The present invention provides (1) an endotoxin detoxifying material comprising a fibrous carrier to which Polymyxin is fixed, (2) an endotoxin detoxifying material comprising a carrier to which Polymyxin and a basic nitrogen atom are fixed, and (3) a method of removing endotoxin from a fluid by contacting the fluid with the endotoxin detoxifying material comprising a carrier to which Polymyxin is fixed. The present invention makes it possible to contact blood with Polymixin directly and safely and gives a new method of therapy endotoxemia or prophylaxis of endotoxemia.

Endotoxin detoxifying process

A potentially bulky, processed yarn which is a substantially non-interlaced multifilament yarn of a thermoplastic synthetic fiber satisfying the characteristic values of R.sub.max /R.ltoreq.2.5, .DELTA.S.sub.5 .gtoreq.1.5, .DELTA.S.sub.50 .ltoreq.3.0, Y.gtoreq.1.3 and X.sub.T --X.ltoreq.1.0, where R.sub.max is maximum tension fluctuation width, R is average tension fluctuation width of a normal portion, .DELTA.S.sub.5 is difference in maximum shrinkage among each filament of a sample having a length of 5 cm, .DELTA.S.sub.50 is difference in maximum shrinkage among each filament of a sample having a length of 50 cm, X.sub.T is maximum tension, X is average tension and Y is degree of bulkiness/dry heat shrinkage. A bulky, processed yarn is obtained by supplying a substantially non-twisted thermoplastic multifilament yarn to a heated body under a tension of 10-120 mg/d with monofilaments contacting said heated body at an imaginary point of contact and monofilaments not contacting said heated body at said imaginary point of contact, at the same time contacting said yarn with said heated body within such a short period of time that the heat of said heated body may not uniformly be conducted to the multifilament yarn, and either immediately thereafter winding the yarn, or in the alternative not winding said yarn immediately thereafter, but contacting said yarn with another heated body under conditions not substantially elongating the yarn, thereby eliminating produced loops, and thereafter winding said yarn.

Potentially bulky yarn

A process for producing a potentially bulky yarn which is a substantially non-interlaced multifilament yarn of a thermoplastic synthetic fiber satisfying the characteristic values of R.sub.max /R.ltoreq.2.5, .DELTA.S.sub.5 .gtoreq.1.5, .DELTA.S.sub.50 .ltoreq.3.0, Y.gtoreq.1.3 and X.sub.T -X.ltoreq.1.0, where R.sub.max is maximum tension fluctuation width, R is average tension fluctuation width of a normal portion, .DELTA.S.sub.5 is difference in maximum shrinkage among each filament of a sample having a length of 5 cm, .DELTA.S.sub.50 is difference in maximum shrinkage among each filament of a sample having a length of 50 cm, X.sub.T is maximum tension, X is average tension and Y is degree of bulkiness/dry heat shrinkage.
