Hereinafter, the present invention is the mixture of the products on the drawing data transmissions take other.

As above-mentioned molten thermoplastic cellulose derivative fibers of radiation emanating from the fiber color can be stored and properties even when radiation immediately thermoplastic cellulose is freezing temperature radiation maximum limits to support door number generation rate abruptly solidification point, further, a system of high speed spinning room inside 3, 500mpm or more cutting the, good mechanical properties and excellent touch a door number point at the high pressure liquid coolant number thermoplastic cellulose ultrafine fibers has been difficult.

The number including number 1 component in the present invention cellulose ester and a plasticizer; and water soluble polyester including number 2 component; and then the above-mentioned thermoplastic cellulose derivative fabric including a number public box fixing by fitting his number. Radiation through a radiation immediately melt-spinning by preventing improve cellulose is abruptly so that solidification, more fast radiation can be bonded by 3, 500mpm increase, thermoplastic cellulose derivative fibers can be retains the value corresponding to the number of bath. In addition, a stand-alone number by said thermoplastic cellulose derivative fibers ([...]) solution component from composite fiber yarn fiber thermoplastic cellulose derivative by the ultrafine fibers excellent superfine angersensitivityunder public affairs number can be.

Cis - core of the present invention composite fibers (sheath provided core) type, even when (Island in the Sea) type, side by side (Side by side) may be NP split yarn or the like, the number 1 and number 2 component to each component and not one specifically number into holes preferably including composite fiber form.

The present invention refers to a component water soluble polyester plasticizer cellulose ester and glass beads including number 2 component including number 1 number by polyesters is isolated from external air for protecting molten metal by radiation heat loss cellulose is cellulose immediately prevent abruptly so that solidification can be radiation, preventing rapid cellulose does not give spaced and the excellent workability, retains the can be improved, more fast radiation 3, 500mpm assembled by the productivity can be significantly increased.

Figure 1 shows a core of the present invention also a preferred laser output according to cis - (sheath provided core) for washing and cross-sectional drawing, such as cis - 1 also it became at the time of (sheath provided core) for washing the core preferably than if said number 1 component core component (21) is used as a, sheath component number 2 component (20) can be made disclosed. On the contrary, it has a core component number 2, number 1 component when a sheath component radiation generated due to rapid freezing of cellulose this old air section of the service cannot be executed for guaranteeing the quality product and high speed radiation number cannot, core component water soluble copolyester when door is a stand-alone number rather strength reduced number thereof can.

In addition, Figure 2 shows a laser output according to a preferred of the present invention also (Island in the Sea) for washing and even cross-sectional drawing, number 1 (Island in the Sea) of these fibers even when the component or the component (31) in which, preparation of component number 2 component (30) to be a which (Island in the Sea) of these fibers. At this time component or the (31) preferably has a number of 2 to 8, component or (31) filament size of 0. 1 to 1 D implementation being. On the other hand, number 2 component and vice versa corresponding electrodes, island type number 1 component due to rapid radiation when a high speed takes place in a section of this old cellulose air cannot be guaranteeing the quality cannot radiation freezing and non-oxide ultrafine fibers door number number number article there could disclosed.

Figure 3 shows a preferred laser output according to of the present invention also side by side (Side by side) for washing and cross-sectional drawing, and Figure 4 NP division yarn cross-section, said side by side (Side by side) of the present invention number 1 because each location at which equal or NP division of 4.6 formed over the component, it is desirable if a component number 1 number 2 component in weight, least number 2 position is not be particularly number one.

Such as composite fiber of the present invention said number 1 component is cellulose ester and plasticizer included in number without using a tool.

Some or all said cellulose ester cellulose ester bond has been substituted by a hydroxy cellulose derivatives, strong hydrogen bonds between the hydroxyl groups of cellulose is mixed with a plasticizer to weaken its number is to substrate.
