Description

폴리프로필렌봉사의 제조방법Method of manufacturing polypropylene thread

본 발명은 합연된 폴리프로필렌 봉사의 제조방법에 관한 것으로서, 내열성이 높고, 고속미싱에서 사용이 가능하며, 방수효과가 좋고, 인장강도가 큰 공업용 폴리프로필렌합연봉사를 제공하고자 하는 것이다. 종래의 봉사로서 면봉사, 폴리에스터봉사, 면/폴리에스터봉사, 나이론 봉사등은 피복류등에만 주로 사용되는 것이었고, 일반 공업용인 가방, 텐트, 제화용등의 봉사로서는 폴리프로필렌봉사를 사용하기는 하였으나, 합연된 봉사가 아니고 필라멘트가 다수개 집속된 단사로서만 사용되어 왔다.The present invention relates to a method for producing a polypropylene polypropylene service, and to provide an industrial polypropylene composite sewing thread having high heat resistance, can be used in high-speed sewing, good waterproof effect, and high tensile strength. As a conventional service, cotton service, polyester service, cotton / polyester service, and nylon service are mainly used only for clothing, and polypropylene service is not used for service of general industrial bags, tents, shoes, etc. However, it has been used only as a single yarn in which a plurality of filaments are focused, not a combined service.

특히 폴리프로필렌 단사 봉사는 사용상의 번거로움이 있으며, 고속미싱에서 사용이 불가능하고, 방수효과가 적으며, 인장강도도 약하여 절단이 잘되는 결점이 있었다.In particular, polypropylene single yarn service has the disadvantage of being troublesome in use, it is impossible to use in high speed sewing machine, has a low waterproofing effect, and has a weak tensile strength, thus making it easy to cut.

본 발명은 상기와 같은 결점을 해소하기 위한 것으로서, 종래에 없던 합연된 폴리프로필렌봉사를 제조하기 위한 방법이며, 폴리프로필렌 용율액과 염료를 혼합한 후 공지의 방법으로 용융방사하고, 콘에 권사하여 단사를 연사하고 다시 2∼3개의 단사를 합사 연사하여 왁스처리하여 다시 콘에 권사함으로써 폴리프로필렌봉사의 제조가 완료되는 것이다.The present invention is to solve the above-mentioned drawbacks, and is a method for producing a conventional polypropylene yarn, which is conventionally melted and spun by a known method after mixing the polypropylene solution and dye, wound on the cone The single yarn is twisted, then two or three single yarns are twisted and twisted, waxed, and wound on a cone again to complete the production of polypropylene yarns.

이하, 본 발명 방법을 상세히 설명하면 다음과 같다. 공지의 방법으로 폴리프로필렌사를 용융망사하기 위하여 폴리프로필렌용융액과 염료를 중량비 100 : 6으로 혼합하여 200℃∼230℃로 용융 방사한다. 이때 필라멘트 36개를 300데니어의 단사로 하며, 인장 강도는 3.8g/D∼4.2g/D로 방사한다. 방사된 300데니어의 단사를 콘데 10,000m 단위로 권사하게 된다.Hereinafter, the method of the present invention will be described in detail. In order to melt mesh polypropylene yarn by a known method, a polypropylene melt and a dye are mixed in a weight ratio of 100: 6 and melt spun at 200 캜 to 230 캜. At this time, 36 filaments are single yarn of 300 denier, and the tensile strength is spun at 3.8 g / D to 4.2 g / D. The single yarn of 300 denier spun will be wound in conde 10,000m increments.

이와 같이 된 단사를 꼬임수 600/m로 연사하고 연사된 단사 2∼3개를 다시 꼬임수 400∼450/m로 합사하여 연사한다.The single yarn thus obtained is twisted at a twist rate of 600 / m, and 2-3 twisted twisted yarns are again twisted and twisted at a twist rate of 400 to 450 / m.

그런데, 폴리에스터사를 선염하고자 하는 경우에는 상기와 같이 용융방사전에 염료를 함께 혼합하며, 후염하고자 할때는 합사시에 콘에 합사하지 않고 타래에 합사하여 염색하게 된다. 이와 같이 선염 또는 후염되어 합사된 봉사는 왁스나 오일처리를 받게 되는데, 고체상 파라핀을 관통시키면서 왁스처리를 하는 것이 효과적이다. 왁스처리된 봉사는 콘당 5,000m로 권사되어 폴리프로필렌봉사가 완료되는 것이다.By the way, if you want to dye the polyester yarn, the dye is mixed together before the melt spinning as described above, and when you want to dye after dyeing by splicing in the skein without spun in cone at the time of weaving. In this way, the pre- or post-dyed serviced yarn is subjected to wax or oil treatment, and wax treatment is effective while penetrating solid paraffin. The waxed service is wound at 5,000 meters per cone to complete the polypropylene service.

이와 같이 본 발명 방법에 의하여 제조된 폴리프로필렌봉사는 인장 강도가 높아 생산중이나 사용중에 절단이 되지 않아 생산속도 및 생산능률이 높고, 가격에 있어 일반 봉사보다 저렴하여 경제적이며, 꼬임을 주었으므로 필라멘트 상태의 봉사보다 재봉기의 바늘 구멍과 마찰면적이 작아 작업중 열의 상승이 적어 재봉유가 필요 없으며, 선염 또는 후염을 선택할 수 있어 제조공정이 간편하고, 필라멘트 단섬유 봉사보다 조직이 치밀하여 방수효과가 큰 등의 효과가 있는 것이다.Thus, the polypropylene yarn produced by the method of the present invention has a high tensile strength, so that it is not cut during production or use, and thus the production speed and production efficiency are high, and it is cheaper than general service in terms of price, and it is economical because it is twisted. The needle hole of the sewing machine and the friction area is smaller than that of the service, so there is no need for sewing oil due to less heat rise during operation. It works.

본 발명의 실시예를 보면 다음과 같다.An embodiment of the present invention is as follows.

[실시예 1]Example 1

폴리프로필렌 용융액 250kg과 염료 15kg을 혼합하여 230℃에서 용융방사하였다. 이때 필라멘트 갯수를 36으로 300데니어 단사로 하여 인장강도는 4.0g/D로 방사하였다. 단사를 콘당 10,000/m되게 권사한 후 꼬임수 600/m되게 연사하고, 단사 2개를 합사하여 다시 꼬임수 400/m로 연사하였다. 그후, 고체상태의 왁스를 관통시키면서 왁스 처리한 후 콘당 5,000m로 권사하였다.250 kg of polypropylene melt and 15 kg of dye were mixed and melt spun at 230 ° C. At this time, the number of filaments was 36 denier to 300 denier single yarn, and the tensile strength was spun at 4.0 g / D. The single yarn was wound to 10,000 / m per cone and then twisted to 600 / m twist, and the two single yarns were spliced and twisted to 400 / m twisted again. Thereafter, waxing was carried out while penetrating the solid wax, followed by winding at 5,000 m per cone.

[실시예 2]Example 2

폴리프로필렌 250kg을 실시예 1과 같이 합사하되 타래로 합사하여 염료 15kg으로 후염한다. 후염 한 후 동일한 왁스처리를 거쳐 권사하였다.250 kg of polypropylene is spun together as in Example 1, but spun together with sprinkled with 15 kg of dye. After dyeing, it was wound through the same wax treatment.

[실험예]Experimental Example

본 발명 방법에 의하여 제조된 폴리프로필렌봉사를 일반 봉사와 비교하여 인장강도를 시험한 결과표는 다음과 같다.The results of testing the tensile strength of the polypropylene yarn prepared by the method of the present invention compared to the general service is as follows.

상기와 같이 본 발명에 의한 폴리프로필렌 봉사는 인장강도에 있어 일반 봉사보다도 큰 것을 알 수가 있다.As described above, it can be seen that the polypropylene service according to the present invention is larger than the general service in tensile strength.
