Linen products are moisture-absorbing and breathable, comfortable and pleasant, naturally antibacterial, anti-radiation and non-static, green and environmentally friendly, and beneficial to health. More and more consumers are eager to wear them. However, due to Linen products The product also has defects such as rough and hard feel, easy wrinkles when worn, large shrinkage and hardening after washing, poor dyeability, and easy weft skew in knitted products. In addition, consumers stay away from it because it is difficult to meet people’s aesthetic habits and pursuits of clothing. The requirement for the perfect combination of product intrinsic quality and form. Therefore, exploring the use of high and new technologies to make up for the shortcomings of natural fiber products such as flax and meeting the market needs of consumers has become an issue of current economic value and urgent need to be solved. In view of the above reasons, special finishing of linen fabrics is particularly important.
At present, according to the use of linen fabrics, today we mainly bring you the soft finishing and shrink-proof finishing of linen fabrics.
1 Thermal setting of linen fabrics. Heat setting uses the plasticity of linen fabrics in hot and humid conditions to slowly pull the fabric width to the finished width, thereby eliminating internal stress, making the fabric width uniform, and adjusting the warp yarns. Correct the weft skew and stabilize the size and shape of the fabric to achieve the shaping effect of the weft yarn in the fabric. p style=”margin: 0px; padding: 0px; max-width: 100%; clear: both; min-height: 1em; color: rgb(62, 62, 62); font-family: ‘Helvetica Neue’, Helvetica, ‘Hiragino Sans GB’ , ‘Microsoft YaHei’, Arial, sans-serif; font-size: 16px; line-height: 25px; background-color: rgb(255, 255, 255); box-sizing: border-box !important; word-wrap: break-word !important;”>
2 Soft finishing for linen fabrics Flax fiber has a certain degree of softness because it contains oil and wax, but it has been basically removed during pre-treatment processes such as pickling, scouring and bleaching. Moreover, after these chemical processes are dried, the chemical Medicines often remain on fabrics, making linen fabrics The feel of linen fabric is relatively rough. In addition, because linen fabric itself has a relatively firm feel, sometimes linen fabrics, especially knitted underwear, need to be softened, but the finishing degree must be appropriate, otherwise, the fabric will lose its proper texture. Bone. Therefore, in soft finishing, especially woven fabrics, Sometimes it is necessary to add some stiffening agent. How to make linen fabric soft so that the close-fitting summer clothing can be comfortable in contact with the skin without losing the crispness of linen clothing. This is the key point in soft finishing of linen. Problems solved. In recent years, we have promoted linen sweater technology. Through the practice of the project, we have accumulated a lot of experience and made breakthroughs in the softening and shrink-proof finishing of linen knitted fabrics. We first treated the linen fabric with cellulase and then finished it with amino silicone, which can significantly reduce the stiffness of the fabric. , the softness is increased, and a soft and smooth feel is obtained. The softness effect is veryIdeally, this treatment works extremely well for linen knitted underwear. In knitting, we usually soften the fully formed knitted pieces or woven gray fabrics, while in weaving, we usually combine it with hot air setting at the same time. In order to improve the feel of the finished fabric, in the anti-wrinkle finishing process , also add a certain amount of softener. At present, the commonly used softeners for softening and finishing linen fabrics are softeners vs. silicone softening agents. However, the amount of softener must be appropriate, otherwise it will not only have a softening effect, but also a water-repellent effect.
3 Anti-shrink finishing of linen fabrics.Whether it is a linen knitted fabric or a woven fabric, if it is wetted with water again in a relaxed state, it will shrink significantly. If the fabric is made of fabric whose size is not yet stable, after washing, it will shrink to a certain extent. shrinkage, which will cause the clothing to deform or lose shape, causing consumers Therefore, the anti-shrinkage treatment of fabrics is particularly important in stabilizing the dimensional stability of fabrics. Since the main cause of fabric shrinkage is the change of fabric shrinkage, the basic principle of anti-shrinkage treatment of fabrics is to ensure that the fabric becomes a product. Previously, certain mechanical treatments were used to make the weft density and warp density of the fabric The fabric shrinkage in the direction is increased to a certain extent, so that the fabric has a relaxed structure. Not only does the fabric after drying and setting deformation be smaller, but also when the fabric swells after being moistened, due to the remaining space between the warp yarn and the weft yarn. If there is enough room or gap, it will not cause the shortening of the warp length of the fabric and the weft length of the fabric. Directional shrinkage is actually to pre-shrink the existing potential shrinkage of the fabric before it becomes the finished product, which can significantly reduce the shrinkage rate of the finished product. This method is called mechanical pre-shrinkage finishing. Currently, linen factories mainly use compression-type shrinkage. Shrinking machine for mechanical pre-shrinking.
