ffect of Some Cons
Effect of Some Construction Specifications on Fabric Properties Produced for incontinence pad to Suit Functional Purpose
Abstract
This research is mainly concerned with designing woven fabrics used in diapers. The woven technique was applied to produce these fabrics, using cotton yarns. The produced fabrics were treated with Scouring, Bleaching ,antibacterial ,softening, water repellency, hydrogel or superabsorbent formation by Quat-188, Actigard and carboxy methyl cellulose. Different parameters were studied including, fabric structure (plain weave 1/1, regular hopsack 3/3 honeycomb and mock leno).Their influence on the performance of the end-use fabric and the achieved properties were studied. On the other hand physico-chemical properties including; antibacterial, water repellency, absorption, air permeability, water permeability, handle, 9-tensile strength & elongation, thickness and weight, were evaluated according to the final product needs
-Nappies (diapers)
Nappies (diapers) are used to absorb waste from babies for maintaining health and hygiene of baby as well as his environment .Mothers used to cover the baby with old clean and absorbent cloth.Whenever the diapers get solid ,they are changed ,washed ,dried ,and reused .The types of nappies or diapers vary greatly through out the world from reusable cloth to the modern disposable type. Disposable diapers and similar have been manufactured using one or more layers of cellulose tissue which makes the diaper relatively stiff . Reusable nappy is made from woven terry cloth which is a woven, warp-pile cotton fabric covered on both sides with uncut loops .
The experimental Work
This research concerns with producing fabrics suitable for diapers. All samples in the research were produced with woven, nonwoven and knitted technique.
Results and discussion
Results of the experimental tests carried out on samples under study were presented in tables. Results were also statistically analyzed for the data listed and relationships between variables were obtained.
Antibacterial test
1- Treatment of fabrics with Quat-188 led to improvement in properties of the anti- microbal resistance.
2-bacterial and softening treatment have increased the antibacterial resistance ,we can state that the softening material ,gave the fabric hydrophobicity ,which increased the antibacterial resistance.
3-the cellulous increase the antibacterial resistance, so samples produced with 45 g/m2 have achieved the highest rates of bacteria zone increase.
Bursting resistance
It is clear from the diagrams that cotton samples produced of 195 g/m2 and single jersey structure have achieved the highest rates of bursting resistance , whereas cotton / polyester samples produced of 140 g/m2 and 170 g/m2 and single jersey structure have achieved the lowest rates .
Absorption
From tables and figures ,it is obvious that the increase of Quat-188 concentrations 0 % (which is made of methyl cellulous in cross correlation with methyelene bisacrylamide )gives the highest content of Hydrogel absorption in SRV to 2000 % and WRV to 2500% . Also it is obvious that the carboxy methyl cellulous gives the lowest area of surface of bacterial for both bacterial and fungal activity
Water repellency
From tables, and figures , that samples achieved zero of water repellency before treatment , After treatment the samples achieved high water repellency ,but the effect of fabric structure was insignificant ,
Tensile strength
It is clear from the diagrams and tables that plain weave 1/1 has obtained the highest rates of tensile strength , whereas regular hopsack 3/3 has obtained the lowest rates,.
Bursting resistance
It is clear from the diagrams that cotton samples of 195 g/m2 and single jersey structure has achieved the highest rates of bursting resistance ,
Handle test
After antimicrobial treatment the fabrics smoothness has decreased because the treatment was made using alkali and high temperature ,
Water permeability
From the results it is obvious that samples produced of viscose fiber have achieved the highest rates of water permeability among all produced samples .,.
