Abstract

PURPOSE:To obtain the title screen excellent in shape retainability and dimensional stability, good in airtightness and shading nature by making a knit fabric made up of sheath-core type conjugate yarn composed of two different polyester fibers into a pleat under specified conditions and by hot-press setting of this pleat. CONSTITUTION:Firstly, a knit fabric is produced in such a way that sheath-core type conjugate polyester filament yarns made up of (A) as the core, polyethylene terephthalate and (B) as the sheath, a low-melting polyester account for >=20wt.% of the total yarns and >=40wt.% of the warps and/or wefts. The knit fabric is then heat-treated at temperatures higher than the melting point of the component B but lower then the melting point of the component A to effect fusing (part of) the intersections for said filament yarns followed by folding the resultant knit fabric in such a direction that >=40wt.% of said filament yarns are used to form a pleat, which is then hot-pressed at temperatures lower than the melting point of the component A by 1 to 30 deg.C and heat-set, thus obtaining the objective screen.

(Prior art) Traditionally, the use of fabric for screens such as blinds has been preferred because of its ease of dyeing and other processing, as well as its good texture and appearance. It was often used as a roll-up type roll blind, or by cutting strips and connecting them vertically or horizontally as a Henessian blind or vertical blind. However, roll blinds are limited to vertical use. In addition, befu cyan blinds and vertical blinds not only lack airtightness and light-blocking properties, but also have poor operability due to the thin processed fabric (and the orientation of the strip of fabric may be reversed if a weight is not attached). However, it has the disadvantage that it is difficult to obtain a practical product.

Therefore, it is possible to form the fabric into a pleated screen that has excellent airtightness and light-shielding properties, but ordinary fiber structures have poor formability due to their drapability, and they also tend to fray on the cut surface. Due to this problem, it is impossible to obtain a pleated screen that is practical. Separately, as a fiber structure with excellent moldability, one in which low melting point fibers are mixed is known, as described in JP-A No. 59-59969. Although it can be used as a hard finishing fabric, it lacks shape retention and dimensional stability, and cannot be used to manufacture pleated screens that are repeatedly opened and closed.

As a result, in all of the Examples shown in Table 1, processed fabrics that were stably pleated and had appropriate hardness were obtained. When pleated screens were manufactured using these processed fabrics, we were able to obtain products with excellent design effects that could be stably used in both vertical and horizontal screens.

Furthermore, in the present invention, since the contact points of the filaments are joined by melting the sheath portion of the composite filament, a product with excellent dimensional stability without misalignment can be obtained even with thin or coarse fabrics. In addition, this bonding does not substantially damage the overall appearance and feel of the fabric.
By using a combination of decorative threads, highly fashionable products can be obtained. In addition, anti-dyeing and flame-retardant treatments are also possible.
