However, the existing clothing fabric cannot have good fluffiness and high elasticity simultaneously due to the imperfect production process, so that the requirement of people cannot be met.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides the multi-component vortex-spun bulked blended yarn and the production process thereof, various fibers are blended into the bulked yarn through vortex spinning, and the woven fabric is increased to 1-5 times than normal and has fluffy and wrinkled effects.
In order to achieve the purpose, the invention provides the following technical scheme: the multi-component vortex spun bulked blended yarn is formed by blending polyester staple fibers, polyamide staple fibers and other fibers, wherein the proportion of each fiber is 50% -65%, 25% -30% and 15% -20%, the thermal shrinkage rate of the polyester staple fibers is 20% -40%, and the thermal shrinkage rate of the polyamide staple fibers is 25% -35%.
By utilizing the heat shrinkage characteristic of the high-shrinkage polyester staple fiber, after heat treatment shrinkage, partial shrinkage is generated on the surface of the fabric, so that a wrinkle effect is formed. The nylon staple fiber also has potential shrinkage performance, and the shrinkage rate can be 20-35% through heat treatment. The resilience of the yarn is an important factor for wrinkling the fabric, the strong twisted yarn has high resilience, and the yarn is twisted and shrunk by utilizing the torsional deformation energy released in the fabric by the yarn in the fabric, so that the fabric is wrinkled. The most widely used polyester hard-twisted yarns comprise polyester low-stretch yarn hard-twisted yarns, different-shrinkage yarn hard-twisted yarns and high-shrinkage yarn hard-twisted yarns.
Further, the other fibers adopt one or more of common dyed staple fibers, colored sliced staple fibers, natural color staple fibers or combed cotton.
Furthermore, the specification of the polyester staple fiber is 1.33 dtex multiplied by 38mm, and the specification of the nylon staple fiber is 1.67dtex multiplied by 38mm in length.
The production process of the multicomponent vortex spun bulk blended yarn comprises the following steps: fiber dyeing → cotton blending, cotton mixing → cotton opening → cotton carding → drawing → vortex spinning → heat treatment.
The fiber dyeing adopts fiber raw materials without oligomer, static electricity, oil agent or low oil agent; antistatic control is carried out when the fibers are mixed, and the mixed raw materials need to ensure no static electricity and low oil solution. After the high-shrinkage polyester staple fibers, the polyamide staple fibers and the low-shrinkage yarns are blended, the blended yarns are subjected to heat treatment, the high-shrinkage fibers after the heat treatment are shrunk into core yarns by utilizing the difference of the heat shrinkability of the fibers, and the low-shrinkage fibers are extruded to form loops on the surfaces, so that the yarns are fluffy and soft and have lower retractility and higher fluffiness.
The cotton carding process follows the general principle of 'tight spacing, strong carding and easy transfer', the specific gravity of the chinlon is light, the handfeel is soft, the fluffiness is good, and the cotton carding strips are thick. In order to prevent the horn mouth from being blocked, light weight is adopted on the premise of ensuring the normal cotton net.
Further, an impurity removal process is added between opening and picking cotton, cotton blending and cotton mixing, and a continuous whipping device is adopted in the impurity removal process to remove impurities. The impurities after dyeing can not be removed by a simple water washing process, the raw materials are beaten by a continuous device, and dye particles condensed on the surface of the fiber are separated, so that the spinnability of the fiber is ensured, and the residual dye is prevented from polluting spinning equipment.
Further, drawing adopts three-pass drawing, the interval of head-roller combination is 11 × 8.5 × 18mm, the drafting multiple of the back zone is 1.61 times, the total drafting multiple is 6.74 times, and the number of drawing is 8; the interval between two parallel rollers is 11 × 8.5 × 18mm, the back zone drafting multiple is 1.45 times, the total drafting multiple is 8.05 times, and the number of the combined rollers is 8; the interval between the three rollers is 10 × 8.5 × 17mm, the drafting multiple of the back zone is 1.25 times, the drafting multiple of the total zone is 6.09 times, and the total number of the drafting is 6.
The drawing process is mainly used for improving the fiber straightness, improving the internal framework of the sliver and simultaneously considering the evenness of the sliver, and three-way combination is adopted to ensure the evenness of mixing. Combining the head and the second and improving the hook and the internal structure, and the third and improving the evenness mainly and considering the residual hook. Three kinds of fibre are mixed at the beginning soldier, choose for use great back zone draft and less total draft, improve the crotch in the raw sliver, secondly and adopt less back zone draft, the effect of full play total draft, the control action of back zone draft is less, thirdly and adopt littleer draft multiple, can effectively reduce the displacement deviation, help improving the ripe sliver evenness degree.
Further, in the vortex spinning process, the air pressure of a nozzle is 0.5-0.6MPa, the distance between a guide needle and a yarn withdrawal tube is 0.45-0.55mm, and the spinning speed is 370-400 m/mim. The air-jet vortex spinning cancels the procedures of roving, spinning and spooling of ring spinning, directly spins and produces cone yarn, realizes the integration of roving, spinning and spooling, saves the process flow, has full-automatic continuous production in the whole spinning process, can automatically control spinning by a single spindle, and has high production speed and high efficiency. The process parameters are adopted for vortex spinning, and the internal structure of the fiber is arranged loosely and disorderly, and has small twist, low strength and large resilience.
Further, the temperature of a workshop in the vortex spinning process is controlled to be 26-30 ℃, and the relative humidity is 50-65%. As the fibers are fluffy and are easy to generate static electricity, the temperature and the humidity of a workshop need to be well controlled, and the static electricity phenomenon is reduced.
