いるには不十分な繊維であった。BACKGROUND OF THE INVENTION Camel hair fiber is a natural fiber having excellent physical and chemical properties and has been traditionally prized as animal hair after cashmere, but its use is limited due to its low friability. , Futons, batting for winter clothes, and heavy-duty yarns were used, so they were limited to sweaters and thick woolen fabrics. That is, the fibers were not sufficiently entangled with each other due to extremely poor friability, and the fibers were insufficient for use in high-grade fabrics.

Further, in Japanese Patent Laid-Open No. 56-79759, there is disclosed a method of bleaching animal hair in which a proteolytic enzyme is used in combination with a bleaching agent to carry out shrink-proofing at the same time as bleaching. Has proposed a method for uniformly removing the scale of wool fiber by subjecting the surface of animal hair fiber to an oxidation treatment in advance and then treating it with a proteolytic enzyme in a saturated solution of an inorganic salt.

No. 27274 discloses a method of causing an enzyme to act on animal hair fibers, but the target is mostly wool, and the purpose is to remove scale of wool or to crosslink the scale to impart shrink resistance. In most cases, the dyeability is improved, and there are almost no examples in which proteolytic enzymes are applied to camel hair fibers for the purpose of the present invention.

れる。The camel fiber of the present invention is obtained by treating camel hair that has been washed to remove stains with a proteolytic enzyme. The proteolytic enzyme used in the present invention acts on a protein, proteose, peptone, polypeptide, etc. to hydrolyze a peptide bond,
It means an enzyme that releases an amino group and a carboxyl group. Specific examples include enzymes of animal origin such as pepsin, trypsin, chymotrypsin and capten, enzymes of plant origin such as papain, promelin or ficin, and bacterial sources such as mold protease, yeast protease and bacterial protease. The proteolytic enzyme is used.

The treatment is usually carried out in a water bath in which the enzyme is dissolved or dispersed, and the bath ratio is in the range of 1: 5 to 1:50, preferably 1:10 to 1:30. The treatment temperature is usually from room temperature to about 60 ° C., and the temperature is optimum for each enzyme.

Usually, it may be adjusted using a commercially available buffer. The proteolytic enzyme is usually used in an amount of 0.1 to 10% by weight based on the dry weight of camel hair. In the present invention, in order to prevent the scale from standing slightly and to prevent damage to other parts, 0.5 to 6% by weight is usually used as a preferable range.

維製品として評価が高い。The camel hair fiber thus obtained has the effect of a properly standing scale to improve the entanglement between the fibers, so that a yarn that can be used for high-quality clothes with a small number of fine count fluff can be obtained. The woven fabrics and knits produced using this yarn have a new texture different from wool, and are highly evaluated as new differentiated textile products.
