Tissue paper and toilet paper are used in daily life, which are mainly used for People’s Daily health, so it is usually called household paper in the paper industry, which is one of the indispensable paper species in people’s lives. Its shape is a single square, which is called square paper or facial tissue, and it is rolled into the shape of a roller, which is called roll paper.
They are usually made of cotton pulp, wood pulp, grass pulp, cane pulp, mixed pulp, waste pulp manufacturing, good quality toilet paper is made of native wood pulp, it is similar to the manufacturing process of general paper, but it is required to be made into extremely thin and fragile, so that the purpose is to rot when it encounters water, to achieve the purpose of environmental protection.
In general, tissue quality testing has 9 detection indicators: appearance, quantitative, whiteness, horizontal suction height, horizontal tensile index, vertical and horizontal average softness, hole, dust degree, microorganisms and other indicators. These indicators seem professional, but in fact, they are all perceived by you.
Shandong Drick Instrument Co., Ltd. has focused on paper testing instruments for 16 years, and the following is a simple toilet paper testing program.
Whiteness measurement
Toilet paper is not the whiter the better, it may be added to the excessive fluorescent bleach. Fluorescent agent is the main cause of dermatitis in women, long-term use may also cause cancer. How can you tell if there’s too much fluorescent bleach? First of all, it should be natural ivory white with the naked eye, or put the toilet paper under the irradiation of ultraviolet light (such as a banknote detector), if there is blue fluorescence, it proves that it contains fluorescent agents. Although the brightness is too low, it will not affect the use of toilet paper, but it shows that the raw materials used are poor, and try not to choose such products.
Whiteness Meter can measure the brightness (whiteness) of paper, cardboard and pulp (d/o), and also detect whiteness, fluorescence whiteness, ink absorption value, opacity, light scattering/absorption coefficient and other detection items according to international standards. There are LCD screen Chinese menu operation mode and digital tube display two different configuration options.
Water absorption testing
Drop water on the toilet paper and check the absorption rate. The faster the absorption rate, the better the water absorption.
Klemn Type Water Absorption Tester can be used to determine the capillary absorption rate of paper and board, and is suitable for unsized paper and board.
Transverse tensile index testing
The transverse tensile index is the toughness of the paper and whether it is easy to break when used. Pure wood pulp paper because of the long fiber, so the tension is large, toughness is good, not easy to break.
Tensile tester can be used to determine the tensile strength of paper and board (constant rate loading method), constant rate tensile test method. It is suitable for the determination of tensile strength, tensile strength, deformation rate and other properties of paper, cardboard, plastic film and other non-metallic materials.
Softness testing
Softness testing is an important index of toilet paper products, good toilet paper should give people a soft and comfortable feeling. The main reasons that affect the softness of toilet paper are the fiber raw materials and wrinkling process of toilet paper. Generally speaking, cotton pulp is better than wood pulp, wood pulp is better than wheatgrass pulp, and toilet paper with excessive softness feels rough to use.
Softness tester is used to measure the softness of paper, which is a test instrument that simulates the softness of the hand. It is suitable for the determination of the softness of high-grade toilet paper, tobacco sheet, non-woven fabric, sanitary napkin, facial tissue, film, textile, fiber fabric and other materials.
dust measuring
The dust degree is generally said to be more or less dust on the paper. If the raw material is log pulp, the dust level can generally meet the standard. However, if recycled paper is used as raw material, and the process is not appropriate, the dust level is difficult to meet the standard.
Dust measuring instrument adopts the method of measuring the dust degree of paper and cardboard, and determines the dust or fiber bundle under the standard observation environment stipulated by the state.
All in all, good toilet paper is generally natural milky white, or ivory color, uniform texture and fine, clean paper, no holes, no obvious dead pleats, dust, raw grass, etc., and low-grade toilet paper looks dark gray and has impurities, and the toilet paper will drop powder, color or even hair when touched by hand. Toilet paper manufacturers must control the quality!
