Currently, global integration is becoming increasingly apparent. International advanced washing concepts have fully entered the Chinese washing market. Concepts such as washing dragons and integrated washing have been widely accepted in medium and large laundry factories. However, how to truly make good use of these advanced technologies to maximize washing benefits is a question worth considering. The best configuration for applying washing dragons abroad is two washing dragons plus one integrated washing system.
The integrated washing system connects multiple single machines through a logistics system to achieve a fully automated washing process from washing to drying. It is a comprehensive system project. Customers can choose combinations based on their washing volume and laundry room conditions, and each module can be flexibly adjusted according to the customer's actual situation. For example, the sorting logistics system can select the form of feeding carts or hanging bag sorting systems based on the height and area of the customer's laundry room; similarly, for feeding carts, one can choose a ramp feeding cart or an overhead feeding cart; for the washing system, one can choose a standard inclined washing machine or an inclined washing machine with a funnel; the entire logistics system can use conveyor belts, hanging bag conveyors, or a combination of both.
Especially with its unique advantages, the integrated washing system has been used for decades in developed countries such as Europe, America, and Japan. Today, it occupies half of the social washing market.
1. The essence of integrated washing system washing is single-machine washing. Different types or colors and special linens (such as mops, work clothes, dust mats, blankets, etc.) can all be washed.
2. The washing and dehydration machine uses a 360° rotation washing method with strong mechanical force, separate water inlet and outlet rinsing, good effect, suitable for washing different stains.
3. It can be customized according to different customer sites and environments and can be continuously expanded according to increased washing volume.
4. Maintenance and repair are more flexible, not affecting other washing due to single machine maintenance, nor affecting overall washing due to partial faults.
5. Through flexible combinations of different energy efficiencies, water and energy saving effects can be achieved.

2. Take auxiliary materials
Take auxiliary materials from the left and right patch pockets at the bottom of the jacket, completing the weaving at the edges of the left and right circular hems. First, cut open and lift the surface topstitching of the patch pocket, then use a ballpoint pen inside the patch pocket to draw a 13*14cm rectangle for the auxiliary material. The auxiliary material should be slightly larger than the actual size. Cut the warp and weft yarns of the four edges of the auxiliary material straight and vertical, then tear off the black backing fabric on the back of the auxiliary material (see Figure 2).
Figure 2
3. Fix auxiliary materials
Lay the auxiliary material on the lengthened bottom edge where there is a missing part. Leave a 1cm fold on the left edge of the auxiliary material, then cut off the excess auxiliary material. Sew the downward fold with silk thread and sew it together with the original fabric at the splicing position. After fixing, iron it flat (see Figure 3).
Figure 3
4. Make standard lines
At the folded edge of the auxiliary material, weave a white silk thread in a plain weave pattern of "over one, under one." At the lengthened bottom edge of the original fabric, also weave a white silk thread as the "standard line" for splicing the two fabrics together (see Figure 4).

4. Methods and steps of weaving
1. Weaving the "vertical opening"
The weaving of the vertical opening uses the "standard line" as the boundary. All warp and weft yarns are operated with wool yarn. From left to right, find the first weft yarn of the two fabrics and weave the stitches in a plain weave pattern of "over one, under one." When weaving to the "standard line" of the two fabrics, it forms a complete weave (i.e., the two white threads become "over one, under one") (see Figure 5). Each time a weft wool yarn is woven in, adjust the tension of the wool yarn. All stitches on both sides are backstitched to increase firmness, so that the two fabrics after weaving can become a good whole. After weaving the vertical opening, pull out the two white "standard lines" (see Figure 6).
Figure 5 Figure 6
2. Weaving "corners" and "horizontal circular hems"
(1) When weaving the "corner," follow the diagonal change of the "corner" to gradually complete the transition of the "corner," transitioning to the "horizontal opening" of the circular hem. Find the first warp yarn (the white standard line on the auxiliary material) and make it cross with the last weft yarn of the vertical opening. The cross is the transition point of the "corner" (see Figure 7).

(2) When weaving the "horizontal circular hem," due to the curvature change of the horizontal opening edge, the weft wool yarns at the horizontal opening weaving are not on the same yarn. When weaving, the warp wool yarns of the two fabrics must be aligned one by one, and the picking and pressing at the seam vary with the curvature. The picking and pressing are always "over one, under one," complete and full, with stitches woven back in a pattern of one long and one short or two long and two short (see Figure 8).

3. Weaving the "vertical circular hem"
After the horizontal circular hem edge weaving is completed, the first wool weft yarn is woven in the direction of the vertical circular hem edge right next to the last wool warp yarn, forming a cross intersection, completing the conversion from "horizontal" (horizontal opening) to "vertical" (vertical opening), and aligning each wool weft yarn of the two fabric pieces. The picking and pressing at the seam vary with the curvature, always maintaining an "up-down-up-down" pattern (see Figure 9).

5. Finishing
Starting from the front side of the fabric, gently lift the recessed yarns at the seam with a large pick needle, and push down the raised wool yarns with the needle to smooth them. From the back side of the fabric, cut several small notches at the folded edge of the auxiliary circular hem to relieve tension in the curvature. Split open the folded edge at the seam, spray some water, place a layer of dry cloth and a layer of wet cloth, and iron flat. After drying, use a large pick needle on the front side of the fabric along the woven seam, first from bottom to top, then from top to bottom, gently scraping out a small amount of fluff (see Figure 10).
Figure 10
6. Cutting and Sewing
After the left and right sides are woven, ask the tailor to reasonably cut according to the lengthened circular hem size. The auxiliary material position inside the pocket can be replaced with other fabrics and sewn, then cover with the patch pocket and sew with visible stitches.
