Description

Description Weaving of pure Chinese hemp high-weak and strong yarn home textile fabric: ^ Technical field

The invention relates to a weaving method for a home textile fabric, in particular to a weaving method for a high-strength pure hemp weak-strength yarn home textile fabric.

Background technique

The traditional weaving processing route of high-density and high-density home textile fabrics is as follows: First step ----- warping (low tension); second step...- - sizing (two high and one low: high pressure, high concentration, low viscosity) The third step...--hand-wearing; fourth step...--weaving (early opening, late beating, middle back beam, medium tension). The characteristics of pure Chinese hemp viscose high count yarn are: high fidelity and low strength, low yarn strength, high wet elongation, low wet strength, high twist, easy to twist the yarn, and difficult sizing production. The cloth machine has many breaks, more breaks, and uneven cloth surface. It uses pure Chinese hemp rubber high-strength weak yarn as raw material. When weaving home textile fabrics by traditional craft route, double weaving shaft processing is easy to produce yin and yang surface, cloth The surface quality is poor, and it is unable to meet the requirements for the production of high-grade bedding fabrics with high-strength pure hemp weak yarn.

Summary of the invention

The object of the present invention is to overcome the insufficiency of the prior art weaving method for producing high-grade bedding fabrics by using pure hemp high-strength weak yarns, and to provide weaving of high-strength pure hemp weak-strength yarn home textile fabric with high weaving efficiency and reliable quality. method.

Solution of the invention: The following process route is used: warping... sizing...-through-weaving.

1. Warping

Micro-tension control of Hanma high-strength weak yarn on warping machine, warp beam opening 2400mm, total length 18338-23520, single-axis head 750-1040, and cylinder 20-28, tension rod delay Time 1-4 seconds, tension bar tension 4-10g, brake pad delay time 2-6 seconds, barrel capacity 750-1040, achieve multi-head and less axis, reduce the movement between the single yarn and the warp beam The difference in tension effectively ensures uniform warp beam tension, uniform winding, and uniform alignment. The traditional warping machine: the capacity of the cheese is small, the single yarn is easy to swim, the number of warp beams is large, the tension of the yarn is uneven, and the uniform micro tension control cannot be achieved. Strong yarn production requirements for high-quality bedding fabric weaving processing.

2, sizing

Winding on the sizing machine, the tension is 4500N-5500N, the sizing mode is single-dip single pressure, the pulp force is 18-24 KN, the wet elongation is 0.1-0.2%, the skein is prevented from twisting, and the warp beam unwinding tension 650- 750N, using pulp The tank capacity is 320L, the length of the dipping is 60-80cm, and the tension of each zone is easy to adjust. The tension of the two pulp grooves is equal, and the winding tension of the weaving shaft is uniform. The traditional sizing formula, the post-slurry yarn is brittle, the smashing teeth are many, the cloth machine has many broken ends, and the cloth surface quality is poor, which can not meet the requirements of high-purity pure hemp weak yarn production of high-grade bedding fabric weaving processing.

3, wearing comprehensive

Due to the high number of high-density pure hemp bed fabrics, the traditional method of wearing the heddle, the yarn is not uniform, the yarn is uneven, the twister is more, the machine is more difficult, the quality of the cloth is poor, can not meet Gaozhi pure Hanma weak strong yarn produces high-grade bedding fabric weaving processing requirements. If the artificial yarn is used to make the yarn, it is easy to cause the twisted yarn of the yarn and it is easy to wear. The invention adopts the Swiss-made STAUBLI OPAL-3600 automatic splitting machine, the Swiss-made STAUBLI DELTA 110-3600 automatic wearing machine, the automatic splitting machine, the upper and lower splitting, and the automatic wearing machine for automatic wearing. The splitting is accurate, the twisted yarn of the yarn is reduced, the yarn is taken accurately, the yarn is evenly distributed, the accuracy of the fit is ensured, and the difficulty of driving on the machine is reduced. To meet the requirements of high-strength pure hemp weak yarn production of high-grade bed fabric weaving processing.

4, weaving

Low-tension weaving with wide-width single-weave looms, opening time 280-290 degrees, main spray time 70-80 degrees, upper machine tension 3000-4000 N, speed 450n/min, rear beam height less than 4 cm, weaving workshop Temperature: 25-30 ° C, relative humidity 68-72%, when the relative humidity is low, the yarn has good strength, good elasticity, good wear resistance, but too low, the broken head will increase; increase the grip of the temple The tension is maintained to prevent the side smashing during the weaving production of the hemp viscose yarn. It effectively solves the problem that the traditional double weaving machine can not guarantee the uniformity of the two weaving shafts, the tension and the width of the width of the wide door, ensuring the quality of the cloth and making the yin and yang and the machine break. cut back.
