Description

Cut-resistant protective composition containing high tenacity fibers and application thereof

The present invention relates to a textile yarn, in particular to a cut-resistant protective composite yarn containing high-strength fibers and its application in the fields of textile fabrics, clothing, shoes, protective gear, sporting goods and the like.

Over the years, in the textile market, functional textile fabrics have been continuously introduced to make clothing suitable for the climate, such as heat radiation resistance, UV resistance, moisture wicking, sweat wicking and quick drying, cooling or warmth. Textiles, etc., and even health-related textiles, such as far-infrared textiles and antibacterial textiles.

Further, the textile industry has developed cut-resistant textiles. Since the fibers in cut-resistant textiles are usually rigid materials with a certain strength, they can be made into clothing and worn on the human body and have a protective function, but they are not as good as ordinary natural fibers or chemical products. The fibers are soft and comfortable, and at the same time, the knitting machine is not easy to hook the rigid material yarn, so how to have cutting-resistant, soft and comfortable and easy to hook and knit textiles at the same time. the subject.

The main purpose of the present invention is to provide a cut-resistant protective composition containing high-strength fibers, which can be easily crocheted and woven by a knitting machine, so as to reduce the production cost.

The secondary objective of the present invention is to provide a cut-resistant protective composition containing high-strength fibers, which can be woven into textiles with different protective properties to meet the needs of the consumer market.

Another object of the present invention is to provide a cut-resistant protective composition containing high-strength fibers for weaving textiles with cut-resistant effect, softness and comfort, and easy hooking and weaving, and applied to the clothing market.

The reason is that, in order to achieve the aforementioned object, the present invention provides a cut-resistant protective composition containing high-strength fibers, which at least comprises a main yarn and a secondary yarn to form a composite yarn, and the main yarn is relatively High resistance or small coefficient of friction on the secondary yarn, the primary yarn and the secondary yarn are combined with each other in adjacent connection or winding connection to form the composite yarn, which can be easily hooked by the knitting machine Weaving and knitting textiles with different protective properties are used in clothing, shoes, protective gear, sporting goods, backpacks, handbags and/or luggage and other markets; further, the present invention further includes a hot melt adhesive yarn for combining The composite yarn is formed from the main yarn and the secondary yarn, so that the textile woven by the composite yarn has the effect of heating and fixing the shape.

Please refer to the first and second figures, the cut-resistant protective composition containing high-strength fibers disclosed in the present invention at least comprises a main yarn (22) and a secondary yarn (24) to form a composite yarn ( 12).

The primary yarn (22) is relatively high resistance such as high shear and/or high tension to the secondary yarn (24), the primary yarn (22) and the secondary yarn (24) are tied to each other The composite yarn (12) is formed by adjoining connection or winding connection, and is used to resist the cutting or cutting of a sharp object such as a knife; wherein, the main yarn (22) can be made of high-strength polyethylene (high-strength polyethylene). PE) fiber, Kevlar fiber, metal fiber such as stainless steel wire fiber or glass fiber, the secondary yarn (24) is a fiber whose friction coefficient is larger than that of the primary yarn (22) and can be set as natural Fibers, polyester fibers, nylon fibers or polypropylene fibers to be crocheted for weaving by a loom such as a weft knitting machine.

Please refer to the third figure, the present invention adopts the primary yarn (22) having a rigidity with a smaller coefficient of friction to combine the secondary yarn (24) having a flexibility with a larger coefficient of friction to form the composite yarn (12). ) to be hooked and woven into a textile fabric (14) such as a knitted fabric by a loom such as a knitting weft knitting machine; wherein, the textile fabric (14) is woven from a plurality of composite yarns (12) , one of the composite yarns (12) is woven in a similar sine wave shape, and the other composite yarn (12) is also woven in a sine wave shape and is serpentinely reciprocating through the composite yarn (12) A series of spaced crests are used to form a woven fabric (14) with a plurality of looped surfaces.

The textile fabric (14) adopts the cut-resistant protective composition containing high-strength fibers disclosed in the present invention and further utilizes different combinations and weaving processes of the primary yarn (22) and the secondary yarn (24), the textile fabric (14) Can resist a sharp object such as cutting, slashing or stabbing a knife, the textile fabric (14) can resist friction damage from sharp glass slag or metal slag, and the textile fabric (14) can resist human or animal teeth bite.

The textile fabric (14) adopts the cut-resistant protective composition containing high-strength fibers disclosed in the present invention, and the content of the composite yarn (12) can be 10% to 90%, and the effect of the present invention can also be achieved, It is in response to the needs of different functions.

Please refer to the fourth figure, the textile fabric (14) may further comprise a covering layer (16), the covering layer (16) is set as a smoothing agent for coating the textile fabric (14) with a looped surface , then the textile fabric (14) has a better effect against a sharp object; wherein, the smoothing agent can be an emulsion of dimethyl silicone oil and amino silicone oil or other compounds with smoothing effect.

The further application of the textile fabric (14) is to make a human-wearable garment, sleeve cover and/or protective gear to create a garment that is resistant to cuts, abrasions, snags, cuts and animal bites; in addition, the The textile fabric (14) can be applied to the sports goods market, such as skateboarding sportswear, hockey sportswear, skateboarding shoes and/or hockey sports shoes, etc., to prevent cuts during sports or competitions; the textile fabric (14) can also be applied In the market of backpacks, handbags and/or suitcases, it is used for protection and anti-pickpocketing.

Please refer to the fifth and sixth figures, the composite yarn (12) further comprises a hot melt adhesive yarn (26), the primary yarn (22), the secondary yarn (24) and the hot melt adhesive Yarns (26) are assembled in adjacent connection or winding connection to form the composite yarn (12), and the composite yarn (12) is heated to a suitable temperature for an appropriate time to return to room temperature , the hot-melt adhesive yarn (26) will be melted and used to firmly bond the primary yarn (22) and the secondary yarn (24). The invention utilizes the characteristics of hot melt adhesive, that is, the hot melt adhesive is solid at normal temperature, and when heated to a certain temperature, it melts into a fluid adhesive, and after being separated from the heating device, it is rapidly cooled and solidified, and the bonding speed is fast.
