Warping is the first step in the weaving process. The purpose of warping is to arrange the bobbins in parallel and wind them onto the warping shaft for sizing. Do you know how a product warping needs to be done?

Take TC3232 13070 63 "2/1 twill as an example:

First, convert the weight in kilometers

The warp used in the product is TC32s. According to the definition of yarn count and the conversion factor, we can convert TC32s yarn, which weighs 18.359 grams per kilometer. The actual yarn count needs to be measured.

The second step is to measure the net weight of the original yarn

In theory, the net weight of each bag is 25KG, and each bag is 15 /12 /8. Depending on the size of the roll, the weight of the cylinder is different. Taking 12 packs as an example, the net weight of each drum yarn is 2.083KG. The actual weight measurement is also required.

The third step is to calculate the length of the barrel yarn

According to the net weight of the barrel yarn and the grams per kilometer of yarn. It can be calculated that the length of the barrel yarn is 113459.339 meters.

The fourth step is to calculate the total number of warp and the number of warping axes

Warping length According to the variety of warp density and width, the two multiplied, you can get the total number of warp. It used to be 8190 for example.

According to the size of the warping frame of the warping machine and the reed number of the fixed reed, the range of the number of warping roots can be determined. We can choose 630 / axis, then the number of axes is 630 / axis 13 axis =8190.

The warping length can be determined according to the length of drum yarn and reel capacity. For a 2 meter wide axis disk, the previous warping length can be 55,000 meters/axis 2 axes = 110,000 meters.

At this point, the warping process can be preliminically determined

Yarn count: TC32s

Axis: 583 / axis 13 axes

Warping length: 55,000 meters
