The invention relates to a preparation process of short
wool tops in 18.5 microns. The preparation process comprises the following specific steps: 1,
wool selection: 50%-60% of lamb
wool, 30%-40% of weaned lamb wool and 5%-10% of early sheared wool; 2, opening, wool washing and
drying: respectively carrying out opening, washing and
drying on the three kinds of wool in the step 1, controlling the wool washing temperature of the early sheared wool to be 42-46 DEG C, the wool washing
machine being provided with 3-5 tanks, a washing agent being not added into the first tank and the last tank, controlling the washing temperature of the lamb wool and the broken lamb wool to be 35-40 DEG C, controlling the number of the tanks of the wool washing
machine to be 4-5, the first tank and the last tankbeing filled with clear water, adding the washing agent into the rest tanks, and
drying the cleaned wool; 3, mixing the wool; and 4) carrying out pre-gilling,
combing and post-gilling processes. According to the preparation process of the short wool tops in 18.5 microns, the wool tops are stable in quality and belong to the category of qualified products, the supply amount is increased, the market requirement is met, the production efficiency is improved, and the
energy consumption is reduced.
