具有低表面能纤维的制造方法、具有低表面能纤维、纱线、以及织物Manufacturing method of fiber with low surface energy, fiber with low surface energy, yarn, and fabric

技术领域technical field

本发明是关于一种纤维的制造方法，尤其是关于一种具有低表面能纤维的制造方法。 The invention relates to a method for manufacturing fibers, in particular to a method for manufacturing fibers with low surface energy. the

背景技术Background technique

以往具有低表面能(低表面张力)功能的织物，其制造方式通常是对布料施以低表面能助剂的加工制程，例如使用涂布、浸置、压吸等方式使低表面能助剂附着于布料上，再以约100～210℃的加热温度使助剂固着于布料上而得到。 In the past, fabrics with low surface energy (low surface tension) functions were usually manufactured by applying low surface energy additives to the fabric, such as coating, immersion, pressure suction, etc. to make the low surface energy additives It is obtained by adhering to the fabric, and then fixing the auxiliary agent on the fabric at a heating temperature of about 100-210°C. the

台湾专利申请案第098110619号(以下称为专利文献1)公开一种具有拨水性的纱线的制造方法，是将待处理纱线依序通过一盛有拨水剂的药槽以沾附拨水剂，进而通过一热处理单元以使该拨水剂固着于该待处理纱线，形成具有拨水性的纱线。但是该方法需要依序经过药槽单元与热处理单元，造成加工时间长、增加成本外，且拨水剂在热处理单元上因受热而结焦垢，进而，由于拨水剂仅附着在纱线表面，在后续处理中(例如合纱处理)可能会沾附到其他不希望有拨水性的纱线上。 Taiwan Patent Application No. 098110619 (hereinafter referred to as Patent Document 1) discloses a method for manufacturing water-repellent yarns. The yarns to be treated are sequentially passed through a tank filled with water-repellent agents to adhere The water agent is further passed through a heat treatment unit to fix the water repellent agent on the yarn to be treated to form a water repellent yarn. However, this method needs to pass through the medicine tank unit and the heat treatment unit in sequence, resulting in long processing time and increased costs, and the water-repellent agent is coked and scaled on the heat-treatment unit due to heat. Furthermore, since the water-repellent agent only adheres to the surface of the yarn, In subsequent processing (such as yarn closing processing), it may adhere to other yarns that do not want water repellency. the

另外，中国专利申请公开号CN101984154(以下称为专利文献2)揭露一种拒水聚酯纤维的制造方法，是将拨水剂等直接添加在纺丝油剂中，而于熔融纺丝过程中使得拨水剂直接附着在纤维表面上，以制得具有拒水性的纤维。但是此方法在后段加工过程由于附着在纤维表面上的拨水剂受热后容易粘着在热板上而产生不易清洗、刮除的焦垢，不仅导致热板设备受损，且纤维会因而受热不均，影响织物品质。 In addition, Chinese Patent Application Publication No. CN101984154 (hereinafter referred to as Patent Document 2) discloses a method for manufacturing water-repellent polyester fibers, which is to directly add a water-repellent agent to the spinning oil, and in the melt-spinning process The water-repellent agent is directly attached to the surface of the fiber to obtain a water-repellent fiber. However, in the latter part of the process, the water-repellent agent attached to the surface of the fiber is easy to stick to the hot plate after being heated, resulting in scorched dirt that is difficult to clean and scrape off, which not only causes damage to the hot plate equipment, but also heats the fiber. Unevenness affects fabric quality. the

进而，上述背景技术，所制得的具拨水性纤维/纱线，经过多次水洗后， 附着于纤维/纱线表面的拨水剂易被洗出，具体而言，以AATCC(American Association of Textile Chemists and Colorists)-135标准水洗20次左右，纤维拨水效果即会明显变差。 Furthermore, in the above-mentioned background technology, the prepared water-repellent fiber/yarn is washed with water for many times, and the water-repellent agent attached to the surface of the fiber/yarn is easily washed out. Specifically, according to AATCC (American Association of Textile Chemists and Colorists)-135 standard water washing about 20 times, the water repellent effect of fibers will be obviously deteriorated. the

2.织物表面张力测试 2. Fabric surface tension test

分别使用具有不同表面张力的墨(市售的达因笔)，于实施例及比较例所得织物上划约10cm墨痕，观察墨痕的90%以上是否在2秒钟内发生收缩并形成墨滴，如有，则换表面张力较低的墨水再进行划痕并观察，直至墨痕不再收缩和出现墨滴，即为该织物所对应具有的表面张力。 Use inks with different surface tensions (commercially available dyne pens) to draw ink marks of about 10 cm on the fabrics obtained in Examples and Comparative Examples, and observe whether more than 90% of the ink marks shrink and form ink within 2 seconds. Drops, if there are, change the ink with lower surface tension and scratch and observe until the ink marks no longer shrink and ink drops appear, which is the corresponding surface tension of the fabric. the

3.拨水测试： 3. Water repellency test:

将实施例及比较例所得织物裁剪成为180mm×180mm的大小，将拨水测试面朝上以成45度倾斜的方式固定在设于基座上的套环处，将250cc的水以30秒流过织物表面，从基座上取下套环轻拍，依据FTTSS-FA-011进行评价。 Cut the fabrics obtained in Examples and Comparative Examples into a size of 180mm×180mm, fix the water-repellent test surface on the collar on the base at an angle of 45 degrees, and let 250cc of water flow for 30 seconds. Pass the surface of the fabric, remove the collar from the base and pat it gently, and evaluate according to FTTSS-FA-011. the

100分：表面没有湿润 100 points: the surface is not wet

90分：表面稍有湿润 90 points: the surface is slightly wet

80分：表面呈分散水滴状的湿润 80 points: The surface is wet in the form of dispersed water droplets

70分：表面大部份有湿润 70 points: most of the surface is wet

50分：表面全部均有湿润 50 points: the entire surface is wet

0分：完全湿润 0 points: completely wet

4.加工热板焦垢累积 4. Accumulation of scorched scale on the processing hot plate

观察各实施例与比较例当中所使用的加热单元(热板或热轮)于运转1天后焦垢累积状况，评价方式如下： Observe the scorching accumulation status of the heating unit (hot plate or hot wheel) used in each embodiment and comparative example after running for 1 day, and the evaluation method is as follows:

出现大量焦垢：╳ There is a lot of scorching scale: ╳

有少量焦垢或无焦垢：○ A small amount of scorching or no scorching: ○
