Definitions
- the present invention relates to a high abrasion resistant fibrous structure comprising a specific construction of a non composite p-aramid strand and a nylon strand.
- This structure can be used to manufacture protective clothing having a high cut resistance and a high abrasion resistance.
- Aramids and more specifically para-aramids are a relatively new class of materials, which finds application in the domain of mechanical and thermal protection. High cut protection performance can be obtained from textile assemblies made of the para-aramid fibers. Therefore, para-aramid fibers are often used in the manufacture of protective clothing for industrial workers, firemen, sportsmen, military and police officers.
- para-aramid fibers tend to suffer from a relatively low abrasion resistance due to their fibrillation tendency.
- the risk associated with this modest abrasion resistance is the reduction of the cut performance of the protective clothing with time under service.
- nylons are superior but they do not offer a sufficient cut performance.
- abrasion resistance of a fabric There are many factors that influence the abrasion resistance of a fabric.
- the abrasion performance may be tailored by the selection of the type of fiber components, the fiber properties, the textile structures, the fabric mass per unit area, the number of fibers per unit volume or the relaxation allowance of the fiber components within the fiber bundle.
- the addition of abrasion resistance materials in a given structure containing cut resistance components generally provides higher abrasion performance at the expense of the cut resistance.
- U.S. 5, 319, 950 discloses a reinforcing component which is a composite yarn made of a nylon twisted yarn helically wrapped by another nylon twisted yarn, this reinforcing component being knitted in a plaited relationship with a body yarn. The manufacture of such a yarn is complex and necessitates several steps. Moreover, the reinforced fabric thus obtained is still not satisfactory as regards cut resistance.
- One aspect of the invention is a fibrous structure comprising at least one non composite para-aramid strand and at least one nylon strand maintained in a parallel relationship to each other, the non composite para-aramid strand being present in the structure in an amount ranging from about 20 % to about 99.9 % by weight, relative to the weight of the structure.
- Another aspect of the invention is a process to manufacture the structure above comprising the step of processing a non composite para-aramid strand and a nylon strand in a parallel relationship to each other.
- Another aspect of the invention is a process for providing a fibrous structure having high cut and abrasion resistance, comprising:
- a further aspect of the invention is a high cut and abrasion resistant protective clothing, in particular gloves, aprons or sleeves, made of the fibrous structure above.
- the fibrous structure of the invention has a high resistance to abrasion. It also has a very high resistance to cutting. With the structure of the invention, it is possible to manufacture high cut and abrasion resistant protective clothing like working gloves.
- the gloves made of the fibrous structure of the invention are comfortable and, by wearing them, the user does not lose the natural dexterity of his hands.
- the fibrous structure of the invention also finds use in the ballistic area: it has a very good puncture resistance. Moreover, since the para-aramid strand of the invention is a non composite one, the manufacturing process of the fibrous structure is very simple and direct and does not require any previous treatment or arrangement of the strand. The manufacturing process can therefore be completed in a minimum number of steps, allowing for a rapid, easy and cost effective realization of any fibrous structure.
- Fibrous structure includes two or three- dimensional structures comprising fibrous material.
- this structure includes knitted fabrics, woven fabrics, unidirectionals, nonwovens, and/or combinations thereof.
- combinations is meant that structures of different nature and/or construction may be assembled together, either in the same plane or not, as a multilayer structure for instance, by any assembling means like sewing, gluing, stitching and the like.
- nonwovens is meant fibrous materials combined to a binding matrix of polyethylene, polypropylene, polyamides, phenols, epoxy resins, polyester or mixtures thereof.
- Fibrous material includes endless fibers such as filaments, short fibrous structures, short cut fibers, microfibers, multifilaments, cords, yarns, fibers, pulps.
- the fibers may be made into yarns of short fibrous structures which are spun into staple fibers, into yarns of endless fibers or into stretchbroken yarns which can be described as intermediate yarns between staple and continuous yarns.
- “Strand”, as used herein, means an ordered assemblage of fibrous material having a high ratio of length to diameter, preferably having a length at least 1000 times its diameter.
- the strand may be round, flat or may have another cross-sectional shape or it may be a hollow fiber.
- non composite strand is meant a single simple strand by opposition to assembled strands like cotwisted strands, cotextured strands, intermingled strands, core-spun strands and combinations thereof.

- Preferred process for making the structure of the invention is the knitting process.
- the structure of the invention may be used in the manufacture of gloves, aprons, sleeves and any protective clothing requiring a high cut resistance and a high abrasion resistance.
- the abrasion resistance of the samples was measured according to the Standard European Method EN388, July 1994, section untitled “Protective Gloves against Mechanical Risks", subsection 6 "Abrasion resistance”.
- the apparatus was the Martindale wear and abrasion tester, designed to give a controlled amount of abrasion between the fabric surface and the selected abradant at relatively low contact pressure of (9 +/- 0.2) kPa in continuously changing directions.
- the circular samples were abraded against a standard abrasive glass paper (grade F2 grit 100 quality 117).
- the abrasion was continued and the samples were examined at suitable intervals without removing them from their holder.
- the rub-through situation was characterized by broken threads and the average values of cycle to reach this breakdown was registered and averaged for 6 samples.
- the test is conducted at (23 +/- 2) °C and (50 +/-5) % relative humidity.
- the cut resistance was measured according to the "Standard test Method for Measuring Cut Resistance of Materials Used in protective Clothing", ASTM Standard F 1790-97.
- a cutting edge under a specified force, was dravx n one time across a sample mounted on a cylindrical mandrel.
- the distance drawn from initial contact to cut through was recorded and a graph was constructed of force as a function of distance to cut through. From the graph, the forces (in grams) were determined to cut through at a distance of 25.4 millimeters, and 10 millimeters, and were normalized to validate the consistency of the blades. These normalized forces are hereinafter respectively referred to as NL1 (for the 25.4 mm distance) and NL2 (for the 10 mm distance).
- the blades were stainless steel cutter blades with a sharp edge of 70 mm, which were calibrated using a load of 4 N on a neoprene sheet of about (1.57 +/- 10%) mm and a hardness of (50 +/- 5) shore A. This was performed at the beginning and at the end of the test. A new blade was used for each measurement, i.e. each load.
- the sample was a rectangular piece of textile of 50x100 millimeters placed at a react of 45 degrees.
- the mandrel was a rounded electroconductive bar with a radius of 38 millimeters and the sample was mounted onto it using double-face tapes.
- the cutting edge was drawn across the textile on the mandrel at a right angle with the longitudinal axis of the mandrel. Cut through was recorded when the cutting edge makes electrical contact with the mandrel.
- the normalized forces were reported as the cut resistance forces, respectively NL1 and NL2 expressed in grams for a cut length of 25.4 mm and 10 mm.
- the test is conducted at (23 +/- 2) °C and (50 +/-5) % relative humidity.
- the 25.4 millimeters cut can be classified as a tear-like-cut and the 10 millimeters cut can be classified as a puncture-like-cut. These two belong to different regions of the cut-length - cut-force relationship, which is a non-linear curve. It was therefore convenient to define a combined index, which has the merit to compound the two behaviors. This index is hereafter referred to as the Combined Tear Puncture Cut Performance Index, CTPCPI. It was computed as per the following equation:
- CTPCPI 12 « ⁇ 25.4 10 mm
- This index was further normalized for a constant weight of fabric composition, hereafter selected at 800 grams per square meters. This mass per square area is a realistic value with regard to the protective clothing applications such as gloves for industrial usage.
- This combined normalized index is given in grams per millimeter of cut length. The higher this index is, the higher is the cut resistance of the sample. For each example, 12 samples were tested. The result is the average of the results of the 12 tests.
- the synthetic fiber staples were produced from short para-aramid fibers of 38 mm length as per the state of the art spinning process used for the production of para-aramid staple yarns.
- the para-aramid short fibers were obtained by cutting continuous filament para-aramid yarns made of 1000 filaments of 1.5 dpf (1.6dtex) each.
- the synthetic fiber staples were produced from short aliphatic polyamide nylon 66 fibers of 38 mm length as per the state of the art spinning process used for the production of aliphatic polyamide staple yarns.
- the aliphatic polyamide short fibers were obtained by cutting continuous filament yarns made filaments of 1.9 dtex each.
- Examples 1 and 2 are comparative Examples.
- Example 3 is an example according to the invention. In order for the results to be comparative, all three examples were realized for a relatively constant value of the total dtex (which is representative of the linear density of a fiber) and a relatively constant value of the mass per surface area.
- Example 1 (Comparative)
- the samples were cut to the adequate dimensions and shapes, circular for the abrasion testing and rectangular for the cut performance measurement, to perform 6 abrasion tests and 12 cut tests. Each sample had therefore a total dtex of 3570 (five times 714 dtex).
- the abrasion resistance measured was 900 cycles.
- the forces measured in the cut resistance test were 821 g for a cut length of 25.4 mm and 1666 g for a cut distance of 10 mm.
- the combined CTPCPI.N normalized index was given by the following calculation [(821/25.4 + 1666/10)/2]x800/800 and equaled 99 g/mm.
- the samples were cut to the adequate dimensions and shapes, circular for the abrasion testing and rectangular for the cut performance measurement, to perform 6 abrasion tests and 12 cut tests.
- the abrasion resistance measured was 3000 cycles.
- the forces measured in the cut resistance test were 759 g for a cut length of 25.4 mm and 923 g for a cut distance of 10 mm.
- the combined CTPCPI.N normalized index was given by the following calculation [(759/25.4 + 923/10)/2]x800/826 and equaled 59 g/mm.
- CTPCPI.N of example 2 reveals an approximate 40% inferior cut resistance compared to example 1. On the other side the abrasion resistance of example 2 is three times superior to the one of example 1.
- Example 3 Three independent non composite para-aramid strands A and four independent nylon strands B were fed to the same circular knitting machine as the one used in Example 1 without prior assembling of any sort. A sleeve of sufficient length was knitted to obtain a uniform and reproducible pattern of a mass per surface area close to 843 g/m 2 . The samples were cut to the adequate dimensions and shapes, circular for the abrasion testing and rectangular for the cut performance measurement, to perform 6 abrasion tests and 12 cut tests.
- Each sample had therefore a total dtex of 3622 (three times 714 dtex plus four times 370 dtex).
- Each sample comprised 50.1 % by weight, of non composite para-aramid strand relative to the weight of the sample, and 40.1 % by weight, of nylon strand, relative to the weight of the sample.
- the abrasion resistance measured was 6000 cycles.
- the forces measured in the cut resistance test were 1170 g for a cut length of 25.4 mm and 1400 g for a cut distance of 10 mm.
- the combined CTPCPI.N normalized index was given by the following calculation [(1170/25.4 + 1400/10)/2]x800/843 and equaled 88 g/mm.
- CTPCPI.N of Example 3 reveals an approximate equal cut resistance compared to Example 1.
- the abrasion resistance of Example 3 is six times superior to the one of Example 1 and surprisingly two times superior to the one of Example 2.
