MANUFACTURING OF PVC/PU SYNTHETIC LEATHER
[CODE NO.4331]
For many years a range of leather like materials has been in use for sockings, linkings and uppers. They are all based of fabrics, usually woven and mainly of cotton. These base cloths should be carefully selected to give the requisite physical properties for shoe uppers and they may be coated with oil or PVC or rubber compound, Cellulose derivatives or synthetic resin (plastics). The surface may be smooth, with high polish or matt effect, or embossed with designs, many of which simulate leather or fabrics. All these coated materials are totally impermeable to air and water, ventilation must therefore achieved by suitable shoe design. The earliest type of leather cloth was American Cloth, the coating being of linseed oil. This was followed by nitrocellulose coating. Both are practically obsolete for uppers, being superseded by plastic coatings, but they are used for sockings.
Plastic sheetings are also used for uppers of cheaper qualities of shoes. For shoe uppers the unsupported sheeting has proved unsatisfactory in making and the more usual upper materials consist of a specially woven fabric coated with a plastic film, nearly always plasticized PVC. Since this synthetic resin the most freely available in all country. The many constructional difficulties are gradually being overcome and owing to the impenetrable nature of a plastic film, the more general finishes cannot be used. PVC upper materials may be cleaned with petroleum cleaners without determinant to the luster of the surface and additional polish may be given by means of wax creams or light polishing on the rotary brush. PVC leather cloth is the most useful plastic. It has two grades, flexible or rigid which give by means of wax creams or light polishing on the rotary brush. PVC leather cloth is the most useful plastic. It has two grades, flexible or rigid which give it considerable scope. The flexible leather sheet is used for articles of clothing such as boot and shoe, sales, heels and uppers etc. In fact the range of products is so wide that it is impossible to state all of them.
PVC leather cloth is also known in other words as Artificial leather which is becoming increasingly popular all over the world because of shortage of actual leather and high cost of the same. Artificial leather is specially suitable for upholstery, shoe upper, attachicases, brief cases and all kinds of bags. It is water repellent and is chemically inert. It is much cleaner both in production and in use beside being competitive in price. Present inductions show that artificial leather goods have good export potential.
How it is possible to manufacture artificial leather in the small scale sector because of the introduction of automatic machines by the world renowned manufacturers of Japan, Akatsuki machinery works Ltd., who have exported already about 2,000 such plants to South East Asia and Middle East countries. The plant designed by them is continuous one line system, ensuring uniform quality of production of artificial leather as well as less labour costs. With the embossing device one can have plain as well as engraved designs manufactured. Colour of coatings would be according to your choice.
Now, the machineries for PVC leather cloth are being manufactured in India by a India renowned manufacturers. A list of such manufacturers is given at the end of this report.
PVC leather cloth is manufactured by applying a coating of PVC paste on cotton cloth. The cloth has a coating with a glossy surfaced and smoothness to tough. It is used in air-proof and water-proof packing and also for decoration. It is extensively used in such applications which require a water proof media and strength. It is comparatively a new technique and has widely growth prospects. In India the manufacture of PVC leather cloth is very limited and there exists lot of scope for new industries in this field.
PVC leather cloths do not get affected by Heat or water. It is a substitute of natural leather cloth.
PVC leather cloth industry cloth industry has now become very common and the manufacturing technique is very simple.
