Flock - the specialized concept, of many languages meaning shortly cut textile fibres for drawing velvet coverings. Various technologies of flocking show different requirements to flowability, electroconductivity and jumping a flock. Depending on requirements to ready of a flocking product, a flock, during his(its) manufacture, special characteristics, for example are given: stability to mechanical influence, stability(resistance) influence of light (burning out), waters, solvents (excited environments), washing-up liquids, stability(resistance) temperature drops and much many other things. Manufacture of a flocking product which would meet showed requirements and at the same time would possess the comprehensible price, demands, alongside with optimum adjustment(option) of manufacture and a correct choice of electrospent glue, a careful choice of a flock of as much as possible suitable parameters.
History
Initial euphoria in relation to a flock in the textile industry in 50-60 years was replaced by disappointment. The reason consists in the following. Manufacturing of a flocking fabrics for the top lady's wear was the big business at the end of 50, and all wanted to enter him(it). The prices and quality have decreased, interest of manufacturers and buyers of clothes ослаб. At this time flocking materials everywhere were perceived as cheap substitutes classical nap and so it and was. Manufacture of a flocking carpet coverings, in the beginning, has stopped because of lack of technological knowledge of components, and later - because of lack of persistence of development of manufacture. In 60th years in Europe the flock has found a recognition at the advanced and flexible manufacturers of plastic and papers. Pragmatic Americans have accepted a flock not so quickly. In Asia (it is especial in Japan) a flock continued to use in the textile industry. Distribution in these markets has been achieved due to optimization of processes and a product. It is impossible to forget and the fourth market - less developed countries. Here too the flock that has been achieved due to lower requirements to quality was most advantageously used.
70th years have brought to Europe development of measuring and trial technologies for the initial materials, new pulses in textile branch and significant expansion of a scope; all this was accompanied by steady growth of manufacture. "Steady" it is not necessary to understand as a word constant. Certainly there were recessions in the middle 70 in America, Japan and Europe. Similar fluctuations were result of glut which conducted to reduction of price and qualities. Despite of all this, by the end 70 in the world the consumption level equal approximately 25000 t of pile in year has been achieved. Certainly, it is impossible to transfer(translate)this figure in square and running metres. Consumption of a flock for rolled materials makes 10-250 gr/m2, and at flocking piece products, structures the area of a surface is practically immeasurable. Thus, the quantity(amount) of the consumed pile is the unique way to show growth of manufacture. In 80th years growth proceeded. Again to the middle of decade recession, but this time only in the USA was. By the end 80 the level 50000 t in one year has been achieved. First half 90 has shown the further growth up to 60000 t. It is necessary to expect small recession in the middle of decade (considerably smaller, than in 70 or 80th years). His(its) reason consists not in loss of the market, and, that is the most probable, in transition of the major branches with high consumption of a flock to use of more thin microfibres. It will considerably lower superficial density of fibrous weight in gr/m2 at the same or a lot of square meters.
Flock
In the beginning 70 European industry has developed standards on quality of a flock and the uniform equipment for his(its) measurement and checks (Germany). At that time methods of check were widely used. The perfect methods which made possible the adaptation of characteristics of a flock to changing demand of the factories, to surrounding conditions and technology have been developed. Todaymany enterprises of branch have already received the certificate of quality ISO 9000 FF.
Adhesive
Flocking surface and a flock incorporate together a layer of glue which is rendered on a basis. In the textile industry it is possible to meet glues only on a water basis. Acrilic and PU dispersion and mixes allow to reach(achieve) high durability to damp and dry cleaning, and at the same time strong elasticity and softness of a fabric.
Flocking huge quantity(amount) of various surfaces. It is obvious, that cannot exist universal glues, suitable for all. For this reason manufacturers of glue offer various base recipes on a dispersive basis and on the basis of solvent. The basic recipes can be updated to approach(suit) a method of drawing (a brush, the platen, rakel, dispersion, etc.).
