Description
Technical Field
The invention relates to the technical field of yarn manufacturing, in particular to a production method of hemp blended woven fabric.
Background
Although chemical fibers are widely used as the fabric of clothes, cotton fibers, hemp fibers, wool fibers and silk fibers are still favored by most consumers as the traditional natural fibers. However, in any fiber, the pure spinning product has certain defects. For example, although linen fabrics have excellent moisture absorption and ventilation, antibacterial and health care, ultraviolet protection and other performances, the spinning and weaving of linen fabrics are difficult due to the defects of high fiber rigidity, low elasticity and the like. Therefore, the blended yarn of the fibrilia, the viscose and the spun silk is selected as the raw material, the complementary advantages of the yarn performance are realized, and the high-efficiency production of the woven fabric of the fibrilia is realized through the optimization of the weaving process.
Disclosure of Invention
Aiming at the problems of high rigidity, low elasticity, difficult spinning and weaving and the like of pure hemp fibers, the invention provides the production method of the hemp blended woven fabric, which can effectively improve the weaving production efficiency and the cloth cover quality of the fabric by improving the rigidity and the toughness of hemp blended yarns.
The technical scheme of the invention is as follows:
the raw materials of the hemp blended yarn are hemp fiber, viscose and spun silk.
The first step is as follows: preparation of hemp blended yarn
The hemp blended yarn is prepared by adopting the current high-efficiency air-jet vortex spinning technology instead of the traditional ring spinning yarn forming process. The hemp fiber net, the viscose strips and the spun silk strips are weighed and mixed before the three fibers are uniformly mixed, so that the uniformity of fibers in the final drawn strips is ensured. The yarn forming process mainly aims at improving the holding force between fibers, namely, the transfer efficiency between the fibers is improved by adding special oiling agent in the spinning process.
The hemp blended yarn comprises the following raw materials in percentage by weight: the mixture ratio of hemp, viscose and spun silk is 45-55: 25 to 35:18 to 21;
the added special oil agent is paraffin white oil with the molecular weight of 350, and the dosage is 180 g/ton of yarn.
The second step: warping machine
Because the warp and weft yarns of the fabric adopt hemp blended yarns, compared with pure cotton yarns, the yarns have high rigidity, small elasticity and higher warping difficulty, and the main measures adopted for the purpose are as follows: the included angle of warp and lease reed is reduced to the department is regularly given humidity directly over the lease reed during the warping, promotes the yarn compliance, ensures that warping tension is even.
The included angle between the warp and the lease reed is controlled between 40 and 45 degrees, and one-time wetting operation is carried out at an interval of 15 +/-3 minutes; the warping speed is controlled slightly, and the warping speed is set to be 500 +/-50 m/min.
The third step: weaving
Weaving by using a Picanol GTMax rapier loom. The warp is not subjected to sizing treatment, so that the wear resistance of the warp is further improved, the weaving efficiency is improved, and a special wax block is additionally arranged at the unwinding position of a loom beam. Other weaving process parameters are as follows: the speed is 360rpm, the leveling time is 305 degrees, the height of the back beam is plus 8 grids, the front and back of the back beam are plus 4 grids, the height of the frame is plus 3 grids, the front and back are plus 6 grids, and the relative humidity of the workshop is 80-85%.
The placed special wax block mainly solves the problems of low weaving efficiency caused by unsized warp and uneven waxing caused by local excessive friction in the weaving process, and comprises the following manufacturing steps:
a. raw material selection
Domestic No. 56 pure white paraffin with oil content of 0.47%; domestic low-melting-point paraffin wax, the melting point is 51.3 ℃, and the oil content is 6.8%; domestic No. 70 microcrystalline wax.
b. The three paraffin raw materials are mixed according to the proportion of No. 56 paraffin 70 +/-2%: low melting paraffin 25 ± 2%: no. 70 microcrystalline wax is 5 +/-1 percent, and is placed together to be dissolved and fully stirred to be uniformly mixed. The purpose is to improve the oil content by using the second paraffin with low melting point and reduce the adhesion among yarns; the addition of a small amount of microcrystalline wax can enable the arrangement structure of the mixed paraffin molecules to be more compact, and improve the smoothness of the paraffin molecules in the process of waxing warp yarns;
c. and (3) injecting the uniformly mixed liquid paraffin into a mould with a specific shape, and cooling to obtain the required beam of weaving shaft wax block. The used mould with a special shape is conical, the diameter ratio of the big end to the small end corresponding to the upper end surface and the lower end surface of the mould is 1.1, the height is 25-30 cm, and the diameter of the big end is 5-6 cm. Because the common wax block is placed in the beam, the position of the common wax block is relatively fixed with the warp in the weaving process, so that grooves are partially ground, and the warp is not uniformly waxed. And the conical wax block can generate micro transverse movement in the weaving process due to the small and large end linear speeds, so that the local abrasion is relieved, and the large uniformity of the wax amount on the warp yarns is greatly improved.
The invention has the beneficial effects that:
the high-quality hemp blended yarn is spun through the optimization of the pre-spinning uniform mixing process and the vortex spinning process, and the high-efficiency production of the fabric is ensured by adding the special wax block and the optimization of the weaving process during weaving. The developed fabric has moisture absorption and air permeability and light and full hand feeling, not only overcomes the defect that pure hemp fabric is easy to wrinkle and itchy, but also has good shape retention.
