記Ａ〜Ｃの方法がある。(Prior Art) Wool cloth has the drawback that it shrinks greatly when washed at home and becomes felt, and various shrink-proofing methods have been developed to improve this. For example, as described in detail in "New Dyeing and Processing Course", Vol. 11, pp. 150-161, there are the following methods A to C.
A.羊毛繊維のスケールを，強酸で濃度の高い次亜塩素酸

Polydimethylsiloxane having an amino group and a silanol group as functional groups is generally called a silicone elastomer, and when it is processed into a fiber by using methylhydrogensiloxane and an organometallic salt-based catalyst together, it crosslinks on the fiber surface. It forms a good film having a bond. As a typical example, Ultratex ESC (product of Ciba-Geigy) is commercially available.
This silicone elastomer has been conventionally used as a softening agent or a stretchability improving agent.

Do ~ 2 minutes. The curing is performed at 150 to 160 ° C for 1 to 2 minutes.
In this case, if the temperature is 150 ° C or lower, the cross-linking reaction of the silicone elastomer film will be insufficient, resulting in poor washing durability, and if the temperature is 160 ° C or higher, the problem of yellowing or embrittlement of the wool fabric occurs .

に耐え得る撥水性能が発揮されるようになる。(Working) When low temperature plasma treatment is applied to the wool fabric, the hydrophobic epicuyicle layer on the surface of the wool fiber is hydrophilized and the wetting property is greatly improved, and the adhesion to the resin to be processed next is improved. Greatly improved. In this state, when resin processing is performed with a resin liquid consisting of a fluorine-based water and oil repellent finishing agent and polydimethylsiloxane, methylhydrodienesiloxane, a strong silicone elastomer film is formed on the wool fiber surface with improved wetting characteristics. As a result, the water-repellent performance which is wash resistant and is extremely excellent and the fluorine-based water-repellent oil-repellent resin which is tightly bound are exerted the water-repellent performance which can withstand repeated washing.
