[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example See also Figure 1-2 As shown, a method for producing an anti-pilling knitted fabric comprises the following steps: Step 1: Raw material selection and blending; Specifically, high-quality modified polyester fiber is selected, accounting for 45%. The modified polyester fiber has a low pilling tendency and high physical properties after special processing, which further enhances the anti-pilling performance, wear resistance and elasticity of the fabric; high-quality wool fiber is selected, accounting for 25%. Although wool fiber has good warmth retention and breathability, too high a proportion may aggravate the pilling problem. The proportion of wool fiber should be appropriately reduced to balance the warmth retention, comfort and anti-pilling performance of the fabric; nylon fiber is selected, accounting for 20%. Nylon fiber can enhance the wear resistance and elasticity of the fabric; mercerized velvet is selected, accounting for 10%. Mercerized velvet has better anti-pilling performance and softness, while maintaining the moisture absorption, breathability and wearing comfort of the fabric; The raw materials are cleaned, degreased and dried, and then the prepared fibers are sent to the blending machine for blending. During the blending process, pay attention to controlling the temperature and humidity of the equipment, as well as parameters such as blending speed and time to ensure a good blending effect. After the blending is completed, the blended yarn is subjected to necessary inspection and testing to ensure that its quality meets production requirements.

[0020] Step 2: yarn pretreatment; Specifically, yarn pretreatment includes: singeing and shearing. Singeing is to send the blended yarn into a singeing machine to remove the fluff and impurities on the yarn surface; shearing is to send the singed yarn into a shearing machine to remove the hairiness on the yarn surface. Singeing and shearing treatments can improve the smoothness of the yarn and reduce the tendency to pilling; heat setting is to send the yarn into a heat setting machine to heat set the yarn. Heat setting treatment can inhibit the pilling effect on the fabric surface and improve the overall performance of the fabric; pretreatment agent treatment is to use an efficient and environmentally friendly pretreatment agent, such as a new tri(2-carbonylethyl)phosphine hydrochloride solution or other pretreatment agents with stronger permeability and adhesion, to pretreat the yarn at an appropriate temperature (45-55°C), time (20-30 minutes) and bath ratio (1:25-1:35) to ensure that the pretreatment agent fully penetrates into the yarn fiber. After the pretreatment is completed, the fabric is taken out and necessary cleaning and drying treatments are carried out.

[0021] Step 3: yarn weaving; Specifically, yarn weaving includes using a computer flat knitting machine to weave the pretreated yarn into plain or twill weaving fabrics. The computer flat knitting machine is a modern knitting equipment with the advantages of high degree of automation, fast weaving speed and high production efficiency. Plain woven fabrics have a stable structure and moderate elasticity, and are suitable for making various garments and household items. Twill woven fabrics have better elasticity and breathability, and are suitable for making sportswear, casual wear, etc.

[0022] Step 4: Arrangement and special treatment; Specifically, finishing and special treatments include: bio-enzyme treatment, sending the fabric into the enzyme treatment tank, allowing the bio-enzyme solution to fully act on the surface of the blended yarn, and using the hydrolysis of the enzyme to remove the fuzz and fiber ends on the surface of the fabric. Bio-enzyme treatment can remove the fuzz and fiber ends on the surface of the yarn and reduce the tendency of pilling; resin finishing, using high molecular polymers such as polyacrylate compounds, polyurethane (PU) or organic silicone resins as anti-pilling resin finishing agents, so that the resin finishing agent forms a protective film on the fiber surface to improve the wear resistance and anti-pilling performance of the fiber; dyeing treatment, dyeing the fabric to improve the color brightness of the fabric; softening finishing: using softener to soften the fabric to improve the softness and wearing comfort of the fabric; antibacterial finishing: adding antibacterial agent to treat the fabric with antibacterial, so that the fabric has antibacterial and antibacterial functions; waterproof finishing: using waterproof agent to waterproof the fabric to make the fabric waterproof and anti-fouling functions.

[0023] Step 5: Clean and dry.

[0024] Specifically, cleaning and drying include: first use high-efficiency cleaning methods such as high-pressure water gun cleaning or ultrasonic cleaning to clean the fabric to ensure that impurities and finishing liquid residues on the fabric surface are completely removed; then, dry the fabric at an appropriate temperature (60-75°C) to ensure that the fabric is dried evenly to avoid excessive damage and deformation; then, conduct a comprehensive test on the finished fabric for anti-pilling grade, moisture absorption, breathability and other indicators to ensure that the quality of the fabric meets the design requirements and quality standards.

[0025] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
