Problems solved by technology

[0002] In the prior art, in order to improve the texture of the fabric, more and more double-layer fabrics are used. In order to further improve the thickness of the fabric, in the prior art, weft yarns are usually introduced between the double-layer weaves of the fabric to make the fabric texture Full of thickness; however, there are the following defects in directly introducing the weft in-lay yarn into the double-layer structure: 1) The process of directly introducing the weft in-lay yarn limits the selection of materials for the weft in-lay yarn, and it cannot be used for fibers with excellent functionality but low spinnability. 2) The pad weft yarn that is placed between the double-layer fabrics exists in the form of yarn, which has limited effects on enhancing the thickness and three-dimensionality of the fabric.
[0005] Although the fabrics prepared by the above methods all adopt a double-layer structure and select yarns with specific functions and structures to prepare functional textiles, due to the structural limitations of the double-layer fabrics and the functional limitations of the selected yarns, The functional improvement of the prepared textiles is limited, and the functional yarns used are exposed, and the functional yarns are easy to wear and fail and are not washable, and the service life is not long

preparation example Construction

[0038] see Figure 1 to Figure 7 As shown, the invention provides a kind of preparation method of self-adjusting fabric, comprises the steps:

[0039] S1, determining the organizational structure of the first structural area, the second structural area, the third structural area and the fourth structural area, and determining the ratio of the latitudinal width of the first structural area to the second structural area;

[0040] S2, selecting the warp yarn, weft yarn and breakpoint pad weft yarn of predetermined raw materials;

[0041] S3, weaving after threading and reeding according to the drawing on the machine;

[0042] Wherein, in the first structure area and the fourth structure area, the breakpoint pad weft yarn does not participate in interweaving, but is only placed between two layers of weave in the double-layer weave structure;

[0043] In the second structure area and the third structure area, the weft yarn of the break point pad participates in interweaving;

Embodiment 1

[0055] A preparation method of self-adjusting functional wall covering fabric:

[0056] S1, determine that the inner and outer weaves of the first structure area A and the fourth structure area D adopt plain weave to form a double-layer structure; the second structure area B and the third structure area C both use two upper and two lower twill weaves to form a single-layer structure ; Determine the ratio of the latitudinal width of the first structure area to the second structure area as W A :W B =1:4;

[0057]S2, determine the material (as shown in table 1) of the warp yarn, weft yarn and breakpoint pad weft yarn of the first structure area A, the second structure area B, the third structure area C, the fourth structure area D; according to table 1, The breakpoint weft yarn is composed of kapok roving, water-soluble vinylon filament 1 wrapped continuously outside the kapok roving, and polyester filament 2 intermittently wrapped outside the kapok roving;

[0058] S3, accord...

Embodiment 2

[0083] Preparation of a self-adjusting woven thermal fabric:

[0084] The difference from Embodiment 1 lies in the difference in fabric material, structural design and weaving process parameters, as shown in Table 4, and other steps are basically the same, and will not be repeated here.

[0085] Table 4 Organization structure design and weaving process parameter setting of embodiment two

[0086]

[0087]

[0088] In the fabric, similar to Example 1, its A and D structural regions form a fluffy and raised double-layer structure, and the surface layer structure is PI, which provides good heat insulation, moisture-proof, and antibacterial properties; the inner layer structure is cotton , providing good wearing comfort. After untwisting the breakpoint pad weft yarn, the PI spun yarn is distributed between the double-layer fabrics in the form of loose fibers. The bulkiness of the loose fibers and the heat insulation performance of PI endow the fabric with better heat insulati...

Abstract

The invention provides a self-adjusting fabric and a preparation method thereof. The self-adjusting fabric comprises a double-layer structure area arranged diagonally, a single-layer structure area arranged diagonally, and breakpoint mat weft yarns arranged in the aforementioned structure area. The breakpoint mat weft yarns include staple fiber rough yarns, water-soluble vinylon filaments that arecontinuously wrapped around the staple fiber rough yarns, and polyester filaments that are intermittently wrapped around the staple fiber rough yarns to form a first yarn section with no polyester filaments alternately distributed and a second yarn section with polyester filaments. The first yarn section is arranged between double-layers of structures. During dyeing, the breakpoint mat weft yarnsin the double-layer structure area is untwisted and dispersed and then put in the double-layer structure area to make the structure area convex; and because of polyester filament wrapping effect, thebreakpoint mat weft yarns in the single-layer structure area continue to be interwoven in the single-layer structure area in the form of yarns to obtain the self-adjusting fabric with a single-layerdouble-layer concave-convex structure. By selecting breakpoint mat weft yarns with different functional characteristics, fabrics with different functionalities can be prepared.
