 Full text | Abstract: This paper presents investigations into the wetting phenomenon of terry fabrics. Terry fabrics were manufactured using linen warp pile yarns. The high absorption ability of terry textile is acquired by increasing the capability of the moisture absorbing surface to retain liquid in its pores and internal pores of the textile material .The full process of liquid absorption was analysed, from the moment the drop falls onto the fabric’s surface until the it is absolutely absorbed by the material, and the spot being changeless. The character of the wetting process depends on the fabric’s characteristics, kind of impact and its lasting period e.g. a macerating impact shortens the absorption process. The wetting process is faster, lasting up to 130 s, in fabrics affected by washing operations. The means of changes in the area of the spot compared with the area at the starting moment are always larger in the case of terry fabrics with bleached warps compared with unbleached ones irrespective of kind of impact and duration. Experimental results are best described by polynomial equations. The determination coefficients of the equations obtained vary from 0.9711 to 0.9969. |
