Abstract

PURPOSE:To obtain an interlining cloth having bulginess with low resistance to compression, etc., by reducing the weight of a cloth prepared from core-sheath type mixed spun yarn in which staple fiber of readily soluble polyester fiber and staple fiber of regenerated fiber are arranged in a specific proportion as warp yarn and/or weft yarn and then applying a resin thereto. CONSTITUTION:A cloth prepared from core-sheath type mixed spun yarn in which staple fiber of readily soluble polyester fiber containing, e.g. 5- sodium.sulfoisophthalic acid in an amount of 10-50wt.% based on the weight of the whole yarn as a core and staple fiber of regenerated fiber in an amount of 90-50wt.% based on the weight of the whole yarn as a sheath are mixed spun and arranged as warp yarn and/or weft yarn is subjected to weight reduction processing with an alkali. A resin such as a polyamide-based resin is then applied in the form of dots. Thereby, the objective interlining cloth, having reduced coherency of the yarn fiber and structure coherency as the cloth and low resistance to compression or bending with bulginess without adversely affecting the front fabric is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to interlining for women's thin blouses and dresses.

(Prior Art) Conventionally, for women's thin blouses and dresses, fabrics using yarns in the range of 20'S/1 to 80'S/1, such as cotton yarns and polyester cotton blend yarns, have been used.

(Problems to be Solved by the Invention) However, conventional interlinings have a rough and hard feel, have high resistance to compression and bending, have a negative impact on the outer material, and have poor adhesive properties.

The present invention eliminates the drawbacks of the conventional interlining and provides an interlining that does not adversely affect the outer fabric.

(Means for Solving the Problem) The present invention takes the following means to solve the problem. That is, in the present invention, staples of easily soluble polyester fibers are arranged in the core, staples of recycled fibers are arranged in the sheath, and the polyester fibers are 10% of the entire yarn.
Staple 1 of interlining and easily soluble polyester fiber, which is obtained by reducing the weight of a woven fabric in which spun yarn with a core-sheath structure accounting for ~50% by weight is used for the warp and/or weft, and the resin is graded.
This interlining is made by reducing the weight of a woven fabric in which a blended yarn consisting of 0 to 50% by weight and 90 to S○% by weight of recycled fiber staples is used for the warp and/or weft and is coated with resin. The present invention will be explained in detail below.

First, the yarn used in the present invention includes a core-sheath structured spun yarn. In this core-sheath structured spun yarn, staples of easily soluble polyester fibers are arranged in the core, and staples of recycled fibers are arranged in the sheath. This is because the weight is reduced in the woven fabric, resulting in fullness, adhesive properties, and low resistance to compression and bending, so that it does not adversely affect the outer material. In the opposite arrangement, the bulge will be poor, and the gaps between the core staples will be small, resulting in poor adhesion. Note that the recycled fibers include polynosic fibers, rayon fibers, cupra fibers, etc., and the thickness is preferably 0°3 to 1.5d.
More preferably, the length is 0°5 to 1.2d, and the length is 51
Equal length cuts of mm or less are preferred. On the other hand, examples of the easily soluble polyester fiber with a core include polyethylene terephthalate fiber containing 5-sodium sulfoisophthalic acid, polyester fiber dyeable under normal pressure, and polyester fiber dispersible under normal pressure, with the former two being preferred.

Moreover, the thickness is preferably 0.3 to 1.5 d, and more preferably 0.3 to 1.5 d.
．． 5 to 1.2 d is more preferable. In addition, it is preferable to cut the length to equal lengths of 51 or less. Next, a blended yarn obtained by blending the above-mentioned easily soluble polyester fiber and recycled fiber staples is used in the present invention. The thickness and length are the same as those already described. The easily soluble polyester fiber accounts for 10 to 50% by weight of the entire yarn,
Regenerated fibers account for 90-50% by weight. This is to improve drapability. Even in the case of blended yarns, gaps are created due to the easily soluble polyester fibers that dissolve, resulting in good adhesion and reduced resistance to compression and bending, which has the effect of not having a negative impact on the outer material. have

Such core-sheath structure spun yarn or blended yarn is both warp and weft,
Alternatively, it is used for either the warp or weft and is processed to reduce the weight of the fabric, but in order not to have a negative impact on the outer material as an interlining, the fabric weight (g/a) is 3.
0 to 100 g/bag is preferred, and 40 to 80 g/bag is more preferred. Further, the thickness of the spun yarn or blended yarn is preferably 20 to 80'S/1.

Plain weave is preferred as the fabric, and the cover factor is 9.
0 to 17.0 is preferred. Here, the degree of hippo weight loss is
It is preferably 10 to 50%, more preferably 20 to 35%. The weight loss fabric is preferably dotted with a resin such as polyamide or polyester.

Here, the method for manufacturing the interlining material of the present invention will be explained. First, a fabric is woven at a predetermined basis weight using the above-mentioned core-sheath structure spun yarn or blended yarn as the warp and/or weft, and the gray fabric is subjected to a weight reduction process using caustic soda to create easily soluble polyester fibers. By dissolving or removing all or a considerable amount of fibers, the binding force of the fibers of the yarn is reduced, and at the same time, the binding force of the fabric as a fabric is lowered, thereby improving the soft texture and drapability, as well as lowering the resistance to compression and bending. It is something that can be done.

(Example) Example 1 70% by weight of polynosic fiber (0.7dX38mm)
, a combination of 30% by weight of polyethylene terephthalate fibers (1, OdX38m) containing 5-sodium sulfoisofucuric acid, with the polyethylene terephthalate fiber as the core and the polynosic fiber arranged in the sheath, a core-sheath structured spun yarn 40'S /1 was used for the warp and weft, and a plain weave (wet weight: 55 g/m) with a density of 55 x 50 threads/inch was woven. The gray fabric was processed to reduce its weight by about 30% with a 15% NaOH solution,
Next, a dyed finish was applied, and a polyamide resin was applied in dots to produce a soft interlining material with excellent drape properties equivalent to 60'S/1 yarn, which was then glued to a women's thin blouse. By following this method, a blouse with excellent drapability without impairing the texture and appearance of the outer material was obtained.

Example 2 65% by weight of polynosic fiber (0.7dX38mm)
Polyethylene terephthalate (1, Od, X38IIIN) containing 5-sodium sulfoisophthalic acid was
% by weight blended yarn (40'S) was used for both the warp and weft, and the plain weave (weave weight 5
7 g/rd).

When used on the inside of a casual dress, the outer material had excellent texture and drapability.

(Effects of the Invention) As described above, the interlining material of the present invention has excellent bulge, low resistance to compression and bending, and does not have any adverse effects on the outer material.
