Description

Technical Field

[0001] The invention relates to a sleeping blanket made of a yarn strip and a weighted yarn strip and a preparation process thereof, in particular to a sleeping blanket made of a weighted yarn strip and a weighted yarn strip and a preparation process thereof. Background Art

[0002] The pressure of a gravity blanket is evenly distributed on the human body, giving people a sense of security, allowing the user's body to adjust itself, increasing serotonin and melatonin levels, thereby achieving the effect of relieving stress and helping sleep. There are many types of gravity blankets. Some achieve weight adjustment by filling the blanket with fillers such as silica beads, plastic particles, etc., and some achieve weight adjustment by changing the gram weight of the blanket's raw materials. The method of adjusting the weight of a gravity blanket by filling not only has the defect of affecting the air permeability of the gravity blanket, but also has the risk of inconvenience in cleaning and the risk of filler displacement or leakage. Therefore, the weight of the gravity blanket is often adjusted by changing the gram weight of the raw materials of the gravity blanket.

[0003] For example, the patent with application number 201980083401.9 discloses a layered yarn and a weighted blanket for deep pressure therapy, in which a certain length of layered yarn is looped with each other 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 through it from the first end to the second end. Multiple inner layers of the material are arranged in 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, but such convolution stacking cannot ensure that the folding shape of all inner sheets is consistent, which easily leads to different final shapes of the yarn, which is not conducive to standardized production. Summary of the invention

[0004] The object of the present invention is to provide a weighted yarn strip, a comfortable sleeping blanket made of the weighted yarn strip and a preparation process thereof. The weighted yarn strip has the advantages of convenient weight adjustment and easy standardized production.

[0005] The technical solution of the present invention is: a weighted yarn strip, which includes a cylindrical woven portion woven from yarns, wherein the woven portion is provided with one or more groups of openings from one end in the length direction to the other end in the length direction, and the openings are provided with transverse lines for connecting the two ends in the width direction of the woven portion.

[0006] In the aforementioned weighted yarn strip, the length of the transverse line at the opening is smaller than the unfolded length of the adjacent woven portion.

[0007] In the aforementioned weighted yarn strip, at least one group of curled portions curled inwardly in the opening direction are provided at both ends of the woven portion in the width direction.

[0008] In the aforementioned weighted yarn strip, the braided portion is woven using a flat knitting method to form a tubular structure.

[0009] A preparation process for a weighted yarn strip comprises weaving the weighted yarn strip through a circular loom, wherein an opening of a woven part of the weighted yarn strip and a transverse line connecting two ends of the woven part are formed by skipping stitches of the circular loom.

[0010] In the aforementioned process for preparing a weighted yarn strip, the adjustment of the gram weight of the weighted yarn strip can be achieved by changing the number of openings or setting the number of skipped stitches at the openings.

[0011] The utility model relates to a comfortable sleeping blanket made of weighted yarn strips, wherein the comfortable sleeping blanket is woven by using the aforementioned weighted yarn strips as raw materials.

[0012] In the aforementioned comfortable sleeping blanket made of weighted yarn strips, the density of the comfortable sleeping blanket is not less than 2000 grams per square meter.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The weighted yarn strip of the present application is woven from yarns, and the weight of the weighted yarn strip is adjusted by changing the size and number of openings in the woven part. The woven 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 woven part and the transverse line or adjusting the number of openings. The size and shape of the weighted yarn strip are more stable, which is convenient for standardized production. The same set of equipment can be used to produce weighted yarn strips of different weights.

[0015] 2. The present application sets a woven part and a transverse line, and utilizes the different tensions between the woven part and the transverse line, and the characteristic that the edge of the woven part is easy to curl, so that the edge of the woven part curls to cover the transverse line, and the aesthetics is better;

[0016] 3. The opening of the woven part of the weighted yarn and the width and number of the transverse lines can be achieved by jumper weaving on a circular loom, which is more convenient to process, can save a lot of manpower and equipment costs, and improve processing efficiency.

[0026] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0027] Embodiment. A weighted yarn strip, comprising: Figure 1-3 As shown, the weighted yarn strip includes a tubular woven portion 1 woven from yarns, wherein the woven portion 1 is provided with one or more groups of openings from one end in the length direction to the other end in the length direction, and the openings are provided with transverse lines 2 for connecting the two ends of the woven portion 1 in the width direction.

[0028] The length of the transverse line 2 at the opening is smaller than the unfolded length of the adjacent woven portion 1 .

[0029] At least one set of curled portions 1.1 curled inwardly in the opening direction are provided at both ends of the woven portion 1 in the width direction.

[0030] The braided portion 1 is knitted using a flat knitting method to form a tubular structure.

[0031] A preparation process for a weighted yarn strip comprises weaving the weighted yarn strip through a circular loom, wherein an opening of a woven part of the weighted yarn strip and a transverse line connecting two ends of the woven part are formed by skipping stitches of the circular loom.

[0032] The weight adjustment of the weighted yarn strip can be achieved by changing the number of openings or setting the number of skipped stitches at the openings. Usually, the number of needles in the woven part of the weighted yarn strip is 3-120, and the number of needles at the opening is 1-50.

[0033] A comfortable sleeping blanket made of weighted yarn strips, comprising: Figure 5 As shown, the sleeping blanket is woven using the above-mentioned weighted yarn strips as raw materials.

[0034] The density of the sleeping blanket is not less than 2000 grams per square meter.

[0035] The weighted yarn of the present application includes a woven portion 1 and one or more groups of transverse lines 2 arranged at the opening of the woven portion 1. The setting of the transverse lines 2 can be formed by skipping stitches when the circular loom processes the woven portion 1, and the number of openings and the length of the transverse lines can be controlled by setting the number of skipped stitches, so as to adjust the gram weight of the weighted yarn. The gram weight adjustment is convenient, and the same set of equipment can be used to produce weighted yarns of different weight models, which can effectively reduce manpower and equipment costs. When producing weighted yarns, the staff can adjust the number of openings according to the gram weight of the required weighted yarn. When the gram weight needs to be increased, the number of openings and the number of skipped stitches are reduced. When the equipment produces the yarn without setting the openings and the gram weight requirement of the weighted yarn is met, the opening setting can be omitted; when the gram weight of the weighted yarn needs to be reduced, the number of openings and the number of skipped stitches are increased. In this way, the same set of equipment molds can produce weighted yarns with a larger weight range. Further, Figure 4 As shown, when the transverse line 2 at a group of openings is too long, a stitch is added at the opening. Due to the different tensions between the woven part and the transverse line of the weighted yarn strip, the edge of the woven part is easy to curl, so that the edge of the woven part curls to block the transverse line, which is more aesthetically pleasing. The parameters of the weighted yarn strip can be kept consistent, which is conducive to standardized production. Usually, the density of the sleeping blanket should not be less than 2000 grams per square meter. For example, the weight of the sleeping blanket with a size of 2030mm*2200mm is 11300 grams, and the weight of the sleeping blanket with a size of 1520mm*1270mm is 4500 grams. In this way, the sleeping blanket can exert pressure on the human body, and the density of the sleeping blanket can be adjusted by changing the gram weight of the weighted yarn strip or by changing the knitting structure. And because the gram weight of the weighted yarn strip is easy to adjust, the density of the sleeping blanket can be quickly adjusted without changing the knitting structure.
