Description

TECHNICAL FIELD

[0001] The present application relates to the field of ski wear fabric manufacturing technology, in particular to a ski wear fabric with waterproof, wear-resistant, breathable, warm and tear-resistant properties. BACKGROUND

[0002] Skiing is a favorite outdoor activity for many friends in winter, and the first thing to do is to choose a suitable set of clothes. Ski wear, as the name implies, is a garment worn while skiing. The main function of ski wear is waterproof, windproof, breathable, and the color is generally bright.

[0003] When skiing, most of the time is spent with ice and snow. In the process of skiing, snow will definitely stick to the clothes, and the snow left on the clothes will melt quickly. If the waterproofness of the ski report is not good, the snow water may seep into the clothes, making the skier uncomfortable or causing illness. In addition, the snow field is generally windy and cold, and the ski wear needs to be warm and windproof. The windproof function of ski wear is an important indicator of its warmth. When you slide down the slope at high speed, the cold wind whistles past your ear, and you will understand why the windproof function is so important to a ski wear. Skiing is a relatively intense sport, and a lot of heat is consumed during the exercise, and the amount of sweat also increases. If the sweat cannot be discharged in time, the underwear will be soaked, and it is not good to sweat in cold weather. Especially when the skier sits in the car or is relatively still, the sweat will condense in the clothes, and the condensation will quickly freeze into ice. At this time, if you continue to remain still, there is a risk of frostbite.

[0004] Currently, ski wear mainly uses different functional fabrics to achieve the above-mentioned waterproof, windproof, warm, wear-resistant and tear-resistant effects when making clothes. This will make clothing manufacturers find different raw material manufacturers, consume time and labor, and increase the inventory pressure of the fabric.

[0005] In summary, the market urgently needs a ski wear fabric with multiple functions to reduce the labor cost of clothing manufacturers searching for different fabrics and the inventory pressure brought by purchasing different fabrics. SUMMARY

[0006] The purpose of the present application is to provide a ski wear fabric with waterproof, wear-resistant, breathable, warm and tear-resistant properties.

[0007] The technical scheme adopted by the present application is as follows: a ski wear fabric, comprising a fabric main body, the fabric main body comprising a waterproof wear-resistant layer, a bacteriostatic heating layer and a far infrared layer; the waterproof wear-resistant layer is provided with a waterproof layer at the top end and the bacteriostatic heating layer at the bottom end; the bacteriostatic heating layer is provided with the far infrared layer at the bottom end; the fabric main body is a weft double weave structure, which is vertically interwoven by warp yarns and surface weft and inner weft; the warp yarns are composed of first warp yarns, second warp yarns and third warp yarns; the first warp yarns are blended yarns composed of silver chelated chitosan fibers and honeycomb polyester fibers, the second warp yarns are moisture-absorbing and heating acrylic fiber (Yirebao fiber of Shanghai Zhengjia Milksilk Technology Co., Ltd.) yarns, and the third warp yarns are modified Sorona filaments; the second warp yarns are spirally and tightly wound on the outer wall of the third warp yarns, and the first warp yarns are spirally and tightly wound on the outer wall of the second warp yarns; the surface weft is a flat-section colored polypropylene filament; the inner weft is a cross-section far infrared polyester DTY; the waterproof layer is a polytetrafluoroethylene film with one-way water-repellent property; the fabric main body is prepared by a finishing process including pre-shrinking, pre-setting, weight reduction, low-temperature setting, calendering and high-temperature setting; and the fabric main body is compounded with the waterproof layer by a film laminating machine after the finishing process.

[0008] The fabric utilizes the performance of the three-layer structure of the weft double weave, adopts functional warp yarns and weft yarns, so that the fabric main body has multiple functions and overcomes the single-function defect of traditional ski wear fabric; the waterproof wear-resistant layer makes the fabric waterproof and wear-resistant, ensuring the waterproof performance of the ski wear; the bacteriostatic heating layer can fully absorb steam and sweat during exercise, not only generates heat to meet the body temperature requirement, but also overcomes the stuffy feeling and bacterial breeding caused by sweating; the far infrared layer cooperates with the bacteriostatic heating layer to continuously supply heat energy, and the far infrared layer is in close contact with the human body, which can promote blood circulation and ensure sufficient kinetic energy of the human body during skiing. The bacteriostatic heating layer is mainly composed of warp yarns, which contain not only moisture-absorbing and heating acrylic fiber (Yirebao) with a moisture regain of 20%, but also silver chelated chitosan fibers. The two high-hygroscopic fibers make the bacteriostatic heating layer and the far infrared layer have a moisture absorption power difference, ensuring that water and water vapor quickly enter the bacteriostatic heating layer; the honeycomb polyester fibers in the layer can fully store heat, ensuring that the human body can supplement heat energy.

[0009] Further, the surface weave of the weft double weave structure is 1 / 3 twill, the inner weave is 3 / 1 twill, and the arrangement ratio of the surface weft and the inner weft is 1:1.

[0010] Further, the first warp yarns contain 2% of silver chelated chitosan fibers by weight, and the silver content in the silver chelated chitosan fibers is 170 ppm.

[0011] Further, the third warp yarn is made of modified Sorona filament DTY, which is produced by using glycerol and glucose as raw materials and bio-based enzyme as catalyst to produce 1, 3 propylene glycol, then adding fluorinated propylene amide into the 1, 3 propylene glycol and using ultrasonic oscillation and ultraviolet irradiation to produce 2, 2-difluoro-1, 3-propylene glycol, and then adding purified terephthalic acid into the 2, 2-difluoro-1, 3-propylene glycol to form Sorona filament containing fluorine element after copolymerization spinning, which has good water resistance and resilience.

[0012] The third warp yarn is made of modified Sorona filament, which not only gives the fabric good resilience, but also has water resistance inside the warp yarn, preventing the water absorbed by the antibacterial heating layer from accumulating inside the yarn, causing the strength of the yarn to decrease, and at the same time causing the water to be unable to be converted into kinetic energy for heating in time.

[0013] Further, the finishing process is specifically as follows:

[0014] 1) Pre-shrinking: refining and pre-shrinking the gray cloth in the liquid dyeing cylinder, adding refining agent GNB: 2-4 g / L, oil removal agent YS-101: 6-7 g / L, liquid alkali 1-1.5 g / L, heating to 80℃ at a heating rate of 1℃ / min, then heating to 120℃ at a heating rate of 1.5℃ / min, keeping for 40 min, and finally cooling to 80℃ at a cooling rate of 1℃ / min and taking out of the cylinder.

[0015] 2) Pre-setting: pre-setting the fabric after pre-shrinking in a setting machine at a temperature of 120℃, controlling the width of the fabric after pre-setting to be 3-5 cm wider than the finished product, to ensure that the fabric surface is fluffy and soft under the premise of being flat;

[0016] 3) Weight reduction: the fabric after pre-setting is subjected to weight reduction treatment, adding NaOH with a concentration of 30%: 3-5 g / L, refining agent GNB: 4-6 g / L, and treatment liquid with a bath ratio of 1:20 in the dyeing cylinder, first heating the treatment liquid in the dyeing cylinder to 95℃ at a rate of 1.5℃ / min, keeping for 30 min, then cooling to 60℃ at a rate of 1℃ / min, washing for 20 min, and finally cooling to 40℃ at a rate of 2℃ / min and taking out of the cylinder;

[0017] 4) Low-temperature setting: the fabric after weight reduction enters the setting machine and is treated at a temperature of 140℃ for 10-15 s, to ensure the fluffiness and flatness of the fabric;

[0018] 5) Calendering: the fabric after low-temperature setting is subjected to calendering treatment on the upper surface of the water-resistant wear-resistant layer by using a calendering machine, to ensure the tight windproof performance of the fabric; the calendering process is as follows: process temperature 160℃, calendering pressure 6 kg, and calendering machine speed 70 m / min.

[0019] 6) high temperature setting: after the calendering, the fabric is treated in the setting machine at the temperature of 180 DEG C for 5-8s, and in the process, the width direction is kept relaxed, so that the width direction is further reduced, and the fabric is more compact.

[0020] Compared with the prior art, the ski suit fabric has the following advantages:

[0021] (1) the fabric utilizes the performance of the three-layer structure of the weft double weave, adopts the combination of functional warp and weft, so that the main body of the fabric has multiple functions, and the single function of the traditional ski suit fabric is overcome; the waterproof and wear-resistant layer makes the fabric waterproof and wear-resistant, and ensures the waterproof performance of the ski suit; the antibacterial and heating layer can fully absorb the steam and sweat during exercise, not only generates heat to meet the needs of human body temperature, but also overcomes the stuffy feeling and bacterial breeding caused by sweating; the far infrared layer cooperates with the antibacterial and heating layer to make the main body of the fabric generate heat continuously, and at the same time, the far infrared layer is in close contact with the human body, which can promote blood circulation of the human body and ensure the kinetic energy of the human body during skiing.

[0022] (2) the antibacterial and heating layer is mainly composed of warp, and the warp contains not only moisture regain of 20% moisture-absorbing and heating acrylic (easy heat treasure), but also silver-chelated chitosan fiber, the two high-hygroscopic fibers make the antibacterial and heating layer and the far infrared layer have a power difference, so as to ensure that the moisture and water vapor enter the antibacterial and heating layer quickly; the honeycomb-shaped polyester fiber of the layer can fully store heat, and ensure that the human body can obtain heat energy supplement.

[0023] (3) the waterproof layer adopts polytetrafluoroethylene film with one-way water-repellent performance, which ensures that the fabric is breathable and has good waterproof effect.

[0024] (4) the main body of the fabric adopts multiple fiber components, and complex printing and dyeing finishing will damage the performance of the fibers; the colored polypropylene filament is used as the surface weft, which reduces the dyeing process in the treatment process.

[0025] (5) the third warp uses modified sorona filament, which not only gives the fabric good resilience, but also makes the warp have waterproof performance, prevents the moisture absorbed by the antibacterial and heating layer from gathering in the yarn, causes the strength of the yarn to decrease, and at the same time, causes the moisture to be unable to be converted into heat energy in time.

[0026] (6) The pre-shrinking finishing process is adopted, so that the sorona filaments in the main body of the fabric are shrunk first, the weft density of the fabric is increased, then the low-temperature setting and high-temperature setting two-step setting processes are adopted, the main body of the fabric is fluffy and flat through the low-temperature setting, and the main body of the fabric is shrunk more in the width direction through the high-temperature setting, so that the fabric is overall crisp and has a sticky feeling, is tight and windproof, and the tear resistance of the fabric is also increased.
