The present invention provides a super soft neoprene foam rubber fabric manufacturing method comprising: a foaming composition manufacturing step of adding 0.5 to 2.0 parts by weight of a sulfur crosslinking agent, 0.2 to 1.0 part by weight of a crosslinking accelerator, 10 to 50 parts by weight of paraffin oil, 2 to 10 parts by weight of magnesium oxide, 2 to 10 parts by weight of zinc oxide, 10 to 40 parts by weight of clay, 10 to 40 parts by weight of carbon black, and 10 to 15 parts by weight of a mixed foaming agent based on 100 parts by weight of chloroprene and sufficiently kneading and mixing the same; a neoprene foam sheet manufacturing step of inputting the composition for foaming into a press and crosslinking and foaming the same at 130 to 175 ℃ for 15 to 30 minutes; and a skiving step of laminating the neoprene foam sheet with an adhesive sheet and thinly cutting the neoprene foam sheet laminated with the adhesive sheet into a plate-shaped fabric having a thickness of 1 mm or less using a rotating blade while supplying the neoprene foam sheet between compression rolls, and a neoprene foam rubber fabric manufactured by the method usefully used for manufacturing wet suits or buoyancy swimsuits. 본 발명은 클로로프렌 100중량부에 대하여 황 가교제 0.5 내지 2.0중량부, 가교 촉진제 0.2 내지 1.0중량부, 파라핀 오일 10 내지 50중량부, 산화마그네슘 2 내지 10중량부, 산화아연 2 내지 10중량부, 클레이 10 내지 40중량부, 카본블랙 10 내지 40중량부, 혼합 발포제 10 내지 15중량부를 첨가하여 충분히 혼련시켜 혼합하는 발포용 조성물 제조단계와; 상기 발포용 조성물을 프레스에 투입하여 130~175℃, 15~30분 조건에서 가교 및 발포시키는 네오프렌 발포시트 제조단계; 및 상기 네오프렌 발포시트를 점착시트와 합지시키고, 상기 점착시트와 합지된 네오프렌 발포시트를 압축롤 사이로 공급하면서 회전칼날을 이용하여 두께 1mm 이하의 판상 원단으로 얇게 절단한 다음, 상기 절단된 원단에서 점착시트를 분리하여 네오프렌 발포고무 원단을 제조하는 스카이빙 단계;를 포함하는 것을 특징으로 하는 초연질 네오프렌 발포고무 원단 제조방법과 그 방법에 의해 제조된 것으로서 웨트 슈트나 부력 수영복 제조에 유용하게 사용될 수 있는 네오프렌 발포고무 원단을 제공한다.
