A kind of sterile paper towel and its production process

Abstract

The invention discloses a sterile tissue and a production process thereof, and belongs to the technical field of tissue production. The tissue is prepared from, by weight, 20-60% of bleached sulfate softwood pulp, 30-70% of CPMP and 0-10% of broken paper pulp. According to the method, by adopting an appropriate principle and ratio, wet strength agents with low organic chlorine, biodegradable non-toxic fungicides and FDA-authenticated coatings, adopting forming equipment with a low vertical-horizontal tension ratio, a drying and sterilization process at the temperature higher than 40 DEG C andsafe non-toxic chemicals, and combining appropriate pressing printing processes, the produced tissue has the advantages of being low in quantification, low in vertical-horizontal tension ratio, sterile, environmentally friendly and high in water absorption performance.

Description

technical field [0001] The invention belongs to the technical field of paper processing, and in particular relates to an aseptic paper towel and a production process thereof. Background technique [0002] Toilet paper is a disposable sanitary product among household paper, also known as toilet paper. It has a roll shape or is folded into two folds, but most of them are three folds at present, mainly for hotels, guesthouses, office buildings, airports, and opera houses. , clubhouses and other public places for hand wiping, of course, also suitable for families; because there is no need to wait for the use of toilet paper, a piece of paper can dry one hand, leaving no hair dust on the hands after use, soft and comfortable, has gradually replaced The electric hand dryer in the bathroom has been very popular among the guests from the five-star hotel more than ten years ago to the current city coffee shop. [0003] 95% of China's household paper market is for personal consumptio...

Problems solved by technology

[0004] The production of domestic paper towels started late, with a low starting point, small production volume and narrow sales area. So far, nearly 50% of the products can not be regarded as paper towels that really meet the requirements. A domestic factory in Shijiazhuang, Hebei produced it in the mid-1980s. Since the first paper towel, the high-quantity wrinkle toilet paper standard has been used. Since the paper towel requires some specific physical indicators during processing and use, blind production cannot fully reflect the required product characteristics. In addition, the machine is mixed and the process is not good First, the quality is always uneven, let alone in line with international standards

Moreover, the existing paper towels have a higher quantitative range, with a quantitative range of 30-45g / m 2 , and at present, the production of paper towels is all produced on the rotary wire or short fourdrinier paper machine, the efficiency of the paper machine is low, and the energy consumption is high. The vertical and horizontal tensile force is relatively large, so in order to meet the horizontal tensile force, higher beating power consumption, dry strength agent and more wet strength agent are often used to meet the tensile requirement

And the existing paper towels also have more problems of bacteria and fungi
