Description

Technical Field

[0001] This invention relates to the field of wool-like fabric technology, specifically to a wool-like knitted fabric and its preparation method. Background Technology

[0002] Wool fabric is a type of fabric woven from wool. It is divided into woven fabric and knitted fabric. Due to the shrinkage problem of wool fabric, the most common alternative fabric on the market is imitation wool fabric. However, due to the knitting density of imitation wool fabric, the production efficiency of products made by simple knitting is relatively low, which in turn affects the company's profits. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this invention provides a wool-like knitted fabric and its preparation method, solving the problem of low efficiency in producing wool-like fabric products using only knitting processes.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a wool-like knitted fabric, wherein the wool-like knitted fabric is composed of a first weft, a second weft and a warp, the ends of the first weft and the second weft are sealed with warp, the first weft and the second weft are interlaced in a figure-eight shape and wrapped around the outside of the parallel warp, and the first weft and the second weft are provided with imitation cashmere directly above the warp;

[0007] The warp is made of a first cotton thread and a first polyester thread twisted together. The first weft and the second weft are both composed of a second polyester thread, a linen thread and a second cotton thread arranged in parallel. The linen thread is distributed on the lower side between the second polyester thread and the second cotton thread. The imitation cashmere passes between the second polyester thread and the second cotton thread, and its lower end is spaced apart on both sides of the linen thread. The ratio of the length of the imitation cashmere above the second polyester thread and the second cotton thread to the length of the imitation cashmere below the linen thread is 10:1.

[0008] Preferably, the imitation cashmere distributed on each of the weft threads is a group and the distribution length is one-third of the diameter of the weft thread. The spacing between the imitation cashmere threads is 0.5 mm, and the minimum distance between the distribution gaps of adjacent warp threads is 0.2-0.3 times the diameter of the warp thread.

[0009] A method for preparing a wool-like knitted fabric includes the following preparation steps:

[0010] Step 1: Antibacterial treatment

[0011] The first cotton thread, the second cotton thread, and the flax thread were soaked in a solution of organosilicon antibacterial agent and water at a weight ratio of 1:25 for 1-2 days.

[0012] Step 2: Twisting the warp threads

[0013] The first cotton thread and the first polyester thread obtained in step one are twisted together and wound into a roll for later use;

[0014] Step 3: Soak the adhesive

[0015] The warp yarn obtained in step two is inserted into the 80°C gum arabic adhesive from one end, and after drying, it is rewound. Two-fifths of the height of one end of the imitation cashmere is immersed in the 80°C gum arabic adhesive. Then, the imitation cashmere is arranged in an array with a distribution spacing of 0.5mm x 0.5mm on the side of the imitation cashmere immersed in the gum arabic adhesive.

[0016] Step 4: Preparing the weft threads

[0017] The second polyester thread, linen thread, and second cotton thread are arranged in parallel, with the linen thread positioned below the middle of the second polyester thread and the second cotton thread. Then, one end of the imitation cashmere, soaked in peach gum water-soluble adhesive, is sandwiched between the second polyester thread and the second cotton thread, and is staggered on both sides of the linen thread at the lower end, so that the ratio of the length of the imitation cashmere above the second polyester thread and the second cotton thread to the length of the imitation cashmere below the linen thread is 10:1. The imitation cashmere is arranged in groups at equal intervals on the second polyester thread, the linen thread, and the second cotton thread, thus forming the weft thread.

[0018] Step 5: Shaping

[0019] The weft yarns are placed with the portion of the imitation cashmere soaked in peach gum water-soluble adhesive facing downwards. One group of imitation cashmere on one weft yarn is positioned in the middle of the two adjacent groups of imitation cashmere on another weft yarn and arranged in parallel. Then, the spaced weft yarns are divided into two groups, and the warp yarns are inserted after the two groups of weft yarns are swapped. This process is repeated. The ends of the weft yarns are knitted with warp yarns for edge sealing, and the ends of the warp yarns are knitted with weft yarns for edge sealing to obtain the imitation wool knitted fabric blank. The width of the edge sealing is 5cm.

[0020] Step Six: Water Immersion

[0021] The imitation wool knitted fabric blank prepared in step five is soaked in water with added soda ash at 65℃ for 15-20 minutes, and the imitation wool knitted fabric blank is turned over 2-3 times during the process.

[0022] Step 7: Staining

[0023] Add the wool-like knitted fabric blank treated in step six to the dyeing bath, and run it at 95-100℃ for 30-35 minutes with the temperature increased at 3-4℃ / min.

[0024] Step 8: Cleaning

[0025] The imitation wool knitted fabric blank obtained in step seven is treated with a color-fixing agent and then washed with soap.

[0026] Step 9: Drying

[0027] The wool-like knitted fabric blank obtained in step eight is dried at a temperature of 80-85℃ using a vibration drying method.

[0028] Preferably, the imitation wool knitted fabric blank obtained in step nine is subjected to a napping process, a shearing process, and an opening and shaping process to obtain the finished imitation wool knitted fabric.

[0029] (III) Beneficial Effects

[0030] This invention provides a wool-like knitted fabric and its preparation method. It has the following beneficial effects:

[0031] In this invention, the weft and warp yarns are bonded together using a peach gum water-soluble adhesive for weaving, so that the imitation cashmere is located on one side of the finished product. The processing speed is faster than that of simple knitting. After edge sealing, the integrity of the product is improved, which can prevent the edges from opening. In addition, the overall product is fluffy, breathable, and has excellent wrinkle resistance and antibacterial properties. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example:

[0037] like Figure 1-2As shown, this embodiment of the invention provides a wool-like knitted fabric. The wool-like knitted fabric is composed of a first weft 1, a second weft 3, and warp yarns. The ends of the first weft 1 and the second weft 3 are sealed with warp yarns. The first weft 1 and the second weft 3 are interlaced in a figure-eight shape and wrapped around the outside of the parallel warp yarns. The first weft 1 and the second weft 3 are provided with imitation cashmere 2 directly above the warp yarns. That is, the side containing imitation cashmere 2 is the front side of the wool-like knitted fabric. The imitation cashmere 2 is made of acrylic fiber. The first weft 1 and the second weft 3 have the same structure.

[0038] The warp is made of a first cotton thread 4 and a first polyester thread 5 twisted together. The polyester gives the warp excellent elasticity. The first weft 1 and the second weft 3 are both composed of a second polyester thread 6, a linen thread 7 and a second cotton thread 8 arranged in parallel. The second polyester thread 6 provides excellent elasticity to the first weft 1 and the second weft 3. The linen thread 7 is distributed on the lower side between the second polyester thread 6 and the second cotton thread 8. The imitation cashmere 2 passes between the second polyester thread 6 and the second cotton thread 8, and its lower end is spaced on both sides of the linen thread 7. The ratio of the length of the imitation cashmere 2 on the upper side of the second polyester thread 6 and the second cotton thread 8 to the length of the imitation cashmere 2 below the linen thread 7 is 10:1.

[0039] The imitation cashmere 2 distributed on each weft thread is a group and the distribution length is one-third of the diameter of the weft thread. That is, the distribution range of several imitation cashmere 2 in a group is a straight line and the distribution length is one-third of the diameter of the weft thread. The spacing between the imitation cashmere 2 is 0.5mm. The minimum distance between the distribution gaps of adjacent warp threads is 0.2-0.3 times the diameter of the warp thread, so that the first weft thread 1 and the second weft thread 3 are woven more tightly between the warp threads.

[0040] A method for preparing a wool-like knitted fabric includes the following preparation steps:

[0041] Step 1: Antibacterial treatment

[0042] Soaking the first cotton thread 4, the second cotton thread 8, and the flax thread 7 in a solution of organosilicon antibacterial agent and water at a weight ratio of 1:25 for 1-2 days can improve the antibacterial properties of the first cotton thread 4, the second cotton thread 8, and the flax thread 7.

[0043] Step 2: Twisting the warp threads

[0044] The first cotton thread 4 and the first polyester thread 5 obtained in step one are twisted together and wound into a roll for later use. Winding the warp threads into a roll makes it easier to transfer the warp threads.

[0045] Step 3: Soak the adhesive

[0046] The warp yarn obtained in step two is inserted into the 80°C gum arabic adhesive from one end, and after drying, it is rewound. Two-fifths of the height of one end of the imitation cashmere 2 is immersed in the 80°C gum arabic adhesive. Then, the imitation cashmere 2 is arranged in an array with a distribution spacing of 0.5mm x 0.5mm from the side immersed in the gum arabic adhesive. The gum arabic adhesive is made by dissolving gum in water at 80°C. Immersing the imitation cashmere 2 in the gum arabic adhesive can increase the hardness of the immersed end, which facilitates the molding process in step five.

[0047] Step 4: Preparing the weft threads

[0048] The second polyester thread 6, linen thread 7, and second cotton thread 8 are arranged in parallel, with the linen thread 7 positioned below the middle of the second polyester thread 6 and the second cotton thread 8. Then, one end of the imitation cashmere 2, which has been soaked in gum arabic adhesive, is sandwiched between the second polyester thread 6 and the second cotton thread 8, and is staggered on both sides of the linen thread 7 at the lower end, so that the ratio of the length of the imitation cashmere 2 above the second polyester thread 6 and the second cotton thread 8 to the length of the imitation cashmere 2 below the linen thread 7 is 10:1. The imitation cashmere 2 is arranged in groups at equal intervals on the second polyester thread 6, the linen thread 7, and the second cotton thread 8, thus forming the weft yarn.

[0049] Step 5: Shaping

[0050] The weft yarns are arranged with the portion of the imitation cashmere 2 soaked in peach gum water-soluble adhesive facing downwards. One group of imitation cashmere 2 on one weft yarn is positioned in the middle of the two adjacent groups of imitation cashmere 2 on another weft yarn and arranged in parallel. Then, the warp yarns are divided into two groups, and the two groups of warp yarns are swapped and interlocked. This process is repeated. The ends of the weft yarns are knitted with warp yarns for edge sealing, and the ends of the warp yarns are knitted with weft yarns for edge sealing to obtain the imitation wool knitted fabric blank. The edge sealing width is 5cm. Edge sealing can improve the integrity of the finished imitation wool knitted fabric blank and prevent it from opening.

[0051] Step Six: Water Immersion

[0052] The imitation wool knitted fabric blank prepared in step five is soaked in water with added soda ash at 65°C for 15-20 minutes. During the process, the imitation wool knitted fabric blank is turned over 2-3 times. The water soaking treatment can dissolve the peach gum water-soluble adhesive on the imitation wool knitted fabric blank and allow a small amount of peach gum water-soluble adhesive to be absorbed into the cotton thread, which facilitates the combination of cotton thread with polyester thread, linen thread, and imitation cashmere, and can also make the cotton thread fluffier.

[0053] Step 7: Staining

[0054] Add the wool-like knitted fabric blank treated in step six to the dyeing bath, and run it at 95-100℃ for 30-35 minutes with the temperature increased at 3-4℃ / min.

[0055] Step 8: Cleaning

[0056] The imitation wool knitted fabric blank obtained in step seven is treated with a color-fixing agent and then washed with soap.

[0057] Step 9: Drying

[0058] The imitation wool knitted fabric blank obtained in step eight is dried at a temperature of 80-85℃ using a vibration drying method. After the imitation wool knitted fabric blank undergoes a napping process, a shearing process, and a width setting process, the finished imitation wool knitted fabric is obtained.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
