摘要： A process is provided for the continuous production of a high-strength and high-modulus polyethylene material having excellent properties. According to the process, powder composed of ultra-high-molecular-weight polyethylene powder as a principal component is subjected to compression molding, rolling and stretching. The polyethylene powder has an intrinsic viscosity of 5-50 dl/g as measured at 135.degree. C. in decalin. The compression molding is carried out by feeding the polyethylene powder between endless belts arranged in an opposing up-and-down relation, and conveying the polyethylene powder while holding the same between the endless belts and at the same time, continuously compression molding the polyethylene powder at a temperature lower than its melting point by a compressing means provided inside of the endless belts. In at least one of the compression molding step and rolling step, an olefin polymer having a molecular weight lower than the polyolefin polymer is concurrently processed.

摘要： A non-woven fabric having a strength which is comparable to the strength of woven fabric and a method of making such non-woven fabric are disclosed. The non-woven fabric has a laminated structure composed of a warp web of random-laid non-woven fabric stretched lengthwise and hence having a greater strength in the lengthwise direction than in the transverse direction, and a weft web of random-laid non-woven fabric stretched transversely and hence having a greater strength in the transverse direction than in the lengthwise direction. Filaments constituting each of the warp and weft webs are substantially free from molecular orientation and extendible at least two times the original length before the web is stretched. Upon stretching of the web, the un-oriented filaments are substantially stretched to thereby cause molecular orientation therein.
