नवीकरणीय चमड़े के चमड़े और कृत्रिम चमड़े की परिभाषा

पुनर्जीवित चमड़े की तकनीक:

चमड़े के फाइबर के लिए है, मिश्रित क्रॉसलिंकिंग फाइबर, राल और अन्य योजक. इसकी तकनीकी प्रक्रिया है: चमड़े या पुनर्जीवित चमड़े की सामग्री को त्वचा फाइबर के पैमाने पर होना चाहिए, और फिर प्राकृतिक रबर के साथ, राल और अन्य सामग्री, मिलाने के बाद, compresses it into filter cake; Heat the filter cake, make its surface fiber melt viscosity, each layer of kneading, glue, dehydration, असबाबवाला कुर्सी, slice, embossing and appearance treatment after get all goods. Primary features: regeneration characteristics of both leather and पीयू चमड़ा, leather fabric is now very common. The same with genuine leather, bonded leather has hygroscopic, permeability, good work also has the same leather softness, लोच, हल्की बनावट, high and low temperature tolerance of strong, wear-resisting of pole. Its lack of equality is the difference in the intensity of the thickness of the dermis, and worse than PU, बिल्कुल, is not suitable for making shoe force large leather goods, आदि. Due to the production technology of regenerated leather contrast sensitivity, and can be adjusted in real time, and by adding the dosage of the natural latex, changes in technology formula, the same can make all kinds of different hardness, different intensity of goods to compensate for the lack of her own. Its appearance in the late processing similar to PU, recycled leather in appearance, texture and color is not only the innovation, the new product emerge in endlessly through designs. More importantly she competitive offer, is only one over ten of the genuine leather, PU microfiber, three times as very good value, high cost performance.

The varieties of leather and to identify the difference

Leather is divided into natural leather (चमड़ा), पुनर्नवीनीकरण चमड़ा, कृत्रिम चमड़े (PU/PVC). Leather are cattle, भेड़, सूअर, घोड़े, हिरन, or some other animals off the original skin, after tannery processing, विभिन्न विशेषताओं से निर्मित, ताकत, हैंडल, color, pattern leather material, आधुनिक चमड़े के उत्पादों की आवश्यक जानकारी है. Leather is usually by the epidermal layer (remove), the dermis, the reticular layer, चमड़ा (out) at the grass-roots level, आदि. इस दौरान, मवेशी का चमड़ा, sheepskin, तथा pigskin leather is used three leather material.

ए, चमड़ा, leather and head skin and skin difference on the second floor.

(1) : the head skin refers to with a grain of cattle, भेड़, pig skin (डर्मिस), such as leather have natural special texture effect. Imported leather and possibly trace. All full grain can from the thickness and pore density difference is in what kind of animal leather. There are kinds of leather, जैसे कि: गाय का चमड़ा (grazing cattle leather, चमड़ा, चमड़े की पहली परत, bull leather, बधिया बैल का चमड़ा नहीं और बधिया किया हुआ सांड का चमड़ा), भैंस की खाल, गाय का चमड़ा, yak skin and skin of zho, cattle leather best belong to shandong, henan provinces in China and central China, but China’s leather capital shortage (such as the United States, Brazil beef exporter incidence rate is the most profitable). Cow leather is a buffalo hide pore fine and dense, grain fine flat. Buffalo hide pore is thick and thin, is single, grain AoTuGan, buffalo hide in sichuan, jiangxi and other parts of the is better, but capital is relatively short (such as India and Egypt area more); Sheep skin first sheep skin, goatskin, gambolling. Skin pores are more fine more dense, special texture like copper. Goats for shoemaking, sheep for more clothes. Sheepskin in sichuan, hubei and other places the best (the capital of Australia’s most profitable, and wide thick skin). Pigskin for hairy rules are 3 root a handful of “product” glyph spread, इसलिए अंतर करना आसान है, usually use artificial breeding pig skin, and skin. Other like ostrich, crocodile, short nose crocodile fish, छिपकलियां, snakes, bullfrog, ocean fish, there’s a shark, कॉड, SLATE cod croaker fish, eels, pearl, आदि।), freshwater fish (जैसे ग्रास कार्प, carp fish have scales) and so on also is to make the original data. Also have used as senior clothing hairy skin, professional call fur or fur, जैसे कि: लोमड़ी, चांदी लोमड़ी की त्वचा, नीली लोमड़ी, आदि।), भेड़िया त्वचा, dogskin valuable water mink, rabbit skin and various rare and precious animal skins, आदि.

(2) : second floor skin without the dermis, is a fibrous tissue (network layer), chemical materials cover the spraying or in PVC, PU film processing and become, as a result, the difference between head skin and useful way of skin on the second floor, फाइबर घनत्व के चमड़े के अनुदैर्ध्य खंड की जांच की गई. By head skin is thick and thin dermis and closely together constitute a little loose reticular layer, उत्कृष्ट ताकत के साथ, लोच और प्लास्टिसिटी और अन्य विशेषताएं. 2 रेशेदार ऊतक की ढीली त्वचा की परत जितने लंबे होते हैं (network layer), as long as the ability after spraying chemical material or mill used to make leather products, यह अपनी प्राकृतिक लोच बनाए रखता है और प्लास्टिसिटी तकनीक की विशेषता अवश्य होनी चाहिए, but strength is a bit poor, with the first layer of skin deep like its practices requirements. Is not the same it has a fluffy effect, can produce a series of different from the role of the first layer. Yak wool and pig hair usually use more, and scrubbing technology for special deer velvet. And for now prevail in manufacturing all kinds of leather, चमड़ा प्रसंस्करण तकनीक कुछ अलग, लेकिन अंतर विधि वही है.

दूसरा, the bonded leather: also called chaff leather paper abroad.

Will cost of various animals, leather and leather scraps from the damaged deployment of chemical material processing. उपस्थिति प्रसंस्करण प्रौद्योगिकी चमड़े के चेहरे के समान है, उभरा हुआ चमड़ा समान है, its characteristic is the skin marginal is neat, high utilization ratio and offer cheap; लेकिन त्वचा आमतौर पर मोटी होती है, ताकत गरीब है, अटैची, रॉड बैग, माल और सस्ती बेल्ट के समता क्लब सेट के निर्माण के लिए ही उपयुक्त है, finalize the design technologies such as the longitudinal section fibrous tissue even common, are recognized liquid mixing and coagulation effect of fiber.

तीन, कृत्रिम चमड़े, इसे इमिटेशन लेदर या रबर भी कहा जाता है, पीवीसी और पीयू कृत्रिम डेटा का फ्लोरबोर्ड है. And microfiber leather, which is the best चमड़े का विकल्प.

यह कपड़ा वाहिनी या गैर बुने हुए आधार पर है, पीवीसी और पीयू फोम या लैमिनेटिंग प्रोसेसिंग मैन्युफैक्चरिंग के सभी प्रकार के फॉर्मूलेशन और बन जाते हैं, अलग-अलग ताकत के अनुसार कर सकते हैं, पहनें का विरोध, ठंड प्रतिरोधी डिग्री और एक रंग और चमक, speckle figure case demand such as processing, pattern variety, good waterproof performance, दिखावट साफ-सुथरा रखें, उच्च उपयोग अनुपात और अपेक्षाकृत सस्ते असली चमड़े की विशेषताएं प्रदान करते हैं, but the vast majority of artificial leather, इसका हैंडल और इलास्टिक वास्तविक चमड़े का प्रभाव देने में असमर्थ है; इसका अनुदैर्ध्य खंड, आप बारीक बुलबुला छेद देख सकते हैं, cloth base or the surface of thin film and dry dry artificial fibers. यह हमेशा से ही अब तक की शुरुआत है, एक प्रकार का डेटा बहुत लोकप्रिय है, इसका उपयोग सभी प्रकार के चमड़े के उत्पादों के उत्पादन के लिए किया जाएगा, or part of the leather materials. यह तेजी से अग्रणी विनिर्माण प्रौद्योगिकी है, दूसरी मंजिल के चमड़े के प्रसंस्करण और विनिर्माण में व्यापक रूप से उपयोग किया जाता है. Now, like a feature of genuine leather artificial leather in a growing, इसका प्रौद्योगिकी चरम रेशेदार ऊतक दिखता है, चमड़े की भूमिका तक पहुँच सकते हैं, कीमत उचित है. But real leather and artificial leather (renewable leather and artificial leather) cannot than: common health (natural pores and fiber) and durability.

From the level of the leather points: all full grain > half full grain > light repair face > rebuild face

Points: from leather softness of chrome tanned leather > half tanned skin > whole plant tanned skin graft (त्वचा)

From leather personality practice points: चमड़ा स्थानापन्न सामग्री, water dyed leather, grain leather, wax napa leather, चमड़ा, उभरा हुआ चमडा, light skin, उपयोग, the paster skin face, रँगना, printing of skin, त्वचा, the skin of crack, आदि. Very much, because you touch is benzene, phenol, alkyl, alkene chemicals, is very harmful to human body, if factory does not have outstanding protective measures, with a high likelihood of aplastic anemia, and cancer.

Chaff bonded leather (leather paper) is to use leather waste and leather processing occurs in the process of edge horn broken material, back after processed into high value-added goods, चमड़े की वस्तुएं, जूते, furniture and other related leather manufactures throughout the use of auxiliary materials. Chaff as a center of interlining, bonded leather (leather paper), with its unique texture, FLEXIBILITY, बेरहमी, resistance to wet ability and replaces cardboard processing adaptability. As fabric, bonded leather by embossing and printing, and PU composite can appear all sorts of function, चमड़े के सामान में व्यापक रूप से उपयोग किया जाता है, फर्नीचर, books, etc for the cover. According to incomplete statistics, China’s current need to be imported from abroad each year more than 8400 tons of raw hides, the intention to be success, to fill the gaps in China to produce raw hides.
