Description

Technical Field

[0001] This utility model relates to a yarn strip and a comfortable sleeping blanket made from the yarn strip, and more particularly to a weighted yarn strip and a comfortable sleeping blanket made from it. Background Technology

[0002] Weighted blankets distribute pressure evenly across the body, creating a sense of security and allowing the body to regulate itself, increasing serotonin and melatonin levels, thus relieving stress and promoting sleep. There are various types of weighted blankets. Some adjust weight by filling the blanket with materials such as silica beads or plastic granules, while others adjust weight by changing the weight of the blanket's raw materials. Adjusting weight through filling methods not only affects the blanket's breathability but also poses risks such as inconvenient cleaning, filling displacement, or leakage. Therefore, adjusting the weight of the blanket's raw materials is now the more common method for weight adjustment.

[0003] For example, patent application number 201980083401.9 discloses a layered yarn and weighted blanket for deep pressure therapy, in which layered yarns of a certain length are interlocked to form the weighted material. The layered yarn includes an outer tube extending longitudinally from a first end to a second end. The outer tube defines a conduit extending longitudinally from the first end through it to the second end. Multiple inner layers of material are disposed within the conduit and extend longitudinally from the first end to the second end. The weight of the yarn can be adjusted by changing the number of inner layers; however, such convolution and stacking cannot guarantee that all inner sheets have a consistent folded shape, which can easily lead to different final yarn shapes and is not conducive to standardized production. Utility Model Content

[0004] The purpose of this invention is to provide a weighted yarn strip and a comfortable sleeping blanket made from it. It has the advantages of convenient weight adjustment and ease of standardized production.

[0005] The technical solution of this utility model is: a weighted yarn strip, the weighted yarn strip including a cylindrical braided part made of yarn, the braided part having one or more sets of openings from one end of the length direction to the other end of the length direction, and the openings having transverse lines for connecting the two ends of the braided part in the width direction.

[0006] In the aforementioned type of weighted yarn, the length of the transverse line at the opening is less than the unfolded length of the adjacent weave section.

[0007] In the aforementioned weighted yarn, the two ends of the braided portion in the width direction are provided with at least one set of curled portions that curl inward in the opening direction.

[0008] In the aforementioned type of weighted yarn, the knitting part is specifically knitted using a plain knitting method to form a tubular structure.

[0009] A comfortable sleeping blanket made of weighted yarn strips, wherein the comfortable sleeping blanket is woven from the aforementioned weighted yarn strips as raw material.

[0010] In the aforementioned type of weighted yarn comfort blanket, the density of the comfort blanket is not less than 2000 grams per square meter.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The weighted yarn strip of this application is woven from yarn. The weight of the weighted yarn strip can be adjusted by changing the size and number of openings in the weaving part. The weaving parts are connected together by transverse lines to form a tubular fabric, which is convenient for subsequent processing into a comfortable sleeping blanket. In this way, the weight of the yarn strip can be adjusted by controlling the width of the weaving part and the transverse lines or by adjusting the number of openings. The weighted yarn strip has a more stable size and shape, which is convenient for standardized production. Different weight models of weighted yarn strips can be produced using the same set of equipment.

[0013] 2. This application utilizes the tension difference between the braided section and the horizontal line, and the characteristic that the edge of the braided section is prone to curling, to make the edge of the braided section curl and cover the horizontal line, thus improving the aesthetics.

[0014] 3. The width and number of openings of the yarn weaving section and the transverse lines can be achieved by skipping stitches on a circular loom, which makes processing more convenient, saves a lot of manpower and equipment costs, and improves processing efficiency.

[0020] The markings in the attached diagram are: 1-weave section, 2-horizontal line, 1.1-curl section. Detailed Implementation

[0021] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] Example. A weighted yarn, configured as follows: Figure 1-3 As shown, the weighted yarn includes a cylindrical braided section 1 woven from yarn. The braided section 1 has one or more openings from one end of the length direction to the other end of the length direction, and the openings are provided with transverse lines 2 for connecting the two ends of the braided section 1 in the width direction.

[0023] The length of the transverse line 2 at the opening is less than the unfolded length of the adjacent braided section 1.

[0024] The braided part 1 has at least one set of curled parts 1.1 that curl inward toward the opening direction at both ends in the width direction.

[0025] The knitting section 1 is specifically knitted using a plain knitting method to form a tubular structure.

[0026] A comfortable sleeping blanket made of weighted yarn strips, consisting of... Figure 5 As shown, the comfort blanket is woven from the aforementioned weighted yarn strips.

[0027] The density of the comfort blanket is no less than 2000 grams per square meter.

[0028] The weighted yarn of this application includes a braiding section 1 and one or more sets of transverse threads 2 located at the openings of the braiding section 1. The transverse threads 2 can be formed by skipping stitches during the processing of the braiding section 1 on a circular knitting machine. The number of openings and the length of the transverse threads can be controlled by setting the number of skipped stitches, thereby adjusting the weight of the weighted yarn. Weight adjustment is convenient. Typically, the number of stitches in the braiding section of the weighted yarn is 3-120, and the number of stitches at the openings is 1-50. Different weight grades of weighted yarn can be produced using the same set of equipment, effectively reducing labor and equipment costs. When producing weighted yarn, the operator can adjust the number of openings according to the required weight. To increase the weight, the number of openings and skipped stitches can be reduced. If the weight requirement is met without openings, then openings are not necessary. To decrease the weight, the number of openings and skipped stitches can be increased. In this way, the same set of equipment and molds can produce weighted yarns with a wide weight range. Further... Figure 4As shown, if the horizontal line 2 at a set of openings is too long, an extra stitch is added at the opening. Due to the different tension between the knitting part and the horizontal line of the weighted yarn, and the tendency of the knitting part edge to curl, the curled edge of the knitting part covers the horizontal line, resulting in better aesthetics. The parameters of the weighted yarn can be kept consistent, which is conducive to standardized production. Typically, the density of a comfort blanket should not be less than 2000 grams per square meter. For example, a comfort blanket with dimensions of 2030mm*2200mm weighs 11300 grams, and a comfort blanket with dimensions of 1520mm*1270mm weighs 4500 grams. This allows the comfort blanket to provide pressure to the body. Furthermore, the density of the comfort blanket can be adjusted by changing the weight of the weighted yarn or by changing the knitting structure. Because the weight of the weighted yarn is easy to adjust, the density of the comfort blanket can be quickly adjusted without changing the knitting structure.
