Expansion of the range of garments, in particular women’s winter coats made of woolen fabrics, and a significant improvement in their quality will occur through the use of new modern materials, improvement of the external design of clothing in accordance with fashion trends, improvement of product designs, manufacturing technology and the introduction of an integrated quality management system products.
At present, enterprises producing mass-produced clothing are characterized by a high level of technology, technology and production organization, which places special demands on those working at these enterprises.
Making clothes is a complex process. To create high-quality products, highly qualified specialists and workers are required. When choosing materials for a women’s winter coat made of woolen fabrics, you should rely on a scientifically based method.
The range of women’s outerwear is distinguished by diversity, due to the strict selection of the silhouette, proportions, quality and colors of materials. It can be a coat, short coat, demi-season and summer raincoat, bolero and others.
Relevant today are elongated coats, floor-length or knee-length, made of woolen fabrics with different pile heights, mostly lightweight with reduced material consumption. Fabrics are produced in one-colored, melange and variegated. The most winning fabrics for coats are all-wool fabrics using camel hair, llama wool, angora and cashmere goat wool.
The purpose of the course work is to consider a set of basic requirements for a product, like a package of clothes, to select a range of quality indicators, to formulate requirements for materials for the manufacture of women’s coats and to justify the correct choice of specific materials.
Requirements for a women’s coat.
A certain set of requirements is imposed on women’s coats, the most important are consumer and industrial. The former are due to the interaction and contact of clothing and a person in the process of wearing a coat, and the latter are due to the interaction of clothing with tools and labor force, the organization of labor in the flow.
Consumer requirements include functional, economic, aesthetic, environmental, social purpose, reliability and safety of consumption. Industrial requirements include design, technology, economics, and standardization.
Since the complex of consumer requirements for clothing depends on its purpose, conditions and seasonality of operation in a certain climatic zone, as well as on a number of other factors, at first the rank significance of the requirements is established for a women’s coat, i.e. one of the main requirements for clothing is singled out, and then the remaining requirements are ranked in order of importance.
Table 1. Rank dependence of the requirements for a women’s coat
|Name of clothes||Type of clothing||Seasonality of socks||Requirements|
Ergonomic requirements characterize the comfort and ease of use of clothing in the “man – product – environment” system. These include hygiene requirements that determine the microclimate in the undergarment layer (temperature and relative humidity, carbon dioxide content and air mobility), clothing parameters (correspondence of the coat design to the size and shape of the human body), ease of use of the product (putting on and taking off clothes) and ease of care. product (ease of washing and ironing, the use of individual elements of clothing – pockets, fasteners, etc.), here it is necessary to give the microclimate parameters in the undergarment layer and the mass of clothing that ensure good health and human performance at the proper level.
Aesthetic requirements characterize a beautiful appearance (preservation and stability of a given shape of the product throughout the entire service life, no pilling, low contamination, non-shrinkage, high color fastness, drape and crease resistance), compliance of the product with the trends of modern fashion for a certain season (according to the artistic and color design , weave pattern, shape and cut, the nature of the surface, the expressiveness of brand names), as well as the novelty, expressiveness and originality of the model.

|Coats, raincoats, jackets.||34.4||30-45||not > 0.08||not > 1.0|
Functional requirements characterize the conformity of the product to its purpose, age and size-weight group of consumers.
Reliability requirements determine the service life of clothing, its ability to maintain integrity, appearance and shape under operating conditions. The wear period of the coat is at least five years.
Environmental requirements characterize the level of environmental impact of emissions of harmful substances during the production and operation of a women’s winter coat.
Safety requirements determine the degree of safety and harmlessness for a person during the operation of clothing.
Economic requirements are due to the cost of purchasing a coat, the cost of caring for it and the duration of operation. Clothing should be affordable, taking into account the actual costs of its production and the real incomes of the population.
Design and technical requirements determine the conditions for mass production and obtaining a given form of clothing, the minimum consumption of material per unit of products and the reduction of waste when cutting materials.
