Definitions

  • each male element of the male piece consists of a stem and a cap laterally expanded at the top thereof, and is composed of compo sitions of a first and a second polyamide polymers having different melting points. These polymers are formed in crystalline composition in the stem and in amorphous composition in the cap.
  • the stem consists of a core portion formed with the first polymer of lower melting point, and a sheath portion formed with the second polymer having a higher melting point.
  • the cap consists of a core and outer layer portions formed with the first polymer, and an intermediate portion of a second polymer sandwiched therebetween.
  • the present invention relates to an improvement of the male piece of the velvet type fastener, particularly it relates to an improvement of the male element provided with a laterally expanded cap formed at a top end portion of a stem projected upright from a base fabric of the male piece.
  • polyolefin or polyamide monofilament yarn have been preferably utilized, because of their desirable properties of elasticity, heat durability and strength, etc.
  • the strength of the connected portion between the cap and the stem of the male element is insufficient and, consequently, the cap is apt to be broken off from the stem after repeated utilization of the fastener.
  • the principal object of the present invention is to eliminate the above-mentioned drawback of the velvet type fastener of the latter type.
  • FIG. I is a schematic perspective view of an embodiment of a male piece according to the present invention.
  • FIGS. 2A 2D are enlarged side views of the male pieces according to manufacturing steps of the velvet type fastener of the latter type;
  • FIG. 3 is an enlarged longitudinal cross sectional view of a male element of a conventional fastener of the latter type for the purpose of comparison with the present invention
  • FIG. 4 is an enlarged longitudinal cross sectional view of a male element shown in FIG. 1.
  • the male piece is produced by the following steps: (1) a double woven fabric, wherein two base fabrics 2 are interconnected by connecting threads 1 made of monofilament yarn is produced; (2) the base fabrics 2 are separated each other by cutting the connecting threads 1 so that each separated base fabric 2 is provided with a plurality of upright monofilament piece 1 (3) the separated base fabric 2 is coated with a bonding resin so as to fix the upright monofilament piece I thereto, consequently material fabric is produced; (4) next, the material fabric is passed through a water bath so as to cool the material, and immediately afterwards the material is carried to a heat treatment process in which the tip of each upright monofilament piece is fused by applying heat energy rapidly while the remaining portion thereof is maintained in crystalline composition; (5) after this heat treatment the material is passed through cool water so as to solidify the fused portions of the material.
  • a plurality of male elements composed of a stem portion 4a and a fused tip portion 4b thereof, can be formed on the base fabric 2, so that the male piece is produced as shown in FIG. 3.
  • a pile knitted fabric can be utilized instead of the pile woven fabric.
  • this fused portion 4b has an amorphous composition. Consequently, it may be understood that the fused portion of the upright monofilament yarn of the male piece has an amorphous composition. As the tip portion is fused, this portion has a mushroom type shape expanded laterally. This portion is hereinafter referred to as a cap 4b, and the remaining upright portion of the monofilament yarn is hereinafter referred to as a stern 4a. As already illustrated, the cap 4b has an amorphous composition while the stem 40 has a crystalline composition. It must be understood that, there is not any critical boundary line between these amorphous compositions and the crystalline compositions.
  • this connecting portion is one of the weak points of the male element.
  • the microscopic observation of this portion was carried out. It was found that a certain number of male elements are provided with cracks formed in the boundary portion thereof. It may be interpreted that these cracks 5 are created according to the difference of heat-shrinkage between the cap and the top portion of the stem, effect of rapid heating and effect of rapid cooling. Therefore, if a strong shearing force is applied between an engaged male piece and female piece the above-mentioned cracks are expanded and finally in a certan number of male elements, the caps 4b are separated from the stems 40 thereof.
  • the tip of the core portion 6a and the tip of the sheath portion 6 are fused as shown in FIG. 4.
  • the configuration of the cap is composed of a fused core portion 6b and outer layer 60 and an intermediate fused portion 6d formed between the core portion 6b and the outer layer 6c.
  • polycapramide nylon 6
  • nylon 66 polyhexamethylene adipamide
  • These polymers may optionally comprise inorganic or organic materials of, for example, delustering agents, pigments, dyes, weather-proofing agents (ultraviolet ray absorbing agents), antistatic agents, plasticizers and flameretardant agents.
  • inorganic or organic materials of, for example, delustering agents, pigments, dyes, weather-proofing agents (ultraviolet ray absorbing agents), antistatic agents, plasticizers and flameretardant agents.
  • two of these polymers having different melting points are used and conjugately spun into sheat-core type yarn.
  • the difference of the melting point between the polymers composing the sheath-core type yarn is more than 20C, preferably from 40 to 60C. When the difference of the melting point is less than 20C, it is difficult to cover the subsequently fused portion with the firstly fused portion at the time of the heat treatment.
  • the cap cannot be in most cases normally formed, due to the fact that the amount of the fused polymer in the firstly fused portion becomes too large for the amount of the fused polymer in the subsequently fused portion.
  • homopolymers such as nylon 6 and nylon 66 may be used in combination with each other.
  • a known copolymerized nylon is used, as one of the two-component polymers, together with the above-mentioned homopolymer, or that polymers bearing therebetween the melting point difference of from 20 to 60C are selected from the various types of copolymerized polyamides and used as the two component polymers. in general.
  • low melting point polyamides of a two-component system such as nylon -nylon 66, nylon6-nylon 610, nylon 6- nylon 6T or nylon 66-nylon 610, and a threecomponent system such as nylon 6l0-nylon 6-nylon 66.
  • These two-component polymers can form the desired cap formation sufficient for practical use, if the difference of the melting point therebetween is less than 60C.
  • a monofilament yarn having a thickness in a range of 70 denier i000 denier, preferably 200 denier 800 denier is used. It is required to use the drawn monofilament yarn having crystalline composition. However, the thicker monofilament may be used according to the end use of the fastener if the weaving or knitting operation can be carried out. With regard to the cross-sectional shape of the monofilament yam, it is preferable to use a yarn having a circular cross-section wherein the core portion and the sheath portion have a concentric longitudinal axis.
  • the occupying ratio (in weight) of the core portion and the sheath portion in the monofilament yarn may be chosen in a range between /20 50/50.
  • Example A monofilament yarn of 300 denier was prepared by using in the sheath portion nylon 6 having a melting point of 2l5C and prepared by polymerization of e-caprolactam, and in the core portion copolymerized polyamide having a melting point of C and consisting of 52 parts of nylon 6 and 48 parts of nylon 66.
  • the melt spinning was carried out at 280C by means of an ejecting nozzle for conjugate spinning of sheath-core type yarn and the occupying ratio of the sheath portion and the core portion in the obtained yarn was in 25 75 by weight. Then, the yarn was drawn in a conventional manner.
  • a pile fabric was produced under the following conditions.
  • This resistance is referred to as a separation resistance (gICm) in the table.
  • Shearing resistance was measured by applying the following measured method. After firmly engaging the male piece with the female piece, a free end of the male piece and a free end of the female piece were gripped by a pair of grippers of a tensile test apparatus. In this test, the width of the sample pieces were 2 cm, respectively, the distance between the two grippers was cm, the length of engaging portion was 2 cm. The force which was required to separate the male piece from the female piece was measured by this tensile test apparatus. A shearing force of kg/cm was then calculated from the above-mentioned measured force. The abovementioned tests were also carried out after the male piece and the female piece were engaged and disengaged 3000 times.
