Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and particularly relates to a wear-resistant and tear-resistant fabric, a preparation method thereof, and an application thereof. Background Art

[0002] With the continuous improvement of people's requirements for clothing quality and comfort, in addition to meeting the requirements of comfort and durability, clothing fabrics should also have more functions, such as lightweight, waterproof, tear-resistant, breathable and moisture-permeable, and portability, etc.

[0003] At present, in order to ensure the lightweight requirement of the fabric, yarns with relatively fine yarn counts and relatively low gram weights are usually selected for fabric weaving. This results in the fabric obtained by weaving meeting the lightweight requirement, but having poor tear resistance and wear resistance, and thus it is difficult to be applied in situations requiring high wear resistance and high tear resistance, such as outdoor clothing.

[0004] Therefore, in view of the above technical problems, it is of great significance to develop a wear-resistant and tear-resistant fabric that has high wear resistance and high tear resistance while maintaining lightweight. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a wear-resistant and tear-resistant fabric, a preparation method thereof, and an application thereof. By selecting three kinds of yarns, namely nylon yarn, polyester yarn, and polyarylate yarn, for matching and optimizing the technological process, the fabric obtained by weaving has excellent wear resistance and excellent tear resistance while maintaining lightweight, and is suitable for preparing outdoor clothing.

[0041] The technical solutions of the present invention will be further described below through specific implementation manners. Those skilled in the art should understand that the described embodiments are only for helping to understand the present invention and should not be regarded as specific limitations to the present invention. Moreover, for the raw materials and steps involved in the following specific implementation manners, if there is no special description, they are all conventional materials and conventional operations in the art.

[0042] Specifically, the information of some raw materials involved in the following specific implementation manners is as follows:

[0043] (1) Caustic soda: Purchased from Yuanlu Chemical Co., Ltd., Cangzhou, Hebei.

[0044] (2) Sizing agent TF-127, scouring emulsifier 120C, penetrant TF-JFC, dispersing and leveling agent TF-210T, hydrophilic softener HD-812, water and oil repellent HD-6095, penetrant HD-JFC, and bridging agent HD-30b: All purchased from Zhejiang Transfar Group.

[0045] (3) Cationic turquoise blue XF 100%, Longsheng red-100%, and Longsheng yellow Y 100%: Purchased from Zhejiang Longsheng Group.

[0046] (4) Glacial acetic acid: Purchased from Fuzhou Derun Chemical Co., Ltd.

[0047] Example 1

[0048] A wear-resistant and tear-resistant fabric is woven from warp yarns and weft yarns.

[0049] Among them, the warp yarns are nylon 20D / 7F SD DTY and polyester 25D / 72F SD DTY, and the weft yarns are nylon 20D / 8F SDDTY and polyarylate 25D / 5F SD FDY.

[0050] The preparation method of the wear-resistant and tear-resistant fabric includes the following steps:

[0051] (1) Fabric design: First, calculate the total number of warp beams as 163 (set value) × 166 / 2.54 ≈ 10640 (the calculation formula is warp density × full width / 2.54). Then, calculate the weaving weft density as 170 × (1 - 6%) ≈ 160 (the calculation formula is grey fabric weft density × (1 - weaving shrinkage)). The shrinkage value of nylon is about 6%. The weaving width is 184 cm (estimated value). Then, the reed count is 10640 / 183.5 / 2 ≈ 29 teeth (the calculation formula is total number of warp beams / weaving width / 2). The specific grey fabric process table is shown in Table 1:

[0052] Table 1

[0053]

[0054]

[0055] (2) Warping: First, estimate the number of yarns and yarn consumption required to weave 1000 m of grey fabric. The actual warping length required is 1000 × (1 + 10% (loss)) = 1100 m. The number of each warping is 10640 / 10 (warping with 10 warp beams) = 1064 pieces;

[0056] The yarn consumption of warp nylon 20D / 7F SD DTY: The yarn consumption per meter of warp nylon 20D / 7F SD DTY is 22.5 g. The number of pieces is 10640 × 18 / 19 = 10080 pieces. The total yarn consumption of warp nylon 20D / 7F SD DTY is 22.5 g × 1100 m = 24750 g = 24.75 kg. Warp 6 warp beams with 1680 pieces per warp beam;

[0057] The yarn consumption of warp polyester 25D / 72F SD DTY: The yarn consumption per meter of warp polyester 25D / 72F SD DTY is 1.6 g. The number of pieces is 10640 / 19 = 560 pieces. The total yarn consumption of warp polyester 25D / 72F SD DTY is 1.6 g × 1100 m = 1760 g = 1.76 kg. Warp 1100 m with 640 pieces per warp beam;

[0058] The yarn consumption of weft nylon 20D / 8F SD DTY: The yarn consumption of weft nylon 20D / 8F SD DTY is 24.3 g. The total yarn consumption of weft nylon 20D / 8F SD DTY is 24.3 g × 1100 m = 26730 g = 26.73 kg;

[0059] The yarn consumption of weft polyarylate 25D / 5F SD FDY: The yarn consumption per meter of weft polyarylate 25D / 5F SD FDY is 1.8 g. The total yarn consumption of weft polyarylate 25D / 5F SD FDY is 1.8 g × 1100 m = 1980 g = 1.98 kg;

[0060] (3) Combine and warp: Use a combining and warping machine to combine 9 beam heads into one beam head (note that the warp tension should be uniform).

[0061] (4) Threading and reed insertion: As Figure 1 shown, thread in the order of 1, 2, 3, 4, 5, 6, and insert the reed at 2 ends per dent, 10640 / 2 = 5320 dents.

[0062] (5) Weaving: First, pull the beamed and reed-inserted beam head to the water jet loom. Set the water jet angle of the water jet loom to 100°, the yarn changing angle to 110°, and the leading angle settings are: 15° for polyester, and the scissor angle: 23° - 26°. Then start weaving.

[0063] (6) Cold pad-batch: Prepare 300 L of the solution in a storage tank by mixing caustic soda at 60 g / L, desizing agent TF-127 at 20 g / L, scouring emulsifier 120C at 20 g / L, penetrant TF-JFC at 5 g / L and water. Then heat it up to 60°C. Pass the unwound grey fabric flatly through the storage tank, and then fully wet it through a padding mangle and roll it into a roll. Stack it at room temperature for 24 h at a speed of 10 revolutions / min.

[0064] (7) Desizing: Directly feed the cold pad-batch fabric into the dyeing vat for desizing. The temperature is 95°C at a speed of 30 m / min, and the padding mangle pressure is 2 kg. The desizing solution contains caustic soda at 40 g / L, desizing agent TF-127 at 12 g / L, scouring emulsifier 120C at 10 g / L, penetrant TF-JFC at 5 g / L and water (note that there should be no creases or uneven edges on the fabric surface). After desizing, test the desizing effect: Immerse the desized fabric in a 3% dyebath of cationic turquoise blue XF for 5 min and take it out to check whether the fabric surface is evenly dyed.

[0065] (8) Overflow dyeing: According to the dyeing formula: 0.05% of Longsheng red 100%, 0.5% of Longsheng yellow Y 100%, 2 g / L of glacial acetic acid, 1.5% of acid leveling agent TF-210T and water, stir well. The liquor ratio is 1:10. Feed the grey fabric into the dyeing vat at room temperature. Heat it up according to the set temperature rising curve: rise to 60°C at 1°C / min, hold for 20 min, then rise to 80°C at 1.5°C / min, hold for 20 min, and then rise to 100°C at 0.5°C / min and hold for 50 min for dyeing. After the holding is completed, cool it down to 60°C at 1.5°C / min and wash the fabric with cold water for 10 min. After dyeing, take samples for color matching. After color matching, use 2 g / L of fixing agent and 1 g / L of glacial acetic acid to rise to 80°C at 2°C / min for 20 min for fixation, washing away the floating color on the fabric surface while fixing, giving the fabric good color fastness.

[0066] (9) Dehydration: Put the dyed grey fabric into a dehydrator for dehydration.

[0067] (10) Fixing: Dilute and mix 4 kinds of auxiliaries evenly according to 40 g / L of high waterproof and oil-proof agent HD-6095, 5 g / L of crosslinking agent HD-30b, 10 g / L of hydrophilic softener HD-812, and 5 g / L of penetrant HD-JFC to prepare 100 L and place it in the material tank (the solvent is water). After dehydrating the embryo cloth, pass it through the material tank, wet it, and then fully extrude it through the calender (the calender pressure is 2.5 kg), and then enter the oven. The process parameters are 160 °C × 40 m / min × 600 cfm × 4% (temperature × speed × air volume × overfeed). After coming out of the oven, cool it through the cooling roller and then check the fabric surface effect to obtain the wear-resistant and tear-resistant fabric.
