Medical cotton wool belongs to the category of the most demanded expendable material, which is used in a wide field. It is used during surgical operations in order to do sterile dressings. Also, the material is used for invasive medical or diagnostic activities. Depending on what this useful assistant is made of, its further range of application will depend. Some species that are marked GOST, are involved even for the implementation of cosmetic procedures.
The price of the presented consumables directly depends on how natural the composition turned out to be, as well as the method of processing the raw materials. The higher the class, the less risk for the patient to face with allergic manifestations or other variants of pathologies such as the inflammatory process. Good sterile cotton wool does not slow down the process of recovery, which has a beneficial effect on general health.
Raw materials for production
Despite the fact that most ordinary people still believe that they use cotton cotton only, this is far from the truth. Today, its production has stepped forward, using some other components as a basis.
The overall processing algorithm in any case remains identical, because in most cases it is still necessary to lay cotton fiber for the “foundation”. But now often there are viscose variations, or mixed types.
A few decades ago, each manufacturer was subjected to strict verification by the relevant services. They were forbidden to attract various additives. Since then, many consumers have thought that cotton is simply a specially treated cotton. But the current norms allow part of the composition to be replaced by synthetic or other natural components.
From the point of view of the developers of such a strategy, this allows to significantly reduce the cost of production, because of which its wholesale price will be insignificant. The most curious experts propose to purchase several bags of such material from different brands, and then at home to compare their structure. Usually, packaging from the outside does not disclose exhaustive information about the composition of the contents. To learn more, you have to grasp the small print on the back of the pack. And some unscrupulous manufacturers do prefer to hold back some of the important consumer information. They will give only a detailed study of the texture of the contents of the bag.
In total for the given question there are only three versions of the classification:
The first version is easy to distinguish by self-evident appearance. It is about long fibers, and also white color with a yellowish shade. The texture includes small peas.
The second modification is distinguished by a snow-white color, which sometimes gives a blueness. Shaking the contents of such a bag will fly dust. If the creaking is heard when pressing on the roll, it almost always indicates that it is not in favor of naturalness.
Usually manufacturers to achieve the perfect color palette attract optical brighteners, among which dioxin is the most popular. That he is considered one of the most potentially dangerous carcinogenic substances.
Regenerated counterpart are created on the basis of recycled materials. This is clearly indicated by the presence of yarn, which is a waste of textile production. Many are wondering what will happen if you shake a roll. Dust will also flow from it, as in the viscose alternative test. The color can be either pure white or with a slight bluish tint. It is usually delivered in rolls or large bales, and is used in a rather narrow list of areas of use.
Separately, the so-called kipinny variation is considered. This is a special surgical cotton, which sometimes can be found in the offices of cosmetologists. The distinctive characteristic of such a proposal involves the complete absence of various additives, synthetic components such as dyes or chemical bleaches.
Such precaution pays off due to the fact that the product is hypoallergenic. But to get it in a pharmacy just is unlikely to succeed. Hospitals and hospitals order it directly from the manufacturer in large quantities.
Having dealt with what classic and modern wool is made of, consumers believe that there are no other classifications for it. But in fact, all hygroscopic products of this kind have a separate sort according to their specific purpose.
The division is designed for three camps:
The first solution is different from other raw materials. Here they use only cotton fiber of the first grade. Due to this, it turns out to achieve optimal absorption and capillarity. In practice, this means that the consumables absorb moisture of any type well.
To achieve a similar effect, the authors attract only a long-stained look of cotton. The result will please the lack of specific "cotton wool".
Surgical offer has the highest degree of prochesa. Due to such scrupulousness, it turns out to neutralize even the smallest weedy components. No wonder she then easily absorbs, retains liquid and is well divided into layers after removal from the box.
Hygienic cotton wool passes when tested by the relevant authorities fewer stages of control. Some impurities are allowed here, even a synthetic component like bleach is not uncommon. Usually it is hygienic fillers that are found on the open market in a pharmacy. They may contain nodules or short fibers, as well as uneven whiteness.
But even the simplest cotton solution has a framework established by experts from the quality control service. For premium solutions, the requirements are more stringent, and include:
- The presence in the composition of only 100% organic cotton content.
- Lack of the lumps, unevenly located thick threads. Good consumables must quickly and easily exfoliate, as well as to be perfectly combed.
- But the small presence of nodules is a valid scenario.
- Pleasant textile sensations should be explained by the soft texture of the product.
- The color palette can fluctuate only within the limits of tolerances in cream shades. If the purchase has a too pronounced white tone, or there are blue tones, this indicates optical brighteners. People with sensitive skin should avoid such specimens so as not to run into urticaria or other manifestations of allergy.
- Absorption of moisture on the surface should be instantaneous. Flowing on a cotton ball indicates the abundance of non-natural components.
- The separation into layers occurs quickly and without considerable effort. Dust, as well as falling out short fibers, is also a sign of a poor-quality product.
- The unpacked purchase must be completely dry inside no matter what its final destination.
We should also test for suspicious odors. Real cotton doesn't have it, and adaptations with flavoring agents, or accompanying smells like caustic chemical or medicinal aromas are a bad sign.
How to get sterile material
If you want to create your own hands temporarily compression underwear, then for him take elastic bandages and non-sterile cotton wool. Such a tool is great for situations where the default contact of the material with an open wound surface is not provided.
The biggest difference between a sterile or non-sterile combination is the obligatory passing of the procedure of drying raw materials in a special furnace. So it turns out in a short time to destroy various pathogens. Then cleaned and decontaminated consumables are allowed to put even on open wounds without fear of possible infection.
Non-sterile solution does without auxiliary sterilization, and immediately after preprocessing it is sent to a packaging workshop. At the same time, the density of two representatives is practically the same.
Non-sterile combination is suitable for the following purposes:
On the basis of the presented view, the dressings are created on productions later on, and also used during manipulations associated with the beauty industry in aesthetic medicine centers. The discs, balls, sponges developed on the basis of them are then positioned as helpers for face and body care at home.
Attracting non-sterile material is allowed only in situations where the risk of infection is reduced to zero. Consumers like it due to its relatively low cost and the ability to absorb large amounts of liquid in seconds.
If you give a few minutes to study the instructions, you can also clarify whether chlorine was added to the composition as a bleach. Its absence is a pass to non-emerging skin irritation. But if a person swallows a piece of a ball or disk without exposure to chlorine, you should still consult a specialist.
Moreover, this should be done as soon as possible in order to avoid possible negative development of events and related complications.
Sterile specimens are certified and must also undergo a steam or chemical sterilization procedure. The result is well proven in the following situations:
- the production of dressings, which then will be in contact with an open wound surface or burn marks;
- manufacture of dressing material applied over the antiseptic treated area;
- if necessary, to prevent even the slightest percentage of the probability of infection.
This cotton wool has received a homogeneous structure, as well as a soft neck and a monochromatic color palette without blue streaks, because it is not allowed to attract any kinds of impurities. Sorption properties are greatly enhanced.
The basis for creating the usual pharmaceutical cotton wool is cotton wool, which has passed several processing stages.
First you have to collect it, which falls on the period of ripening of the fruits of the plant, representing unusual boxes. Over time, they open up, and inside you can see the soft fiber of light shades along with the seeds. It is this content that is considered the most valuable, that is why it is collected, handed over at special collection points, and then from there it is transferred to the ginnery.
Already in the factory, the collected primary source is first separated from the sown seeds, and also the fibers are divided according to length indicators. Standards for long fibers are at least 2.5 centimeters. Such "giants" are attracted to the manufacture of cotton fabric.
Short fibers in professional terminology are called lints. Just they are attracted to the production of cotton wool and the subsequent products from it.
Sometimes wool or even flax forms the basis for the product. Moreover, the last raw material is listed more common. But most manufacturers prefer to mix several types in order to achieve optimal technical and aesthetic characteristics. Especially often cotton-viscose combinations, which became one of the first versions of combinations of artificial and natural material, are found.
In the subsequent processing only cotton is used, which has been rated at least fourth grade. Best of all, if it is elastic and low-density cotton, which by structural distribution is more like wool.
The difference in the process is based on whether you need to create a filler for clothing, or for medical purposes. For traditional production, experts prefer clogged cartes. So called the basis, which during processing produces textile fibrous materials. For such purposes, short fibers are quite suitable.
First, the raw material is cleared of natural debris, attracting for this special dusty top. Also at the preliminary stage, particularly hard fibers are processed, which should be split during the passage of multi-drum tweaks.
The resulting result is cleaned, mixed, formed into canvases using factory presses and other equipment. At the beginning of the formation a fibrous mass is established without clear contours. It will have to be affected by a carding and felling machine to transform the shapeless something into a completely normal cotton wool eat. At this stage, a clear structure is determined according to the set parameters, as well as the preferred thickness.
Next, the semi-finished product passes quality control to eliminate the risks of manufacturing defects, after which it is pressed and packaged in bales. One such cube can pull on fifty kilograms. In this form, the material is sent further to the garment manufacturing factories, furniture factories or to other specialized enterprises.
Separately, we consider cases where it is necessary to create a completely clean product ready for practical use. In this situation, initially the mass is first loosened, and then sent to the cleaning and loosening machine.
After that comes the stage of cooking in an alkaline solution, which is obtained when the temperature is about to be elevated at about 130 degrees and at the correct level of external pressure. The final stage of purification involves the treatment of sodium hyposulphite.
The last step is needed to transform the physical fiber and neutralize the natural yellowish hue. An integral phase of cleaning is the removal of pectin and nitrogenous substances. The result will delight the whiteness.
If it is required to additionally provide cotton for operation with open wound surfaces, then it is sent to be sterilized. To do this, the furnace is heated to 125 degrees, setting the pressure bar at the boundary of 3 atmospheres.
Part of the resulting product is packed and transported to warehouses, and the remaining half is immediately put into circulation. We are talking about the production of cotton swabs for cleaning hard-to-reach places. Separately, there is a category of cleaning cotton products exclusively for technical purposes, and not hygienic, which reduces their cost.
The issue of wadded suits, the density of which is somewhat higher than that of the porous standard source, is considered separately. Consumers highly appreciated such an assistant in applying and removing makeup due to the fact that when soaking it does not significantly change its shape.
Regardless of the ultimate goal of operation, experts advise choosing cotton wool without chemical additives, if you plan to touch it to the skin, even if it is not an open wound surface.
