Abstract

This disclosure discloses a pretreatment method for opening waste wool textiles, comprising the following steps: spraying an oil agent evenly on the surface of waste wool textiles, and then sealing; the amount of the oil agent is 10% to 25% of the mass of waste wool textiles.

First claim

The invention claimed is:

1. A pretreatment method for opening waste wool textiles, comprising the following steps: spraying an oil agent evenly on a surface of the waste wool textiles, and then sealing;
wherein an amount of the oil agent is 10% to 25% of a mass of the waste wool textiles;
a temperature of the sealing condition is 0° C. to 20° C., and a moisture regain is 30% to 90%;
a sealing time is 20 hours to 30 hours; and
the oil agent includes deionized water, a wool lubricant and an anti-static agent in a mass ratio of 11 to 13:0.8 to 1.2:0.2 to 0.4.

2. The pretreatment method for opening waste wool textiles according to claim 1 , wherein the amount of the oil agent is 15% to 25% of the mass of the waste wool textiles.

3. The pretreatment method for opening waste wool textiles according to claim 1 , wherein the amount of oil agent is 19% to 21% of the mass of the waste wool textiles.

4. The pretreatment method for opening waste wool textiles according to claim 1 , wherein the temperature is 0° C. to 10° C.

5. The pretreatment method for opening waste wool textiles according to claim 1 , wherein the moisture regain is 80% to 90%.

6. The pretreatment method for opening waste wool textiles according to claim 1 , wherein the mass ratio of the deionized water, the wool lubricant and the anti-static agent is 12:1:0.3.

7. A method for opening waste wool textiles, comprising the following steps: before an opening process, performing a pretreatment to the waste wool textiles by using the pretreatment method according to claim 1 .
