Problems solved by technology

[0004] Traditional blended spinning can only provide evenly distributed two-component or multi-component yarns. Not only is the carding and mixing process of the previous spinning difficult and the production rate is low; it is also unable to show the appearance effect of the concentrated component fibers combined.

Abstract

The present invention relates to a kind of porous flared feeder for ring spinning and its making process and use. The porous flared feeder of fiber sliver feeder has 2-7 inlet and outlet hole canals, and has several fiber sliver outlet or single fiber sliver outlet with multiple tow converging unit. The feeder is formed through injection molding or injection molding and heat treatment to bend. It may be sued in converging several kinds of tow for composite spinning in various ring spinning machine. The present invention has simple mechanism, low manufacture cost, convenient installation and use and high applicability in composite spinning.

Description

Technical field: [0001] The invention relates to the compact composite spinning technology in the field of textile fiber composite spinning, in particular to a multi-hole bell mouth feeder used on a ring spinning machine. Background technique: [0002] Composite spinning technology is a matter of more than 20 years. It is mainly researched and industrialized by scientists from the Australian Commonwealth Academy of Sciences (CSIRO) Wool Textile Research Institute (DWT) (Lappage, James, AMethod and Apparatus for Producing a Uniform Yam, C SIRO , AU Patent No.438072, 1971; Plate, D.E.A. and Feehan, JD., Improved Method for the Manufacture of Twisted and Plied Yam, CSIRO, AU Patent No.473153, 1974; Sirospun: Goodbye to Two-Fold?, Textile Horizons, Vol .2, No.2, 1982, pp.34-37; Prins, M.W., Lamb, P.R., Naylor, G.R.S., Tao, X., Yarn spinning from fiber sub-assemblies with variants of their paths of travel, relative positions ortwist levels, US Patent No.6012277,2000), its typica...
