In the past, softeners were mainly used in the treatment of textiles, and rarely in the processing of paper and its products. However, when people treat paper for other purposes, it also improves its softness, such as glycerin added in cellophane production, and waterproofing agent added to waterproof paper, which also plays a role as a softener.
In recent years, the consumption of disposable household paper such as paper handkerchiefs, toilet paper, napkins and diaper paper is increasing, and the requirements for paper quality are getting higher and higher, especially for paper softness, so paper softeners have received more and more attention. The purpose of using paper softener is: to reduce the binding force between fibers, reduce the rigidity of the paper, and reduce the friction of the paper on the first fiber; It has the effect of wetting fibers, improving the smoothness of fibers, and increasing the smooth and delicate feeling of paper; Make the paper malleable.
In short, the softener can form a hydrophobic base on the surface of the fiber to reverse adsorption, reduce the dynamic and static friction factor of the fiber substance, so as to obtain a smooth and soft feel. In fact, in addition to the softening effect, the softener sometimes has waterproof, anti-re-pollution, antistatic and other effects.

Soft paper is a paper product that is commonly used in areas such as facial tissue or toilet paper. It is characterized by softness, skin-friendliness, strong water absorption, etc. Compared with rigid paper such as ordinary printing paper, soft paper is not only used in hygienic fields, but also in some business fields with high hand feel requirements, such as makeup paper, cigarette packaging inner layer, etc.
Soft paper is usually made of raw materials such as high-quality wood pulper manuscript paper or recycled paper, and its processing process includes pulp preparation, pulp manufacturing, correcting paper processing, paper quality inspection and other links, among which pulp preparation and pulp manufacturing are the key links in soft paper production, which affect the quality and function of soft paper. It is worth mentioning that some chemical ingredients such as skin care and antiseptic are usually added in the manufacturing process of soft paper, so special attention should be paid to some people who are sensitive to paper materials, such as allergies.
In addition to the above basic introduction, the field of soft paper also involves the expansion of some technologies and applications. For example, under the current trend of environmental protection, some hard paper manufacturers have also begun to turn to the production of soft paper to meet the requirements of environmental protection and consumer demand at the same time. In addition, in the production process of soft paper, in recent years, many enterprises have put forward new technologies and concepts, such as "non-woven" manufacturing technology, material degradation, etc., which can improve the quality and environmental performance of soft paper.
In summary, soft paper is a soft, skin-friendly, and highly absorbent paper product, which has a wide range of uses, in addition to being used in the hygiene field, there are also cosmetics, cigarette packaging inner layers and other businesses. The manufacturing process of soft paper is complex, requiring attention to quality control and preventing excessive chemical addition. With the improvement of environmental protection concepts, the technology and application in the field of soft paper are also expanding.

Summary. What kind of paper is soft paper?
Hello, very happy to answer the question for you, soft paper is to buy new shoes, next to the inside of the shoes, or to prevent fragile utensils from breaking the fill, the kind of thin, very soft paper.
The thin, soft paper used for drawing is sulfuric acid paper.
Sulfuric acid paper is very hard.
If it's for drawing, I recommend using rice paper. Xuan paper is divided into false traces of raw Xuan empty leakage, semi-cooked Xuan, and cooked Xuan. The difference is strong in water absorption and water absorption, and it is easy to produce rich ink rhyme changes, so it can collect water and ink and achieve the artistic effect of water and ink retention.
Freehand landscapes use it more.

Nickel plating additives are generally divided into three components: brightener, softener, and wetting agent, and the three things play different roles.
The softener reduces the brittleness of the plating, generally the primary bright spike splitting agent, the main component is sodium saccharin, and the wetting agent reduces the surface tension of the plating solution to prevent the hydrogen generated during electroplating from adsorbing on the surface of the workpiece and causing pinholes.
The softener generally needs to be used with a brightener.

Softness is for fibers, surfactants can form a hydrophobic group on the surface of the fiber to reverse adsorption outward, reduce the dynamic and static friction factors of the fiber substance, and obtain a smooth and soft feel by macrosliding. Surfactants and oils are usually used together, surfactants can effectively reduce the static friction factor of fibrous substances, and oil agents can reduce the dynamic friction factors of fibrous substances. The effect of soft lubrication can be expressed by the difference between the static friction factor and the dynamic friction factor, and the smaller the difference, the stronger the flexibility.
Different types of softeners are suitable for different types of fiber surfaces. The surface of the paper fiber is negatively charged, and the masking effect with cationic or zwitterionic surfactants is much better. In addition to surfactants, lipids such as silicone polymers or lanolin are generally added to the formulation of softeners and smoothing agents to fully reduce the surface energy of fibers.
Among the softeners, silicone surfactants and silicone polymers have the best effect, but the raw materials are high**, and they are often used in combination with other soft components to reduce costs. Foreign products include the British ICI company's velan products belong to the fatty phenolamine cationic surfactant, the United States DuPont Chemical Company's Zelan products also belong to the cationic surfactant, at the same time, the organosilicon polymer surfactant has a good soft effect, and has also begun to be gradually applied in the paper industry. At present, the main varieties in China are alkyl imidazoline quaternary ammonium salts, silicones, polyethylene oxide, etc., of which except for polyethylene oxide, the rest are basically used as substitutes for textile softeners.

The food soft agent can be used for starch complexation, directly connected with the amylose in the starch to form a spiral complex, so as to reduce the degree of crystallization of the starch wax clump molecule, and enter the starch granules to prevent the condensation of amylopectin, so as to prevent the aging, regeneration and coagulation of starch products. The addition of softener can complexate with flour protein, strengthen the gluten network structure, increase toughness and tensile strength, maintain the softness of the product, inhibit water evaporation, increase the volume, and improve the taste.

Softener. It is a class of chemical substances that can change the static and dynamic friction coefficients of fibers. When changing.
Coefficient of static friction.
, the touch is smooth, and it is easy to move on fibers or fabrics; When the coefficient of dynamic friction is changed, the fine structure between the fiber and the fiber sail is easy to move with each other, that is, the fiber or fabric is easy to deform. The combination of the two is softness. According to ionic properties, soft twigs are divided into cationic, non-ionic, anionic and amphoteric types.
Quaternary ammonium salt state failure.
There are four types.

Soft finishing is an important finishing process in printing and dyeing processing. During the processing of textiles, the feel will become rough after multiple treatments, and synthetic fiber fabrics are generally worse, especially microfiber fabrics. In order to make the fabric have a soft, smooth and comfortable feel, it needs to be finished, and the widely used is to finish with a softener.
In addition, a large number of softeners are used in the spinning and weaving processes of chemical fibers, because with the large use of high-speed and small liquor ratio in textile processing, the friction between fabrics and between fabrics and equipment increases, and it is easy to produce abrasions, stripes and other phenomena. The use of softeners allows the fibers themselves to have a softness and smoothness that is compatible with the processing conditions to avoid damage. Therefore, fabric softener is an important textile auxiliary.
Various new fibers such as microfiber have been widely used, and with the gradual improvement of people's awareness of environmental protection, all kinds of Huailun softeners and their main components have been further improved.
