specific Embodiment approach

[0025] The present invention uses PET and PTT composite yarn as raw material blended yarn and its preparation method, which includes two contents of product and method; the product includes four specific implementation methods: first, a blend of PET and PTT composite silk fiber Yarn, in which the content of PET and PTT composite filament is greater than 0 and less than or equal to 100%; followed by PET and PTT composite filament staple fiber and cotton / linen blended yarn; thirdly, PET and PTT composite filament staple fiber and viscose, modal, Lyocell, Tencel and other cellulose fiber blended yarns; finally, PET and PTT composite yarns and wool, cashmere, and cellulose fiber multi-component blended yarns.

[0026] The preparation method of the present invention is similar to the traditional spinning process, but due to the particularity of the formula of the present invention, the preparation method specifically includes mixing, cleaning, carding, drawing, coarse sand and fine ...

Embodiment 1

[0039]Example 1 (the production of 16S / 1 combed weaving yarn blended with PET and PTT composite silk fibers and cotton as an example):

[0040] Raw materials: 1. PET and PTT composite yarn 1.8dtex*38mm; 2. Xinjiang cotton: grade 2, main body length 29mm.

[0041] The blending ratio is: PET and PTT composite yarn 60%, combed cotton 40%.

[0042] Process route: PET and PTT composite yarn and Xinjiang cotton mixed - plucking machine - cotton opener - packaging - plucking machine - cotton opener - lapping machine - carding machine - pre-drawing 1 - coiler - combing machine -drawing 1-drawing 2-roving-spinning-winding-packing.

[0043] Process parameters: PET and PTT composite yarns are blended with combed cotton in the way of box blending. Blowing A076 combined beater speed 900r / min, fan speed 1300, beater and balance roller gauge 10, lap roller speed 110r / min, porcupine beater speed 500r / min, AC2525*01350 993 teeth / AD4030*01890P 398 teeth / square inch for doffer card clothing ...

Embodiment 2

[0045] Embodiment 2 (the combed siro-spun weaving yarn of 16S / 1 blended with PET and PTT composite silk fiber and cotton is an example):

[0046] Raw materials: 1. PET and PTT composite yarn 1.8dtex*38mm; 2. Xinjiang cotton: grade 2, main body length 29mm.

[0047] The blending ratio is: PET and PTT composite yarn 60%, combed cotton 40%.

[0048] Routing:

[0049] Process route: PET and PTT composite yarn and Xinjiang cotton mixed - plucking machine - cotton opener - packaging - plucking machine - cotton opener - lapping machine - carding machine - pre-drawing 1 - coiler - combing machine -drawing 1-drawing 2-roving-spinning siro spinning-winding-packing.

[0050] Process parameters: PET and PTT composite yarns are blended with combed cotton in the way of box blending. Blowing A076 combined beater speed 900r / min, fan speed 1300, beater and balance roller gauge 10, lap roller speed 110r / min, porcupine beater speed 500r / min, AC2525*01350 993 teeth / AD4030*01890P 398 teeth / sq...

Abstract

The invention discloses a blended yarn made of a PET (polyethylene terephthalate) and PTT (polytrimethylene terephthalate) composite filament and a preparing method thereof. The blended yarn comprises stable fibers of the PET and PTT composite filament; the content of the staple fibers is greater than 0 and not greater than 100%. The blended yarn further comprises a mixed component not less than 0 and less than 100%. The mixed component is cotton, hemp, cellulose fiber, or multi-component mixture of wool, cashmere and cellulose fiber. The preparing method includes mixing, cleaning, combing, drawing and doubling, roving and spinning; the mixing step is to mix the stable fibers of the PET and PTT composite filament and the mixed component; a cleaning beater for pre-spinning is a combing needle.

Description

technical field [0001] The invention relates to a blended yarn and a spinning process thereof, in particular to a novel fabric composition and a preparation method thereof. Background technique [0002] For fabrics and the clothes made of them, we are committed to making them more comfortable to wear. Specifically, the comfort, touch, quality, quick-drying effect and free There is a lot of room for improvement in ironing ability; [0003] At the same time, PET and PTT composite yarn is a new polyester fiber with excellent softness, bulkiness, elasticity, and elastic recovery, and has broad application prospects. [0004] However, its fibers are often crimped and its elasticity is not well controlled so that it has not been well utilized in the textile field at present. Contents of the invention [0005] The technical problem to be solved by the present invention is to provide a kind of blended yarn with PET and PTT composite yarn as raw material and its preparation metho...
