It is found that bamboo fiber knitted fabric of different stitches is of good airporosity and crease-resisting and of soft, but prone to balling up.
认为各种组织的竹纤维针织物都具有良好的透气性和抗皱性，织物柔软性较好，但抗起毛起球较差。

And analyzes the reason and forming mechanism of the defects such as cold crack, airporosity and oxidation etc. proposes the measures of welding process to ensure the welding quality.
The obtained wall material has the characteristics of big airporosity, small heat conductivity and high compression strength, and realizes the light heat insulation of the wall material.
