Description

Technical Field

[0001] The invention belongs to the field of textiles, and in particular relates to a camel hair and stretch yarn composite flake and a preparation method thereof. Background Art

[0002] With the continuous maturity of textile production technology and application technology, several major categories of natural fiber textiles such as wool, cotton, silk, linen, and cashmere are becoming more and more popular among consumers, especially camel hair products, which are unique among various natural fiber products with their unique elegant appearance, softness and strong warmth retention. The demand is also increasing year by year. Under this background, the company has developed camel hair and comfortable stretch silk composite flakes. Summary of the invention

[0003] The invention provides a camel hair and stretch silk composite floccules, which is thin, soft, fluffy and warm. To this end, the invention also provides a preparation method of the camel hair and stretch silk composite floccules.

[0004] The invention provides a camel hair and stretch yarn composite flocculus, wherein the flocculus consists of 60% by mass of camel hair and 40% by mass of stretch yarn.

[0005] The present invention also provides a method for preparing the camel hair and stretch yarn composite flakes as described above, the steps being as follows: 1. It is suitable for fully mixing the two types of loose fibers and evenly conveying them to the next process. Photoelectric control of the amount of down in the down box. Protective plates are set at both ends of the down box to prevent the down from winding around the ends. The vibration plate can evenly adjust the speed to control the amount of down. The down box uses a corner curtain to convey the down to the next process.

[0006] 2. High-speed fine combing of various fibers into a mesh shape. The amount of down fed by the down feeder is fed into the rollers, and then sent to the next process through the licker-in roller, cylinder, and doffer. The doffer cylinder and the working roller stripping roller are all quenched and tempered. The card clothing uses the gold wheel card clothing, and the 4 75mm metal card clothings are wrapped and paired in two groups, upper and lower. The bearing seat and transmission gear of the first pair of upper rollers for feeding are nylon parts, which can be metal detected, and have a reverse function and automatic stop alarm. The quality of the combed fiber is 2 levels higher than that of the raw material, and the loss in the process is 4.5%. The roller input and the doffer output are both frequency-controlled, which can be adjusted in time through indicators.

[0007] .3. The control requirements for combing distance are: the distance between the large cylinder and the working roller and doffer plays a decisive role in the combing efficiency. (Note: the distance between the cylinder → doffer is 12S, the distance between the cylinder → working roller is 21S.) For the distance between the five working rollers on the cylinder, it should be gradually reduced from the first to the fifth working roller, (Note: the distance between working roller 1 → working roller 2 → working roller 3 → working roller 4 → working roller 5 is 22S, 19S, 17S, 15S, 12S in sequence). This is beneficial to the strengthening of the combing effect and can reduce the damage to the fiber. The distance between the cylinder and the doffer should also be relatively small. The combing speed ratio requirement is: when the speed of the large cylinder is constant, changing the speed of the working roller or doffer can change their speed ratio. Working roller speed: 680 rpm, doffer speed: 35 rpm. The larger the speed ratio, the greater the relative movement speed of the two needle surfaces. The longer the action area of ​​the working roller or doffer surface and the large cylinder surface per unit time, the more fibers are combed, thereby enhancing the combing efficiency. The speed ratio should take into account the size of the feed load and the mixing state.

[0008] 4. Cylinder speed: In the carding machine, the speed of the cylinder is very important. The cylinder speed is 380 rpm. It directly affects the output, the speed of other parts and the carding effect.

[0009] .5. Spread the combed fiber flocs into flocs of a certain thickness for the next process. Add non-woven fabrics in advance. After combing, the fibers are brought in by the transmission curtain and oblique curtain of the web laying machine, and then swung back and forth repeatedly through the middle curtain and the ring curtain and spread on the input curtain, and then input to the next process from the input curtain. The main structure of the web laying machine is composed of horizontal steel, which is thick enough to avoid vibration during operation. The web laying machine is equipped with a segmented stroke independent frequency conversion control to ensure the quality and flatness of the fiber web. Input curtain width: 1800mm. The width of the web flocs that can be laid is 1600mm. 6. Feed the input curtain flocculent web into the upper and lower stripping spindles, and use the upper and lower needle punching plates to repeatedly penetrate the fiber web at high speed in the vertical direction of the flocculent fiber web, so that most of the fibers are tied into fiber bundles, and the fibers are irregularly tightened to make the flocculent sheet as a whole into a finished flocculent sheet. The fiber flocculent sheet can be produced with a gram weight of 70-500g / ㎡. After testing, the surface of the flocculent sheet with a weight below 70g / ㎡ is uneven and transparent in some areas. The flocculent sheet with a weight above 500g / ㎡ will have some broken needles due to the resistance of the velvet product, and the broken needles will produce uneven floccules.

[0010] 7. Used for rolling up flakes after needling. Three cylinder cutters are used for longitudinal cutting, and flying cutters are used for cross-cutting. The roll is formed with a conveying curtain ring. When the set number of meters is reached, it is automatically cut.

[0011] The invention reduces the raw material consumption to the maximum extent, improves the product quality and realizes the production of the composite flakes of camel hair and stretch yarn by optimizing the production process, transforming the equipment mechanism and reasonably matching the camel hair raw materials.

[0012] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
