Description

High-strength, cut-resistant core yarn

The invention relates to a high-strength and cut-resistant core-spun yarn, which is a core-spun yarn structure with cutting resistance and puncture resistance, and can be made into a puncture-proof, wear-resistant and cut-resistant multifunctional structure by using the core-spun yarn structure. Fabric player.

[Please refer to the first figure] According to the conventional core-spun yarn, most of the inside is only filled with the axis of a single steel wire or glass fiber material, and the axis of the steel wire or glass fiber material can make the core yarn puncture resistant. The effect of cutting resistance, however, in the process of processing into yarn, the tensile strength of the steel wire or glass fiber axis is relatively low, and it is prone to breakage, so there may be production interruption during the process of making the yarn. In the case of poor production efficiency and the smooth surface of the core wire, the fiber line coated on the outer layer of the axis is easily detached, thereby affecting the practicability of the structure, and there is considerable room for improvement.

In view of the above-mentioned shortcomings, the inventor believes that it has the urgent need to make corrections, and that it has been engaged in the design and manufacture of related products for many years, and has always adhered to the excellent design concept, and researched and created the above disadvantages. After continuous efforts, the high strength and cut-resistant core yarn of the present invention was finally introduced, which improved the product's efficacy by correcting the excellent product structure.

The main object of the present invention is a high-strength and cut-resistant core-spun yarn, which is a core-spun yarn structure which is improved in the production speed of the conventional core-spun yarn, is relatively easy to be interrupted, and the outer fiber strand is relatively easy to be separated from the axis.

For the purpose of the foregoing disclosure, the present invention is a high-strength and cut-resistant core-spun yarn, which mainly comprises a core portion and a wrap portion, and the core portion is mainly composed of two different materials of a first core wire and a second core wire. The core body is composed of a wire made of stainless steel filament material, and the second core wire is a wire made of a para-aramid material, and is in the first core wire and The outer periphery of the second core wire is tightly wrapped with a wrap portion, and the wrap portion is composed of a large number of short fibers wrapped around the outer periphery of the first core wire and the second core wire, and the short fiber is a para-aramid material. The fiber surface picked up by the surface layer of the second core of the core has a better coefficient of friction, so that the first core wire and the second core wire are closely attached to each other during the process of forming the yarn, thereby increasing the tensile strength. The strength is not easy to break, and the effect of improving production efficiency and quality is improved, and the preferred coefficient of friction of the second core wire allows the covering portion to be tightly wrapped around the periphery of the first core wire and the second core wire, which is less likely to cause separation, and can improve the rear section. When used, the cladding will be aligned with the shaft The problem of detachment, and the second core of the core and the short fibers of the entangled portion also have high strength and toughness and good mechanical strength, so the core yarn structure has extremely high cutting resistance and tensile strength, further The finished product made of the core-spun yarn structure can obtain the effects of stab resistance, abrasion resistance and cutting resistance, and then becomes a product which is quite in line with its progress.

The invention relates to a high-strength and cut-resistant core-spun yarn, [refer to the second and third figures] mainly comprising: a core portion (1), mainly composed of a first core wire (11) and a second core wire (12) A core body made of different materials, the first core wire (11) is a wire made of steel wire or glass fiber material, the steel wire can be stainless steel filament, and the second core wire (12) is a para-aromatic a wire made of a polyamide material, the second core wire (12) having a rougher burr surface, and a wrap portion is tightly wrapped around the periphery of the first core wire (11) and the second core wire (12) ( 2), the first core wire (11) and the second core wire (12) are fitted together in the wrap portion (2); the wrap portion (2) is wrapped around the core portion ( 1) an outer fibrous body, and the wrap portion (2) is composed of a large number of short fibers (21) wound around the outer periphery of the first core wire (11) and the second core wire (12), and the short fiber (21) is Made of para-aromatic polyamine materials.

The manufacturing process of the high-strength and cut-resistant core-spun yarn of the invention (see the fourth figure) is to use the friction coating principle of the short-spinning machine (21) to wrap the short fiber around the first core wire ( 11) and the periphery of the second core wire (12), the first core wire (11) and the second core wire (12) are filled in the wrap portion (2) to form a core yarn structure, due to the second core wire Both (12) and short fibers (21) are high-strength and tough materials, so the core-spun yarn structure has extremely high cutting resistance and tensile strength, resulting in better strength, toughness, cut resistance and other additions. Characteristics, so in the process of making the yarn, the second core wire (12) is less likely to be broken, which has the effect of improving production efficiency and quality, and the second core wire (12) has a rough rough surface and a high friction coefficient. The phenomenon that the covering portion (2) is entangled on the periphery of the first core wire (11) and the second core wire (12) is less likely to be separated.

The high-strength and cut-resistant core-spun yarn of the invention has the advantages that the second core of the shaft core has a better friction coefficient due to the surface of the fiber picked up by the surface layer, so that the first core wire and the process of forming the yarn The second core wires are closely attached to each other, thereby increasing the tensile strength and not easily breaking, and effectively improving the production efficiency and quality, and the preferred coefficient of friction of the second core wire allows the covering portion to be tightly entangled in the first core wire and the second core wire. The outer periphery is less prone to separation, and the second core of the core and the short fibers of the entangled portion also have high strength and toughness and good mechanical strength, so the core yarn structure has extremely high cutting resistance and tensile strength. Sexually, the finished product made of the core-spun yarn structure can obtain the effects of stab resistance, abrasion resistance and cutting resistance, and then become a product which is quite in line with its progress.

In summary, it is understood that the present invention is novel, and the present invention is not found in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is, the equivalent changes and modifications made by the invention in accordance with the scope of the invention are still within the scope of the invention.
