The melt is quantitatively extruded through a metering pump arranged in a spinning box body, and a small hole with a spinneret is formed into a melt trickle, and the melt trickle is cooled and solidified in a cooling blowing environment at a lower temperature after being used, so as to form the nascent fiber. The primary fiber is oiled and wound into a cylinder after being networked. The coiled wire is subjected to secondary forming processing such as subsequent stretching, heat setting and the like to obtain the finished fiber with applicability.

Preparation of a kador spandex mixed weaving layer 2: a process for spinning chemical fibres by dissolving a polymer in a solvent, spraying a fine stream through a spinneret orifice and into a coagulation bath. Fiber-forming polymers suitable for wet spinning have decomposition temperatures below the melting point or are susceptible to discoloration upon heating and are soluble in suitable solvents. Synthetic fibers such as polyacrylonitrile fibers, polyvinyl alcohol fibers and the like, viscose fibers, cuprammonium fibers and the like and artificial fiber varieties are produced by wet spinning. The fiber section obtained by wet spinning is mostly non-circular, and has a more obvious sheath-core structure, which is mainly caused by the solidification of the coagulating liquid.

Preparing a fibrilia polyester mixed weaving layer 3:

a gas singeing machine; and (3) fuel: gasoline, natural gas; the fire hole is positive and negative, and double-sided singeing is carried out; vehicle speed: light and thin fabrics 100-120 m/min, and heavy fabrics 80-100 m/min; the distance between the fabric and the reducing flame is 0.8-1.0 cm; the gasification amount of gasoline is 20-25 kg/h, the gasification temperature is more than or equal to 80 ℃, and the air pressure is 9.0 multiplied by 103Pa.

The purpose of scouring is to remove oils and impurities from the fibers. Using caustic soda, degreasing agent, scouring agent and other auxiliary agents to dissolve, degrade, dissolve and other actions in alkaline bath at a certain temperature, so that part of impurities of the fabric are directly dissolved in the scouring liquid; part of impurities are reduced due to the binding force between the swelling and the fiber, and are separated from the fabric through washing; a portion of the impurities are stripped from the fabric by the solubilization of the surfactant.

The process conditions are as follows: 3-5 g/L of caustic soda, 1-1.5 g/L of degreasing agent, 1-2 g/L of scouring agent, 110-120 ℃ and 30-50 min of treatment time. The alkali corrosion on the surface of terylene during alkali decrement treatment reduces the mass, the diameter of fiber is reduced, pits are formed on the surface, the rigidity of fiber is reduced, the aurora of terylene yarn is eliminated, the gaps of interweaving points of fabric are increased, the fabric has soft hand feeling and soft luster, and the moisture absorption and sweat release performance are improved. The alkali deweighting treatment utilizes the peeling effect of caustic soda on terylene to improve softness and fuzzing and pilling performance.

Two-bath method, disperse dye dyeing, temperature 130-135 ℃ and heat preservation time 40-50 min; medium-temperature reactive dye dyeing, temperature of 60 ℃ and heat preservation time of 40-60 min.

In the dyeing and finishing process, textiles are subjected to wet heat treatment by various chemical reagents and are subjected to the actions of mechanical tension and the like, so that not only is the organization structure changed, but also the textile can cause stiff and rough hand feeling, and soft finishing can make up for the defect, so that the textile is soft in hand feeling. Chemical softening is a softening agent to reduce the coefficient of friction between fibers to achieve a softening effect.

The process conditions are as follows: 20-50 g/L of hydrophilic amino organosilicon softener, 10-15 g/L of antistatic agent, 170-180 ℃ and overfeeding of 1-3% at a speed of 35-45 m/min. And (5) calendaring. The plasticity of the fiber under the damp and hot condition is utilized to flatten the surface of the fabric so as to improve the luster of the fabric. The yarn is flattened after the fabric is rolled, the surface is smooth, the luster is enhanced, and the hand feeling is stiff.

Example 2

The embodiment comprises the following steps: the preparation process of the flax layer 4 and the superfine denier polyethylene fiber layer 5 and the antibacterial fiber layer 6 as the filling layer comprises the following steps:

preparation of linen layer 4: the wheel blades or the threshing plate are of wooden structures and are fixed on the axle and the wheels to form a threshing impeller, the quality standard of each wheel blade is required to be consistent when the wheel blades are manufactured, the threshing vertical partition plate is vertically arranged in front of the threshing impeller, and the upper part of the plate is provided with a hemp inlet. The worker holds the hemp stems by hand, feeds the hemp stems into the impeller rotating at high speed from the mouth, breaks the hemp stems into pieces, and then makes the pieces into hemp. The process of making hemp by using hand wheel is characterized by that the stem is divided into raw stem bundles whose diameter is 30-40mm, the root portion of stem is required to be ordered, and three processes of primary beating, middle beating and fine beating are respectively passed through the hemp beating blade, and the stem is crushed, and the impurity on the fibre is removed so as to obtain the invented industrial long hemp fibre. The flax that falls in the process of processing the dry stems becomes flax second coarse after mechanical treatment. The second coarse flax is processed by a short flax beater to obtain cotton flax with the average fiber length of 30-40mm and the impurity content standard of less than 3 percent, commonly called flax cotton. The unravelled flax falls down or falls down after being manually carded, and is commonly called flax-one thick. Flax one and flax two are also known as coarse flax. The flax cotton processed by flax two-coarse processing can be used for spinning flax/cotton blended yarn in cotton spinning industry.

Preparation of superfine denier polyethylene fiber layer 5:

the activated cellulose is put into an acetylating agent formed by sulfuric acid and acetic acid for acetylation, the cellulose triacetate after the acetylization is partially saponified to improve the solubility of cellulose in an internal ketone solution, meanwhile, the molecular weight of the cellulose is reduced to a certain extent, a certain amount of precipitant is added into the mixture after the preparation to precipitate cellulose diacetate, then the solvent is evaporated to precipitate the cellulose diacetate, the residual acetic acid is removed by washing, the residual sulfuric acid is removed by stabilizing treatment, and finally, the cellulose diacetate is prepared by squeezing, drying and crushing.

Preparation of the antibacterial fiber layer 6:

chemical modification method:

the antibacterial fiber prepared by spinning is subjected to modification treatment on the red-dimensional surface, and is combined with groups with antibacterial action through coordination chemical bonds or other types of chemical bonds, and charged functional groups are generated on the fiber of the fabric by utilizing grafting, homopolymerization and copolymerization methods, and then the fiber is immersed into a counter ion solution for treatment, so that the antibacterial groups are grafted on the fiber. The preparation of the antibacterial fiber by chemical grafting modification is generally carried out in two steps; firstly, carrying out surface treatment on the fiber, so that an action point capable of being grafted with an antibacterial group compound is generated on the surface of the fiber, and a chemical solvent treatment method is a commonly used method at present; and secondly, combining the compound with the antibacterial group with the treated fiber to obtain the antibacterial fiber, or utilizing active groups existing on the fiber and the antibacterial agent to carry out a crosslinking reaction under certain conditions to fixedly view the antibacterial agent on the fiber.

The spinning oil is added with an antibacterial agent to prepare antibacterial fibers, and the antibacterial fibers are required to be guided onto a winding tube through a yarn guiding disc and then drawn through a drawing roller in the spinning drawing process. In these processes, friction is generated between the yarn and the silver guide, which affects the spinning quality. The surfactant is added as the oil agent in the spinning process to reduce friction, but at the same time, the oil agent is easy to grow fungi, so that the antibacterial agent is added at the stage to enable the antibacterial agent to penetrate into the fiber under the action of the surfactant, thereby inhibiting the influence of microorganisms on the fiber.

When an antibacterial agent is added for spinning during spinning sizing, the warp yarns need to be sized in order to make the yarn support withstand the tension and friction in the weaving process and give the fabric good hand feeling. The fibers for warp yarns include natural fibers, chemical fibers, staple yarns, blended yarns, long fiber yarns, and mixed filaments. The sizing agent is also selected according to the type of warp yarn and the purpose of use, and is mainly natural sizing agent of far powder type, and is also commercially available synthetic and semi-synthetic. Regardless of the type of slurry used, various additives such as a hygroscopic agent and a color-finding agent are added to some of the slurry. These adjuvants also tend to produce a variety of microorganisms, and therefore require the addition of antimicrobial agents.
