Clothing for motorcyclists comprising a knitted three-dimensional textile structure consisting of basalt yarns and covered with transpirable polyurethanes by coagulation.

Description

MOTORCYCLIST' S CLOTHING
DESCRIPTION
The present invention relates to a fabric structure particularly suitable for articles of clothing providing protection against heat and abrasion, for example for use as an article of clothing for motorcyclists, and to the relative production method.
Articles of clothing protective against fire and heat are required to provide adequate thermal protection and hence resist heat transfer from the surface of the fabric to the body.
Articles of clothing normally used by motorcyclists traditionally consist of cow hide dressed in such a manner as to form a natural protection which because of its specific preparation system also enables considerable comfort to be obtained. Those parts most exposed to impact on falling, such as knees, elbows, shoulders and hands, are also covered by special reinforced
supports including the use of rigid metal plates. During a fall, for a constant resting surface it can be observed that tearing consequent on the temperature developed by sliding leads to resultant burns on that part of the body involved. The weak point of the article of clothing is specifically the non- reinforced part of the dressed hide structure.
Articles of clothing are also known consisting of metal fibres and/or
synthetic fibres possibly treated with other materials to obtain particular characteristics, with results which are more or less satisfactory depending on the actual case. The choice of fibres or the type of treatment to which the fabrics are to be subjected is therefore of fundamental importance. An object of the present invention is to provide an article of clothing for motorcyclists presenting resistance to abrasion and to the consequent temperature developed.
Another object is to provide an article of clothing for motorcyclists which presents sufficient elasticity.
Another object is to provide an article of clothing for motorcyclists which is of sufficient transpirability.
These and further objects are attained according to the present invention by clothing for motorcyclists comprising a knitted three- dimensional textile structure formed from basalt yarns and covered with transpirable polyurethanes. These objects are also attained by a method for producing clothing for motorcyclists by means of a three-dimensional textile structure,
comprising the steps of producing said textile structure by knitting; using a basalt filament for producing said textile structure; and impregnating said textile structure with transpirable polyurethanes. Further characteristics of the invention are described in the
dependent claims.
The aforedescribed textile structure is able to provide suitable protection against sliding on falling from a motorcycle at high speed, and is able to resist abrasion and the temperature developed by
friction on asphalt. The elastic knitted fabric, as the support for subsequent compact coating with transpirable polyurethanes by a coagulation process, ensures elasticity and transpirability of the prepared article of clothing.
The characteristics and advantages of the present invention will be apparent from the ensuing detailed description of one embodiment thereof.
The term "knitted three-dimensional textile structure" means a non- run or circular textile structure able to provide elasticity to the
structure produced, in contrast to a loom-woven textile structure in
which the yarns meet perpendicularly, without providing the article with elasticity, and in contrast to non-woven fabrics in which there is no precise crossing order of yarns as in the two aforesaid categories, but merely a tangle of textile fibres. Knitwork produced by normal processes can be circular or non-run, and is made from a fibre able to resist transfer of the heat induced. These fibres, catalogued as flame retardant (F. R.), undergo a
reduction in intrinsic toughness if subjected to stress conditions favourable to the raising of temperature.
In contrast, basalt does not present these problems, and is the fibre chosen for the textile structure according to the present invention.
Basalt is a natural chemical compound formed from volcanic magmatic material; its chemical composition is such that after extraction, it can be melted and then extruded. In this manner continuous filaments are obtained in different sections, allowing spinning and weaving within certain limits. The basalt yarns used can be purchased from Basaltex or from "Plant of Insulation Material".
Basalt yarns are easily crushable because of their structure.
To obtain a knitted structure with basalt yarns the twisting method was used.
The basalt fibre is twisted for example with filaments of a modacrylic fibre which decomposes by carbonzation if brought into the vicinity of a flame.
The diameters of the modacrylic filament are chosen on the basis of the characteristics of the filament to be twisted.
Specifically, twisting is effected such that the modacrylic fibre winds the basalt filament in the form of narrow spiral turns. This twisting
gives the basalt filaments the necessary protection against breaking during the knitting operations. A coating process, specifically a particular treatment known as
coagulation, is carried out following weaving. This operation consists of impregnating a fabric with a transpirable polyurethane by foulard systems (polyurethanes of the
IMPRAPERM® and IMPRASIL® family produced by Bayer) selected
from a category suitable for the specific processing system, then
passing the combination through several baths containing water and dimethylformamide (a solvent specific for polyurethane). The concentration of the dimethylformamide in water is gradually reduced until only water remains, so that by virtue of its polarity the dimethylformamide in which the polyurethane is dissolved binds to the water while the polyurethane remains bound to the fabric.
The bond concerned is purely physical, however the polyurethane/fabric adhesion can be increased by establishing more
effective chemical bonds generally with known catalysts (for example catalysts pertaining to the isocyanate family).
Strength tests equivalent to demonstrating that which occurs during a
high speed fall were carried out using a mechanism consisting of a circular grinding wheel rotated at a standard speed equivalent to a large number of revolutions per second.
Knitwork samples comprising aramid (KEVLAR) fibres or other high toughness fibres demonstrate an almost instantaneous fall in their declared strength, with the formation of carbonized parts positioned
about the lacerations produced.
In contrast, the structures of the present invention, having a knitwork core of basalt fibre compacted with coagulated polyurethane, are able, for equal conditions, to withstand for a longer time the tests to which they were subjected.
The compacted structures produced provide a pleasant level of
comfort due to the formation of microcells and to their consequent
good transpirability, a specific characteristic of coagulated polyurethanes.
The knitted three-dimensional structure conceived in this manner is susceptible to numerous modifications and variants, all falling within the scope of the inventive concept; moreover all details can be replaced by technically equivalent elements.
