The textile industry is considered a major industry worldwide, and some countries use available domestic raw materials for textile manufacturing, being one of many other economic resources. Meanwhile, the Kingdom of Saudi Arabia is at the forefront of States paying great attention to the cultivation of palm trees due to their great importance, which are an indispensable traditional food for a large portion of the population. However, huge quantities of palm’s by-products, especially palm fibers, are constantly wasted, although they can be effectively used to produce textiles of particular end uses such as ropes. This study, therefore, sought to explore the potential of extracting cellulose from palm fibers for use in the textile industry. The study has utilized the experimental approach by applying alkaline to palm fibers so as to extract inherent cellulose. It has also applied mechanical processing to turn cellulose into fibers. Fibers’ physical properties (color, diameter, length), chemical properties (ratios of cellulose, hemicellulose, and lignin), and mechanical properties (tensile strength and elongation of fibers before and after treatment) were all studied. The study has proved that the physical, chemical and mechanical properties of regenerated cellulose fibers extracted from palm fibers are similar to those of other natural fibers such as bamboo and linen, and thus can be used in the textile industry. The study also compared different types of palm trees to determine the one that contains the largest concentration of cellulose. However, it was found that sugar palm fibers contain the highest cellulose concentration of 44% and therefore, it was selected for the application of the study’s theory. The study recommends making use of palm fiber in manufacturing textiles for particular end uses such as ropes, fillings and filters, as well as applying the theory of the study to other plants that have not yet been manipulated.

In order to examine the application of different soil and foliar organic fertilizers as well as biofertilizing flax under sandy soil conditions, two field experiments were carried out at the Research and Production Station of the National Research Centre (NRC), Al Nubaria district, El-Behaira Governorate, Egypt during 2012/2013 and 2013/2014 winter seasons. The trials aimed to study the effect of humic acid (HA) as low cost natural fertilizer, inoculation with mycorrhiza, and biocharcoal on on yield, quality and water use efficiency of flax variety (Amon) under newly reclaimed sandy soil. The treatments consisted of HA (25 kg/feddan), inoculation with mycorrhiza (1 kg/ feddan), and biochar (4 tons/feddan) and all the combinations among the treatments. Results showed that the treatment combination of (humic acid + mycorrhiza + biochar) was significantly superior compared to all the other treatments in number of capsules/plant, biological yield/plant (g), seed yield/plant (g), seed yield (kg/feddan), straw yield (tons/feddan), oil percent (%), and oil yield (kg/feddan). However, it gave the highest fruiting zone length (cm) but not significantly different from (mycorrhiza + biochar) and (humic acid + biochar), also it gave the highest seed index (g) but not significantly different from humic acid and (humic acid + mycorrhiza). The treatment combination of (humic acid + biochar) gave the highest plant height (cm), technical stem length (cm), and number of branches/plant.
