一种透气保暖的羽绒服面料及其制备方法A kind of breathable and warm down jacket fabric and preparation method thereof

技术领域technical field

本发明属于服装加工技术领域，具体涉及一种透气保暖的羽绒服面料及其制备方法。The invention belongs to the technical field of garment processing, and in particular relates to a breathable and warm down jacket fabric and a preparation method thereof.

背景技术Background technique

服装以面料制作而成，面料就是用来制作服装的材料，羽绒服也不例外。作为服装三要素之一，面料不仅可以诠释服装的风格和特性，而且直接左右着服装的色彩、造型的表现效果，呈现出自身的高贵完美，手感柔软。但是从总体上来讲，羽绒服优质、高档的面料，大都具有穿著舒适、吸汗透气、悬垂挺括、视觉高贵、触觉柔软等几个方面的特点。特别是，由于清洗频率相对较低，在保暖性等性能方面就有着更为严格的要求。现有的羽绒服面料大都采用表面涂敷法涂覆多层功能性涂层，虽有一定的防风、保暖性能，但是因表面涂敷开孔极不均匀和涂层性能的不稳定，导致透气性较差，不能适应户外严寒环境下穿着使用。Clothing is made of fabric, and fabric is the material used to make clothing, and down jackets are no exception. As one of the three elements of clothing, fabric can not only interpret the style and characteristics of clothing, but also directly influence the performance of color and shape of clothing, showing its own noble perfection and soft feel. But in general, the high-quality and high-grade fabrics of down jackets are mostly characterized by comfortable wearing, sweat absorption and breathability, drape and rigidity, visual elegance, and soft touch. In particular, due to the relatively low frequency of cleaning, there are more stringent requirements in terms of performance such as warmth retention. Most of the existing down jacket fabrics are coated with multi-layer functional coatings by the surface coating method. Although they have certain windproof and thermal properties, due to the extremely uneven opening of the surface coating and the unstable coating performance, the air permeability is caused. Poor, can not adapt to wear and use in outdoor cold environment.

从上表数据可以看出，本发明实施例1-3制得的羽绒服面料具有极好的保暖、透气性能，通过采用70％涤纶、30％聚芳酯纤维编织而成的基布层，这样制成的面料弹性好，拉伸断裂强度高，透气性好；具体的，保暖层由聚氨酯、二氧化硅气凝胶、多孔石墨烯颗粒、改性致孔剂制备而成，由实施例1-3的实验结果可以看出，聚氨酯具有良好的粘接强度、韧性与耐磨性，染整结合在在基布层面料后，表面能低的有机硅链段可向织物表面富集，而聚氨酯链段靠近织物，通过氢键、化学键与织物紧密粘接，兼顾实现拒水和与织物粘接性均较好的目的，同时还能大幅提升面料的保暖性能，又通过二氧化硅气凝胶、多孔石墨烯颗粒的联用，二氧化硅气凝胶内存在无数多个纳米级的气孔，能够提高保温和透气性能，石墨烯具有远红外效应，能够辅助提高二氧化硅气凝胶的保温效果，另外本申请采用的是多孔石墨烯颗粒，给面料提供高保暖性能的同时具备透气能力；又从实施例1和对比例1的实验结果可以看出，不添加二氧化硅气凝胶羽绒服面料保暖性能和透气性能大幅降低，这是由于氧化硅气凝胶内存在无数多个纳米级的气孔，能够提高极高的保温性能和透气性能；又从实施例2和对比例2的实验数据可以看出，将保暖层制备原料中的改性致孔剂替换为常规致孔剂保暖性能和实施例1-3中制得的面料的保暖性能差异不大，但是透气性能却大幅降低，这是由于改性致孔剂可以使聚氨酯内成孔的物质，在聚氨酯形成微孔的过程中，加入改性致孔剂可以改善聚氨酯的微孔结构，从而改善聚氨酯的透气性能，而常规致孔剂虽然也有使聚氨酯内成孔的功能，但：改性剂恶唑啉的加入会以多分子堆积的形式对致孔剂形成有效包覆，恶唑啉本身亲水，透湿、透气性得到增强；透气性的增加会使聚氨酯的力学性能降低，从而提升保暖层的触摸手感；最后从实施例3和对比例3的实验数据可以得到，不添加改性致孔剂的保暖层保温性能和透气性能达到最低，因此可以论证上述结论。It can be seen from the data in the above table that the down jacket fabrics prepared in Examples 1-3 of the present invention have excellent thermal insulation and air permeability. The prepared fabric has good elasticity, high tensile breaking strength, and good air permeability; specifically, the thermal insulation layer is prepared from polyurethane, silica aerogel, porous graphene particles, and modified porogen. Example 1 From the experimental results of -3, it can be seen that polyurethane has good bonding strength, toughness and wear resistance. After dyeing and finishing is combined with the base fabric, the organic silicon segments with low surface energy can be enriched on the surface of the fabric, while the The polyurethane segment is close to the fabric, and is closely bonded to the fabric through hydrogen bonds and chemical bonds. It can achieve both water repellency and good adhesion to the fabric. At the same time, it can greatly improve the thermal performance of the fabric. The combination of glue and porous graphene particles, there are countless nano-scale pores in the silica aerogel, which can improve the thermal insulation and air permeability. The thermal insulation effect, in addition, the application uses porous graphene particles, which provides high thermal insulation performance to the fabric and has air permeability; from the experimental results of Example 1 and Comparative Example 1, it can be seen that silica aerogel is not added. The thermal insulation performance and air permeability of down jacket fabrics are greatly reduced, which is due to the existence of numerous nano-scale pores in the silica aerogel, which can improve extremely high thermal insulation performance and air permeability; It can be seen from the data that the thermal insulation performance of the modified porogen in the preparation raw material of the thermal insulation layer is replaced by a conventional porogen and the thermal insulation performance of the fabrics prepared in Examples 1-3 has little difference, but the air permeability is greatly reduced. This is because the modified pore-forming agent can make the material that forms pores in the polyurethane. In the process of forming micropores in the polyurethane, adding the modified porogen can improve the microporous structure of the polyurethane, thereby improving the breathability of the polyurethane. Although the pore agent also has the function of forming pores in the polyurethane, the addition of the modifier oxazoline will effectively coat the porogen in the form of multi-molecular stacking. The oxazoline itself is hydrophilic, moisture-permeable and air-permeable. The increase in air permeability will reduce the mechanical properties of polyurethane, thereby improving the touch feel of the thermal insulation layer; finally, it can be obtained from the experimental data of Example 3 and Comparative Example 3 that the thermal insulation performance of the thermal insulation layer without modified porogen is added. and air permeability to the lowest, so the above conclusion can be justified.

以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the patent of the present invention.
