What pulp is used for tissue?
Both Rottneros Mill and Vallvik Mill manufacture grades of pulp that are used for production of tissue paper. Groundwood pulp, CTMP (Chemi-Thermo-Mechanical Pulp) and long-fibre sulphate pulp can all be used to manufacture tissue paper.
What are the properties of pulp?

What are the different types of paper pulp?
Paper pulp have too many categories according to different methods. Specific categories are as follows: By processing, chemical pulp, mechanical pulp and chemi-mechanical pulp. By raw material, wood pulp, straw pulp, bomb pulp and waste paper pulp, etc.
Which pulp is used for manufacturing facial tissue paper?
Recycled pulp is safe to use as a raw material in paper manufacturing. Most of the facial tissues, toilet tissues and newsprints grade commonly contain 100% recycled pulp and in many other grades. Recycled paper is the kind of paper that was made from paper and paper products that have been used before and recovered.
What is pine pulp used for?
Conifers like pine and spruce are softwood trees. They have long fibres at a low density. The long fibres give it strength, so softwood pulp is often used to create sturdy products. Softwood also increases absorbency and is used for absorbent products such as paper towels, baby diapers and other hygiene products.
What is eucalyptus pulp used for?
Printing and writing paper. Decor paper. Paper for labels and receipts. Certain types of packaging paper.
How is pulp measured?
Record the total weight and subtract the base weight of the container. The difference between the two provides the weight of the dry pulp. Calculate the pulp density in terms of composition. Divide the weight of the dry pulp by the total weight of the slurry and multiply by 100.
What is the composition of pulp?
The dental pulp is composed by a gelatin-like material (proteoglycans and other glycoproteins), reinforced by irregularly arranged and interlaced collagen fibers. The primary function of pulp capillaries is to supply oxygen and nutrients to its constituent cells.
How many types of pulp are there?
3.1 Chemical Pulping The two main types of chemical pulp are kraft (sulfate) and sulfite, indicating the types of chemicals used. Most printing and writing papers, packaging, and paperboard are made from kraft pulp because of its superior strength and economics.
Which are 4 broad categories of pulping processes?
There are four broad categories of pulping processes: chemicaly semi-chemical, chemi-me- chanical, and mechanical pulping. These are in order of increasing mechanical energy required to separate fibers (fiberation) and decreasing reliance on chemical action.
What is toilet paper used for?
Toilet paper (sometimes called toilet tissue) is a tissue paper product primarily used to clean the anus and surrounding anal region of feces after defecation, and to clean the perineal area and external genitalia of urine after urination or other bodily fluid releases.
What are the different grades of pulp?
While some of our pulp grades provide strength and stiffness for our customers’ fibre mixes, others bring extra brightness or absorption. Our northern bleached softwood kraft (NBSK) pulp is prized for its strength and reinforcing properties; we offer two grades: standard and reinforced pulp.
How much pulp do I need for my Paper?
• Less than 10% mechanical pulp, normally 0% • Magazines, books, and commercial printing. • 70 g/m2 to 170 g/m2 for the finished sheet. • Needs exact color/whiteness, smoothness, ink receptivity, surface strength, stiffness Kraft Paper • Unbleached or bleached kraft pulp • 50 g/m2 to 134 g/m2.
What is pulp used for?
The printing and writing, and specialty paper industries use our pulp products to make coated and uncoated woodfree papers, graphic papers and specialty papers like labels, release liners and wallpaper.
Is there a difference between Wood and non-wood pulp performance for tissue paper?
Therefore, as far as the authors could ascertain, a comparison of wood and non-wood pulp performances for tissue paper application has not been fully reported, and in particular there has not been a simultaneous evaluation of all of the major tissue paper properties (strength, softness, and water absorbency).
