Abstract
Description
Technical Field
[0001] This utility model relates to a linen-like polyester composite yarn, belonging to the technical field of polyester composite yarn. Background Technology
[0002] Fabrics made from flax plant fibers are generally used to make casual wear and workwear. Finely spun flax fabrics, after special finishing processes, are used to make mid-to-high-end summer clothing and are very popular in the market. The advantages of flax fabrics are extremely high strength, excellent moisture absorption, heat conduction, and breathability. The disadvantages are that they are not very comfortable to wear, have a relatively rough and stiff appearance, wrinkle easily, and have poor drape. Moreover, due to the preference for natural fabrics, the supply and demand of flax raw materials has become unbalanced, and prices have been rising continuously. Clothing made from natural flax fabrics has seen price increases due to cost pressures, significantly impacting sales. Therefore, how to prepare a flax-like polyester composite yarn for making flax-like fabrics, thereby reducing the cost of flax-like fabrics, has become a problem to be solved. Utility Model Content
[0003] The purpose of this invention is to provide a linen-like polyester composite yarn that achieves a linen-like wrinkling effect through strong twisting.
[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present invention relates to a linen-like polyester composite yarn, comprising strongly twisted polyester DTY filaments and strongly twisted nylon 6DTY filaments twisted together. The twist direction of the high-twist polyester DTY filament, the twist direction of the high-twist nylon 6DTY filament, and the twist direction of the high-twist polyester DTY filament and the high-twist nylon 6DTY filament twisted together are the same. The cross-section of the monofilament in the high-twist nylon 6DTY filament is circular, including a nylon 6 core layer and an antistatic nylon 6 part and an antibacterial nylon 6 part disposed on the outside of the nylon 6 core layer.
[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the high-twist polyester DTY filament and the high-twist nylon 6DTY filament have a twist of 1200-1500 twists per meter.
[0006] Based on the above scheme and as a preferred option, the twist of the high-twist polyester DTY filament and the high-twist nylon 6DTY filament is 600-800 twists per meter.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the high-twist polyester DTY filament has a first monofilament, a second monofilament and a third monofilament, the first monofilament has a triangular cross-section, the second monofilament has a cross-shaped cross-section, and the third monofilament has a straight cross-section.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: each monofilament in the high-twist polyester DTY filament has honeycomb-like micropores on its surface.
[0009] The beneficial effects of this utility model are as follows: The linen-like polyester composite yarn involved in this utility model, through the parallel twisting of highly twisted polyester DTY filaments and highly twisted nylon 6DTY filaments with the same twist direction, enables the yarn to have a good wrinkling effect when preparing fabric, achieving a linen-like effect. Furthermore, the antistatic and antibacterial nylon 6 portions of the nylon 6 filaments also provide antibacterial and antistatic effects to the composite yarn. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of the imitation linen polyester composite yarn involved in Example 1; Figure 2 This is a schematic diagram of the cross-sectional structure of a single filament in the high-twist nylon 6DTY filament involved in Example 1. Detailed Implementation
[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0012] Example 1 Combination Figure 1 This embodiment provides a detailed description. The linen-like polyester composite yarn involved in this embodiment includes two strongly twisted polyester DTY filaments 1 and nylon 6DTY filaments 2. The twist direction of the strongly twisted polyester DTY filament 1 and the twist direction of the strongly twisted nylon 6DTY filament 2 are the same as the twist direction of the strongly twisted polyester DTY filament 1 and the strongly twisted nylon 6DTY filament 2 when twisted together. The twist direction of the ply yarn is the same as the twist direction of the single yarn, further enabling the fabric prepared from this composite yarn to have a wrinkled effect, thus achieving a linen-like effect. The fineness of the strongly twisted polyester DTY filament 1 is 75D / 72F, and the fineness of the strongly twisted nylon 6DTY filament 2 is 75D / 48F.
[0013] The high-twist nylon 6DTY filament 2 has a circular cross-section and includes a nylon 6 core layer 21 and antistatic nylon 6 portions 22 and antibacterial nylon 6 portions 23 disposed on the outer side of the nylon 6 core layer 21. The antistatic nylon 6 portions 22 give the high-twist nylon 6DTY filament 2 an antistatic effect. This is because the polyester and nylon 6 used in this composite yarn have poor moisture absorption and are prone to static electricity; the use of antistatic nylon 6 portions can achieve an antistatic effect. Similarly, the use of antibacterial nylon 6 portions 23 can improve the antibacterial effect of the composite yarn.
[0014] Furthermore, the high-twist polyester DTY filament 1 and the high-twist nylon 6 DTY filament 2 have a twist of 1200-1500 twists per meter. In this embodiment, 1500 twists per meter is selected.
[0015] Furthermore, the twist of the high-twist polyester DTY filament 1 and the high-twist nylon 6DTY filament 2 is 600-800 twists per meter. In this embodiment, 800 twists per meter is selected.
[0016] Furthermore, during the twisting of the high-twist polyester DTY filament 1 and the high-twist nylon 6DTY filament 2, the high-twist nylon 6DTY filament 2 is stretched by 5% before twisting. The high-twist nylon 6DTY filament 2 has good elastic recovery, which makes the composite yarn have better wrinkling effect.
[0017] Example 2 The flax-like polyester composite yarn involved in this embodiment differs from that in Embodiment 1 in that: the high-twist polyester DTY filament 1 has a first monofilament, a second monofilament, and a third monofilament. The first monofilament has a triangular cross-section, the second monofilament has a cross-shaped cross-section, and the third monofilament has a straight cross-section. Each monofilament in the high-twist polyester DTY filament 1 has honeycomb-like micropores on its surface. The cross-shaped cross-section monofilament has excellent moisture absorption and wicking properties. The honeycomb-like micropores formed on the surface of each monofilament give the composite yarn excellent moisture absorption.
[0018] The number of the first, second, and third monofilaments is the same. In this embodiment, the fineness of the high-twist polyester DTY filament 1 is 75D / 72F, that is, the number of the first, second, and third monofilaments is 24 each.
[0019] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
