Description

[Technical Field]

[0001] The present invention relates to the field of textiles for clothing, in particular textiles for protective clothing for motorcyclists. [Background technology]

[0002] As is known in the field of accident prevention, puncture-resistant, cut-resistant, highly abrasion-resistant and puncture-resistant fabrics are commonly used in the field of safety footwear and safety clothing (e.g., puncture-resistant insoles, bulletproof vests, motorcycle for clothing suit ) are particularly important and are suitable for protecting the user in case of an accident.

[0003] The EN 13595-1:2002 standard is the main European standard regulating protective clothing for professional motorcyclists. This standard provides for the division of clothing into four zones, with zones 1 and 2 corresponding to the most exposed and highest risk areas (elbows, arms, shoulders, knees, and buttocks), and zones 3 and 4 corresponding to lower risk areas. are. In addition, there are two safety levels There is , Level 1 covers the minimum requirements, with Level 2 being the highest requirements for higher performance materials, so-called "racing".

[0004] [Table 1]

[0005] Currently, protective clothing for professional (and non-professional) motorcyclists is made from leather. Not professional Used for motorcycle clothing, the actual cow leather is rider of suit (which has a lower quality compared to kangaroo, which is used forcibly in 2 Kangaroo leather (professional motorcycle leather) with a weight of 1.2-1.6 mm and abrasion resistance according to EN 13595 standard >4 seconds (level 1). suit(used for this purpose) is usually 800-1000gr / m 2 It has a weight of 0.8 to 1.2 mm, a thickness of 0.8 to 1.2 mm, and is abrasion resistant according to the EN 13595 standard >4 seconds (level 1). It should be noted that in all circuits for speed racing, leather is not permitted by the rules of the interior clothing. However, leather has the following drawbacks: it is not breathable, cannot be washed, and has no insulating properties (heat generated). This can cause the rider to suffer burns when falling. ), flammable, non-water repellent, compared to fabric not much Comfort in No, it's not eco-friendly.

[0006] [Table 2]

[0007] Research in this field is constantly aimed at providing fabrics that are as soft, elastic and breathable as possible in order to minimize undesirable effects when worn while ensuring the essential protective effect.

[0008] In accordance with the above-mentioned points, attempts have been made to increasingly reduce the weight and thickness of the fabrics used while maintaining the desired protective effect; one example is the motorcyclist fabric described in patent document 1, in the name of the same applicant, in which the diameter of the weft yarns constituting the weft is equal to or different from the diameter of the warp yarns, the count of the weft yarns being between 100 and 700 dtex, and which may be colored, coated or resinified. In particular, a fabric is described which consists of a weft yarn with a number of overlapping threads of 10 (corresponding to a weft yarn with a number of overlapping threads of 5) and a warp yarn with a number of overlapping threads of 20 (corresponding to a warp yarn with a number of overlapping threads of 10), in which the weft yarns have a count of 580 dtex (PL HT), High strength With polyester Elasticity and The warp yarn has a count of 240 to 280 dtex. High strength Polyester. Such fabrics have a density of about 1000 g / m 2and a thickness of approximately 1.8 mm. Such fabrics are certified to the current EN ISO 13595-2002 standard:- PROTECTIVE CLOTHING FOR PROFESSIONAL MOTORCYCLISTS, Class 2, but despite their weather resistance and comfort, the weight and thickness of the fabrics were limited compared to the leather garments currently in widespread use by professional motorcyclists.

[0009] The aforementioned standard specifies two security levels, Class 1 and Class 2; for Class 1, the abrasion value on the CAMBRIDGE ABRASION MACHINE (the equipment required by the standard to perform the abrasion resistance test) must exceed 4 seconds, and for Class 2, the value must exceed 7 seconds. This type of test result is very aggressive for the tested material, so the standard required To achieve the requirements, it was necessary to create materials of significant weight and thickness, resulting in heavy and very uncomfortable clothing. , own Two-wheeled vehicle and motorcycles During non-professional driving, Such It does not impose an obligation to wear protective clothing that complies with the standard. It is expected that the future EN 17092 standard will see three new levels of protection become less restrictive, allowing habitual motorcyclists to wear clothing that provides minimal protection in the event of an accident. Driver This is the reason why they are made to wear them.

[0010] The aforementioned The same applicant Patent documents include safety 、 Portability and comfort View ofWhile this was an important step forward from the point of view, the market requires increasingly lighter and thinner, but at the same time safe and resistant materials, in parallel with the new revision project of the EN ISO 13595 standard proposed to the European Commission. The new project of the standard proposed to the European Commission, pr EN 17092, establishes that the protection levels established by the standard itself will be 5, with the first two levels "A+A+A and A+A" being the most important, and the established requirements will remain the same as the two classes of protection of the current standard, called RACING requirements, while the urban motorcycle Three other levels of protection for the a These are called "ban requirements" and involve lower parameters than Racing, simply motorcycle To encourage habitual users to wear protective clothing. It is something to try. .

[0011] Our research then turned to structural and targeted improvements of the products produced to date, to provide suitable materials to the market and to comply with current and future European directives. [Prior art documents] [Patent documents]

[0054] Said adhesive means (also called glue) can be applied by blade, by point or by thermal transfer, and preferably, according to the present invention, the selected laminate is breathable, with airtightness and resistance to all environmental degradation to which the material is subjected (high temperature, low temperature, acidic sweat, alkaline sweat, water, etc.), without altering the adhesion between the layers to a minimum. elasticity It is a reactive polyurethane (PUR) by virtue of its ability to maintain exceptional softness.

[0055] Preferably, Point stacking By R Before proceeding to the final PUR phase, preferably 30-50g / m 2 In the amount of cloth and below cloth Both , spinning Yarn, warping and weaving process Applied in Ta All curing agents present on the fiber, as well as those present in the fiber or collected during previous operations Get Use good preparation to eliminate impurities.

[0056] Preferably, both the upper and lower fabrics are then purged in width to eliminate all impurities present in the fabric and to promote re-entry and fiber closure, preferably with the preferred presence of elastomer in both the weft and warp, which may be about 25% in both directions, the procedure being carried out at a temperature of about 90°C with the addition of water and possible detergent soap. After washing, the fabric is dried and preferably heat-set in a drying pass in a ramosa at a temperature of 165°C and a speed of 25 m / min, and then always in a ramosa heat-set at a temperature of 180°C and a speed of 25 m / min. Heat-setting is carried out throughout all subsequent procedures ( Lamination It helps to give permanent stability to the fabric (e.g. dyes, printing, finishing, industrial or domestic washing). After heat fixing, the fabric is steamed and rolled to make the surface uniform, restore softness to the fabric, and further uniformize the fabric by hardening and strain hardening through heat fixing.

[0057] If the upper and / or lower fabrics contain UHMWPE yarns (e.g., Dyneema®), the drying and heat-setting phase must be carried out in a tumbler, the industrial equivalent of a domestic dryer, which operates at temperatures below 100°C but performs the important mechanical action provided by the centrifugal basket, which determines the maximum re-penetration of the fibers, to obtain the same results in terms of the dimensional stability of the lamosa. Tumble drying is necessary for fabrics in which Dyneema® fibers (UHMWPE) are present, because above 110°C the fibers begin to soften, then melt, completely losing the characteristics that make them one of the most resistant fibers to abrasion, cuts, and tears commercially available. This operation in a tumbler is more expensive compared to heat-setting in lamosa. It takes time , because if not forced by technical reasons it is preferably avoided.

[0058] Once the two fabrics were prepared as described above, reactive polyurethane (PUR) Lamination Point twist We can move forward.

[0059] This procedure is preferably carried out at low temperatures on a machine where the thermoplastic PUR is melted from a pressure plate (an external attachment of the machine) heated to about 115°C and forced through a pump into a micro-perforated cylinder for application onto the fabric. Immediately after the adhesive is applied, a pressure of about 2.5 tons is applied and the roll is immediately wound up to form a large roll, which is then pressed between two rollers by a calender that remains stationary to allow crosslinking in a heated environment where the temperature must never drop below 15°C (the limit temperature at which the PUR crystallizes and becomes ineffective). Lamination The cutting time depends on the external temperature; at 20°C, a cutting time of 24 hours is sufficient (the minimum time below which it cannot be reduced), and below 20°C, the cutting time increases in proportion to the reduction in temperature itself.

[0060] This type LaminationThe advantage of is that once the section is complete, PUR will not revert any further, neither in high nor low temperatures, giving a permanent seal that will withstand all expected environmental aging and all household and industrial cleaning.

[0061] The present invention can be better understood in light of the following exemplary embodiments. [Example]

[0084] Lamination The upper fabric is purged widely, operated, and detergent soap is added at a temperature of 90°C to eliminate all impurities present in the fabric and to favor the re-entry and closure of the fibers, which in this case can be very high thanks to the favorable presence of about 25% elastomer in both the weft and the warp, and after washing it is dried at a temperature of 165°C, at a speed of 25 m / min, in a passage in a ramosa, then always heat-fixed at a temperature of 180°C, at a speed of 25 m / min, in a ramosa, and all subsequent steps ( Lamination , dyeing, printing, finishing, industrial or domestic cleaning, etc.) 、After heat setting, a rolling action is carried out with the application of steam to homogenize the surface and harden the fabric by heat setting. flexibility , hardening and distortion recovery.

[0085] The lower fabric is purged in width exactly as described above for the upper fabric, but the drying and heat-setting phase is carried out in a tumbler, the industrial equivalent of a domestic dryer, operating at temperatures below 100 ° C, but with an important mechanical action provided by the centrifugal basket, which determines the maximum re-penetration of the fibers, in order to obtain the same results in terms of the dimensional stability of the ramosa. The cloth When dyneema® fiber (UHMWPE) is present inside the fabric, Tumble dry need Let's say . because, When it exceeds 110℃, it becomes soft and begins to melt. , Ma Against wear, cuts and tears Most resistant One of the fibers In the market that This operation is more expensive than heat fixing in Ramosa. It takes time Therefore, it is preferable to avoid it if it is not required for technical reasons.

[0086] Two cloth Once prepared as above, 30-50g / m 2 Using an amount of PUR equal to R Reactive Polyurethane (PUR) Lamination can be progressed.

[0087] This operation is carried out on a cold machine where thermoplastic PUR is melted from a press plate (an external attachment to the machine) heated to about 115°C and forced by a pump into a micro-perforated cylinder for application onto the fabric. Immediately after application of the adhesive, two Lamination The fabric is then immediately wound up into a large roll, applying approximately 2.5 tons of pressure, which is then cooled to a temperature that never drops below 15°C. Teha (This invalidates the limit temperature that crystallizes PUR.) The crosslinking time depends on the external temperature (the minimum time that cannot be lowered) at 20°C for 24 hours. Below 20°C, the crosslinking time is of itself It increases in proportion to the decrease in temperature.

[0088] obtained Lamination The fabric is the same as the upper fabric in Example 4. Lamination In the case of 1000g / m 2 It weighs less than 1.5 mm and has a thickness of less than 1.5 mm and has demonstrated abrasion resistance according to the EN 13595 standard >16 seconds.

[0089] [Table 4]

[0090] The fabric is resilient, machine washable, breathable, fully recyclable, can be dyed and printed in any color, and can be made waterproof, windproof, fire resistant, etc.
