Abstract
Description
Invenția se referă la un material nețesut ca strat inferior pentru huse din textură, pentru banchete destinate transportului de pasageri, în mijloace de transport rutiere, pe căile ferate sau aeriene.The invention relates to a non-woven material as a bottom layer for textured bags, for benches intended for the transport of passengers, by road, rail or air means.
Pentru a asigura confortul personalului care folosește bancheta, o banchetă cuprinde în mod general:To ensure the comfort of the staff who use the banquet, a banquet generally includes:
1) un suport care asigură confortul ergonomie al persoanei care folosește bancheta, suport care constă în general din material spongios dens, arcuri sau chingi ;1) a support that ensures the ergonomic comfort of the person who uses the seat, a support that generally consists of dense spongy material, springs or straps;
2) un strat din umplutură constând dintr-un material spongios, mai puțin dens decât cel care constituie suportul ( și eventual separat de suport printr-o membrană de separare);2) a filler layer consisting of a spongy material, less dense than the one constituting the support (and possibly separated from the support by a separation membrane);
3) o husă din textură.3) a textured cover.
Stratul de umplutură și husa din textură conferă aspectul și confortul termofîziologic. O banchetă construită în acest fel are o acțiune de izolație deosebit de bună, care înlătură transpirația persoanei care utilizează bancheta. Dacă această transpirație nu este evacuată repede atunci rezultă o senzație neplăcută de umiditate.The filling layer and the texture cover give the appearance and the thermo-physiological comfort. A bench built in this way has a particularly good insulation action, which eliminates the perspiration of the person using the bench. If this sweat is not released quickly then an unpleasant sensation of moisture results.
Efectul de izolație a banchetei este datorat, în principal, grosimii materialului spongios, dens, care constituie suportul membranei, care separă materialul spongios dens de materialul spongios de umplutură și de caracterul închis al materialului spongios de umplutură care conține un mare număr de bule de aer. Evacuarea umidității, datorată transpirației, din partea persoanei care stă pe banchetă nu este posibilă prin grosimea banchetei, deoarece blocul de material spongios, care constituie suportul, împiedică umiditatea să fie evacuată. De aceea, umiditatea trebuie eliminată fie prin laturi, fie prin ventilație, adică printr-o acțiune de pompare datorată mișcărilor și vibrației.The insulating effect of the seat is mainly due to the thickness of the dense, spongy material, which constitutes the membrane support, which separates the dense foam material from the foam filling material and from the closed character of the foam filling material that contains a large number of air bubbles. . Evacuation of moisture, due to perspiration, from the person sitting on the bench is not possible due to the thickness of the seat, because the block of foam material, which constitutes the support, prevents the moisture from being evacuated. Therefore, the humidity must be eliminated either by the sides or by ventilation, that is, by a pumping action due to the movements and vibration.
Problema tehnică pe care o rezolvă invenția este de a stabili componentele unui material nețesut, folosit ca strat inferior, înlocuitor al stratului de umplutură din material spongios la husa din textură a banchetei, care să aibă o rezistență la compresiune și o elasticitate adecvate pentru a permite absorbția umidității în mod rapid, transportarea umidității într-o direcție paralelă cu suprafața materialului și evacuarea umi dității prin ventilație.The technical problem that the invention solves is to establish the components of a non-woven material, used as a bottom layer, replacing the foam filling layer with the textured cover of the bench, which has adequate compressive strength and elasticity to allow moisture absorption rapidly, transporting humidity in a direction parallel to the surface of the material and evacuating moisture through ventilation.
Materialul nețesut ca strat inferior pentru huse din textură pentru banchete, confonn invenției, înlătură neajunsurile semnalate prin aceea că are o densitate aparentă deThe non-woven material as a bottom layer for textured covers for banquets, according to the invention, removes the shortcomings indicated by the fact that it has an apparent density of

Invenția prezintă avantajul că realizează absorbția rapidă , în zona de contact dintre persoana care utilizează bancheta și banchetă, a transpirației care emană de la această persoană.The invention presents the advantage that it achieves the rapid absorption, in the contact area between the person using the banquet and the banquet, of the sweat emanating from this person.
Caracteristicile suplimentare ale invenției vor reieși în cursul descrierii exemplelor de realizare ale invenției, aceste exemple nefiind în nici un fel limitative.Further features of the invention will be apparent during the description of the embodiments of the invention, these examples being in no way limiting.
Conform primului exemplu de realizare a invenției, materialul nețesut cuprinde un amestec de minimum 50% fibre tabulare de poliester cu patru canale legate termic, fibrele având finețea de 13 dtex, procentajul de volum gol fiind mai mare decât 23 % din volumul total al fibrei (DancronR QuallofilR D-291 produsă de Dupont de Nemours Company). Lungimea fibrelor este de 70...80 mm. O finisare specială dă acestei fibre o suprafață netedă, hidrofilă și un caracter de inflamabilitate scăzută.According to the first embodiment of the invention, the non-woven material comprises a mixture of at least 50% polyester tabular fibers with four thermally linked channels, the fibers having the fineness of 13 dtex, the percentage of empty volume being greater than 23% of the total fiber volume ( Dancron R Quallofil R D-291 produced by Dupont de Nemours Company). The fiber length is 70 ... 80 mm. A special finish gives this fiber a smooth, hydrophilic surface and low flammability.
Fibrele sintetice sunt alese de preferință din poliester, poliamidă și fibre de polioxiamidă, sau fibre de tipul superabsorbant, sau dintr-un amestec din aceste fibre.Synthetic fibers are preferably selected from polyester, polyamide and polyoxyamide fibers, or fibers of the superabsorbent type, or from a mixture of these fibers.
Prin fibre de tipul superabsorbant se înțeleg fibre având o capacitate de absorbție mai ridicată decât 100%, ceea ce înseamnă că sunt fibre care absorb mai mult decât 1 g apă/ g fibră.Fibers of the superabsorbent type are meant fibers having a higher absorption capacity than 100%, which means that they are fibers that absorb more than 1 g water / g fiber.
Fibrele superabsorbante utilizate sunt, de exemplu, acelea comercializate sub următoarele denumiri:The superabsorbent fibers used are, for example, those marketed under the following names:
- LansealR care este o fibră superabsorbantă de la Japan Exlan Co. Ltd. în care stratul exterior este din poliacrilat de amoniu superabsorbant, iar structura miezului ( aproximativ 70% în greutate) este fibră poliacrilonitrilică de tip standard. Finețea filamentului poate fi 3...5 den per filament;- Lanseal R which is a super absorbent fiber from Japan Exlan Co. Ltd. wherein the outer layer is made of superabsorbent ammonium polyacrylate and the core structure (approximately 70% by weight) is standard type polyacrylonitrile fiber. The fineness of the filament can be 3 ... 5 den per filament;
- FibersorbR (denumire actuală- Fibersorb R (current name
Fiberdri) care este un copolimer al anhidridei maleice făcut de Arco și comercializat de Camelot Superabsorbents Ltd. Finețea filamentului este de 10 den per filament; 5Fiberdri) which is a copolymer of maleic anhydride made by Arco and marketed by Camelot Superabsorbents Ltd. The filament fineness is 10 den per filament; 5
- BemlieseR care este o fibră celulozică accesibilă ca structură nețesută, cu finețea de- Bemliese R which is a cellulose fiber accessible as a non-woven structure, with the purpose of
3...7 den per filament3 ... 7 den per filament
Fibrele sintetice alese sunt în mod avantajos fibre din poliester. Fibrele utilizate 10 sunt, de preferință, hidrofile sau sunt făcute să fie hidrofile printr-un tratament adecvat.The synthetic fibers chosen are advantageously polyester fibers. The fibers used 10 are preferably hydrophilic or are made hydrophilic by appropriate treatment.
Fibrele sintetice incluse în compoziția materialului nețesut au o finețe între 3 și 40 dtex și, de preferință, 6 și 20 dtex și o 15 lungime între 2o și 120 mm și, de preferință, între 50 și 75 mm.The synthetic fibers included in the composition of the non-woven material have a fineness between 3 and 40 dtex and, preferably, 6 and 20 dtex and a length of 15 between 2 and 120 mm and preferably between 50 and 75 mm.
Materialul nețesut conține și până la 50% fibre naturale și/sau artificiale care pot fi, de exemplu, celuloză ( bumbac , mătase 20 artificială, viscoză ) sau fibre de lână.The non-woven material also contains up to 50% natural and / or artificial fibers which may be, for example, cellulose (cotton, artificial silk, viscose) or wool fibers.
Amestecul de fibre a fost dărăcit și scămoșat prin metode tehnice cunoscute de specialiștii în materie. Fibrele au fost apoi legate prin ace și apoi legate termic. Fibrele 25 legate termic sunt fibre ale căror punct de topire este inferior celui al fibrelor principale, sau fibre având un strat de suprafață al cărui punct de topire este inferior față de cel al părții interioare a fibrei (fibre din două 30 componente).The fiber mixture was chopped and sprinkled by technical methods known to those skilled in the art. The fibers were then tied through needles and then thermally bonded. Thermally bonded fibers 25 are fibers whose melting point is lower than that of the main fibers, or fibers having a surface layer whose melting point is lower than that of the inner part of the fiber (fibers of two 30 components).
Fibrele mai pot fi legate atât prin ace cât și chimic . Legarea chimică este efectuată prin stropirea fibrelor cu o rășină, care poate de exemplu să fie o emulsie apoasă de 35 poliacrilat sau rășină de poliuretan .Fibers can also be linked through both needles and chemically. Chemical bonding is performed by spraying the fibers with a resin, which may for example be an aqueous emulsion of polyacrylate or polyurethane resin.
Materialul obținut are o grosime de 10 mm și o densitate aparentă de 40 kg/m3.The obtained material has a thickness of 10 mm and an apparent density of 40 kg / m 3 .
El are o rezistență la compresiune astfel, încât dacă este supus la o presiune statică de 20 cN/cm2 (care corespunde presiunii exercitate de greutatea unei persoane medii), acest material reține o grosime de 8,5 mm.It has a compressive strength so that if subjected to a static pressure of 20 cN / cm 2 (which corresponds to the pressure exerted by the weight of an average person), this material retains a thickness of 8.5 mm.
Materialul nețesut, hi alte variante de realizare, poate reține o grosime minimă de 2 mm. Este avantajos ca această grosime minimă să fie de 4 mm.Non-woven material, with other embodiments, can retain a minimum thickness of 2 mm. It is advantageous that this minimum thickness is 4 mm.
Această grosime minimă de 2 mm sau chiar 4 mm este necesară pentru a permite materialului nețesut să absoarbă transpirația care emană de Ia persoana care stă pe banchetă și să transporte această umiditate într-o direcție paralelă cu suprafața materialului sau s-o transporte prin ventilație.This minimum thickness of 2 mm or even 4 mm is necessary to allow the non-woven material to absorb the perspiration that emanates from the person sitting on the bench and to transport this moisture in a direction parallel to the surface of the material or to be transported by ventilation.
Acest material nețesut a fost testat în comparație cu un material spongios standardizat pe un model din piele.This non-woven material has been tested against a standardized foam material on a leather model.
Parametrii testați sunt după cum urmează : rezistența termică R* ( măsurată în m2 K/w ), rezistența umidității la transport ( măsurată în m2 mbar/w ) și capacitatea de absorbție a umidității Fi ( exprimată în % ) și care reprezintă greutatea apei absorbite per greutate uscată a produsului. Acești trei parametrii au fost măsurați în condiții statice, adică prin supunerea materialului nețesut sau a materialului spongios la o încărcătură statică de 20 cN/cm2.The parameters tested are as follows: thermal resistance R * (measured in m 2 K / w), moisture resistance in transport (measured in m 2 mbar / w) and moisture absorption capacity Fi (expressed in%) and representing weight water absorbed by dry weight of the product. These three parameters were measured under static conditions, that is, by subjecting the nonwoven or spongy material to a static load of 20 cN / cm 2 .
Cei trei parametrii au fost măsurați și în condiții dinamice, adică prin supunerea materialului nețesut sau a materialului spongios la impulsuri de 20 cN/cm2 de două ori pe secundă.The three parameters were also measured under dynamic conditions, ie by subjecting the non-woven material or the spongy material to pulses of 20 cN / cm 2 twice per second.
Cel de-al patrulea parametru măsurat este rata de ventilație V, exprimată în %:The fourth measured parameter is the ventilation rate V, expressed in%:

Rtl în condiții staticeR tl under static conditions
Rezultatele acestor teste comparative sunt date în tabelele următoare:The results of these comparative tests are given in the following tables:
Se poate trage concluzia din aceste 15 tabele că deși materialul nețesut are o rezistență termică ușor mai ridicată, el are o rezistență a umidității la transport mai scăzută și o capacitate mai bună a absorbției umidității decât stratul de material spongios. 20The conclusion can be drawn from these 15 tables that although the non-woven material has a slightly higher thermal resistance, it has a lower transport moisture resistance and a better moisture absorption capacity than the foam layer. 20
Rata de ventilație ajunge la materialul nețesut la 32% (1,279 - 0,867/1,279 ) și pentru stratul din material spongios la 23 % (1,715 - 1,318/ 1,715 ), ceea ce înseamnă că efectul de vibrație și mișcare duce la o creștere mai 25 importantă a transferului de umiditate, în cazul materialului nețesut decât în cazul materialului spongios.The ventilation rate reaches the non-woven material to 32% (1,279 - 0,867 / 1,279) and for the layer of spongy material to 23% (1,715 - 1,318 / 1,715), which means that the effect of vibration and movement leads to a 25% increase. of moisture transfer, in the case of non-woven material than in the case of spongy material.
Materialul nețesut se leagă apoi cu un adeziv de husa de textură, prin unul din 30 procedeele tehnice cunoscute de specialiștii în materie, aceasta legătură adezivă poate fi efectuată, de exemplu, cu ajutorul unor mijloace adezive, cum ar fi o dispersie, o emulsie sau o soluție de adeziv, sau cu ajutorul unor 35 pulberi termoplastice, a unui film sau o acoperire. Acest mijloc adeziv poate fi, de exemplu, aplicat prin atomizare, stropire, impregnare sau piuarea materialului.The non-woven material then binds with an adhesive to the texture cover, through one of 30 technical procedures known to those skilled in the art, this adhesive bonding can be carried out, for example, by means of adhesive means, such as a dispersion, an emulsion or an adhesive solution, or with the aid of 35 thermoplastic powders, a film or coating. This adhesive means can, for example, be applied by atomizing, spraying, impregnating or peeling the material.
Conform celui de-al doilea exemplu de 40 realizare, materialul nețesut este alcătuit din 70% fibre care reprezintă un amestec de fibre poliesterice cu patru canale tubulare de tipul legat termic și fibre de poliester de 13 dtex, având lungimea de 70...80mm și finețea de 6 45 den per filament și 12 den per filament (fibre DacronR QuallofilR D-291 ) și 30% fibre polioxiamidice cu finețea de 1,9 dtex, 3,3 dtex, 6,7 dtex și 17 dtex și o lungime de 35...45 mm ( fibre VivrelleR produse de SNIA FIBRE). 50According to the second example of 40 embodiments, the non-woven material is made up of 70% fibers representing a mixture of polyester fibers with four tubular channels of the thermally bonded type and 13 dtex polyester fibers, having a length of 70 ... 80mm and fineness of 6 45 den per filament and 12 den per filament (Dacron R Quallofil R D-291 fibers) and 30% polyoxyamide fibers with fineness of 1.9 dtex, 3.3 dtex, 6.7 dtex and 17 dtex and o length 35 ... 45 mm (Vivrelle R fibers produced by SNIA FIBER). 50
Amestecul de fibre a fost cardat și înfășurat în conformitate cu procedeele tehnice cunoscute specialiștilor în materie. Fibrele au fost apoi legate prin ace și prin încălzire.The fiber mixture was carded and wrapped according to the technical procedures known to those skilled in the art. The fibers were then linked by needles and by heating.
