Description
Technical field
The present invention relates to a kind of fiber blend and become net arrangement, especially relate to the pneumatic net arrangement that is blended into of a kind of long and short fiber.
Background technology
After air lay was meant that fiber mixes through shredding, feeding was told and rotating cylinder or licker-in further is carded to filament.Under the synergy of the centrifugal force of cylinder or licker-in and air-flow, fiber comes off from sawtooth then, leans on gas delivery, condenses upon on the lace curtaining (or dust cage), forms fibre web.
For improve the mixed and disorderly degree that fiber is arranged in final fibre web, conveyance conduit structurally often adopts Venturi tube in the air lay.This pipeline is actually a kind of varying-arca channel, and promptly the sectional area in any two cross sections is unequal in the pipeline, and pipeline exports progressively expansion from entering the mouth to.By fluid mechanics principle, gas can be considered incompressible under normal pressure, because sectional area is different; The gas flow rate of various piece is different in the pipe, because fiber has certain-length, in Venturi tube; Its head, tail end is in two different cross sections, so fiber head, tail end speed be different, and head end speed is lower than tail end speed; So fiber produces break-in, form in a jumble and arrange.
Application number is that " a kind of the pneumatic dispersed with stirring of clustered fiber, become net arrangement " application for a patent for invention of 201110206746.4 provides a kind of the pneumatic dispersed with stirring of clustered fiber, become net arrangement; This device uses two taper buckets and the pneumatic mixing chamber of U type to form, and wherein also comprises many group air current spray nozzles and electrostatic atomiser.Cluster shape fiber and ultimate fibre are with static in operation before, get into pneumatic dispersing and mixing chamber from inner cone bucket jet, in mixing chamber, are subjected to stir to cut under the air-flow effect to mix, and under gravity and flow field effect, settle into net subsequently.Because this technology has been used counter-flow jet, electrostatic atomiser uses mixed-powder when stirring.Before stirring also need be static on the fiber band, and fiber could be accomplished mixing and bonding under electrostatic field, and cost is higher.And group's clustered fiber dispersion is relatively poor, and the gained fibre web uniformity is relatively poor, be fit to make sheet material, rather than the flexible non-weaving material.
Therefore, those skilled in the art are badly in need of researching and developing and a kind ofly can be produced the flexible non-weaving cloth material, and fiber blend simple to operate, that cost is low becomes net arrangement.
Summary of the invention
For solving the problems of the technologies described above; The invention provides the pneumatic net arrangement that is blended into of a kind of long and short fiber; This device utilizes and pneumaticly the different fiber of length is fully spread and mixes each other, through adjusting two kinds of proportionings that fiber content is different, improves fiber alignment and fibre net structure in the gained fibre web; Make fibre web have strength property and moisture absorption flow conductivity preferably simultaneously, and simple to operate, cost is low.
