Problems solved by technology

[0006] Obviously, if the cashmere fiber content of the fabric is reduced, its handle style will be quite different from that of pure cashmere products; in addition, since the viscose-based heat storage and temperature-regulating fiber is regenerated cellulose fiber, it is more alkali-resistant and less acid-resistant, and cashmere The fiber is a natural protein fiber, which is more acid-resistant than alkali-resistant. The chemical properties of the two fibers are quite different. The acid-base environment required for dyeing is different, and the dyeing rate is also very different. It is difficult to control the temperature and acid-base conditions. N

Embodiment 1

[0037] A two-ply knitted fabric with a connection point density of 12.5% ​​is produced.

[0038] This example (see figure 2) The double-layer knitted fabric includes surface fabric 1 or outer fabric 1, inner fabric 3 and middle connecting yarn 2, the surface fabric 1 is woven from the surface yarn, and the inner fabric 2 is made of the inner yarn The outer and inner layers of fabric are connected by connecting yarn 2 to form a whole double-layer knitted fabric. The surface layer yarn is spun from cashmere fiber, and the inner layer yarn is regulated by heat storage. The warm fiber and the cashmere fiber are blended at a mass ratio of 40:60, and the connecting yarn 2 is purely spun from the heat storage and temperature regulating fiber. The specifications of the heat storage and temperature regulating fibers are: length 40mm, fineness 2.0dtex; the specifications of cashmere fibers are: length 40mm, fineness 15um.

Abstract

The invention discloses a double-layer knitted fabric and a knitting method thereof. The double-layer knitted fabric comprises a surface fabric and an inner fabric and is characterized in that the surface fabric is knitted by surface yarn, the inner fabric is formed by interweaving the inner yarn and connecting yarn, the connecting yarn is used to connecting the surface fabric and the inner fabric to form a whole of the double-layer knitted fabric, the surface yarn is made by spinning cashmere fibers, the inner yarn is made by mixedly spinning thermal-storage and temperature-regulated fibers and cashmere fibers under the mass ratio of 30-70 to 70-30, and the connecting yarn is made by pure spinning the thermal-storage and temperature-regulated fibers. The connection method of the connecting yarn is that according to the design requirements of density of connection points, tucking stitch is used in doing the lower stitch, looping stitch is used in doing the upper stitch, and the process repeats, and thus, the loop system of the connecting yarn of the thermal-storage and temperature-regulated fibers is achieved, and the thermal-storage and temperature-regulated fibers and coils of the inner yarn form a full column. The knitting method is used to complete the knitting of the double-layer knitted fabric on a computerized flat knitting machine.

Description

technical field [0001] The invention relates to functional textile fabric technology, in particular to a double-layer knitted fabric and a weaving method thereof. Background technique [0002] Heat storage and temperature regulating fiber is a new type of fiber with temperature regulating function developed by combining phase change heat storage materials and chemical fiber manufacturing technology. It is to implant the phase change material into the fiber in the form of microcapsules, so that it can undergo a liquid-solid phase reversible transition according to the change of the external environment temperature. During the transition process, it absorbs heat from the surrounding environment and stores it. Inside the fabric containing heat-storing and temperature-regulating fibers, or release the heat stored in the fabric, a microclimate with a basically constant temperature is formed around the fabric, thereby realizing the temperature-regulating function. [0003] Tradit...
