Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a bamboo fiber fabric and a production method thereof. Background Art

[0002] Bamboo fiber is a magical transformation of natural bamboo. It is not ordinary bamboo pulp fiber, but cellulose fiber extracted from naturally grown bamboo. Pure bamboo fiber fabric has good air permeability, instant water absorption, wear resistance and dyeability. What's more amazing is that it also has natural antibacterial, antibacterial, mite removal, deodorization and UV resistance functions.

[0003] The excellent antibacterial properties of bamboo fiber come from the antibacterial and antibacterial substance "bamboo quinone" on the fiber cell wall, which has an inhibitory effect on Escherichia coli and thus has a health-care effect on the human body. Through high-tech processing, bamboo fiber retains strong antibacterial and antibacterial properties. Under the same conditions, bacteria can survive and multiply in cotton and wood fiber products, but not only can they not survive for a long time in bamboo fiber, but they can also disappear or decrease in a short time.

[0004] Bamboo fiber contains sodium copper chlorophyllin, which makes it have good deodorizing properties, and its deodorizing effect on acid odor and ammonia is much better than cotton cloth. At the same time, sodium copper chlorophyllin is also a safe and excellent ultraviolet absorber. Compared with hemp, cotton and other textiles, bamboo fiber fabrics can reduce the harm of ultraviolet rays to the human body to a certain extent.

[0005] Most bamboo fiber fabrics on the market are made of "bamboo pulp fiber", which is made by chemically dissolving bamboo into a viscous bamboo pulp and then spinning it.

[0038]

[0039] In the reeding process, the warp yarn is reeded, and the reed No. 111.33 is used. The reed is reeded in the order of heald No. 110*3+105*2+113*2. The ground heald threading method is 1.2.3.4.5., 3 insertions, and the side heald threading method is 29 reed side 4 insertions, left (6.7.6.7)*2+(66.77)*25+1.3.5.2.4.1.3.5, right 1.3.5.2.4.1.3.5.+(66.77)*24+(6.7.6.7)*3, reed width 330, drop wire 1.2.3.4.5.6., isolation heald 1.6.2.7., machine model ZAX-9100-340, reserved waste edge 1.2.3.4.5.1.3.5 (retain 1 heald for each), start from the right side and thread normally.

[0041] The matters needing attention during the production process are as follows:

[0042] Warping process:

[0043] The key to the warping process is to ensure that the tension, arrangement and winding are uniform. The tension configuration adopts the segmented method, and the side yarn is appropriately weighted. Take the following measures and requirements:

[0044] 1. Tension control: The tension is configured to be relatively small to reduce the strength loss of the yarn. The tension is configured in front, middle and back sections. The edge tension is 2 grams higher than the front area, and the conductive yarn tension is increased by 2 grams.

[0045] 2. The vehicle speed should be controlled at a low speed of 450 m / min. The speed must be stable to reduce elongation and breakage;

[0046] 3. Equipment requirements: ① The yarn guide of the warping creel should correspond to the position of the tension frame, and the tension frames should be aligned in the same row and column; ② The yarn channel, yarn guide eye, yarn guide porcelain nozzle, and head rollers should be free of damage and burrs to prevent the yarn from regenerating hairiness and hanging during the warping passage; ③ The height of the creel bracket should be straight and aligned;

[0047] 4. Operation requirements ① Before starting, all yarn channels and machine heads must be thoroughly cleaned. Clean them in time during the operation to prevent flower accumulation everywhere and prevent flying flowers from being attached; flower accumulation on the telescopic reed should be cleaned at any time, and flower accumulation under the yarn surface in the telescopic reed should be cleaned once for each axis. ② During the operation, make a timely inspection to observe whether the rotation of each tension disk is flexible and whether it has fallen off; ③ 5 meters before starting, strictly align the two sides to avoid sparseness or folding. ④ In terms of operation, "evenly growing the ends, accurately finding the ends, smoothly sorting the ends, and firmly joining the ends" should be achieved to eliminate twisted ends and broken ends and improve the quality of the warp beam.

[0048] Sizing process:

[0049] Process: Light sizing on the strands, only one bag of starch is used for sizing, no other sizing agents or additives are used, and waxing is not allowed.

[0050] Mixing the pulp: Use one bag of starch to fill the mixing barrel. Do not use back pulp.

[0051] Sizing rate: The grouting force should be large, and the sizing rate is not a concern.

[0052] Operation: The conductive wire is on the top to facilitate the arrangement of the warp yarns. The twisted wire is passed between the two warp yarns. The two warp yarns must be arranged evenly when sizing and reeding.

[0053] Reeding process:

[0054] 1. During the reeding process, the yarn must be straightened and the quality must be checked in time to prevent wrong threading and twisting.

[0055] 2. The healds, reeds, and blades must be smooth and free of damage and burrs.

[0056] 3. Operation requirements: The warp yarn is a different warp product, the conductive yarn is very thin, the color is light, and it is difficult to distinguish. When operating, pay attention to first separate the two yarns and tape them well.

[0057] 4. The Weaving Technology Department studies the reeding process and issues a new reeding process for production.

[0058] Weaving process:

[0059] (I) Process technology a. Adopting the process configuration of "high tension, medium opening, high back beam", the warp tension is controlled to be relatively large.

[0060] (II) Equipment:

[0061] 1. Cloth channel: The side supports should operate flexibly, and the waste threads, flying flowers and debris on the take-up roller and the cloth pressing roller should be cleaned up.

[0062] 2. Weft yarn channel: The weft storage device must be cleaned.

[0063] (III) Operation ① Clean the weft storage device and weft yarn channel to reduce the accumulation of weft fibers in this area. ② The weft stopper should make a timely inspection to deal with various yarn hairiness and flying fibers in time. ③ Three warp yarns should be inserted into a reed with conductive yarn to prevent the conductive yarn from being exposed. The weft stopper should strictly check the reed for errors.

[0064] Fabric inspection, fabric marking and fabric repairing processes:

[0065] According to GB / T406-2008 standard, the fabric is woven according to the dyed blank standard, and the fabric surface is mainly weft shrinkage.

[0066] Comparative Example 1

[0067] The fabric of this comparative example is produced according to the method of Example 1, except that the warp yarn and weft yarn are both composed of 50% pure bamboo fiber 60S compact yarn.

[0068] Comparative Example 2

[0069] The fabric of this comparative example is produced according to the method of Example 1, except that the warp yarns and weft yarns are both composed of bamboo pulp fiber 60S compact.

[0070] The tensile strength and air permeability tests were performed on Example 1, Comparative Example 2, and the test results are shown in Table 2 below.

[0071] Table 2

[0072] Tensile strength(MPa) <![CDATA[Air permeability m 3 / (m 2 ·h)]]> Example 1 1215 445 Example 2 822 391 Example 3 761 339

[0073] It can be seen from Table 2 that the tensile strength and air permeability tests of the 100% pure bamboo fiber raw material prepared by the present invention are significantly better than those of general bamboo fiber and bamboo pulp fiber fabrics.

[0074] The present invention relates to a pure bamboo fiber fabric and a production method thereof. Pure bamboo fiber is a magical transformation of natural bamboo. It is a cellulose fiber extracted from naturally grown bamboo. It is the fifth largest natural fiber after cotton, linen, wool and silk. It has excellent properties such as high strength, good rigidity, renewability and degradability. Therefore, pure bamboo fiber fabric is a new natural biological environmentally friendly material with the characteristics of natural antibacterial, good air permeability, softness and comfort. It is widely used in clothing, home furnishing, medical treatment and other fields. With the improvement of people's environmental awareness, pure bamboo fiber fabric will receive more and more attention and popularity, and be used to weave healthier and more comfortable textiles.
