Description

Wool blanket and production process thereof and weaving ring wool machine for weaving the wool blanket

Technical field

The invention relates to a wool blanket and a production process thereof, and to a cut loop machine for weaving the above wool blanket.

Background technique

With the improvement of people's living standards, the quality requirements for daily necessities are getting higher and higher. Wool blankets are often laid on cars, couches, seats, beds, etc., and wool blankets have received widespread attention because of their good breathability, warmth and moisture resistance.

Most of the wool blankets are made by using the cut loop knitting machine and the cut loop process. However, the wool blankets woven by the cut loop knitting machine in the prior art have low density and small weight, in terms of touch and warmth. It is incomparable with real wool. Therefore, the wool blankets currently on the market generally process the real sheepskin and then suture several real sheepskins. For a complete real sheepskin, the wool in different parts of the sheep body has some differences in color, length, density and flexibility. There are also some differences in wool from different real sheepskins. The wool blankets that result in the stitching of multiple real sheepskins are not only uneven in color, but also have problems of length and density of wool at different positions, which reduces the overall quality of the wool blanket. Moreover, the wool blankets stitched with sheepskin are expensive, which limits the number of consumers and the market competitiveness is poor.
