margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important; outline: none 0px !important;"></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; line-height: 1.75em; overflow-wrap: break-word !important; outline: none 0px !important;"><span style="max-inline-size: 100%; margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　(1)改进产品的使用性能。如提高织物的强力或耐磨性能，改善织物的透气性或穿着的舒适性等。如过去长期生产的半线府绸，其经纱特数为14tex×2，纬纱特数为17tex，经、纬密度为346根／10cm×259．5根／10cm，该品种在穿着过程中，发现总是纬向先破损。经分析，知其经向断裂强度为735N(75kg)，但纬向断裂强度仅304N (31kg)，纬向的断裂强度比经向小得多，说明该品种是由于经纬向纱特数及密度配置不当，而造成纬向先断裂。经研究认为，该产品既要克服上述存在的问题，又要使产品风格达到粒纹清晰、布面匀整的府绸织物的特点，必须改进经纬纱特数的配合，即将纬纱改用21tex。</span></p><p style="max-inline-size: 100%; margin-bottom: 0px; clear: both; min-height: 1em; cursor: text; overflow-wrap: break-word !important; outline: none 0px !important;"><br style="max-inline-size: 100%; margin: 0px; padding: 0px; overflow-wrap: break-word !important;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　经改进后的半线府绸因纬纱加粗，粒纹更加清晰，纬向断裂强度达到372N(38kg)，提高了织物的服用性能。调整后的产品规格为：经、纬纱特数为14tex×2×21tex，经、纬密度为346根／10cm × 236 根／10cm。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　又如，巴里纱织物，巴里纱是用强捻纱织制而成的薄型、稀疏、透孔的平纹织物。这类织物虽然密度稀疏，但因经纬纱采用强捻纱，故织物的身骨仍较挺括，手感爽滑，弹性亦佳。使用纯棉原料，其经纬纱大都经过精梳工艺，因而纱身毛羽较少；又因密度稀疏，从而布孔清晰，透气性较好。因此，巴里纱织物具有质地轻薄、手感挺、布孔清晰、透明度好、透气性佳、富有弹性、穿着凉快的风格特征。如把纯棉的原料改用为涤棉混纺纱织制巴里纱织物。这种织物除了上述一般巴里纱的风格特征外，还具有不易折皱、弹性好以及手感挺爽的特点。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　(2)改善织物的外观与风格，丰富产品类型，扩大使用范围。例如，由中厚织物发展为轻薄型织物，形成系列产品。或者使仿丝绸、仿毛织物的风格更加逼真。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　(3)改进生产工艺，缩短流程，合理使用原料，提高生产效率，降低成本等。</span></p><p style="max-inline-size: 100%;

margin: 0px; padding: 0px; cursor: text; font-size: 15px; overflow-wrap: break-word !important; outline: none 0px !important;">　　例如，某丝织物(富春纺)，经丝组合为(33．3dtex涤纶8捻／cm×2)6捻/cm；纬丝组合为(13．4tex×1)涤／粘纱。改进后经丝用74．8dtex涤丝8捻／cm；纬丝改用14．8tex×1涤／粘纱，织成织物与样品风格相近，但简化了并捻工序，降低了成本。</span></p><p style="max-inline-size: 100%;
