Preferably, through the roller coat application of adhesive.Use Fig. 4 and Fig. 5, roller coat has been described.Through roller coat, the cylinder 15 of two heating is arranged in fabric 3 tops, and between the cylinder 15 of two heating with adhesive 13 fusings.Through the cylinder 15 of the heating of rolling, the adhesive 13 of fusing covers and is attached on the whole periphery of cylinder 15 of heating, and makes fabric 3 chargings.Warp yarns 3a through with the surperficial 5b of the back of the body contacts with weft yarn 3b, and adhesive 13 is shifted and is coated on warp yarns 3a and the weft yarn 3b.Control the amount of the adhesive 13 that applies through the interval between the cylinder 15 of two heating.The adhesive that does not shift and be coated on warp yarns 3a and the weft yarn 3b is still attached with the periphery of the cylinder 15 that heats, and through the cylinder 15 that rotates heating this adhesive is got back between the cylinder 15 of two heating.Therefore, be restricted with the opening 7 that does not shift and be coated to the adhesive coverage fabric 3 on warp yarns 3a and the weft yarn 3b.Therefore, can be easily the ratio of above-mentioned (aperture efficiency of adhesive phase 9)/(aperture efficiency of fabric 3) be controlled in the above-mentioned digital numerical value.
Preferably, the roller coat that uses the adhesive of viscosity between 1500 to 12000mPas to implement adhesive 13 applies, and this is because this adhesive can easily apply.According to the type and the roll coating apparatus of fabric 3 and adhesive 13, suitably select the charging rate of amount, heating-up temperature and the fabric 3 of coated adhesive 13.When application of adhesive 13, the rotary speed of the cylinder 15 of heating is preferably identical with the charging rate of fabric 3.In this case, can keep the supply of adhesive 13 and the balance between the consumption (coating), adhere on the fabric 3 thereby can limit adhesive pearl.
If adhesive is applied with pattern or after applying on the whole surface of film substrate, substrate and fabric dry method layer closed, then adhesive will be present in the space of the substrate of fabric split shed.Therefore, adhesive will be through the opening of fabric during layer closes, and adhesive will adhere on the loop yarn yarn on front surface one side.Therefore, the loop yarn yarn will hang down to the surface of fabric, and therefore the loop yarn yarn will be not easy to tangle with the suspension hook of engages male member.
In addition, if use T-mould mouth application of adhesive, adhesive will the MD direction (vertically) along fabric be coated on the yarn from the T-die lip the T-die lip zone that contacts with yarn continuously so.Therefore, can reach balance between consumption of the adhesive of T-die lip (coated weight) and the quantity delivered.On the other hand, in the T-die lip zone that the fabric opening passes through, in the open area, do not consume adhesive, the adhesive of therefore supplying with to the T-die lip will be above consuming.Therefore, will on the T-die lip, form adhesive pearl.In addition, in conjunction with the supply of adhesive, it is bigger that adhesive pearl will become, and when reaching a certain size, will adhere on the fabric.When layer closed the substrate rolling, the adhesive pearl that adheres on the fabric caused adhesion, and the productive rate of joint female member will reduce.In addition, multiple character will be unstable, like engaging force between joint female member and the engages male member and the interlaminar strength between fabric and the substrate.
On the other hand, as stated, according to the joint female member 1 that obtains through roller coat, the adhesive coverage opening 7 on warp yarns 3a and the weft yarn 3b is not shifted and is coated in restriction.Therefore, the restriction adhesive adheres on the loop yarn yarn 3c on front surface 5a one side of tangling with the suspension hook of engages male member 31 33, and the restriction adhesive pearl adheres on the fabric 3.Therefore; Although when with the joint female member that is obtained such as close through the dry method layer and compare; The amount of dry back adhesive is less; But the joint female member 1 through roller coat obtains will have the interlaminar strength that improves between fabric 3 and the substrate 21, and the engaging force that engages between female member 1 and the engages male member 31 will be higher also.In addition, because application of adhesive stably, so the interlaminar strength between fabric 3 and the substrate 21 and the interlocking intensity that engages between female member 1 and the engages male member 31 can be stable.In addition, through using roller coat, can use fabric with low area weight.
In addition, for roller coat, not only adhesive 13 is coated to warp yarns 3a and the weft yarn 3b adjacent with substrate 21, but also is coated on the warp yarns 3a and weft yarn 3b that opened in 21 minutes with substrate.Therefore, most of warp yarns 3a and weft yarn 3b can help bonding between fabric 3 and the substrate 21, and therefore can improve the interlaminar strength between fabric 3 and the substrate 21.Therefore, through using roller coat, can improve the reliability that engages female member 1 and can stably produce joint female member 1.
Can compatibly be used on the mating system of papery diaper, flooring material, clothes etc. according to joint female member of the present invention.
