Bro , thereThere are two reasons for friction  :-

  1. Interlocking
  2. Bonds or cold welding When an object is at rest it makes bonds with the surface and the irregularities on the surface of both of the objects get interlocked due to which the friction at that time is called static friction and has the highest friction force . But when you apply force and make the object to move then the bonds between them break down and the friction now is called kinetic friction which is due to only interlocking between the surface of two objects . The kinetic friction formula is normal × friction coefficient(which is constant ) so if you increase the force you don't change the normal force due to which the friction remains constant . Hope it would help you .
