The Details That Should Be Paid Attention To in The Production Of Sealing Tops

1. The average fineness of the compounding component should not be too different from the average fineness of the main component, and generally should be controlled within 2 micrometers.

2. The fineness of wool strips made from raw materials will change, and this factor should be considered in the wool matching design. The average diameter of the fibers of national wool and Australian wool tops increases by about 0.3 microns.

3. If the performance of the raw materials is quite different, it is generally not suitable to be used together, except for those with special requirements. Such as national wool and Australian wool, it is generally not suitable to use together.

4. Although the coarse-cavity hair content in the finished wool top after carding has been reduced, it is still selected according to the quality requirements of the wool top in the design of wool matching.

5. The number of grass bristles used in the hair matching design should be properly controlled according to the weeding ability of the equipment and the type of grass bristles.

6. The color and feel of each component raw material should be relatively close, and according to the use of the finished wool top, it can be divided into two categories: light dyeing and medium dark dyeing, and wool matching design.
