When the angle B of the air blown by the air blowing pipe, which is obliquely blown upwards to the yarn fabric, is larger than 150 degrees, if the value H2 of the air flow transmittance L1 divided by the air flow upper reflectivity L2 is larger than or equal to a set value 10A, and meanwhile, if the value H1 of the air flow upper reflectivity L2 divided by the air flow lower reflectivity L3 is smaller than or equal to a set value 15A, judging that the yarn fabric is qualified in air permeability, otherwise, judging that the yarn fabric is not qualified in air permeability.
The air flow entering the first air receiving port, the second air receiving port and the third air receiving port can be easily detected through the air speed sensor. The air flow detected by each air speed sensor is compared or calculated with the preset values among the air flow speeds of the first air receiving port, the second air receiving port and the third air receiving port, so that whether the air permeability of the yarn fabric is qualified can be judged more quickly. The method for controlling the air permeability of the yarn fabric is simple and has high reliability.
The tension J1 at the lower end of the yarn fabric can be calculated through the height sensor.
When the air blowing pipe blows air to the left side of the yarn fabric 14, the yarn fabric protrudes to the right, the protruding yarn fabric can block the laser lamp from shining to the photoelectric sensor, and the protruding length K1 of the yarn fabric to the right can be obtained according to the size of the optical signal value H detected by the photoelectric sensor. The yarn fabric bulges to the right because the air blowing pipe blows air to the left side of the yarn fabric. The air speed of the air blowing pipe for blowing air to the left side of the yarn fabric is set to be V1. When J1 is constant, the larger the value of V1 is, the larger the value of K1 is, the more light is blocked, and the smaller the light detected by the photosensor is.
Because V1 and J1 can be preset, under the condition that V1 and J1 are set values, the value of K1 can reflect the pit depth of the left surface of the yarn fabric; the deeper the pit depth, the larger the gap between the spinning threads of the yarn fabric positioned at the pit is, so that more wind blown into the pit can enter the first air receiving port through the yarn fabric. If the values of K1 are within the set values under the condition that V1 and J1 are both set values, and the air flow penetration rate L1 is within the preset air flow penetration rate range, the air permeability of the yarn fabric is qualified, and otherwise, the air permeability of the yarn fabric is unqualified.
The rotating shaft of the horizontal rotating motor can drive the air blowing pipe, the second air receiving port and the third air receiving port to rotate together in the same horizontal plane, so that the angles among the air blowing pipe, the second air receiving port, the third air receiving port and the yarn fabric are easy to control.

the method comprises the steps of detecting the air permeability of yarn fabric, and simultaneously starting a heat emitting end of a heating mechanism to emit heat to perform heating and heat insulation detection on the yarn fabric positioned in a heating and heat insulation detection area; if the heat detection mechanism detects that the heat transmitted from the side of the yarn fabric is within the design range, judging that the heat preservation property of the yarn fabric is qualified, otherwise, judging that the heat preservation property of the yarn fabric is unqualified;
and judging the yarn fabric with qualified air permeability and heat preservation as a qualified yarn fabric product.
When the air permeability of the yarn fabric is detected, the yarn fabric is tensioned through a gravity rolling shaft, so that a detection area of the yarn fabric is in a vertical plane; at this time, the yarn fabric is positioned between the air blowing pipe and the first air receiving opening.
Then under the control of the microcontroller, the air blowing pipe of the air blowing mechanism blows the yarn fabric positioned in the air blowing ventilation detection area, the first air receiving port, the second air receiving port and the third air receiving port of the air flow detection mechanism collect air blown out by the air blowing pipe respectively, and the air flow rate of the collected air is detected by the air flow detection mechanism; determining whether the air permeability of the yarn fabric is qualified or not according to the detected air flow rate; if the detected gas flow rate is within the set value range, judging that the air permeability of the yarn fabric is qualified, otherwise, judging that the air permeability of the yarn fabric is unqualified;
the method comprises the steps of detecting the air permeability of yarn fabric, and simultaneously starting a heat emitting end of a heating mechanism to emit heat to perform heating and heat insulation detection on the yarn fabric positioned in a heating and heat insulation detection area; if the heat detection mechanism detects that the heat transmitted from the yarn fabric side is within the set value range, judging that the heat preservation property of the yarn fabric is qualified, otherwise, judging that the heat preservation property of the yarn fabric is unqualified; and judging the yarn fabric with qualified air permeability and heat preservation as a qualified yarn fabric product. And then warehousing the qualified yarn fabric product.
And the yarn fabric is fed into a drying cavity of the yarn fabric steam drying device body for drying. And the upper steam pressing plate can extrude the upper steam on the upper surface of the yarn fabric, so that the contact time of the upper steam and the yarn fabric is long, when the upper steam reaches the upper steam discharge pipe, the upper steam is discharged by the corresponding upper steam discharge pipe, and similarly, the lower steam pressing plate can extrude the lower steam on the lower surface of the yarn fabric, so that the contact time of the lower steam and the yarn fabric is long, and when the lower steam reaches the lower steam discharge pipe, the lower steam is discharged by the corresponding lower steam discharge pipe.
Because the lower steam input port of the lower steam input pipe and the upper steam input port of the upper steam input pipe are arranged vertically and oppositely, the yarn fabric can be kept to advance on the horizontal plane, and the drying effect of the yarn fabric is good.
