g真皮皮革雖然廣受大眾喜愛，然其單價高，商品市 %有限。至於人工皮革，雖具有價格上的優勢，但傳統 /‘.、式PU人工皮革利用超細纖維做基布，以強酸強鹼減量 έ /又P U /合液，因而普遍存有不透氣的缺點；雖後期 皮革於製矛王中攙入發泡劑後可以達到透氣目的，然 攙及二化予，奋劑會釋放有毒致癌物質，嚴重影響環 品質與人體健康。 兄 發明人有鑑於傳統人工皮革普遍於製程中攙雜有強Although g leather leather is widely loved by the public, its unit price is high, and the commodity market is limited. As for artificial leather, although it has the advantage of price, the traditional / '., PU artificial leather uses microfiber as the base fabric, and the strong acid and alkali reduce the amount of έ / PU / liquid, so there is a general disadvantage of airtightness. Although the later leather can be ventilated after being injected into the foaming agent, the sputum will release toxic carcinogens, which will seriously affect the quality of the ring and human health. Brother inventor, in view of the fact that traditional artificial leather is generally noisy and strong in the process.
