Blowroom Technology
sub-area
The blowroom is the first processing section in a short-staple spinning mill, comprising a sequence of machines arranged in series and connected by transport ducts. Its tasks are to open compressed bale material into fine tufts, eliminate impurities (40–70% removal), remove dust, and provide thorough blending of fibre components, while treating the raw material gently and maximising its utilisation.
Role
The blowroom determines the quality foundation for the entire spinning process. Approximately 50% of all yarn shortcomings, quality-reducing factors, and yarn break causes can be traced back to blowroom and carding operations. Raw material accounts for 50–70% of yarn cost, making efficient blowroom operation critical to profitability.
