Fashion can be defined as common tastes, temporary ways of living and feeling appropriate in a particular society. It can also be explained by saying that "it is the passion of people to seek change and introduce new forms".
Not only does fashion reflect historical periods, social societies can use fashion to distinguish themselves from other societies. Therefore, fashion symbols may differ according to class, status, occasion, age and gender.
Over time, changes occur in the characteristics of fabrics called patterns due to market demands, seasons and fashion trends. Fashion affects the fabric pattern, colors and overall appearance. However, fashion is also affected by raw material knitting and technological developments. Therefore, pattern and fashion are two concepts that form and are interconnected. Market demands and fashion also strongly influence fabric construction. In fashion trends in which loose and flowing clothing models are valid, the constructions are looser, and the constructions are tightened if tight and narrow patterns are in effect.
Economic conditions affect the constructions. It is thought that light weight fabrics created by using less raw materials will be economical. For this reason, it is the first solution that comes to mind that fabrics can be lightened by making them with fine yarns. However, Fine threads are expensive. In addition, the frequencies increase when fine thread is used. The important thing here is to create the optimal weight with thick yarns. Some features desired in appearance, such as gloss and hairiness, are provided by finishing processes. However, the construction features that will help these formations should also be used in the design.
The amount of expenditure made to perform production and service is called cost.
Costs depend on a wide variety of factors. Identifying these factors can assist in cost estimates and cost reduction efforts.
The raw material in the weaving process is yarn. The yarn is delivered by weight; Raw cloth is delivered in length and weight. Thus, the weight control of raw cloth types is also carried out. The yarn loses in the processes it goes through until it becomes a woven fabric. The percentage of yarn wastes and the proportion of defective piece cloths removed from the raw cloth affect the raw material cost in weaving. The raw fabric, which is taken to the finishing department, shrinks depending on the knitting type, yarn type and density in the pre-treatment, dyeing and finishing processes. These changes in the physical properties of the product should be taken into account in the raw material cost. In addition, defective parts come out of the finished fabric. This also affects the cost.
