[0062] The present invention also provides a preferred embodiment of a method for preparing a sky full of stars weft-knitted jacquard double-sided fabric, which is as follows:

[0063] 1) Yarn selection: 1st and 6th routes are 60D silver yarn, 2nd-5th, 7th-12th routes are 40D / 34F matte nylon FDY yarn and 30D super strong anti-chlorine lycra spandex yarn;

[0064] 2) Knitting machine selection: Choose a 28-needle 34-inch weft knitting double-sided circular knitting machine with a machine speed of 10 rpm;

[0065] 3) Fabric weaving: In the first route, the starry sky yarn is knitted without loops on the odd and even numbered needles of the needle disc, and loops are knitted on the odd numbered needles of the needle cylinder, and the even numbered needles are not knitted;

[0068] For the 3rd, 5th, 8th, 10th and 12th routes, the main yarn and the lining yarn are not knitted on the odd-numbered needles of the needle dial, but are knitted in loops on the even-numbered needles; the odd-numbered needles of the cylinder are knitted in loops, but are not knitted on the even-numbered needles;

[0069] Doffing method: The 2nd to 5th, 7th to 12th routes adopt dense root doffing method, and the main yarn and lining yarn are dropped in each route;

[0070] Yarn feeding amount: 100 needles are used, the yarn feeding amount of the sky-full of stars yarn is 130mm, the yarn feeding amount of the main yarn is 240mm, and the yarn feeding amount of the lining yarn is 80mm. This yarn selection can make the fabric have a better visual effect of the sky full of stars and good stretch elasticity and recovery;

[0071] Finally, the grey cloth is obtained.

[0072] After the grey cloth is woven, it has the initial starry sky appearance, and has a certain internal bone feeling and stretch elasticity, etc. Then the grey cloth is dyed and finished. The process of dyeing and finishing is grey cloth - open width washing (A car rolling) - initial shaping (A car rolling) - dyeing (warp beam dyeing) - post-shaping (A car rolling) - product inspection;

[0073] After the fabric is woven, it is washed in open width and rolled using A-machine to prevent creases, scratches and other quality problems on the fabric.
