Description

Technical Field

[0001] This invention relates to the field of fabric technology, and in particular to a down-like fabric with good warmth retention and its applications. Background Technology

[0002] Existing materials used as substitutes for down, such as spray-bonded cotton, suffer from poor warmth retention and durability, are prone to clumping and tearing after washing, and cannot be dyed. Currently, they can only be used in the low-to-mid-range market. Furthermore, existing down substitutes are prone to shedding feathers and have low warmth retention, affecting the comfort of winter wear.

[0003] The high-end market is still dominated by down, but people's respect for animal rights and awareness of protection are increasing. The price of animal down is subject to large market fluctuations, which leads to an increase in the corresponding product cost. Moreover, animal down has always had problems such as clumping, slippage, and down leakage, which affect the consumer experience. Summary of the Invention

[0004] This invention provides a down-like fabric with good warmth retention. Its main purpose is to overcome the many product and service defects of existing alternative down materials and animal down, and fully reflect the advantages of high heat retention, lightness and easy care, which is in line with the current social clothing consumption trend - especially outdoor sports and leisure, alpine sports, ice and snow sports and outdoor camping.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a down-like fabric with good warmth retention, comprising a fabric body, wherein the fabric body is a four-way loop, and the four ways are all four-needle loops; wherein, the first yarn is woven into the first way, and the first way, the second way, the third way, and the fourth way are all woven in a loop manner.

[0006] Preferably, the first, second, third, and fourth lines are all knitted using a combination of looping needles on the upper needle plate and looping needles on the lower needle cylinder.

[0007] Preferably, the first yarn is a down-like yarn.

[0008] Preferably, the method for preparing the down-like yarn includes the following preparation steps:

[0009] Step 1: Place the fiber filaments on the twisting machine and start the twisting machine to twist the fiber filaments into a spiral semi-processed fiber yarn;

[0010] Step 2: Place the semi-processed fiber yarn into a steaming equipment for steaming and then air-dry it after stabilizing the spiral angle of the semi-processed fiber yarn.

[0011] Step 3: Take two semi-processed steamed fiber yarns after air drying and feed them into the CNC feeding rollers of a multi-channel twisting machine. Each semi-processed steamed fiber yarn is controlled by an independent CNC feeding roller. Entering the CNC twisting zone, the two semi-processed steamed fiber yarns take turns performing CNC programmed overfeeding, binding, and winding actions. After completing the above complex alternating overfeeding and winding into a retwisted yarn, a vertical loop retwisted yarn with the required height is formed. The vertical loop retwisted yarn enters the CNC pulling roller. While the feeding roller is performing CNC programmed actions, the pulling roller performs a coordinated CNC programmed pulling action. After exiting the pulling zone, the vertical loop retwisted yarn enters the synchronous winding.

[0012] Step 4: Take multiple looped retwisted yarns together and feed them into the yarn napping equipment in a continuous state. The yarn napping equipment continuously and evenly breaks the loop structure on the looped retwisted yarns to form fluffy yarns. At the same time, it can simultaneously take the yarns into strands.

[0013] Step 5: The spun down yarn is wound onto a precision winding machine and wound into bobbins at a constant length and tension. Waxing is performed simultaneously during the bobbin winding process to obtain down-like yarn.

[0014] Preferably, in step one, the material of the fiber filament is chemical fiber, regenerated cellulose fiber, biomass regenerated fiber, or natural fiber. Chemical fibers include polyester fiber, polypropylene fiber, polyethylene fiber, or nylon fiber. Regenerated cellulose fibers include viscose, modal, and Tencel. Biomass regenerated fibers are acetate fiber and polylactic acid fiber. Natural fibers include cotton, wool, silk, and linen fibers. The twisting machine rotates at a speed of 4000-8000 r / min, and the tension of the fiber filament is adjusted to 10-50 N.

[0015] Preferably, in step two, the steaming equipment is a steam vacuum dry steaming equipment, the controllable temperature of the steam vacuum dry steaming equipment is 50-150℃, and the steaming time is more than 30 minutes.

[0016] Preferably, in step two, a tunnel-type drying box is used to dry, cool, and relax the steamed fiber yarn. The tunnel-type drying box is equipped with an air outlet mechanism for circulating and blowing the steamed fiber yarn. The controllable temperature of the tunnel-type drying box is 24-200℃, and the wind speed is 0.3*(1±20%)m / s-6*(1±20%)m / s.

[0017] Based on the above, down-like fabrics with good warmth retention are used in clothing and home textiles.

[0018] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

[0019] This invention employs a four-way, one-loop weaving system, with the fabric structure using a combination of loop formation via upper needle discs and lower needle cylinders. This results in a robust fabric structure with strong loop uprightness, high loop compression resistance, good abrasion resistance, and high strength. Furthermore, the use of down-like yarn with excellent warmth retention significantly reduces the fabric's density compared to conventional thermal fabrics, resulting in superior warmth and enhanced wearing comfort.

[0024] The method for preparing down-like yarn includes the following steps:

[0025] Step 1: Place the fiber filaments on a twisting machine, adjust the twisting machine speed to 4000-8000 r / min, and adjust the tension of the fiber filaments to 10-50N. The twisting machine will twist the fiber filaments into a spiral semi-processed yarn. The fiber filaments are made of chemical fibers, regenerated cellulose fibers, or biomass regenerated fibers.

Set the controllable temperature of the steam vacuum dry scouring device to 50-150℃ and the steaming time to more than 30 minutes. After stabilizing the spiral angle of the steamed fiber yarn, place it back into the steam vacuum dry scouring device. Set the temperature of the steam vacuum dry scouring device to 24-200℃ and the wind speed to 0.3*(1±20%)m / s-6*(1±20%)m / s. Use the circulating hot air provided by the air outlet mechanism in the steam vacuum dry scouring device to circulate and blow the fiber yarn to ensure that the yarn is in a dry state.

[0027] Step 3: Take two semi-processed steamed fiber yarns after air drying and feed them into the CNC feeding rollers of a multi-channel twisting machine. Each semi-processed steamed fiber yarn is controlled by an independent CNC feeding roller. Entering the CNC twisting zone, the two semi-processed steamed fiber yarns take turns performing CNC programmed overfeeding, binding, and winding actions. After completing the above complex alternating overfeeding and winding into a retwisted yarn, a vertical loop retwisted yarn with the required height is formed. The vertical loop retwisted yarn enters the CNC pulling roller. While the feeding roller is performing CNC programmed actions, the pulling roller performs a coordinated CNC programmed pulling action. After exiting the pulling zone, the vertical loop retwisted yarn enters the synchronous winding.

[0028] Step 4: Take multiple looped retwisted yarns together and feed them into the yarn napping equipment in a continuous state. The yarn napping equipment continuously and evenly breaks the loop structure on the looped retwisted yarns to form fluffy yarns. At the same time, it can simultaneously take the yarns into strands.

[0029] Step 5: The spun down yarn is wound onto a precision winding machine and wound into bobbins at a constant length and tension. Waxing is performed simultaneously during the bobbin winding process to obtain down-like yarn.

[0030] This invention employs a four-way, one-loop weaving system, with the fabric structure using a combination of loop formation via upper needle discs and lower needle cylinders. This results in a robust fabric structure with strong loop uprightness, high loop compression resistance, good abrasion resistance, and high strength. Furthermore, the use of down-like yarn with excellent warmth retention significantly reduces the fabric's density compared to conventional thermal fabrics, resulting in superior warmth and enhanced wearing comfort.
