experiment example

[0055] Hereinafter, the present invention will be specifically described using experimental examples and the like.

[0056] In the following experimental examples and the like, the following measurement and evaluation methods, devices, and the like were used.

[0057] (1) Air permeability

[0058] Measured by JIS-L-1096 8.27.1A method (Fraser method). The unit is cc / cm 2 ·Second.

[0059] (2) Determination of air permeability after oblique deformation

[0060] Such as figure 1 As shown, the sample was cut obliquely to 15 cm x 15 cm, and the air permeability was obtained by the same measurement method as in (1) above after deforming the sample under the following conditions using TENSILON RTC-1210A manufactured by ORIENTEC Corporation.

[0061] Grip interval (a): 10cm

[0062] Grip width (b): 6cm

[0063] Cloth load: After applying the load to 2.25kgf, restore it.

[0064] Tensile speed: 30mm / min

[0065] (3) Weight per unit area

[0066] Calculated from the mass per...

experiment example 1

[0072] Nylon 6 filaments with 22 decitex 24 filaments (TG47°C, TM225°C) are used for the warp, and nylon 6 filaments with 33 decitex 26 filaments (TG47°C, TM225°C) are used for the weft, and the taffeta is made by a water jet loom Silk fabric. The obtained fabric was refined and pre-set by the usual method, dyed and dried with a liquid flow dyeing machine, and Nikka Chemical Co., Ltd.’s Nikkasilicon DM-100E 1% and anionic surfactant were used as the modified silicone resin. The emulsion with 0.5% agent was processed by DIP-NIP method. After drying at 140°C, the calendering temperature was 160°C and the calendering pressure was 300kgf (=300×9.807N) / cm (roll width 160 cm, cloth width 150 cm, therefore P = 48 (t / cloth width 150 cm)), calendering speed 15 m / min hot calendering. The attached amount of the silicone resin was 0.8 wt%.

[0073] Regarding the properties of the obtained fabric, the cover factor was 1801, the degree of overlap was 0.80 in length and 0.50 in width, an...

experiment example 2

[0075] Nylon 6 filaments of 22 decitex 24 filaments (TG47°C, TM225°C) were used for the warp, and nylon 6 filaments of 33 decitex 26 filaments (TG47°C, TM225°C) were used for the weft, and the grid was produced in the same manner as in Experimental Example 1. Taffeta fabric and processing.

[0076] Regarding the properties of the obtained fabric, the cover factor was 1953, the degree of overlap was 0.85 in length and 0.60 in width, and the weight per unit area of ​​the fabric was 45 g / m 2 , the tear strength is 16N in warp and 16N in weft, and the air permeability is 0.8cm 2 ·Second. In addition, the air permeability after the oblique deformation measurement method is 0.9cc / cm 2 ·Second.

Abstract

Provided is thin lightweight woven fabric which is suitable for use as covering fabric for down wear, down jackets, futons, sleeping bags, etc. and which, even when subjected to bias deformation, can retain low air permeability. The present invention relates to thin lightweight woven fabric constituted of synthetic fiber multifilaments, characterized in that in a cross section of the warp or weft constituting the woven fabric, the degree of overlapping between adjacent groups of monofilaments is 0.6 or greater for either the warp or the weft and that the woven fabric has a basis weight of 15-50 g / m2. The invention further relates to sports clothing, ticking, and inner-bag woven fabric which are each obtained using the thin lightweight woven fabric.

Description

technical field [0001] The present invention relates to thin lightweight fabrics. More specifically, the present invention relates to a thin lightweight fabric for sportswear etc. which is lightweight and thin and maintains low air permeability even when deformed obliquely. Background technique [0002] The following Patent Document 1 discloses a water-repellent, calendered, low-basis-weight lattice fabric that is hardly deformed obliquely and has almost no air permeability as a fabric for airfoils. However, coating with synthetic resins such as urethane-based and acrylic-based resins reduces the deformation in the oblique direction, and the fabric becomes thick and poor in texture, making it difficult to apply it to clothing fabrics. [0003] In addition, the following Patent Document 2 discloses that the air permeability of fabrics is reduced by the presence of multifilaments composed of synthetic fibers of 28 dtex or less and monofilaments are arranged in two layers, and...
