Problems solved by technology

And the present invention utilizes PLA colored filament to interweave with colored real silk, and PLA filament is weft direction, and real silk is radial direction, and organization is simple twill weave or satin weave, has nothing special with other fiber in weaving process, but in tie In the production process, because the heat resistance of PLA filament is quite different from that of real silk, there is a big problem in the ironing and shaping process. If it is not handled properly, it will cause uneven shrinkage and lead to deformation of the tie.

Embodiment 1

[0013] In this example, 75DPLA / 60S silk is interwoven into a twill tie fabric, and then it is pre-set at a temperature of 120°C for 40s. Through this pre-setting, the dimensional stability of the PLA fiber is strengthened; and then it is pre-shrunk on a pre-shrinking machine. Treatment, the temperature is 120°C, the time is 50s, the pre-shrinkage rate is 12%, so that it is fully pre-shrunk, and it will no longer shrink during the later tie ironing and shaping process; then carry out nano-finishing, the nano-finishing agent is 2g / L, The temperature is 105°C and the time is 40s to improve the stiffness of the cloth surface caused by pre-setting and pre-shrinking.

Embodiment 2

[0015] In this embodiment, 150DPLA / 40S silk is used to interweave satin tie fabric, and then it is pre-set at a temperature of 130°C for 50s. Through this pre-setting, the dimensional stability of the PLA fiber is strengthened; Shrinkage treatment, temperature 130°C, time 40s, pre-shrinkage rate 10%, so that it can be fully pre-shrunk, and no longer shrink during the later tie ironing and setting process; then carry out nano-finishing, nano-finishing agent 3g / L , temperature 110 ℃, time 30s, improve the stiffness of the cloth surface caused by pre-setting and pre-shrinking processing.

Embodiment 3

[0017] In this example, 150DPLA / 40S silk is interwoven into a satin tie fabric, and then it is pre-set at a temperature of 125°C for 60s. Through this pre-setting, the dimensional stability of the PLA fiber is strengthened; Shrinkage treatment, temperature 125°C, time 80s, pre-shrinkage rate 15%, so that it can be fully pre-shrunk, and no longer shrink during the later tie ironing and setting process; then carry out nano-finishing, nano-finishing agent is 1g / L , temperature 115 ℃, time 50s, improve the stiffness of the cloth surface caused by pre-setting and pre-shrinking processing.

Abstract

The invention discloses a processing method of polylactic acid fiber-silk interlaced necktie fabric which adopts polylactic acid fiber and silk to interlace and prepare simple twill or satin weaves. The processing method is characterized in that the 75-150D of polylactic acid fiber filament is used as weft and the silk as warp is used as warp to interlace, then presetting is performed at 120-130 DEG C for 40-60s, then preshrinking is performed at 120-130 DEG C for 40-80s with the preshrinking rate of 10-15%, and then nano-finishing is performed by using 1-3g / L of nano-finishing agent at 105-115 DEG C for 30-50s. The invention resolves the process problem of using core filament- silk interlaced fabric to prepare necktie, reduces the process cost of silk necktie and is characterized by gorgeous colour, soft hand feeling, and good elasticity and drapability.

Description

technical field [0001] The invention relates to a processing technology of tie fabric interwoven with polylactic acid fiber and real silk, belonging to the technical field of textile processing technology. Background technique [0002] Polylactic acid fiber (PLA) is made of corn, wheat and other starch-containing raw materials through fermentation into lactic acid, and then polymerized and spun. It not only has excellent physical properties and wearability, but also has biodegradable properties. It is a new type of environmentally friendly fiber that can be completely recycled naturally, and it is also the only synthetic fiber that does not rely on petroleum resources. [0003] PLA fiber has unique physical and chemical properties. There are short fibers and filaments in physical form. It can be used to weave various fabrics and non-woven products. Textiles are generally underwear, casual wear, bedding, etc., and the fabrics made of it Soft to the touch, stable in shape, wi...
