 var ListView = Backbone.View.extend({
    el: $('body'),
    events: {
        'click button#add': 'addItem'

    },
    initialize: function () {
        _.bindAll(this, 'render', 'addItem', 'appendItem');

    },

    render: function () {
        $(this.el).append("<button id='add' class='btn btn-primary clear'>Add Items</button>");
        $(this.el).append("<ul class='ul_adjust'></ul>");
        _(this.collection.model).each(function (item) {
            appendItem(item);
        }, this);
    },

    addItem: function () {

        var item = new Item();
        item.set({
            part1: $("#name").val()
        });

        this.collection.add(item);
    },
    appendItem: function (item) {
        var itemView = new ItemView({
            model: item
        });

        $('ul', this.el).append(itemView.render().el);
    },


});

Your events is setup so that when you click the #add button, it calls the addItem function. So you just need to clear the textbox #name in this same function.

I would simply do:

$("#name").val("");

at the end of your addItem function, after this.collection.add(item); so the value is only cleared when you no longer need it.
