Abstract

PURPOSE: A manufacturing method of a compressed material of non-woven fabric for a visor of a hat and a size tape which is characterized by being light and having excellent air permeability, adherent capability, marketability and tensile strength is provided. The non-woven fabric is obtained by hardening cotton and a binder. CONSTITUTION: A compressed material of non-woven fabric for a visor of a hat and a size tape is obtained by the steps of: mixing chemical fiber cotton with natural cotton in a weight ratio of 7:3 to manufacture mixed fiber cotton; making absorbed an acrylic binder into the mixed fiber cotton in a weight ratio of 1:3; and then compressing and heating the cotton.

Description

Method for Making Nonwoven Fabric for Cap Core Material {Method for Making Compressed Nonwoven Fabric of Cap Interlining}

The present invention relates to a method for manufacturing a nonwoven fabric press material of the core material of the brim or size tape (size tape).

The brim of the hat consists of a core material and an outer material. The core material is usually molded from a synthetic resin such as PVC, PE, or PP. In addition, the size tape is sealed inside the bottom circumference of the hat and determines the size of the hat as well as the core material. The size tape is also made of the same material as the core of the hat visor, but is very thin. The hat brim core material of the existing material has not only a small weight, but also difficult to pass the sewing needle during manufacturing, and friction heat with the sewing needle occurs, which causes the material to be exposed to the outside of the outer melt. In addition, the size tape of synthetic resin material has a weak tensile strength, so the length and contraction occurs when sealing, so the size of the hat is not constant, and the thickness is thin, so workability is low. Increasing the thickness in order to improve the tensile strength and workability lowers the flexibility of the hat and increases the weight. The cap rim core material and size tape of synthetic resin have a smooth surface and have different physical properties from that of the outer fabric, so it is very difficult to sew because there is no adhesion with the outer material, and even the finished product flows with each other without close contact with the outer material.

An object of the present invention is to provide a new material of the hat visor or size tape in order to solve such a defect of the synthetic resin material.

The core material of the hat visor or the material of the size tape should be lighter in weight, have adequate tensile strength, flexural strength and thickness, and have good adhesion to the outer fabric. Therefore, it is a technical problem to make the fiber as a base material, but to harden to suit the intended use and to form the desired shape.

The present invention is a method of forming a nonwoven fabric compact by absorbing a binder in a mixture of chemical fiber cotton and natural cotton.

This will be described in more detail. Chemical fiber cotton and natural cotton are mixed in an increase ratio of 7: 3 to make mixed fiber cotton. The mixed fiber wool is mixed with a curing agent in a weight ratio of 1: 3, absorbed, and heated by pressing at a temperature of 200 to 300 ° C. to form a non-woven fabric of a predetermined thickness. A nonwoven fabric compacted to a predetermined thickness is cut into a desired shape to produce a core material or size tape of a hat visor. As the curing agent of the present invention, an acrylic binder is most suitable. Other types of hardeners are also available. Chemical fiber cotton is low in tensile strength but inexpensive, so it is based on chemical fiber brush, and natural cotton is mixed to ensure tensile strength and increase texture and adhesion. Increasing the mixing amount of natural cotton increases the cost, so it is appropriate to make the weight ratio of chemical fiber cotton and natural fiber cotton 3: 1. Acrylic binder is evenly sprayed and absorbed into the mixed fiber cotton mixed to a certain thickness, and then compressed by heating with a compression roller, the mixed fiber cotton absorbed by the acrylic binder is cured to form the core material of the hat visor or the nonwoven fabric compressed material of the size tape. .

Nonwoven fabric compression material of the present invention is only half the weight compared to the synthetic resin of the same volume and excellent breathability and adhesion. If the weight is reduced to 1/2, the weight of the hat naturally decreases and the merchandise is increased. In addition, the molding of the present invention is because the cotton and binder is cured, the non-woven fabric is excellent in the bonding strength of the fiber structure as the excellent bonding strength and excellent adhesion to the outer fabric fabric and the sewing work is extremely easy and the core material and the outer fabric is sufficiently close after sewing. . In addition, because it is light in weight and excellent in tensile strength, it is also suitable as a material of size tape with moderate thickness and no deformation of length.
