うな問題かあった。<Problems to be Solved by the Invention> Conventional molded products using nonwoven fabrics and thermoformed with a mold make good use of the isotropy with respect to external forces, which is a characteristic of nonwoven fabrics. had the following problems.
１）不織布自体の強力が不足するため強い力の加わる用
途に使用出来ない。1) Because the nonwoven fabric itself is not strong enough, it cannot be used in applications where strong force is applied.
２）不織布自体の作り方が、繊維の絡合やバインダーに
よる接着力によっている為、洗濯やその池の繰り返しの
曲げ力の作用により不織布の強力が低下したり、破壊さ
れたり４−ろ。2) Since the non-woven fabric itself is made based on the entanglement of fibers and the adhesive strength of the binder, the strength of the non-woven fabric may decrease or be destroyed by the bending force of washing or repeated washing.
３）ある程度の強力を得るため不織布がかなりの厚味の
あるものとなり、薄くて・強力のゐろ成形品を得る事が
難しい。3) In order to obtain a certain degree of strength, the nonwoven fabric must be quite thick, making it difficult to obtain a thin and strong white molded product.
本発明は上記の問題点を解決し、薄くてしかも形態安定
性及び強度的に浸れた繊維成形品を金型を用いた加熱成
形により製造することを目的とするしのである。The object of the present invention is to solve the above-mentioned problems and to produce a thin fiber molded article with excellent shape stability and strength by heat molding using a mold.

。However, in the present invention, when the knitted fabric is supplied to a mold and heat-formed, it is undesirable for fibers other than the binder fibers to melt or deteriorate significantly. It is desirable to select other fibers appropriately in relation to flow onset temperature or melting point.

ド型こ配置された複合繊維等を使用することができる。The binder fibers used in the present invention can be conventionally known binder fibers as they are, such as fibers made of a single polymer such as modified polyester, modified nylon, or polyethylene, and fibers that improve the strength of molded products. Composite fibers have a core-sheath structure in which a low melting point component is used as a sheath and a component with a higher melting point is used as a core, and a composite fiber in which a low melting point component and a high melting point component are arranged side by side. etc. can be used.

It is more than 0 double fingers, preferably 50 to 70% by weight. 3
If it is less than 0% by weight, the fusion properties between fibers or yarn structures in the final molded product will be poor, and the shape stability after molding will be reduced.

が使用されろ。The knitting yarn constituting the knitted fabric in the present invention may be composed of 100% binder fiber, but is usually used as a blended yarn of binder fiber and pond fiber. A core yarn in which the binder fiber is present more near the outer periphery of the kunbo yarn, a drawn yarn that seems to be a blend of both fibers, a spun yarn of a fiber other than the binder fiber, or a twisted filament with a spun yarn or filament of the binder fiber. Please use the one that was given.

由に１戊形てきるという特徴を有するものである。In the present invention, a knitted fabric is created using such a knitting yarn. In this case, the knitting structure of the knit fabric is not particularly limited, but in order to improve moldability with a mold, it is effective to use a knit fabric with an elongation of 30% or more, preferably 50% or more. This type of knitted fabric can be formed relatively uniformly even if it undergoes large deformation during forming, such as deep drawing of thermoplastic resin notebooks, and even thin fabrics can be freely shaped into one shape. It has the following.

できるものである。In the present invention, as a method for forming the knitted fabric using a mold, a thermoforming machine or the like that has been conventionally used for forming thermoplastic finger resistant materials or the like can be used. That is, it can be manufactured by feeding a knitted fabric onto a mold that is preset at a temperature that matches the flow start temperature or melting point of the Binoda fibers contained in the knitted fabric, and then holding it for a period of 1 to 30 minutes. It is.

とかできる。Here, if the set temperature of the mold is too high, fibers other than the binder fibers tend to melt or deteriorate, so the temperature must be set deeply. In addition, almost no compression force is required during shaping, and if the shape of the molded product to be obtained is simple, the knitted fabric is placed on a mold of a predetermined shape, and then It can also be manufactured by blowing hot air from one side to the other side.

性か向上する。<Effects of the Invention> In the present invention, since knitted fabric is used as the raw material for the molded product, its elongation deformation is large, and it is possible to perform deep drawing-like coloring along the mold and molding into complex shadow shapes. Moreover, the uniformity of the thickness of the final product is not impaired by the molding. In addition, the binder fibers in the knit constituent yarns that are softened and melted during molding firmly adhere and fix the fibers and threads as well as the structure itself after molding, which suppresses the elongation of the molded product and gives it a certain softness. However, the morphological stability is improved.
