摘要:
A water resistant slide fastener, comprising: a pair of stringer tapes (14,16) each having first and second opposed surfaces (18,20) said stringer tapes (14,16) being positioned substantially parallel and side-by-side so as to provide said stringer tapes (14,16) with inner and outer edges; a series of gripper elements (22) positioned along said inner edges for releasably securing said stringer tapes (14,16) together; and a water resistant layer (26) on at least one surface of said first and second surfaces (18,20) and overlying said inner edges and said series of gripper elements (22), wherein said water resistant layer (26) comprises a polyurethane film having a multilayer structure including an inner layer (60) arranged facing said stringer tapes (14,16) and having a first Shore A hardness, and an outer layer (62) having a second Shore A hardness, wherein said second Shore A hardness is greater than said first Shore A hardness.
摘要:
A water resistant slide fastener (10), including a pair of stringer tapes (14, 16) each having first and second opposed surfaces (18, 20) and each having a series of gripper elements (22) positioned along edges of said first surface (18); and a water resistant layer (26) on said second surface (20), wherein said water resistant layer (26) has an adhesion to said stringer tapes (14, 16) of at least about 61b/in.
摘要:
A fluid-tight slide fastener comprises a pair of slide fastener halves (10, 10; 20, 20) each including a support tape (11, 12), a row of continuous coupling elements (12) extending longitudinally along the inner edge of the tape (11, 21) on one side thereof, and an elestomeric sealing member (15) overlying on the other side of the tape (11, 21). The tape (11, 21) has a longitudinal ridge (18', 28) substantially defining the inner edge and supporting the row of coupling elements (12) laterally longitudinally by means of stitching threads (14). A portion of the threads (14') is disposed adjacent to the ridge (18', 28) to prevent the latter from moving remotely from the coupling elements row (12) for thereby supporting the ridge intimately enough to ensure the abuttment of opposed sealing edges (16) of the tapes when the fastener halves are coupled together.
摘要:
fiuid-tight slide fastener (10) is disclosed which comproses a pair of stringer tapes (11. 12) each having an inner edge region (19), an outer edge region (17) and a stretchable region (18) intermediate between the two edge regions (19, 17) which are non-stretchabie. The intermediate stretchable region (18) is provided to yieldingly take up transverse stresses which would otherwise act upon the inner edge region (19) to split apart the fastener halves and produce leakage therethrough.
摘要:
a fluid-tight slide fastener stringer (10) comprising a support tape (11) made of a fluid-tight soft material, and a row of discrete coupling elements (17) mounted on the tape (11) along an inner longitudinal edge portion (12) thereof. Such tape margin is folded so as to provide therealong a contact portion (13) engageable with a corresponding contact portion (13') of a like companion stringer (10') to effect a fluid-tightness between the two stringers (10,10'). In order to absorb or reduce undue stress exerted on the individual coupling elements (17), each coupling element (17) has a slot (21) extending parallel to the general plane of the stringer (10) transversely through the whole width of a coupling head portion (19) and also extending longitudinally of the same coupling element (17) through the coupling head portion (19) into a base portion (18).
