Natural Cross

SUMMARYThe percentage of natural cross pollination was estimated in the Alexandria area (Egypt) in two sites near and far from an apiary. The Egyptian cotton variety Giza 45 and the glandless strain Bahtim 110, as a marker parent, were used during three growing seasons. The average natural crossing within the square of the marker parent were 3·54 and 0·34% near and far from the apiary respectively. For the plants around the square of pollen source, however, the average of natural crossing was 0·56% near the apiary, while it was 0·21% far from the apiary. The natural crossing steadily decreased as the distance from the marker variety increased.

Cotton leaves have been used to extract natural dye for dyeing of Egyptian cotton variety Giza 86 fabric and its blend with polyester 50:50, using different mordants such as iron (II) sulfate, copper (II) sulfate, and alum. The exhaust dyeing method was utilized using the pre-mordant technique. It is observed that both fabric samples can be dyed in different colors and depth of shades with Cotton leaves dye. Iron (II) sulfate ensures the best light fastness. Improved light fastness is obtained using abovementioned lower amounts of iron (II) sulfate and copper (II) sulfate. Alum is found to be less effective than iron (II) sulfate and copper (II) sulfate on the light fastness. As a novel alternative and potential natural dye, Cotton leaves extract solution can be used to get various colors and shades with satisfactory fastness properties. The mordanted and un-mordanted fabric samples were tested for their dyeing performance in terms of color parameters K/S, (L*), a*, b*, (C*) and (H*), and fastness properties (wash, perspiration, light and rubbing fastness) were studied. The samples showed high color strength, and high fastness properties. These results are very important for industrial application and with the production of a natural dye as an inexpensive source from cotton leaves as a by-product. Another objective is to increase the production of eco-textile garments with a good price for the Egyptian customers.

The purpose of the current study is to characterize Egyptian cotton using HVI and CCS measurements. The present investigation was carried out at two different locations: The Global Center for Cotton Testing Research in International Cotton Association (ICA) using HVI instrument in Germany and Egyptian and International Cotton Classification Center (EICCC), Cotton Research Institute (CRI), Agricultural Research Center (ARC) using CCS instrument in Egypt. Samples are sourced from standardized preparation stages to obtain more homogeneity. All samples were collected from 2018 and 2019 cotton growing seasons. The studied cotton fiber properties: upper half mean (UHM), uniformity index (UI %), short fiber index (SFI %), strength (FS) and elongation (E %) and micronaire reading (Mike) and maturity ratio (MR). The studied cotton varieties include long staple cotton varieties i.e., Giza 86 and Giza 95 and extra-long staple cotton varieties i.e., Giza 92 and Giza 93, in terms of basic Egyptian cotton grade Good (G). The results of HVI and CCS measurements were detected by using descriptive statistics such as measures of central tendency and dispersion, skewness, and kurtosis. The CCS measurements were more stable than HVI measurements. Confidence intervals of CCS measurements were close to each other compared to HVI measurements. For instance, in Giza 92, confidence interval of UHM was 32.00-32.32for HVI and 32.50-32.55for CCS, adding to confidence intervals for FS were 45.19-46.83for HVI and 46.99-47.17 for CCS. Meanwhile, confidence intervals for Mike were 3.04–3.21 for HVI and 3.12–3.14 for CCS. Basically, sample sizes of CCS were larger more than sample sizes of HVI so that results of CCS measurements were more homogenous than HVI measurements. Applying reliability analysis for consistent results in CCS and HVI measurements elaborated Cronbach's value were more efficient than using Cronbach's value if item deleted for both CCS and HVI. Cronbach's value of CCS measurements was more than HVI measurements and that due to the homogeneity of CCS samples compared to HVI samples.
