Teri - bu insoniyat tarixidagi eng qadimgi materiallardan biridir. O'nlab tarixga ko'ra, odamlar bezatish va himoya qilish uchun hayvonlar mo'ynasidan foydalanishni boshladilar. However, the initial leather manufacturing technology was very simple, just soaking the animal fur in water and then processing it. With the changes of the times, human leather manufacturing technology has gradually evolved and improved. Dastlabki preparat ishlab chiqarish usulidan zamonaviy industrial ishlab chiqarishning zamonaviy ishlab chiqarishi, teri materiallari inson hayotida tobora muhim ahamiyat kasb etmoqda.
Erta teri ishlab chiqarish
The earliest leather manufacturing can be traced back to the ancient Egyptian period around 4000 BC. At that time, people soaked animal fur in water and then processed it with natural vegetable oil and salt water. This manufacturing method is very primitive and cannot produce high-quality leather materials. In addition, a lot of labor and time are required in the production process. Biroq, charm materiallarining kuchli va chidamliligi tufayli ular qadimgi jamiyatda kiyim-kechak, poyabzal, sumkalarni va boshqa buyumlarni tayyorlash uchun keng qo'llanilgan.
With the changes of the times, human leather manufacturing technology has also gradually developed. Around 1500 BC, the ancient Greeks began to use tanning technology to process animal fur to produce softer and more durable leather materials. Tanlash texnologiyasining printsipi - bu hayvonlarning uyasidagi kollagendan boshqa mo'ynali rangli, suvga chidamli, korroziyalarga chidamli va boshqa xususiyatlarga ega bo'lgan. This manufacturing method was widely used in the ancient Middle East and Europe and became the main method of ancient leather manufacturing.
Haqiqiy teri hayvon mo'ynasidan yasalgan tabiiy charm materiallarni anglatadi. Teri terisi ishlab chiqarish texnologiyasi teri ishlab chiqarishdan ko'ra ko'proq rivojlangan va murakkabdir. Teri ishlab chiqarishning asosiy jarayonlariga quyidagilar kiradi: hayvonlarning mo'ynasi, namlash, yuvish, ovlash, bo'yash va qayta ishlash. Ular orasida taniqli va bo'yash haqiqiy charm ishlab chiqarishning eng muhim qadamlari.
Tanlash jarayonida, odatda ishlatiladigan varaqli materiallar, sabzavot materiallari, Chrome Taning materiallari va sintetik ashyo materiallari kiradi. Ular orasida Chronik varaqali materiallar ularning afzalliklari tufayli, ular tezkor qayta ishlash tezligi, barqaror sifati va yaxshi ta'siri kabi keng qo'llaniladi. However, the wastewater and waste residues generated during chrome tanning will pollute the environment, so they need to be reasonably treated and managed.
During the dyeing process, genuine leather can be dyed in different colors as needed to achieve different decorative and protective effects. Before dyeing, the genuine leather needs to be surface treated so that the dye can fully penetrate and fix on the leather surface. Hozirgi vaqtda bo'yoqlarning turlari va sifati doimiy ravishda yaxshilanmoqda, bu esa odamlarning boshqa ehtiyojlari va charm materiallari uchun imtiyozlar bilan tanishishi mumkin.
PU va PVC Teri ishlab chiqarish
Kimyoviy texnologiyaning doimiy rivojlanishi bilan odamlar asta-sekin charmning ko'rinishi va tuyg'usini taqlid qiladigan va yaxshiroq plastikchilik, gidroizlik va chidamlilikka ega bo'lgan ba'zi yangi sintetik materiallarni kashf etdilar. These synthetic materials mainly include PU (polyurethane) leather and PVC (polyvinyl chloride) leather.
Pu Teri - bu yumshoqlik, suvga chidamliligi, qarshiligi va ko'z yoshlari bilan chidamlilik xususiyatlariga ega bo'lgan puliulyatsiyalangan teri. Uning ishlab chiqarish usuli, poliuretan materialni tolali yoki to'q bo'lmagan materialdagi poliuretan materiallarini paltodir va kalenderli materialni kalender materialini tuzadi va charm materialni tuzish, bronlash, bo'yash va boshqa jarayonlarni shakllantirish. Pu Teri haqiqiy teri bilan taqqoslaganda kam xarajat va oson ishlov berishning afzalliklariga ega va turli xil rang va to'qima effektlarini taqlid qilishi mumkin. It is widely used in the production of clothing, shoes, furniture and other products.
PVC Teri - bu polivinil xlorid materikidan tayyorlangan teri, suv o'tkazmaydigan, kiyingan va tozalash oson bo'lgan polivinil xlorid materialidan tayyorlangan teri. Uning ishlab chiqarish usuli - polivinil xlorid materialini substratda palto qilish, so'ngra taqvodlash, bo'yash, bo'yash va boshqa jarayonlar orqali charm materialni hosil qiladi. Compared with PU leather, PVC leather has the advantages of lower cost and stronger toughness, and can simulate various colors and patterns. Bu avtomobil o'rindiqlari, yuklar, sumkalar va boshqa mahsulotlar ishlab chiqarishda keng qo'llaniladi.
So'nggi yillarda an'anaviy chinakam charm va charmdan tashqari, charm materiallar, kremniy teri, kremniy teri paydo bo'ldi. Silikon charm - bu engil kremikon materiallari va sun'iy tolali qoplamadan yasalgan sun'iy charm.
Silikon teri keng qo'llaniladi va avtomobil ichki kiyimlari, sumkalari, uyali telefon va boshqa mahsulotlar tayyorlash uchun ishlatilishi mumkin. PU va PVC Teri bilan solishtirganda, silikon charm, uv qarshilikka chidamliligi, tuz purkasi chidamliligi va yuqori haroratli qarshiligi va yoshga to'lgan va yoshga to'lgan va o'sish oson emas. Bundan tashqari, kremniy teri ishlab chiqarish jarayonida zararli gaz va oqava suvlar ishlab chiqarilmaydi va atrof-muhitga ifloslanish kamroq.
Xulosa
Qadimgi va moda materiallari sifatida charm uzoq rivojlanish jarayonidan o'tgan. Hayvonlarning dastlabki teridan ishlov berish, PU, PVC, PVC charm va siokon teri, teri sifati va sifati doimiy ravishda takomillashtirildi va ariza miqdori doimiy ravishda kengayib bordi. Bu chinakam charm yoki sintetik charmmi, o'ziga xos afzallik va kamchiliklarga egami, ulardan foydalanganda odamlar turli xil ehtiyojlar va stsenariylarga muvofiq tanlashlari kerak.
Zamonaviy ishlab chiqarish texnologiyasi va kimyoviy materiallar ko'plab an'anaviy terilarni tayyorlash usullarini almashtirgan bo'lsa-da, haqiqiy charm hali ham qimmatbaho materiallar va uning noyob hissi va tuzilishi uni yuqori darajadagi mahsulotlar uchun birinchi tanlov qiladi. Shu bilan birga, odamlar atrof-muhitni muhofaza qilish muhimligini asta-sekin tushunib, an'anaviy sintetik charm o'rniga ekologik toza va barqaror materiallardan foydalanishga harakat qilishdi. Silicone leather is one of the new materials. It not only has excellent performance, but also has less pollution to the environment. It can be said to be a very promising material.
Qisqasi, fan va texnika va odamlarning ekologik himoya, charm, qadimiy va moda materiallariga doimiy ravishda rivojlanib boraveradi va rivojlanib bormoqda.
