16.Limit oxygen index
The volume fraction of minimum oxygen content required to maintain combustion in an oxygen-nitrogen mixture after igniting the fibers.
17.Segment length
Segment length can be showed by the number of links. If the segment is shorter, there will be more units that can move independently on the main chain and the chain will has higher flexibility. On the contrary, the rigidity will be higher.
18.Bamboo fiber
It is the fiber obtained by extracting cellulose from bamboo.
19.Polymerization reaction
The reaction that the polymer is compounded by low molecular monomers
20.Conformation
It is the geometric arrangement and classification of atoms in the molecule in space formed by rotation within a single bond.
21.Hydrolyzed fiber
It refers to the cellulose that is hydrolyzed to a certain extent after acid action.
22.Cohesive energy
It is the total energy of 1 mole of molecules gathering together, which is equal to the total energy of the same amount of molecules separate.
23.Straightness
It is the ratio of natural length to stretched length.
24.Profiled fiber
In the spinning process of synthetic fibers, the fiber with non-circular cross section or hollow fiber that is spun by shaped spinneret holes is called profiled fiber.
25.Creep deformation
It refers to the phenomenon that the deformation of polymer gradually increases with the increase of time under a certain temperature and a small constant external force.
