The present invention addresses the problem of providing fiber of 0.01-0.5 dtex which are used for a sound absorbing/insulating material and with which a fiber assembly with excellent sound absorbing/insulating effects can be obtained. The present invention also addresses the problem of providing a fiber-molded product for sound absorbing/insulating material in which said fiber is used, the product being suitable for a sound absorbing effect of sound less than or equal to 1,000 Hz. The problem can be solved by, in the fiber-molded product, providing fiber for sound absorbing/insulating material having a single-fiber fineness of 0.01-0.5 dtex in which the average value of the normal incidence sound absorption coefficient of the fiber-molded product for sound having a frequency of 200-1,000 Hz is 40% or more, and by using the fiber for sound absorbing/insulating material to mold the fiber-molded product for sound absorbing/insulating material.

A method and apparatus for fabricating a conjugate fiber. Resins having different properties, for example, resins of the same or different components including functional pigments or substances are continuously and alternatively discharged in an endless state by operating a spinning nozzle unit in a melting state, thereby fabricating the conjugate fiber having the different properties in the longitudinal direction of the fiber, and having various surface effects and patterns in the longitudinal direction of the fiber. A conjugate fiber fabricated by the above apparatus and method is also provided.

The present invention relates to a method of preparing wear and cut resistant UHMWPE fibers. In the method, a resin material is added into a ball grinder, and the temperature is controlled, and then a mother liquor is added slowly into the ball grinder and mixed uniformly, and the mixed solution is vacuumed in a sealed container for several hours and extruded by a twin screw extruder, a metering pump, and a spin beam, and finally processed with drafting and hot drawing and winding formation. The fiber so manufactured has the features of soft touch and comfortable wearing.
