- PCT material melting point 290 ° C
- PBT poly-butylene-terephthalate
- co-PCT co-poly 1,4-cyclohexanedimethanol terephthalat
- PCT resin and PP resin were introduced into individual spinning nozzles, melt spun at spinning conditions of spinning speed 600 m / min, stretched 3.5 times, and heat-treated at 120 ° C. to prepare a sheath-core composite fiber of PCT / PP type.
- the mixing ratio between PCT resin and PP resin was prepared in a 70:30 weight ratio.
- the web made of the sheath-core composite fiber prepared above was maintained at an upper and lower temperature of 200 ° C., and thermally bonded in a double belt press having a belt speed of 1.0 m / min to form a fibrous substrate.
- a side-by-side composite fiber was prepared by performing the same spinning conditions as in Example 3, except that the PCT resin and the PP resin were melt-spun into an extruder equipped with a side-by-side spinning nozzle. And the fibrous base material was formed by the process similar to the said Example 3.
- Example 1 On one surface of the fibrous base material of Example 1 containing the PCT fiber (melting point 290 ° C), a spacer fabric of PCT / PBT was laminated, and the fibrous base material containing the fiber of PCT material (melting point 290 ° C) thereon. was further laminated and interlayer bonded using a hot press to prepare a cushioning member.
- the cushion member was manufactured in the same manner except that the fibrous substrates laminated in the multilayer structure of Example 5 were needle-punched 300 times / mim / cm 2, and then manufactured by a hot air adhesive method at 200 ° C.
- Example 1 except that the fiber web was formed by blending 8: 2 weight of LM PET (single yarn fineness 6 denier) on polyethylene terephthalate (PET) fibers (Woongjin Chemical Co., Ltd., single yarn fineness 7 denier). The same was done.
- LM PET single yarn fineness 6 denier
- PET polyethylene terephthalate
- the cushion member produced in Examples 1 to 4 of the present invention was confirmed to be lighter than Comparative Example 1.
- 10% or more compared to Comparative Example 1 made of PET fibers can be manufactured with a low unit density cushion member.
- the cushion member of the multi-layer structure manufactured in Examples 5 and 6 of the present invention can manufacture a thicker cushion pad through the composite with the spacer fabric, and satisfied the physical properties as a cushioning material.
- Hardness, compressive permanent shrinkage, air permeability, compression recovery rate, and the like of the cushion members prepared in Examples 1 to 6 were measured to determine whether or not they could be utilized in the cushioning material.
- the hardness is a measure of the load imposed when compressing up to 70% of the thickness of the nonwoven fabric, compressive permanent shrinkage is pressurized to 50% of the nonwoven thickness for 22 hours at 70 °C based on KS M 6672, and then at room temperature The residual permanent strain after 30 minutes recovery was measured.
- air permeability was measured by the Frazier method (Frazier Method) air permeation was measured at a pressure of 125 Pa, the recovery rate is recovered after compressing the nonwoven fabric to 50gf / cm 2 using a measuring device (Kawabata Evaluation System-FB3) It is a measure of accuracy.
- Example 5 and Example 6 made of a multi-layer cushion member, high hardness values were confirmed. These results provided a high binding force by inserting a spacer fabric between the fibrous substrate layers of PCT material.
- the multi-layered cushion member exhibited the best physical properties in compression recovery rate and compressive permanent shrinkage.
- the obtained cushioning member web was confirmed to have improved hardness by the effect of being compacted by the needle punching process. The durability was confirmed.
- the present invention is made of a fibrous substrate mixed with a binder fiber in a PCT material having excellent heat resistance, chemical resistance, elasticity and bulkiness compared to PET material fibers, or the fibrous substrate is at least two layers interlayer A cushion member for automobile interior having a multi-layer structure having a spacer fabric inserted therein was provided.
- the cushion member of the present invention is suitable for automobile interior use by satisfying light weight and high elastic recovery rate due to the higher heat resistance, chemical resistance, elastic force and bulkiness of the PCT material fibers adopted by the material change of the fibrous substrate. .
- interior cushion members such as railway vehicles, ships, aircrafts, cushion members for interior furniture.
