【摘要】：装饰织物是装点内部空间，突出室内艺术氛围的有效手段，并以其特有的功能和格调，给人以雅致、温馨的感受，营造恬静、和谐的室内氛围。近年来，随着人们生活水平的逐步提高，其消费心理也在不断改变，各种个性化、创意化、智能化、功能独特的纺织品逐渐成为消费者的主要选择类型。随着产品类型的不断丰富，为了不减弱甚至提高装饰窗帘织物的遮光性这就有必要对装饰窗帘织物的工艺以及材料加以创新和改进。而目前市场上遮光窗帘织物大都采用压花、印花、涂层等对环境污染和能源消耗大的生产加工过程，普通的提花织物的表面虽能显现多样花型，遮光性能却不尽人意，因此研究开发集装饰美观、遮光、环保于一体的高遮光性装饰窗帘织物有重要的现实意义，同时作为成品又具备很强的市场竞争力。本文通过对装饰织物遮光性影响因素的分析论述，为开发新型高遮光性窗帘装饰织物提供一定的理论基础。在此基础上，根据电子提花-多臂复合喷织技术的上机织造原理，分别从织物的组织结构、纬密、纬纱排列比、经纬原料方面入手，有针对性的设计并试制了五大系列共35块双层结构织物，进行相应的性能测试，包括遮光性能和悬垂性能。通过对不同组织结构类型分析，探讨织物组织循环数、组织类型（平纹、斜纹、缎纹）、接结点分布、背衬组织对遮光性的影响规律；通过对不同纬密和纬纱排列比的设置，探讨双层结构纬密及纬纱配比（黑纬）对遮光性的差异影响；通过对FDY丝和DTY丝作为不同经纬原料时进行分析，探讨了原料对于遮光性的影响规律。同时，有针对性的选取三类织物（共14快）进行悬垂性能测试。通过综合性能分析，为高遮光性装饰织物的开发提供一定的技术支持。通过研究分析，可以得出以下几点结论：（1）该新型提花-多臂复合喷水织机的使用，不仅扩大了织物的花幅，增加经密，同时还降低了生产成本，大大提高了产品的市场综合竞争力，为本课题高遮光性装饰产品的开发提供有利的设备支持。（2）相同工艺和经纬密度条件下，不同组织循环数的双层结构织物的遮光性能也不同，随着织物组织循环数增多，单位面积交织点数越少，纱线间的空隙越少，织物的遮光性能越好；相同组织循环数时，织物的遮光性能也各不相同，平均遮光性大小：平纹类组织斜纹类组织缎纹类组织。（3）在织物密度一定且浮长受到有效控制的条件下，，织物组织循环数与织物平均遮光率有着良好的指数关系，随着织物的组织循环数的增加而趋于正比关系，当组织循环数达到一定值后，织物遮光性基本趋于一致，甚至不再变化。（4）在相同工艺和表里层组织条件下，单位面积内随着双层结构接结点数的增多，织物的遮光性能基本保持一致，总体差距较小。即采用接结点分别的设计对于提高织物的遮光性潜力有限，在开发产品时，接结点应以均匀分布，保证表里两层布面平整为主。背衬组织越松，织物的遮光性越好，应选用缎纹类相对较松的组织作为背衬组织，来开发高遮光性装饰织物。（5）当经密为140根/cm时，随着纬密的增大和黑色纬纱比例的增加，织物的遮光性显著提高，且当纬密为96根/cm时，织物遮光率为99.9%，实现全遮光，但织物的手感较硬。考虑实际生产织造和应用情况，高遮光性装饰织物的上机纬密可为72根/cm，纬纱排列比2（黑纬）：1：1。（6）在可见光区域中，相同工艺参数及表里层组织的织物遮光性能：含FDY丝织物含DTY丝织物，FDY丝比DTY丝遮光效果更好。（7）当经密在140根/cm条件下时，纬纱原料、纬密对于织物的悬垂性影响不大，在浮长得到有效控制内，织物组织循环数越大，织物的悬垂性越好。在产品开发时，可根据实际需要选择原料与纬密，优先选用组织循环数大的组织。最后本文结合织物性能测试结果，以经密为140根/cm，纬密为72根/cm，按照2：1：1和1:1两种投纬比例，选用FDY丝为纬纱原料，将其运用于高遮光性窗帘织物的设计开发中，设计出两个系列（6款织物）具有高遮光性的窗帘织物，该系列产品表面富有光泽，质地柔软，遮光性能好，受到广大客户和消费者的一致好评。
[Abstract]:In recent years , with the gradual improvement of people ' s living standards , the consumer psychology has changed gradually , and its consumption psychology has become the main choice type of consumers . Based on the analysis of the influencing factors of the light - shielding property of decorative fabrics , the paper provides a theoretical basis for developing new high - shading curtain decorative fabrics . Based on the analysis of different structure types , the paper discusses the influence rules of weft density and weft ratio ( black weft ) on shading . Through comprehensive performance analysis , some technical support is provided for the development of high - shading decorative fabrics . Through the research and analysis , the following conclusions can be drawn : ( 1 ) The use of the novel jacquard - multi - arm composite water jet loom not only enlarges the flower width of the fabric , increases the warp density , but also reduces the production cost , greatly improves the market comprehensive competitiveness of the product , and provides favorable equipment support for the development of the high - shading decorative product of the subject . ( 2 ) Under the same process and warp and weft density conditions , the light - shielding properties of the double - layer fabric with different tissue cycles are different . As the number of weave cycles is increased , the smaller the number of interweave points per unit area , the less the gap between the yarns , the better the light - shielding performance of the fabric ; and when the number of the same tissue cycles , the light - shielding properties of the fabric are different , and the average light - shielding property : the twill weave twill weave satin weave . and ( 3 ) under the condition that the density of the fabric is certain and the floating length is effectively controlled , the circulation number of the fabric and the average shading rate of the fabric have good exponential relationship , and the fabric shading property tends to be consistent when the number of tissue cycles of the fabric reaches a certain value , and the fabric shading property is not changed even . ( 4 ) Under the same process and surface layer organization condition , with the increase of the number of nodes in the double - layer structure , the light - shielding performance of the fabric is basically consistent and the overall difference is small . ( 5 ) When the warp density is 140 cm / cm , with the increase of the weft density and the proportion of the black weft yarn , the light shielding property of the fabric is remarkably improved , and when the weft density is 96 / cm , the shading rate of the fabric is 99.9 percent , the total shading is realized , but the fabric feels harder . Considering the actual production weaving and application , the upper machine weft density of the high shading decorative fabric can be 72 pieces / cm , and the weft arranging ratio 2 ( black weft ) : 1 : 1 . ( 6 ) In the visible light area , the same process parameters and the fabric shading performance of the surface layer structure : The silk fabric with the same process parameters and the surface layer structure has better shading effect than the DTY silk fabric . ( 7 ) When the warp density is under the condition of 140 cm / cm , the weft yarn raw material and the weft density have little influence on the drape of the fabric , the greater the number of cycles of the fabric in the effective control of the floating length , the better the drape of the fabric . In the development of the product , the material and the weft can be selected according to the actual needs , and the tissue with large number of tissue cycles is preferred . Finally , based on the test results of fabric performance , the weft yarn is selected as weft material with density of 140 root / cm and weft density of 72 root / cm , and the yarn is used as weft yarn raw material according to the ratio of 2 : 1 : 1 and 1 : 1 . The two series ( 6 fabrics ) are used in the design and development of high - shading curtain fabric .
