Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, and in particular to a spray-down yarn. Background Technology

[0002] With the development of the times and the progress of technology, people's requirements for clothing, food, housing and transportation are getting higher and higher. Sprayed yarn, as a fluffy, soft and warm yarn, is widely used in clothing fabrics. In the actual production of traditional sprayed yarn, disordered fibers are first sprayed into a net, and then the net is woven into yarn. In actual use, this traditional product sometimes causes the yarn to compact due to the tensile characteristics of the net structure under repeated stress, resulting in a decrease in warmth. To address this issue, our sister company has developed a sprayed yarn CN 210127289 U. This product adds a core yarn structure to the traditional sprayed yarn, resulting in better overall strength. It also limits the stretching length of the net and reduces the compaction problem caused by excessive stretching. However, after long-term use, customers have reported that due to the process of sprayed yarn, fibers often come out of the net. Moreover, customers hope to further improve the overall softness and fluffiness without reducing the current warmth performance. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a sprayed yarn that has a lighter and fluffier texture than traditional sprayed yarn while solving the problem of spun yarn.

[0004] To solve the above-mentioned technical problems, the present invention provides a spray-blown yarn, which includes a core yarn, a pile layer, and an outer sheath. The core yarn is formed by twisting and winding multiple low-elasticity filaments. The pile layer is composed of disordered short fibers, which include two types: one type is a base yarn composed of short fibers that are twisted between the low-elasticity filaments during the twisting and winding process and short fibers whose roots are inserted into the dynamic gaps between the monofilaments that make up the low-elasticity filaments; the other type is a free-floating filament composed of short fibers that are adhered and entangled with the base yarn. The outer sheath is a high-elasticity filament, which is twisted and wound around the outside of the pile layer in the opposite direction to the twisting direction of the core yarn.

[0005] In a preferred embodiment of this utility model, the filaments constituting the core wire have a specification of 30D to 150D and each filament is composed of no less than 16 monofilaments.

[0006] In a preferred embodiment of this utility model, the disordered short fibers include polyester fibers, nylon fibers, cotton fibers, viscose fibers, and bamboo fibers.

[0007] In a preferred embodiment of this invention, the length of the disordered short fibers is 5-15 mm.

[0008] In a preferred embodiment of this utility model, the core wire is twisted in the S direction and the number of twists is 10 to 100.

[0009] In a preferred embodiment of this utility model, the twisting direction of the outer sheath is Z-direction, and the number of twists is 10 to 50.

[0010] The beneficial effects of this utility model are as follows: This utility model further optimizes the existing production process of sprayed yarn. Instead of using a mesh belt to retain disordered short fibers, it utilizes the core yarn during the twisting and winding process to encase the short fibers in the middle of the core yarn to form a base yarn. Then, the hooking and adhesion of the base yarn is used to retain the free velvet on the outer layer to form a stable covering structure. This structure is further stabilized by using an outer wrapping yarn for reverse wrapping. In actual use, this yarn is found to be not only lighter and fluffier with less surface velvet shedding, but also has a distinct fuzzy feel and obvious surface velvet characteristics. Its skin-friendly properties are also superior to traditional sprayed yarn, perfectly meeting the demanding requirements of customers. Attached Figure Description

[0017] Example 1

[0018] A type of spun yarn, comprising: a core yarn 1, a pile layer 3, and an outer sheath 2. The core yarn 1 is formed by twisting two 30D16F polyester low-elasticity filaments in the S-direction with a twist count of 10. The pile layer 2 is composed of disordered short fibers formed by mixing polyester short fibers and viscose short fibers with a length of 5-15mm in a 1:1 ratio. The disordered short fibers of the pile layer 2 include two types: one type is a base yarn composed of short fibers that are entangled between the low-elasticity filaments during the twisting and winding process and short fibers whose roots are inserted into the dynamic gaps between the monofilaments that make up the low-elasticity filaments; the other type is a free pile composed of short fibers that are adhered and entangled with the base yarn. The outer sheath 2 is a PBT high-elasticity filament, which is twisted in the Z-direction and wound around the outside of the pile layer 3 with a twist count of 30.

[0019] Example 2

[0020] A type of sprayed yarn, comprising: a core yarn 1, a pile layer 3, and an outer wrapping yarn 2. The core yarn 1 is formed by twisting two 100D24F polyester low-elasticity filaments in the S-direction with a twist count of 75. The pile layer 2 is composed of disordered short fibers made of polyester fibers, cotton fibers, and bamboo fibers with a length of 5-15mm in a 2:1:1 ratio. The disordered short fibers of the pile layer 2 include two types: one type is a base yarn composed of short fibers that are entangled between the low-elasticity filaments during the twisting and winding process and short fibers that are inserted into the dynamic gaps between the monofilaments that make up the low-elasticity filaments at their roots; the other type is a free-flowing pile composed of short fibers that are adhered and entangled with the base yarn. The outer wrapping yarn 2 is a single polyester high-elasticity filament, which is twisted in the Z-direction and wound around the outside of the pile layer 3 with a twist count of 50.

[0021] Example 3

[0022] A type of spun yarn, comprising: a core yarn 1, a pile layer 3, and an outer sheath 2. The core yarn 1 is formed by twisting two 150D36F polyester low-elasticity filaments in the S-direction with a twist count of 100. The pile layer 2 is composed of disordered short fibers made up of nylon fibers and viscose fibers with a length of 5-15mm in a 1:1 ratio. The disordered short fibers of the pile layer 2 include two types: one type is a base yarn composed of short fibers that are entangled between the low-elasticity filaments during the twisting and winding process and short fibers that are inserted into the dynamic gaps between the monofilaments that make up the low-elasticity filaments at their roots; the other type is a free pile composed of short fibers that are adhered and entangled with the base yarn. The outer sheath 2 is a single polyester high-elasticity filament, which is twisted in the Z-direction and wound around the outside of the pile layer 3 with a twist count of 10.

[0023] The preparation process of Examples 1 to 3 includes the following steps:

[0024] The first step is to select the raw materials for core yarn 1, outer sheath yarn 2, and woolen layer 3 according to production requirements;

[0025] The second step involves simultaneously inserting the two low-elasticity filaments that make up the core wire 1 into the opening of the forming tube 5. The included angle between the two filaments is 120°. After being twisted and wound in the Z-direction inside the forming tube 5, the two low-elasticity filaments are led out from the bottom of the tube.

[0026] The second step involves drying the short fibers and feeding them into a combing box for combing by a combing mechanism. Then, the short fibers are randomly sprayed into the forming tube 5 from above the tube opening from the combing box outlet 4. During the twisting and winding process of the low-elasticity filament, some of the short fibers are wrapped around the twisted core yarn. At the same time, some of the short fibers will pierce into the dynamic gaps between the monofilaments formed by the twisting and winding of the low-elasticity filament. These two types of short fibers constitute the base yarn of the pile layer 2. Some of the short fibers will also be wrapped around and adhered to the base yarn under the action of the wind in the tube, eventually forming the free velvet on the surface.

[0027] The third step involves twisting the outer yarn 2S onto the yarn drawn from the bottom of the tube, binding the free velvet adhering to the bottom yarn to the core yarn, and then dropping the yarn to produce the finished sprayed yarn.

[0028] The three types of sprayed yarn manufactured in the above manner are not only fluffy, soft and warm, but also have a significant velvety and feathery feel on the surface, excellent skin-friendliness, and the fluff is not easy to fall off. In comparison, the product of Example 1 has a relatively small base yarn density, is more fluffy overall and has the best surface feathery feel, while the product of Example 3 has a relatively large base yarn density, a larger density of free velvet on the surface, and a relatively stronger velvety feel.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
