Problems solved by technology

However, due to the characteristics of high rigidity, many knots, dryness and hairiness of flax yarn, the fabric has the following weaknesses: ① Due to the high price of pure linen raw materials, the weaving process is difficult and prone to breakage during weft knitting on a large circular machine. Problems such as holes, yarn breakage, cloth stripping and broken needles make the weaving loss too large, and the weaving loss can be as high as 20%, resulting in high cost; ③Due to the characteristics of flax raw materials, the fabric feels rough and rigid, and the flax knots and hairiness lead to obvious discomfort and itching when wearing, and the yarn has high rigidity, small breaking work, and high elasticity. Poor recovery, easy to wrinkle and pilling on the cloth surface, not washable, greatly reducing wearability and consumer satisfaction

Embodiment 1

[0071] This embodiment provides a kind of hemp polyester twisted yarn, the preparation method of this hemp polyester twisted yarn comprises the following steps:

[0072] Select 100% flax yarn (yarn count is 28Nm, 36Nm respectively), determine that the twist TPI of the flax yarn of 28Nm is 9.5+ / -2%, and the twist TPI of the flax yarn of 36Nm is 13.5+ / -2%, determine the twist direction of the single yarn linen as "Z" twist, and the twist direction of polyester twist as "S" twist;

[0073] Select fine-denier polyester yarn (the polyester yarn is 30D / 12F semi-dull polyester low-elasticity yarn, which is made of polyester chips, which is processed by high-speed spinning polyester pre-oriented yarn and processed by drafting and false twisting). Silk is false twist (can be considered as no twist);

[0074] After selecting the yarn, clean the machine before weaving to ensure that the yarn fly is removed on the machine, and then twist the above two yarns according to the following pro...

Embodiment 2

[0100] This embodiment provides a kind of hemp forging fabric, which is made by adopting the hemp polyester twisted yarn (36Nm linen / 30D / 12F polyester, the twist TPI of the twisted yarn is 12) provided in Example 1. Its preparation The method includes the following steps:

[0101] 1) Carry out pretreatment to hemp polyester twisted yarn, the technique of described pretreatment is as follows:

[0102] Put the hemp polyester twisted yarn (36Nm linen / 30D / 12F polyester, the twist TPI of the twisted yarn is 12) in a water bath at 100°C for 60 minutes; then place the cooked hemp polyester twisted yarn in a 4g / L In the softening agent solution (the softening agent used is JSS soft oil (Magnasoft JSS)), treat at 50°C for 15 minutes; then dehydrate, dry, control the moisture content to 12%, and wax during winding (the wax can control the content of tidal rate 12%);

[0103] 2) Woven cloth

[0104] a. On-machine inspection: use a large circular machine for weaving, control the machin...

Embodiment 3

[0120] This embodiment provides a kind of hemp forging fabric, which is made by using the hemp polyester twisted yarn (36Nm flax / 30D / 12F polyester, the twist TPI of the twisted yarn is 12) provided in Example 1. The preparation method comprises the following steps:

[0121] 1) Dyeing and pretreatment are carried out to hemp polyester twisted yarn, and the technology of described pretreatment is as follows:

[0122] The linen-polyester twisted yarn is conventionally dyed first, and then placed in a 4g / L softener solution, the softener used is JSS soft oil (Magnasoft JSS), and treated at 50°C for 15 minutes; then dehydrated and dried to control the content of The moisture rate is 12%, and the wax is passed during the winding (the moisture content can be controlled to 12% when the wax is passed);

[0123] 2) Woven cloth

[0124] a. On-machine inspection: use a large circular machine for weaving, control the machine speed to 16r / min, adjust the tension to 10cN, check the cloth s...

Abstract

The invention provides a hemp-terylene twisted yarn and hemp forging fabric made of same. The hemp-terelyene twisted yarn is formed when flax yarns and fine denier terylene filaments are twisted together; content of the flaxen in the flax yarns is 100%; numbers of the flax yarns are 28 to 36 Nm with twisting degree (TPI)of 9 TO 13.5; the fine denier terylene filaments are 30D / 12F semi-extinction terylene low stretch yarns; and the twisting degree (TPI) of the hemp-terylene twisted yarn is 7 to 13. The invention further provides a hemp forging fabric prepared by the hemp-terylene twisted yarn. Deficiencies of uneasy weaving of the flax yarns, existences of holes, breakage and fabric separation during the weaving can be overcome; and the fabric made of the hemp-terylene twisted yarns is advantaged by smooth surface, soft hand feeling, great draping and great contact coldness sense.

Description

technical field [0001] The invention relates to a hemp-polyester twisted yarn and a hemp-forged fabric prepared therefrom, belonging to the field of textile fabrics. Background technique [0002] Linen fabric is a traditional clothing fabric. The raw material of the fabric is natural and environmentally friendly, and the style is simple and elegant. Because the surface of the material is smooth and has cracks, it has a good luster. favored by foreign consumers. However, due to the characteristics of high rigidity, many knots, dryness and hairiness of flax yarn, the fabric has the following weaknesses: ① Due to the high price of pure linen raw materials, the weaving process is difficult and prone to breakage during weft knitting on a large circular machine. Problems such as holes, yarn breakage, cloth stripping and broken needles make the weaving loss too large, and the weaving loss can be as high as 20%, resulting in high cost; ③Due to the characteristics of flax raw mater...
