荣昌猪鬃几项理化性状的测试

THE STUDY ON SOME PHYSlCAL AND CHEMlCALFUNCTION OF PIG'S BRISTLES

当今世界，塑料、化纤制品日新月异，猪鬃是否已失去其应用、开发价值，是尚有争议的问题。作者对５７头荣昌成年、后备母猪，长白成年、后备母猪的１２５５根鬃样与２４５根聚丙烯单丝样的几项理化性状测试结果表明：荣昌猪鬃在长度、直径、弹性、强度、鳞片层５方面优于长白猪鬃；弹性和耐热性能优于聚丙烯单丝，荣昌成年猪鬃强度优于聚丙烯单丝，荣昌猪鬃有鳞片、尖梢分岔，聚丙烯单丝无鳞片、无尖梢、不分岔。所测性状，荣昌猪鬃不仅多数指标优于长白猪鬃，而且具有聚丙烯单丝某些难以比拟的特性，因此，在军工、耐热、油漆化工等高档制刷领域，荣昌猪鬃仍不失为首选原料。

Nowadays, plastic and chemistry fiber Products is changing every day, wheatherthe bristles have lost its developing values is a question. The authors studied 4255 brist-les samples taken from 57 Rongchang sows, gilts and Landrace sows gilts. The resultsshowed that Rongchang bristles were superior to bristles of Landrace in the followingfive respects: namely length, diameter, elasticity, strength and scale layers; In respectof elasticity and heat resistance, Rongchang bristles obviously surpassed polyacrific fi-ber, but only the adult's bristles were slightly stronger than Polyacrific fiber. Rongcha-ng bristles possessed scales and top branches but polyacrific did not. Above all, Rongch-ang bristles are not only superior to Landrace bristles in most indexes, but also poss-ess some excellent properties to which Polyacrific fiber can hardly compare. So theyare still now widely .used in defence forces, painting, chemistry industry and othersbigh tecbnology fields.
