Description

Technical Field

[0001] This invention relates to the field of textile fabric products, specifically to an ice-feel modal fabric and its production method. Background Technology

[0002] Modal fiber is a regenerated cellulose fiber made from wood pulp made from European beech, spruce, etc., and then processed into fiber through a special spinning process. This fiber product can decompose naturally and is a green and environmentally friendly fiber.

[0003] Currently, in the production of cooling fabrics, as illustrated in Chinese patent application CN 107557980 A, a cooling clothing fabric is made using the following steps:

[0004] 1) Weaving: The fabric is a double-layer fabric with a weft knitting structure design. The front side of the fabric is made of Tencel fiber and jade fiber, and the reverse side is made of Modal fiber.

[0005] 2) Dyeing fabrics using reactive dyes and acid dyes;

[0006] 3) Fix the dyed fabric with color;

[0007] 4) The fabric is soaked in antibacterial finishing agent and cooling finishing agent for a cooling finish.

[0008] It demonstrates the basic process currently used to produce cooling or icy fabrics.

[0009] However, in terms of process, due to the different fibers, this double-layer fabric will have different effects on dyeing and subsequent padding, resulting in color inconsistency between the front and back sides; in addition, the double-layer fabric is also prone to insufficient uniformity in the padding effect of finishing agents and cooling finishing agents, resulting in poor hand feel. Summary of the Invention

[0010] Therefore, the present invention provides an ice-feel modal fabric and its production method, which solves the problems of existing ice-feel fabrics having a rough feel and insufficient delicacy.

[0011] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0012] A method for producing an ice-feel modal fabric includes the following steps:

[0013] a. Select modal fibers with a count of 40 or higher for weaving, then cut the fabric into the required width after weaving, distribution and finishing, and then prepare the fabric blank for use. The fabric blank is woven into jersey fabric.

[0014] b. Dye and fix the color of the cut fabric blanks;

[0015] c. Impregnate and finish the color-fixed fabric blank;

[0016] d. The impregnated fabric blank is dried, shaped, inspected, and packaged to obtain the fabric.

[0017] In step c above, a padding mechanism is used for padding. The padding mechanism includes a frame, a padding tank is provided on the frame, and several guide rollers are arranged on the frame for introducing and drawing the fabric blank into and out of the padding tank. A stretching assembly for weft knitting longitudinal / weft knitting transverse stretching of the fabric blank is provided on the frame above the padding tank.

[0018] Preferably, the stretching assembly includes one or more stretching roller groups disposed on the frame, the stretching roller groups being immersed in the padding tank, the stretching roller groups being inclinedly distributed along the conveying direction of the fabric blank, and the rotation direction of the stretching roller groups being outward toward the width of the fabric blank to stretch the fabric blank along its weft knitting longitudinal / weft knitting transverse.

[0019] Preferably, the stretching assembly includes a stretching wheel disposed on the frame, the stretching wheel being immersed in the rolling tank, and the diameter of the stretching wheel gradually decreasing from its center to both sides.

[0020] Preferably, the extension wheel has a short shaft end and a long shaft end with inconsistent axial heights, and the axial height gradually increases from the short shaft end to the long shaft end.

[0021] Preferably, the immersion tank is equipped with a circulation pump and circulation pipes for internal immersion liquid circulation.

[0022] Preferably, in step c above, the impregnation process uses 60-80 g / L of ice-feeling silicone oil and 1.0-2.0 g / L of JM penetrant.

[0023] Preferably, in step a above, the raw material used is 50s / 1 modal fiber, woven into a 30-inch 28G single-sided fabric with a yarn length parameter of 14cm / 50N, and the parameters of the jersey fabric are 120g / m². 2 .

[0024] Preferably, in step d above, a Santex loose dryer is used for drying, with a pressure roller of 3KG, a liquid carry-over rate of 63-68%, and a drying temperature of 150-180℃.

[0025] A type of ice-feel modal fabric is produced using the ice-feel modal fabric production method described above.

[0026] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0027] In the production of this technical solution, Lenzing's high-count Modal fiber is selected as the raw material, and the resulting jersey fabric has a refreshing feel, is delicate against the skin, is silky and comfortable, and has good wear resistance.

[0028] The weaving process employs plain weft knitting. By improving the padding equipment and process, the fabric blank is stretched in a direction different from the conveying direction during padding, creating a stretching effect in the padding tank that differs from the conveying direction. Before padding, the fabric blank can be split along the weft knitting longitudinal direction or the weft knitting transverse direction as needed, so that it can form a continuous fabric blank structure according to the different extensibility of plain weft knitted fabrics. Then, the stretching component creates a stretching effect different from the conveying direction, ensuring uniform adhesion of the cooling silicone oil during padding. The resulting product has excellent fineness and is cool and comfortable. Attached Figure Description

[0034] The following will describe in detail the implementation of the present invention with reference to specific embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] Example 1

[0036] A method for producing an ice-feel modal fabric includes the following steps:

[0037] a. Select 50-count modal fiber for weaving, then cut the fabric into the required width after weaving, distribution and finishing, and then prepare the fabric blank. The fabric blank is woven into jersey fabric.

[0038] b. Dye and fix the color of the cut fabric blanks;

[0039] c. Impregnate and finish the color-fixed fabric blank;

[0040] d. The impregnated fabric blank is dried, shaped, inspected, and packaged to obtain the fabric.

[0041] In step c above, a padding mechanism is used for padding, and the padding mechanism is as follows: Figure 1 , Figure 2 As shown, the device includes a frame, on which an impregnation tank 1 is provided, and several guide rollers 11 arranged on the frame for introducing and drawing the fabric blank into and out of the impregnation tank 1. A stretching assembly for weft knitting longitudinal / weft knitting transverse stretching of the fabric blank is provided on the frame above the impregnation tank 1. Here, weft knitting longitudinal / weft knitting transverse refers to the orientation of the weft knitted texture of the jersey fabric after weft knitting. In production, the fabric blank, after being split, is continuous, and its length direction (i.e., the impregnation input and output direction) can be either weft knitting longitudinal or weft knitting transverse. When weft knitting longitudinal is used, its extensibility is greater, and the fabric blank's transmission speed can be greater than when weft knitting transverse is used. In this embodiment, weft knitting longitudinal is used.

[0042] Specifically, the stretching assembly includes a set of stretching rollers 2 mounted on the frame. The stretching rollers 2 are connected to a matching motor that drives their rotation, and the rotation direction is as follows: Figure 2 As shown, there should be no adverse force against the conveying direction of the fabric blank; the stretching roller group 2 is immersed in the padding tank 1, and the stretching roller group 2 is inclined along the conveying direction of the fabric blank, in a figure-eight shape. The figure-eight distributed stretching roller group 2 can form a certain stretching effect in both the weft knitting transverse and weft knitting longitudinal directions, while not excessively hindering the conveying of the fabric blank; and the rotation direction of the stretching roller group 2 is outward towards the width of the fabric blank so that the fabric blank is stretched along its weft knitting transverse direction. Here, "along its weft knitting transverse direction" does not mean completely towards this direction, but only that the fabric blank has an extension tendency in this direction.

[0043] Furthermore, the impregnation tank 1 is equipped with a circulation pump 3 and a circulation pipe 31 for internal impregnation liquid circulation. A relay box 32 is connected to the circulation pipe 31 for adding raw materials and serving as a buffer for the circulation of the impregnation liquid. This impregnation liquid circulation system ensures that the internal icing silicone oil is fully dispersed, further guaranteeing the uniformity of the impregnation process. Moreover, when the equipment is shut down and restarted, a certain period of circulation can prevent uneven distribution of the silicone oil. It also facilitates the addition of silicone oil.

[0044] Regarding specific parameters, in step c above, the impregnation uses 60-80g / L of ice-feeling silicone oil and 1.0-2.0g / L of JM penetrant; usable fabric products can be obtained by using parameters within the above range.

[0045] In step a above, the raw material used is 50s / 1 modal fiber, woven into a 30-inch 28G single-sided fabric with a thread length parameter of 14cm / 50N, and the parameters of the jersey fabric are 120g / m2.

[0046] In step d above, a Santex loose dryer is used for drying, with a pressure roller of 3KG, a liquid retention rate of 63-68%, and a drying temperature of 150-180℃, preferably 150℃, which can ensure good fabric setting effect.

[0047] In the production of this technical solution, Lenzing's high-count Modal fiber is selected as the raw material, and the resulting jersey fabric has a refreshing feel, is delicate against the skin, is silky and comfortable, and has good wear resistance.

[0048] The weaving adopts the form of plain weave knitting. By improving the padding equipment and process, the fabric blank is stretched in a different direction than the conveying direction during the padding process. This makes the fabric blank form a stretching effect in the padding tank 1 that is different from the conveying direction. Before the padding process, the fabric blank can be split along the weft knitting longitudinal direction or the weft knitting transverse direction as needed, so that it can form a continuous fabric blank structure according to the different extensibility of plain weave knitted fabrics. Then, the stretching component forms a stretching effect in a different direction than the conveying direction to ensure that the cool silicone oil is evenly adhered during the padding process. The resulting product has excellent fineness and is cool and comfortable.

[0049] Example 2

[0050] refer to Figure 3 , Figure 4 Compared to Embodiment 1, the stretching assembly includes a stretching wheel 4 mounted on the frame. The stretching wheel 4 is connected to a matching motor that drives its rotation, and its rotation direction is consistent with the conveying direction of the fabric blank. The stretching wheel 4 is immersed in the padding tank 1, and the diameter of the stretching wheel 4 gradually decreases from its center to both sides. After the stretching wheel 4 contacts the upper surface of the fabric blank, its rotation causes the fabric blank to tend to extend outward from the center, achieving a similar effect to the stretching roller group 2 in Embodiment 1. Furthermore, the surface of the stretching wheel 4 is provided with raised textures 41 to increase traction. Unlike the stretching roller group 2, the stretching wheel 4 is located at the center of the fabric blank and extends below the conveying plane, causing slight deformation of the fabric blank to further improve the stretching effect.

[0051] Structurally, the stretching wheel 4 has a short shaft end 4a and a long shaft end 4b with inconsistent axial heights, with the axial height gradually increasing from the short shaft end 4a to the long shaft end 4b. As the stretching wheel 4 rotates, when the short shaft end 4a contacts the fabric blank, the stretching surface of the fabric blank shrinks. As the stretching wheel 4 continues to rotate, this stretching surface gradually expands, creating a cyclical stretching effect. This not only avoids excessive stretching of the fabric blank but also creates a staged stretching effect within the padding tank 1, thereby improving the padding effect.

[0052] The aforementioned materials, such as ice-feeling silicone oil and penetrant, can all be purchased commercially, and will not be elaborated upon here.

[0053] Although the invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the invention without departing from the spirit and scope of the invention as defined in the appended claims, all of which shall be within the scope of protection of the invention.
