Abstract

Large amounts of leather-cutting wastages have been generated for the production of leather-goods in the industry. Nowadays, the solid waste management is difficult challenge and important concern for sustainable and cleaner processing to minimize the wastage by recycling/re-use. Our present study is about the development to make the different types of ladies-jewelry such as Bracelet/Anklet, Necklace, Earrings, Ring, and Bangles from the leather cutting wastages. The patterns making and cost calculation was evaluated by the systemic way. Finally, the jewelry was survey through to the 50 female student (age range: 18~30 years) by a questionnaire. The questionnaire involves five different sector, they are wearing comfort, fashion fact, quality, costing & interest in buying and recommendations. The items are rated on a scale of 1 to 5, where 1 being strongly disagree, 2 being disagree, 3 being average/ undecided, 4 being agree and 5 being strongly agree. The statistical analysis such as level of satisfaction, median, coefficient of variance (CV), variance, Standard Deviation (STDEV) and mean value were calculated by a systemic way. The survey results shows the Level of satisfaction value greater than 70% of each cases and it`s a satisfactory level.

  1. INTRODUCTION

    Leather has played an important role in day-to-day life of humankind from immemorial. Human from the very beginning, has been using animal skins for covering their body & legs from climate conditions, keeping the provisions of water in goatskins and making the belts for various purposes. From ancient civilization to modern times, the human race one from has used leather or the other in its daily life and it is discovered everywhere. It`s seems the humankind can hardly do without these useful materials.

    The global need for leather products is steadily flourishing an aptitude like to walk because of population swelling and economic improvement [1]. Sustain raise competitiveness of an economy is an impress of economic power and permanence of that economy [2]. The term Leather Goods is applied & confined generally to the articles or goods made, mainly of

    leather & intended for carrying personal belongings, such as the smaller items, which can be carried in hand or shoulder. The variety of leather goods we come across everyday is countless. When there are a variety of articles that differs so much in size, design & method of construction, then it is necessary to classify them into separate convenient articles of similar kind. In this report, classification of leather good has been defined in confined terms [3].

    The undesired portion of the any material, especially for leather, lining materials, reinforcement materials etc, that are left after cutting the material is called wastage/waste materials.

    The cuttability grades of leather; on first grade leather, normally an allowance of 3% is given while on the other grade it is varied by 5% [4]. Since only about 50-55% of corium collagen actually ends up as finished leather it is not surprising that a tannery generates large amounts of solid wastes. As a matter of fact, utilization and/or disposal of solid waste is one of the most difficult challenges especially in countries with confined legislation and enforcement pertaining to waste handling. Moreover, it is very likely that the pressures will escalate further. 1000kg of wet salted cattle hides, weight class about 25.6 kg per hide processed to shoe uppers, about 5~10 kg finished leather trimmings have been produced [5].

    Design & development (pattern development is the offshoot of design & development) is of utmost importance for processing and marketing of leather goods. Without proper conception or grasp of functional value, no design could convert into a fabricated product and such work relating to the design and pattern development aspect of leather goods manufacturing cannot be over-emphasized.

    For performing the above task, a leather-cutting wastages- product must have a unique-design and a broad outline of what have originated before the advent of design in dealt with, it started first with the purpose of utility. This paper, tries to make a market-demand products and survey the product through to the 50 female students. In addition, it can enhance the quality & effectiveness of cost of leather-jewelry that could be mostly demanded for the women and maximum

    utilization of value-added product to decreases the solid waste of a leather-goods industry.

  2. MATERIALS AND METHOD

    1. Selecting leather-wastages for the manufacturing of jewellary

  4. CONCLUSIONS

The products made out of leather and themselves to an enormous variety of both useful & essential items, which are a need and asset in modern living. An extensive range of colors & designs widen the selection range which encourage the prospective consumers to put this product to use in a multitude of ways be it fashionable or functional.

Designing is an important process in the manufacture of ladies jewelries. In the principle of designing, a good design should be easy for fabrication & saleable. The design should

be simple when it is covered into production as much as possible, because production & productivity are the key factors for successful commercial venture. Assembling of too many components for multipurpose functions must be avoided as much as possible. It affects the important aspects of designing namely, size, shape, structure attraction & value appearance. In good designing, techniques & technical skills are very important. A good design should not impart the functions of the products for which they are manufactured.

It is indeed true that we are accustomed and habituated to use small leather goods not only in our life but also in our professional life largely. For instance, we use wallet, passport cases and coin boxes to maintain the daily money handling personally. Notwithstanding, using of leather goods is also a matter of status and prestige and gratifying. It is an irony of fate that making process of small leather goods difficult not only to maintain the quality but also to produce a better shape. It is imperative that, new entrepreneurship will make a base for exporting the small leather goods after consuming local demands, should consider the customers capability to buy the products. Foreign currency can be gained in a significant way which may develop the country economy as raw material and labor are two most important factor but

available in our country.

It can be conclude that, easily increase the level of satisfaction by taking idea and suggestions from the user. It will help us to increase the acceptance of the jewelry and reduce the wastage.
