2.54

semi-bleached pulp

pulp bleached to an intermediate degree of brightness ( blue reflectance factor )

cf. bleached pulp , fully bleached pulp , unbleached pulp

2.55

semi-chemical pulp

pulp obtained by a combination of chemical cooking and mechanical treatment

Note 1 to entry: Among pulps of this classification are neutral sulfite semi-chemical pulp (NSSC pulp), high-yield kraft pulp , high-yield sulfite pulp , and caustic carbonate semi-chemical pulp .

2.56

shive

sliver of wood, or fibre bundle

[SOURCE:ISO 5350-1:1998]

cf. contrary

2.57

soda pulp

pulp obtained by treating the raw material with a liquor containing sodium hydroxide as the sole active agent

2.58

soda/chlorine pulp

pulp obtained by treating the raw material successively with sodium hydroxide and chlorine

2.59

softwood pulp

pulp obtained from the wood of coniferous trees

cf. hardwood pulp

2.60

solvent pulping

chemical pulping process in which the raw material is treated with an organic solvent, with or without additives, at high temperature and/or pressure to liberate cellulosic fibre

2.61

stickies, pl

diverse group of materials in disintegrated pulp that may adhere to objects at ambient temperature or may adopt adhesive characteristics when subjected to elevated temperature, elevated pressure or change of pH

Note 1 to entry: Adapted from ISO 15360-1:2000.

2.62

strawpulp

paper-making pulp obtained from cereal straws

2.63

sulfate pulp

chemical pulp obtained by cooking the raw material with a liquor containing essentially sodium hydroxide, sodium sulfides and possibly other components

Note 1 to entry: The term “ sulfate pulp ” is derived from the use of sodium sulfate as the source of sodium sulfides in the liquor-recovery process. In the strict technical sense, the term “ kraft pulp ” is more restrictive than “ sulfate pulp ”, and, in some countries, this distinction is also maintained commercially. In many countries, however, the two terms are regarded as synonyms commercially, the term “ kraft pulp ” being preferred in order to avoid confusion with “ sulfite pulp ”.

2.64

sulfite pulp

chemical pulp obtained by cooking the raw material with bisulfite liquor

2.65

theoretical commercial dryness

an arbitrary value that has been commercially accepted as the dry matter content of pulp

Note 1 to entry: It is 88 % or 90 % according to the country and/or commercial agreements.

Note 2 to entry: Adapted from ISO 801-1:1994.

2.66

thermomechanical pulp

TMP

mechanical pulp produced by a process in which wood chips are steamed, refined at an elevated temperature and pressure and finally subjected to secondary refining at atmospheric pressure

2.67

TMP

SEE thermomechanical pulp

2.68

unbleached pulp

pulp that has not been subjected to any treatment which is intended primarily to increase its brightness ( blue reflectance factor )

cf. semi-bleached pulp , bleached pulp , fully bleached pulp

2.69

wet pulp

pulp with a moisture content considerably higher than that of dry pulp

cf. dry pulp

2.70

woodpulp

pulp obtained from wood

Note 1 to entry: In French, the term “pâte de bois” is sometimes used to designate mechanical pulp .
