Preferably, the preset water level is a middle water level, and the middle water level can make the detergent have moderate concentration in the washing process, so as to meet the requirement of cleaning rate. While low water levels increase wool shrinkage and are not conducive to laundering woolen garments.
The rotation time required for the rotation in the rotation-stop period of the first rotation-stop ratio is 0.5-0.8S, and the rotation stop time is 0.2-0.4S. The process is to make woolen clothes fully soaked by water and quickly washed, and ensure the washing rate of the woolen clothes.
The time required for rotation in the spin-stop period of the second spin-stop ratio is generally 2 to 5S, and the spin-stop time is 9 to 15S.
The speed of the water flow in the first washing process is fast, wool clothes can be fully stirred, the cleaning rate of the wool clothes is effectively improved, the stop time in the second washing process is long, the wool clothes and the impeller can be fully stirred, the stop time is long, the wool clothes are soaked, and therefore the shrinkage rate is low.
In the specific embodiment, the rotation required time in the rotation/stop period of the second rotation/stop ratio is 3S, and the rotation stop time is 11S. Compared with the existing wool washing method, the washing mode has the advantages that the cycle rotating time is prolonged, the washing rate can be further improved, meanwhile, the stalling time is prolonged, wool clothes can be effectively soaked, and the shrinkage rate can be reduced.
In the embodiment, the rotating time in the rotating-stopping period of the second rotating-stopping ratio is less than the stopping time, so that wool clothes can be soaked in sufficient time, and the cleaning rate can be effectively improved; the rotation time is shorter than the stalling time, so that the friction between the wool clothes and the inner barrel and between the wool clothes and the impeller in the washing process can be reduced, and the reduction of the shrinkage rate is realized.
The first rotation-stop ratio and the second rotation-stop ratio in the embodiment refer to the periodical rotation and stop of the impeller.
In the washing process, the washing program comprises a washing process in a first washing process and a second washing process, after the washing process is finished, the washing machine enters a rinsing process, the rinsing process comprises a rinsing process in the second washing process, in the embodiment, the rinsing process comprises two rinsing processes, and the sum of time required by the two rinsing processes is less than the time required by the washing process. The rinsing process mainly cleans the detergent on the woolen clothes, and washes the woolen clothes again at the same time.
After the rinsing program is finished, the washing machine enters a dehydration program, wherein the rinsing program comprises a first dehydration process and a rinsing process, the first dehydration process is carried out before the rinsing process, and the dehydration program comprises a second dehydration process; wherein the continuous dewatering time in the first dewatering process is less than the continuous dewatering time in the second dewatering process. The first dehydration process and the second dehydration process comprise intermittent dehydration, continuous dehydration and inertial dehydration, and after the second dehydration process is finished, the drain valve is closed and the brake is carried out. Specifically, the continuous dehydration time of the first dehydration process was 10S, and the continuous dehydration time of the second dehydration process was 20S.
Specifically, the sum of the time required by the first washing process and the time required by the second washing process is 9-14 min; the time required by the rinsing process is 1.5-4 min; and the time required for the first washing process was 1 min. Preferably, the time required for the washing process in the washing program in this embodiment is 11.5min, and the time required for the single rinsing process in the rinsing program is 2 min.
The wool laundry washing program provided by the embodiment comprises:
a water inlet program, a washing program, a rinsing program and a dewatering program; wherein the washing program includes a first washing course and a second washing course of the woolen laundry.
Specifically, wherein the washing program comprises 11.5min of washing the laundry, 30S of balancing; the rinsing program comprises water drainage, a dehydration process 80S, a brake 5S, clothes washing 2min, balance 30S, water drainage, a dehydration process 80S, a brake 5S, clothes washing 2min and balance 30S; the dehydration procedure includes water drainage, dehydration process 115S, and brake 5S.
The following table shows the results of the measurement of the washing rate of the woolen clothes after washing in this example:

| Stain or soil | Measured value | Contrast value | Limit value |
| Carbon black | 104.3％ | 78.9％ | >75％ |
| Blood stain | 98.7％ | 83.2％ | >90％ |
| Chocolate and milk | 99.7％ | 77.1％ | >80％ |
| Red wine | 106.7 | 91.5％ | >90％ |
The following table shows the results of measuring the shrinkage of the washed woolen clothes in this example:
TABLE 2
| Measured value | Contrast value | Reference machine | Limit value |
| 0.76 | 0.91 | 0.95 | ≤1.0 |
Wherein, two pulsator washing machines A, B of the same model are adopted to wash the same woolen clothes, wherein the pulsator washing machine A uses the method for washing woolen clothes provided by the embodiment; the pulsator washing machine B washes woolen clothes of the same size and the same area using a method of washing woolen clothes in the prior art. The areas of the carbon black, the bloodstain, the chocolate, the milk and the red wine sprayed on the two woolen clothes are the same, and in order to ensure that the parameters at the early stage of the test are consistent, the stock solution of each kind of stain is taken out from the same container.
The limit value of the expansion and contraction rate is 1, and when the expansion and contraction rate is smaller than the limit value, the abrasion after washing is smaller; as can be seen from table 2, when the stretch ratios are compared, although the test data obtained by both washing machines a and B are smaller than the data of the reference machine, the stretch ratio of the woolen clothes washed by washing machine a is smaller than that of the woolen clothes washed by washing machine B, and the woolen wear after washing by washing machine a is smaller than that of washing machine B, so that the life of the woolen clothes can be prolonged.
According to relevant regulations, the wool clothes washing rate is larger than a limit value; from table 1, it can be seen that the washing rate of the method for washing woolen clothes by using the washing machine provided in this embodiment is much higher than the limit value, and the washing rates of the four stains on the woolen clothes washed by washing machine a are all greater than the washing rates of the four stains on the woolen clothes washed by washing machine B.
The shrinkage rate of woolen clothes washed by the method in the embodiment is less than that of woolen clothes washed by the method in the prior art, and although both are less than the limit value, the method in the embodiment has better effect than the method in the prior art in long term use.
The limit in this example is the Australian wool standard limit.
