Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and particularly relates to fiber structures, fiber webs, and latex air fibers.

Background Art

[0002] Currently, for example, textiles made of sponge, hard cotton, upright cotton, or ordinary latex fibers have relatively soft fibers, and a certain strength is obtained by the binding force between the fibers, but since the strength is very low, it affects the supportability, elasticity, washability, and durability of the textile.

Summary of the Invention

[0003] The object of the present invention is to solve the problems existing in the prior art that the bonding strength between the fibers of the textile is relatively low and affects the supportability, elasticity, washability, and durability, and to provide a fiber structure, a fiber web, and a latex air fiber with improved characteristics such as supportability, elasticity, washability, and durability, and excellent environmental properties.

Means for Solving the Problems

[0004] To achieve the above object, the present invention adopts the following technical solutions.

[0005] In a first aspect, the present invention provides a fiber structure comprising 100% polyester material and configured as Ω-shaped profiled fibers.

[0006] Preferably, the thickness of the fiber structure is set to 3 Denier.

[0007] Preferably, the length of the fiber structure is set to 51 mm.

[0008] In a second aspect, the present invention provides a fiber web composed of the fiber structure described in the first aspect of the present invention.

[0009] Preferably, the fiber structures in the fiber web are repeatedly needle-punched by barb needles. The needles penetrate the fiber web, and the barbs move the fiber structures on the surface and secondary surface of the fiber web perpendicular to the plane of the fiber web, causing the fiber structures to displace vertically relative to each other, clamp together, and form the compressed fiber web.

[0010] Preferably, the fiber structures in the fiber web are repeatedly needle-punched by at least two barb needles.

[0011] Preferably, the fiber web has a basis weight of 500 g / m 2 , a thickness set to 1 cm, a delivery speed of needle punching by the needles of 3 m / min, and a needle punching frequency set to 200 times / min.

[0012] Preferably, the fiber web has a basis weight of 1200 g / m 2 , a thickness set to 2 cm, a delivery speed of needle punching by the needles of 2.3 m / min, and a needle punching frequency set to 140 times / min.

[0013] Preferably, the fiber web has a basis weight of 1800 g / m 2 , a thickness set to 3 cm, a delivery speed of needle punching by the needles of 1.7 m / min, and a needle punching frequency set to 85 times / min.

[0014] In a third aspect, the present invention provides a latex air fiber composed of the fiber web described in the second aspect of the present invention.

Advantages of the Invention

[0015] The fiber structure, fiber web, and latex air fiber according to the present invention have the following beneficial effects.

[0016] 1. The fiber structure according to the present invention employs Ω-shaped profiled fibers containing 100% polyester material, which has the following advantages compared to round fibers. Wrinkle resistance and snag resistance: Since the elastic modulus of the profiled fiber is higher than that of the circular cross-section fiber, the deformation resistance is relatively strong, and it has excellent wrinkle resistance effect. Fluffy feeling and breathability: The covering property and fluffy feeling of the profiled fiber are superior to those of ordinary synthetic fibers. The fabric is thicker, fluffy, and has a lightweight touch with a plump feeling. By using Ω-shaped profiled fibers, the cross-section becomes more complex, the degree of fiber profile increases, and the fluffy feeling and breathability of the fiber and fabric are further improved. Pilling resistance and abrasion resistance: By using Ω-shaped profiled fibers, the surface area of the fiber increases, the bonding force between the fibers in the tow increases, and the pilling phenomenon is significantly reduced.

[0017] 2. The fiber structure according to the present invention can be manufactured from highly elastic fibers by a two-component polymerization process, does not contain formaldehyde, is less likely to yellow, has high elasticity, does not deform, does not powderize, has good breathability, and has excellent environmental performance.

[0018] 3. The fiber web according to the present invention has a very environmentally friendly production process, does not contain chemical additives, does not use adhesives, is manufactured by physical changes, does not pollute the environment, and has zero emissions. Also, the pH value is neutral, it does not contain fluorescent agents, and is harmless to the skin.

[0019] 4. The latex air fiber according to the present invention has excellent antibacterial and anti-mite effects, is washable, resistant to washing, difficult to deform, and also has the resilience and pressure resistance of sponge and latex. It is most suitable for pillow fillings, mattress pads, children's and adult mattresses, Simmons mattresses, etc.

[0020] 5. The latex air fiber according to the present invention has no yellowing or powdering compared to sponges, has excellent support and elasticity, has very strong wash resistance, and compared to hard cotton and upright cotton, not only has excellent support, breathability, durability, and environmental friendliness, but also has a soft and elastic feel, does not pollute the environment compared to ordinary latex fibers, has high elasticity, excellent breathability, and no powdering.

Modes for Carrying Out the Invention

[0022] Hereinafter, the present invention will be described in more detail with reference to the drawings and specific embodiments. Example 1

[0023] As shown in FIG. 1, this example provides a fiber structure composed of 100% polyester material and configured as an Ω-shaped profiled fiber. The fiber structure 1 may be a high-elastic fiber by a two-component polymerization process. Specifically, the thickness of the fiber structure 1 is set to 3 Denier. Specifically, the length of the fiber structure 1 is set to 51 mm. Example 2

[0024] Referring to FIGS. 1 and 2 together, this example provides a fiber web composed of the fiber structure 1 of Example 1. Specifically, the fiber structures 1 of the fiber web 2 are repeatedly needle-punched by barb needles. The needles pierce the fiber web 2, and the barbs move the fiber structures 1 on the surface and secondary surface of the fiber web 2 perpendicular to the plane of the fiber web 2. The fiber structures 1 displace up and down to clamp each other, forming a compressed fiber web 2. Specifically, the fiber structures 1 of the fiber web 2 are repeatedly needle-punched by at least two barb needles. Here, the needles may have a triangular or other cross-sectional shape and may be provided with barbs on the edges. The fiber web 2 may be a fiber web 2 taken out from a cross-laying device or an air-laying device. When the fiber web 2 is supplied to a needle-punching machine, it is very fluffy, and a certain strength is obtained only by the binding force between the fibers, but the strength is very low. When a plurality of needles pierce the fiber web 2, the barbs of the needles move the fibers on the surface and secondary surface of the fiber web 2 from the plane direction of the fiber web 2 to the vertical direction of the fiber web 2, displacing the fiber structure 1 up and down. The fiber structure 1 displaced up and down presses the fiber web 2, clamping and compressing the fiber structures 1 in the fiber web 2. Specifically, the fiber web 2 has a basis weight of 500 g / m 2 and is set to a thickness of 1 cm. The delivery speed of the needle punch by the needles is 3 m / min, and the needle punch frequency is set to 200 times / min. Specifically, the fiber web 2 has a basis weight of 1200 g / m 2 and is set to a thickness of 2 cm. The delivery speed of the needle punch by the needles is 2.3 m / min, and the needle punch frequency is set to 140 times / min. Specifically, the fiber web 2 has a basis weight of 1800 g / m 2 and is set to a thickness of 3 cm. The delivery speed of the needle punch by the needles is 1.7 m / min, and the needle punch frequency is set to 85 times / min. Example 3

[0025] Referring to FIGS. 1 to 4, the present embodiment provides a latex air fiber composed of the fiber web 2 described in Embodiment 2. Here, the latex air fiber 3 may be rectangular, and its thickness may be set to 1 cm to 6 cm.
