[0042] In order to better understand the present invention, the present invention is described in detail below in conjunction with specific embodiments.

[0043] Example 1

[0044] like Figure 1 As shown, an island-type ultrafine fiber fabric includes a fabric body, which is made of raw materials by warp knitting according to corresponding tissues, and the raw materials include an island-type ultrafine fiber 1 with a mixing ratio of 5-45%, a DTY (Draw texturing yarn) synthetic fiber 2 with a mixing ratio of 5-45%, and a FDY (FULLY DRAWNYARN) synthetic fiber 3 with a mixing ratio of 10-90%, wherein the island-type ultrafine fiber 1 and the DTY synthetic fiber 2 are arranged at intervals and float on the FDY synthetic fiber 3 in a coil shape.

[0045] It should be noted that in the process of weaving the raw materials into the fabric body according to the corresponding organization, the threading method is: each warp or weft thread only passes through one knitting needle, leaving a "pocket" or "basket" at the next knitting needle position, thereby forming a diamond-like structure. In the structure formed by this threading method, each weft thread is interlaced with the adjacent warp thread in the transverse direction, thereby forming a very tight and firm woven structure, which makes the fabric have very good strength and ductility.

[0046] The single fiber diameter of the island-in-sea type ultrafine fiber is 10-2000nm, the DPF is 0.1-7DPF, and the fiber thickness is 20-200D; the single fiber diameter of the DTY synthetic fiber is 4000-20000nm, the DPF is 0.05-7DPF, and the fiber thickness is 20-150D.

The gram weight of the fabric body is 50-250g / m 2 The warp density of the fabric body is 20-60 threads / inch, and the weft density is 20-80 threads / inch.

[0047] It should be noted that the sea-island type microfibers have high tensile strength and modulus, which can effectively improve the strength and hardness of the fabric. DTY synthetic fibers and FDY synthetic fibers have good softness and elasticity, which can make the fabric softer and more comfortable. By using sea-island type microfibers, DTY synthetic fibers and FDY synthetic fibers to weave the fabric body, a fabric body with good strength, softness and elasticity can be obtained.

[0048] It should be further explained that the fiber twist of the island-type microfiber, DTY synthetic fiber and FDY synthetic fiber can be twisted or untwisted, the fiber luster can be any combination of glossy, semi-glossy, matte, etc., and the fiber cross-section can be round or special-shaped.

[0049] The performance test of the island-in-sea type ultrafine fiber fabric showed that its dynamic friction force was 0.3-3N and its static friction force was 0.5-3N.

[0078] Example 2

[0079] This embodiment provides a method for preparing the sea-island type microfiber fabric described in the above embodiments. Figure 3 As shown, including:

[0080] Step 1: knitting the sea-island type ultrafine fiber, DTY synthetic fiber and FDY synthetic fiber according to the corresponding organization to obtain a grey cloth;

[0081] Step 2: performing a fiber opening treatment on the grey cloth to dissolve the sea component in the sea-island type ultrafine fiber to obtain sea-island type ultrafine fiber including only the island component and having a single fiber diameter of 10-2000 nm;

[0082] Step 3: Dyeing the grey fabric after fiber opening;

[0083] Step 4: Post-forming the dyed grey fabric;

[0084] Step 5: Inspect the grey cloth after post-setting treatment to obtain the sea-island type microfiber fabric body.

[0085] In step 1, the corresponding organizations include:

[0086] The sea-island type ultrafine fiber is threaded alternately through the No. 1 and No. X1 needle tracks every 46 needles for every 10 needles in the warp direction; and is threaded alternately through the No. 1 and No. X1 needle tracks every 46 needles for every 10 needles in the weft direction;

[0087] The DTY synthetic fiber is alternately threaded through the No. 1 and No. X1 needle tracks every 46 needles for every 10 needles in the warp direction; and is alternately threaded through the No. 1 and No. X1 needle tracks every 46 needles for every 10 needles in the weft direction;

[0088] The FDY synthetic fiber is alternately threaded through the No. 1 and No. X1 needle tracks every 22 needles for every 10 needles in the warp direction; and is alternately threaded through the No. 1 and No. X1 needle tracks every 9 needles for every 1 needle in the weft direction.

[0089] In simple terms, the weave diagram of the raw material FDY synthetic fiber in the warp direction is 10 / 23, and the threading is O1X1; the weft direction is 01 / 10, and the threading is O1X1; the weave diagram of the raw material DTY synthetic fiber in both the warp and weft directions is 10 / 56, and the threading is O1X1; the weave diagram of the raw material sea-island type microfiber in both the warp and weft directions is 10 / 56, and the threading is O1X1. Through this weave structure of the fabric body, the surface of the fabric body has a convex structure, thereby increasing the dynamic and static friction coefficients of the fabric body and improving the anti-slip effect of the fabric body.

[0090] In step 2, the grey cloth is subjected to a reduction and fiber opening treatment to dissolve the sea component in the island-type microfibers, including: placing the grey cloth in warm water at 60-100°C for 40-60 minutes, adding 25-35g / l of sodium hydroxide for alkaline treatment to dissolve the sea component in the island-type microfibers.

[0091] After the fiber opening treatment in step 2, the "sea" component in the island-in-sea type ultrafine fiber 1 is dissolved, leaving the "island" component, such as Figure 2 As shown, the island-type ultrafine fiber 1 is transformed into a nano-scale ultrafine fiber, and the ultrafine fiber has a small single filament fineness, a large fiber specific surface area, and the gaps between the fibers produce a wicking effect, so it has a strong moisture absorption capacity. After the fiber absorbs moisture and expands, the ultrafine fiber has a large contact surface area and can provide more friction contact points, further improving the friction of the fabric body and achieving an anti-slip effect.

[0092] In step 3, the opened grey cloth is dyed, including: placing the opened grey cloth in a dye solution at 130-135° C. and dyeing for 30 minutes; adding ethyl methacrylate polymer to the dye solution, wherein the added amount of ethyl methacrylate polymer is 0.2-2.5% of the grey cloth.

[0093] Through step 3, the obtained fabric body has a good dyeing effect; adding ethyl methacrylate polymer in the dyeing process can promote the dispersion of dyes, maintain uniform concentration and prevent pollution and color mixing in the dye solution.

[0094] In step 4, the dyed grey cloth is subjected to post-setting treatment, including: heating the dyed grey cloth at 160-180° C. for 20-30 minutes, and spraying setting liquid on the grey cloth during the heating process; ethyl cellulose and silicone oil additives are added to the setting liquid, wherein the amount of silicone oil additives added is 0.5-2.5% of the grey cloth; the silicone oil additives include the following raw materials: 40-60 parts of low molecular weight silicone oil, 5-10 parts of ethyl cellulose, and 30-40 parts of deionized water.

[0095] Through step 4, the obtained fabric body can have good dimensional stability and shape memory; adding silicone oil additives during the post-setting process can enhance the softness and smoothness of the fabric and improve the hand comfort; adding ethyl fiber to the silicone oil additives can help lubricate and arrange the fibers in the fabric, thereby enhancing the bonding between the fibers and improving the overall strength and wear resistance of the fabric.

[0096] Example 3

[0097] This embodiment provides an application of the island-in-sea type microfiber fabric in the aforementioned embodiment, including: the island-in-sea type microfiber fabric is used for the surface of an anti-slip product, and the anti-slip product includes at least one of bedding, car mats, sofas, carpets, insoles, and Velcro.

[0098] Example 4

[0099] This embodiment describes in detail the use of the island-in-sea microfiber fabric on the surface of bedding. The bedding includes a quilt core, a mattress core, a pillow core, etc. The bedding is used with a bedding cover, and even if no fixing facilities are provided between the bedding and the bedding cover, the bedding can be prevented from being significantly displaced in the bedding cover. Corresponding to bedding such as a quilt core, a mattress core, and a pillow core, the bedding cover includes a quilt cover, a mattress cover / mattress sheet / bed cover, a pillowcase, etc.

[0100] The bedding coat is made of a fabric woven from silk threads with a total fineness of 36 to 100 dtex and an F number of 90 or more, and the silk threads are false twisted and shrunk threads; the covering factor CF of the fabric used to make the bedding coat is 1200 or more; the fabric used to make the bedding coat is subjected to sweat absorption processing and gloss processing.

[0101] Taking the use of the sea-island type microfiber fabric on the surface of a quilt as an example, the method of using it is described.

[0102] The sea-island type microfiber fabric is cut into certain shapes, such as strips, circles, triangles, polygons, etc., and the cut sea-island type microfiber fabric is fixed to the surface of the quilt core by sewing, pasting or other methods, such as the four corners of the quilt core, or the two sides of the quilt core. Then the quilt core is set in the quilt cover.

[0103] The anti-slip performance of the sea-island type microfiber fabric when used on the surface of a quilt core was tested.

[0104] In the experiment, a total of 8 quilt cores of the same brand and model were used. The quilt cores were numbered 1 to 8, among which quilt cores No. 1 to 4 were matched with quilt covers made of the fabric for making bedding outer covers mentioned in this application (hereinafter referred to as comparison quilt covers); quilt cores No. 5 to 8 were matched with quilt covers of the same model of a certain brand on the market (hereinafter referred to as commercially available quilt covers). The surfaces of quilt cores No. 1 and No. 5 are not provided with the sea island type microfiber fabric in this application, while the four corner surfaces of quilt cores No. 2 to 4 and No. 6 to 8 are obliquely provided with the sea island type microfiber fabric 4 in this application cut into strips, as Figure 4 As shown; the specific parameters of the raw materials of the sea-island type microfiber fabric are shown in Table 1.

[0105] Table 1 Quilt core configuration table

[0106]

[0107] It should be noted that, for other parameters of the sea-island type microfiber fabric not described in Table 1, the quilt cores are consistent.

[0108] The specific experimental process is: mark the same position of the upper end (head side end) of the quilt core and quilt cover of each quilt, and then cover the quilt on a lying human model, whose knees can be controlled to bend and straighten. Control the human model's knees to bend to the maximum angle and then control them to straighten. After repeating 10 times, measure the position deviation of the marks on the quilt core and quilt cover and record them. For each quilt, repeat the above process five times, calculate the average value of the position deviation as the final position deviation. If the final position deviation is less than 5mm, it is recorded as ◎, between 5 and 8mm as 0, between 8 and 15mm as △, and above 15mm as □. After the experiment, the measurement results of the quilts composed of each quilt core are shown in Table 2.

[0109] Table 2 Final position deviation measurement results

[0110]

[0111]

[0112] It can be found from Table 2 that after the sea-island type microfiber fabric is used on the surface of the quilt core, the displacement between the quilt core and the quilt cover is significantly reduced. If the matching quilt cover is made of the fabric for preparing the bedding cover mentioned in the present application, the displacement between the quilt core and the quilt cover is more significantly reduced, almost equivalent to no displacement. Therefore, there is no need to use fixing facilities on the quilt core and the quilt cover, which provides a better user experience.

Although the above embodiments describe the present invention in detail, those skilled in the art should understand that they may modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents, and these replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present invention.
