[0001] BOOTS AND PRODUCTION METHOD WITH TWO DIFFERENT LAYERS AND TWO DIFFERENT MATERIAL INTERIOR LINING
[0002] Technical Field
[0003] The invention is designed to ensure the work safety of employees, to protect their health and to ensure the safety of the user. Equipped with breathable and light weight inner lining fabric to increase comfort, protects the user from cold in difficult weather conditions, prevents sweating and insulates occupational and safety boots with enhanced features and the production of the boots method is concerned.
[0004] Previous Background
[0005] Recently, in order to increase the effectiveness of boots used for work safety completely rubber, all polyvinyl chloride (PVC), completely polyurethane (PU), instead of completely ethylene vinyl acetate (EVA) or polyurethane boots, small some features such as comfort, insulation and other wear by making modifications development studies are being conducted.
[0006] For example, rubber sole and EVA upper or TPU sole or rubber and upper Thermally insulating boots made of thermoplastic polyurethane blend (PU / TPU) is used. Being equipment utilised by the users for a full work day, ergonomic structure and practicality of use are very important for occupational and safety boots. Therefore, removable pile socks with good thermal isolation properties are added into the boots developed to provide comfort and adapt to harsh weather conditions. Due to their lack of practicality in use, pile socks are not generally preferred by users. For this reason, later these pile socks were glued to the foot wear and started to be used. In addition, they are completely rubber. The heavy of safety boots makes the users very tired. Due to the reasons detailed above, structural properties of occupational and safety boots in the current state or the art are found lacking. Thus, due to user complaints, the need arises to use lighter materials at upper parts of the boots with heavy construction and studies to develop the structural properties of boots continue.
[0007] Cold insulation measurements in work safety boots are measured from the sole of the boots used as a standard and compliance with the specifications is determined by this test method. It is determined according to the EN ISO 20347 and EN ISO 20345 standards.
[0008] Cold and heat insulation spectra and measurements to determine these spectra values It is made only from the sole part of the footwear.
[0009] Today, the required conditions of these specifications are met by increasing the sole thickness of work safety boots. However, in reality the users prefer boots which have thick upper parts and good heat isolation as well as thick soles in order to avoid feeling cold in harsh weather conditions. However, boots which have both thick soles and thick upper sections are very heavy and thus are not very practical to use. In addition, lacking breathability, these boots also make user's feet sweat. Occupational and safety equipment with the above mentioned features used in the present technique in his boots;
[0010] The user's feet get cold due to the insufficient heat insulation of the boot,
[0011] Because the boots are heavy, they tire the user.
[0012] Sweating due to lack of air circulation inside the boots doing, and the feet getting cold after sweating,
[0013] Due to the impracticality of using boots, users are not satisfied performance cannot be obtained,
[0014] In the current technique, pile socks are used to increase the thermal insulation of the upper parts of the foot. In addition to use of pile socks, an alternative design referred to as rigger boot in the literature has mouflon lining sewn or adhered into the boots for heat isolation in the current state of the art. Later addition of lining by sewing or adhesives onto the previously completed boots can cause problems in use. In addition, post-production sewing or adhesive interventions can also cause wastage of inner isolation material and increases in boot costs due to potential production errors.
[0015] Purpose of the Invention
[0016] The main purpose of the invention is to improve ergonomics, heat insulation, ergonomic and practical to develop usable work and safety boots.
[0017] Another purpose of the invention is to improve the production process of the said work and safety boots is to facilitate.
[0018] Another purpose of the invention is to produce with lighter materials than existing techniques. Maximum efficiency is achieved with occupacinal and safety boots that do not tire the user is to do.
[0019] Another purpose of the invention is to reduce production costs by reducing production waste, is to be lowered.
[0020] Like this;
[0021] Thanks to the improved thermal insulation of the boot, the user's feet do not get cold is provided,
[0022] Reduced production waste due to the ease of production of the boot,
[0023] Due to the low hardness of the insulation material in the insole increased comfort,
[0024] Thanks to the fact that the boots are made of light materials, it does not tire the user.
[0025] Thanks to the air circulation inside the boot, sweating is prevented. The boots are easy to use and practical, providing maximum benefit from the users efficiency is achieved.

[0045] The invention has improved heat insulation properties and prevents foot sweating, which is a occupational and safety product it is about boots and the production method of these boots.
[0046] Occupational and safety boots have an from the inside to the outside, mesh layer (1), inner sock (2), a lining sock (3) and a PU outer layer (4) it consists of.
[0047] Air mesh layer (1) to provide air flow and increase breathability it is a special fabric layer designed for this purpose. This layer has a porous structure that allows air to circulate freely between two fabric surfaces. The Air mesh layer (1) has lightweight, durable and flexible properties, it provides comfort to the user by reducing sweating.
[0048] The inner sock (2) consists of two parts. These parts respectively, the inner sock sole (2.1) and the inner sock toe (2.2) that covers the ankle and calf parts of the user's foot. The inner sock sole (2.1) is PU sponge made of material. PU sponge, thanks to its flexible and soft structure, provides extra cushioning to the sole. This cushioning prevents impact during walking. It contributes positively to foot health by increasing absorption and provides the user with a comfortable it offers experience. Polyurethane sponge is long-lasting with its dense and durable structure.
[0049] It does not lose its shape or collapse despite being exposed to constant pressure. also ensures that the insole can be used for a long time. PU sponge is a lightweight material it offers comfort without increasing the weight of the boot. Lightweight boots are designed for the user It is less tiring for the user and provides ease of movement. PU sponge has an open cell structure which enables air circulation. Breathability, moisture and sweat on the feet It prevents the formation of bad odor by reducing the accumulation and protects foot health. PU sponge can take shape by adapting to the foot anatomy. Thus, it supports the sole of the foot, supports the foot to stay in the correct position and reduces fatigue.
[0050] PU sponge provides thermal insulation and helps keep feet warm in cold weather.
[0051] Inner sock cuff (2.2) is made of neoprene material. CR composition of neoprene % it can be from 15 to 100%. The components other than the CR. part can be made of EPDM, NBR etc. It can be made of different rubbers. Polyester based with waterproof and tear-proof properties it is covered with fabric. Since neoprene is a water-resistant material, it provides waterproofnesssafety boots when used as an inner sock.
[0052] This feature, keep feet dry, especially in humid or water-contact work environments. Neoprene provides good thermal insulation keeps warm in cold weather conditions. When used as an inner socks in boots,
[0053] It allows workers in environments to maintain body heat and work more comfortably. Since neoprene is a material with shock absorbing properties, it cushions sudden impacts or shocks that may occur to the feet. This contributes to the protection of the ankles and legs and increases comfort during long-term standing work.
[0054] Neoprene provides freedom of movement to the user thanks to its elastic structure. When used as an inner sleeve, it allows the foot and ankle to move comfortably, it is especially useful in jobs that require a lot of movement. Neoprene is used in many It is resistant to chemicals, oil and ozone. This feature is resistant to chemicals prevents damage to the inner layer of boots in work areas and extends its life. In the alternative embodiment of the invention, the inner sock cuff (2.2) is made of neoprene layer and PU sponge layer laminated. In optimum application, it is obtained by laminating both layers together with a thickness of 2 - 3 mm.
[0055] Lining socks (3) are made of polyester fabric to cover the user's foot up to the ankle. It does not wrap around the user's calf and thus when viewed from the outside of the boot, it is not visible as it remains under the outer layer (4). The inner surface of the sock (3) is smooth. There are holes (3.1) on the lining sock (3). Holes (3.1) are formed as detailed later in the specification.
[0056] It ensures that the lining sock (3) and the inner sock (2) stick together during the PU injection step. In the alternative application of the invention, the lining sock (3) the sparse stitching (3.2) line located on the lining sock (3) instead of the holes (3.1) is also can be used.
[0057] Polyester based TPU as lining sock (3) in an alternative embodiment of the invention is to use a tubular sock sewn from a film. This TPU film is optional it can also cover the entire boot. The aim is to ensure good progress of the injected PU and to increase the thermal resistance with an additional layer.
[0058] PU outer layer (4) completely covers the foot and ankle parts of the boot is a partially enveloping PU layer. PU material has high durability, increases the resistance of the boot against abrasion, tearing and cracking. Hard and tough in working conditions, for example on construction sites or in industrial plants, ensures long life of the boots. PU material is waterproof and therefore prevents water, mud and other liquids from seeping into the boot. This feature is especially Keeping feet dry provides comfort for those working in damp and wet environments and protection. PU material boots are recommended when working in oily areas and surfaces. The life of PU boots used in oily areas is much longer than other boots. PU is a very lightweight material as well as being durable. Using PU instead of heavy materials in boots reduces fatigue and provides comfort for workers who stand for long periods or move a lot. PU offers thermal insulation properties, which protects the feet in both hot and cold weather and prevents them from being affected by temperature changes. This feature allows work boots to be used comfortably in various weather conditions.
[0059] The flexible structure of the PU material has the ability to absorb impacts and shocks on the feet. This feature is especially useful against falling objects or high risk of impact.
[0060] It contributes to the protection of the feet in work environments.
[0061] The production stages of the mentioned boot are as follows.
[0062] Inserting the inner sock (2) into the core (6).
[0063] The inner sock (2) is an insulating layer made of neoprene and PU sponge. In this way, it differs from similar neoprene socks. The inner sock (2) is placed on the inside of the boot. Air mesh (1) layer that prevents sweating in the part that comes into contact with the foot it is covered with. The outer part is covered with polyester-based fabric that is waterproof and tear-proof. When sewn as a sock, the sole part is PU sponge and the upper part is neoprene.
[0064] Putting the lining sock (3) on the inner sock (2).
[0065] The liner sock (3) will not completely cover the entire inner sock (2). The liner sock will cover it up to a certain part (ankle level) that will not be visible from the outer surface of the finished boot.
[0066] By injecting PU material, the lining sock (3) and the inner sock (2) are bonded to each other bonding and simultaneous formation of the PU layer (4).
[0067] In the first step, the covers of the core (6) are closed and the PU is injected into the mold. While the PU injection covers the inner sock (2), it also leaks through the stitching gaps or holes (3.2) (3.1) and allows the inner sock and the liner sock to be connected to each other. The PU material completely covers the liner sock (3) and forms the outer layer (4). The smooth inner surface of the liner sock (3) allows the PU injection to progress easily within the mold.
[0068] At the same time, the PU material is only used for holes (3.1), seam gaps (3.2) and Thanks to the air diffused around them, an air gap, an air layer, is also provided between the lining sock (3) and the inner sock (2). The air gap, which provides great benefits for air circulation, keeps the user's feet warm and insulated without allowing them to sweat.
