Filling composed of part of the plumage of waterfowl, especially geese. Down is an excellent thermal insulator, allowing the body’s natural perspiration, absorbing moisture and allowing it to evaporate slowly, providing an ideal microclimate for the body. Down is a hypoallergenic material: the mite, the main culprit in the spread of allergies, shuns down and prefers wool and cotton. It can withstand a pressure of 80,000 times its weight and return perfectly the same as before.

Down composed of part of the plumage of waterfowl. The down has the shape of a real flake, consisting of a central core (calamus) from which numerous barbs originate; it is the noblest part of the plumage, arises under the wings, on the belly and under the neck and performs functions of thermal protection. Down provides exceptional thermal insulation combined with great lightness: for example, 5-6 g of down is enough to fill a volume of 1 cubic decimeter, whereas wool and polyester need 2 or 3 times as much weight. From a physical point of view, heat containment depends on good insulation from the outside, which occurs primarily through air and secondarily through the inner material used. Down comforters are natural insulators par excellence because they have the ability to absorb and retain, in the form of countless chambers, large volumes of air. Down also offers high characteristics of resilience, compressibility and hygroscopicity, absorbing moisture and releasing it to the outside with significant physiological benefits to the human body.

The process is quite similar to that of molded polyurethane but, through the use of special molds developed by us, a leather-covered artifact can be obtained during molding.

The process is the same of the moulded polyurethane but, by using particular moulds developed by Poliform, the piece is covered with leather directly during the foaming process.

Filling composed of the fine feathers of acquatic birds, particuarly geese. Feathers have excellent thermal properties and allow the body to perspire normally, absorb humidity and allow it to evaporate gradually, thus creating the ideal microclimate for the body. Feathers are a material with natural anti-allergen properties: the dust mite, the principal agent for the spread of allergens, prefers wool and cotton to feathers. Feathers can withstand pressure up to 80.000 times its weight and return easily to its original shape.

Filling composed of the fine feathers of acquatic birds. Down has the form of a veritable floccule having a central nucleus (the calamus) from which the quill is formed. Down, the finest part of plumage, provides thermal insulation and is found under the wings, on the breast and around the neck. Down provides phenomenal heat insulating properties and is extremely lightweight. As an example, 5-6 grams of down are enough to fill a volume of 1 cubic decimetre, while wool and polyester require 2 to 3 times that weight. From a physical point of view, heat retention depends on good insulation from the outside, provided first by air and second by interior fill material used. Down is a superior naturally occurring insulator because it has the capacity to absorb and to retain large volumes of air in tiny chambers. Down offers excellent resiliency, displacement and hydroscopic properties, absorbing humidity and releasing it to the outside with significant physiological advantages for the human body.

Plant fiber made from the trunk of the cannabis sativa plant. Similar to linen in appearance and feel, hemp is the most moisture-resistant natural fabric.

Plant fiber made from the bamboo that envelops the seeds of plants of the genus gossypium. Cotton fiber has no electrostatic conductivity, does not felt, has very high hygroscopicity, does not irritate the skin, is hypoallergenic, and can be ironed at high temperatures. After linen and wool, cotton is the oldest textile fiber. The length of the fiber determines its quality: the longer it is, the more lustrous, durable and valuable cotton is.

Membrana di natura proteica ricavata dai bovini e sottoposta a trattamento per renderla inalterabile. Il processo è chiamato concia e consiste nell’eliminazione dello strato più superficiale e del tessuto connettivo sottocutaneo (ipoderma). Lo strato più importante è il derma, ed è costituito da fasci di fibre connettive ed elastiche. La parte superiore del derma, chiamata fiore, identifica il tipo di cuoio più pregiato che viene chiamato “Pieno fiore”.

A plant fibre derived from the stalk of cannabis sativa similar to linen in feel, it is the natural fibre that is most resistant to humidity.

A plant fibre derived from the bark of the genus corchorus. It is highly hydroscopic and the fibre is coarse and strong. The threads that are derived from the plant are coarse, stiff and very strong.

Velvet is a fabric whose cut threads are very evenly distributed, with a short dense pile giving it its distinctive feel. Velvet is woven on a special loom that weaves two pieces of velvet at the same time. The two pieces are then cut apart and the two lengths of fabric are wound on separate take-up rolls. Velvet can be made from many different kinds of fibres but silk and cotton are preferred.

A natural animal protein fibre derived from the cocoons of the mulberry silkworm (bombyx mori). Under the microscope, silk fibre is uniform, very similar to synthetic fibres. One of the specific properties of silk is the length of the filament: this can reach lengths of up to 700-800 meters. This makes it the longest fibre derived from an animal. There are four categories of silk textiles: taffeta, twill, satin and jacquard. Silk is the most splendid, softest and finest of natural fibres–cool in summer and warm in winter.

A textile can contain two or more types of fibres: for example, cotton and wool, wool and acrylic fibres, etc. These blended fabrics have varying characteristics depending on the fibres used and their proportions. Generally speaking, the blending of fibres allows the textile to retain the main properties of the fibres that comprise it. For example, a blend of cotton and synthetic fibres increases resistance to wrinkling.

These artificial fibres are derived by processing cellulose from various naturally occurring plants (the same plants that produce plant fibres), transforming and dissolving it using solvents and then forcing it through spinnerets to form a continuous thread or a floccule. This family of fibres includes: modal®, acetate, cupro, lyocell, and viscose. Synthetic chemical fibres are derived from organic substances that are blended then polymerised to form long molecular chains (macromolecules) that can be spun into continuous thread or floccules (discontinuous fibre). This family of fibres includes: acrylic, modacrylic, polyamide, polyester, polypropylene and polyurethane.

Regenerated fibre, obtained from wood chips and cotton spinning waste. It is extruded to form a continuous thread or floccule (also known as rayon). It has properties very similar to silk and, like most plant fibres, it is comfortable, durable (if kept dry) and is highly absorbent. It is used in blends with other natural or synthetic fibres.

A synthetic fibre that derives from a macromolecule composed of at least 50% acrylonitrile and is generally available in floccules. It is highly flame retardant and feels much like acrylic fibre to the touch. Moreover, it is resilient, shape retentive, fade and wash resistant, has a soft hand, is durable and dyes easily to bright shades, is chemical-resistant, easy to care for, insulating and non-toxic.

A synthentic fibre derived from a linear macromolecule that is a long-chain synthetic polyamide in which at least 85% of the linkages are attached directly to two aliphatic groups or rings. It can be used as a continuous thread or in floccules. The fibres are exceptionally strong, shape-retaining (excellent elasticity) and abrasion-resistant. It is easy to care for (washes, dries, does not require ironing), can be easily coloured or dyed and is wrinkle-resistant.

(Polyethylene terephthalate), a synthetic fibre derived from macromolecules composed of polyesters and is available in floccules or as smooth or volumised thread. Trevira® is one of the trade names under which it is sold. It is long-wearing, easy to care for and resists fading, humidity and microorganisms.

Hide is a protein material derived from the bovines and skins of cattle. Processing is referred to as tanning and consists of eliminating the outermost layer of skin and connective tissue (hypodermis). The most important layer is the dermis, consisting of fibrous fascicles of connective and elastic tissue. The upper portion of the dermis, called “grain”, is considered to be the highest grade of hide, called “full grain”.

Leather is a protein fabric derived from cattle and submitted to a tanning process. It is thinner and lighter than hide. General considerations. We give you some information that will help you to understand the characteristics of leather and hide listed below. The leather derives from the epidermis of the animals that is constituted by various layers and originally has a thickness of around 1 cm. Quality. When speaking of “full grain leather”, we consider the most superficial layer of the epidermis that maintains the natural characteristics of the grain, veneer and softness (more or less scarred). The dimension of the grain does not determine the quality of the leather, but it derives from aesthetical choices. In the case of more economic leathers, the inner layers are used and are manufactured to reproduce the natural characteristics of the leather (grinding and pressure moulding of the grain). Origin. The European origin of the leather is without doubt to prefer to exotic or overseas origins (which present more defectiveness due to scars and insect bites because of the breeding in the wild). Mineral tanning. The tanning, procedure that wants to preserve the leather from the natural organic decadence, is also used to exalt the softness, the colour, and the brightness of it. It is generally realized with chromium salts; only in the case of high quality leathers a vegetable tanning is realized in order to get the most natural effect. Dyeing. The dye that permits to get all the different colours starting from the natural one is done by immersion of the leathers in dye drums: we always use aniline, through dyeing the whole thickness (to be preferred to the superficial dyeing). Drying. The drying, generally made on frames in ovens, is done naturally at air for the finest leathers. Grain. The natural grain (not embossed) and the absence of grindings (a sort of smoothing) show the use of full-grain leather of a quality that does not need correction and retouch operations. Refinishing. The best final refinishing that then determines the aspect of the leather is the one finished with aniline, with a more natural aspect but also more delicate. The refinishing with polyurethane resins, instead guarantees great uniformity and resistance in the use. Thickness and dimension. A greater thickness determines a better leather and a greater dimension are to be preferred, as you have less waste in use.
