Abstract

PURPOSE:Short cut fibers of specific length and thickness are directly admixed to a flexible synthetic resin, made into sheets, then the surface of the sheets is ground to give the titled sheets which are excellent in their wearing properties and surface-treatable. CONSTITUTION:A flexible synthetic resin, e.g., a composition containing 100pts. wt. of a vinyl chloride resin, 70-100pts.wt. of a plasticizer and 2-3pts.wt. of stabilizers, is mixed with short-cut fibers of 0.5-2.0 deniers and 1.5mm. or shorter length in a range of from 30 to 100PHR. Then, the resultant composition is milled or extruded into sheets, then the surfaces are ground to gig the short-cut fibers which are uniformly dispersed in the sheet. When the above-stated resin is combined with a foaming agent in addition, then foamed after sheet formation, a forming sheet with suede-like surface soft and warm, quite free from synthetic resin feel is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides molding sheets 1-
It is related to.

Conventionally, this type of molding sheet has been produced by applying an adhesive onto the surface of a flexible sheet, and then dropping a tow formed in advance to a certain size, and simultaneously applying adhesive on the front and back sides of the sheet. By applying a different current of 4M from both sides and planting the tows one by one in a straight ☆ shape on the adhesive layer, the suu I-
I felt a deep sense of luj/, :L't. However, the forming sheet processed by this method has the following problems:1. :
Because 1-U is flocked one by one to the adhesive layer, it has poor abrasion resistance, and the tow may fall off when cleaning the surface, and when molding. The adhesive layer on the centrifuged part may peel off or crack, resulting in 1112 hairs, which can cause eye problems when used for molding, and the flocked surface produces a suede tedge, so the surface cannot be embossed or printed. It was difficult to Furthermore, in terms of the process, rolling → adhesive application → flocking → surface treatment → grinding, etc. are required, resulting in a product with a poor yield, although the suede feel is unpleasant. The current situation is that it has many drawbacks, such as higher costs.

The present invention has been made in order to overcome the drawbacks of the prior art as described above. Specifically, the present invention has been made to solve the drawbacks of the prior art. Short wear with a length of 1.5 mm or less is 30 to 100 P LI R
This is mixed directly into a sheet within the range of 100% by weight, formed into a sheet by rolling or extrusion, and the resulting warped surface is not ground, thereby raising the short am mixed uniformly into the sheet.

1111-J to raise the short fibers (short fibers) uniformly kneaded in the sheet 1. The purpose is to provide a sheet for molding with a new suede-like surface that is soft and loose without any resin feel, and is made of soft vinyl chloride resin, such as vinyl chloride resin 100, which is a conventionally known soft 711 synthetic resin.
70 to 100 parts of plasticizer, 2 to 3 parts of stabilizer, and 3 to 5 parts of foaming agent, thickness 0°5 to 2.0 denier, length i , short fibers (tow) of 5 mm or less are mixed 30 to 1001) l-I R,
The II stretching method involves grinding the surface of the sheet after processing it using an extrusion method.
Because it is kneaded uniformly, it creates a raised effect and gives the suede feel. Furthermore, the surface is treated with polynisfur-polyurethane type surface treatment! 1! If you apply a double coat of the agent (Hanitan 529, Hanitan 5301 Honey I-S 659 manufactured by Honey Kasei Co., Ltd.), the napping surface itself will become more flexible, and the surface will have an even better surface. It gives a feeling.

Class 11 fibers are synthetic fibers (tow) such as nylon, polyester, and rayon, or human-made fibers (tow) such as cotton, linen, and wool.
: The length is 0.5 to 1.5 mm, the thickness is 0.5 to 2.0 denier, and the mixing ratio is within the range described above. - can create a loose suede feel. In other words, the quality is preferably 1.5 mm or less; if it exceeds this, one or two pieces will wrap around each other during kneading and it will be difficult to knead uniformly, and the physical properties and surface of the sheet after rolling will become rough, resulting in puffiness. Even with grinding such as
This results in a poor feeling of relapse. In addition, if the thickness is less than 0.5 denier, it will be difficult to raise the hair, and if the thickness is less than 0.5 denier,
If the denier is exceeded, the surface may become bumpy, making it unsuitable for use as a final product. Furthermore, in the blending ratio, 30 P
If it is less than 100 Pl-IR, the degree of napping is poor and an excellent suede feel cannot be obtained, and if it exceeds 100 Pl-IR, crosstalk becomes severe and sheet processing becomes difficult.

Examples and comparative examples of the present invention are shown below.

Unlike the conventional method of gluing and flocking the adhesive layer one by one on the surface of the sheet, the short fibers (tow) are kneaded into the white of the sheet in advance. It has excellent abrasion resistance when removing hair, and the suede surface will not be damaged by washing etc. Also, compared to the flocking sea 1-, you don't have to worry about the brushed hair getting crushed! It is easy to print or emboss embossed grains (before cutting).Furthermore, when using this for molding, it is recommended that the thickness be 0.5 = 2.0 denier and i, 5mm or more F. 61 is uniformly added to the fat (because of this, the molding rate is 2 to 3 times higher). 1II 2.0 denier r and a length of 1.5n+m or less 1-U is 30 to 1
After mixing in 00Pl-IR and processing into a sheet by rolling method or extrusion method, foaming was performed in a foaming furnace.
In the case of J3, which is a foamed sheet for straight I-do molding made by grinding the surface, foaming occurs also around the short fibers, and forms a path that communicates with the foaming formed between the resin layers. It can be printed with moisture permeable material.

Also, from a process perspective, the present invention uses rolling and grinding as the main processes, so compared to conventional products, the steps of adhesive application and flocking can be omitted. It is possible to commercialize the product. Moreover, the first aspect of the present invention is
This makes it possible to perform various surface treatments.
