Embodiment 1

[0009] Example 1 : produce 60 S Honeycomb Structure Polyester Modified Fiber Pure Spinning Yarn

[0010] 1. Raw material: honeycomb structure polyester modified fiber: 1.33dtxe×38mm;

[0011] 2. Process flow:

[0012] Raw material processing→blowing→carding→drawing→roving→spinning→winding.

[0013] 3. Specific process:

[0014] Processing of raw materials: The raw materials are placed in loose bags for 24 hours in an environment with a relative humidity of 72-80%;

[0015] Blowing process: adopt short process and comb needle beater, mainly soft loosening and combing, the speed of the roll machine beater is controlled within 850r / min, blowing temperature: 18°C-32°C, relative humidity: 65%-80 %.

[0016] Carding process: The speed of the carding licker-in roller is less than 750r / min, the 2520 series cylinder card clothing is used, the MCH36 flat card clothing is used, and the neps are controlled within 2 grains / gram.

[0017] Drawing process: a total of two drawing (refe...

Embodiment 2

[0021] Example 2 , production 32 S Honeycomb structure polyester modified fiber 50% and cotton fiber 50% blended yarn

[0022] 1. Raw material 1: honeycomb structure polyester modified fiber: 1.33dtxe×38mm;

[0023] Raw material 2: JC cotton: grade 2.2, count 5800, main body length 29mm.

[0024] 2. Process route:

[0025] The front process of raw material 1: polyester modified fiber with honeycomb structure → grasping cotton → mixing cotton → rolling → carding;

[0026] Raw material 2 front process: JC cotton→grabbing cotton→mixing and opening→rolling→carding→pre-drawframe→sliver and coiler→combing;

[0027] Mix raw materials 1 and 2: honeycomb structure polyester modified fiber raw sliver / JC cotton sliver mixed first drawing frame → second drawing frame → third drawing frame → roving → spun yarn → winding.

[0028] 3. Process parameters:

[0029] The combing process is added to JC cotton, and the polyester modified fiber with honeycomb structure and JC cotton sliv...

Embodiment 3

[0032] Embodiment 3, Production 40 S Honeycomb structure polyester modified fiber 40% and modal fiber 60% blended yarn

[0033] 1. Raw material 1: honeycomb structure polyester modified fiber: 1.33dtxe×38mm;

[0034] Raw material 2: Modal fiber: 1.33dtxe×38mm;

[0035] 2. Process route:

[0036] Honeycomb structure polyester modified fiber / modal fiber→grabbing cotton→mixing and opening→multi-compartment blending→rolling→carding→first drawing→second drawing→roving→spinning→winding.

[0037] 3. Process parameters

[0038] What is different from Example 1 is the cleaning process, because cotton boxes are used to mix cotton, therefore: (1) the arrangement of cotton bales in the bale grabbing machine and the two fibers should be evenly arranged in proportion; The fibers are more evenly mixed; the basis weight of the roving is 4.8g / 10m, the twist coefficient is 82; the twist coefficient of the spun yarn is 360. Other parameters are the same as in Example 1.

Abstract

Disclosed are cellular polyester modified fiber pure and blended yarns and a production process thereof. The fibers are made of cellular polyester modified fiber pure yarns or made by blending the cellular polyester modified fiber pure yarns with more than one of other fibers. Other fibers include cotton fibers, viscose fibers, modal fibers, rose fibers, chitin fibers, wool, cashmere and spun silk yarns. According to a mass ratio of blending, the cellular polyester modified fibers account for 30%-80%, and other fibers account for 70%-20% and 16S-180S in count. The cellular polyester modified fiber pure and blended yarns have the advantages that the novel cellular polymer modified fibers can be produced with conventional equipment in cotton mills while the best process parameters are mastered, the produced cellular polyester modified fiber pure yarns or various blended yarns and finished fabric products can be used for developing high-class clothing and related products, and the pure yarns and the blended yarns are different in style and have respective characteristics.

Description

technical field [0001] The patent of the invention relates to the spinning process in textile engineering, specifically a pure spinning and blended yarn of polyester modified fiber with honeycomb structure and its production process. Background technique [0002] Ordinary polyester fiber has poor hygroscopicity, the moisture regain rate is 0.4-0.5% under standard conditions, and the moisture regain rate is 0.6-0.8% when the relative humidity is 100%, so the fiber performance does not change much under dry and wet conditions; Since the fiber has no hydrophilic groups and the molecules are tightly packed, it is difficult for the dye molecules to enter the interior and cannot be dyed by general methods; at the same time, the polyester fiber has high strength and good elastic recovery performance. The above-mentioned performance characteristics lead to poor wearing performance and dyeing performance of ordinary polyester fibers, and they are stiff and airy when used as underwear...
