After the ramie yarns are supplied into the resin liquid tank 19, they are uniformly coated by the pickup roller 20. Table 1 shows the types of resin solutions used at this time. Wool yarn uniformly coated with a resin is heat-treated in the dryer (23). Heat treatment for 3 minutes at the hot air temperature 150 ℃ for the purpose of drying up to 25% by weight of the moisture content of the yarn yarn attached to the resin by the coating.

수지 코팅된 모시 원사는 열처리 공정 후, 원사 권취부 세퍼레이터(29)를 통과하고, 권취롤러(31)에 의해 원사빔(32)에 친수성 고분자 수지(18)를 포함한 모노필라멘트형 모시원사(30)형태로 권취된다. 상기 모노필라멘트형 모시원사를 경사 및 위사로 사용하여 직물지 폭이 60인치로 기계화 직조를 하였다.After the heat treatment process, the resin-coated ramie yarn passes through the yarn winding part separator 29 and the monofilament type yarn yarn 30 including the hydrophilic polymer resin 18 in the yarn beam 32 by the winding roller 31. It is wound up in the form. The monofilament type yarns were used as warp and weft yarns for mechanized weaving with a width of 60 inches.

표 1에 모시원사의 최약점 강도 및 직조 상태를 나타내었다.Table 1 shows the strength and weaving conditions of the yarn.

<비교예 1>Comparative Example 1

친수성 고분자 수지액 코팅을 하지않고 모노필라멘트형 모시원사만 경사 및 위사로 사용하여 폭이 60인치로 기계화 직조를 하였다. 표 1에 모시원사 강도 및 직조 상태를 나타내었다.Without the hydrophilic polymer resin coating, only the monofilament type yarn was used as warp and weft yarns, and the mechanized weave was 60 inches wide. Table 1 shows the yarn yarn strength and weave state.
