Example 2:
a thermal spray bonded cotton is shown in figures 1-7, and during production, the glue spraying device is adopted in the glue spraying link for production.
In order to ensure the warming effect; the raw materials of the thermal glue-spraying cotton adopt 4080 low-melting-point polyester fiber, polyester staple fiber and superfine fiber; wherein the percentage of the superfine fiber accounts for 25-45% of the total mass of the raw materials, even 30%.
In order to improve the product quality; as shown in FIG. 7, when the thermal spray cotton is sprayed with glue, the suction force in the U-shaped tube 14 is controlled to be 1.5-3.5 MPa, even 2 MPa.
Experiment one:
in order to guarantee the heat preservation effect and the product performance, under the condition that other conditions are not changed, the proportion of the superfine fibers in the raw materials is changed, production is carried out, and heat preservation test is carried out after production to obtain the following data.
From the above, when the superfine fiber addition ratio accounts for 30-45% of the total proportion of the raw materials, the thermal insulation capability of the glue-sprayed cotton is excellent, and when the superfine fiber addition ratio is 25-30%, the bonding effect of the product is better, so that the superfine fiber addition ratio is preferably 30%.
Experiment two:
in order to ensure the spreading effect of the glue when spraying the glue, under the condition that the other conditions are not changed, the suction force in the U-shaped tube 14 is adjusted, and multiple production is performed, as shown in fig. 7, the following data are obtained:
| suction in U-shaped tube | 1.5Mpa | 2Mpa | 2.5Mpa | 3Mpa | 3.5Mpa |
| Degree of volume shrinkage of spray bonded cotton | 9.8% | 10.3% | 11.5% | 14.2% | 16.7% |
| Diffusion effect of glue | Good effect | Is excellent in | Is excellent in | Is excellent in | Is excellent in |
As can be seen from the above, when the suction force in the U-shaped pipe 14 is controlled to be 2 to 3.5Mpa, the glue spreading effect is excellent, and the suction force in the U-shaped pipe 14 also affects the volume shrinkage degree of the sprayed cotton, which increases with the increase of the suction force in the U-shaped pipe 14, so the suction force in the U-shaped pipe 14 is preferably controlled to be 2 Mpa.
