The present invention is made of a synthetic resin that is particularly suitable as a secondary base fabric, which has increased adhesion with latex, and has also improved the corrosion resistance, bacterial adhesion, and non-uniformity of the product that were observed in conventional natural jute. The present invention relates to a method for manufacturing a carpet base fabric. Traditionally, tufted carpets are made of jute or
A woven fabric made of PP flat yarn plain weave is used as the primary base fabric, pile is flocked to this, and a woven fabric made of Jute plain weave is used as the secondary base fabric and the two are bonded together with latex. Manufactured by. However, juute, which is the material for the secondary base fabric, is a natural product and there are concerns about its supply, and there are various problems such as corrosion resistance, lack of water resistance, adhesion of bacteria, and non-uniformity of the product. There was a demand for a change to materials. Therefore, polypropylene flat yarn cloth and cotton, which are often used as the primary base fabric,
It has been proposed to use woven fabrics using spun yarns such as ester, rayon, PP, acrylic, etc., and woven fabrics using defibrated yarns, but in both cases, adhesion to the latex layer may occur due to insufficient napping on the surface of the woven fabrics. There are problems such as poor quality, the stiffness of the woven fabric itself, and high price, and as a result of intensive studies to solve these problems, the present invention was arrived at. The gist of the present invention is that the fineness with napping is from 1000 to
4000 denier yarn is used as weft, fineness is 300~
1000 denier, width (W) to thickness (T) ratio (W/
A thermoplastic resin flat yarn with T) of 20 to 75 is used as the warp yarn, and the weft yarn is woven at a rate of 6 to 14 yarns/inch.Then, this woven fabric is woven with an auxiliary needle cloth for raising with a weak needle point torque. Using a rolled clothing roll and/or a sandpaper napped roll, the woven fabric is woven with a touch bar at an acute angle in the case of the above clothing roll and at an acute angle in the case of the sandpaper napped roll.
A method for producing a carpet base fabric, characterized in that the fabric is brought into contact at an angle of 10 to 120° and raised at a ratio of roll speed (RV) to woven fabric speed (CV) (RV/CV) of 5 or more. First, the method for manufacturing a carpet base fabric of the present invention will be explained with reference to the drawings. FIGS. 1 and 2 are plan views showing examples of carpet base fabrics produced by the method of the present invention, respectively. The base fabric in FIG. 1, two polypropylene flat yarns are leno-woven as warp threads 2 and then brushed, and the base fabric shown in Figure 2 is made by plain weaving using the weft threads 1 and warp threads 2 and further brushed. It will be done. Note that if a defibrated yarn with napping is used for the warp, fiber separation problems will occur during the manufacturing process. The yarn used as the weft in the present invention may be a fibrillated yarn, a spun yarn, etc. as long as it is a 1000 to 4000 denier yarn with a large number of naps, and its material may be any material as long as it has a melting point of 140°C or higher, but especially A defibrated yarn made of polypropylene and having naps is suitable. In the present invention, it is important to use a yarn with a large number of naps as the weft yarn.
This is because even if the woven fabric is raised as described below, good napping cannot be obtained on the surface of the woven fabric, and the adhesion to latex becomes very poor. If the woven fabric is forcibly raised in order to obtain a raised appearance, there are problems in that the raising cost becomes very high and the physical properties of the woven fabric, especially its strength, deteriorate significantly. Also, the fineness of the yarn used is
The optimal value is 1000 to 4000 denier; if it is less than 1000 denier, there will be problems with the strength of the woven fabric, the thickness of the woven fabric, the amount of raised fabric, etc. If it exceeds 4000 denier, there will be problems such as weaving troubles and increased costs. For the same reason, a good number of implants is 6 to 14 per inch. In addition, the warp used in the present invention is made of thermoplastic resin, preferably polypropylene, and is stretched 5 to 7 times.
Flat yarns with 5-12% relaxation and low shrinkage are used. Naturally, the conditions for film formation, stretching, etc. may be normal. The fineness, width, and width-to-thickness ratio of the flat yarn used are important; the fineness is 300 to 1000 denier, preferably 300 to 500 denier, the tape width is 0.8 to 2.0 mm, and the ratio of width W to thickness T is W/T. A good value is 20-75, preferably 35-60. If the fineness above is less than 300 denier, it will become too thin.
The strength of the product is low, and it cannot withstand the post-processing of paper making and woven fabric raising processes, so even if it could be processed, the strength of the product would be low. If it exceeds 1000 denier, there is a cost problem, but it is also difficult to perform weaving such as karamiori, the warp density increases, and the weft part, which is the adhesive part, is difficult to expose on the surface of the woven fabric, resulting in poor adhesion. . If the width exceeds 2.0 mm, the leno weaving will be poor because the width is too wide, resulting in poor weaving properties, and furthermore, the thickness will be thin, resulting in fiber separation problems during weaving. Width is 0.8
If it is narrower than mm, it is almost impossible to form a flat yarn, but because the thickness becomes extremely thick, the warp yarns will not be rounded by weaving, and the warp portion will be the same as the tape width, and the warp density will increase on the surface of the woven fabric, resulting in a bonded area. This has the disadvantage that the weft portion is reduced, resulting in poor adhesion.
Moreover, if W/T exceeds 75, fiber separation trouble will occur in the manufacturing process, and if it is less than 20, the weft portion of the bonded portion on the surface of the woven fabric will decrease, resulting in poor adhesion. There is no problem with weaving carried out by the method of the present invention, whether it is leno weaving or plain weaving, but leno weaving using warp yarns has fewer stitches and there is no problem with stitches even if the woven fabric is raised after weaving. It is preferable because there is no. Further, the number of weft threads is 6 to 14/inch, preferably 8 to 12/inch. If the number is less than 6, there will be a problem with the adhesion of the woven fabric due to the small number of weft yarns that are the adhesive part, and if it exceeds 14, problems will arise in the weaving process and cost issues, although the adhesion will not be a problem. The woven fabric raising performed in the present invention is necessary to obtain sufficient adhesion, and the counter pile roll and the pile roll, which rotate on their own axis and are made of curved needle cloth with short needle height and strong needle tip torque, are used as a set. Good napping can also be obtained by using conventionally known hydraulic or electromagnetic napping machines, in which about 12 sets are installed on the outer circumferential surface of the cylinder in which it revolves, but in this case, the processing speed is slow. Slow, the machine price is expensive, the diameter of the cloth roll cannot be increased due to the machine mechanism, and it revolves and rotates at high speed, so the material is 3m.
There are problems such as difficulty in manufacturing a wide machine that is wider than the width of the machine. Therefore, a method of bringing the material into contact with a raising roll using a sandpaper raising roll or an auxiliary needle cloth for raising described below, or a method of using a combination of these methods to raise the raised fabric can quickly and easily yield a good raised woven fabric. Therefore, it is preferable. That is, when using a raised sandpaper roll, wrap relatively coarse sandpaper around the rotating roll and bring the cloth into contact with it at a contact angle of 10° to 120°.
The ratio RV/CV of the napping roll speed (hereinafter referred to as RV) and cloth speed (hereinafter referred to as CV) is 5 or more, especially 10 to
A method of contact raising with 100% is preferred. If the above contact angle is less than 10°, no napping will occur, and if it exceeds 120°, napping will occur, but the strength will be extremely reduced and the contact resistance will increase, making it difficult to adjust the tension of the woven fabric in contact. Trouble occurs when the woven fabric gets wrapped around the napping roll. A feature of raising a raised woven fabric using the sandpaper method is that a large number of naps with relatively short pile lengths are generated. In this case, the smoothness of the surface of the woven fabric is important, and if the smoothness is poor, uneven napping tends to occur and the strength of the woven fabric decreases. In particular, there is a problem in that the flat yarns of the warp are severely damaged, resulting in a large decrease in strength in the longitudinal direction. Therefore, as a raising method, as shown in the side view of the process in Figure 3, instead of the raising cloth normally used in the raising machine, straight needles or curved needles with relatively weak needle point torque, which are used as auxiliary cloth for raising, are recommended. Needle cloth for splitting hair 3
A cloth for handling wool is wound around a rotating roll 4 to form a raised roll, a woven fabric 5 is brought into contact with the raised roll, preferably with a touch bar 6, and the cloth is brought into contact with the touch bar 6 at an acute angle to determine the ratio of RV and CV.
It is preferable to use a method in which the hair is raised with a value of 5 or more, particularly 10 to 100. Conventionally, there was no concept of napping in cloth for splitting wool or clothing for handling wool, and these were simply used for splitting and handling pile yarns, and the use in the napping method was the subject of the present inventor. These were achieved as a result of intensive research aimed at achieving the necessary characteristics of carpet base fabrics. As a result, woven fabrics that use raised yarns as wefts can easily develop the raisedness needed to provide adhesive properties as carpet base fabrics without damaging the warp threads or reducing the strength of the woven fabric itself. This made it possible to easily manufacture a machine with a wide width of 4 to 5 m, which is necessary for carpet base fabrics, in terms of mechanical structure, and also solved problems in terms of manufacturing equipment.
If the needle cloth used has a strong needle tip torque, the fabric may be damaged, and if the contact time between the needle tip and the cloth is slightly adjusted incorrectly, and the needle cloth enters the weave even slightly, the fabric may be damaged. do. The method of the present invention uses a mechanism in which the needle tip torque is weakened and the needle tip escapes from the cloth while raising the cloth. In addition, contacting the woven fabric with the napping roll at an acute angle using a touch bar prevents the fabric from being damaged during the process, as in the case of using needle cloth with strong needle point torque, if the fabric is brought into contact with the napping roll at an acute angle. This is to prevent this. Furthermore, RV/CV is preferably 5 or more.
A value of 10 to 100 is good, and if it is less than 5, sufficient napping cannot be obtained. It should be noted that the velocity directions of RV and CV are preferably opposite directions, and in this sense, it may be better to express that RV/CV is -5 or less, but the minus sign will be omitted hereinafter. Although one stage of raising as described above is enough, it is preferable to minimize the RV/CV of each stage and complete the raising with two or more stages in terms of uniform raising and fabric strength. . In addition, when the nap is raised using the auxiliary cloth roll for raising, a nap with a relatively long pile and a small number of naps can be obtained. Therefore, in order to give the nap a long and short distribution, the above-mentioned sandpaper roll nap is used in combination. In other words, in the first stage, a light sandpaper is used to create a nap with a large number of naps and a short pile, and then in the second stage, an auxiliary needle cloth roll for napping is used to create a long nap, which is a practical method for carpeting. Base fabric can be manufactured. On the other hand, the carpet base fabric produced by the method of the present invention is also useful as a primary base fabric, and is particularly suitable as a primary base fabric for fine gauge carpets, and is also useful for preventing greening because it is raised. It is. Examples 1 to 4, Comparative Examples 1 to 6 Polypropylene (MFI = 3.5 g / 10 min) film was stretched 6 times and relaxed by 10%, then defibrated with a needle blade roll and brushed to create defibrated yarns of various deniers. Polypropylene as weft (MFI=3.5g/10min)
Two flat yarns of various widths and deniers, which have been stretched 6 times and relaxed by 10%, are leno-woven as warp yarns, and as shown in Figure 3, a cloth roll wrapped with auxiliary cloth for napping is rotated in the opposite direction to create two stages.
