannot be simultaneously arranged at two or more positions of the front side, the middle side and the back side of the fabric, the colors possibly arranged on the front side and the back side of the fabric are planned, and the colors of the front side and the back side of the fabric are conveniently determined.

The S4 double-sided color design specific method is that the color of the front side of the fabric is determined firstly, and because the color of the fabric is expressed mainly by weft yarns, different cloth surface color effects are presented by different frequencies of weft-wise colored yarns appearing on the surface of the fabric;

reasoning is carried out according to the sudoku theory, and when the color of the front side is determined, the possible colors of the back side can be listed; secondly, performing color planning on the front side and the back side of the pattern to ensure that the colors of the two sides are relatively beautiful, and properly adjusting the colors of the front side and the back side according to the requirement; and after the corresponding colors of the front side and the back side are determined, putting the yarns which do not participate in the color development in the middle layer according to the color planning, so that the yarns do not develop the color.

The weave design comprises the following steps: s1' fabric specification design, S2' pattern processing and S3' weave structure design;

the specification design of the S1' fabric comprises the yarn count, the density, the breadth and the weight of the fabric;

and the S3' weave structure design carries out specific weave structure design according to the plans of S2, S3 and S4.

The weight of the fabric was set at 280g/m ² Within.

The fabric after-finishing comprises the following steps: s1, open washing, S2, drying, S3, shaping, S4, napping, S5, softening and decating.

And S1, in the step of open washing, the washing speed is slowed down to 20 +/-2 m/min, and the washing temperature is increased to 90 +/-5 ℃.

And the S2' drying woolen cloth adopts a lower speed, the temperature is increased to 120 +/-5 ℃ according to 20 +/-2 m/min.

S3, shaping is to flatten the fabric before napping, and the fabric is kept full thickness by adopting a fast speed of 50 +/-2 m/min and a low temperature of 180 +/-5 ℃ and overfeeding of 5 +/-1 percent; the S5' softening and decating process adopts mild low temperature of 150 +/-5 ℃ and overfeeding of 5 +/-1% to keep the thickness of the fabric rich, and adopts a light steaming process of 0.7 bar.

The invention has the advantages and beneficial effects that:

the woolen blanket uses wool fiber as a main raw material, because the wool fiber has 16 percent of official moisture regain and a static air space provided by natural curling, the woolen blanket has incomparable comfort and warmth retention compared with blankets made of other materials, while the worsted double-sided jacquard blanket is formed by interweaving high-count worsted wool yarns, has fine and clean patterns and light texture, and has the square meter weight of less than 280g/m ² After finishing treatment such as napping, the fabric is thick, the suede is full, the color is soft, the touch is soft, and the fabric is light and warm.

The design method has the advantages that the design steps and the method of the jacquard fabric are improved, the sudoku idea is applied in the design of double-sided colors, the design method can effectively plan the colors which may appear on the front and the back of the fabric, has a guiding function on the color determination of the front and the back of the fabric, and further provides a basis for the design of a weave texture. The open washing step of the after-finishing process of the production and processing enables weft yarns of various colors to move up and down and to be distributed in the upper, middle and lower thickness directions of the fabric according to the designed weave pattern rule, and the napping step enables color blocks interwoven by the heterochromatic yarns on the surface of the fabric to be harmonious in color and form a full and soft suede.

Detailed Description

The following further describes embodiments of the present invention with reference to examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1

Fabric requirements, i.e. fabric style design requirements: the subject of the tapestry is "tree Shadow of Trees", and the image is interpreted as: the shadow is a blanket laid on the ground by light and shaped along with objects; the design of the tree shadow carpet is just to keep the light shadow of a piece of forest between the square inches of the woven carpet, and the light shadow has two tones of beige and blue, so that two sides of one woven carpet form different colors, like the tree forest under the alternation of the sun shadow and the moon shadow, and occasionally the bird visits among the tree shadows. The size requirement of the woven blanket is 140cm by 180cm, the functional requirement is mainly used for sofa blanket, and the woven blanket can also be used for outdoor covering and warm keeping, and the woven blanket is required to be light and warm.

In the first scheme, if wool yarns are used in both warp and weft directions, the front and back effects can be shown only by using double-layer or multi-layer weave textures, the light-color part is formed by interweaving light-color warp yarns and light-color weft yarns, the dark-color part is formed by interweaving dark-color warp yarns and dark-color weft yarns, so that at least two groups of dark-color and light-color yarns are used for both the warp yarns and the weft yarns, the patterns are in two tones of beige and blue, and in order to make the pattern level clear, white can be added for blending or emphasizing, three colors are used for at least one direction of the warp yarns and the weft yarns. Such asThe fruit yarn had a weight of about 270g/m, as estimated by 100/2 metric counts for worsted high count yarn, and the fabric had a relaxed tightness 170 for the 2/2 double (filled) weave ² . The scheme has the advantages that the warp and weft yarns of the fabric are balanced, and the structure is stable; the wool can be made into full-woollen blankets, but the high-count wool is expensive. The defects are that the yarn count is high, and the napping after finishing is not easy to generate; when the warp and weft yarns are simultaneously inserted from one surface of the fabric to the other surface, namely the surface and inside exchange positions of the yarns, the surface of the fabric is uneven, and the frequency of the surface and inside exchange of the yarns of each part of the fabric is uneven due to uneven color distribution of the patterns, so that the hand feeling tightness degree of each part of the fabric is greatly different.

And in the second scheme, the polyester filament yarns are used as the warp yarns, the wool yarns are used as the weft yarns, and the polyester filament yarns are very thin, so that a weft triple structure or a double-layer (core filling) structure with warp yarns not exchanged in the surface can be adopted, the color of the surface is mainly expressed by the weft yarns, and the weft wool yarns can be properly spun into yarn counts with slightly larger points to be suitable for a napping process. The weight is also 270g/m, estimated as 80/2 metric count and tension of the weft yarn 185 ² . The scheme has the advantages that the cloth surface is smooth, and the tightness degree of each part of the fabric can be more uniform; the weft yarn count is thicker, the density is higher, the after-treatment is relatively easy to rise, and the covering degree of the warp yarn is also good while the filling power and the heat retention are realized; the cost of the scheme is lower than that of the first scheme, but the defect is that the full-carpet can not be manufactured; the second disadvantage is that the cohesion of the polyester filament is poor, and the fabric careless and weak.

And (3) integrating various factors, and determining to adopt a second scheme: the warp and weft of the fabric are respectively 60% of wool, 40% of polyester and 280g/m of the total component proportion ² The pile faces on the left and right sides are large.

The fabric color design comprises the following steps:

s1: analyzing the pattern;

s2: designing yarns;

s3: planning a basic organization structure;

s4: and (5) designing double-sided colors.

The S1 pattern analysis considers the color requirements of the front side and the back side of the woven carpet, one side expresses day, sunlight shines, light beige is taken as a main color, the other side expresses night, dark blue is taken as a main color, but a moonlight cage is arranged, so white filaments are selected in the warp direction, even if the color of weft yarns is not enough to completely cover the warp yarns, the white warp yarns are not disfigured on the cloth surface, the white and bright sunlight can be highlighted on the light color side, and the silvery glow of moonlight is hidden on the dark color side, as shown in figure 1.

The S2 yarn design is mainly a yarn color design. The color of the fabric is mainly expressed by weft yarns, the weft yarn dyeing is slightly adjusted according to three colors selected by a customer and the integral expression of the fabric, and the O yarns are white and not dyed and adopt the soft natural white of wool; p yarn is camel brown according to PANTONE 16-1305TCX, and is slightly yellow and light for having warm and bright feeling of sunlight; the yarn Q is blue at midnight according to PANTONE 19-4027TCX, the color is darker, and the color is slightly lighter because the color is developed on the front and back sides of the fabric and appears to be more abrupt on the side expressing the day.

The S3 basic structure is a double-layer core filling structure which is designed according to the warp yarn not exchanged in the surface, the upper layer and the lower layer are 8 satins, 1 white O yarn, 1 beige P yarn and 1 blue Q yarn are used as a group of yarns, and the three yarns are distributed in the fabric in the positions that one yarn is on the surface layer of the front side, one yarn is on the bottom layer of the back side, and the other yarn is in the middle core filling layer. The surface layer of weft yarns is in an elongated float form, so that the warp yarns are rarely exposed and basically only show the color of the weft yarns.

And S4, the sudoku concept is applied in the double-sided color design to plan the colors possibly appearing on the front and the back of the fabric, so that the process of obtaining the colors of the front and the back of the attractive fabric is more visual and convenient. The specific method is to determine the color of the front side of the fabric, and because the color of the fabric is mainly expressed by weft yarns, different cloth cover color effects can be expressed by different frequencies of weft colored yarns appearing on the surface of the fabric. The weft yarns are white, rice and blue yarns, and 10 combination modes are provided in total by considering the colors of the three groups of yarns, as shown in figure 2.

Then, the same weft yarn can not be simultaneously present at two or more positions of the front side, the middle side and the back side, reasoning is carried out according to the unique thinking of the numbers, when the color of the front side is determined, the possible color of the back side can be listed, referring to the attached drawing, if one side of the fabric takes the large color block in the figure 3, the other side can only select the color from the corresponding small color blocks below the large color block, wherein the color of the condition of 1 white +1 blue +1 meter is not considered because the color is too fancy and unavailable.

Then, the colors of both sides of the pattern are planned, so that the colors of both sides are beautiful, the colors of both sides can be properly adjusted according to the needs, as long as the colors can be found in pairs on both sides in fig. 3, and in the light and shadow pattern of the present embodiment, the final planning result is shown in fig. 4.

The weft yarns are arranged according to 1O1P1Q, the O yarns are white, the P yarns are beige, the Q yarns are blue, each group of weft yarns is considered as a color unit, some color blocks need multiple groups of color units for expression, and if the color block 3 needs 3 groups of yarns to complete a color cycle, the total number of the yarns is 9. In fig. 4, the front and back colors are specified, and according to the color scheme, the yarn that does not participate in the color development is placed in the middle layer, so that the yarn does not develop the color. The weft yarns are arranged according to 1O1P1Q, and the color arrangement and the corresponding yarns of the finally designed weft yarns of each color block are shown in a table 1.

TABLE 1 distribution position of weft in each color patch

The fabric weave design includes the following steps:

s1': designing the specification of the fabric;

s2', pattern processing;

s3': and (5) designing a weave structure.

The specification design of the S1' fabric is to determine specific process parameters of the fabric, such as yarn count, density, breadth, weight and the like, and the specific process parameters are shown in a table 2.

Table 2 technological specification design table

The S2' pattern process determines and adjusts the pattern size according to the required pattern size of the fabric and the fabric density specification, the installation specification, etc., each pixel of the pattern represents a weave point, taking the example as an example, the weaving carpet size is 140cm 180cm, the finished product density is 642 pieces/10 cm, and the weft density is 795 pieces/10 cm, so that the complete weaving carpet needs 8988 warp yarns to interweave with 14310 weft yarns, the pattern size is 8988 pieces 14310 pixels, and then the pattern size is 9104 pieces 14496 pixels according to the weaving machine installation specification, the weaving carpet edge, etc.

And the S3' weave texture design carries out specific weave texture design according to the plans of S2, S3 and S4. The double-layer weave of 16 pieces is designed by considering the tightness degree and the hand feeling requirement of the fabric. The warp yarns are consistent, so that the woolen surface is flat and the hand feeling is uniform, the warp yarns are not changed from an upper layer to a lower layer, the odd warp yarns are interwoven with the weft yarns at the upper layer, the even warp yarns are interwoven with the weft yarns at the lower layer, the unit is interwoven with two warp yarns of 8 warp yarns at the upper layer and the lower layer respectively, in order to display the weft yarns on the woolen surface as much as possible, the front surface and the back surface are interwoven in a satin mode by adopting a 1-to-7-weft surface structure, the weaving is carried out according to 8 pieces of 5 yarns, and the unit is interwoven with 8 weft yarns of 8 weft yarns at the upper layer, the middle layer and the lower layer respectively. When the texture of each patch is designed, the interlacing of the weft yarns with the upper and lower layers is performed according to table 2. Wherein 1, 2, 6 color blocks can complete a color cycle by 1 group of 3 weft yarns, so the basic structure size is 16 x 24, and 3, 4, 5 color blocks complete a color cycle by 3 groups of 9 weft yarns, so the basic structure size is 16 x 72, and the corresponding weave structure of each color block is shown in figure 5.

The fabric after-finishing comprises the following steps:

s1': open washing;

s2': the drying of the woolen cloth is carried out,

s3': shaping;

and S4': napping;

s5': soft, decating.

In the step S1, open-width washing is adopted, the washing speed is reduced to 20m/min, the washing temperature is increased to 90 ℃, grease impurities and the like in the fabric are fully removed, yarns are distributed in the thickness direction of the fabric, and yarns with various colors are movably distributed in the upper, middle and lower three layers of the fabric according to the set direction of the weave texture, so that the color requirement is met, and the fabric is plump.

In the S2' drying process, because the fabric is thick, the drying speed is low, the temperature is increased to 120 ℃ according to 20m/min, and the fabric is fully dried and keeps mild hand feeling.

And S3, in the shaping process, shaping is needed before napping to enable the fabric to be flat, the color change of wool is reduced by adopting a higher speed (50 m/min) and a lower temperature (180 ℃), and the fabric is kept to be thick by 5% of overfeeding.

S4, the napping process is an important process for making a full and thick woolen feeling, because the fabric uses worsted 80Nm/2 high count wool yarns, the fabric structure is loose, warp yarns are polyester filament yarns with weak cohesive force, force control needs to be paid attention to when napping, needling cannot be inserted too deeply into the fabric surface, otherwise yarn slippage is easily caused, napping is carried out on the front and back surfaces of the fabric for multiple times, the force is adjusted according to actual conditions in each napping time, napping enables the color block colors interwoven by the heterochromatic yarns on the surface of the fabric to be harmonious, and the napping surface is full and soft, so that the attractiveness, the full and thick feeling and the light weight of the blanket fabric are realized.

The S5' softening and decating process is the last process before the finished product is finished, the soft setting is carried out after napping, the hand feeling can be further improved, the fabric is still kept to be thick by adopting mild low temperature of 150 ℃ and 5% overfeeding, and a light steaming process of 0.7bar is adopted.

The dyeing and finishing process flow comprises the steps of grey cloth → open washing → drying woolen cloth → middle inspection (inspecting the surface condition of woolen cloth) → finishing (trimming grass scraps and repairing the defects of the front path) → sizing → napping → softening → decating, the equipment and process parameters used in the dyeing and finishing process are shown in a table 3

In addition:

the production process of the worsted double-faced jacquard blanket comprises the aspects of strip dyeing, compound combing, spinning, weaving, after finishing and product packaging.

Strip dyeing process: dyeing → backwashing → wool making → sliver mixing → front gill → combing → back gill

The spinning process comprises the following steps: mixing → gilling → roving → spun yarn → spooling → doubling → two-for-one twisting → steamed yarn

Weaving flow: warping → drafting → weaving → blank detection → raw repair

The weaving of the worsted double-faced jacquard blanket is carried out on a jacquard machine, and the blanket is used as a blanket, so the border form of the blanket is considered in the weaving pattern, the weaving process and the like.

If the fringe is to be used as warp or weft yarns at the edge of the carpet, the width of the fringe is taken into account when designing the woven texture, and the yarns used at the fringe and the weave used take into account the following aspects: 1. the yarn to be drawn out finally at the tassel is cheap yarn so as to save cost and consider that the yarn is easy to draw out of the fabric; 2. the tassel position and the fabric main body position are kept flat and consistent in shrinkage, and the problems of cloth cover deflection and wrinkling caused by shrinkage difference cannot occur particularly in after finishing; 3. if tassels are woven into small strands, the texture at the tassels is favorable for facilitating the strand-dividing thread taking of knitting workers.

If the edges of the blankets are cut and then are overlooked, edge-covered and other forms are made, the upper machine organization chart does not need to be additionally designed for the edges, but the complete pattern is considered to be in an effective cutting range, the sizes of the cloth edges and the cloth body are integrally considered, and the open lines are used as boundary lines among blankets to facilitate cutting. In this example, a trimming and overlocking process is used.

The finished blanket is measured in terms of complete number, and in order to reduce waste, the length of the blanket is set to be an integer multiple of the length of the blanket plus 1 meter, namely, 50cm are beaten on the head and tail respectively, so that the complete blanket cannot be damaged in the subsequent procedures such as sewing.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the technical principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
