Description

Technical Field

[0001] The utility model generally relates to the field of spinning production, in particular to a polyester POY / DTY composite yarn texturizing device. Background Art

[0002] At present, domestic polyester filaments are mainly produced by large-capacity melt direct spinning technology, and most of the products are coarse denier conventional varieties, which makes conventional varieties cheap and competitive. On the other hand, with the improvement of living standards in recent years, people have put forward more requirements for the functionality of the clothes they wear, such as comfort, novelty, crispness and warmth. This requires more diversified requirements on the fabric structure and the selection of raw materials. Only by developing high value-added differentiated functional filament products can we meet the changing market. Composite yarns have different styles, functions, and excellent wearing performance, which are favored by customers. Therefore, it is an inevitable trend to develop composite differentiated filament products. Polyester POY / DTY composite yarn is made of two different specifications of polyester POY as raw materials. The fabric woven with composite yarn has a higher wicking effect, and the fabric has excellent moisture absorption and perspiration resistance. It is the preferred fabric for thermal underwear and has broad development prospects.

[0003] However, the existing texturizing machines can only process polyester POY yarns into DTY yarns through false twisting, but cannot process polyester POY / DTY composite yarns. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a device for texturizing polyester POY / DTY composite yarn.

[0005] In a first aspect, the utility model provides a polyester POY / DTY composite yarn texturizing device, the polyester POY / DTY composite yarn texturizing device comprising:

[0006] A shredder, wherein the original silk bundle is divided into a first silk bundle and a second silk bundle after passing through the shredder;

[0007] a first roller, the first tow and the second tow passing around the first roller;

[0008] The DTY yarn conveying mechanism comprises a first heat box, a cooling plate and a false twister, and the first yarn bundle passing through the first roller passes through the first heat box, the cooling plate and the false twister in sequence;

[0009] The POY yarn conveying mechanism comprises a first yarn guide and a second yarn guide, and the second yarn bundle passing through the first roller passes through the first yarn guide and the second yarn guide in sequence;

[0010] The composite yarn guide is used for combining the first yarn bundle passing through the DTY yarn delivery mechanism and the second yarn bundle passing through the POY yarn delivery mechanism.

[0011] According to the technical solution provided in the embodiment of the present application, the original tow is divided into a first tow and a second tow by a tow cutter, and the first tow passing through the DTY yarn conveying mechanism and the second tow passing through the POY yarn conveying mechanism are compounded into a composite tow at a composite yarn guide, thereby processing polyester POY / DTY composite yarn, diversifying products, increasing product added value, and improving economic benefits.

It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0015] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] Please refer to Figure 1 The utility model discloses a polyester POY / DTY composite yarn texturizing device, which comprises: a slitter 10, wherein the original yarn bundle is divided into a first yarn bundle 51 and a second yarn bundle 52 after passing through the slitter 10; a first roller 20, wherein the first yarn bundle 51 and the second yarn bundle 52 pass around the first roller 20; a DTY yarn conveying mechanism 30, which comprises a first heat box 31, a cooling plate 32 and a false twister 33, wherein the first yarn bundle 51 passing through the first roller 20 passes through the first heat box 31, the cooling plate 32 and the false twister 33 in sequence; a POY yarn conveying mechanism 40, which comprises a first yarn guide 41 and a second yarn guide 42, wherein the second yarn bundle 52 passing through the first roller 20 passes through the first yarn guide 41 and the second yarn guide 42 in sequence; and a composite yarn guide 11, wherein the first yarn bundle 51 passing through the DTY yarn conveying mechanism 30 and the second yarn bundle 52 passing through the POY yarn conveying mechanism 40 are combined on the composite yarn guide 11.

[0017] Furthermore, a second heat box 15 is included, and the first filament bundle 51 and the second filament bundle 52 after being twisted pass through the second heat box 15 together to form a composite filament bundle.

[0018] Furthermore, a second roller 12, a network nozzle 13 and a third yarn guide 14 are provided between the second heat box 15 and the composite yarn guide 11, and the first yarn bundle 51 and the second yarn bundle 52 after being twisted pass through the second roller 12, the network nozzle 13 and the third yarn guide 14 in sequence.

[0019] Furthermore, an oiling roller 18 is included, and the composite filament bundle flowing out of the second heat box 15 passes through the oiling roller 18 .

[0020] Furthermore, a third roller 16 and a wire sensor 17 are provided between the oiling roller 18 and the second heat box 15 , and the composite wire bundle therefore passes through the third roller 16 and the wire sensor 17 .

[0021] Furthermore, it also includes a winding mechanism 19 for winding the composite filament bundle passing through the oiling roller 18 .

[0022] In the embodiment of the utility model, the existing texturing machine has only the DTY yarn conveying mechanism 30 but no POY yarn conveying mechanism 40, and can only process the polyester POY yarn into DTY yarn by false twisting, but cannot process the polyester POY / DTY composite yarn.

[0023] The present application transforms the existing texturizing machine, adds a POY yarn conveying mechanism 40, and uses different processing routes to make a strand of polyester POY yarn become polyester DTY yarn after texturizing, and then combine it with another strand of untexturized polyester POY yarn to form a composite yarn, thereby diversifying the products, increasing the added value of the products, and improving the economic benefits.

[0024] The original tow is divided into a first tow 51 and a second tow 52 by setting a wire cutter 10, so that the first tow 51 and the second tow 52 can be transported separately. The first roller 20 is set so that the first tow 51 passes through the DTY yarn conveying mechanism 30 and the second tow 52 passes through the POY yarn conveying mechanism 40 to form a double yarn path. The first tow 51 is stretched by the DTY yarn conveying mechanism 30 to become a polyester DTY yarn. The second tow 52 is not stretched by the POY yarn conveying mechanism 40 and is a polyester POY yarn. The first tow 51 and the second tow 52 are combined at the composite yarn guide 11. The combined first tow 51 and the second tow 52 pass through the second roller 12 and enter the network nozzle 13 for compounding to form a polyester POY / DTY composite yarn. The polyester POY / DTY composite yarn is then wound by the winding mechanism 19 after passing through the second hot box 15, the third roller 16, the yarn sensor 17 and the oiling roller 18.

[0025] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
