Description
Technical field
The invention belongs to field of textiles, it is related to a kind of Yarn spinning method, more particularly to a kind of flow-guiding type integrated composite spinning method.
Background technology
In recent years, compact spinning process can significantly improve yarn due to both having the advantages that traditional ring spinning, again and exist
Performance in terms of hairiness number and intensity, by wide popularization and application in field of textiles, compact spinning process is also increasingly ground
Study carefully the concern of personnel.
At present, the method that integrated composite spinning is used is mainly air-flowing type integrated composite spinning, and such as patent CN104131371A is disclosed
A kind of collecting-spinning device, including drafting system and the apparatus for collecting that is arranged on before drafting system, drafting system are at least wrapped
A front roller and the front leather roller tangent with front roller are included, apparatus for collecting includes twisting resistance roller, resistance twist roller, negative-pressure air-suction abnormity
Pipe, air-flow prerotation vane and open-work cushion rubber, twisting resistance roller are arranged on before front roller, and negative-pressure air-suction special pipe is arranged on front roller
Between twisting resistance roller, open-work cushion rubber is set on twisting resistance roller and resistance twist roller is pressed on open-work cushion rubber, negative-pressure air-suction abnormity
It is close on the upside of pipe on open-work cushion rubber, air-flow prerotation vane is arranged between front leather roller and resistance twist roller, though above-mentioned collecting-spinning device
It is so simple in construction, need not change spinning frame, but carry out needing the higher negative-pressure air-flow of pressure during air-flow boundling, just can guarantee that final
The quality of the integrated composite yarn of formation, the energy consumption for carrying out integrated composite spinning is higher.
In order to further reduce energy consumption, the cost of integrated composite spinning is reduced, researcher has carried out substantial amounts of research, but research
Personnel are concentrated mainly on for the improvement of apparatus for collecting changes the shape for gathering groove, and such as patent CN104975385 discloses one
The device for the integrated composite spinning for improving air-breathing slot structure form is planted, air-breathing groove slotted eye axis direction is improved into centre has interruption
Subsection setup, it can make the negative pressure flow of whole agglomeration configure more reasonable, while improving the air-breathing slot structure tool set
There is the self-cleaning function to grid ring, although above-mentioned collecting-spinning device saves the gas for carrying out integrated composite spinning to a certain extent
Stream consumption, improves the spinning effect of compact spinning, but carries out still needing the higher negative-pressure air-flow of pressure during integrated composite spinning, above-mentioned
Improve and do not solve the high shortcoming of compact spinning power consumption inherently.
Therefore, study a kind of pressure of negative-pressure air-flow when can effectively reduce integrated composite spinning and ensure final obtained gather
The flow-guiding type integrated composite spinning method tool of the quality of yarn is of great significance.
The content of the invention
The invention aims to overcome above-mentioned deficiency of the prior art, by installing guiding device in Nesting Zone,
Change speed and the direction for gathering rooved face air current flow, so that negative pressure gas when can effectively reduce integrated composite spinning there is provided one kind
The pressure of stream and the flow-guiding type integrated composite spinning method for ensureing the finally quality of obtained integrated composite yarn.
In order to achieve the above object, the technical solution adopted by the present invention is：
