Embodiment 1

[0010] Product specifications: 21 counts core-spun yarn, acrylic fiber + 100D glass fiber filament core-spun yarn, the blending ratio is 60% acrylic fiber and 40% glass fiber filament, used for knitting and weaving.

[0011] The production process is as follows: the acrylic fiber is individually packaged, and after opening and cleaning (A200 type grabbing machine → A006B cotton box mixing machine → A036 type cotton opener → A092A type cotton box feeding machine → A076C type single beater hand roll Machine) → A186D carding machine → A272 type draw frame head parallel → A272 type draw frame two parallel → A272 type draw frame three parallel, make sliver separately, the sliver quantitative is 3.06g / m; The fiber slivers and fiberglass filaments are fed into the same nozzle of MURATEC NO.802HR air-jet spinning equipment. The process parameters are: the first nozzle pressure is N1=0.23MPA; the second nozzle pressure is N2=0.42MPA; the feeding ratio of the first output roller to the ...

Embodiment 2

[0013] Product specifications: 11 core-spun yarns, acrylic fiber + 198D glass fiber filament core-spun yarn, the blending ratio is 60% acrylic fiber and 40% glass fiber filament; used for woven fabrics.

[0014] The process is as follows: pack the acrylic fiber separately, after opening and cleaning (A200 type grabbing machine → A006B cotton box blending machine → A036 type cotton opener → A092A type cotton box feeding machine → A076C type single beater lapping machine )→A186D carding machine→A272 type drawing frame head paralleling→A272 type drawing frame two paralleling→A272 type drawing frame three paralleling, make slivers separately, the sliver weight is 5g / m; then the acrylic fiber Sliver and glass fiber filaments are fed into the same nozzle of MURATEC NO.802HR air-jet spinning equipment. The process parameters are: the first nozzle pressure is N1=0.35MPA; the second nozzle pressure is N2=0.45MPA; the feeding ratio of the first output roller to the front roller is 0.98;...

Embodiment 3

[0016] Product specifications: 32 core-spun yarns, acrylic fiber + 66D glass fiber filament core-spun yarn, the blending ratio is 60% acrylic fiber and 40% glass fiber filament, used for woven fabrics.

[0017] The process is as follows: pack the acrylic fiber separately, after opening and cleaning (A200 type grabbing machine → A006B cotton box blending machine → A036 type cotton opener → A092A type cotton box feeding machine → A076C type single beater lapping machine )→A186D carding machine→A272 type drawing frame head paralleling→A272 type drawing frame two paralleling→A272 type drawing frame three paralleling, make sliver separately, the sliver weight is 2.7g / m; Fiber slivers and glass fiber filaments are fed into the same nozzle of MURATEC NO.802HR air-jet spinning equipment. The process parameters are: the first nozzle pressure is N1=0.20MPA; the second nozzle pressure is N2=0.4MPA; the feeding ratio of the first output roller to the front roller is 0.98; the winding of t...

Abstract

The invention discloses an air-jet spinning processing method for modacrylic fiber and glass fiber core-spun yarn, which comprises the following steps: cleaning a modacrylic fiber, carding the modacrylic fiber, or carrying out the chute feeding of the modacrylic fiber; then separately making into strips of 2g / m-4g / m through the drawing processes of head drawing, second drawing and third drawing, then simultaneously feeding the strips of the modacrylic fiber and the glass fiber filament into the same nozzle of the air jet spinning, and taking out from the second nozzle and winding into the modacrylic fiber and the glass fiber core-spun yarn; the process parameters are as follows: the pressure of the first nozzle is M1=0.2-0.35 MPA; the second nozzle pressure is N2=0.4-0.5MPA; the feeding ratio is 0.97-0.99; the winding ratio is 0.98-1.00; the nozzle N1 is of H3 type; N2 is of H3-H40; the temperature of the air jet spinning workshop is controlled between 25-28 DEG C; RH is 40-55%. The air-jet spinning processing method for modacrylic fiber and glass fiber core-spun yarn changes a plurality of process parameters in the production process, so that the product not only can resist pilling, but also has high strength and better softness.

Description

technical field [0001] The invention belongs to the field of cotton spinning engineering, and more specifically relates to an air-jet spinning processing method for acrylic and glass fiber core-spun yarns. Background technique [0002] Application number is that the Chinese patent of 2006100265807 discloses a kind of acrylic fiber and glass fiber core-spun yarn and air-jet spinning processing method thereof, acrylic fiber is through opening cleaning, carding, or through clearing steel; And, in the three-drawing process, make 2g / m-4g / m sliver separately, and then feed the acrylic fiber sliver and glass fiber filament into the same nozzle of air-jet spinning at the same time, from the second nozzle It is wound into acrylic and glass fiber core-spun yarn; the process parameters used are: the first nozzle pressure is N1=0.35-0.40MPA; the second nozzle pressure is N2=0.50MPA; the feed ratio is 0.99-1.00 ; The winding ratio is 0.98-1.00; the nozzle N1 is H3 type; N2 is H3-H40; wh...
