皮夹克的生产工艺流程英文回答：The production process of a leather jacket involves several steps, starting from the design phase to the final product. Let me walk you through the process.Firstly, the design phase begins with the creation of a concept for the leather jacket. This involves sketching the jacket's style, shape, and detailing. Once the design is finalized, patterns are created for each component of the jacket, such as the front, back, sleeves, and collar.Next, the selected leather material is cut according to the patterns. This is usually done using cutting machines or sometimes by hand. The precision and accuracy of the cuts are crucial to ensure that all the pieces fit together perfectly.After the leather pieces are cut, they are sent to thesewing department. Here, skilled seamstresses stitch the pieces together using specialized sewing machines. Theyjoin the front and back panels, attach the sleeves, and add any additional details like pockets or zippers.Once the main construction is complete, the jacket goes through a process called "grading." This involves checking the measurements and making any necessary adjustments to ensure that the jacket fits properly. For example, if a medium-sized jacket is being produced, the grading process ensures that all medium-sized jackets have consistent measurements.After grading, the jacket moves on to the finishing stage. This involves adding the final touches to the jacket, such as attaching buttons, snaps, or buckles. Any necessary adjustments or repairs are also made at this stage.Finally, the jacket goes through a quality control inspection.

高强高模-聚乙烯纤维工程技术发布时间：2008-01-31 08:58:10 来源：中国纺织品进出口商会[转载]文字选择：大中小盐城市宏迭纺织器材有限公司盐城超强高分子材料工程技术研究所郭子贤上世纪七十年代后期，以粉末状超高分子量聚乙烯为原料，采用全新的冻胶纺丝及超拉伸技术，制得了超高强高模的聚乙烯纤维，使化学纤维和化学纤维工业开始了新的飞跃。

超高分子量聚乙烯纤维具有优异物理机械性能，成为继碳纤维和芳纶之后出现的第三代高性能纤维。

就强度而言，目前绳索可以吊起来的最大重量是同样粗细钢丝绳吊起的最大重量的八倍，是目前已经工业化的纤维中强度最高的纤维，此外，超高分子量聚乙烯纤维的密度小于碳纤维和芳纶，还具有优异的耐化学性和耐气候性，高能量吸收性，低导电性，防水性等特点。

鉴于上述性能，该纤维称为继碳纤维和芳纶之后又一种主要的高性能纤维，目前国际上只有荷兰DsM公司、美国霍尼维尔公司、日本东洋纺公司和中国等几家公司已形成工业化规模的生产。

我国于八十年代后期由东华大学率先提出对超高分子量聚乙烯纤维项目的研究与工业化，到九十年代后期相继出现r宁波大成、北京同益中、湖南中泰在东华大学研究的lT艺成果基础上进行r小试、巾试工业化生产开发。

时至今日，上述三家企业都已形成了规模产业化生产，但由于受到工艺和装备技术不成熟条件的限制，三家企业尽管都耗费了大量的人力、物力，也走上了效益化的生产道路，但由于二三家企业的工艺力式，设备配置各不相同，故而，三家企、Ik的单机产量，产品质量，差异较大。

根据国内外用户的反映，目前，国内厂家纤维品质最好的厂家是北京同益中特中纤维技术开发有限公司、山东爱地高分子材料有限公司。

盐城市宏达纺织器材有限公司从八十年代初开始从事化纤设备的研发与制造，特别对纤维加热设备的研发具有较强的基础与实力，本公司1998年与北京同益中公司达成共同开发年产100吨高强高模聚乙烯纤维工程、装备技术的协议。

此要求在当时可谓技术难度大，起点比较高，就国内而言属革命性技术突破。
