Tissue paper has become a necessary daily necessity in people's lives, and the quality of tissue paper also directly affects people's health. So, how is the quality of paper towels tested? Generally speaking, there are 9 testing indicators for tissue paper quality testing: appearance, quantitative, whiteness, transverse absorbent height, transverse tensile index, longitudinal and transverse average softness, holes, dustiness, microbiological and other indicators. The quality of paper towels is determined by testing. So how do you test paper towels? In this article, we will introduce the detection method of paper towels and the 9 detection indicators.
First, the detection index of paper towels
1, appearance
The appearance of paper towels, including the appearance of the outer packaging and paper towels. When selecting paper towels, you should first check the packaging. Packaging seal should be neat and firm, no breakage; packaging should be printed with the name of the manufacturer, date of production, product registration (superior, first-class, qualified products), using the standard number, the implementation of the health standard number (GB20810-2006) and other information.
Secondly, is to check the appearance of the cleanliness of the paper, whether there are obvious dead folds, mutilated, broken, rigid block, raw grass tendons, pulp mass and other paper diseases and impurities, paper use whether there is serious hair loss, powder phenomenon, whether there is residual printing ink.
2、Quantitative
That is, the portion or the number of sheets enough. According to the standard, the net content of 50 grams to 100 grams of goods, the negative deviation shall not exceed 4.5 grams; 200 grams to 300 grams of goods, shall not exceed 9 grams.
3, whiteness
Tissue paper is not the whiter the better. Particularly white paper towels may be adding an excessive amount of fluorescent bleach. Fluorescent agent is the main cause of female dermatitis, long-term use may also cause cancer.
How to identify whether the fluorescent bleach is excessive? Preferred with the naked eye should be natural ivory white, or put the paper towel in the ultraviolet light (such as money detector) under the irradiation, if there is blue fluorescence, it proves that contains fluorescent agent. The bright white over low although it does not affect the use of paper towels, but the use of raw materials is poor, also try not to choose these products.
4, water absorption
You can drop water on it to see how fast it absorbs, the faster the speed, the better the water absorption.
5, lateral tensile index
Is the toughness of the paper. Whether it is easy to break when used.
This is an important indicator of tissue paper products, good tissue paper should give people a soft and comfortable feeling. The main reason affecting the softness of tissue paper is the fibre raw materials, wrinkling process. Generally speaking, cotton pulp is better than wood pulp, wood pulp is better than wheatgrass pulp, softness exceeds the standard of tissue paper used to feel rough.
7, hole
Hole indicator is the number of holes on the wrinkled paper towel limited requirements, holes will have an impact on the use of paper towels, too many holes in the wrinkled paper towel is not only the appearance of the poor, in use, but also easy to break, affecting the effect of wiping.
8, dustiness
Common point is that the paper is dusty or not. If the raw material is virgin wood pulp, virgin bamboo pulp, dust degree is no problem. But if you use recycled paper as raw materials, and the process is not appropriate, the dust degree is difficult to meet the standard.
In short, good tissue paper is generally natural ivory white, or unbleached bamboo colour. Uniform and delicate texture, clean paper, no holes, no obvious dead folds, dust, raw grass tendons, etc., while the low-grade paper towels look dark grey and impurities, with a touch of the hand will be powder, colour and even hair loss.
