Embodiment 1

[0024] (1) Raw material selection

[0025] The outer layer of the fabric is made of fine denier polyester fiber with a linear density of 150D, a single fiber fineness of 1.1dtex, and a Z-twisted filament twist. The linear density of the cross-shaped polyester fiber in the inner layer is 150D, and the twist direction of the filament is Z twist. The density of polyester filaments in the middle connecting thread is 75D, and the twist direction of the filaments is untwisted.

[0026] (2) Weaving process

[0027] A three-dimensional warm-keeping knitted fabric comprises an outer layer, an inner layer and a middle layer. The structure described was obtained by the following method.

[0028] The cylinder needles go through 1, 3, 5, 7....... Odd-numbered needles form a circle first, followed by 2, 4, 6, 8........... ..Even numbered stitches form a loop.

[0029] Then the dial needles pass through 1, 3, 5, 7...... odd numbered needles to form a circle first, followed by 2, 4, 6, 8...

Abstract

The invention relates to three-dimensional thermal insulation knitted fabric and a preparation method thereof. The fabric comprises an outer layer, an inner layer and connecting silk yarns, wherein the outer and the inner layer are formed through the twice loop formation mode, and the connecting silk yarns are wound between the outer layer and the inner layer in a reciprocating manner to enable the outer layer and the inner layer to be connected together; the outer layer is formed by micro-thin polyester fiber, the inner layer is formed by non-circular cross-section fiber, and the connecting silk yarns are polyester filaments. The preparation method comprises the following steps: obtaining fabric via knitting of yarns, presetting, dyeing, functional finishing, drying, secondary setting, and obtaining the thermal insulation knitted fabric. The thermal insulation knitted fabric has the characteristics of excellent stiff and smooth effect, lightness, thermal insulation, firm handfeel, excellent snagging prevention and the like, overcomes the defects of easiness in snagging, infirm handfeel, poor thermal insulation and the like, is simple in structure and low in cost, and has excellent application prospects.

Description

technical field [0001] The invention belongs to the field of knitted fabric and its preparation, in particular to a three-dimensional warm knitted fabric and its preparation method. Background technique [0002] The three-dimensional and thermal fabrics involved in the present invention have three types of conventional methods, one is formed by compounding and adding fillers in the middle of the adhesive, but there are disadvantages such as high energy consumption and low environmental protection; the other is the weaving process: It is formed by different interweaving methods of warp yarn and weft yarn; the last category is traditional knitted three-dimensional fabric. [0003] Patent name "A Silk Cotton Three-dimensional Fabric" (Application No.: 201010194416.3, Publication No.: CN102268766, Publication Date: 2010.06.07), the above-mentioned fabric is interwoven twice and filled with the third set of weft yarns by warp yarns and weft yarns on the weaving machine The metho...
