1.PVC人造革气味来源主要是生产原料在合成过程中带入的助剂/溶剂，及高温下高分子材料的降解产生。

2.气味评测受评测体系内某物质含量/浓度贡献最高影响。

3.通过对PVC革体系中添加绿色环保级香精，提升气味评测体系内香精成分浓度，提高气味贡献度，达到气味改善提升，避免传统“喷香”“刷香”短暂的气味愉悦感。

4.PVC香味革主要闻到的是留香持久的中香和尾香。

The main source of odor in PVC synthetic leather is the additives/solvents introduced by the production materials during the synthesis process, as well as the degradation of polymer materials at high temperatures.

2. Odor evaluation is most affected by the contribution of a certain substance content/concentration within the evaluation system.

3. By adding green environmental protection essence to the PVC leather system, the concentration of essence components in the odor evaluation system will be increased, and the odor contribution will be increased, so as to improve the odor and avoid the short-term pleasant smell of traditional "fragrance spraying" and "fragrance brushing".

4. PVC scented leather mainly smells a long-lasting mid fragrance and tail fragrance.

PVC香味革制备方法包含步骤为：

（1） 制备PVC糊料，所述PVC糊料包含由PVC组成的第一组分、由增塑剂、稳定剂组成的第二组分和由填料、加工助剂、功能助剂组成的第三组分，这些组分通过搅拌方式相互混合成为所述PVC糊料。
（2） 在PVC糊料制过程中添加香精，通过搅拌方式混合均匀后后使用。
（3） 通过离型纸承载方式，涂覆上述PVC糊料；通过加热方式将其胶化成膜，并与织物粘结成 PVC革。

The preparation method of PVC fragrant leather includes the following steps:

(1) Prepare PVC paste, which includes a first component composed of PVC, a second component composed of plasticizers and stabilizers, and a third component composed of fillers, processing aids, and functional aids. These components are mixed with each other by stirring to form the PVC paste.

(2) Add essence during the preparation of PVC paste, mix it evenly by stirring, and then use it.

(3) Coating the above-mentioned PVC paste through release paper bearing method; By heating, it is gelatinized into a film and bonded to the fabric to form PVC leather.
