[0033] (3) Add material II and 1 part of sodium gluconate to material I, mix thoroughly and let it stand for 30 minutes, then raise the temperature to reflux state at a heating rate of 10°C / min and keep mixing for 10 minutes, and ...

Embodiment 3

[0037] The remover prepared in Example 1 and Example 2 is used to remove the natural impurities of wool raw wool. The method of use is: first soak the wool raw wool in the prepared remover, take it out after 5 minutes, rinse it with clean water, and remove it. The effect is measured.

[0038] The measurement results show that the removal rate of natural impurities reaches 99.1% and 99.3% by using the remover prepared in Example 1 and Example 2 to treat the raw wool respectively, and the peculiar smell of the treated raw wool is greatly reduced.

Abstract

The invention discloses a natural impurity remover for raw wool, and relates to the technical field of wool processing. The natural impurity remover is prepared from the following raw materials in parts by weight: 5-10 parts of pregelatinized starch, 2-4 parts of modified polyoxyethylene, 2-4 parts of beta-cyclodextrine, 1-2 parts of poly dimethyl diallyl ammonium chloride, 1-2 parts of lanonol, 1-2 parts of sodium gluconate, 0.5-1 part of coconut powder, 0.5-1 part of polyvinyl alcohol resin, 0.5-1 part of sodium bicarbonate powder, 0.3-0.5 part of sodium dihydrogen phosphate, 0.1-0.3 part of N-hydroxymethyl acrylamide and 100-150 parts of water. The natural impurity remover for raw wool can effectively remove natural impurities with the removal rate reaching above 99%, cannot cause damage to wool fibers of raw wool, and can guarantee the softness and bulkiness of raw wool.

Description

[0001] Technical field: [0002] The invention relates to the technical field of wool processing, in particular to a natural impurity remover for wool raw wool. [0003] Background technique: [0004] The wool cut from sheep is called raw wool, which contains a lot of impurities in addition to wool fibers. Because raw wool contains impurities, it cannot be directly used in wool spinning production. Raw wool impurities are divided into two types: natural impurities and foreign impurities. Natural impurities are mainly the secretions of goats, sheep sweat, and excrement of the sheep itself; foreign impurities are mainly grass clippings, grass seeds and sand. In order to remove the natural impurities on the raw wool, the raw wool needs to be scoured. Since these impurities are insoluble in water, emulsifiers or organic solvents are needed to wash them off. However, a large amount of emulsifiers will have a certain impact on the wool fiber of the raw wool, reducing the soft feel ...
