example 1

[0023] Use semi-gloss polyester compound as raw material under spinning temperature 290° C. and spinning speed 3000 meter / min through 144-hole Y-shaped cross section spinning jet to make partially oriented yarn (POY) of 125 d / 144 f, the POY than passes the texturing process to obtain the draw textured yarn (DTY) of 75 d / 144 f with Y cross section under filament speed of 600 meter / min.

[0024] Use the DTY of 75 d / 144 f with Y cross section as warp and weft yarn through 1 / 1 plain stitch weaving with warp density of 148 filament yarn / inch and weft density of 108 filament yarn / inch to produce gray fabric which, after scouring and dyeing process, is processed by water repellent finish in five lots with following formula: [0025] Acetic acid 1 ml / l [0026] Ciba INVADINE PBN 5 ml / l [0027] Ciba OLEOPHOBOL 7690 40 g / l [0028] Setting temp.: 170° C.×45 seconds

[0029] Then the fabric is processed by KUSTER PRESS at 160° C.×15 yd / min, 100 kg / m2, and the analysis of the hydrostatic pressure resistan...

example 2

[0031] Use polyester DTY of 100 d / 288 f as warp yarn and filament of 75 d / 96 f as weft yarn all of which have cross-shaped cross section, apply 1 / 1 plain stitch weaving method with warp density of 144 filament yarn / inch and weft density of 112 filament yarn / inch, the gray fabric processed by scouring and dyeing finish and then treated by water repellent finish in five lots with following formula: [0032] Acetic acid 1 ml / l [0033] Ciba INVADINE PEN 5 ml / l [0034] Ciba OLEOPHOBOL 7690 50 g / l [0035] Setting temperature: 170° C.×45 seconds

[0036] Then the fabric is processed by KUSTER PRESS at 160° C.×15 yd / min, 100 kg / m2, and then test and compare the hydrostatic pressure resistance after 25 times of washing. The results are shown in Table 1 which shows apparently that when the polyester DTY with cross-shaped cross section is used as weft yarn, and makes up more than 30% (in this example of embodiment the ratio is 37%) of the yarns of the fabric, a satisfied hydrostatic pressure resistan...

Abstract

A moisture-permeable waterproof high density fabric made of polyester filament yarn with filament size of 0.2˜0.8 denier per filament (dpf) and with cross section having at least three grooves or recessions formed as Y-shaped, cross-shaped, or W-shaped cross section, or with cross section arranged as distinctive shape of Y-shaped, cross-shaped, or W-shaped cross section at different section of the filament yarn; the fabric is manufactured by high density weaving method, and processed by water repellent and hot press finish after dyeing processing through which to obtain a moisture-permeable waterproof fabric with property of hydrostatic pressure resistance higher than 700 mm H2O and wash ability better than that of the conventional woven fabric made of polyester filament yarn having round cross section, as well as better reproducibility without the need of coating or laminating processing.

Description

BACKGROUND OF THE PRESENT INVENTION [0001] 1. Field of the Present Invention [0002] The invention relates to a high density moisture-vapor permeable and waterproof fabric, particularly the fabric is made of polyester filament yarn of 0.2˜0.8 dpf and with which cross section is at least formed with three grooves. [0003] 2. Description of Prior Act [0004] Conventionally, based on the method of producing a moisture-permeable waterproof fabric can be classified into three types of coating, laminating and high density weaving. An example of coating type was disclosed on Japan Patent Publication No. 10-251976 which concerned an invention embodied by applying continuous or non-continuous coating of chemicals on woven fabric to form a coating film on the surface of the woven fabric. As for the laminating type, known as the transfer coating type, an example was disclosed on Japan Patent Publication No. 2002-030574 which concerned an invention embodied mainly by coating polyurethane (PU) on r...
