Advantageous effects

1. The invention provides a fabric with a self-adjusting structure, which is a fabric with a structure which is continuously self-adjusted due to the designed structure in the processing process and finally achieves the designed structure. The invention sets a single repeating unit to comprise a first structural area and a fourth structural area which are diagonally arranged, a second structural area and a third structural area which are diagonally arranged, and breakpoint cushion wefts arranged in the structural areas. The adjacent repeating units are connected to form a pocket-like structure with the center as a fourth structural area, four corners as a first structural area and four edges as a second structural area and a third structural area. The first structure area and the fourth structure area are double-layer structures, and the second structure area and the third structure area are single-layer structures. As shown in fig. 7, since the second and third structural regions are single-layer structures, the number of warp yarns in the second structural region is the same as that of the fourth structural region, and the number of weft yarns is the same as that of the first structural region; the number of warp yarns in the third structural area is the same as that of the warp yarns in the first structural area, and the number of weft yarns is the same as that of the weft yarns in the fourth structural area. The warp and weft yarns of the second and third structural regions have a high tightness with respect to each other, and the warp and weft yarns of the first and fourth structural regions have a low tightness with respect to each other. The warp and weft yarns of the second structure area with high tightness are in a contraction trend due to the buckling action, the warp yarns of the fourth structure area are respectively drawn in the second structure area along the warp direction, and the weft yarns of the first structure area are drawn in the second structure area along the weft direction; due to the buckling effect, the third structural area yarns with high tightness draw the warp yarns of the first structural area into the third structural area along the warp direction and draw the weft yarns of the fourth structural area into the third structural area along the weft direction respectively (the arrows in fig. 7 indicate the directions of the forces). The yarns in the second structure area and the third structure area draft the yarns in the first structure area and the fourth structure area towards the second structure area and the third structure area, and the first structure area and the fourth structure area perform self-adjustment on the structures of the second structure area and the third structure area connected with the first structure area and the fourth structure area, so that the tightening effect is realized. Because the weft yarn is arranged in the first structure area and the fourth structure area, the two areas have obvious bulges after being tightened.

The break point pad weft comprises a first yarn section without polyester filaments and a second yarn section with the polyester filaments which are alternately distributed; by utilizing the water-soluble characteristic of the vinylon filament, after the fabric is subjected to a dyeing process, the continuous water-soluble vinylon filament in the weft of the breakpoint mat is dissolved, the structure of the first yarn section is damaged and disintegrated, and the structure of the second yarn section is not disintegrated due to the dissolution of the water-soluble vinylon filament under the action of the polyester filament. Meanwhile, in the weaving process, the first yarn section of the double-layer structure area is disintegrated, the short fiber roving is untwisted and dispersed in the double-layer structure, so that loose fibers are filled in the first structure area and the fourth structure area, the loose fibers are fluffy and convex, and the self-adjusting function is realized by matching with the fabric structure, so that the fabric presents a locally convex three-dimensional rectangular array arrangement structure, the convex effect can be generated on the surface of the fabric, and the local contact is realized, but not the plane full contact; the single-layer structure can better resist the bulge effect, the adjacent single-layer structure areas can form a functional continuous conduction channel, and the four structure areas have a synergistic effect, so that the functional characteristics of the fabric are better promoted. Meanwhile, the second yarn section of the break point pad weft yarn is protected by the polyester filament yarn, and the second yarn section participates in the forming of the fabric structure of the single-layer structure area in the form of yarn, so that the stability of the fabric structure of the single-layer structure area is improved, and the problem of unstable structure caused by the dissolution of water-soluble vinylon is solved.

3. The area size ratio of the first structural area, the second structural area, the third structural area and the fourth structural area can be adjusted according to needs, the tissue structure is flexible and variable, and the adjustment range is wide. The second structure area and the third structure area which form the single-layer structure area are connected with the first structure area and the fourth structure area which are adjacently arranged, the double-layer structure area and the single-layer structure area are adjacently arranged and diagonally connected, and the single-layer structure area is broken and the weft yarn is used for protecting the structure.

and S13, determining the yarn arrangement ratios of the first structure area, the second structure area, the third structure area and the fourth structure area. Those skilled in the art should understand that in the first structural area and the fourth structural area, the ratio of the surface warp yarns to the inner warp yarns may be one of 1:1, 2:1 and 2:2, or may be other ratios, and may be set according to the product design requirements, which is not limited specifically; the ratio of the top weft yarns to the bottom weft yarns may be one of 1:1, 2:1 and 2:2, or may be other ratios, and may be set according to product design requirements, and is not particularly limited.

Referring to fig. 6, in step S2, the breakpoint mat weft includes a staple roving, a water-soluble vinylon filament 1 continuously wrapped around the staple roving, and a polyester filament 2 discontinuously wrapped around the staple roving to form a first yarn segment a and a second yarn segment b alternately distributed. In the break point pad weft yarns, the water-soluble vinylon filaments 1 are continuous filaments, and the polyester filaments 2 are arranged at intervals. Width W in weft direction according to first structural region A_AWidth W in weft direction of second structural region B_BDetermines the ratio of the first yarn section a to the second yarn section b of the break point pad weft yarn. In particular, in said first structural zone a, the length L of said first yarn section a_aWidth W in weft direction from the first structure area A_AKeeping consistent; in the fourth structural zone D, the length L of the first yarn section a_aAlong the weftThe direction is consistent with the latitudinal width of the fourth structural region D; in the second structural area B, the length L of the second yarn section B_bWidth W in weft direction with respect to the second structural zone B_BKeeping consistent; the length L of the second yarn section b in the third structural area C_bIn the weft direction, to the width of the third structural zone C.

The method does not need to specially increase working procedures, only needs to adjust process conditions, does not increase process flows, and is beneficial to controlling cost.

According to the arrangement, at the position of the double-layer structure, the break point pad weft yarns are padded into the two layers of fabrics in a mode that the water-soluble vinylon filament yarns 1 are wrapped with the staple fiber roving yarns, and compared with the traditional functional yarns, the break point pad weft yarns are exposed on the surfaces of the fabrics in a mode of tissue points, the requirements on spinnability and weavability of the pad weft yarns are effectively reduced, the application range is wide, fibers which cannot be used in the traditional process and have poor spinnability can be used, and the regeneration of waste raw materials is realized; the defects that the appearance, the hand feeling, the wearing comfort and the like of the fabric are influenced by filling weft yarns in the traditional process are avoided, the abrasion of functional yarns is effectively reduced, and the service life of the fabric is prolonged; in addition, the filling weft yarn is filled between the double-layer tissues, so that the water washing resistance of the fabric is improved. In addition, the functional yarn in the break point pad weft is interwoven in the fabric in a single-layer structure area in a yarn form, so that the stability of the fabric is improved, and the problem of functional fiber exposure caused by fiber untwisting is avoided.

The following describes the self-adjusting fabric with different structures provided by the present invention with reference to the first to fourth embodiments:

example one

A preparation method of a self-adjusting functional wall cloth fabric comprises the following steps:

s1, determining that the surface and inner tissues of the first structural area A and the fourth structural area D both adopt plain tissues to form double-layer tissues; the second structure area B and the third structure area C are both textured into a single-layer structure by adopting two upper and two lower twill groups; determining the ratio of the latitudinal width of the first structural region to the latitudinal width of the second structural region as W_A:W_B＝1：4；

S2, determining the materials of the warp yarns and the weft yarns of the first structural area A, the second structural area B, the third structural area C and the fourth structural area D and the break point pad weft yarns (shown in Table 1); according to table 1, the break point pad weft yarn consists of kapok roving, water-soluble vinylon filaments 1 continuously wrapped outside the kapok roving and polyester filaments 2 discontinuously wrapped outside the kapok roving;

s3, weaving after drawing in and denting according to the upper machine drawing (shown in figure 2);

in the first structural area A and the fourth structural area D, the break point pad weft yarns do not participate in interweaving and are only padded between two layers of tissues of the double-layer tissue structure; in the second structural area B and the third structural area C, the break point pad weft yarn participates in interweaving;

s4, after weaving, refining the fabric, wherein the temperature is higher than 85 ℃, washing the fabric, dyeing the fabric after washing, and dyeing the fabric by adopting an overflow jet dyeing machine, wherein the fabric is subjected to external force impact during dyeing, so that the broken point pad weft yarns in the first structural area A and the fourth structural area D are untwisted, uniformly dispersed and filled in the double-layer structural area to form bulges; in the second structural area B and the third structural area C, because the polyester filament 2 is insoluble in water, the break point pad weft yarn still keeps the yarn structure and participates in interweaving, and the self-adjusting fabric with the concave-convex structure is obtained.

In the weaving process, when four weft yarns are driven, a group of break point pad weft yarns are padded. The weaving process parameters and raw material settings are shown in table 1 below.

Table 1 weave architecture design and weaving process parameter set for example one

Referring to fig. 1, a self-aligning fabric prepared according to an embodiment includes a plurality of repeating units arranged in an array structure. The single repeating unit comprises a first structural area A and a fourth structural area D which are arranged diagonally, and a second structural area B and a third structural area C which are arranged diagonally. The first structural area A and the fourth structural area D are double-layer structures formed by surface tissues and inner tissues and are arranged in a left diagonal manner; the second structural area B and the third structural area C are single-layer tissues and are arranged in a right diagonal manner.

Referring to fig. 7, wherein the arrows indicate the direction of force, since the second and third structural regions B, C are single-layer structures, the number of warp yarns in the second structural region B is the same as the number of warp yarns in the fourth structural region D, and the number of weft yarns is the same as the number of weft yarns in the first structural region a; the number of warp yarns of the third structural area C is consistent with that of the warp yarns of the first structural area A, and the number of weft yarns is consistent with that of the weft yarns of the fourth structural area D. The warp and weft yarns in second and third structural regions B, C have a high degree of tightness with respect to each other and the warp and weft yarns in first and fourth structural regions A, D have a low degree of tightness with respect to each other. The warp and weft yarns of the second structure area B with high tightness are in a contraction trend due to the buckling action, the warp yarns of the fourth structure area D are drawn together towards the second structure area B along the warp direction, and the weft yarns of the first structure area A are drawn together towards the second structure area B along the weft direction; and the third structural area C yarns with high tightness draw the warp yarns of the first structural area A towards the third structural area C along the warp direction and draw the weft yarns of the fourth structural area D towards the third structural area C along the weft direction respectively due to the buckling action. By integrating the interaction relationship between the warp and weft yarns in the single-layer structural area and the double-layer structural area, the yarns in the second structural area B, C and the third structural area B, C draw the yarns in the first structural area A, D and the fourth structural area A, D to the second structural area B, C, and the first structural area A, D and the fourth structural area A, D perform structural self-adjustment on the second structural area B, C and the third structural area B, C connected with the first structural area A, D, so that the tightening effect is realized. The first and fourth structural regions A, D are provided with distinct protrusions when tightened due to the presence of the weft inserted therein. Therefore, the self-adjustment is realized on the fabric structure, on one hand, the weaving difficulty caused by the shrinkage difference of the single-layer and double-layer tissue alternate structure is reduced; meanwhile, the larger buckling of the single-layer tissues (the second structural area B, C and the third structural area B, C) on the peripheral sides assists in locking the double-layer tissues (the first structural area A and the fourth structural area D) in the center, so that the exposure of the weft yarns of the breakpoint mat is prevented. On the other hand, the single-layer weave structure plays a role in stabilizing the whole fabric structure, and the fabric structure is flat and convenient to weave.

The broken point pad weft comprises kapok staple fiber roving, water-soluble vinylon filaments 1 continuously wrapped outside the kapok staple fiber roving and polyester filaments 2 discontinuously wrapped outside the staple fiber roving and the water-soluble vinylon filaments 1 to form a first yarn section a and a second yarn section b which are alternately distributed. The length L of the first yarn section a_aAcross a width W in the weft direction in a first structural region A_AKeeping consistent; the width W in the weft direction of the fourth structural zone D_BAnd the consistency is maintained. The length L of the second yarn section b_bIn aThe width W in the second structural region B in the weft direction_BKeeping consistent; a width W in the weft direction within the third structural zone C and the third structural zone C_AAnd the consistency is maintained. That is, the ratio of the lengths of the first yarn section a and the second yarn section b of the break point inlay weft yarn in the first structural area and the second structural area is L_a:L_b1: 4; in the fourth structural area and the third structural area, the length ratio L of the first yarn section a to the second yarn section b of the break point padding weft yarn_a:L_b4:1, respectively matching the first yarn section and the second yarn section of the break point pad weft yarn with the single-layer and double-layer areas. By joining the left diagonal and right diagonal structural regions, adjacent repeat units are joined to form a pocket-like structure having a center of the fourth structural region, four corners of the first structural region A, and four sides of the second and third structural regions B, C.

The first yarn sections a of the break point padding weft yarn arranged between the surface tissue and the inner tissue of the first structure area A and the fourth structure area D are not interwoven and are only padded between two layers of tissues of the double-layer tissue structure. Compared with the traditional functional yarn which is exposed on the surface of the fabric in the form of the texture points, the arrangement effectively reduces the spinnability and the weavability requirements of the breakpoint mat weft, has wide application range, can use the fiber which cannot be used in the traditional process and has poor spinnability, and realizes the regeneration of waste raw materials; the defects that the breakpoint pad weft affects the appearance, hand feeling, wearing comfort and the like of the fabric in the traditional process are overcome, the abrasion of the functional yarn is effectively reduced, the service life of the fabric is prolonged, and in addition, the breakpoint pad weft is filled between double-layer tissues, so that the water washing resistance of the fabric is improved. Meanwhile, the polyester filament yarn 2 of the second yarn section b protects the second yarn section b of the break point pad weft yarn, so that the forming of the regional fabric structure of the single-layer structure area is participated, the stability of the regional fabric structure of the single-layer structure area is improved, and the problem of unstable structure caused by the dissolution of the water-soluble vinylon filament yarn is solved.

In the embodiment, by utilizing the water-soluble characteristic of the vinylon filament, after the fabric is subjected to a dyeing process, the continuous water-soluble vinylon filament in the weft of the breakpoint pad is dissolved, the structure of the first yarn section yarn is disintegrated, and the form of the water-soluble vinylon filament is still maintained after the water-soluble vinylon filament is dissolved due to the action of the polyester filament in the second yarn section yarn. Therefore, the first yarn section padded in the double-layer structure area is disintegrated, the kapok staple fiber roving is untwisted and dispersed in the double-layer structure, the first structure area and the fourth structure area are filled with the loose fibers, the loose fibers are fluffy and convex, the fabric structure is further self-adjusted under the synergistic action of the fabric structure and the fabric tissue, the fabric presents a locally convex three-dimensional rectangular array arrangement structure, the convex effect can be generated on the surface of the fabric, and the single-layer structure area can better resist the convex effect.
