Continuous Fabric Washing Machine with Enhanced Efficacy
Here’s PatSnap Eureka !
Summary
Problems
Existing machines for continuous washing of fabrics in rope form face challenges with short dwell times in wash baths, leading to inferior wash performance and increased risk of fabric damage due to inadequate washing efficacy and productivity.
Innovation solutions
A machine design featuring multiple wash tanks with transit ducts that allow for alternate movement of fabric between tanks, where wash water flows in the opposite direction to fabric movement, ensuring effective washing and reducing fabric damage through balanced tensile and opposing forces, and utilizing pivoting transit ducts with sensors for controlled reversal of fabric direction.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the advance speed of the fabric is increased to improve productivity, then the productivity is improved, but the dwell time of the fabric in wash baths becomes very short, reducing wash quality
Why choose this principle:
The washing machine is divided into multiple independent wash tanks (first wash tank, second wash tank, third wash tank) connected in series. The fabric sequentially passes through each tank, accumulating in each tank before moving to the next. This segmentation allows the fabric to receive cumulative washing action across multiple tanks while maintaining high advance speed between tanks, thereby improving both productivity and wash quality.
Principle concept:
If a single wash bath is used to simplify the machine structure, then the device complexity is reduced, but the dwell time is insufficient and wash performance deteriorates
Why choose this principle:
Multiple wash tanks are merged into a single continuous washing system where the fabric passes through each tank in sequence. The tanks work together as an integrated system, with the fabric accumulating and being washed in each tank before moving to the next. This merging approach achieves superior wash performance through cumulative washing action while maintaining a relatively simple overall structure compared to complex multi-pass systems.

Abstract
A machine for continuous washing of fabric in rope form, comprising two or more wash tanks (11, 12), including an initial wash tank (11) in which the fabric (T) is designed to enter at a first speed (V1) and a final wash tank (12) from which the fabric is designed to exit at the same said first speed (V1), fabric being accumulable in said wash tanks. The machine also comprises means for alternate movement (19) of the fabric between at least two consecutive wash tanks (11, 12) with a second movement speed (V2), greater with respect to said first speed (V1), in such a manner as to alternately accumulate fabric in said two consecutive wash tanks (11, 12)..
