Abstract

A piece of woven fabric cut to production size for the manufacture of articles of work clothing for protection from heat, flames, and electric arc effect is characterized by a 3/1 frame casing having approximately 36 threads per centimeter of chain and approximately 23 threads per centimeter of weft. The overall mixtures of chain yarn and weft yarn are approximately 41 percent viscose, approximately 30 percent to 41 percent meta-aramide, approximately 17 percent to 29 percent paramide, and approximately 1 percent polyamide with a carbon core, and by doubled yarns with count No. 40/2.

Description

Die Erfindung bezieht sich auf ein Gewebe zur Herstellung von Arbeitsbekleidungsstücken zum Schutz gegenüber Hitze-, Flammen-, Lichtbogeneinwirkungen und dgl.The invention relates to a fabric for manufacture of work clothing to protect against heat, Flame, arc effects and the like

Für Schweißer besteht schon seit längerer Zeit das Bedürfnis, Materialien für Schutzbekleidungsstücke zu entwickeln, die nicht nur den einerseits sehr hohen Beanspruchungen, hinsichtlich der Schwerentflammbarkeit beispielsweise, standhalten, sondern darüber hinaus auch einen hohen Tragekomfort bieten. Hinzu kommt noch, daß diese Kleidungsstücke für industrielle Betriebe gedacht sind, d.h. dort dem Personal für eine kurze Zeitspanne zur Verfügung gestellt werden, danach gereinigt werden und wieder zum Einsatz kommen sollen, wobei eine hohe Zahl derartiger Einsätze gefordert wird. Eine lange Lebensdauer ist also eine wichtige Forderung, wobei während dieser Zeit die einschlägigen Prüfvorschriften erfüllt werden müssen.This has existed for welders for a long time Need to materials for protective clothing too develop that not only the very high one Stresses with regard to flame retardancy for example, withstand, but also beyond offer a high level of comfort. Add to that this Garments are intended for industrial companies, i.e. there for the staff for a short period of time be put, then cleaned and back to the Should be used, a large number of such Operations is required. So is a long lifespan an important requirement, during which the relevant test regulations must be met.

Bislang für diesen Zweck vorgesehene Materialien konnten nie alle Bedingungen der Prüfvorschriften erfüllen und zugleich einen hohen Tragekomfort sicherstellen. Vorwiegend hitzestabile Kleidungsstücke waren von sehr geringem Tragekomfort für die geschützte Person selbst. Hierbei ist zu berücksichtigen, daß die Hitzeeinwirkung selbst schon eine Belastung für die arbeitende Person darstellt.Materials previously intended for this purpose could never meet all the conditions of the test regulations and at the same time ensure a high level of comfort. mainly heat-stable garments were of very little Comfort for the protected person himself to take into account that the heat exposure itself represents a burden for the working person.

Zu den typischen Erfordernissen, die das Gewebe bzw. ein daraus hergestelltes Kleidungsstück erfüllen müssen, gehören:

  • 1. Erfüllen von thermischen Beanspruchungen durch Kontaktoder Strahlungshitze sowie offene Flamme.
  • 2. Sicherheit gegenüber Funken und mit hoher Geschwindigkeit fliegenden Kleinteilen aus glühendem Metall, verursacht z.B. durch Schweißen, Schneiden, Flexen.
  • 3. Schutz gegenüber der Einwirkung von Lichtbögen durch elektrische Entladungen.
  • 4. Erfüllung mechanischer Beanspruchung durch scharfkantige Gegenstände z.B. Metallbleche.
  • 5. Widerstandfähigkeit gegenüber Beanspruchungen durch industrielle Behandlungen bei der Reinigung und zur Wiederherstellung der Schutzwirkung (Waschen - Trocknen - Dekontamination).
  • 6. Erreichen eines hohen physiologischen Tragekomforts.
    • The typical requirements that the fabric or a garment made from it must meet include:
  • 1.Satisfaction of thermal stresses through contact or radiant heat as well as open flame.
  • 2. Security against sparks and small parts made of glowing metal flying at high speed, caused for example by welding, cutting, flexing.
  • 3. Protection against the effects of arcing through electrical discharges.
  • 4. Fulfillment of mechanical stress by sharp-edged objects, eg metal sheets.
  • 5. Resistance to stress caused by industrial treatments during cleaning and restoring the protective effect (washing - drying - decontamination).
  • 6. Achieving a high level of physiological comfort.

    • So ist z.B. eine Schutzbekleidung aus einer Hose und einer Jacke bekannt (DE 91 01 311 U1), die den Träger gegen Flammeneinwirkung schützen soll und zu diesem Zweck gegen elektrische Körperdurchströmung und Einwirkungen von Störlichtbogen eine erste äußere Schicht aus flammenhemmendem Gewebe, eine zweite wind- und wasserdichte jedoch wasserdampfdurchlässige Sperrschicht gegen Stromdurchgang, eine dritte schwer entflammbare, elektrische Sperrschicht und eine vierte innerste Innenfutterschicht aufweist. Eine derarige Schutzbekleidung ist, wenn überhaupt, nur im Elektrobereich einsetzbar und bietet für den Träger einen nur geringen Tragekomfort.For example, protective clothing consisting of a pair of pants and one Jacket known (DE 91 01 311 U1), which the wearer against Flame should protect and against this purpose electrical flow through the body and effects of Arcing arcing a first outer layer flame retardant fabric, a second wind and waterproof however water vapor permeable barrier layer against Continuity, a third flame-retardant, electrical Barrier layer and a fourth innermost lining layer having. Such protective clothing is when at all, can only be used in the electrical sector and offers for the wearer is only slightly comfortable.

    Zur Erhöhung des Tragekomforts von Schutzbekleidungsstücken für Feuerwehrleute ist ein Textilmaterial für das Innenfutter bekannt (DE 44 08 141 A1), bei welchem von Multifilament-Aramidgarnen ausgegangen wird. Die für Schutzbekleidungen relevanten Eigenschaftswerte können jedoch nach mehrmaligem Reinigen des bekannten Innenfutters nicht eingehalten werden.To increase the comfort of protective clothing for firefighters is a textile material for the Lining known (DE 44 08 141 A1), in which of Multifilament aramid yarn is assumed. The for Protective clothing can have relevant property values however, after cleaning the known inner lining several times are not adhered to.

    Der Erfindung liegt das Problem zugrunde, alle vorangehend genannten Erfordernisse durch ein Gewebe sicherzustellen, insbesondere nämlich auch dann, wenn das Kleidungsstück schon viele Male gereinigt worden ist.The invention is based on the problem, all of the foregoing to ensure the above-mentioned requirements with a fabric, especially when the garment has been cleaned many times.

    Erreicht wird dies durch die in den Ansprüchen angegebenen Materialien, Eigenschaften und Strukturen, zu denen hier nachfolgend Ausführungsbeispiele angeführt werden.This is achieved by those specified in the claims Materials, properties and structures to which here Examples are given below.
