TABLE 1
In the invention, the tungsten wire with the diameter of 0.006-0.025mm is selected as the tungsten wire for forming the core yarn, and the tungsten wire has good performances of cutting resistance, high temperature resistance, electromagnetic shielding performance, flexibility, wearing comfort and the like.
The polyester yarn for forming the core yarn has the following characteristics: 1. the strength is high. The strength of the short fiber is 2.6-5.7cN/dtex, and the high-strength fiber of the terylene is 5.6-8.0 cN/dtex. Because of lower hygroscopicity, the wet strength and the dry strength of the nylon are basically the same, and the impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose fiber. 2. The elasticity is good. The elasticity is close to that of wool, and can be almost completely recovered when the wool is stretched by 5 to 6 percent. The wrinkle resistance is higher than other fibers, namely the fabric is not wrinkled, the dimensional stability is good, the shape retention is good, the elastic modulus is 22-141cN/dtex, and is 2-3 times higher than nylon. 3. Can be used at-70 ℃ to 170 ℃, and is the best in heat resistance and heat stability in synthetic fibers. 4. The surface of the terylene is smooth, and the internal molecules are arranged closely. 5. The wear resistance is good. The wear resistance is second to the best wear resistance chinlon, and is better than other natural fibers and synthetic fibers. 6. The water absorption is low. The terylene has low water absorption and moisture regain and good insulating property, but the terylene has excellent setting property due to low water absorption, and the terylene yarn or fabric can be used for a long time after being washed for many times. In conclusion, the terylene has the characteristics of firmness, durability, good elasticity, difficult deformation, stiffness, easy washing, quick drying and the like.
The density of the spandex filament forming the core yarn is 1-1.25g/cm3It has great elasticity, and has elongation of over 400% and even up to 800% and resilience of 95-99% when stretched 500%. Generally, the greater the relative molecular mass of the soft segment portion in the molecular structure of the spandex filament, the higher the elasticity and rebound resilience of the fiber. The breaking strength of the spandex filament is 0.35-1.05cN/dtex, the spandex has small elastic modulus and good softness, the heat resistance of different varieties of spandex with different differences is large due to different proportions of components and soft and hard chain segments, and most fibers are stored for a short time at 95-150 ℃ without damage; the moisture absorption rate of spandex is generally 0.3% -1.3%; the durability of the spandex is strong, namely the fatigue resistance is good, and in the extension range of 50% -300%, a stretching and shrinking fatigue test is carried out for 220 times per minute, the spandex can resist 100 ten thousand times without breaking, and the rubber filament only can resist 2.4 ten thousand times; spandex is resistant to most acids, bases, and chemical solvents.
Because polyester spandex has lower elasticity and rebound ratio than polyether spandex, polyester spandex is decomposed in thermokalite, and bleaching agents such as sodium hypochlorite can turn the fiber yellow and reduce the strength, the spandex composition preferably contains 85% or more of polyurethane and the elastic modulus of polyether spandex is O.11cN/dtex.
The polyamide fiber is selected as the polyamide fiber which is the fiber with the best wear resistance in all textile fibers, and the wear resistance of the polyamide fiber is 10 times that of cotton, 20 times that of wool and 50 times that of viscose. The density of the polyamide fibers was 1.14g/cm3And, of all fibers, only higher than polypropylene and polyethylene fibers. Although polyamide fibers are less dyeable than natural and man-made fibers, they are easier to dye among synthetic fibers and are generally dyed with acid dyes, disperse dyes, and other dyes.
Further, the polyamide fiber is selected from one or a mixture of polyamide 6 fiber and polyamide 66 fiber. The polyamide 6 fiber and the polyamide 66 fiber have excellent performances of high strength, good rebound resilience, wear resistance, fatigue resistance and the like, and the difference between the excellent performances is that the melting point and the softening point are different, the polyamide 6 fiber is respectively at 220 ℃ and 180 ℃, and the polyamide 66 fiber is respectively at 260 ℃ and 220 ℃. Since the cost of the polyamide 6 fiber is lower than that of the polyamide 66 fiber, and the hygroscopicity of the polyamide 6 fiber is slightly higher than that of the polyamide 66 fiber due to the existence of monomers and low molecular substances, the moisture regain of the polyamide 6 fiber is 3.5% -5.0%, and the moisture regain of the polyamide 66 fiber is 3.4% -3.8% under a standard state. Therefore, polyamide 6 fiber can be preferably selected as the nylon yarn. When the polyamide yarn is a mixture of polyamide 6 fiber and polyamide 66 fiber, the following requirements are met: the weight ratio of the polyamide 6 fiber to the polyamide 66 fiber is 3-10:2, so that the performances of high strength, good rebound resilience, strong wear resistance and the like can be realized, and the reduction of the production cost can be ensured.
The ultra-high molecular weight polyethylene fiber forming the wrapping yarn adopts high-strength high-modulus polyethylene fiber with the linear density of 80-400D and the molecular weight of 100-500 ten thousand, and has the performances of high specific strength, high specific modulus, wear resistance, impact resistance, cutting resistance and the like, wherein the specific strength is more than ten times of that of steel wires with the same section, the specific modulus is only inferior to that of special-grade carbon fiber, and the requirement of the strength and elongation test on the performance of a strength instrument is much higher than that of common fiber.
In the spinning process, the draw ratio of spandex filaments, namely the pre-drafting multiple, affects the elasticity of the covered yarn and fabric, and also affects the strength elongation, yarn evenness and creep property of the covered yarn. The pre-drafting multiple of spandex is too small, so that the advantage of good elasticity of the elastic fabric can not be fully exerted, spinning is difficult when the drafting is too high, yarn breakage is easy to cause, and the product quality is reduced along with the yarn breakage.
In addition, the percentage content of the spandex yarn also affects the elasticity of the covered yarn, and the covered yarn is high in content and good in elasticity. Under the condition of certain spandex filament specification, the drafting multiple is increased, the percentage content of spandex filaments is reduced, namely the pre-drafting multiple of spandex is in inverse proportion to the percentage content of finished spandex.
The twist of the covered yarn affects the quality, the tenacity and the evenness of the yarn. The twist is increased, so that the cohesive force between the outer-coated fiber and the spandex silk can be increased, and the strength of the coated yarn is improved. The twist is too low, the wrapping fiber is loose, the wrapping effect is influenced, and the core exposure phenomenon occurs, so the twist is higher during mechanical wrapping. However, the twist is too high, the fabric feels hard, and the drapability is poor. Generally, the twist degree varies with the denier of the yarn and the style requirement of the fabric is different, for example, the twist degree of an N40D +20D bag is about 600, and the twist degree of an N70D +40D or T150D +40D bag is controlled to about 480. The elongation of the yarn is mainly determined by the performance of the spandex core yarn, the twist is too large, the outer layer fiber is covered too tightly, the elastic effect of the spandex yarn cannot be fully exerted, and the elongation is reduced. As twist increases, evenness of the yarn improves. The twist is too small, the covering fiber is loose, and the fiber moves slightly along the axial direction of the yarn due to friction and the like in the spinning process, so the yarn evenness is deteriorated. Poor yarn evenness and reduced yarn strength affect fabric strength, and uneven yarn weaving can cause various defects and yarn streaks on the fabric and affect appearance quality.
As can be seen from example 1 and table 1, in examples 1 to 7, the tungsten filament blended and cut yarn was obtained by using spandex filament and polyester double-covered tungsten filament yarn as core yarn, then covering the core yarn with nylon filament, and finally covering the core yarn with ultra-high molecular weight polyethylene fiber. Because the tungsten filament forming the core yarn has good performances of cutting resistance, high temperature resistance, electromagnetic shielding performance, flexibility, wearing comfort and the like, the spandex filament forming the core yarn has high elasticity, the elongation at break of the spandex filament is as high as 400-800 percent, the high recovery performance is realized, the elongation recovery rate is more than 90 percent, the polyester filament forming the core yarn has the characteristics of high strength, good elasticity, good wear resistance, low water absorption and the like, and the nylon filament forming the covering yarn has excellent performances of wear resistance, moisture absorption, elasticity, strength and the like, the ultrahigh molecular weight polyethylene fiber forming the covering yarn adopts high-strength high-modulus polyethylene fiber with the linear density of 80-400D and the molecular weight of 100-500 ten thousand, and has the performances of high specific strength, high specific modulus, wear resistance, impact resistance, cutting resistance and the like, so that gloves or other spinning products (such as shoes and caps, shoes and other spinning products) woven by adopting the, Clothing and other products) has excellent water resistance, bending resistance, cutting resistance, flexibility, washing deformation resistance and other performances, improves the wearing comfort, and can reach European Union EN388 standard wear resistance level 4, cutting resistance level 5, tear resistance level 4 and puncture resistance level 4.
The yarns can be used for weaving other textile products except gloves, such as clothes, shoes, hats and other products, and the textile products also have the excellent performances, so that the wearing comfort is improved. The invention does not adopt glass fiber materials to prepare yarns and textiles, thereby reducing the pollution to the environment and being green and environment-friendly.
As can be seen from table 1, the glove blanks woven by using the tungsten filament blended cutting-resistant yarn of example 6 are better in abrasion resistance, tear resistance, cut resistance, puncture resistance, and the like than those woven by using the tungsten filament blended cutting-resistant yarns of other examples, and may be caused by using the tungsten filaments having a large diameter and a high content, the polyester filaments having a large fineness and a high content, the spandex and the polyamide filaments having a large fineness and a high content, the ultra-high molecular weight polyethylene fibers having a large fineness and a high content, and the reasonable twist of each covered yarn.
