V. Description of the invention (i) 25 amendments [Field of the invention] The present invention relates to a sea-island type composite fiber for the weaving of yarn weaving □ and its preparation process' which can be improved as the final product The quality and physical properties of the fluffed yarn knitted fabrics are temporary. [Previous technology] In the seam knitting process of using the sea-island type composite fibers to prepare yarn knitting fabrics, because of the high knitting speed, high-quality yarns are required, especially the smoothness of the yarns. In addition, the processing process after manufacturing yarn knitted fabrics requires a large number of complicated steps, such as weight reduction, fluffing, dyeing, etc., so the thermodynamic properties and viscoelastic properties of yarns need to be properly controlled. In particular, the thermodynamic properties and viscoelastic properties of each sea component and the internal structure of the island component of the sea-island type composite fiber are particularly important when preparing a yarn knitted fabric. The preparation of the sea-island type composite fiber is based on the use of alkaline soluble polymer as a sea component and a fiber-forming polymer as an island component. The sea-island type is made by combining the two components and spinning. Fibers are mainly manufactured to produce fine Daniel fibers. In other words, after preparing the sea-island composite fiber, the sea-island composite fiber of alkaline soluble polymer is treated with an alkaline solution for 5 miles to make the sea surface angle of the sea-soluble polymer? 'As a result, a fine Daniel fiber containing only island components was produced. Taking this 'method of preparing the fine denier fiber from the sea-island type composite fiber' is more advantageous than the method of preparing the fine denier fiber by the direct spinning method 'to obtain the fine denier fiber textile and drawing. »ΙΊ' Ρι.ι | · 1; 1! 45 (Ι〇ν This paper size is applicable to China National Standard (CNS) Α4 size (21〇 × 297 mm) (Please read the precautions on the back before filling this page; >- 17- Printed by the Consumers 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 522181 A7 B7 91.10. 25 Amendment printed by the Consumers' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. 5. The description of invention (2) is excellent, but the former requires a process to It is used to dissolve and remove the sea polymer in an organic solution during the final process after weaving or weaving. Generally, when the sea polymer is used in the sea-island composite fiber woven by yarn, it is mainly used in alkali Soluble soluble polyester copolymer. The reason is that the alkaline component can be used to dissolve the sea component, and the equipment for reducing weight is widely used in the process of reducing the weight of ordinary polyester fibers. Other equipment and the organic solution do not need to cost a high recovery cost. If the island component is nylon, because the nylon is soaked by the alkaline solution when the sea component is dissolved, the dissolution rate of the sea component is faster than Not important. However, if the island component is polyester, the island component will be infiltrated before the sea component is completely dissolved, which is due to the solubility of the polyester to the alkali; weaker, the dissolution rate of the sea component It is so low that the physical properties of yarn 4 are greatly reduced after dissolution. As a result, the fluffing properties become worse, and it is difficult to make the final product have the desired appearance and feel. On the other hand, if the sea ingredient If the dissolving speed is fast, the above problems can be avoided, and the lye density, dissolving temperature and time can be reduced, so the cost required for dissolving can be reduced and the yield can be increased. The content of the copolymer compound. However, if the content of the copolymer compound is increased too much, the sea component will improve the solubility and become an amorphous polymer, which does not have Having a given melting point but only softening Point softening point [], resulting in the textile difficult to use the conventional sea-island type composite fibers prepared by preparative alkali-soluble poly (Read precautions to fill out the back of the page), t ·

Description of the invention (5) The present invention can be adjusted by appropriately adjusting the sea component And the melting viscosity of the island component to improve the fluffing property and the yarn cross-section forming property. Generally, during the textile process, an extruder is used to apply pressure to a spinner to make all the fibers flow. The extruder has a lower flow rate and shear rate, and the spinner's flow rate and Shear rate is higher. The shear stress of this shear rate is called melting viscosity (MV), which varies with polymer properties. However, regarding the sea-island type composite fiber prepared by combining two or more polymers in combination with the textile, since the melting viscosities of the sea components are different from each other, a difference is also generated between the shear stresses, and the result affects the composite fiber. The formation state of the sea and island components and the physical properties of the composite fiber. Therefore, in order to obtain the physical properties required for uniform sea and island cross-section formation for use, it is necessary to select polymers with appropriate melt viscosity sea and island composition. In particular, as for the products of a knitted fabric with wool yarns, in order to exhibit the fine fluffing properties, appearance, and feel of the yarns, the polymers used in the sea-island composite fibers must maintain relative stickiness rather than maintaining their Melting viscosity. The difference between the island component polymer and the sea component polymer of the present invention at a shear rate of 9000 [Ι / s] [AMV9 surface] is that the island component polymer and the sea component polymer have a shear rate of 500 [Ι / s] at 20% to 70% of the difference [aMV500]. That is, ΔΜν 値 at the spinner position should be smaller than ΔΜν 値 at the extruder position. This paper is again suitable for China National Standard (CNS) Α4 specification (210 X 297 mm)

Invention Description (6) In other words, it is caused by the increase of the shear rate The difference in melting viscosity [^ Μν] between the island component polymer and the sea component polymer should be reduced. Otherwise, 'it is difficult to achieve a sufficient amount of drawing and the fluff fibers in the yarn knitting are tangled with each other, so that the directional properties of the island component are reduced, and its weaving properties are reduced. Please refer to the chart shown in Fig. 5 of the present invention, which reveals the change of AMV when all variability increases. As shown in Fig. 5, it is confirmed that the melting viscosity difference between the island component and the sea component decreases gradually as the shear rate increases. Furthermore, the melt viscosity [MVS] of the sea component at a shear rate of 500 to 9,000 [I / s] is preferably smaller than the melt viscosity [MVi] [MVs ^ MVJ of the island component]. The graph in Figure 4 reveals the correlation between the melt viscosity and shear rate of each component. If the melt viscosity [MVS] of the sea component is greater than the melt viscosity [MV1] of the island component polymer, the cross section of the sea-island fiber will be difficult to form. It will cause the amount of the island component to decrease or form uneven sea components, so the fluffing properties during the fluffing process will be poor, and it will be difficult to show the appearance and feel of the final product. Furthermore, the difference in melting viscosity [AMV] between the sea component and the island component is preferably less than 1,000 poise. If the melting viscosity difference [ΔΜν] of the sea component and the island component is greater than 1,000 poises, the island component will stick to each other during the textile process, and the island component may produce unseparated fibers, which remain after the dissolution treatment. Cannot be separated. Based on the above reasons, it is possible to make the fiber fluffing state uneven when the yarn is knitted and

The melting viscosity of the island component polymer can be adjusted by the original viscosity, and the melting viscosity of the sea component polymer can be adjusted by appropriately adjusting the type of copolymer, the quantity and copolymerization of the copolymer. The polymerization conditions are adjusted. For example, when the melting viscosity of the sea component polymer is adjusted throughout the week, a DIMS of 3 to 15 mol% is copolymerized with polyethylene terephthalate, and an average molecular weight of 4 to 20% by weight is added. Polyethylene glycol [0] Compared with preparing a large number of sea-island composite fibers by the method of weaving, drawing, and false twisting, the present invention can prepare yarns with flat properties, so it is more suitable for high-speed yarn weaving . In addition, the appearance and feel of the yarn knitted fabric of the present invention can be improved by appropriately adjusting the thermodynamic and viscoelastic properties of the sea and island components of the yarn. Furthermore, the thermodynamic and viscoelastic properties of the sea and island components of the yarn (textile drawn yarn) on the first godet of the present invention can be adjusted during the manufacturing process in order to adjust the sea and The thermodynamic and viscoelastic properties of the island components are within a predetermined range.

The main melting point peak temperature [Tms] of the sea component is 220 to 235 ° 'and the secondary melting point peak temperature [Tms'] of the sea component is higher than [Tms] 値 about 2 to 10 ° C • Therefore, the maximum temperature in a melting temperature combination of polymer crystals is not considered as the melting point of a crystalline region. The melting point of the same polymer varies according to the size of the crystal. The larger the crystal, the higher the melting point. When a polymer The melting point can be divided into two or more. The main peak of the melting point is a peak at a lower temperature, and the second peak is a peak at a higher temperature. The reason for separating the melting point of a polymer into two is The distribution range of crystal size / group size of polymer is divided by external force into two. If the temperature of the main melting point peak 〜 ~ 11 is higher than the temperature of the secondary melting point peak 値, it means that there are more large crystals than small ones. Of crystals. However, if the temperature of the primary melting point peak is lower than the temperature of the secondary melting point peak, it means that there are more small-sized crystals than large-sized crystals.

In addition, the total melting heat [AHi] of the island component crystals is greater than the total melting heat [AHs] of the sea component crystals by about 2 to 5 5 times. Furthermore, the total heat of fusion [AHy] of the crystals of the textile drawn yarn [y] is about 1 to 1.5 times greater than the total heat of fusion [ΔΗχ] of the crystals of the textile drawn yarn [X].

The viscoelastic index [tan 5] represents the frictional heat and braking caused by the movement of internal molecules when an external force is applied to the polymer The degree of energy loss caused can be obtained by dividing an elastic coefficient by a viscosity coefficient. The first transition peak “a-peak” stands for amorphous transition [glass / 5 :, ': .transhion] Long-distance chain movement of molecules in an amorphous region.
