Embodiment 1

[0023] Embodiment 1 uses vortex spinning noil fiber to carry out short process yarn formation.

[0024] The main body length of the vortex spinning noil fiber is 18 mm, which belongs to ultra-short fiber, and it is difficult to use the traditional textile process to form and spin. Therefore, the vortex spinning noil fiber and polypropylene fiber are first mixed and carded at a ratio of 80 / 20. , forming into a web by acupuncture method, heat-bonded and solidified reinforced fiber web to obtain a non-woven surface material package made of ultra-short cotton fiber raw materials with a gram weight of 20 grams per square meter; , the specific steps are:

[0025] A non-woven surface material is cut into fiber strips

[0026] The non-woven surface material rolls with a surface density of 20 g / m2 made from the noil fiber raw material are placed on a non-woven fabric slitting machine, and the non-woven surface material is cut into a roll with a linear density of 70 g / km. For fiber st...

Embodiment 2

[0029] Embodiment 2 uses kapok tow to carry out short-process yarn formation.

[0030] Kapok fiber is the fruit fiber of the kapok plant of Malvaceae, generally about 8-32mm in length and 20-45μm in diameter. It is the thinnest, lightest, highest hollow and warmest fiber material among natural ecological fibers. It has 1 / 2 of cotton fiber, but the hollow rate is over 86%, which is 2-3 times that of ordinary cotton fiber. , warmth, strong hygroscopicity and other characteristics, widely used in various home textile products. However, due to its short length, low strength, poor cohesion and lack of elasticity, kapok fiber is difficult to spin alone, resulting in great limitations in its application in textiles. When kapok fiber and cotton fiber are blended and spun, the shorter and finer the kapok fiber is, the easier it is to form fly and tow. Therefore, the length of the main body of kapok tow is shorter, 10-12 mm long, which belongs to ultra-short fiber, and it is difficult...

Abstract

The invention relates to a short-process yarn forming method of ultra-short difficult-spinning fibers, which belongs to the technical field of textiles. The invention makes use of the characteristics that ultra-short fibers are easy to make into non-woven surface materials. The non-woven surface material rolls made of ultra-short and difficult-to-spin fiber raw materials are installed on the cutting machine, and the non-woven surface materials are cut into fiber strips, which can be quickly A strip-shaped difficult-to-spin ultra-short fiber prepolymer is made, and then the strip-shaped difficult-to-spin ultra-short fiber prepolymer is directly twisted and wound by using the ring spindle twisting and winding action of the ring spinning frame that cancels the drafting system. Continuously transforming into linear cylindrical yarns, the yarn forming method of the present invention breaks the technical bottleneck that ultra-short fibers are difficult to collect into slivers by traditional carding, changes the structure of fiber strips, and eliminates a series of processes such as drawing and roving, effectively The problem that the difficult-to-spin ultra-short fiber cannot be formed into a yarn is solved. The method of the invention has a short process flow and is easy to popularize and apply.

Description

technical field [0001] The invention relates to a short-process yarn forming method of ultra-short difficult-spinning fibers, which belongs to the technical field of textiles. Background technique [0002] Textile fabrics used in clothing can be divided into three categories: woven (woven), knitted and non-woven fabrics. Woven and knitted fabrics are woven from yarns or filaments through a weaving process; non-woven fabrics (also known as non-woven fabrics) are processed from textile fibers by bonding, fusing or other mechanical and chemical methods. Woven fabric is a fabric formed by interweaving warp yarns and weft yarns perpendicularly to each other. The fabric weaves include plain weave, twill weave, satin weave and the weaves formed by the above three basic weaves and their intersecting changes. Knitted fabrics are formed by forming yarns or filaments into coils, and then interlocking the coils. Due to the coil structure of knitted fabrics, there is a large amount of y...
