Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides f#
A special insertion method K11l is used.

Conventional methods for tightening knotted M1S products such as futons made of synthetic fiber staples include opening staple raw cotton in a carding process, spinning it into a web, and laminating or laminating this web into a predetermined thickness and shape. It is stratified and inserted manually or mechanically into the sides of futons, etc., and it cannot be said to be a method that requires a lot of labor and time. −
In the production of futons, shoes, etc. by the Manba craftsmen, a method is used in which 81s is blown into the side area that has been sewn in advance using an airflow using a blowing machine. This is an extremely interesting method of line entry in terms of work efficiency.

In recent years, a method using this air flow has been studied as a method for inserting lines into stuffed products made of synthetic fibers,
Publication No. 891 and Japanese Patent Publication No. 66-29666 disclose a method for making futons and the like by blowing nine fibers into side fabrics. However, the synthetic wire staples used in the normal carding process are generally highly entangled, and when the web or sliver on the top of the card is tried to be introduced into the side by airflow, it becomes a continuous 11 or a very large lump. Because it enters, the cotton does not reach the corner of the side fabric, and #I
This is undesirable because spots of large and small lumps are formed in the rejected product.

Synthetic delicate stable with a small opening SF or unopened chips can be easily put into KJI by air flow as a small cotton mass, but IaJll
Since the size of is not constant and its density 1 is not uniform,
When placed in a second layer, the hardness of the product will be extremely strong.
It becomes unsuitable as a plow product. Also special public service 1986-295
With No. 66, synthetic fibers with low Fi entanglement properties are opened with a card, etc., and the web is torn into small fiber lumps using a suction duct, taking advantage of the low entanglement properties. The method of injecting into the resin is reinforced, but in order to reduce entanglement, K and expensive silicone resins are used.
If the product is layered, there is a problem of increased cost, and if the entanglement is reduced by extremely reducing the number of crimps or shortening the fiber length, staples may be added to the # blown into the product. There are problems such as its bulkiness and low commercial value. Even more! 2! 91ajIIL is torn by the airflow, and the size is inevitably uneven, and the lack of uniformity becomes noticeable in products such as small futons of 41Klft.

In view of this situation, the inventors of the present invention have made extensive studies on a rational and economical cotton filling method for manufacturing stuffed products, and have developed the present invention.

That is, the object of the present invention is to form a small lump of synthetic fiber stable by using a carded docker in which a web non-forming area is provided on the surface and the web forming area is segmented, and the tJ - A new method for inserting cotton into ill##il products, which is characterized by blowing the cotton mass into the side fabric using a 9-ply.

The method of the present invention will be explained using the cotton carding machine shown in FIG. 1. In the normal cotton carding process, the yAM staple (1) is supplied from
The opened staples carried onto the cylinder (8) by the group of foot rollers (7) are transferred to the final card docker (4) to form a web layer with a constant thickness. This web pigeon is separated from the final card doff (4) by the fly comb (5) and the lattice (
6) To be carried upwards.

In the present invention, a carded transferr (4) in which a non-web forming area is provided and a web forming area is segmented is used as the carded transferr (4), and the spread staples carried onto the cylinder (8) are transported to the cylinder (8). Move only to the sectioned web forming area on the doffer (4). The web separated from the doffer by step 72 (: l-m t61) corresponds to both sides of each of the divided web forming areas. falls onto the lattice (6) as small cotton clumps (8).

The appropriate means for segmentation here refers to an ordinary card dot that has clothing on its entire surface, and in the area where the web is not to be formed, the resin trough is marked with a filling such as metal. or removing the staple, or even making a dossier from the beginning with a section without clothing, in order to prevent the staple from becoming trapped in this section.

The divided shape of the web forming area on the card dot surface is not limited to 41, but as an example, 1
Examples include those shown in Figures 12 to 114. The size of the web forming area and non-web forming area to be segmented is preferably one that satisfies the conditions of equations (11 to (6)) in relation to the fiber length (4) of the synthetic fiber stable used as raw cotton.

When C is set to 2d or more in 512, the quep separated from the final card doffer (4) will change direction of rotation of the doffer due to the action of the two lycombs (6), as shown in Figure 2. It can also be taken out as a small lump rolled in a cylindrical shape by rolling in the opposite direction.

In this way, the small cotton clumps of a certain size obtained from the carded roots incorporating the dots provided with the non-web forming area used in the present invention are individually and To be free to move... comes.

In Fig. 1, the small cotton lumps sucked from the suction duct leading to the blower are installed in the place following 72 Icomb (61 'JI' or following the lattice (6) K). It is discharged and can be blown into the side fabric of futon stuffed products.

The small cotton clumps produced by Card EliK of the present invention are uniformly opened and have a uniform size, and can be made into fine pieces by using a blower, but the cotton clumps as a whole are also uniform in size. It is a pervasive and extremely uniform gift. Furthermore, it should be noted that it has an extremely high bulk and compressive elasticity compared to a stuffed product made of ordinary carded web. In this card web 1
1 fiber is a fine lump with KM in one direction, but the stuffed cotton in the stuffed cotton product according to the present invention is made up of many small cotton lumps aggregated from all directions, and the fiber direction is also a fine lump with KM in one direction. Being facing K means being there.

The synthetic fiber staples used in the present invention include general synthetic fiber staples such as polyester, acrylic, and nylon, as long as they are applicable to the carding process.
Not particularly limited. It may also be a mixture of up to 50% cotton, rayon, acetate fat natural fibers, recycled fibers, etc.

Historically, it has been used as a stuffed cotton product to provide excellent bulkiness, bulk recovery, compression repulsion, and feather-like combs, with the number and crimp ratio, cut length, and smoothness imparted to the fiber surface. Various properties can be added, such as a composite structure for spiral crimp.

The fineness of the staple is preferably 8 to 20 denier from the viewpoint of bulkiness, compression repulsion, etc., but it is not limited to %, and from the viewpoint of heat retention, staples of 1 denier or less may be used alone or in combination. You can also do that.

In the present invention, when the small cotton lumps are conveyed and blown into the side of the stuffed product using a nine-tone accent, it is possible to use the blower or exhauster commonly used for -N. Small IaJl
In the general air blower 11, l is sucked in from a suction duct connected to the fan section, passes through the fan section, and is discharged from the outlet duct. At this time, if the discharge duct is connected to the ground pressure on the side of the stuffed product, the small lumps can move freely and be evenly blown into the side ground. Depending on the structure of the fan section or the number of fans in one row, the shape of the cotton clumps passing through the fan section may change to some extent. However, the deformation tends to make the cotton clumps smaller, and the uniformity of the stuffing in the product is further improved.

Note that in Q11 of the present invention, the carding process and the cotton product processing by air fiK may be continuous, but it is also possible to separate the process and store the small web cotton mass.

The present invention will be explained below with reference to Examples.

Example 1 An oval fiber staple as shown in ^11iK is made into opened cotton through a normal carding process or a carding process of the present invention as shown in 142fR, and this opened cotton is made into M200.
