Example Embodiment

[0154] The chloride ion concentration contained in the wool fibers obtained in Example 1 was determined by the following method. The wool sample was boiled in distilled water in distilled water in accordance with JIS K 0127 chloride concentration, and the extracted chloride ion was measured by an ion chromatograph. Determination of Industry Technology Center Environmental Materials Rooms depends on "Aichi Center for Industry And Science Technology".

Abstract

Provided is a method for efficiently producing anti-shrinkage animal hair fibers having sufficiently high water-resistant launderability in a sliver form while maintaining inherent water repellency as one of features of animal hair fibers without deteriorating the texture and other features. The method for producing anti-shrinkage animal hair fibers is characterized in that a sliver, which is a continuous body of animal hair fibers, is immersed in a diamine aqueous solution containing an alkaline agent at 30-45 DEG C, and immersed in a silicon solvent with a dibasic acid chloride dissolved therein in a state in which the diamine is attached to the sliver, thereby coating the animal hair fibers with a polyamide.

Description

technical field [0001] The present invention provides a method for producing shrink-resistant animal hair fibers excellent in water-based washing resistance, and in particular provides a method for minimizing the discharge of adsorbable organic chlorine compounds from the production process and the residue of chlorine compounds in the fibers. The invention discloses a method for manufacturing a mild-environment shrink-resistant animal hair fiber. Background technique [0002] Regarding the shrinkproof treatment of wool fibres, there has been a general treatise by R.W. Moncrieff in 1953, published by London TheNational Trade Press LTD. The main treatments reported are: chlorination using hypochlorous acid, chloric acid, perchloric acid or chlorine gas, oxidative treatment using potassium permanganate and ozone, chloramine treatment, and enzymatic treatment. However, its mainstream is chlorination, which continues today and has even been applied to knitted fabrics, woven fabr...
