Волокна и ткани в текстильной промышленности. Биева Е.Г. - 21 стр.

      Wool fibres are quite different in form and composition from cotton and linen. Raw wool
contains a high proportion of impurities which are removed by a scouring process before
spinning and weaving will be carried out.
      Most wool fabrics and garments shrink when washed for the first time. With additional
washings further shrinkage takes place and this is accompanied by a matting or felting. Felting
continues with further washing until the fibres are packed to a maximum degree in the fabric.
      Although wool is the most important animal fibres, there are other hair fibres which are
of considerable commercial value. These come mostly from animals of the goat and camel
families.
      The Angora goat, which originated in Turkey, has a coat of long, lustrous hair. This hair
provides the textile fibres known as mohair.
      Camel hair is also used as a textile fibre. Camel hair fabrics are warm and comfortable.
They are used for making overcoats, dressing gowns and knitted goods.
      Llama, alpaca, guanaco belong to the camel family.
