Description

Technical Field

[0001] The utility model relates to an easily colored DTY fancy twisted yarn, belonging to the technical field of polyester DTY filaments. Background Art

[0002] The fancy twisted yarn is made of two strands of filaments that have been subjected to composite deformation processing and have irregular left and right twists. The fabric produced has a strong hemp effect. However, the two filaments in the current fancy twisted yarn are only reinforced by twisting together. However, if a linen-like effect is required, a stronger twist is required, and different twist directions are also required. Then the phenomenon of untwisting will occur. In addition, the conventional polyester used has the characteristic of being difficult to color. How to prepare a fancy twisted yarn that is easy to color and has a relatively stable twist has become a problem to be solved. Utility Model Content

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the hot-melt polyester filament is a sheath-core structure, including a sheath layer and a core layer, the sheath layer is low-melting point polyester with a melting point of 85-110°C; the core layer is conventional polyester with a melting point of 255°C.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the twist of the Z-direction twisting section 1 and the S-direction twisting section 2 is 1200-1600 T / m.

[0011] On the basis of the above scheme and as a preferred scheme of the above scheme: the first polyester multifilament further includes cationic polyester DTY filaments twisted with easily colorable polyester DTY filaments.

[0012] The beneficial effects of the utility model are as follows: the easily colored DTY fancy twisted yarn of the utility model has a bonding point between the Z-direction twisting section and the S-direction twisting section, thereby reducing the occurrence of untwisting.

[0013] Figure 1 It is a structural schematic diagram of the easily colored DTY twisted yarn involved in Example 1.

[0014] The markings in the figure are as follows: 1-Z-direction twisting section; 2-S-direction twisting section. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1

[0017] Combination Figure 1 The embodiment is described in detail. The easily colored DTY twisted yarn involved in the embodiment comprises a Z-direction twisting section 1 and an S-direction twisting section 2 arranged alternately; the Z-direction twisting section 1 is formed by twisting the first polyester multifilament and the second polyester multifilament in the Z direction; the S-direction twisting section 2 is formed by twisting the first polyester multifilament and the second polyester multifilament in the S direction.

[0018] The first polyester multifilament includes easily colored polyester DTY filaments, and the second polyester multifilament includes easily colored DTY filaments and hot-melt polyester filaments arranged in parallel. The connection between the Z-direction twisting section 1 and the S-direction twisting section 2 has a bonding point.

[0019] The lengths of the Z-direction twisting section 1 and the S-direction twisting section 2 can be the same or different, and can be adjusted according to production needs. The lengths of different Z-direction twisting sections 1 can also be the same or different, and their lengths can be set according to actual needs.

[0020] Since the second polyester composite yarn uses a hot-melt polyester filament, and the hot-melt polyester filament is a skin-core structure, including a skin layer and a core layer, the skin layer is a low-melting point polyester with a melting point of 85-110°C; the core layer is a conventional polyester with a melting point of 255°C. When preparing the easy-to-color DTY filament involved in this embodiment, a heating treatment can be performed at the position where the Z-direction twisting section 1 and the S-direction twisting section 2 are switched, so that the low-melting point polyester on the surface layer is melted, so that the first polyester composite yarn and the second polyester composite yarn can be bonded to each other.

[0021] Further, the fineness of the easily colored DTY filament is 75-96D / 144-288F. In this embodiment, 75D / 144F is selected.

[0022] Furthermore, the twist of the Z-direction twisting section 1 and the S-direction twisting section 2 is 1200-1600 T / m. In this embodiment, the twist of the Z-direction twisting section 1 is selected to be 1200 T / m, and the twist of the S-direction twisting section 2 is selected to be 1600 T / m. Due to the strong twist, the prepared fabric has a linen-like effect.

[0023] Embodiment 2

[0024] The easily colorable DTY fancy twisted yarn involved in this embodiment is different from that in the first embodiment in that the first polyester multifilament further comprises cationic polyester DTY filaments twisted with the easily colorable polyester DTY filaments. The cationic polyester DTY filaments used may have different color effects from other polyester filaments, thereby forming two-color DTY fancy twisted yarns.

[0025] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
