   كثيرًا ما تُستخدم الخصائص  الميكانيكية لتحديد الوظائف المرادة من الأقمشة المنسوجه ،حيث تعتبر قوة التمزق أحد  أهم معايير تقييم العمر الإستهلاكى للأقمشة خاصة أثناء الإستخدام اليومى .و يصف الباحث في هذا العمل بالتفصيل قوة التمزق ومسار الشق التى تتعرض له الأقمشة القطنية المنتجة بثلاثة اساليب غزل  القطن المختلفة من (المسرح- الممشط – الطرف المفتوح ). حيث أن طرق القياس المعملية وعلاقات الارتباط بين النتائج التي تم الحصول عليها من زوايا القطع المختلفة لمعظم الأقمشة القطنية الشائعة في الأسواق المصرية إستخدم فيها  طريقة تمزق اللسان، بالإضافة إلى ذلك ، تم قياس قوة التمزق فى الزاويا المختلفة من القطع للعينات محل الدراسة  مع الأخذ فى الاعتبار التراكيب النسجية المستخدمة من  ( السادة – المبرد – الأطلس )، وتم حساب معاملات الارتباط بين الخصائص المختلفة لكل عينة ومقدار مقاومتها لقوة التمزق ، حيث  أظهرت النتائج ان هناك علاقة معنوية ذات الصلة بخصائص الاقمشة محل الدراسة تباعا للمنهجية المستخدمة من حيث  نوع الغزل المستخدم والتركيب النسجى وكذلك مقدار زاوية الشق لتمزق العينة وذلك بدلالة إحصائية (0.0001) لكافة المتغيرات محل الدراسة .
