Then, the invention adopts the compact spinning technology, and improves the sizing efficiency by adjusting the spooling speed and the spooling density.
Finally, the yarn count of the fabric is 80S, and the fabric is endowed with fine hand feeling. The weave is designed into five three-flying satin, so that the glossiness and the surface effect of the fabric are improved.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained below.
The process names from the fiber to the fabric are as follows from front to back: fibril, a cotton cleaning process, a cotton carding process, a combing process, a drawing process, a roving process, a spinning process, spooling, doubling, twisting, spooling, warping, slashing, drawing in and weaving.
The preparation method of the lyocell fiber blended fabric comprises the following steps: step one, selecting 1.45dtex multiplied by 38mm lyocell fiber and 1.45dtex multiplied by 38mm cotton fiber, and carrying out compact spinning on the lyocell fiber and the cotton fiber according to the proportion of 50/50 to obtain blended yarns. The thickness of the fibers affects the surface area, and the finer the fibers, the greater the accessibility of the continuous medium and the more moisture the individual fibers become available for absorption and desorption. The invention selects the fineness of the fiber, firstly, the fabric obtained under the fiber fineness of the invention has soft hand feeling, and in addition, the fineness of the cotton fiber and the lyocell fiber of the invention keeps consistent, thus greatly improving the uniformity of spinning. And step two, weaving the fabric according to the specification that the warp yarns and the weft yarns are all 80S and the density ratio of the warp yarns to the weft yarns is 3:2, wherein the warp yarns and the weft yarns are the blended yarns obtained in the step one.
In the first step, in the cotton picking process, the speed of the bale plucker is set to be 1000r/min so as to ensure more times and less grabbing amount. The small grabbing amount can remove impurities carried by the fibers in the grabbed fibers every time, remove short fibers, ensure that the fibers do not increase the integral fineness and increase the point contact area due to the fact that the fibers carry the short fibers or the impurities, and further become rigid; the frequency is more in order to guarantee efficiency, improves whole cotton picking process efficiency. Thereby improving the rigidity of the lyocell fiber and reducing the occurrence of short fibers.
The carding needle of the fine cotton opener is passivated, and the end part of the carding needle is fixed with an end cap. The end cap is preferably football shaped. The center of end cap is equipped with the trompil, and after the tip of broach inserted the trompil, remaining space was full of the viscose in the trompil to it is fixed with the end cover through the viscose. The end cap is preferably football-shaped, so that the end cap has two symmetrical end faces up and down, on one hand, when the comb is installed, a user does not need to judge the upper end and the lower end, and the end of the comb needle is directly inserted into the open hole, on the other hand, after one end is worn, the end cap can be taken down and turned upside down, and then the comb needle is connected, so that the comb needle can be used for a second time. Finally, the rugby-shaped structure can avoid the comb needle from scratching the fibers and avoid excessive fiber striking. The comb is preferably made of metal. The adhesive is preferably a hot melt adhesive. When the end cap needs to be replaced, the comb pins are heated, heat is transferred to the viscose by the comb pins, the viscose is melted, and the end cap is removed. Thereby facilitating replacement of the end cap.
In order to further prevent the excessive striking to the fiber, the beater speed of the fine cotton opener is 300 r/min. In the carding process, the cylinder card clothing gauge is increased, the light gauge is achieved, and the carding quality is improved by repeatedly carding for many times. The cotton carding ration is 20g/5m, the licker-in speed is 800r/min, the cylinder speed is 350r/min, the space between the licker-in and the cylinder is 0.2mm, and the space between the cylinder and the doffer is 0.15 mm. The roller speed in the roving process is 250r/min, and the cradle pressure is 200-250N.
Further, the present invention spins by compact spinning. The integrated spinning is that an integrated device is added in front of a drafting device of a ring spinning frame to create a fiber integrated area, and fiber bundles migrating from a front roller jaw of the drafting device are integrated on a line, so that a spinning twisting triangular area between a front roller and a twisting point is basically eliminated. The integrated spinning effectively reduces the resultant yarn hairiness by better controlling the hairiness in the spinning twisting triangular area, reduces the friction degree of the yarn and the machine part by coating wax on the winding channel, and leads the loading tension to be more uniform and stable by adopting mechanical pressurization. The winding speed is set to 1100m/min, the winding density is controlled below 1g/cm3, and the electronic yarn clearer is short and thick and has a length of + 150% multiplied by 2cm and a length of + 50% multiplied by 20 cm. In the production process, the winding tension is mainly controlled by adjusting the technological parameters of a tension device, mechanical pressurization such as pneumatic pressurization of a double-tension disc endows the yarn with certain tension, the tension of the yarn is influenced by the air pressure, namely the change of loading pressure is caused, and the loading tension influences whether the bobbin is well formed or not.
In the warping process, the spooling speed is about 1100m/m, so that broken ends are reduced on the basis of ensuring the speed, and hairiness caused by overlarge speed and overlarge tension is avoided. Experiments show that when the winding speed is higher than 1200m/min, the winding tension is increased, so that the yarn breakage frequency is increased. The double-dipping and double-pressing sizing mode is adopted, the yarns are completely immersed into the size through the immersion roller, then the size is enabled to better permeate into the yarns through the tightly connected sizing roller, the process is a one-time dipping and pressing process, and the double-dipping and double-pressing process is that the yarns are subjected to twice dipping and twice sizing pressing processes, so that the sizing efficiency is improved. The fiber straightness is good in the integrated spinning, the structure is compact, and in order to ensure a good sizing effect, the slurry should be high in concentration and low in viscosity to enhance the fluidity of the slurry, so that the slurry is beneficial to soaking.
In the second step, the weave is designed into five three-flying satin weaves, an air jet loom is adopted, the speed of the loom is 450r/min, the air pressure is set to be 0.4-0.6 MPa, and the machine tension is 2800N.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
