Abstract

To provide bedding that has high heat retaining property by containing an air layer and is rich in design property by giving stitch to form irregularities on base fabric in elastic yarn using a quilt sewing machine, etc., after base fabric knitting in the application concerned, for solving problems in which the application of elasticity to fabric is implemented by inserting elastic yarn in the knitting even if being a knit fabric or a texture fabric, accordingly, a degree of freedom is limited such that a rubber thread insertion direction is limited to one direction, and the design property becomes poor.SOLUTION: A stitch is given using elastic yarn such as a rubber thread while applying tension to a base fabric for bedding formed by a knit knitting machine or a weave machine such as warp knitting machines and making it flat. The pattern of the base fabric is coarsely knitted so that the weight of the bedding after completion may become 50 g/mto 400 g/m. The stitch is given in elastic yarn while applying tension to the finished base fabric, and it is contracted in the vertical/horizontal directions of the size of the base fabric serving as the original so as to become 15% to 50% in length.SELECTED DRAWING: Figure 2

Description

  The present invention relates to bedding made by shrinking a fabric knitted or woven as a blanket or a blanket.

  As a method for imparting heat retention to bedding such as a blanket, it is known to perform a raising process or to double-bond Russell knitting to make a Mayer blanket. Among them, there is an invention of a blanket having a structure in which rubber-like elastic fibers are knitted into a Meyer's blanket (weft) and stretched and restored in the warp and knitting directions, and the elastic recovery function is expanded (Patent Document 1). .

  On the other hand, the elastic yarn having the shrinkability is used at the time of knitting in both the woven fabric and the knit fabric.

  As a method for exposing wrinkles on the surface of a base fabric such as a woven fabric, there is a heat setting process in which the yarn structure after knitting is thermally contracted by heat treatment.

  There was bedding using quilting fabric including outer material, lining and padding intervening between them (Patent Document 2) Bedding that was stitched like quilting using elastic yarn on the base fabric after knitting There wasn't.

  In addition, it is desirable that the bedding that is used daily and kept clean should be easy to wash and dry. However, in order to achieve this, if the fabric is made thin and light, heat retention cannot be maintained.

  Therefore, the applicant of the present application devised and developed the warp knitted wool fabric of Patent Document 3. This was obtained by forming the base fabric into a coarse knitted fabric by floating and knitting the fabric that becomes the ground texture, and inserting rubber threads in the lateral direction to give gathers in a bellows shape It is.

  The warp knitted wool fabric of Patent Document 3 is excellent as a bedding to be attached to the body with a soft texture because it is thin and light and has heat retention properties, and has elasticity, but the rubber yarn insertion direction is uniform. The direction was limited and the degree of freedom was limited. This is because an elastic yarn that contracts the base fabric is used during knitting. Therefore, in the present application, it is an object to provide a bedding having a high heat retention and an excellent design including an air layer by stitching with an elastic yarn using a quilting sewing machine after knitting the base fabric to form irregularities on the base fabric. And

Stitching is performed using elastic yarn while applying tension to a base fabric formed by a knit knitting machine such as a warp knitting machine or a loom. The base fabric is knitted roughly so that the weight of the completed bedding is 50 g / m 2 to 400 g / m 2. Stitching the finished base fabric with elastic yarn while applying tension, 15% to 50% in the vertical and horizontal directions of the original base fabric dimensions
Shrink to length.

  There is a high degree of freedom in stitching, and it is possible to apply complex patterns and patterns to bedding. When stitches are formed at regular intervals in the vertical and horizontal directions of the base fabric in the shape of a grid, the place surrounded by the elastic yarn becomes a convex portion, and the heat retention is enhanced including the air layer. A soft feeling and a unique design arise because the surface of the base fabric is uneven and has a three-dimensional shape.

  Since it has moderate shrinkage, it is difficult to produce a gap along the body even if it is turned over.

  Since the base fabric is a knitted fabric, there are many gaps between the yarns, and each of them swells in three dimensions to increase heat retention.

  The unevenness appearing on the surface can provide not only heat retention but also breathability and provide a comfortable bedding.

Explanatory drawing which shows the state stretched flatly by stitching with the rubber thread to the blanket which concerns on this invention in the vertical and horizontal direction. Explanatory drawing which shows the state in which shearing was formed in the vertical and horizontal direction in the natural state. Explanatory drawing which shows the state which applied the stitch so that it might become a diamond pattern of a horizontal direction.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, this is merely an example of the embodiment, and the present invention is not limited to this embodiment.

  First, the warp knitted fabric that becomes the blanket base fabric is knitted rough and lightly with an areal density (weight per unit area) of 50 g / m 2 to 400 g / m 2 (1 in FIG. 1). The fabric is fed while tension is applied to the obtained base fabric 1, and a stitch sewing machine is applied in the vertical and horizontal directions using elastic yarn. In this embodiment, ten stitch sewing machines are applied in the horizontal direction. On the other hand, five stitch sewing machines are applied in the vertical direction. By applying stitch sewing in the vertical and horizontal directions, a substantially rectangular pattern appears on the surface of the blanket.

  The drawing shows a flat state stretched with tension, but actually contracts in the vertical and horizontal directions (FIG. 2). Fine wrinkles appear on the entire blanket.

  In addition, if the width is narrowed in the horizontal direction at the upper and lower ends of the blanket and the stitches are finely inserted, the upper and lower ends will contract particularly strongly, and the blanket will be attached to the shoulders and legs to prevent gap air and keep warmth. It will be even higher.

  By changing the stitch pitch of the stitches, it is possible to change the contracted state and shearing shape applied to the base fabric.

  Moreover, the expression on the surface of the base fabric can be changed by combining straight seams and curved seams.

  In FIG. 3, a diamond pattern in the horizontal direction appears by applying a large number of diagonally intersecting stitches to the base fabric 4. Each pattern surrounded by the elastic yarn becomes three-dimensional and contains air, thus increasing the heat retention.

  The kind of thread | yarn used for the base fabric of the blanket which concerns on this invention, and an elastic thread | yarn is not specifically limited. Various applications are also possible for the sewing method, that is, the number and shape of stitches. Various designs and combinations are conceivable from the viewpoint of the pattern that appears on the surface of the base fabric.

  On the other hand, when the shrinkage degree is 15% to 50% of the vertical and horizontal dimensions of the base fabric and the finished size is a general single size blanket (140 cm × 200 cm), the size of the base fabric before stitching is about 165 cm × 235 cm, for example. To 280 cm × 400 cm. The method of applying the contraction may be only in the horizontal direction or in both the vertical direction and the horizontal direction. Of course, the contraction ratios in the vertical and horizontal directions may be different.

  If the dimensional change is less than 15%, there will be less wrinkles and shirring on the surface of the base fabric, and it will not become a three-dimensional shape. . On the other hand, when the shrinkage rate is 50% or more, the weight of the completed blanket or blanket becomes heavy.

  Since the present invention has heat retention and flexibility, it can be generally used for bedding such as blankets, comforter covers, and blankets.
